d1401 | train | The container #cboxWrapper has overflow: hidden; set (near the top of your included CSS); if you add overflow: visible; to that selector, your moved X button should be visible.
I wouldn't recommend changing the original overflow: hidden; declaration, since it involves other selectors, but just adding the the following:
#cboxWrapper {
overflow: visible;
} | unknown | |
d1402 | train | You seem to be looking for a conditional sum. The logic is to put a case expression within the aggregate function, like so:
select
sum(case when "2020" < 0 then "2020" else 0 end) result_2020,
sum(case when "2021" < 0 then "2021" else 0 end) result_2021
from mytable
It is quite unusal to have columns with all-digits names such as 2020, so I wonder whether what you are showing is your actual sample data or the results of an intermediate query (in which case, further optimizations may be possible).
Edit
The above answers the original version of the question. This answers the edited question:
You can use a case expression to turn positive numbers for date 2021 to 0:
select
fab,
date,
case when output > 0 and date = 2021
then 0
else output
end output
from mytbale
A: Say if you have a table like below
I think you are looking for something like this
SELECT id,
year,
(case when (a>0 and year = 2021) then 0 else a end) as a_filtered,
(case when (b>0 and year = 2021) then 0 else b end) as b_filtered
FROM `table_name`
WHERE 1
The output will be the following. | unknown | |
d1403 | train | It literally means that the the tuple class in Python doesn't have a method called to. Since you're trying to put your labels onto your device, just do labels = torch.tensor(labels).to(device).
If you don't want to do this, you can change the way the DataLoader works by making it return your labels as a PyTorch tensor rather than a tuple.
Edit
Since the labels seem to be strings, I would convert them to one-hot encoded vectors first:
>>> import torch
>>> labels_unique = set(labels)
>>> keys = {key: value for key, value in zip(labels_unique, range(len(labels_unique)))}
>>> labels_onehot = torch.zeros(size=(len(labels), len(keys)))
>>> for idx, label in enumerate(labels_onehot):
... labels_onehot[idx][keys[label]] = 1
...
>>> labels_onehot = labels.to(device)
I'm shooting a bit in the dark here because I don't know the details exactly, but yeah strings won't work with tensors. | unknown | |

d1406 | train | Looking at the documentation, you can do this to get more sessions:
$sessions = Tracker::sessions(60 * 24 * 365 ); // get sessions (visits) from the past 365 days

You can also use Query Builder to count the table directly:

d1407 | train | Try to get hold of the people from Google Developer relations here, in the relevant Google+ communities or on Google groups.
If it can bring you any comfort: paying the $150 does not help you much - we have the subscription.
A: If you have a second Google Apps domain, replicate the issue by switching domains and recreating the project from scratch. Then if the error occurs again, post that it occurs in 2 or more cloud.google.com accounts with separate domains. This should help show this is not a one off error and requires investigation.
If it does not occur in the second domain, save your data, delete your project and recreate with a different project name and number.

d1408 | train | So I managed to solve it, by finding the max index in the array.
I have commented the code, so it can help others. Thanks, all.
function myFunction() {
// Use sheet
var ss = SpreadsheetApp.getActiveSheet();
// Gmail query
var query = "label:support -label:trash -label:support-done -from:me";
// Search in Gmail, bind to array
var threads = GmailApp.search(query);
// Loop through query results
for (var i = 0; i < threads.length; i++)
{
// Get messages in thread, add to array
var messages = threads[i].getMessages();
// Used to find max index in array
var max = messages[0];
var maxIndex = 0;
// Loop through array to find maxIndexD = most recent mail
for (var j = 0; j < messages.length; j++) {
if (messages[j] > max) {
maxIndex = j;
max = messages[j];
}
}
// Find data
var mId = messages[maxIndex].getId() // ID used to create mail link
var from = messages[maxIndex].getFrom();
var cc = messages[maxIndex].getCc();
var time = threads[i].getLastMessageDate()
var sub = messages[maxIndex].getSubject();
// Write data to sheet
ss.appendRow([from, cc, time, sub, 'https://mail.google.com/mail/u/0/#inbox/'+mId])
}
}
A: What do you mean by recent?
How about adding newer_than:3d to the search?
You can test the search in your own Gmail account and when it's doing what you want then just paste it into the query. | unknown | |
d1409 | train | If you are not sure about URL encoding, use encodeURIComponent:
var date = encodeURIComponent(date.format());
var id = encodeURIComponent(resId);
To prevent from caching, add to the end some random value. For example:
'&v=' + Math.random() | unknown | |
d1410 | train | Well, a case can be made that the class does something. It changes a status, it starts a timer. You can inject mocks of these objects into the class via Mockito and then make sure, that initialized() and destroy() both do what you expect them to do to these mocks.
@RunWith(MockitoJUnitRunner.class)
public class PipsAlprConnectionRunner {
@Mock
private PipsAlprConfiguration config;
@Mock
private PipsAlprConnector connector;
@Mock
private Scheduler scheduler;
@Mock
private ServiceStatus status;
@InjectMocks
private PipsAlprConnectionRunner pipsAlprConnectionRunner ;
@Test
public void initialized_should_set_status_started() {
pipsAlprConnectionRunner.initialized();
Mockito.verify(status).started();
}
// etc.
}
It's pretty much a question of personal taste if you want to create one method per "point of failure" or one method per method/test.
Personally, I would say that the goal is 100% coverage, so even pretty simple classes that mainly delegate should be covered. What happens if someone changes anything? The test ensures that such changes will not break existing functionality. | unknown | |

A: Try this one
var regexp = /(?:\n| )*view[\s\S\n\r ]+?(?=\n+ *view|$)/g | unknown | |
d1413 | train | If you have dependencies that can be replaced with Google compatible equivalent dependencies then this could be a possible solution to manage both in one code base.
Using app flavours I was able to separate my GMS and HMS dependencies. In your app level build.gradle file you can create product flavour like so
android {
flavorDimensions "platforms"
...
productFlavors {
gms {
dimension "platforms"
}
hms {
dimension "platforms"
}
}
...
}
More on product flavors here.
And then you can specify if a dependency should be part of the flavour by prefixing it to the keyword implementation under dependencies.
dependencies {
...
gmsImplementation 'com.google.android.gms:play-services-maps:18.0.2'
hmsImplementation 'com.huawei.hms:maps:5.0.0.300'
...
}
I then went a bit further by wrapping the usage of each dependency in a class that is available in both flavours but the implementation differs based on the dependency's requirements.
com.example.maps.MapImpl under src>hms>java
and
com.example.maps.MapImpl under src>gms>java
So I am free to use the wrapper class anywhere without worrying about the dependency mismatch.
The HMS dependency is no longer part of the GMS build variant so I would be able to upload that to the Google playstore.
A: I solved it by doing similar to what @Daniel has suggested to avoid such worries in the future:
*
*Create different product flavors in your app level Gradle file:
android {
...
flavorDimensions 'buildFlavor'
productFlavors {
dev {
dimension 'buildFlavor'
}
production {
dimension 'buildFlavor'
}
huawei {
dimension 'buildFlavor'
}
}
}
*Restrict the Huawei related dependencies so they're only available for Huawei product flavor:
huaweiImplementation "com.huawei.hms:iap:3.0.3.300"
huaweiImplementation "com.huawei.hms:game:3.0.3.300"
huaweiImplementation "com.huawei.hms:hwid:5.0.1.301"
huaweiImplementation "com.huawei.hms:push:5.0.0.300"
huaweiImplementation "com.huawei.hms:hianalytics:5.0.3.300"
huaweiImplementation "com.huawei.hms:location:5.0.0.301"
*Since dev and production flavors are not going to have Huawei dependencies now, you may get build errors for the Huawei related classes that you use in your app.
For that I create dummy classes with the same packages tree as Huawei, for instance:
app > src > dev > java > com > huawei > hms > analytics > HiAnalytics.kt
class HiAnalytics {
companion object {
@JvmStatic
fun getInstance(context: Context): HiAnalyticsInstance {
return HiAnalyticsInstance()
}
}
}
*This solves the Cannot resolve symbol error when trying to import Huawei classes in your main, dev, or production flavors and you can import those classes anywhere:
import com.huawei.hms.analytics.HiAnalytics
Now if you change the build variant to dev, you should have access to the dummy classes in your app. If you change it to huawei, you should be able to access the classes from Huawei dependencies.
A: Update:
Note:
If you have confirmed that the latest SDK version is used, before submitting a release to Google, please check the apks in all Testing track on Google Play Console(including Open testing, Closed testing, Internal testing). Ensure that the APKs on all tracks(including paused track) have updated to the latest HMS Core SDK.
HMS Core SDKs have undergone some version updates recently. To further improve user experience, update the HMS Core SDK integrated into your app to the latest version.

A: UPDATE 06/04/2022
Huawei released a new version of their SDK : 3.4.0.300
3.4.0.300 (2022-03-04)
New Features
*
*Real-time translation: Added Afrikaans to the list of languages
supported. (Note that this language is available only in Asia,
Africa, and Latin America.)
Modified Features
*
*Deleted the capability of prompting users to install HMS Core (APK).
*Modified the SDK privacy and security statement. Updated the SDK
*versions of all subservices.
For me, since I've migrated to Google ML Kit, I will wait till August, then I will switch back to Huawei ML Kit to make sure Google will not remove or suspend my apps.
Old answer :
I used to love the HMS ML kit, but because of this issue, I'm aware that Google will one day completely suspend my apps because I'm using HMS services, and even if Huawei fixes the issue, we'll have to wait 120 days to find out if we're safe.
In my case, I'm using the HMS Segmentation ML Kit. I've just switched to Google Selfie Segmentation ML. I will wait till 120 days have passed and see if the issue is still persisting for other developers. If not, I will switch back to the HMS Kit.
A: The solution to the problem is to update the dependencies like in this link.
With this update, the ability to prompt users to install HMS Core (APK) has been removed.
https://developer.huawei.com/consumer/en/doc/development/hmscore-common-Guides/hmssdk-kit-0000001050042513#section20948233203517
A: I just use hms push when upload to huawei.
i fixed by commenting hms services in build.gradle and app/build.gradle when to upload to playstore.
Then, I uncomment if upload to huawei.
//apply plugin: "com.huawei.agconnect"
apply plugin: 'com.google.gms.google-services'
//implementation 'com.huawei.hms:push:5.3.0.304'. | unknown | |
d1414 | train | According to documentation (https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/Acrobat_SDK_developer_faq.pdf) you could send a command to print a file, but there is no parameter for the number of copies.
You can display and print a PDF file with Acrobat and Adobe Reader
from the command line. These commands are unsupported, but have worked
for some developers. There is no documentation for these commands
other than what is listed below.
Note: All examples below use Adobe
Reader, but apply to Acrobat as well. If you are using Acrobat,
substitute Acrobat.exe in place of AcroRd32.exe on the command line.
AcroRd32.exe pathname — Start Adobe Reader and display the file. The
full path must be provided. This command can accept the following
options.
/n Start a separate instance of Acrobat or Adobe Reader, even if one is currently open.
/s Suppress the splash screen.
/o Suppress the open file dialog box.
/h Start Acrobat or Adobe Reader in a minimized window.
AcroRd32.exe /p pathname — Start Adobe Reader and display the Print dialog box.
AcroRd32.exe /t path "printername" "drivername" "portname" — Start Adobe Reader
and print a file while suppressing the Print dialog box. The path must be fully specified.
The four parameters of the /t option evaluate to path, printername, drivername, and portname (all
strings).
printername — The name of your printer.
drivername — Your printer driver’s name, as it appears in your printer’s properties.
portname — The printer’s port. portname cannot contain any "/" characters; if it does, output is
routed to the default port for that printer
For multiple copies of each pdf, you could use a loop.
Something like this:
set shApp = CreateObject("shell.application")
currentPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")
set shFolder = shApp.NameSpace( currentPath )
set files = shFolder.Items()
set oWsh = CreateObject ("Wscript.Shell")
dn = 1
inv = 6
po = 2
for each files in files
msgbox(files)
if inStr(files, "DN") then
for x = 1 to dn
oWsh.run """AcroRd32.exe"" /t /n /h /o /s" &files,,true
next
end if
if inStr(files, "INV") then
for x = 1 to inv
oWsh.run """AcroRd32.exe"" /t /n /h /o /s" &files,,true
next
end if
if inStr(files, "PO") then
for x = 1 to po
oWsh.run """AcroRd32.exe"" /t /n /h /o /s" &files,,true
next
end if
next
MsgBox("completed")

d1415 | train | I just stumbled upon the same issue. To reproduce the problem in the debugger, I had to go to:
Tools\Options
Debugging\General
and disable: Suppress JIT optimization on module load (managed only).
Of course the problem would only appear for a optimized code. | unknown | |
d1416 | train | By default, JList shows the toString value of the object. So there is no need to convert your objects to strings.
You can override that behavior of JList if needed by creating custom cell renderers. See How to Use Lists for more details.
A: You can convert the list to an array and then put it in the list.
ArrayList<OrderItem> myArrayList = new ArrayList<OrderItem>();
OrderItem[] items = new OrderItem[myArrayList.size()];
myArrayList.toArray(items);
myJList = new JList(items);
A: Actually, the toArray() method displays each item in the arrayList. JList doesn't show anything by default. You have to set the visibility according to your needs.
It sounds like you are trying to simply display the object's toString method in the list instead of the full object; in other words, you simply want to display the string representation. instead of the array representation.
You can rewrite the array to represent the data you want to show (provide the "toString construct as the array is built):
ArrayList<> myNewArrayList = new ArrayList<OrderItem>();
for (int i=0; i< oldArray.size(); i++)
{
newArray.add(oldArray.get)i).toString();
}
... rest of code ...
Then use the new array in the panel and use the index as reference to the object array for object processing.

d1417 | train | This is my answer to another post with the same problem solved:
Since MVC4 Razor verifies that what you are trying to write is valid HTML. If you fail to do so, Razor fails.
Your code tried to write incorrect HTML:
If you look at the documentation of link tag in w3schools you can read the same thing expressed in different ways:
*
*"The element is an empty element, it contains attributes only."
*"In HTML the tag has no end tag."
What this mean is that link is a singleton tag, so you must write this tag as a self-closing tag, like this:
<link atrib1='value1' attrib2='value2' />
So you can't do what you was trying to do: use an opening and a closing tag with contents inside.
That's why Razor fails to generate this your <xml> doc.
But there is one way you can deceive Razor: don't let it know that you're writing a tag, like so:
@Html.Raw("<link>")--your link's [email protected]("</link>")
Remember that Razor is for writing HTML so writing XML with it can become somewhat tricky. | unknown | |

label.Top = (this.ClientSize.Height / 2) - (label.Height / 2);

label.Height = this.ClientSize.Height;
}
}
Result:
A: I will suggest you to create a UserControl with TextBox and a Label docked right. That should be pain less and bug free.
As you said you already use TextBox to avoid much refactoring you can add all the properties you used in TextBox as "Proxy properties". Something like this:
class MyTextBox : UserControl
{
public int TextLength { get { return textbox.TextLength; } }
...
}
This can help you to avoid much refactoring.
A: I would actually create a composit control, or simply a UserControl, and put a label and textbox next to each other. Then you can remove the borders around the textbox and surround them with a borderbox to mimic the normal textbox design.
Finally I would make sure that the user controls properties, like Text is mapped to the Textbox, so it is easy to use the control as a drop-replacement. | unknown | |
d1419 | train | This is happening due to a series of unfortunate events.
*
*The problem begins with the fact that HSQLDB does not support the
float data type.
(Duh? Yes, I know, but Documentation
here.)
*The problem starts becoming ugly due to the fact that HSQLDB does
not simply fail when you specify a float column, but it
silently re-interprets it as double. If you later query the type
of that column, you will find that it is not float, it is
double.
A typical example of programmers applying their misguided
notions of "defensive programming", creating far more trouble than
they are saving. HSQLDB is essentially pretending to the
unsuspecting programmer that everything went fine, but it is only
trolling them: nothing went fine, and there will be trouble.
*Then, later, hibernate finds this column to be double, while it
expects it to be float, and it is not smart enough to know that
float is assignable from double, so it fails.
Everyone knows that a double is better than a float, so
hibernate should actually be happy that it found a double while
all it needed was a float, right? --but no, hibernate will not
have any of that: when it expects a float, nothing but a float
will do.
*Then, there is this funny thing about hibernate supposedly having
built-in support for HSQLDB, as evidenced by the fact that it
includes a class org.hibernate.dialect.HSQLDialect, but the
dialect does not take care of floats.
So, they don't believe that a data type incompatibility is a
dialect issue? they never tested it with floats? I don't know what
to suppose, but the truth of the matter is that the hibernate
dialect for HSQLDB does not provide any correction for this
problem.
So, what can we do?
One possible solution to the problem is to create our own hibernate dialect for HSQLDB, in which we correct this discrepancy.
In the past I came across a similar problem with MySQL and boolean vs. bit, (see this question: "Found: bit, expected: boolean" after Hibernate 4 upgrade) so for HSQLDB I solved the problem with float vs. double by declaring my own HSQLDB dialect for hibernate:
/**
* 'Fixed' HSQL Dialect.
*
* PEARL: HSQL seems to have a problem with floats. We remedy this here.
* See https://stackoverflow.com/q/28480714/773113
*
* PEARL: this class must be public, not package-private, and it must have a
* public constructor, otherwise hibernate won't be able to instantiate it.
*/
public class FixedHsqlDialect extends HSQLDialect
{
public FixedHsqlDialect()
{
registerColumnType( java.sql.Types.FLOAT, "double" );
}
}
And using it as follows:
ejb3cfg.setProperty( "hibernate.dialect", FixedHsqlDialect.class.getName() );
//Instead of: org.hibernate.dialect.HSQLDialect.class.getName(); | unknown | |
d1420 | train | Inside of your flawTemplate the scope is caseStudy.selectedCase.Flaws, so when you put caseStudy.showFlawDetails, it is not found as a property of Flaws or globally.
So, you can either reference it with app.viewModel.caseStudy.showFlawDetails, if app has global scope (which it seems to since it works for you).
Otherwise, a good option is to pass the function in via templateOptions. So, you would do:
data-bind='template: { name: "flawTemplate", data: caseStudy.selectedCase.Flaws, templateOptions: showFlawDetails: caseStudy.showFlawDetails } }'>
Then, you would access it using $item.showFlawDetails

d1434 | train | If I'm not mistaken, Company -> Company_GoodsPackagings is a one to many relationship?
Therefore the property Copmany_GoodsPackagings will be a collection and so you will need to use the Any() function as follows:
var theSource = (from g in Data.GoodsTypes
select new
{
gvGoodsType = g.Description,
gvParcels = true,
gvContainers = curCompany.Company_GoodsPackagings.Any(gp => qp.GoodsType == g.Goods_Type && gp.PackagingType1.Description == "Container")
}
EDIT: It seems that my suggestion to use Any() is not supported by Linq to SQL. Therefore I would suggest that you bring back the whole goods packaging object and then check to see if it has a value or not in order to determine boolean gvContainers:
You can then convert your anonymous type into a concrete class and add the property at the end of the example:
var theSource = (from g in Data.GoodsTypes
select new GoodsResult
{
gvGoodsType = g.Description,
gvParcels = true,
gvGoodsPackaging_Container = curCompany.Company_GoodsPackagings.FirstOrDefault(gp => qp.GoodsType == g.Goods_Type && gp.PackagingType1.Description == "Container")
}
public bool gvContainers {
get { return this.gvGoodsPackaging != null }
}
A: The problem is that curCompany.Company_GoodsPackagings is a collection of GoodsPackagings (hence the plural and the mention of System.Data.Linq.EntitySet). You can't therefore refer directly to a single GoodsType for the Company in this way.
I think you're looking for a way to test each one of the Company's GoodsPackagings against your conditions. To do this you can use the Any() Linq extension method:
using System.Linq;

d1440 | train | I believe your problems are traceable to the fact that your mapping table BusUnitDimension has its own primary key, Id, as opposed to the more typical approach in which the BusUnitId and DimensionId FK properties together comprise the compound primary key of BusUnitDimension.
Observe that OrderDetails in Northwind and the HeroPoweMap in the Breeze many-to-many example have compound keys.
Your choice creates complications.
First, it becomes possible to create multiple BusUnitDimension entities representing the same association between BusUnit and Dimension (i.e., they all have the same pair of FKs). The database may be able to prevent this (it's been a long time since I looked) but whether it does or doesn't, it won't prevent you from creating those duplicates in Breeze ... and maybe not in EF either.
Secondly, it opens you up to the problem you're currently facing. If those mapping entities are in the DbContext when you perform the delete, EF may (apparently does) try to null their FK properties as it sets either BusUnit or Dimension to the deleted state.
You can get around this, as has been suggested, by making both the BusUnitId and DimensionId FK properties nullable. But that is contrary to the semantics as a BusUnitDimension must link a real BusUnit to a real Dimension; they aren't optional. The practical consequence may be that you don't get cascade delete from the EF perspective if you do this (not sure if the DB will enforce that either). That means you'd have orphaned BusUnitDimension rows in your database with one or both FKs being null. I speculate because I'm not used to getting into this kind of trouble.
Another approach would be to set their FK values to zero (I think Breeze does this for you). Of course this implies the existence of BusUnit and Dimension table rows with Id == 0, if only during the delete operation.
Btw, you could actually have such "sentinel entities" in your DB.
You must make sure that these BusUnitDimension are in the deleted state or EF (and the DB) will either reject them (referential integrity constraint) or orphan them (you'll have BusUnitDimension rows in your database with one or both FKs being zero).
Alternatively, if you know that the DB will cascade delete them, you can simply remove them from the DbContext (remove from the EntityInfoMap in the EFContextProvider). But now you have to tell the Breeze client to get rid of them too if it happens to have them hanging around.
Enough Already!
These wandering thoughts should tell you that you've got yourself in a jam here with way too much bookkeeping ... and all because you gave BusUnitDimension its own Id primary key.
It gets a lot easier if you give BusUnitDimension the compound key, {BusUnitId, DimensionId}. You must also give it a payload property (anything will do) to prevent EF from hiding it in its "many-to-many" implementation because Breeze doesn't handle that. Adding any nonsense property will do the trick.

A: That has nothing to do with Breeze.. The originating message is from Entity Framework..

d1443 | train | The Standard (RFC 3986 aka STD 66) lays it out for you. In particular, §2 and 2.1:
2. Characters
The URI syntax provides a method of encoding data, presumably for the
sake of identifying a resource, as a sequence of characters. The URI
characters are, in turn, frequently encoded as octets for transport
or presentation. This specification does not mandate any particular
character encoding for mapping between URI characters and the octets
used to store or transmit those characters. When a URI appears in a
protocol element, the character encoding is defined by that protocol;
without such a definition, a URI is assumed to be in the same
character encoding as the surrounding text.
The ABNF notation defines its terminal values to be non-negative
integers (codepoints) based on the US-ASCII coded character set
[ASCII]. Because a URI is a sequence of characters, we must invert
that relation in order to understand the URI syntax. Therefore, the
integer values used by the ABNF must be mapped back to their
corresponding characters via US-ASCII in order to complete the syntax
rules.
A URI is composed from a limited set of characters consisting of
digits, letters, and a few graphic symbols. A reserved subset of
those characters may be used to delimit syntax components within a
URI while the remaining characters, including both the unreserved set
and those reserved characters not acting as delimiters, define each
component's identifying data.
2.1. Percent-Encoding
A percent-encoding mechanism is used to represent a data octet in a
component when that octet's corresponding character is outside the
allowed set or is being used as a delimiter of, or within, the
component. A percent-encoded octet is encoded as a character
triplet, consisting of the percent character "%" followed by the two
hexadecimal digits representing that octet's numeric value. For
example, "%20" is the percent-encoding for the binary octet
"00100000" (ABNF: %x20), which in US-ASCII corresponds to the space
character (SP). Section 2.4 describes when percent-encoding and
decoding is applied.
pct-encoded = "%" HEXDIG HEXDIG
The uppercase hexadecimal digits 'A' through 'F' are equivalent to
the lowercase digits 'a' through 'f', respectively. If two URIs
differ only in the case of hexadecimal digits used in percent-encoded
octets, they are equivalent. For consistency, URI producers and
normalizers should use uppercase hexadecimal digits for all percent-
encodings.
In general, the only characters that may freely be represented in a URL without being percent-encoded are
*
*The unreserved characters. These are the US-ASCII (7-bit) characters
*
*A-Z
*a-z
*0-9
*-._~
*The reserved characters ... when in use as within their role in the grammar of a URL and its scheme. These reserved characters are:
*
*:/?#[]@!$&'()*+,;=
Any other characters, per the standard must be properly percent-encoded.
Further note that a URL may only contains characters drawn from the US-ASCII character set (0x00-0x7F): If your URL contains characters outside that range of codepoints, those characters will need to be suitably encoded for representation in US-ASCII (e.g., via HTML/XML entity references). Further, you application is responsible for interpreting such. | unknown | |

document.getElementById("mySidenav").style.width = "375px";
document.getElementById("root").style.overflow = "hidden";
body.addEventListener('click', closeNavBody)
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("root").style.overflow = "auto";
}
A: You can add an eventListener on the area that is not that element with event.target.
But only do that when nav is open and remove the listener when is closed by removeEventListener() or it would be a load.
A: Get references to the elements we're working with
const mySideNav = document.getElementById("mySidenav");
const root = document.getElementById("root");
const body = document.getelementByTagName("body");
Define our functions
function closeNav() {
mySidenav.style.width = "0";
root.style.overflow = "auto";
body.onclick = undefined;
}
function openNav() {
mySideNav.style.width = "375px";
root.style.overflow = "hidden";
body.onclick = closeNav;
}
A: You can attach a listener to body and call closeNav if sideBar nav is open Also attach click listener to stop propagation when clicked inside nav bar.
<script>
// variable of references to the dom node to avoid querying DOM again and again
const sideNavBarElem = document.getElementById("mySidenav");
const rootElem = document.getElementById("root");
const bodyElem = document.querySelector('body');
function openNav() {
sideNavBarElem.style.width = "375px";
rootElem.style.overflow = "hidden";
// delay attaching body listener to avoid calling body listener when nav has just opened
setTimeout(function() {
bodyElem.addEventListener('click', bodyNavListener);
}, 0);
}
function closeNav() {
sideNavBarElem.style.width = "0";
rootElem.style.overflow = "auto";
bodyElem.removeEventListener('click', bodyNavListener);
}
function bodyNavListener(){
// call closeNav fn if navbar is open
if(sideNavBarElem.style.width !== "0"){
closeNav();
}
}
sideNavBarElem.addEventListener('click', function(event){
// stop event propagation to avoid closing nav bar due to body click listener
event.stopPropagation();
})
</script>

d1446 | train | If you want to keep the results of the operations, which it seems you do as you purposely carry on, then throwing an exception is the wrong thing to do. Generally you should aim not to disturb anything if you throw an exception.
What I suggest is passing the exceptions, or data derived from them, to an error handling callback as you go along.
public interface StoreExceptionHandler {
void handle(StoreException exc);
}
public synchronized void store(StoreExceptionHandler excHandler) {
for (Resource resource : this.resources.values()) {
try {
resource.store();
} catch (StoreException exc) {
excHandler.handle(exc);
}
}
/* ... return normally ... */
]
A: There are guiding principles in designing what and when exceptions should be thrown, and the two relevant ones for this scenario are:
*
*Throw exceptions appropriate to the abstraction (i.e. the exception translation paradigm)
*Throw exceptions early if possible
The way you translate StoreException to MultipleCauseException seems reasonable to me, although lumping different types of exception into one may not be the best idea. Unfortunately Java doesn't support generic Throwables, so perhaps the only alternative is to create a separate MultipleStoreException subclass instead.
With regards to throwing exceptions as early as possible (which you're NOT doing), I will say that it's okay to bend the rule in certain cases. I feel like the danger of delaying a throw is when exceptional situations nest into a chain reaction unnecessarily. Whenever possible, you want to avoid this and localize the exception to the smallest scope possible.
In your case, if it makes sense to conceptually think of storing of resources as multiple independent tasks, then it may be okay to "batch process" the exception the way you did. In other situations where the tasks has more complicated interdependency relationship, however, lumping it all together will make the task of analyzing the exceptions harder.
In a more abstract sense, in graph theory terms, I think it's okay to merge a node with multiple childless children into one. It's probably not okay to merge a whole big subtree, or even worse, a cyclic graph, into one node. | unknown | |

This is a batch/vbscript hybrid (you need to save it as a batch) .I don't think is possible to do this with simple batch.On windows 8/8.1 might require download of windows media player (the most right column).Some anti-virus programs could warn you about this script.
A: I know this question is old, but I wanted to share this:
@echo off
echo Set oWMP = CreateObject("WMPlayer.OCX.7") >> %temp%\temp.vbs
echo Set colCDROMs = oWMP.cdromCollection >> %temp%\temp.vbs
echo For i = 0 to colCDROMs.Count-1 >> %temp%\temp.vbs
echo colCDROMs.Item(i).Eject >> %temp%\temp.vbs
echo next >> %temp%\temp.vbs
echo oWMP.close >> %temp%\temp.vbs
%temp%\temp.vbs
timeout /t 1
del %temp%\temp.vbs
just make sure you don't have a file called "temp.vbs" in your Temp folder. This can be executed directly through a cmd, you don't need a batch, but I don't know any command like "eject E:\". Remember that this will eject all CD trays in your system.
A: UPDATE:
A script that supports also ejection of a usb sticks - ejectjs.bat:
::to eject specific dive by letter
call ejectjs.bat G
::to eject all drives that can be ejected

d1450 | train | One example that comes to mind is in a cross-site ajax request, it is easy to send a text/html request which will not generate a pre-flight request, but it is not possible with applictaion/json. So if you have a service with a POST action that expects json and changes server state, it may be possible to exploit CSRF if text/html is accepted for the content type, but there is some basic protection if application/json is verified, because the browser will not send the request from a different domain if the response to the pre-flight does not explicitly allow a CORS post.
So some properties of cross-domain ajax requests depend on the content type. I think this may be the main reason.
Also from a more theoretical standpoint, the format of the data is needed to parse it. I cannot think of an actual exploit, but at least in theory, trying to parse data in a wrong format may lead to the wrong results, things parsed different from what they were supposed to be. It's best to just validate that the client is actually sending what it claims, and what it should be. | unknown | |

d1452 | train | You appear to have an issue with the underlying generated Thrift code. Unless you have a specific reason to do so, using Thrift directly to access Cassandra is not recommended. There are many client libraries available that will abstract this for you.
Having said that, I have used the Thrift-generated C# code to write my own library in the past, and have not run into this issue. Perhaps your problem has something to do with your use of VB? If you have some reason to use Thrift directly, you might try the same code in C# to see if that resolves the issue. If not, make sure you have the right versions of Cassandra and Thrift, as incompatibilities there can cause issues such as this. | unknown | |

d1454 | train | I have checked your class name coreSpriteRightPaginationArrow and i couldn't find any element with that exact class name. But I saw the class name partially. So it might help if you try with XPath contains as shown below.
//div[contains(@class,'coreSpriteRight')]
another xpath using class wpO6b. there are 10 elements with same class name so filtered using @aria-label='Next'
//button[@class='wpO6b ']//*[@aria-label='Next']
Try these and let me know if it works.
I have tried below code and it's clicking next button for 10 times
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
if __name__ == '__main__':
driver = webdriver.Chrome('/Users/yosuvaarulanthu/node_modules/chromedriver/lib/chromedriver/chromedriver') # Optional argument, if not specified will search path.
driver.maximize_window()
driver.implicitly_wait(15)
driver.get("https://www.instagram.com/instagram/");
time.sleep(2)
driver.find_element(By.XPATH,"//button[text()='Accept All']").click();
time.sleep(2)
#driver.find_element(By.XPATH,"//button[text()='Log in']").click();
driver.find_element(By.NAME,"username").send_keys('username')
driver.find_element(By.NAME,"password").send_keys('password')
driver.find_element(By.XPATH,"//div[text()='Log In']").click();
driver.find_element(By.XPATH,"//button[text()='Not now']").click();
driver.find_element(By.XPATH,"//button[text()='Not Now']").click();
#it open Instagram page and clicks 1st post and then it will click next post button for the specified range
driver.get("https://www.instagram.com/instagram/");
driver.find_element(By.XPATH,"//div[@class='v1Nh3 kIKUG _bz0w']").click();
for page in range(1,10):
driver.find_element(By.XPATH,"//button[@class='wpO6b ']//*[@aria-label='Next']" ).click();
time.sleep(2)
driver.quit()
A: As you can see on the picture below, the wp06b button is inside a lot of divs, in that case you might need to give Selenium that same path of divs to be able to access the button or give it a XPath.
It's not the most optimized but should work fine.
driver.find_element(By.XPATH("(.//*[normalize-space(text()) and normalize-space(.)='© 2022 Instagram from Meta'])[1]/following::*[name()='svg'][2]")).click()
Note that the XPath leads to a svg, so basically we are clicking on the svg element itself, not in the button.
A: As you can see, the next post right arrow button element locator is changing between the first post to other posts next page button.
In case of the first post you should use this locator:
//div[contains(@class,'coreSpriteRight')]
While for all the other posts you should use this locator
//a[contains(@class,'coreSpriteRight')]
The second element //a[contains(@class,'coreSpriteRight')] will also present on the first post page as well, however this element is not clickable there, it is enabled and can be clicked on non-first pages only. | unknown | |

d1456 | train | A handle of my Activity in the Adapter and the runQuery call in the filter makes a call to startManagingCursor on the Activity whenever the runQuery is called. This is not ideal because a background thread is calling startManagingCursor and also there could be a lot of cursors remaining open until the Activity is destroyed.
I added the following to my Adapter which has a handle on the Activity it is used within
@Override
public void changeCursor(Cursor newCursor) {
Cursor oldCursor = getCursor();
super.changeCursor(newCursor);
if(oldCursor != null && oldCursor != newCursor) {
// adapter has already dealt with closing the cursor
activity.stopManagingCursor(oldCursor);
}
activity.startManagingCursor(newCursor);
}
This makes sure that the current cursor used by the adapter is also managed by the activity. When the cursor is closed by the adapter management by the activity is removed. The last cursor held by the adapter will be closed by the activity by way of it still be managed by the activity. | unknown | |

for (int i = 0; i < numOfAgents; i++)
encryptArr[i] = agentArr[i];
Each value in the array is something that meets all requirements of an "object", and can be copied/moved as a whole. No need to bother copying each member of the struct.
A: You should use std::string instead of char arrays. It is assignable and there are more merits including almost unlimited length of string.
struct Agent
{
std::string name;
int idNum;
double years;
std::string location;
};
If you are unfortunately forced to use arrays for some reason, you will have to assign each elements.
If it is guaranteed that the contents of the arrays will always be strings (sequences of characters terminated by null-character), you can use strcpy() to copy them.
(I will show only code for name, but location should also be treated like this)
strcpy(encryptArr[i].name, agentArr[i].name);
If you cannot guarantee this, you should use memmove() (because memcpy() is banned here).
memmove(encryptArr[i].name, agentArr[i].name, sizeof(encryptArr[i].name));
If memmove() is also unfortunately banned, the last option will be assigning the elements one-by-one.
for (int j = 0; j < C_STRING_SIZE; j++)

encrypyArr[i].name[j] = agentArr[i].name[j];

d1465 | train | I fixed the scroll up issue using the following code :
private RecyclerView.OnScrollListener scrollListener = new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
LinearLayoutManager manager = ((LinearLayoutManager)recyclerView.getLayoutManager());
boolean enabled =manager.findFirstCompletelyVisibleItemPosition() == 0;
pullToRefreshLayout.setEnabled(enabled);
}
};
Then you need to use setOnScrollListener or addOnScrollListener depending if you have one or more listeners.
A: Unfortunately, this is a known issue and will be fixed in a future release.
https://code.google.com/p/android/issues/detail?id=78191
Meanwhile, if you need urgent fix, override canChildScrollUp in SwipeRefreshLayout.java and call recyclerView.canScrollVertically(mTarget, -1). Because canScrollVertically was added after gingerbread, you'll also need to copy that method and implement in recyclerview.
Alternatively, if you are using LinearLayoutManager, you can call findFirstCompletelyVisibleItemPosition.
Sorry for the inconvenience.
A: You can disable/enable the refresh layout based on recyclerview's scroll ability
public class RecyclerSwipeRefreshHelper extends RecyclerView.OnScrollListener{
private static final int DIRECTION_UP = -1;
private final SwipeRefreshLayout refreshLayout;
public RecyclerSwipeRefreshHelper(
SwipeRefreshLayout refreshLayout) {
this.refreshLayout = refreshLayout;
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
refreshLayout.setEnabled((recyclerView.canScrollVertically(DIRECTION_UP)));
}
}
A: override RecyclerView's method OnScrollStateChanged
mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
// TODO Auto-generated method stub
//super.onScrollStateChanged(recyclerView, newState);
try {
int firstPos = mLayoutManager.findFirstCompletelyVisibleItemPosition();
if (firstPos > 0) {
mSwipeRefreshLayout.setEnabled(false);
} else {
mSwipeRefreshLayout.setEnabled(true);
if(mRecyclerView.getScrollState() == 1)
if(mSwipeRefreshLayout.isRefreshing())
mRecyclerView.stopScroll();
}
}catch(Exception e) {
Log.e(TAG, "Scroll Error : "+e.getLocalizedMessage());
}
}
Check if Swipe Refresh is Refreshing and try to Scroll up then you got error, so when swipe refresh is going on and i try do this mRecyclerView.stopScroll();
A: You can override the method canChildScrollUp() in SwipeRefreshLayout like this:
public boolean canChildScrollUp() {
if (mTarget instanceof RecyclerView) {
final RecyclerView recyclerView = (RecyclerView) mTarget;
RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
if (layoutManager instanceof LinearLayoutManager) {
int position = ((LinearLayoutManager) layoutManager).findFirstCompletelyVisibleItemPosition();
return position != 0;
} else if (layoutManager instanceof StaggeredGridLayoutManager) {
int[] positions = ((StaggeredGridLayoutManager) layoutManager).findFirstCompletelyVisibleItemPositions(null);
for (int i = 0; i < positions.length; i++) {
if (positions[i] == 0) {
return false;
}
}
}
return true;
} else if (android.os.Build.VERSION.SDK_INT < 14) {
if (mTarget instanceof AbsListView) {
final AbsListView absListView = (AbsListView) mTarget;
return absListView.getChildCount() > 0
&& (absListView.getFirstVisiblePosition() > 0 || absListView.getChildAt(0)
.getTop() < absListView.getPaddingTop());
} else {
return mTarget.getScrollY() > 0;
}
} else {
return ViewCompat.canScrollVertically(mTarget, -1);
}
}
A: Following code is working for me, please ensure that it is placed below the binding.refreshDiscoverList.setOnRefreshListener{} method.
binding.swipeToRefreshLayout.setOnChildScrollUpCallback(object : SwipeRefreshLayout.OnChildScrollUpCallback {
override fun canChildScrollUp(parent: SwipeRefreshLayout, child: View?): Boolean {
if (binding.rvDiscover != null) {
return binding.recyclerView.canScrollVertically(-1)
}
return false
}
})
A: Based on @wrecker answer (https://stackoverflow.com/a/32318447/7508302).
In Kotlin we can use extension method. So:
class RecyclerViewSwipeToRefresh(private val refreshLayout: SwipeToRefreshLayout) : RecyclerView.OnScrollListener() {
companion object {
private const val DIRECTION_UP = -1
}
override fun onScrolled(recyclerView: RecyclerView?, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
refreshLayout.isEnabled = !(recyclerView?.canScrollVertically(DIRECTION_UP) ?: return)
}
}
And let's add extension method to RecyclerView to easly apply this fix to RV.
fun RecyclerView.fixSwipeToRefresh(refreshLayout: SwipeRefreshLayout): RecyclerViewSwipeToRefresh {
return RecyclerViewSwipeToRefresh(refreshLayout).also {
this.addOnScrollListener(it)
}
}
Now, we can fix recyclerView using:
recycler_view.apply {
...
fixSwipeToRefresh(swipe_container)
...

d1466 | train | In order to achieve this, you need to read details from client side using hidden field. This hiddenfield value can be set at server side.
For example:
create hidden field on page
<asp:HiddenField id="hdnDate" runat="server" />
set date string in hiddenField :
protected void button_Clicked (...)
{
DateTime dt = DateTime.Now;
hdnDate.Value = dt.Year.ToString() + "," + (dt.Month - 1 ).ToString() + "," + dt.Day.ToString();
}
now, on document.ready of jquery event, do this
$(document).ready(function() {
$("#dateTextBox").datepicker({
changeMonth: true,
changeYear: true

d1468 | train | You can either populate the documents in the index via code or use an indexer that can create your documents. Here is the Indexer data source drop down showing the different data sources available.
You could put the information about the image and a path to the image in any of these data sources and have an indexer pick it up and create your documents within the index.
If you don't want to use a formal database, you could also upload your images into blob storage and decorate each blob with custom metadata. When creating your index with an indexer, it will find the custom metadata and it can become fields on documents within your index.
There are lots of options, but my advice is to keep your documents within your index as small as possible to control your costs. That's usually done by having as few a fields as possible and have fields that reference where the stuff is located. The documents within an index are for discovering where things are located and NOT for storing the actual data. When you index start occupying lots of space, your cost will go up a LOT. | unknown | |

d1475 | train | If I understand correctly, you're asking where to perform redirection after a user logs in, but not in the technical sense of how to do it but in an architectural sense of where is the right place to do it.
Let's go over the options you have:
*
*Redirect in the effect - This is your first option, redirecting in the effect before or after dispatching a success action to the reducer.
*Redirecting from the service - You can also redirect after the service for example like this:
myService(): void {
return this.http.get(url).pipe(
tap(() => this.router.navigate([navigationURL]))
)
}
*Other options - other options are possible, in your question you asked if there's something that allows to listen to actions, well that's pretty much what effects are for, to listen to actions, but you could also listen to Observable emittions with subscribe, and redirect when that happens, I DO NOT recommend that approach.
I think that adding subscriptions is adding unnecessary complexity to the project, because subscriptions have to be managed.
So what to do?
Honestly, this is up to you, both options seems valid and I wouldn't say either is a bad practice. I personally prefer to keep my effects clean and do it in the service. I feel like the service is better suited to handle side effects, and it makes it a bit cleaner also when testing, but this is my personal opinion.
The important thing to remember is, both options are valid and don't add unnecessary complexity.
There's also one small case which might apply to you, if you need that the user will be in the store before redirecting, it might be better to put this in the effects after dispatching an actions to the reducer. If you're working with Observables it will work either way, but it might be easier to understand if they have tight relationship. | unknown | |

This is because Export-CSV and ConvertTo-CSV run 90% of the same code. They share the same helper-class Microsoft.PowerShell.Commands.ExportCsvHelper to create the header and convert objects to csv. The only difference is that ConvertTo-CSV writes the CSV-object(string) to the pipeline using WriteObject(), while Export-CSV directly writes it to a file using a StreamWriter.
To find this yourself, you could look inside Microsoft.PowerShell.Commands.Utility.dll. I won't be posting the code directly because I'm not sure if it's legal or not. :-)
If you need the CSV-output to be displayed or sent through a third-party API etc., then use ConvertTo-CSV. If you need the data stored in a CSV-file, then you should use Export-CSV. | unknown | |
d1477 | train | You defined the class SynthVoice in the header SynthVoice.H
class SynthVoice : public juce::SynthesiserVoice

and then redefined it in the file SynthVoice.cpp with member function definitions
class SynthVoice : public juce::SynthesiserVoice

If you want to define member functions declared in the class defined in the header then what you need is to write for example
bool SynthVoice::canPlaySound(juce::SynthesiserSound* sound)

d1479 | train | num = [[0,5], [1,5], [3,7]] isn't working?
A: There is a lot of ways to resolve your issue. You're looking for an array of arrays. I think you're confused by how an array can be inside an array. You should keep in mind that an array is just an ordered list of objects. So storing in array in each index is not as foreign as a concept as it may seem.
A = [] #an empty array
A[0] = [1, 2]
A[1] = 1
A # => [[1,2], 1]
If you want to initialize an array with a default value as an array try
A = Array.new(2) {Array.new(2){0}} #This creates an array of size 2 with default values of arrays of size 2 with 0 in each entry.
A[0][1] # returns 0
A[0] # returns [0, 0]

But in your buttonAction it is different. Interchange in viewDidLoad if buttonAction is correct.
A: I suspect Anusha got it. But I also suspect you would easily have found it yourself if you'd chosen a slightly different style. The toggle is either on or off, in other words a perfect match for a boolean. If you had a BOOL named swicthedOn you'd have checks reading if (switchedOn) which would improve readability a lot.
Something like this perhaps:
- (IBAction)theSwitch:(id)sender { // Not using the sender for anything (?)
NSUserDefaults *toggle = [NSUserDefaults standardUserDefaults];
BOOL audioOn = NO;
float toggleX = 924.0f;
if (_switchIsOn) {
toggleX = 985.0f;

*What is the domain? PipelineConfiguration.
*What is the return type? A "function that takes RDDLP and returns RDDLP", that is: (RDDLabeledPoint => RDDLabeledPoint).
All together:
type FTDataReductionProcess =

Since => is right-associative, you can also write:
type FTDataReductionProcess =
PipelineConfiguration => RDDLabeledPoint => RDDLabeledPoint
By the way: the same works for function literals too, which gives a nice concise syntax. Here is a shorter example to demonstrate the point:
scala> type Foo = Int => Int => Double // curried function type

scala> val f: Foo = x => y => x.toDouble / y // function literal
f: Foo = $$Lambda$1065/1442768482@54089484

d1484 | train | Your cart should be clearing after checkout so something else may be wrong.
You could create a function with empty_cart() in it that is triggered when payment is complete "just in case".
See: http://docs.woothemes.com/wc-apidocs/class-WC_Cart.html
add_filter( 'woocommerce_payment_complete_order_status', 'pg_woocommerce_payment_complete_order_status', 10, 2 );
function pg_woocommerce_payment_complete_order_status ( $order_status, $order_id ) {
$global $woocommerce;
$woocommerce->cart->empty_cart();
}
A: You can user this hook :
function custom_empty_cart( $order_id, $data ) {
// delete current cart item here
}
add_action( 'woocommerce_checkout_order_processed', 'custom_empty_cart', 11, 2 );
Or you can check woocommerce hook list from here.
A: The cart should empty as this feature is standard, empty_cart();
Are you using any cache-plugins? In that case you need to exclude the cart page
http://docs.woothemes.com/document/configuring-caching-plugins/
It could also be a problem with the payment-gateway, make sure you have updated to the latest version.
A: i found a similar question but it clears the cart on the click of a button..
http://wordpress.org/support/topic/add-an-empty-cart-button-to-cart-page seems to have worked for some user..
here is the code , it should go in to the function.php file
add_action('init', 'woocommerce_clear_cart_url');
function woocommerce_clear_cart_url() {
global $woocommerce;
if( isset($_REQUEST['clear-cart']) ) {
$woocommerce->cart->empty_cart();
}
}
this is the code for the button
<input type="submit" class="button" name="clear-cart" value="<?php _e('Empty Cart', 'woocommerce'); ?>" />
im guessing u dont need a button, so in the next page when u want the cart to be empty, u can explicitly call this function _e('Empty Cart', 'woocommerce');
for example if it you would like to clear the cart in a post page whose title is Payment Success
if(is_single('Payment Success'))
_e('Empty Cart', 'woocommerce');
or if its slug is payment-success
is_single('payment-success');
_e('Empty Cart', 'woocommerce');
similarly to check if its homepage you can use
is_front_page();
or if its on the wordpress page u can use this
if(is_page( 'Payment Success' ))
_e('Empty Cart', 'woocommerce');
if(is_page( 'payment-success' ))
_e('Empty Cart', 'woocommerce');
you can include the above code in the head section of your wordpress site!!

d1486 | train | Compatibility is an administrative function, not a development or deployment function. It is better to fix the application where possible, especially to remove any requirement for elevation.
There are plenty of tools for investigating the issues so you can correct them. However globally registering "plug ins" at runtime is a nasty one. VB6 component self-registration is always global unless registry virtualization can redirect it. Why not create installers for the plug-ins that can run elevated once during installation?
There are ways to set compatibility less manually, even as part of installation - though Microsoft discourages this. Maybe take a look at:
Compatibility Fix Database Management Strategies and Deployment
However the effort required might be better spent on remediating the problem. Support costs will be less over time.
A: As the other answers have said, you shouldn't need to run all the time elevated.
If you want to register the plugins after its started (as a normal user), you can use ShellExecute() with the "runas" verb to run regsvr32.exe, or use COM elevation which has been discussed many times before.
A: You can indicate that an application must run as admin by specifying it in the Application Manifest, which in an xml file that you can either embed or deploy with your application.
Once your application is running with admin rights it should be able to register and load the plugins. You should not need to run in compatibility mode to access the COM plugins. | unknown | |
d1487 | train | You can use two Grid or GroupBox (or other container type) controls and put appropriate set of controls in each of them. This way you can just visibility of panels to hide the whole set of controls instead of hiding each control directly.
It may sometimes be appropriate to create a user control for each set of controls. However, this can depend on a specific case. | unknown | |
d1488 | train | Your question is a bit unclear, and you might want to provide more detail, but I suspect that you want only one foreign key property on your class two. Depending on how you're creating these objects, this may also be happening because you're trying to reference an id that's 0, because the object has not yet been saved to the database, so it has not been assigned an id.
A: If you are trying to have 1 to 0 or 1 relationship between class one and class two then you need to have primary key and foriegn key same in class 2 and it should be primary key of class one
Class One { ID (PK), Property 2; }
Class Two { One_ID (PK, FK), Nullable_One_ID (FK) } | unknown | |
d1489 | train | The answer is in this snippet:
var aData = request.responseXML...
You're expecting XML. An & by itself is not legal XML. You need to output your result like this:
SUPPORT ASSY-FUEL TANK MOUNTING, R&R (LH) (L-ENG)
A: It's very difficult to tell without seeing your output script, but the first thing to try is to mask the ampersand: &
The neater way, though, would be to add CDATA to your XML output:
<data><![CDATA[SUPPORT ASSY-FUEL TANK MOUNTING, R&R (LH) (L-ENG)]]></data>
your XML parser on client side should understand it no problem.
A: You escape the ampersand by using the HTML eqv. &
A: If you are unable to alter the XML output from the server (it's not your app or some other issue), a "hack" fix would be:
function htmlizeAmps(s){
return s.replace(/\x26/g,"&"); //globalreplace "&" (hex 26) with "&"

d1491 | train | The boolean flag solution is fragile as it is not guaranteed that updates will be visible across different threads. To fix this problem you may declare it as volatile, but if you set the boolean flag you don't interrupt the sleep call like in first version. Thus using interrupts is preferred.
I see no reason to declare Thread tn as static. You may use:
public class GetInfo implements Runnable {
private final Thread tn;
private GetInfo() {
this.tn = new Thread(this);
this.tn.start();
}
public static GetInfo StartPointerInfo() {
GetInfo info = new GetInfo();
System.out.println("After start1");
return info;
}
public void StopPointerInfo() {
tn.interrupt();
}
...
}
And use it like this:
GetInfo infoWorker = GetInfo.StartPointerInfo();
...
infoWorker.StopPointerInfo();
A: You don't need to use a static Thread.
Within the run() method, you need to test whether the current thread has been interrupted. You don't need access to tn for that. You can do this like this:
Thread.currentThread().isInterrupted();
or
Thread.interrupted();
(Note that the behavior of these two are different. One clears the interrupt flag and the other doesn't.)
Alternatively, you could just change the static field to an instance field, and make all of the GetInfo methods instance methods. That means you can instantiate multiple instances of GetInfo which each create their own Thread and hold the reference in the instance field.
Two more points:
*
*The way that you are creating and then disposing of threads is rather inefficient. (Starting a thread is expensive.) A better way is to restructure the code so that it can use a thread pool.
*Calling your methods StartPointerInfo and StopPointerInfo is BAD STYLE. Java method names should always start with a lowercase letter. | unknown | |
d1492 | train | The problem lies in the getGenericTextView() method of the sample code:
// Set the text starting position
textView.setPadding(36, 0, 0, 0);
setPadding(...) sets the padding (intrinsic space) in pixels, meaning the result of this indenting approach will differ per device. You seem to be using an hdpi device with a relatively large horizontal screen resolution, resulting in visually too little space on the lefthand side of the TextView. For some more explanation on this issue, please read the documentation here.
That being said, you can easily overcome the problem by setting a density independent pixel (d(i)p) value, such that the visually indented space will be identical across different resolutions. You can use the TypedValue utility class for this:
int dips = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 36, getResources().getDisplayMetrics());
Alternatively you could inflate a TextView from xml, on which you can set the density independent properties at design time, in stead of doing it on the fly at runtime. | unknown | |
d1493 | train | How about:
<?php
$alphas = range('a', 'z');
$alphacount = count($alphas);
$a = 0;
for ($i=0;$i<$alphacount;$i++) {
$first = $alphas[$a];
$second = $alphas[$i];
if ($i >= $alphacount && $a < $alphaminus ) {
$i = 0;
$a ++;
}
echo "$first$second<br>";
}
So you don't have to to -1 since you don't like it! :)
And how about:
$alphas = range('a', 'z');
for ($i = 0; $i < count($alphas); $i++) {
for ($a = 0; $a < count($alphas); $a++) {
echo "{$alphas[$i]}{$alphas[$a]}\n";
}
}
Or forget about arrays! This is more fun :)
array_walk($alphas, function ($a) use ($alphas) {
array_walk($alphas, function ($b) use ($a) {
print "$a$b\n";
});
});
A: The problem is that you reset $i to 0 in the loop; then on encountering the end of the loop $i is incremented, so the next run in the loop will be with $i = 1 instead of $i = 0.
That is, the next subrange of letters starts with (letter)b instead of (letter)a. (See your output: the next line after az is bb rather than ba.)
Solution: reset $i to -1 in the loop, then at the end it will run with the value 0 again.
A: You have 26 characters, but arrays in PHP are indexed from 0. So, indexes are 0, 1, ... 25.
A: count is 1-based and arrays created by range() are 0-based.
It means that:
$alphas[0] == a
$alphas[25] == z
$count($alphas) = 26; // there are 26 elements. First element is $alphas[0]
A: Why does it have to be so complicated? You could simply do
foreach ($alphas as $alpha)
{
foreach($alphas as $alpha2)
{
echo $alpha.$alpha2."<br>";
}
}
Note: It is mostly not a good idea to manipulate the loop counter variable inside the body of that very loop. You set $i to 0 on a certain condition. That could give you unexpected results, hence the reason why you have to navigate around it. | unknown | |
d1494 | train | First, I'll assume you're using some kind of List - likely an ArrayList.
That said, the main operations for Bubble Sort are described as follows:
*
*Compare for ordering
*Create temporary variable
*Place left value into temporary variable
*Place right value into left value
*Place old left value into right value from temporary value
You're shuffling about the fields, which will lead to confusion and bugs. Use the above approach instead.
Here it is illustrated with generics (so you don't have to cast anymore), and a capital class name, as is the convention. I don't have a temporary variable in this example, as I already have a reference to current.
List<ShowInfo> show = new ArrayList<>(); // assume populated
public static void sortDay(){
for(int i = 0; i < show.size(); i++) {
for(int j = 0; j < show.size() && j != i; j++) {
ShowInfo current = show.get(i);
ShowInfo next = show.get(j);
// If the current day is greater than the next day, we need to swap.
// Adjust to suit your business logic (if current is less than next).
if (current.day.compareTo(next.day) > 0) {
show.set(i, next);
show.set(j, current);
}
}
}
}
A: For a generic way of doing this, perhaps you could try something like:
public static <T extends Comparable> void sort(final List<T> list){
boolean remaining;
do{
remaining = false;
for(int i = 0; i < list.size()-1; i++){
final T current = list.get(i);
final T next = list.get(i+1);
if(current.compareTo(next) < 0){
list.set(i, next);
list.set(i+1, current);
remaining = true;
}
}
}while(remaining);
}
A: How do you fix it?
I'm just answering your question: how to fix the code you posted. For "how to improve it?" all other answers are way better than whatever I can come up with.
There are two points:
*
*swap on the same index, in the inner for (index j)
*correct swapping: where you have j write j+1 and where you have i write j
*the other for is just so it will iterate enough times to get it sorted in the worst case (suggestions in other answers go for a while, much better)
That being said, the swapping pseudocode is:
if (show[j] < show[j+1]) {
temp = j+1
j+1 = j
j = temp
}
And here is the swapping code with the fixes:
if (current.day.compareTo(next.day) < 0) {
showInfo temp = new showInfo();
temp.name = ((showInfo)show.get(j+1)).name;
temp.day = ((showInfo)show.get(j+1)).day;
temp.time = ((showInfo)show.get(j+1)).time;
((showInfo)show.get(j+1)).time = ((showInfo)show.get(j)).time;
((showInfo)show.get(j+1)).day = ((showInfo)show.get(j)).day;
((showInfo)show.get(j+1)).name = ((showInfo)show.get(j)).name;
((showInfo)show.get(j)).time = temp.time;
((showInfo)show.get(j)).day = temp.day;
((showInfo)show.get(j)).name = temp.name;
}
And here is the printed result (assuming day - time - name for each show, so we are sorting on the first int):

610 - -72 - 1402

-478 - 248 - 934
709 - 832 - -590
2007 - 954 - -315

2007 - 954 - -315
838 - -184 - 1096
709 - 832 - -590

d1496 | train | You are over-complicating the solution. All you really need is to determine the size of the label when all the text is added. Once you have determined that, lock the label size to those dimensions, put it inside of a table that expands to fill up the area around it, and then update your label with the action. (You can use a pool and such as needed, but for simplicity I left that out of the code below).
You will have to obviously adapt the code to yours, but this gives you a code reference to what I mean.
Here is a code snippet on one way to do it:
stage = new Stage(Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), false);
Gdx.input.setInputProcessor(stage);
uiSkin = new Skin(Gdx.files.internal("skin/uiskin.json"));
Table fullScreenTable = new Table();
fullScreenTable.setFillParent(true);
final String message = "hello";
final Label progressLabel = new Label(message, this.uiSkin);
final TextBounds bounds = progressLabel.getTextBounds(); // Get libgdx to calc the bounds
final float width = bounds.width;
final float height = bounds.height;
progressLabel.setText(""); // clear the text since we want to fill it later
progressLabel.setAlignment(Align.CENTER | Align.TOP); // Center the text
Table progressTable = new Table();
progressTable.add(progressLabel).expand().size(width, height).pad(10);
final float duration = 3.0f;
final TextButton button = new TextButton("Go!", this.uiSkin);
button.addListener(new ClickListener() {
@Override public void clicked(InputEvent event, float x, float y) {
progressLabel.addAction(new TemporalAction(duration){
LabelFormatter formatter = new LabelFormatter(message);
@Override protected void update(float percent) {
progressLabel.setText(formatter.getText(percent));
}
});
}
});
stage.addActor(button);
fullScreenTable.add(progressTable);
fullScreenTable.row();
fullScreenTable.add(button);
stage.addActor(fullScreenTable);
Edit:
Added code to center and top align text in label. Also added code to fill spaces on the end to allow for proper alignment. Note: Only useful for mono-spaced fonts.
class LabelFormatter {
private final int textLength;
private final String[] data;
private final StringBuilder textBuilder;
LabelFormatter(String text) {
this.textBuilder = new StringBuilder();
this.data = text.split("\n");
int temp = 0;
for (int i = 0 ; i < data.length; i++) {
temp += data[i].length();
}
textLength = temp;
}
String getText(float percent) {
textBuilder.delete(0, textBuilder.length());
int current = Math.round(percent * textLength);
for (final String row : data) {
current -= row.length();
if (current >= 0) {
textBuilder.append(row);
if (current != 0) {
textBuilder.append('\n');
}
} else {
textBuilder.append(row.substring(0, row.length() + current));
// Back fill spaces for partial line
for (int i = 0; i < -current; i++) {
textBuilder.append(' ');
}
}
if (current <= 0) {
break;
}
}
return textBuilder.toString();
}

d1497 | train | Is this meant to get you your UIApplication singleton? (i'm guessing MyAppalloc is a typo and should be MyApp alloc)
MyApp *myApp2 = [[[MyApp alloc] init] autorelease];
if so then you should be doing it like this:
MyApp *myApp2 = (MyApp*)[UIApplication sharedApplication];
If this is not the case you need to make it clearer what MyApp is (your app delegate?)
A: I guess, your application running in singleton instance, if this is something kind of NSView or a particular control you want to refresh, you could call its particular refresh method like,
[NSTableView reload];
[NSTextField setString];
etc... | unknown | |
d1498 | train | If you want the variables to be avaialble in the URL you need to read them with $_GET.
Getting the arguements from a url such as index.php?id=1&job_number_id=3 will look like that:
if (isset($_GET['id']) && isset($_GET['job_number_id'])) {//make sure both arguments are set
$id = $_GET['id'];
$job_number_id = $_GET['job_number_id'];
}
To set it in your foreach statement:
<?php foreach ($allJobs as $site_title) : ?>
<p>
<tr><?php
$url = "http://localhost/estimate_lar/homepage.php?id=" . $site_title['id'] . "&job_number_id=" . $site_title['job_number_id'];
echo '<a href="'.$url.'">'.$site_title['client_job_name'],$site_title['job_number_id']. '<br />'.'</a>';
?>
<td></td>
</tr>
</p>
<?php endforeach; ?>
PLEASE remember to read about SQL injection and making sure you are escaping your inputs. Or even better - use a prepared statement.
Currently your script is volunerable, since everyone could just alter the URL and manipluate your DB.
Hope this helps!
A: Try this.
<?php
session_start();
$id = $_SESSION['id'];
$url = 'http://localhost/estimate_lar/homepage.php';
if($id){
$query = "SELECT id, client_job_name, job_number_id FROM `job_name` WHERE `id`='$id'";
$allJobs = $db->query($query);
}else{
echo "Id not in session";
}
?>
<table>
<?php if ($allJobs) { foreach ($allJobs as $site_title) : ?>
<tr>
<td>
<a href="<?php echo $url; ?>?client_job_name=<?php echo $site_title['client_job_name'];?>&job_number_id=<?php echo $site_title['job_number_id'];?> "> <?php echo $site_title['job_number_id']. " ".$site_title['job_number_id']; ?></a>
</td>
</tr>
<?php endforeach; ?>
</table>
<?php }else{ echo 'No results Found' ;} ?>

d1499 | train | The most likely cause is typos in field names. Each bracketed field name that doesn't correctly match the field name that you are trying to access in the tables is one missing parameter, as far as the parser is concerned. | unknown | |
d1500 | train | You can (as mentioned in the error message) move the 'Access to the private part of the package spec:
private with external;
generic
flag : Boolean;
package g_package is
procedure foo (bar : String);
private
procedure quix (f : String);
quix_access : constant external.t_callback_p := quix'Access;
end g_package;
and the use the constant in the body:
external.procedure_f (quix_access);
A: There's no way to do this in Ada. If you wish to be non-portable and are using (as it appears) GNAT, you can use the GNAT-specific attribute 'Unrestricted_Access. | unknown |
