d19002 | test | I had to add the following Nuget packages:
MSTest.TestAdapter
MSTest.TestFramework
Microsoft.NET.Test.Sdk
Visual Studio release notes
A: Ok, you can add Nuget packages as asked. But you can also try to disable the following setting (Tools->Options->Test):
"For improved performance, only use test adapters in test assembly folder or as specified in runsettings file".
Let me know if it works for you.
A: If you are using MS Test, try installing
MSTest.TestAdapter via nuget or
if you are using nunit, install
NUnit3TestAdapterlatest versions via nuget.
After installing please restart the visual studio and then you can see the tests running.
A: I had the same issue and none of the answers above worked.
Installing NUnit3TestAdapter V3.10.0 fixed it.
A: I had a very similar issue recently with xUnit, the same outcome, however my fix was due to the fact that previously with lower versions of Microsoft.NET.Test.Sdk you didn't need XUnit.Runner.VisualStudio explicitly installed.
When I updated my Microsoft.NET.Test.Sdk to version 15.9.0 it stopped allowing tests to run until I installed the XUnit.Runner.VisualStudio Nuget.
Now, This may seem blatantly obvious, but, previously it would cope without it and still work. Now, it does not. The same will probably be true of other test platforms. It worked for me.
A: My reputation score does not currently allow me to add this as a comment to the accepted answer. For reference, I've appended version numbers to the nuget packages referenced in csharpsql's answer:
MSTest.TestAdapter v1.3.2
MSTest.TestFramework v1.3.2
Microsoft.NET.Test.Sdk v15.9.0
A: I know that it is stupid, but for me nothing from earlier answers were working. After that I just restart my computer and everything is working correctly :)
(My proble was that one day everything was working correctly and next day it stopped working)
A: For me I felt very foolish after spending hours, trying EVERYTHING, only to find that I had simply forgotten to add the [TestMethod] directive on the unit test method.
A: I was trying to run an existing project. I had the .NET Core SDK 3.3 installed, but did not have 2.1 installed. This was causing the tests to silently fail.
A: I ran into this problem too (in VS 2019), which can be found all over the web.
I also support @csharpsql's simple solution.
I also couldn't directly comment (how annoying Stack Overflow!)
I had used 'Remove unused references' in VS.
I did have to restart VS to get the references removed from view.
Cleaning and rebuilding posed no problem.
But running all tests from the Test Explorer reported 'Not run' on all tests, without any explanation or error message. Very annoying.
After finding the suggestion here I started experimenting with re-adding the latest versions of those 3 references.
That solved my problem.
I just remains annoying this unnecessary problem occurs!
A: Adding NuGet packages doesn't work for me.
Disable the following setting (Tools->Options->Test): "For improved performance, only use test adapters in test assembly folder or as specified in runsettings file" works.
A: Since its just a checkbox, Ive tried disabling the following setting before anything else, and it worked!

d19003 | test | You first file is overwritten by the second call to the function | unknown | |
d19004 | test | I would just suggest manually reading/writing the members of the struct individually. Packing using your compiler directives can cause inefficiency and portability issues with unaligned data access. And if you have to deal with endianness, it's easy to support that later when your read operations break down to field members rather than whole structs.
Another thing, and this relates more to futuristic maintenance-type concerns, is that you don't want your serialization code or the files people have saved so far to break if you change the structure a bit (add new elements or even change the order as a cache line optimization, e.g.). So you'll potentially run into a lot less pain with code that provides a bit more breathing room than dumping the memory contents of the struct directly into a file, and it'll often end up being worth the effort to serialize your members individually.
If you want to generalize a pattern and reduce the amount of boilerplate you write, you can do something like this as a basic example to start and build upon:
struct Fields
{
int num;
void* ptrs[max_fields];
int sizes[max_fields];
};
void field_push(struct Fields* fields, void* ptr, int size)
{
assert(fields->num < max_fields);
fields->ptrs[fields->num] = ptr;
fields->sizes[fields->num] = size;
++fields->num;
}
struct Fields s_fields(struct s* inst)
{
struct Fields new_fields;
new_fields.num = 0;
field_push(&new_fields, &inst->i1, sizeof inst->i1);
field_push(&new_fields, &inst->s1, sizeof inst->s1);
field_push(&new_fields, &inst->c1, sizeof inst->c1);
return new_fields;
}
Now you can use this Fields structure with general-purpose functions to read and write members of any struct, like so:
void write_fields(FILE* file, struct Fields* fields)
{
int j=0;
for (; j < fields->num; ++j)
fwrite(fields->ptrs[j], fields->sizes[j], 1, file);
}
This is generally a bit easier to work with than some functional for_each_field kind of approach accepting a callback.
Now all you have to worry about when you create some new struct, S, is to define a single function to output struct Fields from an instance to then enable all those general functions you wrote that work with struct Fields to now work with this new S type automatically.
A: Many compilers accept a command line parameter which means "pack structures". In addition, many accept a pragma:
#pragma pack(1)
where 1 means byte alignment, 2 means 16-bit word alignment, 4 means 32-bit word alignment, etc.
A: To make your solution platform independent, you can create a function that writes each field of the struct one at a time, and then call the function to write as many of the structs as needed.
int writeStruct(struct s* obj, size_t count, FILE* file)
{
size_t i = 0;
for ( ; i < count; ++i )
{
// Make sure to add error checking code.
fwrite(&(obj[i].i1), sizeof(obj[i].i1), 1, file);
fwrite(&(obj[i].s1), sizeof(obj[i].s1), 1, file);
fwrite(&(obj[i].c1), sizeof(obj[i].c1), 1, file);
}
// Return the number of structs written to file successfully.
return i;
}
Usage:
struct s example[2];
writeStruct(s, 2, file); | unknown | |
d19005 | test | The TryParse method allows you to test whether something is parseable. If you try Parse as in the first instance with an invalid int, you'll get an exception while in the TryParse, it returns a boolean letting you know whether the parse succeeded or not.
As a footnote, passing in null to most TryParse methods will throw an exception.
A: TryParse and the Exception Tax
Parse throws an exception if the conversion from a string to the specified datatype fails, whereas TryParse explicitly avoids throwing an exception.
A: If the string can not be converted to an integer, then
*
*int.Parse() will throw an exception
*int.TryParse() will return false (but not throw an exception)
A: Parse throws an exception if it cannot parse the value, whereas TryParse returns a bool indicating whether it succeeded.
TryParse does not just try/catch internally - the whole point of it is that it is implemented without exceptions so that it is fast. In fact the way it is most likely implemented is that internally the Parse method will call TryParse and then throw an exception if it returns false.
In a nutshell, use Parse if you are sure the value will be valid; otherwise use TryParse.
A: TryParse does not return the value, it returns a status code to indicate whether the parse succeeded (and doesn't throw an exception).
A: For the record, I am testing two codes: That simply try to convert from a string to a number and if it fail then assign number to zero.
if (!Int32.TryParse(txt,out tmpint)) {
tmpint = 0;
}
and:
try {
tmpint = Convert.ToInt32(txt);
} catch (Exception) {
tmpint = 0;
}
For c#, the best option is to use tryparse because try&Catch alternative thrown the exception
A first chance exception of type 'System.FormatException' occurred in mscorlib.dll
That it is painful slow and undesirable, however, the code does not stop unless Debug's exception are settled for stop with it.
A: I know its a very old post but thought of sharing few more details on Parse vs TryParse.
I had a scenario where DateTime needs to be converted to String and if datevalue null or string.empty we were facing an exception. In order to overcome this, we have replaced Parse with TryParse and will get default date.
Old Code:
dTest[i].StartDate = DateTime.Parse(StartDate).ToString("MM/dd/yyyy");
dTest[i].EndDate = DateTime.Parse(EndDate).ToString("MM/dd/yyyy");
New Code:
DateTime startDate = default(DateTime);
DateTime endDate=default(DateTime);
DateTime.TryParse(dPolicyPaidHistories[i].StartDate, out startDate);
DateTime.TryParse(dPolicyPaidHistories[i].EndDate, out endDate);
Have to declare another variable and used as Out for TryParse.
A: double.Parse("-"); raises an exception, while
double.TryParse("-", out parsed); parses to 0
so I guess TryParse does more complex conversions. | unknown | |

d19007 | test | It does not appear so. From here (emphasis mine):
For 35mm digital capture, we strongly recommend use of a professional-quality digital SLR using RAW or uncompressed TIFF format.
RAW or uncompressed TIFF images will tend to be very large, which could make uploading them via an API problematic. Instead, contributors would use the upload portal to supply content to Getty images.
Further, your images must go through a submission process, which would suggest the API could not be used.
Getty Images do have a Flickr collection that anyone can submit to, though once again there is submission process. | unknown | |
d19008 | test | First check whether your GPS is on in your device. You can use CLLocationManager to get your current location.
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
//Get your current location here
}
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error{

Use these methods to get the location.
A: I am not sure what the question is, but I think you have an IP address and you want to know which location is associated with it, right ? If so, you're out of luck. There are some databases to map these, but they can only tell you where the owner of the IP is located... and that is your ISP, not you (the customer).
On iOS, there's Core Location, doesn't that work for you ?
A: I am using the same, and it works fine when I am outside of my house, but in case I am inside the house or in basement it doesn't get the current location.
I am saying while using the IP address we can get the location so we will have a current location and then we can get the longitude and latitude of a particular location using g. | unknown | |
d19009 | test | Why not to join two tables, master one with id,type,name fields and nested with id,master_id,lang,value. For the given example that will be looking like:
ID TYPE NAME
1 text question
ID MASTER_ID LANG TRANSLATION
1 1 en question
2 1 nl vraag
The translation set for one language is given by SQL query:
SELECT * FROM `nested` WHERE `lang` = 'nl'
-- vraag
-- .....
The translation for the given term (e.g. question, having id=1):
SELECT * FROM `nested` WHERE `master_id` = 1 AND `lang` = 'nl'
-- vraag
A: The downside of the second idea is that for every new language you want to add you have to change your database structure (following code changes to reflect that structure change) whereas the first only needs new rows (which keeps the same structure).
another plus for the first idea is that you really only need the space/memory for translations you add to the database. in the second approach you could have lots of empty fields in case you won't translate all texts.
a way to do it could be (an addition to the answer above from @mudasobwa):
Master Table:
| id | type | master_name |
|----+------+-------------|
|853 | text | question |
|854 | text | answer |
Language Table:
| id | language_name |
|----+---------------|
| 1 | english |
| 2 | german |
Translation Table:
| id | master_id | language_id | translation |
|----+-----------+-------------+--------------------|
| 1 | 853 | 1 | question |
| 1 | 854 | 2 | Frage |
| 2 | 853 | 1 | answer |
| 2 | 854 | 2 | Antwort |
So if you have another language, add it to the language table and add the translations for your master texts for that language.
Adding indexes to the ids will help speeding up queries for the texts.
A: Second way is much better:
*
*Keeps less place in Database.
*Loads faster.
*Easy to edit. | unknown | |

}
the length of the loop changes when you scroll down so it gets all the rows in the table
A: This will not scroll down the page but take all the links in the web table into the list and click on the link which you need.
A: public void ClickLink(string link)
{
//scroll to table.
Actions action = new Actions(driver);
action.MoveToElement(driver.FindElement(By.Id("tableID"));
//get elements in list
List<WebElement> req = driver.findElements(By

//Click the required link.
foreach(IWebElement element in req)

string linkName = element.text;

d19013 | test | As it stands, there isn't much to choose between them. However, the @classmethod has one major plus point; it is available to subclasses of MyClass. This is far more Pythonic than having separate functions for each type of object you might instantiate in a list.
A: I would argue that the first method would be better (list comprehension) since you will always be initializing the data from a list. This makes things explicit. | unknown | |
d19014 | test | As I understand it you should and can avoid custom getters and setters and then you can leave core data to do it's thing and not worry about retain/release.
As for reducing memory overhead you can ask core data to turn your object to fault using this method: refreshObject:mergeChanges:
Check out the Apple documentation here: http://gemma.apple.com/mac/library/documentation/Cocoa/Conceptual/CoreData/index.html. It's all there and hopefully I've been able to give you the right terms to look for.
Hope that's some help.
A: If your setters are retaining the managed objects then you need to release them to match the retain/release. However you may not need to retain the managed objects depending on how the application is designed.
Without seeing all of the code it is difficult to give solid advice but you can use the analyzer to check for leaks, use instruments to make sure your memory is not increasing out of control, etc. And last but not least you can turn off retains, switch them to assigns and see if it crashes. Since the NSManagedObjectContext will retain the objects there is a fair chance that your views do not need to retain the NSManagedObject instances at all.
A: Yes, you need to release your representedGrid and representedCell properties in your dealloc method. If you didn't, the retain/release methods would not be balanced- your setter would be retaining the object, and with no corresponding release, the object will never be deallocated.
When written properly, a retain setter will release its old value and retain the new value. So there is no need to release the old grid when setting gridView.representedGrid.
Why are you writing your own setters, out of curiosity? | unknown | |

d19020 | test | Yes, at every thirteenth line you'd have the information of an employee.
However, instead of using twelve different lists, you can use a dictionary of lists, so that you wouldn't have to worry about the number of employees.
And you can either use a parameter on the number of lines directed to each employee.
You could do the following:
infile = open("file.txt", "rt")
employee = dict()
name = infile.readline().strip()
while name:
employee[name] = list()
for i in xrange(1, 12):
val = float(infile.readline().strip())
employee[name].append(val)
name = infile.readline().strip()
Some ways to access dictionary entries:
for name, months in employee.items():
print name
print months
for name in employee.keys():
print name
print employee[name]
for months in employee.values():
print months
for name, months in (employee.keys(), employee.values()):
print name
print months
The entire process goes as follows:
infile = open("file.txt", "rt")
employee = dict()
name = infile.readline().strip()
while name:
val = 0.0
for i in xrange(1, 12):
val += float(infile.readline().strip())
employee[name] = val
print ">>> Employee:", name, " -- salary:", str(employee[name])
name = infile.readline().strip()
Sorry for being round the bush, somehow (:
A: Here is option.
Not good, but still brute option.
summed = 0
with open("file.txt", "rt") as f:
print f.readline() # We print first line (first man)
for line in f:
# then we suppose every line is float.
try:
# convert to float
value = float(line.strip())
# add to sum
summed += value
# If it does not convert, then it is next person
except ValueError:
# print sum for previous person
print summed
# print new name
print line
# reset sum
summed = 0
# on end of file there is no errors, so we print lst result
print summed
since you need more flexibility, there is another option:
data = {} # dict: list of all values for person by person name
with open("file.txt", "rt") as f:
data_key = f.readline() # We remember first line (first man)
data[data_key] = [] # empty list of values
for line in f:
# then we suppose every line is float.
try:
# convert to float
value = float(line.strip())
# add to data
data[data_key].append(value)
# If it does not convert, then it is next person
except ValueError:
# next person's name
data_key = line
# new list
data[data_key] = []

for employee, stats in data.iteritems():
if sum(stats) > 7000:
print employee + " done 7000 in total sales! need 2% bonus"
A: I would not create 7 different arrays. I would create some sort of data structure to hold all the relevant information for one employee in one data type (this is python, but surely you can create data structures in python as well).
Then, as you process the data for each employee, all you have to do is iterate over one array of employee data elements. That way, it's much easier to keep track of the indices of the data (or maybe even eliminates the need to!).
This is especially helpful if you want to sort the data somehow. That way, you'd only have to sort one array instead of 7. | unknown | |
d19021 | test | You can achieve that by:
window?.toolbar?.showsBaselineSeparator = false | unknown | |
d19022 | test | You have issue with this code:
v_emp_first_name := select first_name from us_employees where email = '[email protected]';
You can not use the assignment operator against the query as you have used.
Replace this assignment := with INTO as follows:
select first_name INTO v_emp_first_name from us_employees where email = '[email protected]';
A: The short answer is NO. You can't assign the output of a scalar query to a variable. The proper syntax for your "assignment" is the one you are already aware of.
I am sure that you will then ask WHY. Why did Oracle choose that "weird" syntax for assignment, and not the simpler one you tried?
The answer is that in more general cases a select statement may return multiple columns, not just one; and the values from multiple columns can be "assigned" to multiple variables (local to the PL/SQL block) simultaneously. Which, by the way, is the more common usage - people extract one "record" at a time, rather than a single value. So, how would you re-write the "select into" operation as an "assignment" (or multiple "assignments")? There is no natural way to do that.
You may ask why Oracle doesn't allow "your" assignment syntax, in the case of a single column selected, in addition to the select into syntax (which is needed for multi-column rows anyway). The answer is that would be wasteful. We already have a syntax - that we need for more general cases anyway; we don't need one more.
You might say that we could put all the receiving local variables into a record type, and do a single assignment (to a record) even for general "rows" returned by a select. Alas, SQL statements return rows, not records; rows are a SQL concept, and specifically they are not a data type. Perhaps Oracle could do further development along those lines (to add functionality that doesn't exist today), but why bother - they already have a perfectly fine syntax for what you need, and you already know what that syntax is - without needing to define a record type to hold all your local variables, then define a "record type" for rows coming from a SQL select statement, then ..... | unknown | |

*You should have .section .text before .global _start so that _start ends up in the .text section
*Add -g to get debug infomation
Unfortunately, adding -g to a .c compilation would be fine. But, it doesn't work too well for a .s file
Here's a simple C program, similar to yours:
int value1;
short value2;
unsigned char value3;
We can compile this with -S to get a .s file. We can do this with and without -g. Without -g the .s file is 7 lines. Adding -g increases this to 150 lines.
The debug information has to be added with special asm directives (e.g. .loc and .section .debug_info,"",@progbits).
Then, gdb has enough information to allow p (or x) to work.
To get p to work without debug information, we have to cast the values to the correct type. For example, in your program:
p (int) value1
p (short) value2
p (char) value3
Here is the .s output for the sample .c file without -g:
.file "short.c"
.text
.comm value1,4,4
.comm value2,2,2
.comm value3,1,1
.ident "GCC: (GNU) 8.3.1 20190223 (Red Hat 8.3.1-2)"
.section .note.GNU-stack,"",@progbits

d19024 | test | I don't think that this is achievable via memoization, you need a cache instead from guava. It has methods that explicitly invalidate a key. So you would need a database trigger/listener that catches the event of when some entry changes and when that happens call:
Cache.invalidate(key)
and then
cache.put(key, value) | unknown | |
d19025 | test | We were able to create our own test data by using the 'Rest-Client’ gem (to call endpoints) and Cucumber hooks (used to determine when to generate test data).
See below example of how we created new accounts/customers by using the Rest-Client gem, cucumber hooks, a data manager class and a factory module. Here's a link with a bit more info on how it works.
AccountDataManager.rb
require 'rest-client'
require_relative '../factory/account'
class AccountDataManager
include Account
def create
current_time = Time.now.to_i
username = 'test_acc_' + current_time.to_s
password = 'password1'
url = 'http://yourURLhere.com/account/new'
request_body = manufacture_account(username, password)
response = RestClient.post url, request_body.to_json, {:content_type => 'application/json', :accept => 'application/json'}
if response.code != 200
fail(msg ="POST failed. Response status code was: '#{response.code}'")
end
response_body = JSON.parse(response
clientId = response_body['Account']['ClientId']
# return a hash of account details
account_details = {
username: username
password: password,
clientId: clientId
}
end
end
Account.rb
The below factory manufactures the request's body.
module Account
def manufacture_account(username, password)
payload = {
address:{
:Address1 => '2 Main St',
:Address2 => '',
:Suburb => 'Sydney',
:CountryCode => 8
},
personal:{
:Title => 'Mr',
:Firstname => 'John',
:Surname => 'Doe',
:UserName => "#{username}",
:Password => "#{password}",
:Mobile => '0123456789',
:Email => "#{username}@yopmail.com",
:DOB => '1990-12-31 00:00:00'
}
}
end
end
Hook.rb
You should add your hook.rb file to a shared directory and then add a reference to it into your env.rb file (we added our hook file to the "/features/support" directory).
require_relative '../data_manager/data_manager_account'
Before() do
$first_time_setup ||= false
unless $first_time_setup
$first_time_setup = true
# call the data managers needed to create test data before
# any of your calabash scenarios start
end
end
Before('@login') do
# declare global variable that can be accessed by step_definition files
$account_details = AccountDataManager.new.create
end
at_exit do
# call the data managers to clean up test data
end
Login_steps.rb
The final piece of the jigsaw is to get your calabash scenarios to consume the test data your've just generated. To solve this problem we declared a global variable ($account_details) in our hook.rb file and referenced it in our step_definition file.
Given(/^I log in with newly created customer$/) do
@current_page = @current_page.touch_login_button
unless @current_page.is_a?(LoginPage)
raise "Expected Login page, but found #{@current_page}"
end
# use global variable declared in hook.rb
@current_page = @current_page.login($account_details)
unless @current_page.is_a?(HomePage)
raise "Expected Home page, but found #{@current_page}"
end
end
A: I haven't gotten into using any fixture data libraries myself, however I've had luck just using simple models, like the following for a User.
class User
@validUser = "[email protected]"
@validPass = "123"
@invalidUser = "[email protected]"
@invalidPass = "foobar"
def initialize(username, password)
@username = username
@password = password
end
def username
@username
end
def password
@password
end
def self.getValidUser
return new(@validUser, @validPass)
end
def self.getInvalidUser
return new(@invalidUser, @invalidPass)
end
end
Let's say I have the following feature:
Scenario: Successful login
When I enter valid credentials into the login form
Then I should see a logout button
Then when I need a valid user, it's as easy as:
When(/^I enter valid credentials into the login form$/) do
user = User.getValidUser
enterCredentials(user)
end
And you can obviously replicate this model structure for anything than needs to hold a simple amount of information. Again, I can't speak for any fixture libraries as I haven't utilized those.
However, to your other question regarding the non-dependence of Scenario A on Scenario B - this is true, but this does not mean you can't string together step definitions to achieve your goals. Let's say the test above was simply used to validate that I can successfully log in to the application with a valid user - all is well, the user is logged in, and everyone's happy. But what happens when I need to test the profile page of a user? Well I obviously need to login, but I don't need that to be explicitly stated in my feature file, I can create a step definition that chains together other step definitions:
Scenario: Validate behavior of user profile page
Given I'm on my profile page
Then I should see a selfie
Given(/^I'm on my profile page$/) do
step "I enter valid credentials into the login form"
navigateToProfilePage()
end
This is a quick example, but hopefully you're seeing that you can indeed chain together step definitions without having scenarios themselves being depending on one another. Such a bad style of cucumber would be such that you log in to the application with Scenario "Login Successful" but then NEVER log the user out, and simply proceed with Scenario "Validate behavior of profile" which just navigates to the profile page without first logging back in. I hope I wasn't too far off from your original request!

d19026 | test | There is no linux-aarch64 version of pytorch on the default conda channel, see here
This is of course package specific. E.g. there is a linux-aarch64 version of beautifulsoup4 which is why you wre able to install it without an issue.
You can try to install from a different channel that claims to provide a pytorch for aarch64, e.g.
conda install -c kumatea pytorch | unknown | |
d19027 | test | When a requested entity is not found you should use 404 Not Found. Period. If your server deploy failed, clients should get a 5xx error, not a 4xx error.
You shouldn't design your application around your infrastructure shortcomings. If you need circumvent those shortcomings, you should do it in ways that are decoupled from your application, like middlewares, proxies, etc. | unknown | |
d19028 | test | Here is a very small program that performs an Ordered bulkWrite using Spring. You can change to unordered by changing the enum value on BulkOperations.BulkMode. This program will insert 3 records, then delete one, then update one. Because of the filter predicates in the later bulk commands I had to go with an ordered update. If you are only inserting you could easily get away with a faster unordered bulk command.
Main.java
package com.example.accessingdatamongodb;
import com.mongodb.bulk.BulkWriteResult;

@SpringBootApplication
public class Main implements CommandLineRunner {
@Autowired
private MongoOperations mongoTemplate;
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
@Override
public void run(String... args) throws Exception {
// CLEAR THE COLLECTION
mongoTemplate.remove(new Query(), Customer.class);
BulkOperations bulkOps = mongoTemplate.bulkOps(BulkOperations.BulkMode.ORDERED, Customer.class);
for (Integer i = 0; i < 3; i++)
{
Customer customer = new Customer();
customer.firstName = "Barry";
customer.id = i.toString();
bulkOps.insert(customer);
}
bulkOps.remove(new Query().addCriteria(new Criteria("i").is(1)));
bulkOps.updateOne(new Query().addCriteria(new Criteria("i").is(2)), new Update().set("name", "Barry"));
BulkWriteResult results = bulkOps.execute();
}
}

d19031 | test | Form onSubmit handler
To answer your immediate question, what's happening is input type submit in Angular calls the onSubmit method of the form (instead of submitting the form like in plain HTML). And because you don't have a handler for onSubmit in your class, nothing is happening.
For a quick test, follow this link to create a simple onSubmit handler method to test that your submit button works.
Here's a Stackblitz example which logs to console when you click the submit button: https://stackblitz.com/edit/angular-uy481f
File upload
To make file upload work, you would need to make a few things. This touches the component class, creating a new service and injecting it, and updating your form to bind it to the class.
*
*Create a proper Angular form. Here's an example.
*Create a method that will handle the onSubmit() of the form.
*Create a service that will handle Http calls to upload files.
*Inject the service into your class, and call the file upload method of that class.
As you can see, there's a lot involved in making this work unlike having a simple post form in the template. As such, it will be too much for a single answer.
But hopefully, the initial paragraph answered your question and the rest of the answer pointed you in the right direction. | unknown | |
d19032 | test | jQuery selectors return an Array object, objects cannot be deemed equal unless they are derived from each other.
i.e.
var a = []
var b = []
console.log(a==b); //would output false
If you changed you code to select the item in the array you would get the actual DOM node

Unlike last time I can't use quotation marks or other such character. I have to delete the whole line. One thing I thought about was to do something like this:
$html = preg_replace('/<a href=".*?(alt=""/>)/', '', $html);
I thought that using the above code would find the last portion in this segment and replace everything inside but it replaces nothing. Please suggest what should I do?
After running above line of code the output should be nothing. It should remove all this code block.
A: <a\s+href.*(alt="[^"]*")?>
or without quotation mark :
<a\s+href.*(alt="[^"]*"){0,1}>
We match everything that starts by <a, is followed by at least one space, then by any character until the character >, before which you may have zero or one iteration of the string alt="" containing anything but a ". | unknown | |
d19034 | test | Here:
Item firstItem = new Item(values[0]);
You are creating a new Item with an item pointer as its argument. This is the same as:
Item firstItem(new Item(values[0]));
And it should be:
Item *firstItem = new Item(values[0]); | unknown | |
d19035 | test | Replace
container.internalList.Add(item);
by
Dispatcher.BeginInvoke(new Action(() => container.internalList.Add(item)));
This way the Add is executed on the Dispatcher thread.
A: You can just get your data from a background thread as a List and then cast this list to an ObservableCollection as follows
List<SomeViewModel> someViewModelList = await GetYourDataAsListAsync();
ObservableCollection<SomeViewModel> Resources = new TypedListObservableCollection<SomeViewModel>(someViewModelList);
I hope this helps.
A: Make sure that you set the properties of UI objects on the UI thread:
Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Normal, (Action)delegate()
{
MyDataGrid.ItemsSource = container.internalList;
});
This will add the code within the curly braces onto the work items queue of the UI thread Dispatcher.
A: The problem is not in the Collection on your class but in the Control that is binding to this collection from UI Thread.
There is something new in WPF 4.5:
http://www.jonathanantoine.com/2011/09/24/wpf-4-5-part-7-accessing-collections-on-non-ui-threads/
//Creates the lock object somewhere
private static object _lock = new object();
//Enable the cross acces to this collection elsewhere
BindingOperations.EnableCollectionSynchronization(_persons, _lock);

d19037 | test | Eventually realized what the issue was with this. The change necessary to get this to work was to make these changes to the "Player" class...
public class Player {
/* other properties */
List<Picks> PickList { get; set; }
}
The issue was occurring because RestSharp was confused because the Property's name ("Picks") was the same as the Object Type ("Picks") that it was trying to deserialize. | unknown | |
d19038 | test | <div ng-class="{'currPeriod': day.current, 'notCurrPeriod': !day.current}">
{{day.date | date:"d"}}
</div>
ng-class doesn't work this way, use the object syntax to acheive what you want, or you can either set a default style when the day isn't in the current period, and apply the class when it is, it would shorten your ng-class statement | unknown | |
d19039 | test | It depends on what you want to do with birth.month later. If you have no intention of changing it, then the first is better (quicker, no memory cleanup requirement required, and each Date_t object shares the same data). But if that is the case, I would change the definition of month to const char *. In fact, any attempt to write to *birth.month will cause undefined behaviour.
The second approach will cause a memory leak unless you remember to free(birth.month) before birth goes out of scope.
A: You're correct, the second variant is the "good" one.
Here's the difference:
With 1, birth->month ends up pointing to the string literal "Nov". It is an error to try to modify the contents of birth->month in this case, and so birth->month should really be a const char* (many modern compilers will warn about the assignment for this reason).
With 2, birth->month ends up pointing to an allocated block of memory whose contents are "Nov". You are then free to modify the contents of birth->month, and the type char* is accurate. The caveat is that you are also now required to free(birth->month) in order to release this memory when you are done with it.
The reason that 2 is the correct way to do it in general, even though 1 seems simpler in this case, is that 1 in general is misleading. In C, there is no string type (just sequences of characters), and so there is no assignment operation defined on strings. For two char*s, s1 and s2, s1 = s2 does not change the string value pointed to by s1 to be the same as s2, it makes s1 point at exactly the same string as s2. This means that any change to s1 will affect the contents of s2, and vice-versa. Also, you now need to be careful when deallocating that string, since free(s1); free(s2); will double-free and cause an error.
That said, if in your program birth->month will only ever be one of several constant strings ("Jan", "Feb", etc.) variant 1 is acceptable, however you should change the type of birth->month to const char* for clarity and correctness.
A: Neither is correct. Everyone's missing the fact that this structure is inherently broken. Month should be an integer ranging from 1 to 12, used as an index into a static const string array when you need to print the month as a string.
A: I suggest either:
const char* month;
...
birth->month = "Nov";
or:
char month[4];
...
strcpy(birth->month, "Nov");
avoiding the memory allocation altogether.
A: With option 1 you never allocate memory to store "Nov", which is okay because it's a static string. A fixed amount of memory was allocated for it automatically. This will be fine so long as it's a string that appears literally in the source and you never try to modify it. If you wanted to read a value in from the user, or from a file, then you'd need to allocate first.
A: In the first case your cannot do something like birth->month[i]= 'c'. In other words you cannot modify the string literal "Mov" pointed to by birth->month because it is stored in the read only section of memory.
In the second case you can modify the contents of p->month because "Mov" resides on the heap. Also you need to deallocate the allocated memory using free in this case.
A: Seperate to your question; why is struct Date typedefed? it has a type already - "struct Date".
You can use an incomplete type if you want to hide the structure decleration.
In my experience, people seem to typedef because they think they should - without actually thinking about the effect of doing so.
A: For this example, it doesn't matter too much. If you have a lot of Date_t variables (in, say, an in-memory database), the first methow will lead to less memory usage over-all, with the gotcha that you should not, under any circumstances, change any of the characters in the strings, as all "Nov" strings would be "the same" string (a pointer to the same 4 chars).
So, to an extent, both variants are good, but the best one would depend on expected usage pattern(s). | unknown | |

And then manipulate the objects on the returned results. by looping through each and setting:

d19043 | test | in this excerpt of your code:
...(

you are calling the result of that conditional as if it were a function. The code is very hard to read, but I see no signs that it returns a function of no arguments.
PS. please try to use idiomatic style, in particular this code would be much more readable with let bindings and line breaks.
the trivial fix is to add a call to println (or some other innocuous function) at that hanging open brace:
...(println
(if (= (get array (int...
Better is to actually make readable and idiomatic Clojure code:
(defn binary-search
"searches for a single element in a sorted array in logartihmic time"
([array start end element]
(let [middle_exact (+ (/ (- end start) 2) start)
middle (int middle_exact)
middle-elt (get array (int middle))]

:otherwise
(recur array (int (Math/ceil (+ start (/ middle_exact 2)))) end element))))
([array element]
(println "starting binary search....")
(binary-search array 0 (dec (count array)) element)))

d19044 | test | For the case that someone has the same problem (like me some hours ago), there is a still better solution:
Let "bootloader.out" be the bootloader-binary. Then we can generate with
nm -g bootloader.out | grep '^[0-9,a-e]\{8\} T' | awk '{printf "PROVIDE(%s = 0x%s);\n",$3,$1}' > bootloader.inc
a file that we can include in the linker script of the application with
INCLUDE bootloader.inc
The linker knows now the addresses of all bootloader-functions and we can link against it without to have the actual function code in the application. All what we need there is a declaration for every bootloader-function which we want to execute.
A: The way I found around this was to use function pointers, i.e.
void (*formatted_write)( int a, char * b, struct mystruct c );
then, in the code somewhere at boot set the address of this function, i.e.
formatted_write = 0xa0000;
you can then call your function using the normal convention.
Additionally, you can use the -Wl,--just-symbols=symbols.txt flag when compiling. You can set the address of your symbols as follows:
formatted_write = 0xa0000; | unknown | |
d19045 | test | In case anyone discovered this post, I managed to finish it myself. I used this plugin but had to manually rewrite it quite a lot, changing the conditions on when to call the authentication endpoint (call it on init rather than on url route parameter change), had to write new code for calling reshresh token endpoint and logout endpoint and all sorts of other stuff.
Sadly, i can't publish the newly edited plugin, since my client wouldn't allow it. The takeaway from this is that if you want SSO against an external identity provider in such a way that without being logged in through your SSO you can't view the page, it's difficult and you'd either have to pay money for an expensive plugin or extend an existing plugin, spending days figuring out how to do it.
A: Was working on something similar way back. It is true that for most of the plugins we need to pay. I too have tried miniorange and the other plugin you have mentioned. The use case which you are referring to, I have done some manual changes from my side to achieve it and never got the solution I was looking for. After some research, I found out that this Page and Post restriction plugin by miniorange itself along with the SSO plugin can be used to restrict all access to users who are not logged in if I am not wrong about it, you can give it a try yourself. | unknown | |
d19046 | test | Generally speaking, the server-side upgrade does not affect your client. The client is still based on Subversion 1.6. You have to upgrade the client to benefit from the client-side improvements.

d19047 | test | As an alternative to using the :substitute command (the usage of

d19049 | test | Solution
Change
virtual ~hittable() = 0;
into
virtual ~hittable() = default;
or
virtual ~hittable()
{
// does nothing
}
The destructor can remain pure virtual, but it must have a definition.
hittable::~hittable()
{
// does nothing
}
So what happened?
We can crush the given code down to the following example (Note I can't reproduce the missing vtable with this code or the given code, but regardless, the above will fix it)
Minimal example:
class hittable
{
public:
virtual ~hittable() = 0; // here we have a destructor,
// but there's no implementation
// so there is nothing for the
// destructors of derived classes
// to call
virtual bool hit() const = 0;
};
class sphere: public hittable
{
public:
bool hit() const;
};
bool sphere::hit() const
{
return false;
}
destructors call any base class destructors, and when shpere goes to call ~hittable, it finds that while ~hittableis declared, there is no implementation. Nothing to call. | unknown | |

Or, if your jobs are called job_1.sh to job_200.sh:

Or. if your jobs are named with discontiguous, random names but are all shell scripts named with .sh suffix in one directory:
parallel -j 10 ::: *.sh
There is a very good overview here. There are lots of questions and answers on Stack Overflow here.
A: Simply run them as background jobs:
for i in {1..10}; { ./script.sh & }
Adding more jobs if less than 10 are running:
while true; do
pids=($(jobs -pr))
((${#pids[@]}<10)) && ./script.sh &
done &> /dev/null
A: There are different ways to handle this:
*
*Launch them together as background tasks (1)
*Launch them in parallel (1)
*Use the crontab (2)
*Use at (3)
Explanations:
(1) You can launch the processes exactly when you like (by launching a command, click a button or whatever event you choose)
(2) The processes will be launched at the same time, every (working) day, periodically.
(3) You choose a time when the processes will be launched together once.

d19051 | test | You can call the procedure from a function just as you'd call any other PL/SQL block
CREATE OR REPLACE FUNCTION my_function
RETURN integer
IS
l_parameter VARCHAR2(100) := 'foo';
BEGIN
insert_into_table_a( l_parameter );
RETURN 1
END;
That being said, it doesn't make sense to call this procedure from a function. Procedures should manipulate data. Functions should return values. If you call a procedure that manipulates data from a function, you can no longer use that function in a SQL statement, which is one of the primary reasons to create a function in the first place. You also make managing security more complicated-- if you use functions and procedures properly, DBAs can give read-only users execute privileges on the functions without worrying that they'll be giving them the ability to manipulate data.
The procedure itself seems highly suspicious as well. A column named address_id in the address table should be the primary key and the name implies that it is a number. The same applies for the contact_id column in the contact table and the telephone_id column in the telephone table. The fact that you are inserting a string rather than a number and the fact that you are inserting the same value in the three tables implies that neither of these implications are actually true. That's going to be very confusing for whoever has to work with your system in the future. | unknown | |

A: Web scraping with Mojolicious is probably simplest way to do it in Perl nowadays

d19055 | test | PNG is a compressed image format, so the IDAT chunk(s) contain a zlib-compressed representation of the RGB pixels. Probably the easiest way for you to access the pixel data is to use a converter such as ImageMagick or GraphicsMagick to decompress the image into the Netpbm "PPM" format.
magick image.png image.ppm
or
gm convert image.png image.ppm
Then read the "image.ppm" in the same way you tried to read the PNG. Just skip over the short header, which in the case of your image is
P 6 \n 6 6 0 3 3 0 \n 2 5 5 \n
where "P6" is the magic number, 660 and 330 are the dimensions, and 255 is the image depth (maximum value for R,G,and B is 255, or 0xff). The remainder of the file is just the R,G,B values you were expecting. | unknown | |
d19056 | test | Suppose you've defined a component named"
ChildComponent.razor
<div>@ID.ToString()</div>
@code {
[Parameter]
public int ID { get; set; }
}
Which has a parameter property ID, provided by the parent component, like this:
ParentComponent.razor
@for (int i = 0; i < 10; i++)
{
<ChildComponent @ref="component" ID="i" />
}
@code
{
private ChildComponent component { set => components.Add(value); }
List<ChildComponent> components = new List<ChildComponent>();
protected override void OnInitialized()
{
foreach (var component in components)
{
Console.WriteLine(component.ID);
}
}
}
Now, you can identify the component by its ID. A simple and effective way, though you may do that in other ways.
Note: This is wrong:
<MyInput @onkeydown="KeyDown" @ref="NewInput"></MyInput>
because you assign the name of a method, the "KeyDown", to the @onkeydown compiler directive, which is only applicable to Html tags, not to component.
You can do something like this:
<MyInput ID="id" @ref="NewInput"></MyInput>
ID should be a parameter property defined in MyInput component, which is a child component, mind you. You also have to define an EventCallback which should be triggered from an event handler for the keydown event. In the cuurent case the EventCallback should return to the parent component, the ID of the child component in whose html tag, say an input html element, the keydown event occurs. I hope you succeed to get what I'm saying... if not, don't hesitate to ask questions.
UPDATE:
Note: I've added some code to my previous code sample to demonstrate how to return the ID of each ChildComponent when you hit the KeyDown button of an input Html element embedded in each child component. Additionally, my code also demonstrate how to return a reference to each component when its KeyDown event takes place:

d19061 | test | You might also try fixing your app so it always saves the same base date with the time (like '01/01/1900' or whatever) and then you do not have to do all these slow and inefficient date stripping operations every time you need to do a query.
Or as Joel said, truncate or strip off the date portion before you do the insert or update.
A: from d in dates
orderby d.TimeOfDay
select d;
or
dates.OrderBy(d => d.TimeOfDay);
Note: This will work as long as this is plain LINQ and not LINQ-to-SQL. If you're using LINQ-to-SQL to query your database, you'll need something that will translate to SQL.
A: Well, you can't really store a datetime without a date, but you could just store the total seconds as an double (using @florian's method).
You'd have to add a second method to convert this back to a date in your object, if you still need a date, such as:
public class BusinessObjectWithDate
{
private string _someOtherDbField = "";
private double _timeInMS = 0; // save this to the database
// sort by this? in sql or in code. You don't really need this
// property, since TimeWithDate actually saves the _timeInMS field
public double TimeInMS {
get { return _timeInMS; }
}
public DateTime TimeWithDate { // sort by this too, if you want
get { return (new DateTime(1900,1,1).AddMilliseconds(_timeInMS)); }
set { _timeInMS = value.TimeOfDay.TotalMilliseconds; }
}
}
var f = new BusinessObjectWithDate();
MessageBox.Show( f.TimeWithDate.ToString() ); // 1/1/1900 12:00:00 AM
f.TimeWithDate = DateTime.Now;
MessageBox.Show( f.TimeWithDate.ToString() ); // 1/1/1900 1:14:57 PM
You could also just store the real date time, but always overwrite with 1/1/1900 when the value gets set. This would also work in sql
public class BusinessObjectWithDate
{
private DateTime _msStoredInDate;
public DateTime TimeWithDate
{
get { return _msStoredInDate; }
set {
var ms = value.TimeOfDay.TotalMilliseconds;
_msStoredInDate = (new DateTime(1900, 1, 1).AddMilliseconds(ms));

d19065 | test | It seems your accuracy function is correct since you didn't post whole your code, I would suggest you calculate accuracy inside the session, so each time you can print the content of predictions and true labels and trace the execution.
Get predictions like predictions = sess.run(y, feed_dict={x: batchx, y_: batchy}) then print predictions by print predictions.eval(), then use plabel = tf.argmax(predictions, 1), again print plabel.eval(), also print batchy and print (tf.argmax(batchy)).eval()
Now you should know what's going wrong with each print statement.
A: For accuracy :
def evaluate(X_data, y_data):
num_examples = len(X_data)
total_accuracy = 0
sess = tf.get_default_session()
for offset in range(0, num_examples, BATCH_SIZE):
batch_x, batch_y = X_data[offset:offset+BATCH_SIZE], y_data[offset:offset+BATCH_SIZE]
accuracy = sess.run(accuracy_operation, feed_dict={x: batch_x, y: batch_y})
total_accuracy += (accuracy * len(batch_x))
return total_accuracy / num_examples
for getting the prediction :
prediction = sess.run(tf.argmax(logits, 1), feed_dict={x: train_data}) | unknown | |

d19068 | test | I'm assuming you're looking for number_format or its more advanced brother money_format. This will take care of the server-side for you.
As for the client-side, I would advise against making things change while the user's typing. Just let them type in the number how they want. Bonus points if you allow them to type in thousand separators (since you can just strip them out easily in PHP to get the number itself).
A: Try number_format
$english_format_number = number_format(floatval($total));
echo $english_format_number;
A: You need to use javascript for that, when user change the input value you need to call the function to format the value.
You have to something like this:
$("[name^='num']").change(function(){
var value = $(this).val();
$(this).val(money_format(format, value));
});
Here is the function for monet format :

d19070 | test | The simple answer is don't use autoCommit - it commits on a schedule.
Instead, let the container do the commits; using AckMode RECORD.
However you should still make your code idempotent - there is always a possibility of redelivery; it's just that the probability will be smaller with a more reliable commit strategy. | unknown | |
d19071 | test | So, according to your question and comments, you have code somewhere that creates a JLabel named topCaption, adds it to a JPanel called viewWindow, and you can see the label as a results.
So somewhere you have:
JLabel topCaption = new JLabel( you may have some stuff here );
Right after that, do this:
Font font = topCaption.getFont();
Map attributes = font.getAttributes();
attributes.put(TextAttribute.UNDERLINE, TextAttribute.UNDERLINE_ON);
topCaption.setFont(font.deriveFont(attributes));
Also, I might suggest you need to do more reading before you continue with this, as knowledge of what a Map is, etc. is pretty basic to most UI programming, and you're going to continue to have trouble like this without some fundamentals under your belt. | unknown | |

Mass Assignment
You may also use the create method to save a new model in a single line. The inserted model instance will be returned to you from the method. However, before doing so, you will need to specify either a fillable or guarded attribute on the model, as all Eloquent models protect against mass-assignment by default.
You need to make sure $fillable or $guarded is correctly set otherwise changes may not be persistant.

d19076 | test | If you add an onKeyPress event to the element in question, you can prevent the default action (form submission) by returning false from the function:
<input id="txt" type="text" onKeyPress="var key = event.keyCode || event.which; if (key == 13) return false;"></input>
Note that the which property of the keyboard event is deprecated, but you'll still want to check for it to support older user agents and/or Internet Exploder (reference).
If you don't want to use inline javascript (which is not recommended), you can instead attach an event. Also, it may be better to use the preventDefault (docs) method of the event object, as well as the stopPropagation method (docs) - the necessity for these methods this is highly dependent on what other events you have attached to the form or the elements:
var preventFormSubmit = function (event) {
var key = event.keyCode || event.which;
if (key != 13)
return;
if (event.stopPropagation) event.stopPropagation();
else event.cancelBubble = true; // deprecated, for older IE
if (event.preventDefault) event.preventDefault();
else event.returnValue = false; // deprecated, for older IE
return false;
};
var target = document.getElementById('txt');
if (typeof target.addEventListener == 'function')
target.addEventListener('keypress', preventFormSubmit, false);
else if (typeof target.attachEvent == 'function')
target.attachEvent('onkeypress', preventFormSubmit);
There are other approaches to use, such as attaching a more complex onSumit handler to the form itself - this may be more appropriate if you're going to be doing further manipulation of the form or data before submitting (or using AJAX to submit the form data).

d19077 | test | There are at least two ways to achieve same results. First one with namespaces. Second one - with static functions in classes.
With namespaces:
#include <stdio.h>

{
void add();
using GenericMath::dot;

namespace GenericMath

With classes:

class GenericMath
{
public:
static void add();
static void dot();
};
class ArmMath : public GenericMath
{
public:
static void add();
};

d19080 | test | I'll assume you have SQL Server 2008 or greater. You can do this all in one statement without any variables.
Instead of doing all the work to first get the variables and see if they don't match, you can easily do that in as part of where clause. As folks have said in the comments, you can have multiple rows as part of inserted and deleted. In order to make sure you're working with the same updated row, you need to match by the primary key.
In order to insert or update the row, I'm using a MERGE statement. The source of the merge is a union with the where clause above, the top table in the union has the older fahrer, and the bottom has the new farher. Just like your inner IFs, existing rows are matched on farher and dispodat, and inserted or updated appropriately.
One thing I noticed, is that in your example newfahrer and oldfahrer could be exactly the same, so that only one insert or update should occur (i.e. if only bzeit was different). The union should prevent duplicate data from trying to get inserted. I do believe merge will error if there was.
MERGE tbldispofahrer AS tgt
USING (
SELECT d.farher, d.dispodat, GETDATE() [laenderung]
INNER JOIN inserted i ON i.PrimaryKey = d.PrimaryKey
AND (i.fahrer <> d.fahrer OR i.beschreibk <> d.beschreik ... )

laenderung = GETDATE()

d19084 | test | It's virtually impossible to debug this without seeing the data.
The use quotes option requires that each field is surrounded by double quotes. Do not use this if your data does not contain these because the input process will import everything into the first field.
When you use comma as the delimiter, the observed behaviour is likely to be because there are additional commas contained in the data. This seems likely if the data is based on Twitter. This confuses the import because it is just looking for commas.
Generally, if you can get the input data changed, try to get it produced using a delimiter that cannot appear in the raw text data. Good examples would be | or tab. If you can get quotes around the fields, this will help because it allows delimiter characters to appear in the field.
Dates formats can be handled using the data format parameter but my advice is to import the date field as a polynominal and then convert it later to date using the Nominal to Date operator. This gives more control especially when the input data is not clean. | unknown | |

d19086 | test | One way to solve this is with jQuery and an additional control variable:
$( gui.domElement ).mouseenter(function(evt) {
enableRaycasting = false;
} );
$( gui.domElement ).mouseleave(function() {
enableRaycasting = true;
} );
You can then use enableRaycasting in order to determine if raycasting should happen.

d19088 | test | I had the error user lacks privilege or object not found while trying to create a table in an empty in-memory database.
I used spring.datasource.schema and the problem was that I missed a semicolon in my SQL file after the "CREATE TABLE"-Statement (which was followed by "CREATE INDEX").
A: As said by a previous response there is many possible causes. One of them is that the table isn't created because of syntax incompatibility. If specific DB vendor syntax or specific capability is used, HSQLDB will not recognize it. Then while the creation code is executed you could see that the table is not created for this syntax reason. For exemple if the entity is annoted with @Column(columnDefinition = "TEXT") the creation of the table will fail.
There is a work around which tell to HSQLDB to be in a compatible mode
for pgsl you should append your connection url with that
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_pgs=true"
and for mysql with
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_mys=true"
oracle
"spring.datasource.url=jdbc:hsqldb:mem:testdb;sql.syntax_ora=true"
note there is variant depending on your configuration
it could be hibernate.connection.url= or spring.datasource.url=
for those who don't use the hibernate schema creation but a SQL script you should use this kind of syntax in your script
SET DATABASE SQL SYNTAX ORA TRUE;
It will also fix issues due to vendor specific syntax in SQL request such as array_agg for posgresql
Nota bene : The the problem occurs very early when the code parse the model to create the schema and then is hidden in many lines of logs, then the unitTested code crash with a confusing and obscure exception "user lacks privilege or object not found error" which does not point the real problem at all. So make sure to read all the trace from the beginning and fix all possible issues
A: If you've tried all the other answers on this question, then it is most likely that you are facing a case-sensitivity issue.
HSQLDB is case-sensitive by default. If you don't specify the double quotes around the name of a schema or column or table, then it will by default convert that to uppercase. If your object has been created in uppercase, then you are in luck. If it is in lowercase, then you will have to surround your object name with double quotes.
For example:
CREATE MEMORY TABLE "t1"("product_id" INTEGER NOT NULL)
To select from this table you will have to use the following query
select "product_id" from "t1"
A: user lacks privilege or object not found can have multiple causes, the most obvious being you're accessing a table that does not exist. A less evident reason is that, when you run your code, the connection to a file database URL actually can create a DB. The scenario you're experiencing might be you've set up a DB using HSQL Database Manager, added tables and rows, but it's not this specific instance your Java code is using. You may want to check that you don't have multiple copies of these files: mydb.log, mydb.lck, mydb.properties, etc in your workspace. In the case your Java code did create those files, the location depends on how you run your program. In a Maven project run inside Netbeans for example, the files are stored alongside the pom.xml.
A: I had similar issue with the error 'org.hsqldb.HsqlException: user lacks privilege or object not found: DAYS_BETWEEN' turned out DAYS_BETWEEN is not recognized by hsqldb as a function. use DATEDIFF instead.
DATEDIFF ( <datetime value expr 1>, <datetime value expr 2> )
A: When running a HSWLDB server. for example your java config file has:
hsql.jdbc.url = jdbc:hsqldb:hsql://localhost:9005/YOURDB;sql.enforce_strict_size=true;hsqldb.tx=mvcc
check to make sure that your set a server.dbname.#. for example my server.properties file:
server.database.0=eventsdb
server.dbname.0=eventsdb
server.port=9005
A: I was inserting the data in hsql db using following script
INSERT INTO Greeting (text) VALUES ("Hello World");
I was getting issue related to the Hello World object not found and HSQL database user lacks privilege or object not found error
which I changed into the below script
INSERT INTO Greeting (text) VALUES ('Hello World');
And now it is working fine.
A: Add these two extra properties:
spring.jpa.hibernate.naming.implicit-strategy=
org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl
spring.jpa.hibernate.naming.physical-strategy=
org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
A: I bumped into kind of the same problem recently. We are running a grails application and someone inserted a SQL script into the BootStrap file (that's the entry point for grails). That script was supposed to be run only in the production environment, however because of bad logic it was running in test as well. So the error I got was:
User lacks privilege or object not found:
without any more clarification...
I just had to make sure the script was not run in the test environment and it fixed the problem for me, though it took me 3 hours to figure it out. I know it is very, very specific issue but still if I can save someone a couple of hours of code digging that would be great.
A: I was having the same mistake. In my case I was forgetting to put the apas in the strings.
I was doing String test = "inputTest";
The correct one is String test = "'inputTest'";
The error was occurring when I was trying to put something in the database
connection.createStatement.execute("INSERT INTO tableTest values(" + test +")";
In my case, just put the quotation marks ' to correct the error.
A: In my case the error occured because i did NOT put the TABLE_NAME into double quotes "TABLE_NAME" and had the oracle schema prefix.
Not working:
SELECT * FROM FOOSCHEMA.BAR_TABLE
Working:
SELECT * FROM "BAR_TABLE"
A: had this issue with concatenating variables in insert statement. this worked
// var1, var3, var4 are String variables
// var2 and var5 are Integer variables
result = statement.executeUpdate("INSERT INTO newTable VALUES ('"+var1+"',"+var2+",'"+var3+"','"+var4+"',"+var5 +")");
A: In my case the issue was caused by the absence (I'd commented it out by mistake) of the following line in persistence.xml:
<property name="hibernate.hbm2ddl.auto" value="update"/>
which prevented Hibernate from emitting the DDL to create the required schema elements...
(different Hibernate wrappers will have different mechanisms to specify properties; I'm using JPA here)
A: I had this error while trying to run my application without specifying the "Path" field in Intellij IDEA data source (database) properties. Everything else was configured correctly.
I was able to run scripts in IDEA database console and they executed correctly, but without giving a path to the IDEA, it was unable to identify where to connect, which caused errors.
A: You have to run the Database in server mode and connect.Otherwise it wont connect from external application and give error similar to user lacks privilege.
Also change the url of database in spring configuration file accordingly when running DB in server mode.
Sample command to run DB in server mode
$java -cp lib/hsqldb.jar org.hsqldb.server.Server --database.0 file:data/mydb --dbname.0 Test
Format of URL in configuration file
jdbc:hsqldb:hsql://localhost/Test
A: In my case, one of the columns had the name 'key' with the missing @Column(name = "key") annotation so that in the logs you could see the query that created the table but in fact it was not there. So be careful with column names
A: For what it's worth - I had this same problem. I had a column named 'TYPE', which I renamed to 'XTYPE' and a column named ORDER which I renamed to 'XORDER' and the problem went away.
A: Yet another reason could be a misspelt field name. If your actual table has an id column named albumid and you'd used album_id, then too this could occur.
As another anwer remarked, case differences in field names too need to be taken care of.
A: I faced the same issue and found there was more than one PersistenceUnit (ReadOnly and ReadWrite) , So the tables in HSQLDDB created using a schema from one persistence unit resulted in exception(HSQL database user lacks privilege or object not found error) being thrown when accessed from other persistence unit .It happens when tables are created from one session in JPA and accessed from another session
A: In my case the table MY_TABLE was in the schema SOME_SCHEMA. So calling select/insert etc. directly didn't work. To fix:
*
*add file schema.sql to the resources folder
*in this file add the line CREATE SCHEMA YOUR_SCHEMA_NAME; | unknown | |

d19093 | test | Looks like there are some problems with the embedded derby database. I'd try to completely redeploy ODE so that the database is extracted from the .war again.
A: You have to execute Eclipse or NetBeans as Administrator. | unknown | |
d19094 | test | Is there any reason why you are using both ng-if and ng-show? I think one of them should suffice. The ngIf directive removes or recreates a portion of the DOM tree based on an expression. If the expression assigned to ngIf evaluates to a false value then the element is removed from the DOM, otherwise a clone of the element is reinserted into the DOM.
A: Your code has ng-show="claim.claimToDealerCurrencyExchangeRate == null" which means the div will be visible when claim.claimToDealerCurrencyExchangeRate is null. As per your ask, your logic is wrong. Use ng-hide="claim.claimToDealerCurrencyExchangeRate == null" or ng-show="claim.claimToDealerCurrencyExchangeRate != null". But since you are already using ng-if, you should combine all the conditions within it, unless you absolutely want the DOM element to be toggled between visibility and non-visibility multiple times and not have it re-instantiated every time, use a combination of ng-if and ng-show.
Also, understand empty and null are two different things in JavaScript. For example, if value is a variable. Then value = "" is empty but not null. value = "null" is not null but a non-empty string. Set value = null explicitly then it is null. And in all cases value is not undefined. Check what exactly claim.claimToDealerCurrencyExchangeRate is being set and define your logic in ng-show appropriately. | unknown | |

d19096 | test | if you have some experience with resposive design and media queries, i would code it myself to avoid the thousands of lines of unnecessary code that comes with frameworks/libraries. bootstrap is great, but it also requires a bit of effort to master, and it would be a bit overkill for this one layout (if i understand you correctly).
if you just need this one layout, i would really recommend you do code it from scratch (personally i'd use something like jQuery and LESS). i hope i understood your question correctly, and sorry if this was not very hands-on.
to sum it up: in my opinion you're probably better off coding it yourself, but bootstrap and other frameworks will provide valuable insight and inspiration for how to do it. | unknown | |

d19099 | test | Q: I used the method *px = 8 first to change it
A: The value of both "x" and "*px" changed to "8", correct?
Q: but right after that I used x = 99, and it changed too
A: Cool. So now both "x" and "*px" are 99. This is what you expected, correct?
Q: so I do not know what is the difference between them.
In this example, they're both equivalent. They both accomplish exactly the same thing.
Why use pointers at all? Because the variable "x" is tied to a specific memory location: you can't change it.
The pointer "px", on the other hand, can be changed at runtime to point to DIFFERENT memory locations, if you needed to.
Why is that useful? There are many different reasons. For example:
*
*When you malloc() dynamic memory, the system gives you a pointer. You don't know or care where in memory it's located: you just use it.
*Pointers are frequently needed to traverse the elements in a linked list
*The ability to increment (++) and decrement (--) pointers simplifies many algorithms
*Etc. etc.
You might find these articles helpful:

*C - Pointers
*Pointer (computer programming)
A: Other answers explained what is happening, but in your question I also read you ask 'why' someone would want to use references instead of direct accessing of a memory address.
There are many reasons why anything is the way it is in computer science, but a few I think most people wouldn't argue that are helpful for a beginning theoretical understanding:
A lot of Computer Science as a discipline is efficient/optimal management of resources, in many cases computer memory, but I/O and CPU make up two other resources we manage to make 'good' software. You may recall that a simple computer can be thought of as a CPU, RAM, and Storage, connected by a "bus".
Up until relatively recently, most software wasn't being run on a machine with lots and lots of RAM. It was necessary that memory be managed for performance purposes, and though we have access to higher memory machines today - memory must still be managed!
We manage that in more recently created languages with abstraction - or in this context, doing things for people when we know with a high degree of certainty what they are trying to do. We call languages where much of resource management is abstracted and simplified as "high-level" languages. You are "talking" to the machine with your code at a high level of control relative to machine code (you can think of that as the ones and zeros of binary).
TLDR; Memory is finite, and pointers generally take up less space than the data they point to, allowing for an efficiency in address space utilization. It also allows for many other neat things, like virtualized address spaces. | unknown | |
d19100 | test | I have spent the last couple hours trying to diagnose this issue and came up with a solution however the code changes quite abit. Basically the first thing you can do is actually set the property "location" to be required. You will notice that once you set it as required that the Graph API is failing due to a required property missing.
This is a good sign, it means that something is not quite right with the submission. After digging around and manually creating objects in the Object Browser I came up with a solution. Now it is worth noting that I am using dnyamic ExpandoObjects instead of dictionaries but the concept is the same. Review the commented code
//create our location object
dynamic locationData = new ExpandoObject();
locationData.title = "sample app testing " + DateTime.Now.ToString();
//create our geolocation object
dynamic geoData = new ExpandoObject();
geoData.latitude = 37.416382;
geoData.longitude = -122.152659;
geoData.altitude = 42; //<-- important altitude figure
//create our geo data item container and add the geoData object to the geolocation property
dynamic geoDataItem = new ExpandoObject();
geoDataItem.geolocation = geoData;
//set the data property of our location data to the geo data item container
locationData.data = geoDataItem;
//create our root object setting the location property to the location data object
dynamic objItem = new ExpandoObject();
objItem.location = locationData;
var response = context.Client.Post("me/<my_app_name>:<app_action>", objItem);
Really all we are doing is creating a simple structure using the expando object. Where I personally got stuck what not understanding how the complete GeoPoint operates. If you notice we have to create 2 containers.
One container so we can set the geolocation property on the data property of the location object.
The final structure resembles
--- MyStory
--- location
--- title : 'Sample app testing....'
--- data
--- geolocation
--- latitude : 37.416...
--- longitude : -122.1526...
--- altitude : 42
This does seem rather complex but here is a final output preview. | unknown |
