The entity type 'DisplayFormatAttribute' requires a primary key to be defined.
In my case I figured out the problem was that I used properties like this:
public string LastName { get; set; } //OK
public string Address { get; set; } //OK
public string State { get; set; } //OK
public int? Zip { get; set; } //OK
public EmailAddressAttribute Email { get; set; } // NOT OK
public PhoneAttribute PhoneNumber { get; set; } // NOT OK
Not sure if there is a better way to solve it but I changed the Email and PhoneNumber attribute to a string. Problem solved.
Make sure to add the protocol UICollectionViewDelegateFlowLayout
in your class
declaration
class MyCollectionViewController: UICollectionViewController, UICollectionViewDelegateFlowLayout
{
//MARK: - UICollectionViewDelegateFlowLayout
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
{
return CGSize(width: 100.0, height: 100.0)
}
}
UICollectionView implementation is quite interesting. You can use the simple source code and watch a video tutorial using these links :
https://github.com/Ady901/Demo02CollectionView.git
https://www.youtube.com/watch?v=5SrgvZF67Yw
extension ViewController : UICollectionViewDataSource {
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return nameArr.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "DummyCollectionCell", for: indexPath) as! DummyCollectionCell
cell.titleLabel.text = nameArr[indexPath.row]
cell.userImageView.backgroundColor = .blue
return cell
}
}
extension ViewController : UICollectionViewDelegate {
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let alert = UIAlertController(title: "Hi", message: "\(nameArr[indexPath.row])", preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
}
}
For Swift 3 and XCode 8, this worked. Follow below steps to achieve this:-
viewDidLoad()
{
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
var width = UIScreen.main.bounds.width
layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
width = width - 10
layout.itemSize = CGSize(width: width / 2, height: width / 2)
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0
collectionView!.collectionViewLayout = layout
}
I followed the steps mentioned in this SO and everything is fine except when my Collection View has less data (text) to make it wide enough. Checking the documentation in systemLyaoutSizeFittingSize
, I have this solution so my cell take up the width as I requested:
- (CGSize)calculateSizeForSizingCell:(UICollectionViewCell *)sizingCell width:(CGFloat)width {
CGRect frame = sizingCell.frame;
frame.size.width = width;
sizingCell.frame = frame;
[sizingCell setNeedsLayout];
[sizingCell layoutIfNeeded];
CGSize size = [sizingCell systemLayoutSizeFittingSize:UILayoutFittingCompressedSize
withHorizontalFittingPriority:UILayoutPriorityRequired
verticalFittingPriority:UILayoutPriorityFittingSizeLevel];
return size;
}
Hope this would help someone.
- (CGSize)systemLayoutSizeFittingSize:(CGSize)targetSize NS_AVAILABLE_IOS(6_0);
Apple doc:
Equivalent to sending -systemLayoutSizeFittingSize:withHorizontalFittingPriority:verticalFittingPriority: with UILayoutPriorityFittingSizeLevel for both priorities.
While the default value is "pretty low" according to Apple's doc:
When you send -[UIView systemLayoutSizeFittingSize:], the size fitting most closely to the target size (the argument) is computed. UILayoutPriorityFittingSizeLevel is the priority level with which the view wants to conform to the target size in that computation. It's quite low. It is generally not appropriate to make a constraint at exactly this priority. You want to be higher or lower.
So my change of default behavior is to enforce the width (horizontal fitting) with UILayoutPriorityRequired
.
It's Simple in Swift . just put this color in your background view color and it will work .
let dimAlphaRedColor = UIColor.redColor().colorWithAlphaComponent(0.7)
yourView.backGroundColor = dimAlphaRedColor
Add flowLayout on viewDidLoad()
override func viewDidLoad() {
super.viewDidLoad()
if let flowLayout = infoCollection.collectionViewLayout as? UICollectionViewFlowLayout {
flowLayout.estimatedItemSize = CGSize(width: 1, height:1)
}
}
Also, set an UIView as mainContainer for your cell and add all required views inside it.
Refer to this awesome, mind-blowing tutorial for further reference: UICollectionView with autosizing cell using autolayout in iOS 9 & 10
Check if the cell is being registered with self.collectionView.registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
. If so, then remove that line of code.
See this answer for more info: Why is UICollectionViewCell's outlet nil?
"If you are using a storyboard you don't want to call this. It will overwrite what you have in your storyboard."
OK, so I found the solution here: targetContentOffsetForProposedContentOffset:withScrollingVelocity without subclassing UICollectionViewFlowLayout
I should have searched for targetContentOffsetForProposedContentOffset
in the begining.
What about using UIPageViewController
with an array of UICollectionViewControllers
? You'd have to fetch proper number of items in each UICollectionViewController
, but it shouldn't be hard. You'd get exactly the same look as the Springboard has.
I've thought about this and in my opinion you have to set:
self.collectionView.pagingEnabled = YES;
and create your own collection view layout by subclassing UICollectionViewLayout
. From the custom layout object you can access self.collectionView
, so you'll know what is the size of the collection view's frame
, numberOfSections
and numberOfItemsInSection:
. With that information you can calculate cells' frames
(in prepareLayout
) and collectionViewContentSize
. Here're some articles about creating custom layouts:
You can do this (or an approximation of it) without creating the custom layout. Add UIScrollView
in the blank view, set paging enabled in it. In the scroll view add the a collection view. Then add to it a width constraint, check in code how many items you have and set its constant
to the correct value, e.g. (self.view.frame.size.width * numOfScreens)
. Here's how it looks (numbers on cells show the indexPath.row
): https://www.dropbox.com/s/ss4jdbvr511azxz/collection_view.mov If you're not satisfied with the way cells are ordered, then I'm afraid you'd have to go with 1. or 2.
converting @Anthony's answer to Swift 3.0 worked perfectly for me:
func scrollViewDidScroll(_ scrollView: UIScrollView) {
var visibleRect = CGRect()
visibleRect.origin = yourCollectionView.contentOffset
visibleRect.size = yourCollectionView.bounds.size
let visiblePoint = CGPoint(x: CGFloat(visibleRect.midX), y: CGFloat(visibleRect.midY))
let visibleIndexPath: IndexPath? = yourCollectionView.indexPathForItem(at: visiblePoint)
print("Visible cell's index is : \(visibleIndexPath?.row)!")
}

Previous versions did not really work with sections > 1. So my solution was found here https://codentrick.com/create-a-tag-flow-layout-with-uicollectionview/. For the lazy ones:
override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
let attributesForElementsInRect = super.layoutAttributesForElements(in: rect)
var newAttributesForElementsInRect = [UICollectionViewLayoutAttributes]()
// use a value to keep track of left margin
var leftMargin: CGFloat = 0.0;
for attributes in attributesForElementsInRect! {
let refAttributes = attributes
// assign value if next row
if (refAttributes.frame.origin.x == self.sectionInset.left) {
leftMargin = self.sectionInset.left
} else {
// set x position of attributes to current margin
var newLeftAlignedFrame = refAttributes.frame
newLeftAlignedFrame.origin.x = leftMargin
refAttributes.frame = newLeftAlignedFrame
}
// calculate new value for current margin
leftMargin += refAttributes.frame.size.width + 10
newAttributesForElementsInRect.append(refAttributes)
}
return newAttributesForElementsInRect
}
I've found that scrolling in viewWillAppear
may not work reliably because the collection view hasn't finished it's layout yet; you may scroll to the wrong item.
I've also found that scrolling in viewDidAppear
will cause a momentary flash of the unscrolled view to be visible.
And, if you scroll every time through viewDidLayoutSubviews
, the user won't be able to manually scroll because some collection layouts cause subview layout every time you scroll.
Here's what I found works reliably:
Objective C :
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
// If we haven't done the initial scroll, do it once.
if (!self.initialScrollDone) {
self.initialScrollDone = YES;
[self.collectionView scrollToItemAtIndexPath:self.myInitialIndexPath
atScrollPosition:UICollectionViewScrollPositionRight animated:NO];
}
}
Swift :
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
if (!self.initialScrollDone) {
self.initialScrollDone = true
self.testNameCollectionView.scrollToItem(at:selectedIndexPath, at: .centeredHorizontally, animated: true)
}
}
In your custom cell create public method:
- (void)showSelection:(BOOL)selection
{
self.contentView.backgroundColor = selection ? [UIColor blueColor] : [UIColor white];
}
Also write redefenition of -prepareForReuse cell method:
- (void)prepareForReuse
{
[self showSelection:NO];
[super prepareForReuse];
}
And in your ViewController you should have _selectedIndexPath variable, which defined in -didSelectItemAtIndexPath and nullified in -didDeselectItemAtIndexPath
NSIndexPath *_selectedIndexPath;
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"Cell";
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
if (_selectedIndexPath) {
[cell showSelection:[indexPath isEqual:_selectedIndexPath]];
}
}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];
[cell showSelection:![indexPath isEqual:_selectedIndexPath]];// on/off selection
_selectedIndexPath = [indexPath isEqual:_selectedIndexPath] ? nil : indexPath;
}
- (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];
[cell showSelection:NO];
_selectedIndexPath = nil;
}
Updated to Swift 5+ iOS 13
Collectionview Estimate Size must be none
Declare margin for cell
let margin: CGFloat = 10
In viewDidLoad configure minimumInteritemSpacing
, minimumLineSpacing
, sectionInset
guard let collectionView = docsColl, let flowLayout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout else { return }
flowLayout.minimumInteritemSpacing = margin
flowLayout.minimumLineSpacing = margin
flowLayout.sectionInset = UIEdgeInsets(top: margin, left: margin, bottom: margin, right: margin)
UICollectionViewDataSource method sizeForItemAt
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let noOfCellsInRow = 2 //number of column you want
let flowLayout = collectionViewLayout as! UICollectionViewFlowLayout
let totalSpace = flowLayout.sectionInset.left
+ flowLayout.sectionInset.right
+ (flowLayout.minimumInteritemSpacing * CGFloat(noOfCellsInRow - 1))
let size = Int((collectionView.bounds.width - totalSpace) / CGFloat(noOfCellsInRow))
return CGSize(width: size, height: size)
}
To put space between CollectionItem
s use this
write this two Line in viewdidload
UICollectionViewFlowLayout *collectionViewLayout = (UICollectionViewFlowLayout*)self.collectionView.collectionViewLayout;
collectionViewLayout.sectionInset = UIEdgeInsetsMake(<CGFloat top>, <CGFloat left>, <CGFloat bottom>, <CGFloat right>)
My solution for static sized collection view cells which need to have padding on left and right-
func collectionView(collectionView: UICollectionView,
layout collectionViewLayout: UICollectionViewLayout,
insetForSectionAtIndex section: Int) -> UIEdgeInsets {
let flowLayout = (collectionViewLayout as! UICollectionViewFlowLayout)
let cellSpacing = flowLayout.minimumInteritemSpacing
let cellWidth = flowLayout.itemSize.width
let cellCount = CGFloat(collectionView.numberOfItemsInSection(section))
let collectionViewWidth = collectionView.bounds.size.width
let totalCellWidth = cellCount * cellWidth
let totalCellSpacing = cellSpacing * (cellCount - 1)
let totalCellsWidth = totalCellWidth + totalCellSpacing
let edgeInsets = (collectionViewWidth - totalCellsWidth) / 2.0
return edgeInsets > 0 ? UIEdgeInsetsMake(0, edgeInsets, 0, edgeInsets) : UIEdgeInsetsMake(0, cellSpacing, 0, cellSpacing)
}
As said above you can put it inside a ScrollView
... and if you want the Scroll View to be horizontal put it inside HorizontalScrollView
... and if you want your component (or layout) to support both put inside both of them like this:
<HorizontalScrollView>
<ScrollView>
<!-- SOME THING -->
</ScrollView>
</HorizontalScrollView>
and with setting the layout_width
and layout_height
ofcourse.
A callback is a function that will be called when a process is done executing a specific task.
The usage of a callback is usually in asynchronous logic.
To create a callback in C#, you need to store a function address inside a variable. This is achieved using a delegate
or the new lambda semantic Func
or Action
.
public delegate void WorkCompletedCallBack(string result);
public void DoWork(WorkCompletedCallBack callback)
{
callback("Hello world");
}
public void Test()
{
WorkCompletedCallBack callback = TestCallBack; // Notice that I am referencing a method without its parameter
DoWork(callback);
}
public void TestCallBack(string result)
{
Console.WriteLine(result);
}
In today C#, this could be done using lambda like:
public void DoWork(Action<string> callback)
{
callback("Hello world");
}
public void Test()
{
DoWork((result) => Console.WriteLine(result));
}
You don't need to use JsonConverterAttribute
, keep your model clean, also use CustomCreationConverter
, the code is simpler:
public class SampleConverter : CustomCreationConverter<ISample>
{
public override ISample Create(Type objectType)
{
return new Sample();
}
}
Then:
var sz = JsonConvert.SerializeObject( sampleGroupInstance );
JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter());
Documentation: Deserialize with CustomCreationConverter
The method below is exactly reproducible, so there's no need to run clone again if both sides were consistent, just run the script on the other side too.
git log -n1 --format=%H >.git/info/grafts
git filter-branch -f
rm .git/info/grafts
If you then want to clean it up, try this script:
http://sam.nipl.net/b/git-gc-all-ferocious
I wrote a script which "kills history" for each branch in the repository:
http://sam.nipl.net/b/git-kill-history
see also: http://sam.nipl.net/b/confirm
There's also the approach some shops take of using some of C++'s features in a C-like way, but avoiding ones that are objectionable. For example, using classes and class methods and function overloading (which are usually easy for even C diehards to cope with), but not the STL, stream operators, and Boost (which are harder to learn and can have bad memory characteristics).
It is going to be prettier if you format the seconds output like:
echo "Process took ". number_format(microtime(true) - $start, 2). " seconds.";
will print
Process took 6.45 seconds.
This is much better than
Process took 6.4518549156189 seconds.
class Test extends Thread
{
public void run(){
try{
Thread.sleep(10000);
}catch(InterruptedException e){
System.out.println("test1");
throw new RuntimeException("Thread interrupted..."+e);
}
}
public static void main(String args[]){
Test t1=new Test1();
t1.start();
try{
t1.interrupt();
}catch(Exception e){
System.out.println("test2");
System.out.println("Exception handled "+e);
}
}
}
Its output doesn't contain test2 , so its not handling runtime exception. @jon skeet, @Jan Zyka
You can first verify in the frontend side that the checkbox is marked:
var recaptchaRes = grecaptcha.getResponse();
var message = "";
if(recaptchaRes.length == 0) {
// You can return the message to user
message = "Please complete the reCAPTCHA challenge!";
return false;
} else {
// Add reCAPTCHA response to the POST
form.recaptchaRes = recaptchaRes;
}
And then in the server side verify the received response using Google reCAPTCHA API:
$receivedRecaptcha = $_POST['recaptchaRes'];
$verifiedRecaptcha = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$google_secret.'&response='.$receivedRecaptcha);
$verResponseData = json_decode($verifiedRecaptcha);
if(!$verResponseData->success)
{
return "reCAPTCHA is not valid; Please try again!";
}

I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({name: 'filter'})
export class Filter implements PipeTransform {
transform(array: Array<Object>, filter: Object): any {
let notAllKeysUndefined = false;
let newArray = [];
if(array.length > 0) {
for (let k in filter){
if (filter.hasOwnProperty(k)) {
if(filter[k] != undefined && filter[k] != '') {
for (let i = 0; i < array.length; i++) {
let filterRule = filter[k];
if(typeof filterRule === 'object') {
for(let fkey in filterRule) {
if (filter[k].hasOwnProperty(fkey)) {
if(filter[k][fkey] != undefined && filter[k][fkey] != '') {
if(this.shouldPushInArray(array[i][k][fkey], filter[k][fkey])) {
newArray.push(array[i]);
}
notAllKeysUndefined = true;
}
}
}
} else {
if(this.shouldPushInArray(array[i][k], filter[k])) {
newArray.push(array[i]);
}
notAllKeysUndefined = true;
}
}
}
}
}
if(notAllKeysUndefined) {
return newArray;
}
}
return array;
}
private shouldPushInArray(item, filter) {
if(typeof filter !== 'string') {
item = item.toString();
filter = filter.toString();
}
// Filter main logic
item = item.toLowerCase();
filter = filter.toLowerCase();
if(item.indexOf(filter) !== -1) {
return true;
}
return false;
}
}
I believe what you are looking for is assign_attributes
.
It's basically the same as update_attributes but it doesn't save the record:
class User < ActiveRecord::Base
attr_accessible :name
attr_accessible :name, :is_admin, :as => :admin
end
user = User.new
user.assign_attributes({ :name => 'Josh', :is_admin => true }) # Raises an ActiveModel::MassAssignmentSecurity::Error
user.assign_attributes({ :name => 'Bob'})
user.name # => "Bob"
user.is_admin? # => false
user.new_record? # => true
Actually, the trick is that the command prompt actually understands these non-english characters, just can't display them correctly.
When I enter a path in the command prompt that contains some non-english chracters it is displayed as "?? ?????? ?????". When you submit your command (cd "??? ?????? ?????" in my case), everything is working as expected.
"Dangerous" and "Security risk" are not the first things that spring to mind when people mention iframes … but they can be used in clickjacking attacks.
For those of you that prefer a more concise, easier to read lambda coding style...
This example removes all non-alphanumeric and white space characters from a wide string. You can mix it up with any of the other ctype.h helper functions to remove complex-looking character-based tests.
(I'm not sure how these functions would handle CJK languages, so walk softly there.)
// Boring C loops: 'for(int i=0;i<str.size();i++)'
// Boring C++ eqivalent: 'for(iterator iter=c.begin; iter != c.end; ++iter)'
See if you don't find this easier to understand than noisy C/C++ for/iterator loops:
TSTRING label = _T("1. Replen & Move RPMV");
TSTRING newLabel = label;
set<TCHAR> badChars; // Use ispunct, isalpha, isdigit, et.al. (lambda version, with capture list parameter(s) example; handiest thing since sliced bread)
for_each(label.begin(), label.end(), [&badChars](TCHAR n){
if (!isalpha(n) && !isdigit(n))
badChars.insert(n);
});
for_each(badChars.begin(), badChars.end(), [&newLabel](TCHAR n){
newLabel.erase(std::remove(newLabel.begin(), newLabel.end(), n), newLabel.end());
});
newLabel results after running this code: "1ReplenMoveRPMV"
This is just academic, since it would clearly be more precise, concise and efficient to combine the 'if' logic from lambda0 (first for_each) into the single lambda1 (second for_each), if you have already established which characters are the "badChars".
When the following is invoked within a shell script, the terminal prompt will appear just like many other unix commands do when they are run with sudo
:
# get superuser password
user=$(whoami)
stty -echo
read -p "[sudo] password for $user: " password
stty echo
echo ""
Then you can use $password
as needed.
You can also do the following;
string json = myJObject.ToString(Newtonsoft.Json.Formatting.None);
What is row?
Either of these could be correct.
1) I assume that you capture your ajax response in a javascript variable 'row'. If that is the case, this would hold true.
var result=row.split('|');
alert(result[2]);
otherwise
2) Use this where $(row)
is a jQuery
object.
var result=$(row).val().split('|');
alert(result[2]);
[As mentioned in the other answer, you may have to use $(row).val()
or $(row).text()
or $(row).html()
etc. depending on what $(row) is.]

Hey I thought I would enter my answer to this even though its late. I think there are some important things to consider first with how strong you wish to have the linking between java and python.
Firstly Do you only want to call functions or do you actually want python code to change the data in your java objects? This is very important. If you only want to call some python code with or without arguments, then that is not very difficult. If your arguments are primitives it makes it even more easy. However if you want to have java class implement member functions in python, which change the data of the java object, then this is not so easy or straight forward.
Secondly are we talking cpython or will jython do? I would say cpython is where its at! I would advocate this is why python is so kool! Having such high abstractions however access to c,c++ when needed. Imagine if you could have that in java. This question is not even worth asking if jython is ok because then it is easy anyway.
So I have played with the following methods, and listed them from easy to difficult:
Java to Jython
Advantages: Trivially easy. Have actual references to java objects
Disadvantages: No CPython, Extremely Slow!
Jython from java is so easy, and if this is really enough then great. However it is very slow and no cpython! Is life worth living without cpython I don't think so! You can easily have python code implementing your member functions for you java objects.
Java to Jython to CPython via Pyro
Pyro is the remote object module for python. You have some object on a cpython interpreter, and you can send it objects which are transferred via serialization and it can also return objects via this method. Note that if you send a serialized python object from jython and then call some functions which change the data in its members, then you will not see those changes in java. You just need to remember to send back the data which you want from pyro. This I believe is the easiest way to get to cpython! You do not need any jni or jna or swig or .... You don't need to know any c, or c++. kool huh?
Advantages: Access to cpython, not as difficult as following methods
Disadvantages: Cannot change the member data of java objects directly from python. Is somewhat indirect, (jython is middle man).
Java to C/C++ via JNI/JNA/SWIG to Python via Embedded interpreter (maybe using BOOST Libraries?)
OMG this method is not for the faint of heart. And I can tell you it has taken me very long to achieve this in with a decent method. Main reason you would want to do this is so that you can run cpython code which as full rein over you java object. There are major major things to consider before deciding to try and bread java (which is like a chimp) with python (which is like a horse). Firstly if you crash the interpreter that's lights out for you program! And don't get me started on concurrency issues! In addition, there is allot allot of boiler, I believe I have found the best configuration to minimize this boiler but still it is allot! So how to go about this: Consider that C++ is your middle man, your objects are actually c++ objects! Good that you know that now. Just write your object as if your program as in cpp not java, with the data you want to access from both worlds. Then you can use the wrapper generator called swig (http://www.swig.org/Doc1.3/Java.html) to make this accessible to java and compile a dll which you call System.load(dll name here) in java. Get this working first, then move on to the hard part! To get to python you need to embed an interpreter. Firstly I suggest doing some hello interpreter programs or this tutorial Embedding python in C/C. Once you have that working, its time to make the horse and the monkey dance! You can send you c++ object to python via [boost][3] . I know I have not given you the fish, merely told you where to find the fish. Some pointers to note for this when compiling.
When you compile boost you will need to compile a shared library. And you need to include and link to the stuff you need from jdk, ie jawt.lib, jvm.lib, (you will also need the client jvm.dll in your path when launching the application) As well as the python27.lib or whatever and the boost_python-vc100-mt-1_55.lib. Then include Python/include, jdk/include, boost and only use shared libraries (dlls) otherwise boost has a teary. And yeah full on I know. There are so many ways in which this can go sour. So make sure you get each thing done block by block. Then put them together.
This is another synchronous module that is based off of request and uses promises. Super simple to use, works well with mocha tests.
npm install super-request
request("http://domain.com")
.post("/login")
.form({username: "username", password: "password"})
.expect(200)
.expect({loggedIn: true})
.end() //this request is done
//now start a new one in the same session
.get("/some/protected/route")
.expect(200, {hello: "world"})
.end(function(err){
if(err){
throw err;
}
});
I also had same issue. I investigated and found missing {action} attribute from route template.
Before code (Having Issue):
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
After Fix(Working code):
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
You've got one truly marvelous answer from ray023, but your comment that it's probably overkill is apt. For a "lighter" version....
Block 1 is, IMHO, bad practice. As already pointed out by osknows, mixing error-handling with normal-path code is Not Good. For one thing, if a new error is thrown while there's an Error condition in effect you will not get an opportunity to handle it (unless you're calling from a routine that also has an error handler, where the execution will "bubble up").
Block 2 looks like an imitation of a Try/Catch block. It should be okay, but it's not The VBA Way. Block 3 is a variation on Block 2.
Block 4 is a bare-bones version of The VBA Way. I would strongly advise using it, or something like it, because it's what any other VBA programmer inherting the code will expect. Let me present a small expansion, though:
Private Sub DoSomething()
On Error GoTo ErrHandler
'Dim as required
'functional code that might throw errors
ExitSub:
'any always-execute (cleanup?) code goes here -- analagous to a Finally block.
'don't forget to do this -- you don't want to fall into error handling when there's no error
Exit Sub
ErrHandler:
'can Select Case on Err.Number if there are any you want to handle specially
'display to user
MsgBox "Something's wrong: " & vbCrLf & Err.Description
'or use a central DisplayErr routine, written Public in a Module
DisplayErr Err.Number, Err.Description
Resume ExitSub
Resume
End Sub
Note that second Resume
. This is a trick I learned recently: It will never execute in normal processing, since the Resume <label>
statement will send the execution elsewhere. It can be a godsend for debugging, though. When you get an error notification, choose Debug (or press Ctl-Break, then choose Debug when you get the "Execution was interrupted" message). The next (highlighted) statement will be either the MsgBox
or the following statement. Use "Set Next Statement" (Ctl-F9) to highlight the bare Resume
, then press F8. This will show you exactly where the error was thrown.
As to your objection to this format "jumping around", A) it's what VBA programmers expect, as stated previously, & B) your routines should be short enough that it's not far to jump.
Introducer for the return type of a local lambda expression:
std::vector<MyType> seq;
// fill with instances...
std::sort(seq.begin(), seq.end(),
[] (const MyType& a, const MyType& b) -> bool {
return a.Content < b.Content;
});
introducing a trailing return type of a function in combination of the re-invented auto
:
struct MyType {
// declares a member function returning std::string
auto foo(int) -> std::string;
};
Here's a nice easy way I found:
h <- hist(g, breaks = 10, density = 10,
col = "lightgray", xlab = "Accuracy", main = "Overall")
xfit <- seq(min(g), max(g), length = 40)
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g))
yfit <- yfit * diff(h$mids[1:2]) * length(g)
lines(xfit, yfit, col = "black", lwd = 2)
Sometimes a website doesn't work on my PC and I want to know if it's the website or a problem local to me(e.g. my ISP, my router, etc).
The simplest way to check a website and avoid using your local network resources(and thus avoid any problems caused by them) is using a web proxy such as Proxy.org.
You can also put the tooltip onto one line by removing the "title":
this.chart = new Chart(ctx, {
type: this.props.horizontal ? 'horizontalBar' : 'bar',
options: {
legend: {
display: false,
},
tooltips: {
callbacks: {
label: tooltipItem => `${tooltipItem.yLabel}: ${tooltipItem.xLabel}`,
title: () => null,
}
},
},
});
if the absolute element has a width,you can use the code below
.divtagABS{
width:300px;
positon:absolute;
left:0;
right:0;
margin:0 auto;
}
You can also create border with the color of your wish..
view.layer.borderColor = [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1.0].CGColor;
*r,g,b are the values between 0 to 255.
I was facing the same problem, following code worked for me:
$params = (array) json_decode(file_get_contents('php://input'), TRUE);
print_r($params);

Your select
doesn't have an ID, only a name. You'll need to modify your selector:
$("#pizza").on("click", function(){
$("select[name='pizza_kind']").prop("disabled", !this.checked);
});
Sorry I am a beginner so my coding habit sucks!
public class TitleCase {

str1[k]=sent.charAt(k)+"";
}
for(int i=0;i<=sent.length()-1;i++){

String s= sent.charAt(i)+"";
str1[i]=s.toUpperCase();
}
if(str1[i].equals(" ")){

I recommend use boolean;
. You have to install the boolean module from cpan though.
I am operating in cross-domain scenario. During login remote server is returning Set-Cookie header along with Access-Control-Allow-Credentials
set to true.
The next ajax call to remote server should use this cookie.
CORS's Access-Control-Allow-Credentials
is there to allow cross-domain logging. Check https://developer.mozilla.org/En/HTTP_access_control for examples.
For me it seems like a bug in JQuery (or at least feature-to-be in next version).
UPDATE:
Cookies are not set automatically from AJAX response (citation: http://aleembawany.com/2006/11/14/anatomy-of-a-well-designed-ajax-login-experience/)
Why?
You cannot get value of the cookie from response to set it manually (http://www.w3.org/TR/XMLHttpRequest/#dom-xmlhttprequest-getresponseheader)
I'm confused..
There should exist a way to ask jquery.ajax()
to set XMLHttpRequest.withCredentials = "true"
parameter.
ANSWER:
You should use xhrFields
param of http://api.jquery.com/jQuery.ajax/
The example in the documentation is:
$.ajax({
url: a_cross_domain_url,
xhrFields: {
withCredentials: true
}
});
It's important as well that server answers correctly to this request. Copying here great comments from @Frédéric and @Pebbl:
Important note: when responding to a credentialed request, server must specify a domain, and cannot use wild carding. The above example would fail if the header was wildcarded as: Access-Control-Allow-Origin: *
So when the request is:
Origin: http://foo.example
Cookie: pageAccess=2
Server should respond with:
Access-Control-Allow-Origin: http://foo.example
Access-Control-Allow-Credentials: true
[payload]
Otherwise payload won't be returned to script. See: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials
Just create a new field to bypass this security thing:
var $oldPassword = $("#password");
var $newPassword = $("<input type='text' />")
.val($oldPassword.val())
.appendTo($oldPassword.parent());
$oldPassword.remove();
$newPassword.attr('id','password');
You have to realize that char[10]
is similar to a char*
(see comment by @DarkDust). You are in fact returning a pointer. Now the pointer points to a variable (str
) which is destroyed as soon as you exit the function, so the pointer points to... nothing!
Usually in C, you explicitly allocate memory in this case, which won't be destroyed when the function ends:
char* testfunc()
{
char* str = malloc(10 * sizeof(char));
return str;
}
Be aware though! The memory pointed at by str
is now never destroyed. If you don't take care of this, you get something that is known as a 'memory leak'. Be sure to free()
the memory after you are done with it:
foo = testfunc();
// Do something with your foo
free(foo);
You do this via attributes on the properties, like this:
[Description("Test text displayed in the textbox"),Category("Data")]
public string Text {
get => myInnerTextBox.Text;
set => myInnerTextBox.Text = value;
}
The category is the heading under which the property will appear in the Visual Studio Properties box. Here's a more complete MSDN reference, including a list of categories.
This is what I used to kill the progress on port 4200
For linux users:
sudo kill $(sudo lsof -t -i:4200)
You could also try this:
sudo kill `sudo lsof -t -i:4200`
For windows users:
Port number 4200 is already in use. Open the cmd as administrator. Type below command in cmd:
netstat -a -n -o
And then, find port with port number 4200 by right click on terminal and click find, enter 4200 in "find what" and click "find next": Let say you found that port number 4200 is used by pid 18932. Type below command in cmd:
taskkill -f /pid 18932
For UNIX:
alias ngf='kill -9 $(lsof -t -i:4200);ng serve'
Now run ngf (instead of ng serve) in terminal from the project folder. This will kill all processes using the port 4200 and runs your Angular project.
To ignore untracked files just go to .git/info/exclude. Exclude is a file with a list of ignored extensions or files.
All answers above - do not work. So I will put here a function that works on 4 and 9 android
private String getCurrentLanguage(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
return LocaleList.getDefault().get(0).getLanguage();
} else{
return Locale.getDefault().getLanguage();
}
}
Other answers already explained the difference between user and kernel mode. If you really want to get into detail you should get a copy of Windows Internals, an excellent book written by Mark Russinovich and David Solomon describing the architecture and inside details of the various Windows operating systems.
foo = "blahblahblah"
bar = "somethingblahblahblahmeep"
if foo in bar:
# do something
(By the way - try to not name a variable string
, since there's a Python standard library with the same name. You might confuse people if you do that in a large project, so avoiding collisions like that is a good habit to get into.)
As @PavelAnossov answered, the canonical answer, use the word_tokenize
function in nltk:
from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)
If your sentence is truly simple enough:
Using the string.punctuation
set, remove punctuation then split using the whitespace delimiter:
import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

You don't need both hibernate.cfg.xml
and persistence.xml
in this case. Have you tried removing hibernate.cfg.xml
and mapping everything in persistence.xml
only?
But as the other answer also pointed out, this is not okay like this:
@Id
@JoinColumn(name = "categoria")
private String id;
Didn't you want to use @Column
instead?
You need to include the library path (-L/usr/local/lib/)
gcc -o Opentest Opentest.c -L/usr/local/lib/ -lssl -lcrypto
It works for me.

My project luddite
has this feature.
Example usage:
>>> import luddite
>>> luddite.get_versions_pypi("python-dateutil")
('0.1', '0.3', '0.4', '0.5', '1.0', '1.1', '1.2', '1.4', '1.4.1', '1.5', '2.0', '2.1', '2.2', '2.3', '2.4.0', '2.4.1', '2.4.2', '2.5.0', '2.5.1', '2.5.2', '2.5.3', '2.6.0', '2.6.1', '2.7.0', '2.7.1', '2.7.2', '2.7.3', '2.7.4', '2.7.5', '2.8.0')
It lists all versions of a package available, by querying the json API of https://pypi.org/

name2 = value_2
bash script with read and execute
/bin/parseini
#!/bin/bash

sVa=${BASH_REMATCH[2]}
set -a
eval "$(echo "$sNm"=\""$sVa"\")"
set +a

done < $1
then in another script I source the results of the command and can use any variables within

I just ran across this in my RSS Reader today. I've got a cleaner solution for you. This example is in Delphi, but can very easily be converted to C/C++ (It's all Win32).
Query all value names from the following registry location: HKLM\SYSTEM\MountedDevices
One by one, pass them into the following function and you will be returned the device name. Pretty clean and simple! I found this code on a blog here.
function VolumeNameToDeviceName(const VolName: String): String;
var
s: String;
TargetPath: Array[0..MAX_PATH] of WideChar;
bSucceeded: Boolean;
begin
Result := ”;
// VolumeName has a format like this: \\?\Volume{c4ee0265-bada-11dd-9cd5-806e6f6e6963}\
// We need to strip this to Volume{c4ee0265-bada-11dd-9cd5-806e6f6e6963}
s := Copy(VolName, 5, Length(VolName) - 5);
bSucceeded := QueryDosDeviceW(PWideChar(WideString(s)), TargetPath, MAX_PATH) <> 0;
if bSucceeded then
begin
Result := TargetPath;
end
else begin
// raise exception
end;
end;
String s;
Format formatter;
Date date = new Date();
// 2012-12-01
formatter = new SimpleDateFormat("yyyy-MM-dd");
s = formatter.format(date);
System.out.println(s);
If you want to change your library path permanently (without calling .libPath() every time when entering in R, this works for me:
create .Rprofile under your home directory. (~/.Rprofile)
type
.libPaths(c( .libPaths(), "your new path" ))
in .Rprofile file, save.
open R (any directory) and check, just type .libPaths()
, you can find your libaray path is updated!
According to my understanding, Application.Current.Shutdown()
also has its drawback.
If you want to show a confirmation window to let users confirm on quit or not, Application.Current.Shutdown()
is irreversible.
My super lazy version of showing a copyright line, that automatically stays updated:
© <?php
$copyYear = 2008;
$curYear = date('Y');
echo $copyYear . (($copyYear != $curYear) ? '-' . $curYear : '');
?> Me, Inc.
This year (2008), it will say:
© 2008 Me, Inc.
Next year, it will say:
© 2008-2009 Me, Inc.
and forever stay updated with the current year.
Or (PHP 5.3.0+) a compact way to do it using an anonymous function so you don't have variables leaking out and don't repeat code/constants:
©
<?php call_user_func(function($y){$c=date('Y');echo $y.(($y!=$c)?'-'.$c:'');}, 2008); ?>
Me, Inc.
Microsoft converts your Int16
variables into Int32
when doing the add function.
Change the following:
Int16 answer = firstNo + secondNo;
into...
Int16 answer = (Int16)(firstNo + secondNo);
Like others have already noted, you can use :empty
in jQuery like this:
$('#cartContent:empty').remove();
It will remove the #cartContent
div if it is empty.
But this and other techniques that people are suggesting here may not do what you want because if it has any text nodes containing whitespace it is not considered empty. So this is not empty:
<div> </div>
while you may want to consider it empty.
I had this problem some time ago and I wrote this tiny jQuery plugin - just add it to your code:
jQuery.expr[':'].space = function(elem) {
var $elem = jQuery(elem);
return !$elem.children().length && !$elem.text().match(/\S/);
}
and now you can use
$('#cartContent:space').remove();
which will remove the div if it is empty or contains only whitespace. Of course you can not only remove it but do anything you like, like
$('#cartContent:space').append('<p>It is empty</p>');
and you can use :not
like this:
$('#cartContent:not(:space)').append('<p>It is not empty</p>');
I came out with this test that reliably did what I wanted and you can take it out of the plugin to use it as a standalone test:
This one will work for jQuery objects:
function testEmpty($elem) {
return !$elem.children().length && !$elem.text().match(/\S/);
}
This one will work for DOM nodes:
function testEmpty(elem) {
var $elem = jQuery(elem);
return !$elem.children().length && !$elem.text().match(/\S/);
}
This is better than using .trim
because the above code first tests if the tested element has any child elements and if it does it tries to find the first non-whitespace character and then stops, without the need to read or mutate the string if it has even one character that is not whitespace.
Hope it helps.
If you are using OneDrive, or any similar network drive, you have 2 options:
1) the easy one is to move the folder to a local directory inside your PC (eg:. C:).
2) but if you want to keep using OneDrive I would recommend to add it to the trusted sites on the internet explorer options and that will fix the problem.
You want:
if (document.getElementById('customx').value === ""){
//do something
}
The value
property will give you a string value and you need to compare that against an empty string.
To identifiy iPhone 4S, simply check the following:
var isIphone4S: Bool {
let width = UIScreen.main.bounds.size.width
let height = UIScreen.main.bounds.size.height
let proportions = width > height ? width / height : height / width
return proportions == 1.5 && UIDevice.current.model == "iPhone"
}
Use a subquery:
SELECT * FROM (
SELECT * FROM users ORDER BY RAND() LIMIT 20
) u
ORDER BY name
or a join to itself:
SELECT * FROM users u1
INNER JOIN (
SELECT id FROM users ORDER BY RAND() LIMIT 20
) u2 USING(id)
ORDER BY u1.name
First you need to export HTTP_PROXY
. Second, you need to read man sudo
carefully, and pay attention to the -E
flag. This works:
$ export HTTP_PROXY=foof
$ sudo -E bash -c 'echo $HTTP_PROXY'
Here is the quote from the man page:
-E, --preserve-env
Indicates to the security policy that the user wishes to preserve their
existing environment variables. The security policy may return an error
if the user does not have permission to preserve the environment.
The most fundamental thing here probably is that you don't want to transmit static images but only changes to the images, which essentially is analogous to video stream.
My best guess is some very efficient (and heavily specialized and optimized) motion compensation algorithm, because most of the actual change in generic desktop usage is linear movement of elements (scrolling text, moving windows, etc. opposed to transformation of elements).
The DirectX 3D performance of 1 FPS seems to confirm my guess to some extent.

From the source code:
// Instance of WebViewClient that is the client callback.
private volatile WebViewClient mWebViewClient;
// Instance of WebChromeClient for handling all chrome functions.
private volatile WebChromeClient mWebChromeClient;
// SOME OTHER SUTFFF.......
/**
* Set the WebViewClient.
* @param client An implementation of WebViewClient.
*/
public void setWebViewClient(WebViewClient client) {
mWebViewClient = client;
}
/**
* Set the WebChromeClient.
* @param client An implementation of WebChromeClient.
*/
public void setWebChromeClient(WebChromeClient client) {
mWebChromeClient = client;
}
Using WebChromeClient allows you to handle Javascript dialogs, favicons, titles, and the progress. Take a look of this example: Adding alert() support to a WebView
At first glance, there are too many differences WebViewClient & WebChromeClient. But, basically: if you are developing a WebView that won't require too many features but rendering HTML, you can just use a WebViewClient
. On the other hand, if you want to (for instance) load the favicon of the page you are rendering, you should use a WebChromeClient
object and override the onReceivedIcon(WebView view, Bitmap icon)
.
Most of the times, if you don't want to worry about those things... you can just do this:
webView= (WebView) findViewById(R.id.webview);
webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
And your WebView will (in theory) have all features implemented (as the android native browser).
The above solutions missed out on where to keep your backup (.bak) file. This should do the trick. It worked for me.
We solved this issue here at work by applying a .dropup class to the dropdown when the dropdown is close to the bottom of a table.enter image description here
For Node/Express developers you can use middleware and set this via server.
app.use(function(req, res, next) {
res.setHeader('X-UA-Compatible', 'IE=edge');
next();
});
function getPercentUsed() {
$sys = system("df -h /dev/sda6 --output=pcent | grep -o '[0-9]*'", $val);
return $val[0];
}
The way you are doing it is indeed the recommended one (for Python 2.x).
The issue of whether the class is passed explicitly to super
is a matter of style rather than functionality. Passing the class to super
fits in with Python's philosophy of "explicit is better than implicit".
$deleted = $_POST['checkbox'];
$sql = "DELETE FROM $tbl_name WHERE id IN (".implode(",", $deleted ) . ")";
I was checking for solutions to encoding since ages, and this page is probably the conclusion of years of search! I tested some of the suggestions you mentioned and here's my notes:
This is my test string:
this is a "wròng wrìtten" string bùt I nèed to pù 'sòme' special chàrs to see thèm, convertèd by fùnctìon!! & that's it!
I do an INSERT to save this string on a database in a field that is set as utf8_general_ci
The character set of my page is UTF-8.
If I do an INSERT just like that, in my database, I have some characters probably coming from Mars...
So I need to convert them into some "sane" UTF-8. I tried utf8_encode()
, but still aliens chars were invading my database...
So I tried to use the function forceUTF8
posted on number 8, but in the database the string saved looks like this:
this is a "wròng wrìtten" string bùt I nèed to pù 'sòme' special chà rs to see thèm, convertèd by fùnctìon!! & that's it!
So collecting some more information on this page and merging them with other information on other pages I solved my problem with this solution:
$finallyIDidIt = mb_convert_encoding(
$string,
mysql_client_encoding($resourceID),
mb_detect_encoding($string)
);
Now in my database I have my string with correct encoding.
NOTE:
Only note to take care of is in function mysql_client_encoding
!
You need to be connected to the database, because this function wants a resource ID as a parameter.
But well, I just do that re-encoding before my INSERT so for me it is not a problem.
There's no easy way (in terms of performance) to do what you want to do.
Reflection works with assemblys and types mainly so you'll have to get all the types of the assembly and query them for the right interface. Here's an example:
Assembly asm = Assembly.Load("MyAssembly");
Type[] types = asm.GetTypes();
Type[] result = types.where(x => x.GetInterface("IMyInterface") != null);
That will get you all the types that implement the IMyInterface in the Assembly MyAssembly
You didn't specify which flavor of regex you're using, but this will work in any of the most popular ones that can be considered "complete".
/.+?(?=abc)/
The .+?
part is the un-greedy version of .+
(one or more of
anything). When we use .+
, the engine will basically match everything.
Then, if there is something else in the regex it will go back in steps
trying to match the following part. This is the greedy behavior,
meaning as much as possible to satisfy.
When using .+?
, instead of matching all at once and going back for
other conditions (if any), the engine will match the next characters by
step until the subsequent part of the regex is matched (again if any).
This is the un-greedy, meaning match the fewest possible to
satisfy.
/.+X/ ~ "abcXabcXabcX" /.+/ ~ "abcXabcXabcX"
^^^^^^^^^^^^ ^^^^^^^^^^^^
/.+?X/ ~ "abcXabcXabcX" /.+?/ ~ "abcXabcXabcX"
^^^^ ^
Following that we have (?=
{contents}
)
, a zero width
assertion, a look around. This grouped construction matches its
contents, but does not count as characters matched (zero width). It
only returns if it is a match or not (assertion).
Thus, in other terms the regex /.+?(?=abc)/
means:
Match any characters as few as possible until a "abc" is found, without counting the "abc".
Pure/vanilla JS solution (working example here)
// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']");
// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])");
In querySelectorAll you must use valid CSS selector (currently Level3)
SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):
PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).
So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)

You must reference it. To do this, open the shortcut menu for the project in Solution Explorer, and then choose References. In the Property Pages dialog box, expand the Common Properties node, select Framework and References, and then choose the Add New Reference button.
In a more basic way to explain: An interface is sort of like an empty muffin pan. It's a class file with a set of method definitions that have no code.
An abstract class is the same thing, but not all functions need to be empty. Some can have code. It's not strictly empty.
Why differentiate: There's not much practical difference in Python, but on the planning level for a large project, it could be more common to talk about interfaces, since there's no code. Especially if you're working with Java programmers who are accustomed to the term.
First, the network name is likely "Ethernet", not "Local Area Connection". To find out the name you can do this:
netsh interface show interface
Which will show the name under the "Interface Name" column (shown here in bold):
Admin State State Type Interface Name ------------------------------------------------------------------------- Enabled Connected Dedicated Ethernet
Now you can change the primary dns (index=1), assuming that your interface is static (not using dhcp):
netsh interface ipv4 add dnsserver "Ethernet" address=192.168.x.x index=1
2018 Update - The command will work with either dnsserver
(singular) or dnsservers
(plural). The following example uses the latter and is valid as well:
netsh interface ipv4 add dnsservers "Ethernet" address=192.168.x.x index=1
Note: Posted this answer because OP later stated in comments that they need to select the last two elements, not just the second to last one.
The :nth-child
CSS3 selector is in fact more capable than you ever imagined!
For example, this will select the last 2 elements of #container
:
#container :nth-last-child(-n+2) {}
But this is just the beginning of a beautiful friendship.
#container :nth-last-child(-n+2) {
background-color: cyan;
}

I was able to achieve this in ASP.NET MVC using the client IP address and freegeoip.net API. freegeoip.net is free and does not require any license.
Below is the sample code I used.
String UserIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (string.IsNullOrEmpty(UserIP))
{
UserIP = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}
string url = "http://freegeoip.net/json/" + UserIP.ToString();
WebClient client = new WebClient();
string jsonstring = client.DownloadString(url);
dynamic dynObj = JsonConvert.DeserializeObject(jsonstring);
System.Web.HttpContext.Current.Session["UserCountryCode"] = dynObj.country_code;

I would think you should add it to ~/.bash_profile
instead of .bashrc
, (creating .bash_profile
if it doesn't exist.) Then you don't have to add the extra step of checking for ~/.bashrc
in your .bash_profile
Are you comfortable working and editing in a terminal? Just in case, ~/
means your home directory, so if you open a new terminal window that is where you will be "located". And the dot at the front makes the file invisible to normal ls
command, unless you put -a
or specify the file name.
Check this answer for more detail.
Enums are the recommended way to provide easy-to-remember names for a defined set of contants (optionally with some limited behaviour too).
You should use enums where otherwise you would use multiple static integer constants (eg. public static int ROLE_ADMIN = 0
or BLOOD_TYPE_AB = 2
)
The main advantages of using enums instead of these are type safety, compile type warnings/errors when trying to use wrong values and providing a namespace for related "constants". Additionally they are easier to use within an IDE since it helps code completion too.
Not this exact problem, but this is the top result when googling for almost the exact same error:
If you see this problem calling a WCF Service hosted on the same machine, you may need to populate the BackConnectionHostNames
registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
MSV1_0
, point to New, and then click Multi-String Value
.BackConnectionHostNames
, and then press ENTER.BackConnectionHostNames
, and then click Modify.
In the Value data box, type the CNAME or the DNS alias, that is used for the local shares on the computer, and then click OK.
See Calling WCF service hosted in IIS on the same machine as client throws authentication error for details.
you need to add it like
insert into table1(date1) values('12-mar-2013');
Well, I got it. One way is to override the QWidget::closeEvent
(QCloseEvent *event)
method in your class definition and add your code into that function. Example:
class foo : public QMainWindow
{
Q_OBJECT
private:
void closeEvent(QCloseEvent *bar);
// ...
};
void foo::closeEvent(QCloseEvent *bar)
{
// Do something
bar->accept();
}
Disclaimer: I am involved in the rest2mobile open source project
Another alternative as a REST client is to use rest2mobile.
The approach is slightly different as it uses concrete rest examples to generate the client code for the REST service. The code replaces the REST URL and JSON payloads with native java methods and POJOs. It also automatically handles server connections, asynchronous invocations and POJO to/from JSON conversions.
Note that this tool comes in different flavors (cli, plugins, android/ios/js support) and you can use the android studio plugin to generate the API directly into your app.
All the code can be found on github here.
You are trying to do a logarithm of something that is not positive.
Logarithms figure out the base after being given a number and the power it was raised to. log(0)
means that something raised to the power of 2
is 0
. An exponent can never result in 0
*, which means that log(0)
has no answer, thus throwing the math domain error
*Note: 0^0
can result in 0
, but can also result in 1
at the same time. This problem is heavily argued over.
Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.
So first you need to set up a class with some variables to get/set:
public class IDCard
{
private String mName;
private String mFileName;
private int mID;
}
But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:
IDCard test = new IDCard();
So - let's set up a default constructor, this is the method being called when you "instantiate" a class.
public IDCard()
{
mName = "";
mFileName = "";
mID = -1;
}
But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:
public IDCard(String name, int ID, String filename)
{
mName = name;
mID = ID;
mFileName = filename;
}
Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:
public String getName()
{
return mName;
}
public void setName( String name )
{
mName = name;
}
Nice. Now we can access mName
. Add the rest of the accessors and mutators and you're now a certified Java newbie.
Good luck.
My approach would be to use the clone()
method of jQuery. It creates a copy of your element, and that's what you want : a copy of your first unaltered modal, that you can replace at your wish : Demo (jsfiddle)
var myBackup = $('#myModal').clone();
// Delegated events because we make a copy, and the copied button does not exist onDomReady
$('body').on('click','#myReset',function() {
$('#myModal').modal('hide').remove();
var myClone = myBackup.clone();
$('body').append(myClone);
});
The markup I used is the most basic, so you just need to bind on the right elements / events, and you should have your wizard reset.
Be careful to bind with delegated events, or rebind at each reset the inner elements of your modal so that each new modal behave the same way.
As Niklas mentioned you can use the html2canvas library to take a screenshot using JS in the browser. I will extend his answer in this point by providing an example of taking a screenshot using this library ("Proof of Concept"):
function report() {
let region = document.querySelector("body"); // whole screen
html2canvas(region, {
onrendered: function(canvas) {
let pngUrl = canvas.toDataURL(); // png in dataURL format
let img = document.querySelector(".screen");
img.src = pngUrl;
// here you can allow user to set bug-region
// and send it with 'pngUrl' to server
},
});
}
_x000D_
.container {
margin-top: 10px;
border: solid 1px black;
}
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<div>Screenshot tester</div>
<button onclick="report()">Take screenshot</button>
<div class="container">
<img width="75%" class="screen">
</div>
_x000D_
In report()
function in onrendered
after getting image as data URI you can show it to the user and allow him to draw "bug region" by mouse and then send a screenshot and region coordinates to the server.
In this example async/await
version was made: with nice makeScreenshot()
function.
Simple example which allows you to take screenshot, select region, describe bug and send POST request (here jsfiddle) (the main function is report()
).
async function report() {

The solution, as Yuki already pointed, is to capitalize the component name. It's important to note that not only the "default" App component needs to be capitalized, but all components:
const Person = () => {return ...};
export default Person;
This is due to eslint-plugin-react-hooks package, specifically isComponentName() function inside RulesOfHooks.js script.
Official explanation from Hooks FAQs:
We provide an ESLint plugin that enforces rules of Hooks to avoid bugs. It assumes that any function starting with ”use” and a capital letter right after it is a Hook. We recognize this heuristic isn’t perfect and there may be some false positives, but without an ecosystem-wide convention there is just no way to make Hooks work well — and longer names will discourage people from either adopting Hooks or following the convention.
It's hard to tell without looking at the full code but this type of error
Uncaught TypeError: $(...).slick is not a function
Usually means that you either forgot to include slick.js in the page or you included it before jquery.
Make sure jquery is the first js file and you included the slick.js library after it.
Let’s say you are making an executable that uses some functions found in a library.
If the library you are using is static, the linker will copy the object code for these functions directly from the library and insert them into the executable.
Now if this executable is run it has every thing it needs, so the executable loader just loads it into memory and runs it.
If the library is dynamic the linker will not insert object code but rather it will insert a stub which basically says this function is located in this DLL at this location.
Now if this executable is run, bits of the executable are missing (i.e the stubs) so the loader goes through the executable fixing up the missing stubs. Only after all the stubs have been resolved will the executable be allowed to run.
To see this in action delete or rename the DLL and watch how the loader will report a missing DLL error when you try to run the executable.
Hence the name Dynamic Link Library, parts of the linking process is being done dynamically at run time by the executable loader.
One a final note, if you don't link to the DLL then no stubs will be inserted by the linker, but Windows still provides the GetProcAddress API that allows you to load an execute the DLL function entry point long after the executable has started.
You can very easily override the val
function to trigger change by replacing it with a proxy to the original val
function.
just add This code somewhere in your document (after loading jQuery)
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var result =originalVal.apply(this,arguments);
if(arguments.length>0)
$(this).change(); // OR with custom event $(this).trigger('value-changed');
return result;
};
})(jQuery);
A working example: here
(Note that this will always trigger change
when val(new_val)
is called even if the value didn't actually changed.)
If you want to trigger change ONLY when the value actually changed, use this one:
//This will trigger "change" event when "val(new_val)" called
//with value different than the current one
(function($){
var originalVal = $.fn.val;
$.fn.val = function(){
var prev;
if(arguments.length>0){
prev = originalVal.apply(this,[]);
}
var result =originalVal.apply(this,arguments);
if(arguments.length>0 && prev!=originalVal.apply(this,[]))
$(this).change(); // OR with custom event $(this).trigger('value-changed')
return result;
};
})(jQuery);
Live example for that: http://jsfiddle.net/5fSmx/1/

To append to an object use Object.assign
var ElementList ={}
function addElement (ElementList, element) {
let newList = Object.assign(ElementList, element)
return newList
}
console.log(ElementList)
Output:
{"element":{"id":10,"quantity":1},"element":{"id":11,"quantity":2}}
The best way to reset a sequence to start back with number 1 is to execute the following:
ALTER SEQUENCE <tablename>_<id>_seq RESTART WITH 1
So, for example for the users table it would be:
ALTER SEQUENCE users_id_seq RESTART WITH 1
Not directly. But you can use extensions such as LESS to help you achieve the same.
Double the backslashes in the path, like this:
driver.findElement(browsebutton).sendKeys("C:\\Users\\Desktop\\Training\\Training.jpg");
let arr = [2,5,3,5,6,7,1];
let max = Math.max(...arr); // 7
let min = Math.min(...arr); // 1
It's very simple to import a .bson file:
mongorestore -d db_name -c collection_name /path/file.bson
Incase only for a single collection.Try this:
mongorestore --drop -d db_name -c collection_name /path/file.bson
For restoring the complete folder exported by mongodump
:
mongorestore -d db_name /path/
You tried to paste it using

Sadly whenever you enter CTRL +V on terminal it adds

the character that you only appears after you

So your link becomes ^?https://...
which is invalid.
If the variable is not going to change you could use define
Example:
define('FOOTER_CONTENT', 'Hello I\'m an awesome footer!');
function footer()
{
echo FOOTER_CONTENT;
}
According to my concern, if we want to stable the OUTPUT OF CONSOLE APPLICATION, till the close of output display USE, the label: after the MainMethod, and goto label; before end of the program

{
label:

goto label;
}
You want to use the csv module that is part of the python language and you should use Django's get_or_create method
with open(path) as f:
reader = csv.reader(f)
for row in reader:
_, created = Teacher.objects.get_or_create(
first_name=row[0],
last_name=row[1],
middle_name=row[2],
)
# creates a tuple of the new object or
# current object and a boolean of if it was created
In my example the model teacher has three attributes first_name, last_name and middle_name.
Django documentation of get_or_create method
Depending on the hibernate flush mode that you are using (AUTO
is the default) save
may or may not write your changes to the DB straight away. When you call saveAndFlush
you are enforcing the synchronization of your model state with the DB.
If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save()
and saveAndFlush()
because the select triggers a flush first. See the documention.
PLEASE ADD REASON FOR DOWNVOTE
No need to use any external library to extend
In JavaScript, everything is an object (except for the three primitive datatypes, and even they are automatically wrapped with objects when needed). Furthermore, all objects are mutable.
Class Person in JavaScript
function Person(name, age) {
this.name = name;
this.age = age;
}
Person.prototype = {
getName: function() {
return this.name;
},
getAge: function() {
return this.age;
}
}
/* Instantiate the class. */
var alice = new Person('Alice', 93);
var bill = new Person('Bill', 30);
Modify a specific instance/object.
alice.displayGreeting = function()
{
alert(this.getGreeting());
}
Modify the class
Person.prototype.getGreeting = function()
{
return 'Hi ' + this.getName() + '!';
};
Or simply say : extend JSON and OBJECT both are same
var k = {
name : 'jack',
age : 30
}
k.gender = 'male'; /*object or json k got extended with new property gender*/

for completeness: if you created your own subclass of UITableViewCell
you can implement the - (void)setSelected:(BOOL)selected animated:(BOOL)animated
method, and set the background color of some view you added in the content view. (if that is the case) or of the contentView itself (if it is not covered by one of your own views.
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
if(selected) {
self.contentView.backgroundColor = UIColor.blueColor;
} else {
self.contentView.backgroundColor = UIColor.whiteColor;
}
}
(did not use ? to fit the small width of source code DIV's :)
this approach has two advantages over using selectedBackgroundView, it uses less memory, and slightly less CPU, not that u would even notice unless u display hundreds of cells.
Here's a solution using xml_grep (because xpath wasn't part of our distributable and I didn't want to add it to all production machines)...
If you are looking for a specific setting in an XML file, and if all elements at a given tree level are unique, and there are no attributes, then you can use this handy function:
# File to be parsed
xmlFile="xxxxxxx"
# use xml_grep to find settings in an XML file
# Input ($1): path to setting
function getXmlSetting() {
# Filter out the element name for parsing
local element=`echo $1 | sed 's/^.*\///'`
# Verify the element is not empty
local check=${element:?getXmlSetting invalid input: $1}
# Parse out the CDATA from the XML element
# 1) Find the element (xml_grep)
# 2) Remove newlines (tr -d \n)
# 3) Extract CDATA by looking for *element> CDATA <element*
# 4) Remove leading and trailing spaces
local getXmlSettingResult=`xml_grep --cond $1 $xmlFile 2>/dev/null | tr -d '\n' | sed -n -e "s/.*$element>[[:space:]]*\([^[:space:]].*[^[:space:]]\)[[:space:]]*<\/$element.*/\1/p"`
# Return the result
echo $getXmlSettingResult
}
#EXAMPLE
logPath=`getXmlSetting //config/logs/path`
check=${logPath:?"XML file missing //config/logs/path"}
This will work with this structure:
<config>
<logs>
<path>/path/to/logs</path>
<logs>
</config>
It will also work with this (but it won't keep the newlines):
<config>
<logs>
<path>
/path/to/logs
</path>
<logs>
</config>
If you have duplicate <config> or <logs> or <path>, then it will only return the last one. You can probably modify the function to return an array if it finds multiple matches.
FYI: This code works on RedHat 6.3 with GNU BASH 4.1.2, but I don't think I'm doing anything particular to that, so should work everywhere.
NOTE: For anybody new to scripting, make sure you use the right types of quotes, all three are used in this code (normal single quote '=literal, backward single quote `=execute, and double quote "=group).
I think you can't increase the time for query execution, but you need to increase the timeout for the request.
Execution Timeout Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET. (Default time is 110 seconds.)
For Details, please have a look at https://msdn.microsoft.com/en-us/library/e1f13641%28v=vs.100%29.aspx
You can do in the web.config. e.g
<httpRuntime maxRequestLength="2097152" executionTimeout="600" />
import re
mylist = [x for x in re.compile('\s*[,|\s+]\s*').split(string)]
Simply, comma or at least one white spaces with/without preceding/succeeding white spaces.
Please try!
I have found a variety of runtimes including Visual Studio(VS) versions are available at http://scn.sap.com/docs/DOC-7824
Service references deal with endpoints and bindings, which are completely configurable. They let you point your client proxy to a WCF via any transport protocol (HTTP, TCP, Shared Memory, etc)
They are designed to work with WCF.
If you use a WebProxy, you are pretty much binding yourself to using WCF over HTTP
Have you changed your Windows password recently, or at least the one you use to connect to your proxy?
This was my problem, and git status

The elements of a sequence need to be indented at the same level. Assuming you want two jobs (A and B) each with an ordered list of key value pairs, you should use:
jobs:
- - name: A
- schedule: "0 0/5 * 1/1 * ? *"
- - type: mongodb.cluster
- config:
- host: mongodb://localhost:27017/admin?replicaSet=rs
- minSecondaries: 2
- minOplogHours: 100
- maxSecondaryDelay: 120
- - name: B
- schedule: "0 0/5 * 1/1 * ? *"
- - type: mongodb.cluster
- config:
- host: mongodb://localhost:27017/admin?replicaSet=rs
- minSecondaries: 2
- minOplogHours: 100
- maxSecondaryDelay: 120
Converting the sequences of (single entry) mappings to a mapping as @Tsyvarrev does is also possible, but makes you lose the ordering.
As of 2015, it now just works.
<input type="file">
This will ask user for the upload of any file. On iOS 8.x this can be a camera video, camera photo, or a photo/video from Photo Library.
<input type="file" accept="image/*">
This is as above, but limits the uploads to photos only from camera or library, no videos.
Short answer: You are calling a file/directory as a function instead of real function
Read on:
This kind of error happens when you import module thinking it as function and call it. So in python module is a .py file. Packages(directories) can also be considered as modules. Let's say I have a create.py file. In that file I have a function like this:
#inside create.py
def create():
pass
Now, in another code file if I do like this:
#inside main.py file
import create
create() #here create refers to create.py , so create.create() would work here
It gives this error as am calling the create.py file as a function. so I gotta do this:
from create import create
create() #now it works.
Hope that helps! Happy Coding!
This is a little rough around the edges but a little more novice friendly.
if [ $number -ge 0 ]
then
echo "Continue with code block"
else
echo "We matched 0 or $number is not a number"
fi
This will cause an error and print "Illegal number:" if $number is not a number but it will not break out of the script. Oddly there is not a test option I could find to just test for an integer. The logic here will match any number that is greater than or equal to 0.
For subsections it's as easy as leveraging strings in ng-include:
<ul id="subNav">
<li><a ng-click="subPage='section1/subpage1.htm'">Sub Page 1</a></li>
<li><a ng-click="subPage='section1/subpage2.htm'">Sub Page 2</a></li>
<li><a ng-click="subPage='section1/subpage3.htm'">Sub Page 3</a></li>
</ul>
<ng-include src="subPage"></ng-include>
Or you can create an object in case you have links to sub pages all over the place:
$scope.pages = { page1: 'section1/subpage1.htm', ... };
<ul id="subNav">
<li><a ng-click="subPage='page1'">Sub Page 1</a></li>
<li><a ng-click="subPage='page2'">Sub Page 2</a></li>
<li><a ng-click="subPage='page3'">Sub Page 3</a></li>
</ul>
<ng-include src="pages[subPage]"></ng-include>
Or you can even use $routeParams
$routeProvider.when('/home', ...);
$routeProvider.when('/home/:tab', ...);
$scope.params = $routeParams;
<ul id="subNav">
<li><a href="#/home/tab1">Sub Page 1</a></li>
<li><a href="#/home/tab2">Sub Page 2</a></li>
<li><a href="#/home/tab3">Sub Page 3</a></li>
</ul>
<ng-include src=" '/home/' + tab + '.html' "></ng-include>
You can also put an ng-controller at the top-most level of each partial
Try numpy.clip
:
>>> import numpy
>>> a = numpy.arange(-10, 10)
>>> a
array([-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2,
3, 4, 5, 6, 7, 8, 9])
>>> a.clip(0, 10)
array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
You can clip only the bottom half with clip(0)
.
>>> a = numpy.array([1, 2, 3, -4, 5])
>>> a.clip(0)
array([1, 2, 3, 0, 5])
You can clip only the top half with clip(max=n)
. (This is much better than my previous suggestion, which involved passing NaN
to the first parameter and using out
to coerce the type.):
>>> a.clip(max=2)
array([ 1, 2, 2, -4, 2])
Another interesting approach is to use where
:
>>> numpy.where(a <= 2, a, 2)
array([ 1, 2, 2, -4, 2])
Finally, consider aix's answer. I prefer clip
for simple operations because it's self-documenting, but his answer is preferable for more complex operations.
I know I am replying too late but for anyone else who needs this, run following command from your local machine
cat ~/.ssh/id_rsa.pub | ssh [email protected] "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
this has worked perfectly fine. All you need to do is just to replace
with your own user for that particular host
You don't need to use setAttribute for that - This code works (IE8 also)
<div id="something" >Hello</div>
<script type="text/javascript" >
(function() {
document.getElementById("something").onclick = function() {
alert('hello');
};
})();
</script>
If you wrap the container in a dummy P
tag you will get the container HTML also.
All you need to do is
var x = $('#container').wrap('<p/>').parent().html();
Check working example at http://jsfiddle.net/rzfPP/68/
To unwrap()
the <p>
tag when done, you can add
$('#container').unwrap();
You can use a Handler to post runnable code. This technique is outlined very nicely here: https://guides.codepath.com/android/Repeating-Periodic-Tasks

The system I was working on is Windows Server 2008 Standard with IIS 7 (I guess that my experience will apply for all Windows systems of the same age).
Running
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
SEEMED to work, as
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -lv
showed the .Net framework v4 registered with IIS.
But, running the same for .Net v2, namely
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
did NOT result in
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -lv
showing the framework registered.
(And, for me, the installer for Kofax Capture Network Server was still missing ASP.NET.)
The solution was:
After that, aspnet_regiis.exe -lv (either version) shows the framework registered. (And the Kofax installer was also happy and worked.)
At the risk of restating what has already been said, it seems important to remember that PUT implies that the client controls what the URL is going to end up being, when creating a resource. So part of the choice between PUT and POST is going to be about how much you can trust the client to provide correct, normalized URL that are coherent with whatever your URL scheme is.
When you can't fully trust the client to do the right thing, it would be more appropriate to use POST to create a new item and then send the URL back to the client in the response.
$(function(){
$(window).resize(function(){
var h = $(window).height();
var w = $(window).width();
$("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
});
});
Scrollbars etc have an effect on the window size so you may want to tweak to desired size.

It worked perfectly well for me.

An old thread, sure, but a popular one apparently. It's 2020 now and none of these answers have addressed the issue of unreadable code. @pimvdb's answer takes up less lines, but it's also pretty complicated to follow. For easier debugging and better readability, I should suggest refactoring the OP's code to something like this, and adopting an early return pattern, as this is likely the main reason you were unsure of why the were getting undefined:
function validatePassword() {
const password = document.getElementById("password");
const confirm_password = document.getElementById("password_confirm");
if (password.value.length === 0) {
return false;
}
if (password.value !== confirm_password.value) {
return false;
}
return true;
}
Since nobody mentioned it:
I found request.env['HTTP_X_FORWARDED_FOR']
very useful too in cases when request.remote_ip
returns 127.0.0.1
As you can see in mongo docs - since version 3.2 $text
index is case-insensitive by default: https://docs.mongodb.com/manual/core/index-text/#text-index-case-insensitivity
Instead of setting absolute widths and heights, you can use percentages:
#mydiv img {
height: 100%;
width: 100%;
}
Yes, use the File API, then you can process the images with the canvas element.
This Mozilla Hacks blog post walks you through most of the process. For reference here's the assembled source code from the blog post:
// from an input element
var filesToUpload = input.files;
var file = filesToUpload[0];
var img = document.createElement("img");
var reader = new FileReader();
reader.onload = function(e) {img.src = e.target.result}
reader.readAsDataURL(file);
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0);
var MAX_WIDTH = 800;
var MAX_HEIGHT = 600;
var width = img.width;
var height = img.height;
if (width > height) {
if (width > MAX_WIDTH) {
height *= MAX_WIDTH / width;
width = MAX_WIDTH;
}
} else {
if (height > MAX_HEIGHT) {
width *= MAX_HEIGHT / height;
height = MAX_HEIGHT;
}
}
canvas.width = width;
canvas.height = height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, width, height);
var dataurl = canvas.toDataURL("image/png");
//Post dataurl to the server with AJAX
I did this by using data attributes. Is a lot cleaner than other methods attempting to explode etc.
HTML
<select class="example">
<option value="1" data-value="A">One</option>
<option value="2" data-value="B">Two</option>
<option value="3" data-value="C">Three</option>
<option value="4" data-value="D">Four</option>
</select>
JS
$('select.example').change(function() {
var other_val = $('select.example option[value="' + $(this).val() + '"]').data('value');
console.log(other_val);
});
Using toPrecision method:
var a = 1.2345
a.toPrecision(2)
// result "1.2"
You can't use variable names to bind columns or other system objects, you need dynamic sql
DECLARE @value varchar(10)
SET @value = 'intStep'
DECLARE @sqlText nvarchar(1000);
SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)
Put your code in a method.
Try this:
public class MyClass {
public static void main(String[] args) {
UserInput input = new UserInput();
input.name();
}
}
Then "run" the class from your IDE
For sync calls you can use the method below:
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
Just do the following change
echo off
cls
echo Would you like to do a backup?
pause
copy "\\My_Servers_IP\Shared Drive\FolderName\*" C:\TEST_BACKUP_FOLDER
pause
You can use this extensions
public static class JsonExtensions
{
public static T ToObject<T>(this string jsonText)
{
return JsonConvert.DeserializeObject<T>(jsonText);
}
public static string ToJson<T>(this T obj)
{
return JsonConvert.SerializeObject(obj);
}
}
All these answers are correct, but I had to also check if the string contains other characters and Hebrew letters so I simply used:
if (!str.match(/^[\d]+$/)) {
//contains other characters as well
}
To install TF on windows, follow the below-mentioned steps:
conda create --name tensorflow python=3.5
activate tensorflow
conda install jupyter
conda install scipy
pip install tensorflow-gpu
Use pip install tensorflow
in place of pip install tensorflow-gpu
, in case if you want to install CPU only version of TF.
Note: This installation has been tested with Anaconda Python 3.5 (64 bit). I have also tried the same installation steps with (a) Anaconda Python 3.6 (32 bit), (b) Anaconda Python 3.6 (64 bit), and (c) Anaconda Python 3.5 (32 bit), but all of them (i.e. (a), (b) and (c) ) failed.
Actually you can do it the following way as well.
Suppose your ComboBox name is comboBoxA
. Then its value can be gotten as:
string combo = comboBoxA.SelectedValue.ToString();
I think it's now supported since your question is five years old.

Another way is to set your line-height in the container div, and align your image to that using vertical-align: middle.
html:
<div class="container"><img></div>
css:
.container {
width: 200px; /* or whatever you want */
height: 200px; /* or whatever you want */
line-height: 200px; /* or whatever you want, should match height */
text-align: center;
}
.container > img {
vertical-align: middle;
}
It's off the top of my head. But I've used this before - it should do the trick. Works for older browsers as well.
Generally this error arise when we send header after echoing or printing. If this error arise on a specific page then make sure that page is not echoing anything before calling to start_session()
.
Example of Unpredictable Error:
<?php //a white-space before <?php also send for output and arise error
session_start();
session_regenerate_id();
//your page content
One more example:
<?php
includes 'functions.php';
?> <!-- This new line will also arise error -->
<?php
session_start();
session_regenerate_id();
//your page content
Conclusion: Do not output any character before calling session_start()
or header()
functions not even a white-space or new-line
This can also happen because github has recently renamed the default branch from "master" to "main" ( https://github.com/github/renaming ), so if you just created a new repository on github use git push origin main
instead of git push origin master
I solved this issue by:
I agree with everything that is said already, just trying to put some other words on it.
A delegate can be seen as a placeholder for a/some method(s).
By defining a delegate, you are saying to the user of your class, "Please feel free to assign, any method that matches this signature, to the delegate and it will be called each time my delegate is called".
Typical use is of course events. All the OnEventX delegate to the methods the user defines.
Delegates are useful to offer to the user of your objects some ability to customize their behavior. Most of the time, you can use other ways to achieve the same purpose and I do not believe you can ever be forced to create delegates. It is just the easiest way in some situations to get the thing done.
Using Guava library, another option is to convert the Iterable
to a List
.
List list = Lists.newArrayList(some_iterator);
int count = list.size();
Use this if you need also to access the elements of the iterator after getting its size. By using Iterators.size()
you no longer can access the iterated elements.
They both represent floating point numbers. A FLOAT
is for single-precision, while a DOUBLE
is for double-precision numbers.
MySQL uses four bytes for single-precision values and eight bytes for double-precision values.
There is a big difference from floating point numbers and decimal (numeric) numbers, which you can use with the DECIMAL
data type. This is used to store exact numeric data values, unlike floating point numbers, where it is important to preserve exact precision, for example with monetary data.
Using requests and json makes it simple.
json.loads
functionRequests module provides you useful function to loop for success and failure.
if(Response.ok)
: will help help you determine if your API call is successful (Response code - 200)
Response.raise_for_status()
will help you fetch the http code that is returned from the API.
Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.
#Python 2.7.6
#RestfulClient.py
import requests
from requests.auth import HTTPDigestAuth
import json
# Replace with the correct URL
url = "http://api_url"
# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)
# For successful API call, response code will be 200 (OK)
if(myResponse.ok):
# Loading the response data into a dict variable
# json.loads takes in only binary or string variables so using content to fetch binary content
# Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
jData = json.loads(myResponse.content)
print("The response contains {0} properties".format(len(jData)))
print("\n")
for key in jData:
print key + " : " + jData[key]
else:
# If response code is not ok (200), print the resulting http error code with description
myResponse.raise_for_status()

Try this:
@Repository
@Qualifier("birthdayRepository")
public interface BirthdayRepository extends MongoRepository<BirthDay,String> {
public BirthDay findByFirstName(String firstName);
}
And when injecting the bean:
@Autowired

private BirthdayRepository repository;
If not, check your CoponentScan in your config.
This worked for me:
let task: URLSessionDataTask = session.dataTask(with: request as URLRequest) { (data, response, error) -> Void in
...
The key was adding in the URLSessionDataTask
type declaration.
The reason is that when you use lazy load, the session is closed.
There are two solutions.
Don't use lazy load.
Set lazy=false
in XML or Set @OneToMany(fetch = FetchType.EAGER)
In annotation.
Use lazy load.
Set lazy=true
in XML or Set @OneToMany(fetch = FetchType.LAZY)
In annotation.
and add OpenSessionInViewFilter filter
in your web.xml

Near the top of the code with the Public Workshop(), I am assumeing this bit,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
suitButton = new JCheckBox("Denim Jeans");
suitButton.setMnemonic(KeyEvent.VK_U);
should maybe be,
suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);
denimjeansButton = new JCheckBox("Denim Jeans");
denimjeansButton.setMnemonic(KeyEvent.VK_U);
On Ubuntu 14.04 I installed it from apt-get and it worked fine:
sudo apt-get install python-beautifulsoup
Then just do:
from BeautifulSoup import BeautifulSoup
It should be $_COOKIE['name']
, not $_COOKIE('name')
$_COOKIE
is an array, not a function.
I am a VIMer. I can do some rare Hex edits with:
:%!xxd
to switch into hex mode
:%!xxd -r
to exit from hex mode
But I strongly recommend ht
apt-cache show ht
Package: ht
Version: 2.0.18-1
Installed-Size: 1780
Maintainer: Alexander Reichle-Schmehl <[email protected]>
Homepage: http://hte.sourceforge.net/
Note: The package is called ht
, whereas the executable is named hte
after the package was installed.
Swift uses the same cocoa-touch API. You can call all the same methods, but they will use Swift's syntax. In this example you can do something like this:
self.simpleLabel.text = "message"
Note the setText method isn't available. Setting the label's text with = will automatically call the setter in swift.
Don't forget to take into consideration the global flag in your regexp :
var reg = /abc/g;
!!'abcdefghi'.match(reg); // => true
!!'abcdefghi'.match(reg); // => true
reg.test('abcdefghi'); // => true
reg.test('abcdefghi'); // => false <=
This is because Regexp keeps track of the lastIndex when a new match is found.
You can use history.goBack()
in functional component. Just like this.
import { useHistory } from 'react-router';
const component = () => {
const history = useHistory();
return (
<button onClick={() => history.goBack()}>Previous</button>
)
}
All the 3 first ways are identical. You have make sure that if t
is a matrix you add .
before using multiplication or the power.
for matrix:
t= [1 2 3;2 3 4;3 4 5];
tp=t.*t;
x=exp(-(t.^2));
y=exp(-(t.*t));
z=exp(-(tp));
gives the results:
x =
0.3679 0.0183 0.0001
0.0183 0.0001 0.0000
0.0001 0.0000 0.0000
y =
0.3679 0.0183 0.0001
0.0183 0.0001 0.0000
0.0001 0.0000 0.0000
z=
0.3679 0.0183 0.0001
0.0183 0.0001 0.0000
0.0001 0.0000 0.0000
And using a scalar:
p=3;
pp=p^2;
x=exp(-(p^2));
y=exp(-(p*p));
z=exp(-pp);
gives the results:
x =
1.2341e-004
y =
1.2341e-004
z =
1.2341e-004
If you want all the bars to get the same color (fill
), you can easily add it inside geom_bar
.
ggplot(data=df, aes(x=c1+c2/2, y=c3)) +
geom_bar(stat="identity", width=c2, fill = "#FF6666")
Add fill = the_name_of_your_var
inside aes
to change the colors depending of the variable :
c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2)
Use scale_fill_manual()
if you want to manually the change of colors.
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2) +
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))
You have to cast it to another type of pointer before doing pointer arithmetic.
var myItem = myList.Find(item => item.property == "something");
Iframes is no longer needed for uploading files through ajax. I've recently done it by myself. Check out these pages:
Using HTML5 file uploads with AJAX and jQuery
http://dev.w3.org/2006/webapi/FileAPI/#FileReader-interface
Updated the answer and cleaned it up. Use the getSize function to check size or use getType function to check types. Added progressbar html and css code.
var Upload = function (file) {
this.file = file;
};
Upload.prototype.getType = function() {
return this.file.type;
};
Upload.prototype.getSize = function() {
return this.file.size;
};
Upload.prototype.getName = function() {
return this.file.name;
};
Upload.prototype.doUpload = function () {
var that = this;
var formData = new FormData();
// add assoc key values, this will be posts values
formData.append("file", this.file, this.getName());
formData.append("upload_file", true);
$.ajax({
type: "POST",
url: "script",
xhr: function () {
var myXhr = $.ajaxSettings.xhr();
if (myXhr.upload) {
myXhr.upload.addEventListener('progress', that.progressHandling, false);
}
return myXhr;
},
success: function (data) {
// your callback here
},
error: function (error) {
// handle error
},
async: true,
data: formData,
cache: false,
contentType: false,
processData: false,
timeout: 60000
});
};
Upload.prototype.progressHandling = function (event) {
var percent = 0;
var position = event.loaded || event.position;
var total = event.total;
var progress_bar_id = "#progress-wrp";
if (event.lengthComputable) {
percent = Math.ceil(position / total * 100);
}
// update progressbars classes so it fits your code
$(progress_bar_id + " .progress-bar").css("width", +percent + "%");
$(progress_bar_id + " .status").text(percent + "%");
};
How to use the Upload class
//Change id to your id
$("#ingredient_file").on("change", function (e) {
var file = $(this)[0].files[0];
var upload = new Upload(file);
// maby check size or type here with upload.getSize() and upload.getType()
// execute upload
upload.doUpload();
});
Progressbar html code
<div id="progress-wrp">
<div class="progress-bar"></div>
<div class="status">0%</div>
</div>
Progressbar css code
#progress-wrp {
border: 1px solid #0099CC;
padding: 1px;
position: relative;
height: 30px;
border-radius: 3px;
margin: 10px;

.gitignore will only ignore files that you haven't already added to your repository.
If you did a git add .
, and the file got added to the index, .gitignore won't help you. You'll need to do git rm sites/default/settings.php
to remove it, and then it will be ignored.
The Python 3 version is:
def _get_args_dict(fn, args, kwargs):
args_names = fn.__code__.co_varnames[:fn.__code__.co_argcount]
return {**dict(zip(args_names, args)), **kwargs}
The method returns a dictionary containing both args and kwargs.
Call me lazy but coding a Converter seems like a lot of unnecessary work. I'm using Primefaces and, not having used a plain vanilla JSF2 listbox or dropdown menu before, I just assumed (being lazy) that the widget could handle complex objects, i.e. pass the selected object as is to its corresponding getter/setter like so many other widgets do. I was disappointed to find (after hours of head scratching) that this capability does not exist for this widget type without a Converter. In fact if you supply a setter for the complex object rather than for a String, it fails silently (simply doesn't call the setter, no Exception, no JS error), and I spent a ton of time going through BalusC's excellent troubleshooting tool to find the cause, to no avail since none of those suggestions applied. My conclusion: listbox/menu widget needs adapting that other JSF2 widgets do not. This seems misleading and prone to leading the uninformed developer like myself down a rabbit hole.
In the end I resisted coding a Converter and found through trial and error that if you set the widget value to a complex object, e.g.:
<p:selectOneListbox id="adminEvents" value="#{testBean.selectedEvent}">
... when the user selects an item, the widget can call a String setter for that object, e.g. setSelectedThing(String thingString) {...}
, and the String passed is a JSON String representing the Thing object. I can parse it to determine which object was selected. This feels a little like a hack, but less of a hack than a Converter.
This maybe not the answer to poster's question.But this may helpful to people whose face same situation with me:
The client have two network cards,a wireless one and a normal one.
The ping to server can be succeed.However telnet serverAddress 3306
would fail.
And would complain
Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060)
when try to connect to server.So I forbidden the normal network adapters.
And tried telnet serverAddress 3306
it works.And then it work when connect to MySQL server.
SPSS can also read .dta files and export them to .csv, but that costs money. PSPP, an open source version of SPSS, which is rough, might also be able to read/export .dta files.

As my purpose is to get an empty version of the test database to import data from an external previous current active source (Access database) once all is fine tuned. I found that using DBCC CloneDatabase with Verify_CloneDB option fits perfectly.
For me, setting JAVA_HOME did the trick (instead of unsetting, as in another answer given here). Either in Windows:
set JAVA_HOME="C:\Program Files\Java\jre7\"
Or inside R:
Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jre7\\")
But what's probably the best solution (since rJava 0.9-4) is overriding within R the Windows JAVA_HOME setting altogether:
options(java.home="C:\\Program Files\\Java\\jre7\\")
library(rJava)

Possibly not cross browser but I managed get this: http://jsfiddle.net/QexkH/
basically it requires a fixed height header and footer. and it absolute positions the table.
table {
width: 50%;
height: 50%;
border-spacing: 0;
position:absolute;
}
td {
border: 1px solid black;
}
#content {
position:absolute;
width:100%;
left:0px;
top:20px;
bottom:20px;
overflow: hidden;
}
Though not POSIX, bash 4 has the &>
