d12707 | train | I found the answer here:
If your ultimate aim is just to resign the first responder, this
should work: [self.view endEditing:YES]
The endEditing(_:) method is designed right for it
Causes the view (or one of its embedded text fields) to resign the first responder status.
A: UIViewController inherits from UIResponder so a naive way (I am pretty sure is not the smartest way to do it) would be by overwriting the following methods (at least 1 of them)
– touchesBegan:withEvent:
– touchesMoved:withEvent:
– touchesEnded:withEvent:
- touchesCancelled:withEvent:
Next you could get the touched view by doing
UITouch *touch = [touches anyObject];
UIView *touchedView = [touch view];
finally resign the first responder if that view is not your text field
if(touchedView != textField){
[textField resignFirstResponder];
}
_
Demerits of this approach:
You will have to handle the "tap" by yourself. (Same problem as the old iOS 3.1 or earlier). You will have to come up with your own implementation to differentiate single taps from drags, swipes, double taps, long taps, etc. Is not hard to get it working well but it is not likely you get it exactly the same way Apple detects taps (timings, distances, thresholds count!)
However, that depends on your needs.
If your view structure is simple enough then you could add a gesture recognizer to the container view and resign the first responder every time the handler is called :)
Hope this helps
A: Nobody has yet presented the best answer here:
[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
From the documentation on this method:
Normally, this method is invoked by a UIControl object that the user
has touched. The default implementation dispatches the action method
to the given target object or, if no target is specified, to the first
responder. Subclasses may override this method to perform special
dispatching of action messages.
I bolded the relevant part of that paragraph. By specifying nil for the to: parameter, we automatically call the given selector on the first responder, wherever it is, and we don't need to have any knowledge of where in the view hierarchy it is. This can also be used to invoke other methods on the first responder as well, not just cause it to resign first responder status.
A: -(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self.TextField resignFirstResponder];
return YES;
}
A: Give a unique Tag to your UITextfield (i.e. 333), then to resign the first responder do this:
UITextField *textField = (UITextField *)[self.view viewWithTag:333];
[textField resignFirstResponder];
A: For a more robust and clean solution add a tap gesture recognizer to your primary view.
This will work better with nested views and will be cleaner than secret buttons in code and UI builder.
In your view did load:
UITapGestureRecognizer* tapBackground = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard:)];
[tapBackground setNumberOfTapsRequired:1];
[self.view addGestureRecognizer:tapBackground];
..and define your target action to be triggered on tap:
-(void) dismissKeyboard:(id)sender
{
[self.view endEditing:YES];
}
A: The best option is the shortest way ;)
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.view endEditing:YES];
}
A: Using Swift you can do this:
func viewDidLoad() {
super.viewDidLoad()
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.hideKeyboardByTappingOutside))
self.view.addGestureRecognizer(tap)
}
@objc func hideKeyboardByTappingOutside() {
self.view.endEditing(true)
}
A: Just create an IBOutlet or pointer to the text field and call [textField resignFirstResponder]; from where ever you want.
A: UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(TapTodissmiss)];
[self.view addGestureRecognizer:tap];
and selector
-(void)TapTodissmiss{
[self.txtffld resignFirstResponder];
}
A: I am posting this as a separate answer because a lot of the other answers recommend using [textField resignFirstResponder]. This is causing an invalid capability error in Xcode 11.5 with the incomprehensible addition "Unable to insert COPY_SEND"
On a iPad with iOS 9.3.6:
2020-05-23 20:35:01.576 _BSMachError: (os/kern) invalid capability (20)
2020-05-23 20:35:01.580 _BSMachError: (os/kern) invalid name (15)
On a iPad with iPadOS 13.5:
2020-05-23 20:38:49 [Common] _BSMachError: port 12f0f; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"
On a iPhone with iOS 13.5:
2020-05-23 20:43:34 [Common] _BSMachError: port d503; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"
[textField resignFirstResponder] cannot be used anymore.
A: When possible the best option is to make your UIView to inherit from UIButton instead.
You just need to change it in Interface Builder and immediately you will get the options to create an Action "Touch Up Inside" like any other button.
Your view will work as usual because UIButton is still a view but you will get notified when someone taps on the view. There you can call
[self.view endEditing:YES];
To resign any keyboard.
Please note that if your view is an UIScrollView this solution is not for you.
A: Create your IBOutlet in ViewController.h file like below:
//YOUR ViewController.h FILE
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
{
//WIRE THIS WITH YOUR UITextField OBJECT AT YOUR .xib FILE
IBOutlet UITextField *yourIBOutletUITextField;
}
@end
Add this to your ViewController.m file:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[yourIBOutletUITextField resignFirstResponder];
}
like below:
//YOUR ViewController.m FILE
#import "ViewController.h"
@implementation ViewController
//ADD THIS METHOD BELOW
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[yourIBOutletUITextField resignFirstResponder];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
@end
A: For my implementation, [self.view endEditing:YES] did not work.
To finally make sure the keyboard was hidden, I had to make one of my views the first responder, and then immediately make it resign as per the function below:
-(void) hideKeyboardPlease{
[uiTextTo becomeFirstResponder];
[uiTextTo resignFirstResponder];
}
A: This is what I do...
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideAllKeyboards)];
tapGesture.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGesture];
-(void) hideAllKeyboards {
[textField_1 resignFirstResponder];
[textField_2 resignFirstResponder];
[textField_3 resignFirstResponder];
.
.
.
[textField_N resignFirstResponder];
}
A: This is the easiest way iv found that works consistently. Just add a tap gesture recognizer on the view and you're good to go.
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.view endEditing:YES];
}
A: Update
I found another simple way
simply declare a property :-
@property( strong , nonatomic) UITextfield *currentTextfield;
and a Tap Gesture Gecognizer:-
@property (strong , nonatomic) UITapGestureRecognizer *resignTextField;
In ViewDidLoad
_currentTextfield=[[UITextField alloc]init];
_resignTextField=[[UITapGestureRecognizer alloc]initWithTarget:@selector(tapMethod:)];
[self.view addGestureRecognizer:_resignTextField];
Implement the textfield delegate method didBeginEditing
-(void)textFieldDidBeginEditing:(UITextField *)textField{
_currentTextfield=textField;
}
Implement Your Tap Gesture Method (_resignTextField)
-(void)tapMethod:(UITapGestureRecognizer *)Gesture{
[_currentTextfield resignFirstResponder];
}
A: Create a big button behind it all, and the button's callback calls resignFirstResponder to every input you have. Just make sure to put everything that the user interacts with on top of the button.
Of course the button will be custom rect and transparent.
I would look into implementing an IBOutletCollection called resignables and set every input to that collection. And the button callback iterates over that collection calling resignFirstResponder to them all.
Edit: if it is a re-sizable scroll view, remember to correctly set the re-size markers in the button's view option, that way the button will always expand and contract to the scrollview's height and width | unknown | |
d12708 | train | You are inserting your data inside a <pre> block, effectively telling the browser not to wrap the text. I assume you do this so that literal newlines in the 'note' data are indeed printed.
To alter wrapping space-characters and newline functionality of an element, you can use the CSS white-space property. So, to get what you want (both wrapping AND literal newlines), you can set white-space to either pre-line or pre-wrap, depending on your need. Eg. change the <pre> to
...<pre style="white-space:pre-wrap;">' . base64_decode($eval['note']) . '</pre>...

This gets an incremented date value for each record which you can then check against your start and end dates.

template <typename... Args> struct Entity {

Then you can pass entity_args_t to a template that has a partial specialization for types<T...>. If you typedef the Entity, you can instead write a partial specialization for Entity<T...>, which may make more sense for your case
template <typename... Args> struct Entity {
struct Inner {
// Equivalent: typedef Entity entity_args_t;
typedef Entity<Args...> entity_args_t;

d12718 | train | The map is an array of N buckets.
The put() method starts by calling hashCode() on your key. From this hash code, it uses a modulo to get the index of the bucket in the map.
Then, it iterates through the entries stored in the linked list associated with the found bucket, and compares each entry key with your key, using the equals() method.
If one entry has a key equal to your key, its value is replaced by the new value. Else, a new entry is created with the new key and the new value, and stored in the linked list associated with the bucket.
Since Cat instances and String instances are never equal, a value associated with a String key will never be modified by putting a value associated with a Cat key.
A: It will be defined by your object.
You have to create a hashCode() and a equals() method so it can be stored in your hashtable.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
See the javadoc at java.lang.Object http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/Object.html#hashCode()
or you can read this for an explanation
http://www.javaworld.com/javaworld/javaqa/2002-06/01-qa-0621-hashtable.html
I hope it helps
A: Storing the value to HashMap depends on the hashcode() and equals() method.Please find the more reference from here.
HashMap - hashcode() Example
More information of HashMap get() retrieval of values.Here
A: When a HashMap is used, the keys in it are unique. This uniqueness of the keys is checked in Java from the definition of the equals() and hashCode() methods that the class of the objects under consideration provides.
This is done by comparing using the equals() method first and if it returns equal then comparing using hashCode().Also, you must be knowing that each reference pointing to an object has a bit pattern which may be different for multiple references referring to the same object.
Hence, once the equals() test passes, the object won't be inserted into the map since the map should have unique keys. So, each hashCode value for objects which are keys in the map will form different buckets for a range of hashCode values and the object will be grouped accordingly.
EDIT to provide an example:
For example, let us consider that two objects have a String attribute with values "hello" and "hlleo" and suppose the hashCode() function is programmed such that the hash code of an object is the sum of the ASCII values of the characters in the String attribute and the equals() method returns true if the values of the String attribute are equal.
So, in the above case, equals() return false as the strings are not equal but the hashCode will be same. So the two objects will be placed in the same hash code bucket.
Hope that helps. | unknown | |

Unfortunately, this involeves the checkBoxes that are generated by the rowSelector-option within the DataGrid-declaration. So if you dont need the rowSeletion-feature (at least by checkboxes), this works.

A: Try this maybe....
<html>

<envVariable name="NLS_CURRENCY" value="¥"/>
<envVariable name="DISPLAY" value="MyServer.MyCompany.com:0.0"/>

d12729 | train | How do you know if one car is faster than another? Drive both of them and compare the times.
Generally, databases are more efficient at joining data than in-memory Linq (due to pre-computed indices, hashes, etc.) but there certainly could be cases where in-memory would be faster. However, when you're not pulling ALL of the data into memory, the benefit of having less data over the wire might make a bigger difference than any performance improvement in joining.
So there's not a definitive answer. Start with something that works, THEN focus on performance improvements by measuring the time before and after the changes.
A: One of the slower parts of executing a database query is the transport of the data from the DBMS to your local process. Hence it is wise to limit the amount of data to be transported to your process. Only transport the data you actually plan to use.
So if you query "Teachers with their Students", you'll know that the ID of the teacher will equal the foreign key 'TeacherIdin everyStudent`. So why transport this foreign key for every of the teacher's 1000 students if you already know the value?
Another reason to let the DBMS perform the query is because the software in the database is optimized to perform queries. If the DBMS created a temporary table for a query, and it detects that a new query needs the same temporary table, a smart DBMS will reuse this temporary table, even if the query came from another process.
Smart DBMSes will detect that certain indexes are used more often than others, and keep them in memory, instead of reading them from disk all the time.
So a DBMS has all kinds of tricks to speed up the execution of queries.
You can see that this tricks help by measuring: perform a query twice in a row and see that the second query is executed faster than the first one. This effect is also a reason that you can't measure whether it is faster to let given query execute by the DBMS or to execute it in local memory., as some suggested.
The only proper method would be to measure the chosen strategy with all kinds of queries during a longer period of time (minutes, if not hours), with a lot of processes that perform these queries. One thing you'll know for certain is that executing queries AsEnumerable can't benefit from the queries executed by others. | unknown | |

d12731 | train | Use std::codecvt_facet template to perform the conversion.
You may use standard std::codecvt_byname, or a non-standard codecvt_facet implementation.

locale utf8locale(locale(), new codecvt_byname<wchar_t, char, mbstate_t> ("en_US.UTF-8"));
wcout.pubimbue(utf8locale);
wcout << L"Hello, wide to multybyte world!" << endl;
Beware that on some platforms codecvt_byname can only emit conversion only for locales that are installed in the system.
A: Well, after some testing I figured out that FILE is accepted for _iobuf (in the w*fstream constructor). So, the following code does what I need.#include <iostream>
#include <fstream>
#include <io.h>
#include <fcntl.h>
//For writing
FILE* fp;
_wfopen_s (&fp, L"utf-8_out_test.txt", L"w");
_setmode (_fileno (fp), _O_U8TEXT);
wofstream fs (fp);
fs << L"ąfl";
fclose (fp);
//And reading
FILE* fp;
_wfopen_s (&fp, L"utf-8_in_test.txt", L"r");
_setmode (_fileno (fp), _O_U8TEXT);
wifstream fs (fp);
wchar_t array[6];
fs.getline (array, 5);
wcout << array << endl;//For debug
fclose (fp);This sample reads and writes legit UTF-8 files (without BOM) in Windows compiled with Visual Studio 2k8.
Can someone give any comments about portability? Improvements?
A: The easiest way would be to do the conversion to UTF-8 yourself before trying to output. You might get some inspiration from this question: UTF8 to/from wide char conversion in STL
A:
get FILE* or integer file handle form a std::basic_*fstream?
Answered elsewhere.
A: You can't make STL to directly work with UTF-8. The basic reason is that STL indirectly forbids multi-char characters. Each character has to be one char/wchar_t.
Microsoft actually breaks the standard with their UTF-16 encoding, so maybe you can get some inspiration there. | unknown | |

d12733 | train | Simple solution: The formula needs to be a string that includes an "equals" (=) prefix.
Cell E5 presently contains a formula (=E4) which yields:
{FILTER(DBD!B2:F;LÆNGDE(DBD!B2:B)>0);FILTER(Platformen!B2:F;LÆNGDE(Platformen!B2:B)>0)
Two things to note here:
1) the content is treated as text
2) there is no "equals sign" (=) at the beginning of the string.
The content should look like this:
={FILTER(DBD!B2:F;LÆNGDE(DBD!B2:B)>0);FILTER(Platformen!B2:F;LÆNGDE(Platformen!B2:B)>0)
How to fix it
Edit Cell E5 (or Cell E4, whichever suits you) to insert an equals sign (=) to the left of the opening curly bracket. The result will still be treated as a string, so there is no danger involved ;)
One proviso: I had to convert "LÆNGDE" to "LEN" in order for my test to work. But I think this is probably just an issue of "Display Language" which, for me, is English (Australia), and for you is probably Danish. | unknown | |

Therefore, I see no advantage(s) in having a package body.
Perhaps it can be used as code graveyard - you know, there are some procedures and functions you wrote but you don't need them any more - create a package body and put all that code in there. You won't be able to use them, but will be able to have a look if necessary. Something like your own code repository stored in the database, instead of scattered all over your hard disk in different directories and different kind of files (.SQL, .PRC, .PKG, ...).
A: I think the premise of the question is misleading and probably wrong.The Interviewer perhaps wanted you to know the difference between variables and procedures that are not defined in package specification and defined and called or used internally within the package body. A package body can be used to define local procedures and variables without them having defined inside package specification.

d12736 | train | This is how position: sticky is intended to work. If you need it to also work outside the parent than you have to change the HTML structure.
See also the official definition: https://www.w3.org/TR/css-position-3/#sticky-pos
A: There is a little trick you can try.
In some cases it will break your layout and in others it won't. In my case, I have a header with some buttons but when I scroll down, I want to have access to some action buttons which are inside that one-line header. The only change is to set the display property of your parent to be inline.
.parent {
display: inline;

A: Already 7 months ago, but I found a CSS only solution if the element you want to be sticky is the last one of its parent, its very simple: Just give the parent element position: sticky; and also give it top: -xx;, depending on the height of the elements before the last one.

position: sticky;
top: -3em;

$(document).ready(function() {
// Get the current top location of the nav bar.
var stickyNavTop = $('nav').offset().top;
// Set the header's height to its current height in CSS
// If we don't do this, the content will jump suddenly when passing through stickyNavTop.
$('header').height($('header').height());
$(window).scroll(function(){
if ($(window).scrollTop() >= stickyNavTop) {
$('nav').addClass('fixed-header');
} else {
$('nav').removeClass('fixed-header');
}
});

A: Like mentioned, sticky works that way. However there is a CSS hack that you can play around with.
Disclaimer
This is an ugly hack and will probably create a lot of problems with the following content. So I would not recommend it for most usecases. Having that said...
Negative margin hack
There is a hack you could play around with including negative margin. If you extend the height of the container and then give it some negative bottom margin, it could at least "visually leave" the container.
I altered your code and created a JSFiddle for demonstration.

A: Using:
Splitter
you can split lines by delimiter then use the result to match against the dictionary. like this:
SELECT t.keywords FROM ##tablea t
CROSS APPLY (SELECT REPLACE(t.keywords, ' and ', ',')) new(kwds)
CROSS APPLY dbo.DelimitedSplit8K(new.kwds, ',') s
WHERE s.item NOT IN (SELECT keyword FROM ##dictionary)
A: Try this:
select t.*
from ##tableA t
cross join (
select max(case when id = 1 then keyword end) firstKeyword,

d12742 | train | You can use str.split:
>>> x = "hello Why You it from the"
>>> x.split()
['hello', 'Why', 'You', 'it', 'from', 'the']
>>> x = "hello Why You it from the"
>>> x.split()
['hello', 'Why', 'You', 'it', 'from', 'the']
>>>
Without any arguments, the method defaults to splitting on whitespace characters.
I just noticed that all of the strings in your example list are lowercase. If this is needed, you can call str.lower before str.split:
>>> x = "hello Why You it from the"
>>> x.lower().split()
['hello', 'why', 'you', 'it', 'from', 'the']
>>>
A: str.split() should do it:
>>> x = "hello Why You it from the"
>>> x.split()
['hello', 'Why', 'You', 'it', 'from', 'the']
If you want all lowercase (as @iCodez also points out):
>>> x.lower().split()
['hello', 'why', 'you', 'it', 'from', 'the']
From the link above:
If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.
sep is the first argument of split(). | unknown | |
d12743 | train | Given
Contact contactList[100];
int num_entries;
you can use std::sort to sort the list of contacts. std::sort has two forms. In the first form, you can use:
std::sort(contanctList, contactList+num_entries);
if you define operator< for Contact objects.
In the second form, you can use:
std::sort(contanctList, contactList+num_entries, myCompare);
if you define myCompare to be callable object that can compare two Contact objects.
To use the first form, change Contact to:
struct Contact {
string name, number, notes;
bool operator<(Contact const& rhs) const
{
return (this->name < rhs.name);
}
};
If you want to the comparison of names to be case insensitive, convert both names to either uppercase or lowercase and them compare them. | unknown | |

d12745 | train | You have done it the exact right way if there is no other endpoint available to fetch multiple post author information at a time.
Well, this is meant to be an answer, but I'd start with a question.
Do you have access to the maintainer or developer handling the Restful API endpoint you are trying to get from?
If yes?
Tell them to simply include the author information on the response for fetching the post(s)
Or simply provide you with an endpoint that allows you to get author information for many posts at a time.
If No
Go over the documentation provided (if any) and see if there is any endpoint that allows you to fetch author information for multiple posts with a single request.
If none of the above option seems to be a way, kindly remember to block the UI When fetching the resources.
You can also fetch for few authors first and display while fetching for more in the background or on request for more by user, that way you would give a better user experience.

A: Make the following changes -
*
*var {google} = require('googleapis'); instead of var google = require('googleapis');
*Write var OAuth2 = google.auth.OAuth2; instead of var googleAuth = require('google-auth-library');
*Do not npm install google-auth-library. If you did, remove it from your package.json and do npm install again.
*Make sure you have the latest version of googleapis package. If you do not - do npm install googleapis@27 to get it. (Also add it to the package.json for future).
*For any callback - instead of response.items, do response.data.items. You do not necessarily need the callback output when you create an event but you definitely need it when you list events. So do not forget to make this change there.
I don't think there would be any issue once you follow all these steps. If there still is, just reply to this. I will try my best to get it resolved! | unknown | |

d12753 | train | IE has problems with not properly encoded URLS, it has also problems with simple <a href containing unencoded chars.
LABEL%20NAME instead of LABEL NAME should work.
With JSONP, jQuery generates a <script src="http://technopress-demo.blogspot.com/feeds/posts/default/-/LABEL NAME?alt=json-in-script&max-results=5"> which has the unencoded char in it.
Instead of encodeURIComponent(LABEL NAME), use quotation marks:
encodeURIComponent("LABEL NAME")
Important: Save your files UTF-8 encoded.

d12756 | train | There are two ways you can allocate an array of strings in C.
*
*Either as a true 2D array with fixed string lengths - this is what you have currently. char strings [x][y];.
*Or as an array of pointers to strings. char* strings[x]. An item in this pointer array can be accessed through a char**, unlike the 2D array version.
The advantage of the 2D array version is faster access, but means you are stuck with pre-allocated fixed sizes. The pointer table version is typically slower but allows individual memory allocation of each string.
It's important to realise that these two forms are not directly compatible with each other. If you wish to declare a function taking these as parameters, it would typically be:
void func (size_t x, size_t y, char strings[x][y]); // accepts 2D array
void func (size_t x, size_t y, char (*strings)[y]); // equivalent, accepts 2D array
or
void func (size_t x, char* strings[x]); // accepts pointer array
void func (size_t x, char** strings); // equivalent - accepts pointer array | unknown | |

d12759 | train | There is a built-in way to get the line and column number in JavaScript, but unfortunately, it isn't supported in (literally) all browsers. The only browser that supports it is Firefox.
Right now, the best thing you can do is just get it from the browser console.
However, to get it from the Error object, you can first wrap your code in a try/catch statement.
try {
a();
} catch (err) {
console.log(err); // ReferenceError: a is...
}
Then, you can get the line and column numbers from it. Beware; it's only supported in Mozilla!
console.log(err.lineNumber, err.columnNumber); // 5 5
The only properties that aren't non-standard in the Error object is the name and message.
In conclusion, even though there is a built-in way to get the line and column number in JavaScript, it is non-standard and only supported in Firefox.
The best way to get it is to get it from the browser console (or to get it from third-party libraries, if possible). | unknown | |

In activity A you have to override onActivityResult and handle the result from activity B .
like
startActivityForResult(new Intent(this,ActivityB.class),123);
@Override
public void onActivityResult(int requestCode, int resultCode, Intentdata) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode==123)
{
String sordData= data.getStringExtra("sortOrder","byName")
sortYourDAta(sordData);
}
}
}
and in activity b when sort order is selected
just store value in a variable sortOrder="byDate";
and onbackpressed or when ever you want to go back just call this
setResult(123,new Intent().putExtra("sortOrder",sortOrder));

d12765 | train | After uploading the file have to be displayed in the list of static files. The list of files have a column Reference, which contain a string like this: #APP_IMAGES#test.css. Copy this string and put it, for example, on the page in the section CSS - File URLs. This should work.
Then make sure that file reference works. Open your page and take a look on a list of CSS files. The same functionality is present in all browsers, but it is accessible by different ways. In IE:
*
*Press F12.
*Open Network tab.
*Press "Enable network traffic capturing" (a green triangle in the left top corner).
*Reload the page. A list of files appears.
*Find your file in a list:
*
*If the file is not present, then you copied an incorrect link, or you copied it into an incorrect place, etc.
*If the file is present, normally it should have status 200 (the Result column). If a status is not 200, there could be a lot of reasons (depending on the status).
*If the file is present with the status 200, your CSS property doesn't work, because it is overridden with another CSS. To define with which one, go to the Dom Explorer tab.
A: You can try this approach:
*
*On server, go to ORACHE_HOME/apex/images/css (path can be different, but you can find it by .css extension)
*Put you file here
*Id editor, in page properties, go to the CSS -> File URLs section

d12767 | train | Few thoughts that might be useful for you:
First of all you can get rid of first $sort as you have another one in the last pipeline stage and that one will guarantee right order.
There are few ways how to replace $lookup + $unwind + $match + $project + $group.
You can use $addFields with $filter to filter out some elements before you $unwind:
{
$lookup: {
from: 'products',
localField: 'product',
foreignField: '_id',
as: 'productModel',
}
},
{
$addFields: {
productModel: {
$filter: {
input: '$productModel',
as: 'model',
cond: { $ne: [ '$$model.archived', true ] }
}
}
}
},
{
$unwind: '$productModel'
}
In this case you can remove $match since this operation is performed in nested array.
Second way might be to use $lookup with custom pipeline, so that you can perform this additional filtering inside $lookup:
{
$lookup: {
from: 'products',
let: { productId: "$product" },
pipeline: [
{
$match: { $expr: { $and: [ { $eq: [ "$$productId", "$_id" ] }, { $ne: [ "$archived", true ] } ] } }
}
],
as: 'productModel',
}
}
As another optimization in both cases you don't need $unwind as your productModel array is filtered and then you can just modify your $group:
{
$group: {
_id: '$product',
saleModelsCount: { $sum: { $size: "$productModel" } },
quantity : { $sum: '$quantity' },
}

const [key, index] = combo.split('_');
acc[index] = { ...acc[index], [key]: value };

d12769 | train | You are misunderstanding object files. Start by taking a look at this question:
What does an object file contain?
Object files do contain binary machine language instructions for the target platform, so there is no "translator" of any kind between the binary code contained in them and what is executed on the target CPU.
I think your confusion stems from the fact that object files also contain other information, such as symbol tables and constants. It is the linker's job to collect all of this information and package it into an executable.
Side Note: This answer is assuming a C/C++ perspective. Languages like Java that execute on a virtual machine have other layers in between compiling and execution. | unknown | |
d12770 | train | Without a good, minimal, complete code example, it's impossible to know for sure what the best approach is.
However, if you have set your ListView up correctly and the ItemsSource is a collection of Discussion objects, then by default the SelectedValue property will return the Discussion object instance reference that corresponds to the selected item in the list.
In that case, you would just change your code to look like this:
private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
DependencyObject clickedObj = (DependencyObject)e.OriginalSource;
while (clickedObj != null && clickedObj != listDiscussion)
{
if (clickedObj.GetType() == typeof(ListViewItem))
{
Discussion selectedDiscussion = (Discussion)listDiscussion.SelectedValue;
this.NavigationService.Navigate(new MessagePage(selectedDiscussion));
break;
}
clickedObj = VisualTreeHelper.GetParent(clickedObj);
}
}
I.e. just use the SelectedValue property instead of SelectedItem. If you have deviated from the default by setting the SelectedValuePath property, then you will want to use the ItemContainerGenerator object to get the correct reference:
private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
DependencyObject clickedObj = (DependencyObject)e.OriginalSource;
while (clickedObj != null && clickedObj != listDiscussion)
{
if (clickedObj.GetType() == typeof(ListViewItem))
{
Discussion selectedDiscussion =
(Discussion)listDiscussion.ItemContainerGenerator
.ItemFromContainer((ListViewItem)listDiscussion.SelectedItem);
this.NavigationService.Navigate(new MessagePage(selectedDiscussion));
break;
}
clickedObj = VisualTreeHelper.GetParent(clickedObj);

d12771 | train | I think you have the right idea. You will want to keep the old fields together with their field numbers unchanged as long as there is data stored in the old format. One of the great things about protocol buffers is that unset fields are essentially free, so you can add as many new fields as you want to facilitate the migration.
What I would do is add a new set of float fields and rename the double fields while preserving their field numbers:
message Matrix {
// Values in these fields should be transitioned to floats
double deprecated_width = 1;
double deprecated_height = 2;
repeated double deprecated_entries = 3;
float width = 4;
float height = 5;
repeated float entries = 6;
}
Whenever you read a Matrix from persistent storage move any values from the deprecated fields to the non-deprecated fields and write back the result. This should facilitate incremental migration to floats.
I will mention one more thing that you probably already know: protocol buffers don't care about the fields names. Only field numbers matter for serialization and deserialization. This means fields can be renamed freely as long as the code that manipulates them is likewise updated.
At some point in the future when the migration has been completed remove the migration code and delete the deprecated fields but reserve their field numbers:
message Matrix {
reserved 1, 2, 3;
float width = 4;
float height = 5;
repeated float entries = 6;
}
This ensures any stray messages in the old format blow up on deserialization instead of cause data corruption.
Hope this helps! | unknown | |
d12772 | train | Stackoverflows rarely happen with typical streams; without code I can't be sure what's wrong.
In earlier versions of RxJava, there were reentrancy problems in some operators that could result in StackOverflows but we haven't received any bug reports like it in some time now. Please make sure you are using the latest RxJava from the 1.x line (the RxAndroid plugin's dependency may need overriding as it is infrequently updated in this regard).
There are a few things you can do:
*
*compact subsequent doOnNext and doOnError calls into doOnEach
*add observeOn(Schedulers.computation()) occasionally
*avoid chaining too many mergeWiths, collect up sources into a List and use merge(Iterable)
*upgrade to RxJava 2.x which should have less stack depth (have not verified)
Edit:
Based on the stacktrace, my undestanding is that you have too many empty sequences and switchIfEmpty keeps deepening the stack when switching from one empty sequence to the next. As you found out, subscribeOn helps "restart" the stack. I'll investigate possible resolutions within RxJava itself.
A: The cause of this problem was Jack compiler (https://source.android.com/source/jack.html) which I use in the project for lambdas support. I switched it off and now everything works fine | unknown | |
d12773 | train | I do not know Epics, but I think I can give you some hints about how to address this problem.
Let's start from the fact that you have an array of ids, assetIds, and you want to make an http call for each id with a controlled level of concurrency, maxParallelQueries.
In this case from function and mergeMap operator are yor friends.
What you need to do is
// from function transform an array of values, in this case, to a stream of values
from(assetIds).pipe(
mergeMap(id => {
// do whatever you need to do and eventually return an Observable
return AssetDataService.fetchThumbnailData(id)
}, maxParallelQueries) // the second parameter of mergeMap is the concurrency
)
In this way you should be able to invoke the http calls keeping the limit of concurrency you have established
A:
*
*I am able to get the batch based response in next method of subscribe. However, the action invoked in this function along with response is not getting invoked.
You mustn't call an action imperatively in redux-observable. Instead you need to queue them.
actions.AssetActions.receivedThumbnailsAction(response, meta) would return an plain object of the shape {type: "MY_ACTION", payload: ...} instead of dispatching an action. You rather want to return that object wrapped inside an observable inside mergeMap in order to add the next action to the queue. (see solution below)
*maxParallelQueries dont seems to be working as intended. All the fetchThumbnailObservables() are executed at once and not in the batches of 3 as set as constant/
First guess: What is the return type of AssetDataService.fetchThumbnailData(assetIds.slice(count, count + batchSize))? If it is of type Promise then maxParallelQueries has no effect because promises are eager and start immediately when created thus before mergeMap has the chance to control the request. So make sure that fetchThumbnailData returns an observable. Use defer rather than from if you need to convert a Promise to an Observable to make sure that a promise is not being fired prematurely inside fetchThumbnailData.
Second guess: forkJoin is firing all the request so mergeMap doesn't even have the chance to restrict the number of parallel queries. I'm surprised that typescript doesn't warn you here about the incorrect return type in mergeMap(fetchThumbnailObservable => fetchThumbnailObservable, ...). My solution below replaces forJoin with from and should enable your maxParallelQueries.
*How to handle return of observable so that mergeMap do not give syntax error . Argument of type '({ payload }: IAction) => void' is not assignable to parameter of type '(value: IAction, index: number) => ObservableInput'. Type 'void' is not assignable to type 'ObservableInput'.ts(2345)
This is not a syntax error. In an epic you have either the option to return an empty observable return empty() if no subsequent actions are intended or dispatch another action by returning an observable of type IAction. Here my (untested) attempt to meet your requirements:
const getThumbnails: Epic<IAction, IAction, IStoreState> = (action$, state$) =>
action$.ofType(ActionTypes.AssetActions.DATA.FETCH_THUMBNAILS).pipe(
mergeMap( ({ payload }) => {
const assetIds = Object.keys(payload);
const meta = payload;
const batchSize = 10;
const maxParallelQueries = 3;
const fetchThumbnailObservables : Observable<IThumbnailResponse>[] = [];
for (let count = 0; count < assetIds.length; count += batchSize) {
fetchThumbnailObservables.push(
AssetDataService.fetchThumbnailData(
assetIds.slice(count, count + batchSize)
)
);
}
return from(fetchThumbnailObservables)
.pipe(
mergeMap(
fetchThumbnailObservable => fetchThumbnailObservable,
maxParallelQueries
),
map((response) =>
// dispatch action for each response
actions.AssetActions.receivedThumbnailsAction(response, meta)
),
// catch error early so epic continue on error
catchError((error) => of(actions.Common.errorOccured({ error })))
);
})
);
Please notice that I moved catchError closer to the request (inside the inner forkJoin Observable) so that the epic does not get terminated when an error occurs. Error Handling - redux observable This is so because when catchError is active it replaces the failed observable with the one that is returned by catchError. And I assume you don't want to replace the whole epic in case of an error?
And one thing: redux-observable handles the subscriptions for you so won't need to call .subscribe or .unsubscribe anywhere in your application. You just need to care a about the lifecycle of observables. Most important to know here is when does an observable start, what happens to it when it completes, when does it complete or what happens when an observable throws. | unknown | |
d12774 | train | Some problems with that code:
*
*Select Case Range(Target.Address) doesn't make sense - it takes the Target range, takes its address and creates a range from that address, which points to the original Target range, and finally VB takes the default property of that range, because its not being used in an object reference context. So the whole thing should be replaced with Target.Value.
*Later same thing happens to minhaCelula.
*Code under "C" and "P" is the same and should be placed under the same Case branch.
*Colons are not used in VB's Select Case.
*AddComment should be called without parentheses. Even better, you should benefit from the fact AddComment returns the reference to the added comment, so you can directly use that (in which case you must keep the parentheses).
So that should be rewriteen as:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Me.Range("A1:S1000"), Target) Is Nothing Then
Select Case Target.Value
Case "C", "P"
Target.AddComment("").Visible = True
End Select
End If
End Sub
As for the question, when you use Comment.Visible, Excel stops managing the comment's visibility. To leave the management on Excel side, make the comment's shape visible instead:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Me.Range("A1:S1000"), Target) Is Nothing Then
Select Case Target.Value
Case "C", "P"
With Target.AddComment("").Shape
.Visible = msoTrue
.Select
End With
End Select
End If

d12777 | train | (3,) does not mean the 3 is first. It is simply the Python way of writing a 1-element tuple. If the shape were a list instead, it would be [3].
(, 3) is not valid Python. The syntax for a 1-element tuple is (element,).
The reason it can't be just (3) is that Python simply views the parentheses as a grouping construct, meaning (3) is interpreted as 3, an integer.
A: As you know, numpy arrays are n-dimensional. The shape tells dimensions in the order. If it is 1-D you will see only 1st dimension, 2-D only 2 dimensions and so on.
Here x is a 2-D array while v is a 1-D array (aka vector). That is why when you do shape on v you see (3,) meaning it has only one dimension whereas x.shape gives (4,3). When you transpose v, then that is also a 1-D array. To understand this better, try another example. Create a 3-D array.

d12779 | train | In general, I think it is not a good idea to try to emulate Haskell patterns in F#. In Haskell, lot of code is written as very generic, because monads and applicatives are used more frequently.
In F#, I prefer writing more specialized code, because you do not need to write code polymorphic over monads or applicatives and it just makes it easier to see what is going on. So, I do not think I would ever want to write <*> operator that works over any "applicative" in practice in F#.
That said, the issue with your code is that the <*> operator uses the same ^A type parameter for both arguments and the result (while they are different types in the call) - if you use three separate type parameters it works fine:
let inline (<*>) (f: ^B) (t:^A) : ^C =
let apply' = (^A : (member apply : ^B -> ^C) (t, f))

JSFiddle
A: I made a fiddle with a solution
http://jsfiddle.net/Jarga/hg45z9rL/
Clicking "Update" will display the current knockout model as text below the button.
What was missing was the linking the change of the textbox to the observable by adding a listener in the render function. Also each row's textbox was being given the same id, which is not a good idea either. (Note: the event aliases are just to prevent collision with other handlers)
Changing the render function to build useful ids and adding the following should work:
$('#' + id).off('change.grid')
$('#' + id).on('change.grid', function() {
row.age($(this).val());
});
Ideally Knockout would handle this for you but since you are not calling applyBindings nor creating the data-bind attributes for the html elements all that knockout really gives you here is the observable pattern.
Edit: Additional Solution
Looking into it a little bit more you can let Knockout handle the rendering by adding the data-bindattribute into the template and binding your knockout model to the table element.
var html = '<div style="display:inline-flex">' +
'<input type="text" class="headerStyle h5Style" id="' + id + '" data-bind="value: $data[' + cell.row + '].age"/>'
And
ko.applyBindings(people, document.getElementById("example"));
This removes the whole custom subscription call when constructing the Personobject as well.
Here is another fiddle with the 2nd solution:
http://jsfiddle.net/Jarga/a1gedjaa/
I feel like this simplifies the solution. However, i do not know how efficient it performs nor have i tested it with paging so additional work may need to be done. With this method the mRender function is never re-executed and the DOM manipulation for the input is done entirely with knockout.
A: Here is a simple workaround that re-binds the data in knockout and then destroys/recreates the datatable:
// Here's my data model
var ViewModel = function() {
this.rows = ko.observable(null);
this.datatableinstance = null;
this.initArray = function() {
var rowsource1 = [
{ "firstName" : "John",
"lastName" : "Doe",
"age" : 23 },
{ "firstName" : "Mary",
"lastName" : "Smith",
"age" : 32 }
];
this.redraw(rowsource1);
}
this.swapArray = function() {
var rowsource2 = [
{ "firstName" : "James",
"lastName" : "Doe",
"age" : 23 },
{ "firstName" : "Alice",
"lastName" : "Smith",
"age" : 32 },
{ "firstName" : "Doug",
"lastName" : "Murphy",
"age" : 40 }
];
this.redraw(rowsource2);
}
this.redraw = function(rowsource) {
this.rows(rowsource);
var options = { paging: false, "order": [[0, "desc"]], "searching":true };
var datatablescontainer = $('#datatablescontainer');
var html = $('#datatableshidden').html();
//Destroy datatable
if (this.datatableinstance) {
this.datatableinstance.destroy();
datatablescontainer.empty();
}
//Recreate datatable
datatablescontainer.html(html);
this.datatableinstance = datatablescontainer.find('table.datatable').DataTable(options);

d12788 | train | You are describing the behavior of a dynamic array.
The easiest way to implement this data structure is to create a new array once the array is full or below some threshold (only 1/4 of the cells are occupied, for example), and copy existing values into the new array.
If you want to know how it is done in java, and what optimizations are being made - you might want to have a look on the ArrayList class source.
A: You can read the source for ArrayList here: SOURCE
And you are right, it keeps an array and replaces it as needed to allow room for more objects. But it also stores the length so the array can be longer than is needed. That allows the ArrayList to grow a little without having to re-create the actual array everytime. If the ArrayList gets smaller, it doesn't have to re-create. It just changes the length as stored.
You can read the code to see how they decide when to change the array itself. Whenever they do that, they have to copy the old one's contents over.
You are right, BTW, that the old arrays get garbage collected as long as there are not variables referencing them. It sort of depends on how your code works. If that code you show and the definition is the only reference, then it will get GC'ed when you make a new array and store it.
A: The official implementation of ArrayList never reduces the size of an array, only increases the capacity when needed.
When an element is removed from the ArrayList, it ensures that the posterior elements return one position and sets null for the free element on the right. | unknown | |

d12791 | train | In the way malloc() request memory from heap, there are system calls (for e.g. shmget()) to request/create shared memory segment. If your request is successful, you can copy whatever you like over there. (Yes, you can use memcpy.) But remember to be careful about pointers, a pointer valid for one process, kept in its shared memory, is not necessarily valid for another process using that shared memory segment.
The shared memory is accessible to all processes for reading and/or writing. If multiple processes are reading/writing to a shared memory segment, then, needless to say, some synchronization techniques (for e.g. semaphore) need to be applied.
Please read up on shared memory. An excellent source is "The Linux Programming Interface" by Michael Kerrisk.

d12792 | train | A = clientA
config!B:B = clientB
In a "summary" sheet, I need to add a dropdown in column C depending on the column A
For example summary!A2 contains "client A" so the dropdown in summary!C2 will show the list of clientA
And summary!A3 contains "client B" so the dropdown in summary!C3 will show the list of clientB
What I currently do is named the range each in the "config" then in "summary" I put the Data Validation for the specific name.
I was wondering if there's a custom formula that I can put in the Data Validation for Column C that depends on the value in column A. The only challenge is there are spaces so in the Named Range I remove the space. And since it depends on the column, the row number is moving.
Looking for a formula since I am avoiding App Script for this specific file. Thanks
Hopefully someone could help me on this.
Thanks much.
You are all awesome!
A: What you can do is set an Auxiliary sheet (or extra columns far in "Summary"). You can set Summary!C2 the next Data Validation:
=Auxiliary!A1:1
Open the settings of that data validation and make sure there are no anchors (no $, for example A$1). If there is some, delete them
Close it and then copy and paste special - Data Validation only to the rest of the cells
This way C2 will be associated with row 2 from Auxiliary, C3 with row 3 and so on
Then, you can go to Auxiliary and set a formula in each row to filter the values according to B2, B3 (or however you identify the client... (a Query, or Filter) --> You'll probably need to transpose the information, so the list becomes a row
With that done, each data validation will depend now on the value of that row
Re-reading your example, you can do the same but instead of filter you can transpose the entire Config sheet and you'll have a row per client

d12794 | train | Your best performance will be if you can encode your "tests" into the SQL logic itself, so you can boil everything down to a handful of UPDATE statements. Or at least get as many as possible done that way, so that fewer rows need to be updated individually.
For example:
UPDATE tablename set firstname = [some logic]
WHERE [logic that identifies which rows need the firstname updated];
You don't describe much about your tests, so it's hard to be sure. But you can typically get quite a lot of logic into your WHERE clause with a little bit of work.
Another option would be to put your logic into a stored procedure. You'll still be doing 350,000 updates, but at least they aren't all "going over the wire". I would use this only as a last resort, though; business logic should be kept in the application layer whenever possible, and stored procedures make your application less portable.
A: SQL #1: CREATE TABLE t with whatever columns you might need to change. Make all of them NULL (as opposed to NOT NULL).
SQL #2: Do a bulk INSERT (or LOAD DATA) of all the changes needed. Eg, if changing only first_name, fill in id and first_name, but have the other columns NULL.
SQL #3-14:
UPDATE real_table
JOIN t ON t.id = real_table.id
SET real_table.first_name = t.first_name
WHERE t.first_name IS NOT NULL;
# ditto for each other column.
All SQLs except #1 will be time-consuming. And, since UPDATE needs to build a undo log, it could timeout or otherwise be problematical. See a discussion of chunking if necessary.
If necessary, use functions such as COALESCE(), GREATEST(), IFNULL(), etc.
Mass UPDATEs usually imply poor schema design.

d12795 | train | I guess that your jar file generated with Ant does not have jar-in-jar-loader, that's why it is not able to find classes inside embedded jars.
When you generate JAR with Eclipse you can Save Ant script, then jar-in-jar-loader.zip file would be added to project. Then use generated Ant file to create your JAR. This approach works for me.
Your Ant script should look like this:
<jar destfile="C:\Users\\workspace\Your.jar">
<manifest>
<attribute name="Main-Class" value="org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader"/>
<attribute name="Rsrc-Main-Class" value="org.mypackage.MainClass"/>
<attribute name="Class-Path" value="."/>
<attribute name="Rsrc-Class-Path" value="./ libA.jar "/>
</manifest>
<zipfileset src="jar-in-jar-loader.zip"/>
<fileset dir="${ProjectPath}/bin"/>
<zipfileset dir="${ProjectPath}\lib" includes="libA.jar"/>
</jar>
First zipfileset would include jar-in-jar-loader.zip
fileset would add all your classes
Second zipfileset would add libA.jar as embedded jar and same should be mentioned in Rsrc-Class-Path
A: With your Ant-generated Manifest, it is looking for the library jar files outside of the main jar file, the Eclipse one uses a special Main-Class and class loader to get to the bundled dependencies.
You probably want to use the OneJar ant task (or something similar) to achieve something comparable to what Eclipse does. | unknown | |
d12796 | train | Ideally, it should hardly matter to you. But I see the arrow in my code base for the functions implemented outside the class-declaration (i.e. into implementation file). All inline methods are shown without the arrow symbol.
I am not sure why they are duplicated in your case. May be namespace implementation has something to do.
But, again - why does it matter? | unknown | |
d12797 | train | I think the problem with Collections.shuffle() is that is uses default Random instance which is a thread-safe singleton. You say that your program is multi-threaded, so I can imagine synchronization in Random being a bottle-neck.
If you are happily running on Java 7, simply use ThreadLocalRandom. Look carefully, there is a version of shuffle() taking Random instance explicitly:
Collections.shuffle(arr, threadLocalRandom);
where threadLocalRandom is created only once.
On Java 6 you can simply create a single instance of Random once per thread. Note that you shouldn't create a new instance of Random per run, unless you can provide random seed every time.
A: Part of the problem might be the overhead of the Integer boxing and unboxing. You might find it helpful to reimplement the Fisher-Yates shuffle directly on an int[].
A: My approach woul be to generate the numbers with the Math.random() method as in the example here and initialize the list via a static init block like this:
private static List<int> list = new ArrayList<int>();
static {
for(int i = 0; i < 100; i++) {
// randomize number
list.add(number);
}
}
Hope this helped, have Fun!
A: To shuffle an array a of n elements (indices 0..n-1):
for i from n − 1 downto 1 do
j ← random integer with 0 ≤ j ≤ i
exchange a[j] and a[i]

d12798 | train | Should I be doing this at all, and / or is it the best way to do this?
Use XMVECTOR instead of XMFLOAT3 since most of the functions in DriectXMath use XMVECTOR. thus you can avoid the boring type cast and make your code clean.
I was able to use the + operator on D3DXVECTOR3, but now not XMFLOAT3?
How do I add these together?
Again, use XMVECTOR instead of XMFLOAT3
XMVECTOR also has some disadvantage(I mean the code seems a little complicated sometimes). with D3DXVECTOR3, you can simply initialize a variable as D3DXVECTOR3 a(x, y, z, w) and get it's component as a.x, a.y, ... but XMVECTOR use a different way.
To initialize an XMVECTOR, use XMVectorSet function.
XMVECTOR lookAt = XMVectorSet(x, y, z, w);
To get component of an XMVECTOR, use the following functions.
*
*XMVectorGetX
*XMVectorGetY
*XMVectorGetZ
*XMVectorGetW
A: 1. Should I?
Should I be doing this at all, and / or is it the best way to do this?
Generally speaking, you use Windows SDK to write your new code, but you don't have to convert any old code (yours or, especially, others). It`s just a waste of time. You can install DirectX SDK to be able to build it.
On the other hand, it is a good opportunity to learn a little more about DrectX and its infrastructure. For example, portng from D3DXMath to DirectXMath (previously XMMath), you will learn pros and cons of SSE-based math libraries, and it is a good place to begin to write your own.
2. How to?
If you really decided to do this hard work, then 90% of info you will find in a good article by Chuck Walbourn - MSFT:
Living without D3DX.
Another 9.9% you will figure out by yourself from documentation, and 0.1% more from looking at DirectXMath source code (it is a header library, all functions inlined and you cann freely learn them).
You will, probably, also interested in another articles by that guy on MSDN.
3. operator+ problem
Instead of single D3DXVECTORn type (where n is a number of components), new math contains two types: XMFLOATn and XMVECTOR. Same for matrices: XMMATRIX and XMFLOATaXb (where a and b is a dimensions of matrix).
*
*XMFLOAT folks are to be used to just store values. It is just a plain floats. No operators defined for them and no functions, except XMLoad*/XMStore* accept them.
*XMVECTOR and XMMATRIX is a work horses: they used in all functions and also have overloaded operators (which is not recommended to use. Use XM* functions instead). They use supersonic speed SSE internals. But.. it is a hard to use it to store values. For example, you will have alignment problems if you make XMVECTOR class member.
*So, basically, you store and moving around your values in XMFLOATs, but before any calculations, you transform them to XMVECTOR and XMMATRIX, using XMLoad* functions (as you've done with XMVector3TransformCoord()), and after calculations, you transform them back to XMFLOATs, using XMStore* functions. Or you can gain a little more profit, by aligning properly your classes and structs, so you can store XMVECTOR and XMMATRIX directly (probably, you will need aligned memory allocator).
Well, now you are ready to go. Happy porting! =) | unknown | |

d12800 | train | I faced the same problem before, and it was not because of Json. It was because of sending too much requests to google in a period. So I just slow down the frequency of sending post to Google, and never seen this message again.
A: what @ohyes means is that you send multiple (too much) requests to google using your API key in too short of a time (for example, over 100 in a minute - just an example).
for that you are receiving the OVER_QUERY_LIMIT and the empty JSON array
while you should consider changing the time between the requests, you should also verify that the array received in fact has any elements
try
{
// Tranform the string into a json object
final JSONObject json = new JSONObject(result);
JSONArray routeArray = json.getJSONArray("routes");
if(routeArray.size() > 0) {
JSONObject routes = routeArray.getJSONObject(0);
JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
encodedString = overviewPolylines.getString("points");
List<LatLng> list = decodePoly(encodedString);
}
} catch (JSONException e)
{
e.printStackTrace();
}
That would solve the exception being thrown, but it won't solve the fact that you are getting no result, probably because of the too much requests
EDIT:
The OVER_QUERY_LIMIT thing happens (probably) because of too fast calls to getJSONFromUrl() function. Please add the code that makes these calls so we could try and be more helpful on that.
Probably 500 ms delay is not enough (I'm assuming you're doing this on a background thread and not Sleeping the UI thread as this is a bad habbit). try increasing the delay to something very high, such as a minute (60000 ms) and see if this helps. If it does, lower that number to the lowest one that works.
And add the code please. | unknown |
