To set white colour of the image(arrow icon) on the button, we're using:

let imageOnButton = UIImage(named: "navForwardArrow")?.imageWithColor(color: UIColor.white)
button.setImage(imageOnButton, for: .normal)

Known issue: The icon looses its white colour while the button is pressed.

Screenshot:

swift version:

var button = UIButton()

newGameButton.setTitle("????? ????", for: .normal)
newGameButton.setImage(UIImage(named: "energi"), for: .normal)
newGameButton.backgroundColor = .blue
newGameButton.imageEdgeInsets.left = -50

UIButton extension with Swift 3+ syntax:

extension UIButton {
    func setBackgroundColor(color: UIColor, forState: UIControlState) {
        UIGraphicsBeginImageContext(CGSize(width: 1, height: 1))
        UIGraphicsGetCurrentContext()!.setFillColor(color.cgColor)
        UIGraphicsGetCurrentContext()!.fill(CGRect(x: 0, y: 0, width: 1, height: 1))
        let colorImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        self.setBackgroundImage(colorImage, for: forState)
    }}

Use it like:

YourButton.setBackgroundColor(color: UIColor.white, forState: .highlighted)

Original Answer: https://stackoverflow.com/a/30604658/3659227

It turns out that

[buttonObj sendActionsForControlEvents:UIControlEventTouchUpInside];

got me exactly what I needed, in this case.

EDIT: Don't forget to do this in the main thread, to get results similar to a user-press.

For Swift 3:

buttonObj.sendActions(for: .touchUpInside)

With the help of Tim C's answer, I was able to create an extension on UIButton using Swift that allows you to specify the image frame by using the .setImage() function with an extra frame parameter

extension UIButton{

    func setImage(image: UIImage?, inFrame frame: CGRect?, forState state: UIControlState){
        self.setImage(image, forState: state)

        if let frame = frame{
            self.imageEdgeInsets = UIEdgeInsets(
                top: frame.minY - self.frame.minY,
                left: frame.minX - self.frame.minX,
                bottom: self.frame.maxY - frame.maxY,
                right: self.frame.maxX - frame.maxX
            )
        }
    }

}

Using this, if you wanted to set the frame of a UIButton to CGRectMake(0, 0, 64, 64), and set the image of it to myImage with a frame of CGRectMake(8, 8, 48, 48), you could use

let button: UIButton = UIButton(frame: CGRectMake(0, 0, 64, 64))
button.setImage(
    myImage,
    inFrame: CGRectMake(8, 8, 48, 48),
    forState: UIControlState.Normal
)

If you have a loop of buttons like me you can try something like this

var buttonTags:[Int:String]? // can be [Int:Any]
let myArray = [0:"a",1:"b"]
for (index,value) in myArray {

     let button = // Create a button

     buttonTags?[index] = myArray[index]
     button.tag = index
     button.addTarget(self, action: #selector(buttonAction(_:)), for: .touchDown)

}
@objc func buttonAction(_ sender:UIButton) {

    let myString = buttonTags[sender.tag]

}

Try this!!

 override func viewDidLoad() {
   super.viewDidLoad()

   var button = UIButton.buttonWithType(.Custom) as UIButton
   button.frame = CGRectMake(160, 100, 200,40)

   button.layer.cornerRadius =5.0
   button.layer.borderColor = UIColor.redColor().CGColor
   button.layer.borderWidth = 2.0

   button.setImage(UIImage(named:"Placeholder.png"), forState: .Normal)
   button.addTarget(self, action: "OnClickroundButton", forControlEvents: .TouchUpInside)
   button.clipsToBounds = true

   view.addSubview(button)
}
    func OnClickroundButton() {
   NSLog(@"roundButton Method Called");
}

Updated answer of Jesse Crossen for Swift 4:

extension UIButton {
    func alignVertical(spacing: CGFloat = 6.0) {
        guard let imageSize = self.imageView?.image?.size,
            let text = self.titleLabel?.text,
            let font = self.titleLabel?.font
            else { return }
        self.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -imageSize.width, bottom: -(imageSize.height + spacing), right: 0.0)
        let labelString = NSString(string: text)
        let titleSize = labelString.size(withAttributes: [kCTFontAttributeName as NSAttributedStringKey: font])
        self.imageEdgeInsets = UIEdgeInsets(top: -(titleSize.height + spacing), left: 0.0, bottom: 0.0, right: -titleSize.width)
        let edgeOffset = abs(titleSize.height - imageSize.height) / 2.0;
        self.contentEdgeInsets = UIEdgeInsets(top: edgeOffset, left: 0.0, bottom: edgeOffset, right: 0.0)
    }
}

Use this way:

override func viewDidLayoutSubviews() {
    button.alignVertical()
}

Your code should look like below

let image = UIImage(named: "name") as UIImage?
let button   = UIButton(type: UIButtonType.Custom) as UIButton
button.frame = CGRectMake(100, 100, 100, 100)
button.setImage(image, forState: .Normal)
button.addTarget(self, action: "btnTouched:", forControlEvents:.TouchUpInside)
self.view.addSubview(button)

Tarun's code doesnt work on iOS7, since the UITableViewCell structure changed and now he would get "UITableViewCellScrollView" instead.

This post Getting UITableViewCell with superview in iOS 7 has a good solution creating a loop to find the correct parent view, regardless of any future changes in the structure. It boils down to creating a loop:

    UIView *superView = [sender superview];
    UIView *foundSuperView = nil;

    while (nil != superView && nil == foundSuperView) {
        if ([superView isKindOfClass:[UITableViewCell class]]) {
            foundSuperView = superView;
        } else {
            superView = superView.superview;
        }
    }

The link has code for a more reusable solution, but this should work.

Swift 5.0

// Standard State
myButton.setTitle("Title", for: .normal)

In Swift:

Changing the label text color is quite different than changing it for a UIButton. To change the text color for a UIButton use this method:

self.headingButton.setTitleColor(UIColor(red: 107.0/255.0, green: 199.0/255.0, blue: 217.0/255.0), forState: UIControlState.Normal)

How about Constraints? Unlike semanticContentAttribute, they don't change semantics. Something like this perhaps:

 button.rightAnchorconstraint(equalTo: button.rightAnchor).isActive = true

or in Objective-C:

[button.imageView.rightAnchor constraintEqualToAnchor:button.rightAnchor].isActive = YES;

Caveats: Untested, iOS 9+

You can create like this and you can add action also like this....

import UIKit

let myButton = UIButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50))

init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!)
{       super.init(nibName: nibName, bundle: nibBundle) 
        myButton.targetForAction("tappedButton:", withSender: self)
}

func tappedButton(sender: UIButton!)
{ 
     println("tapped button")
}

You can use:

button.titleLabel.font = [UIFont systemFontOfSize:14.0];

In Swift 5.0 and Xcode 10.2

You have two ways to approaches

1) Direct approach

btn.contentHorizontalAlignment = .left

2) SharedClass example (write once and use every ware)

This is your shared class(like this you access all components properties)

import UIKit

class SharedClass: NSObject {

    static let sharedInstance = SharedClass()

    private override init() {

    }
}

//UIButton extension
extension UIButton {
    func btnProperties() {
        contentHorizontalAlignment = .left
    }
}

In your ViewController call like this

button.btnProperties()//This is your button

 CGRect buttonFrame = CGRectMake( x-pos, y-pos, width, height );   //
 CGRectMake(10,5,10,10) 

 UIButton *button = [[UIButton alloc] initWithFrame: buttonFrame];

 button setTitle: @"My Button" forState: UIControlStateNormal];

 [button addTarget:self action:@selector(btnClicked:) 
 forControlEvents:UIControlEventTouchUpInside];

 [button setTitleColor: [UIColor BlueVolor] forState:
 UIControlStateNormal];

 [view addSubview:button];




 -(void)btnClicked {
    // your code }

Don't worry so much framing the button from code, you can do that on the storyboard. This worked for me, one line...more simple.

[self.button setBackgroundImage:[UIImage imageNamed: @"yourPic.png"] forState:UIControlStateNormal];

func setTitleColor(_ color: UIColor?, 
               for state: UIControl.State)

Parameters:

color:
The color of the title to use for the specified state.

state:
The state that uses the specified color. The possible values are described in UIControl.State.

Sample:

let MyButton = UIButton()
MyButton.setTitle("Click Me..!", for: .normal)
MyButton.setTitleColor(.green, for: .normal)

This will be helpful for the right bottom rounded button

HTML :

      <a class="fixedButton" href>
         <div class="roundedFixedBtn"><i class="fa fa-phone"></i></div>
      </a>
    

CSS:

       .fixedButton{
            position: fixed;
            bottom: 0px;
            right: 0px; 
            padding: 20px;
        }
        .roundedFixedBtn{
          height: 60px;
          line-height: 80px;  
          width: 60px;  
          font-size: 2em;
          font-weight: bold;
          border-radius: 50%;
          background-color: #4CAF50;
          color: white;
          text-align: center;
          cursor: pointer;
        }
    

Here is jsfiddle link http://jsfiddle.net/vpthcsx8/11/

I suppose that 255 in 227./255 is perceived as an integer and divide is always return 0

Correct me if I am wrong. By doing

   [button setSelected:YES];

you are clearly changing the state of the buttons as selected. So naturally by the code you have provided the image will that for the selected state in your case checked.png

Swift 3: You can create a UIButton programmatically

either inside a methods scope for example in ViewDidLoad() Be sure to add constraints to the button, otherwise you wont see it

let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.target(forAction: #selector(buttonAction), withSender: self)
//button.backgroundColor etc

view.addSubview(button)

@objc func buttonAction() {
   //some Action
}

or outside your scope as global variable to access it from anywhere in your module

let button: UIButton = {
   let b = UIButton()
   b.translatesAutoresizingMaskIntoConstraints = false
   //b.backgroundColor etc
   return b
}()

and then you setup the constraints

func setupButtonView() {
   view.addSubview(button)
   button.widthAnchor.constraint(equalToConstant: 40).isActive = true
   button.heightAnchor.constraint(equalToConstant: 40).isActive = true
   // etc

}

For iOS 6 and above, use the following to allow multiple lines:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
// you probably want to center it
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if you want to 
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

For iOS 5 and below use the following to allow multiple lines:

button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
// you probably want to center it
button.titleLabel.textAlignment = UITextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

2017, for iOS9 forward,

generally, just do these two things:

1. choose "Attributed Text"
2. on the "Line Break" popup select "Word Wrap"

For Swift 3 (even shorter code)

let button = UIButton(type: UIButtonType.custom)
button.frame = CGRect(x: 0, y: 0, width: 200.0, height: 40.0)
button.addTarget(nil, action: #selector(tapButton(_:)), for: UIControlEvents.touchUpInside)
button.tintColor = UIColor.white
button.backgroundColor = UIColor.red
button.setBackgroundImage(UIImage(named: "ImageName"), for: UIControlState.normal)
button.setTitle("MyTitle", for: UIControlState.normal)
button.isEnabled = true

func tapButton(sender: UIButton) {

}

In Apple's Accessory sample the following method is used:

[button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

Then in touch handler touch coordinate retrieved and index path is calculated from that coordinate:

- (void)checkButtonTapped:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    if (indexPath != nil)
    {
     ...
    }
}

Swift:

The important thing here is when will you call the .sizeToFit() , it should be after setting the text to display so it can read the size needed, if you later update text, then call it again.

var button = UIButton()
button.setTitle("Length of this text determines size", forState: UIControlState.Normal)
button.sizeToFit()
self.view.addSubview(button)

You can use following code:

sendButton.enabled = YES;
sendButton.alpha = 1.0;

or

sendButton.enabled = NO;
sendButton.alpha = 0.5;

You can use this subclass of UIButton to customize UIButton as per your needs.

visit this github repo for reference

class RoundedRectButton: UIButton {

    var selectedState: Bool = false

    override func awakeFromNib() {
        super.awakeFromNib()
        layer.borderWidth = 2 / UIScreen.main.nativeScale
        layer.borderColor = UIColor.white.cgColor
        contentEdgeInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    }


    override func layoutSubviews(){
        super.layoutSubviews()
        layer.cornerRadius = frame.height / 2
        backgroundColor = selectedState ? UIColor.white : UIColor.clear
        self.titleLabel?.textColor = selectedState ? UIColor.green : UIColor.white
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        selectedState = !selectedState
        self.layoutSubviews()
    }
}

Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.

myButton.titleLabel?.font =  UIFont(name: YourfontName, size: 20)

However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.

One more possible cause is this:

If you attempt to set the button's title in the (id)initWithNibName: ... method, then you're button property will still be nil. It hasn't yet been assigned to the UIButton.

You must be sure that you're setting your buttons in a method like (void)viewWillLoad or (void)viewWillAppear, but you probably don't want to set them as late as (void)viewDidAppear.

You can use -[UIButton setTitleColor:forState:] to do this.

Example:

Objective-C

[buttonName setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

Swift 2

buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

Swift 3

buttonName.setTitleColor(UIColor.white, for: .normal)

Let's say in Swift 4 you have a button set up for a segue as an IBAction like this @IBAction func nextLevel(_ sender: UIButton) {} and you have other actions occurring within your app (i.e. a timer, gamePlay, etc.). Rather than disabling the segue button, you might want to give your user the option to use that segue while the other actions are still occurring and WITHOUT CRASHING THE APP. Here's how:

var appMode = 0

@IBAction func mySegue(_ sender: UIButton) {

    if appMode == 1 {  // avoid crash if button pressed during other app actions and/or conditions
        let conflictingAction = sender as UIButton
        conflictingAction.isEnabled = false
    }
}

Please note that you will likely have other conditions within if appMode == 0 and/or if appMode == 1 that will still occur and NOT conflict with the mySegue button. Thus, AVOIDING A CRASH.

Try UISegmentedControl. It behaves similarly to radio buttons -- presents an array of choices and lets the user pick 1.

Swift 3:

        static func imageFromColor(color: UIColor, width: CGFloat, height: CGFloat) -> UIImage {
            let rect = CGRect(x: 0, y: 0, width: width, height: height)
            UIGraphicsBeginImageContext(rect.size)
            let context = UIGraphicsGetCurrentContext()!
            context.setFillColor(color.cgColor)
            context.fill(rect)
            let img = UIGraphicsGetImageFromCurrentImageContext()!
            UIGraphicsEndImageContext()
            return img
        }

        let button = UIButton(type: .system)
        let image = imageFromColor(color: .red, width: 
        button.frame.size.width, height: button.frame.size.height)
        button.setBackgroundImage(image, for: .normal)

To change your background color of the botton use:

yourBtn.backgroundColor = UIColor.black

An alternative answer which sets a border too (making it more like a button) is here ... How to set rectangle border for custom type UIButton

Assuming that btn refers to a UIButton, to change a multi-line caption to be centered horizontally, you can use the following statement in iOS 6 or later:

self.btn.titleLabel.textAlignment = NSTextAlignmentCenter;

Swift 4.x

extension UIButton {
    func centerTextAndImage(spacing: CGFloat) {
        let insetAmount = spacing / 2
        let writingDirection = UIApplication.shared.userInterfaceLayoutDirection
        let factor: CGFloat = writingDirection == .leftToRight ? 1 : -1

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: -insetAmount*factor, bottom: 0, right: insetAmount*factor)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount*factor, bottom: 0, right: -insetAmount*factor)
        self.contentEdgeInsets = UIEdgeInsets(top: 0, left: insetAmount, bottom: 0, right: insetAmount)
    }
}

Usage:

button.centerTextAndImage(spacing: 10.0)

While the question involves Git for Windows, this seems to be the top result even when searching for Visual Studio Tools For Git (extension in VS 2012, native support in VS 2013).

Using the solutions above as a guide I determined that Visual Studio Git Tools makes moving repos (or even entire directory structure for all repos) locally very easy.

1) Close Visual Studio. 2) Move the Repo folder(s) to new location. 3) Open Visual Studio. Open Team Explorer. Switch to "Connect" view (plug icon at top). 3a) If Repos still show old path, click Refresh to force an update. 4) Repos that were moved locally should no longer be showing in "Local Git Repositories". 5) Click Add (not new or clone) and select the repo folder to add.

In step 5 you really are just providing a search path and the search automatically includes all subfolders. If you have multiple repos organized under a single root (independent repos just having the same parent folder) then selecting the parent will include all repos found below that.

Example: E:\Repos\RepoA E:\Repos\RepoB E:\Repos\RepoC

In Visual Studio Team Explorer [Add] > "E:\Repos\" > [Add] will return all three to the Local Repositories.

var string = 'a,b,c,d',
    strx   = string.split(',');
    array  = [];

array = array.concat(strx);
// ["a","b","c","d"]

There are several methods you could use that exist in the System.IO namespace:

Directory.GetLogicalDrives() // Returns an array of strings like "c:\"
Path.GetInvalidFileNameChars() // Returns an array of characters that cannot be used in a file name
Path.GetInvalidPathChars() // Returns an array of characters that cannot be used in a path.

As suggested you could then do this:

bool IsValidFilename(string testName) {
    string regexString = "[" + Regex.Escape(Path.GetInvalidPathChars()) + "]";
    Regex containsABadCharacter = new Regex(regexString);
    if (containsABadCharacter.IsMatch(testName)) {
        return false;
    }

    // Check for drive
    string pathRoot = Path.GetPathRoot(testName);
    if (Directory.GetLogicalDrives().Contains(pathRoot)) {
        // etc
    }

    // other checks for UNC, drive-path format, etc

    return true;
}

Running iisreset in a command window fixed it for me.

On server-side it will be not as accurate as with JavaScript. Meanwhile, sometimes it is required to solve such task. Just to share the possible solution in this case I write this answer.

If you need to determine user's time zone it could be done via Geo-IP services. Some of them providing timezone. For example, this one (http://smart-ip.net/geoip-api) could help:

<?php
$ip     = $_SERVER['REMOTE_ADDR']; // means we got user's IP address 
$json   = file_get_contents( 'http://smart-ip.net/geoip-json/' . $ip); // this one service we gonna use to obtain timezone by IP
// maybe it's good to add some checks (if/else you've got an answer and if json could be decoded, etc.)
$ipData = json_decode( $json, true);

if ($ipData['timezone']) {
    $tz = new DateTimeZone( $ipData['timezone']);
    $now = new DateTime( 'now', $tz); // DateTime object corellated to user's timezone
} else {
   // we can't determine a timezone - do something else...
}

In my case, I want to add a column to a Primary key (column4). I used this script to add column4

ALTER TABLE TableA
DROP CONSTRAINT [PK_TableA]

ALTER TABLE TableA
ADD CONSTRAINT [PK_TableA] PRIMARY KEY (
    [column1] ASC,
    [column2] ASC, 
    [column3] ASC,
    [column4] ASC
)

With python 3 you can use list_a[filter] to get True values. To get False values use list_a[~filter]

if( myVariable ) 
{ 
    //mayVariable is not : 
    //null 
    //undefined 
    //NaN 
    //empty string ("") 
    //0 
    //false 
}

The Back button wasn't working for me as well, but I figured out that the problem was that I had html content inside my main page, in the ui-view element.

i.e.

<div ui-view>
     <h1> Hey Kids! </h1>
     <!-- More content -->
</div>

So I moved the content into a new .html file, and marked it as a template in the .js file with the routes.

i.e.

   .state("parent.mystuff", {
        url: "/mystuff",
        controller: 'myStuffCtrl',
        templateUrl: "myStuff.html"
    })

Here is an effective solution from didi to solve this problem, Since this bug is very common and difficult to find the cause, It looks more like a system problem, Why can't we ignore it directly?Of course we can ignore it, Here is the sample code:

final Thread.UncaughtExceptionHandler defaultUncaughtExceptionHandler = 
        Thread.getDefaultUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    @Override
    public void uncaughtException(Thread t, Throwable e) {
        if (t.getName().equals("FinalizerWatchdogDaemon") && e instanceof TimeoutException) {
        } else {
            defaultUncaughtExceptionHandler.uncaughtException(t, e);
        }
    }
});

By setting a special default uncaught exception handler, application can change the way in which uncaught exceptions are handled for those threads that would already accept whatever default behavior the system provided. When an uncaught TimeoutException is thrown from a thread named FinalizerWatchdogDaemon, this special handler will block the handler chain, the system handler will not be called, so crash will be avoided.

Through practice, no other bad effects were found. The GC system is still working, timeouts are alleviated as CPU usage decreases.

If you application is a Windows GUI application then using the code below to do the waiting is not ideal as messages for your application will not be getting processing. To the user it will look like your application has hung.

WaitForSingleObject(&processInfo.hProcess, INFINITE)

Something like the untested code below might be better as it will keep processing the windows message queue and your application will remain responsive:

//-- wait for the process to finish
while (true)
{
  //-- see if the task has terminated
  DWORD dwExitCode = WaitForSingleObject(ProcessInfo.hProcess, 0);

  if (   (dwExitCode == WAIT_FAILED   )
      || (dwExitCode == WAIT_OBJECT_0 )
      || (dwExitCode == WAIT_ABANDONED) )
  {
    DWORD dwExitCode;

    //-- get the process exit code
    GetExitCodeProcess(ProcessInfo.hProcess, &dwExitCode);

    //-- the task has ended so close the handle
    CloseHandle(ProcessInfo.hThread);
    CloseHandle(ProcessInfo.hProcess);

    //-- save the exit code
    lExitCode = dwExitCode;

    return;
  }
  else
  {
    //-- see if there are any message that need to be processed
    while (PeekMessage(&message.msg, 0, 0, 0, PM_NOREMOVE))
    {
      if (message.msg.message == WM_QUIT)
      {
        return;
      }

      //-- process the message queue
      if (GetMessage(&message.msg, 0, 0, 0))
      {
        //-- process the message
        TranslateMessage(&pMessage->msg);
        DispatchMessage(&pMessage->msg);
      }
    }
  }
}

A simple function to get the history similar to unix/bash version.

Hope it helps some new folks.

def ipyhistory(lastn=None):
    """
    param: lastn Defaults to None i.e full history. If specified then returns lastn records from history.
           Also takes -ve sequence for first n history records.
    """
    import readline
    assert lastn is None or isinstance(lastn, int), "Only integers are allowed."
    hlen = readline.get_current_history_length()
    is_neg = lastn is not None and lastn < 0
    if not is_neg:
        flen = len(str(hlen)) if not lastn else len(str(lastn))
        for r in range(1,hlen+1) if not lastn else range(1, hlen+1)[-lastn:]:
            print(": ".join([str(r if not lastn else r + lastn - hlen ).rjust(flen), readline.get_history_item(r)]))
    else:
        flen = len(str(-hlen))
        for r in range(1, -lastn + 1):
            print(": ".join([str(r).rjust(flen), readline.get_history_item(r)]))

Snippet: Tested with Python3. Let me know if there are any glitches with python2. Samples:

Full History : ipyhistory()

Last 10 History: ipyhistory(10)

First 10 History: ipyhistory(-10)

Hope it helps fellas.

Faced the same issue and resolved by upgrading my Maven from 3.0.4 to 3.1.1. Please try with v3.1.1 or any higher version if available

Add this for pages not currently on your site...

ErrorDocument 404 http://example.com/

Along with your Redirect 301 / http://www.thenewdomain.com/ that should cover all the bases...

Good luck!

Actually, you can also do it with the iteration method. Because sometimes we might need to use the iteration method instead of the built-in epochs method to visualize the training results after each iteration.

history = [] #Creating a empty list for holding the loss later
for iteration in range(1, 3):
    print()
    print('-' * 50)
    print('Iteration', iteration)
    result = model.fit(X, y, batch_size=128, nb_epoch=1) #Obtaining the loss after each training
    history.append(result.history['loss']) #Now append the loss after the training to the list.
    start_index = random.randint(0, len(text) - maxlen - 1)
print(history)

This way allows you to get the loss you want while maintaining your iteration method.

Running assembly Code on Mac is just 3 steps away from you. It could be done using XCODE but better is to use NASM Command Line Tool. For My Ease I have already installed Xcode, if you have Xcode installed its good.

But You can do it without XCode as well.

Just Follow:

1. First Install NASM using Homebrew brew install nasm
2. convert .asm file into Obj File using this command nasm -f macho64 myFile.asm
3. Run Obj File to see OutPut using command ld -macosx_version_min 10.7.0 -lSystem -o OutPutFile myFile.o && ./64

Simple Text File named myFile.asm is written below for your convenience.

global start
section .text

start:
    mov     rax, 0x2000004 ; write
    mov     rdi, 1 ; stdout
    mov     rsi, msg
    mov     rdx, msg.len
    syscall

    mov     rax, 0x2000001 ; exit
    mov     rdi, 0
    syscall

section .data

msg:    db      "Assalam O Alaikum Dear", 10
.len:   equ     $ - msg

Use extension methods. Replace NameOfContext with the name of your object context.

public static class Extensions{
   public static IQueryable<Company> CompleteCompanies(this NameOfContext context){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country") ;
     }

     public static Company CompanyById(this NameOfContext context, int companyID){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country")
             .FirstOrDefault(c => c.Id == companyID) ;
      }

}

Then your code becomes

     Company company = 
          context.CompleteCompanies().FirstOrDefault(c => c.Id == companyID);

     //or if you want even more
     Company company = 
          context.CompanyById(companyID);

Your cases does not have a return value.

getButtons().get(i).setText("§");

In-line-if is Ternary operation all ternary operations must have return value. That variable is likely void and does not return anything and it is not returning to a variable. Example:

int i = 40;
String value = (i < 20) ? "it is too low" : "that is larger than 20";

for your case you just need an if statement.

if (compareChar(curChar, toChar("0"))) { getButtons().get(i).setText("§"); }

Also side note you should use curly braces it makes the code more readable and declares scope.

I would imagine that this would be covered by CSS Tables, a specification which, while mentioned on the CSS homepage, appears to currently be at a state of "not yet published in any form"

In practical terms, you can't achieve this at present.

I would use the simple code snippet from CSS-Tricks.com:

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

The hyphen is usually a normal character in regular expressions. Only if it’s in a character class and between two other characters does it take a special meaning.

Thus:

• [-] matches a hyphen.
• [abc-] matches a, b, c or a hyphen.
• [-abc] matches a, b, c or a hyphen.
• [ab-d] matches a, b, c or d (only here the hyphen denotes a character range).

I just managed to fix this. I followed Adams instructions but it still would not work so I kept digging and did this on top of Adams instructions:

I went to Module Settings and in the Paths tab under Compiler output I selected Inherit project compile output path. I am running 0.3.0

In the end you have to implement this around Enum.GetNames:

public bool TryParseEnum<T>(string str, bool caseSensitive, out T value) where T : struct {
    // Can't make this a type constraint...
    if (!typeof(T).IsEnum) {
        throw new ArgumentException("Type parameter must be an enum");
    }
    var names = Enum.GetNames(typeof(T));
    value = (Enum.GetValues(typeof(T)) as T[])[0];  // For want of a better default
    foreach (var name in names) {
        if (String.Equals(name, str, caseSensitive ? StringComparison.Ordinal : StringComparison.OrdinalIgnoreCase)) {
            value = (T)Enum.Parse(typeof(T), name);
            return true;
        }
    }
    return false;
}

Additional notes:

• Enum.TryParse is included in .NET 4. See here http://msdn.microsoft.com/library/dd991876(VS.100).aspx
• Another approach would be to directly wrap Enum.Parse catching the exception thrown when it fails. This could be faster when a match is found, but will likely to slower if not. Depending on the data you are processing this may or may not be a net improvement.

EDIT: Just seen a better implementation on this, which caches the necessary information: http://damieng.com/blog/2010/10/17/enums-better-syntax-improved-performance-and-tryparse-in-net-3-5

I supose the "opposite" would be to simulate an event. You could use .createEvent()

Following Mozilla's example:

function simulateClick() {
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
  var cb = document.getElementById("checkbox"); 
  var cancelled = !cb.dispatchEvent(evt);
  if(cancelled) {
    // A handler called preventDefault
    alert("cancelled");
  } else {
    // None of the handlers called preventDefault
    alert("not cancelled");
  }
}

Ref: document.createEvent

jQuery has .trigger() so you can trigger events on elements -- sometimes useful.

$('#foo').bind('click', function() {
      alert($(this).text());
});

$('#foo').trigger('click');

Do you plan to have a squared UIView of width: 100 and Height: 100 centered inside the UIView of an UIViewController? If so, you may try one of the 6 following Auto Layout styles (Swift 5 / iOS 12.2):

1. Using NSLayoutConstraint initializer

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    let widthConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    let heightConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    view.addConstraints([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    let widthConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    let heightConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 100).isActive = true
}

2. Using Visual Format Language

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["view": view!, "newView": newView]
    let horizontalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterY, metrics: nil, views: views)
    let verticalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterX, metrics: nil, views: views)
    view.addConstraints(horizontalConstraints)
    view.addConstraints(verticalConstraints)
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["view": view!, "newView": newView]
    let horizontalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterY, metrics: nil, views: views)
    let verticalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[view]-(<=0)-[newView(100)]", options: NSLayoutConstraint.FormatOptions.alignAllCenterX, metrics: nil, views: views)
    NSLayoutConstraint.activate(horizontalConstraints)
    NSLayoutConstraint.activate(verticalConstraints)
}

3. Using a mix of NSLayoutConstraint initializer and Visual Format Language

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    view.addConstraints(widthConstraints)
    view.addConstraints(heightConstraints)
    view.addConstraints([horizontalConstraint, verticalConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let horizontalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
    let verticalConstraint = NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0)
    NSLayoutConstraint.activate(widthConstraints)
    NSLayoutConstraint.activate(heightConstraints)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = false
    let views = ["newView": newView]
    let widthConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    let heightConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:[newView(100)]", options: NSLayoutConstraint.FormatOptions(rawValue: 0), metrics: nil, views: views)
    NSLayoutConstraint.activate(widthConstraints)
    NSLayoutConstraint.activate(heightConstraints)
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
    NSLayoutConstraint(item: newView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true
}

4. Using UIView.AutoresizingMask

Note: Springs and Struts will be translated into corresponding auto layout constraints at runtime.

override func viewDidLoad() {
    let newView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)

    newView.translatesAutoresizingMaskIntoConstraints = true
    newView.center = CGPoint(x: view.bounds.midX, y: view.bounds.midY)
    newView.autoresizingMask = [UIView.AutoresizingMask.flexibleLeftMargin, UIView.AutoresizingMask.flexibleRightMargin, UIView.AutoresizingMask.flexibleTopMargin, UIView.AutoresizingMask.flexibleBottomMargin]
}

5. Using NSLayoutAnchor

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
    let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
    let widthConstraint = newView.widthAnchor.constraint(equalToConstant: 100)
    let heightConstraint = newView.heightAnchor.constraint(equalToConstant: 100)
    view.addConstraints([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
    let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
    let widthConstraint = newView.widthAnchor.constraint(equalToConstant: 100)
    let heightConstraint = newView.heightAnchor.constraint(equalToConstant: 100)
    NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint, widthConstraint, heightConstraint])
}

override func viewDidLoad() {
    let newView = UIView()
    newView.backgroundColor = UIColor.red
    view.addSubview(newView)
    
    newView.translatesAutoresizingMaskIntoConstraints = false
    newView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
    newView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
    newView.widthAnchor.constraint(equalToConstant: 100).isActive = true
    newView.heightAnchor.constraint(equalToConstant: 100).isActive = true
}

6. Using intrinsicContentSize and NSLayoutAnchor

import UIKit

class CustomView: UIView {
    
    override var intrinsicContentSize: CGSize {
        return CGSize(width: 100, height: 100)
    }
    
}

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        let newView = CustomView()
        newView.backgroundColor = UIColor.red
        view.addSubview(newView)
        
        newView.translatesAutoresizingMaskIntoConstraints = false
        let horizontalConstraint = newView.centerXAnchor.constraint(equalTo: view.centerXAnchor)
        let verticalConstraint = newView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
        NSLayoutConstraint.activate([horizontalConstraint, verticalConstraint])
    }
    
}

Result:

Flutter.dev already gives the best answer for it, that is not a bug neither a problem, just config. Just take time read and everything will be solved. Have a nice day everyone.

https://flutter.dev/docs/development/ui/advanced/splash-screen

C++ places the default parameter logic in the calling side, this means that if the default value expression cannot be computed from the calling place, then the default value cannot be used.

Other compilation units normally just include the declaration so default value expressions placed in the definition can be used only in the defining compilation unit itself (and after the definition, i.e. after the compiler sees the default value expressions).

The most useful place is in the declaration (.h) so that all users will see it.

Some people like to add the default value expressions in the implementation too (as a comment):

void foo(int x = 42,
         int y = 21);

void foo(int x /* = 42 */,
         int y /* = 21 */)
{
   ...
}

However, this means duplication and will add the possibility of having the comment out of sync with the code (what's worse than uncommented code? code with misleading comments!).

You may also have a look at some NIO application framework such as:

1. Netty: http://jboss.org/netty
2. Apache Mina: http://mina.apache.org/ or its subproject AsyncWeb: http://mina.apache.org/asyncweb/

On Windows you can also set the environment property OPENSSL_CONF. For example from the commandline you can type:

set OPENSSL_CONF=c:/libs/openssl-0.9.8k/openssl.cnf

to validate it you can type:

echo %OPENSSL_CONF%

You can also set it as part of the computer's environmental variables so all users and services have it available by default. See, for example, Environment variables in Windows NT and How To Manage Environment Variables in Windows XP.

Now you can run openssl commands without having to pass the config location parameter.

To answer your question about downloading files by hand, you can extract the relevant URLs from the SDK Manager's repository manifest:

https://dl-ssl.google.com/android/repository/repository.xml

Just move the entire modal outside of the rest of your code, to the very bottom. It doesn't need to be nested in any other element, other than the body.

<body>
    <!-- All other HTML -->
    <div>
        ...
    </div>

    <!-- Modal -->
    <div class="modal fade" id="myModal">
        ...
    </div>
</body>

Demo

They hint at this solution in the documentation.

Modal Markup Placement
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.

Another problem that may arise relating to receiving an unauthorized is related to the providers used in the authentication setting from IIS. In My case I was experience that problem If I set the Windows Authentication provider as "Negotiate". After I selected "NTLM" option the access was granted.

More Information on Authentication providers

https://docs.microsoft.com/en-us/iis/configuration/system.webserver/security/authentication/windowsauthentication/providers/

I have tried a lot of ways to solve this. But I am failed again and again. Then I did this:

Open Git Bash > go to your directory > paste the git clone https://[email protected]/*******.git after that a command prompt will be shown to give the login credentials. Give the credentials and clone your project.

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

If you only need to look at the cells that are in use you can use:

sub IterateCells()

   For Each Cell in ActiveSheet.UsedRange.Cells
      'do some stuff
   Next

End Sub

that will hit everything in the range from A1 to the last cell with data (the bottom right-most cell)

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

One scenario where final is important, when you want to prevent inheritance of a class, for security reasons. This allows you to make sure that code you are running cannot be overridden by someone.

Another scenario is for optimization: I seem to remember that the Java compiler inlines some function calls from final classes. So, if you call a.x() and a is declared final, we know at compile-time what the code will be and can inline into the calling function. I have no idea whether this is actually done, but with final it is a possibility.

The most commonly know essay written on the topic by a note-worthy source I know of is called Ousterhout's dichotomy. It is highly criticized as being fairly arbitrary and often jokingly refereed to as Ousterhout's false dichotomy. That being said in a discussion about the topic it deserves a citation.

I personally agree that this is a false dichotomy and I wouldn't trust anyone answering this question that proposes to have firm properties as to what defines a scripting language. Comments like "a scripting language must be dynamically typed" are false and comments like "scripting languages must be interpreted" don't even make sense because contrary to popular belief, compilation vs. interpretation is not a property of the language at all.

There are lots of properties that people have mentioned above as roughly matching scripting languages, thankfully most of them properly explaining that this term has no rigorous definition. So I won't duplicate my ideas of what they are here. For my experience people consider a language a scripting language if they can easily write some quick throwaway programs in them without writing much boiler plate. I'm mostly answering to give you the citation to Ousterhout which I don't see here.

Just use

<a [ngClass]="{'disabled': your_condition}"> This a tag is disabled</a>

Example:

 <a [ngClass]="{'disabled': name=='junaid'}"> This a tag is disabled</a>

Adding to what David Whittaker posted, I have created a query that generates the complete table and columns alter statement that will convert each table. It may be a good idea to run

SET SESSION group_concat_max_len = 100000;

first to make sure your group concat doesn't go over the very small limit as seen here.

     SELECT a.table_name, concat('ALTER TABLE ', a.table_schema, '.', a.table_name, ' DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_unicode_ci, ',
        group_concat(distinct(concat(' MODIFY ',  column_name, ' ', column_type, ' CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ', if (is_nullable = 'NO', ' NOT', ''), ' NULL ',
        if (COLUMN_DEFAULT is not null, CONCAT(' DEFAULT \'', COLUMN_DEFAULT, '\''), ''), if (EXTRA != '', CONCAT(' ', EXTRA), '')))), ';') as alter_statement
    FROM information_schema.columns a
    INNER JOIN INFORMATION_SCHEMA.TABLES b ON a.TABLE_CATALOG = b.TABLE_CATALOG
        AND a.TABLE_SCHEMA = b.TABLE_SCHEMA
        AND a.TABLE_NAME = b.TABLE_NAME
        AND b.table_type != 'view'
    WHERE a.table_schema = ? and (collation_name = 'latin1_swedish_ci' or collation_name = 'utf8mb4_general_ci')
    GROUP BY table_name;

A difference here between the previous answer is it was using utf8 instead of ut8mb4 and using t1.data_type with t1.CHARACTER_MAXIMUM_LENGTH didn't work for enums. Also, my query excludes views since those will have to altered separately.

I simply used a Perl script to return all these alters as an array and iterated over them, fixed the columns that were too long (generally they were varchar(256) when the data generally only had 20 characters in them so that was an easy fix).

I found some data was corrupted when altering from latin1 -> utf8mb4. It appeared to be utf8 encoded latin1 characters in columns would get goofed in the conversion. I simply held data from the columns I knew was going to be an issue in memory from before and after the alter and compared them and generated update statements to fix the data.

You can use the GraphRequest class to issue calls to the Facebook Graph API to get user information. See https://developers.facebook.com/docs/android/graph for more info.

You could count the total length of the string first, and pass it to the StringBuilder constructor. And you do not need to convert the Set first.

Set<String> abc = new HashSet<String>();
abc.add("A");
abc.add("B");
abc.add("C");

String separator = ", ";
int total = abc.size() * separator.length();
for (String s : abc) {
    total += s.length();
}

StringBuilder sb = new StringBuilder(total);
for (String s : abc) {
    sb.append(separator).append(s);
}

String result = sb.substring(separator.length()); // remove leading separator

try this

$("input[name=search-mini]").on("search", function() {
 //do something for search
});

Darwind code didn't show the keyboard.

This works for me:

        _searchText.requestFocus();
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(_searchText, InputMethodManager.SHOW_IMPLICIT);

in case the keyboard is not showing, try to force:

        imm.showSoftInput(_searchText, InputMethodManager.SHOW_FORCED);

You can simply use :

if(fieldName.endsWith(","))
{
   StringUtils.chop(fieldName);
}

Android Studio 0.4.0 now includes support for offline:

http://tools.android.com/recent/androidstudio040released

"You can now open the Compiler > Gradle options and enable Offline mode, which will tell Gradle to ignore update-to-date checks"

Updated Nov 2018: Now you can Open preferences, then search for "offline" and in the results select gradle and click "Offline work"

void foo<TOne, TTwo>() 
   where TOne : BaseOne
   where TTwo : BaseTwo

More info here:
http://msdn.microsoft.com/en-us/library/d5x73970.aspx

I fixed similar issues by qutating column name

SELECT * from table_name where "foo" is NULL;

In my case it was just

SELECT id, "foo" from table_name;

without quotes i'v got same error.

You can use CREATE SYNONYM to remote object.

Here is a function to print a PDF from an iframe.

You just need to pass the URL of the PDF to the function. It will create an iframe and trigger print once the PDF is load.

Note that the function doesn't destroy the iframe. Instead, it reuses it each time the function is call. It's hard to destroy the iframe because it is needed until the printing is done, and the print method doesn't has callback support (as far as I know).

printPdf = function (url) {
  var iframe = this._printIframe;
  if (!this._printIframe) {
    iframe = this._printIframe = document.createElement('iframe');
    document.body.appendChild(iframe);

    iframe.style.display = 'none';
    iframe.onload = function() {
      setTimeout(function() {
        iframe.focus();
        iframe.contentWindow.print();
      }, 1);
    };
  }

  iframe.src = url;
}

While trying out the final suggestion above, I discovered an even simpler solution. All I had to do was cache the process handle. As soon as I did that, $process.ExitCode worked correctly. If I didn't cache the process handle, $process.ExitCode was null.

example:

$proc = Start-Process $msbuild -PassThru
$handle = $proc.Handle # cache proc.Handle
$proc.WaitForExit();

if ($proc.ExitCode -ne 0) {
    Write-Warning "$_ exited with status code $($proc.ExitCode)"
}

First you must visit MDN IIFE , Now some points about this

• this is Immediately Invoked Function Expression. So when your javascript file invoked from HTML this function called immediately.
• This prevents accessing variables within the IIFE idiom as well as polluting the global scope.

In my case, I created a new project and when I ran it the first time, it gave me the following error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

So my solution was to go to the Package Manager Console inside the Visual Studio and run:Update-Package

Problem solved!!

Its usually better to whitelist characters you allow, rather than to blacklist characters you don't allow. both from a security standpoint, and from an ease of implementation standpoint.

If you do go down the blacklist route, here is an example, but be warned, the syntax is not simple.

http://groups.google.com/group/regex/browse_thread/thread/0795c1b958561a07

If you want to whitelist all the accent characters, perhaps using unicode ranges would help? Check out this link.

http://www.regular-expressions.info/unicode.html

The XPath turns into this:

Get me all of the div elements that have an id equal to container.

As for getting the first etc, you have two options.

Turn it into a .findElement() - this will just return the first one for you anyway.

or

To explicitly do this in XPath, you'd be looking at:

(//div[@id='container'])[1]

for the first one, for the second etc:

(//div[@id='container'])[2]

Then XPath has a special indexer, called last, which would (you guessed it) get you the last element found:

(//div[@id='container'])[last()]

Worth mentioning that XPath indexers will start from 1 not 0 like they do in most programming languages.

As for getting the parent 'node', well, you can use parent:

//div[@id='container']/parent::*

That would get the div's direct parent.

You could then go further and say I want the first *div* with an id of container, and I want his parent:

(//div[@id='container'])[1]/parent::*

Hope that helps!

If you're looking to capture everything up to "abc":

/^(.*?)abc/

Explanation:

( ) capture the expression inside the parentheses for access using $1, $2, etc.

^ match start of line

.* match anything, ? non-greedily (match the minimum number of characters required) - [1]

[1] The reason why this is needed is that otherwise, in the following string:

whatever whatever something abc something abc

by default, regexes are greedy, meaning it will match as much as possible. Therefore /^.*abc/ would match "whatever whatever something abc something ". Adding the non-greedy quantifier ? makes the regex only match "whatever whatever something ".

The best way is Mikael Eriksson, if ROW_NUMBER() is available to you.

The next best is to join on a query, as per Cularis' answer.

Alternatively, the most simple and straight forward way is a correlated-sub-query in the WHERE clause.

SELECT
  *
FROM
  yourTable AS [data]
WHERE
  DateEntered = (SELECT MAX(DateEntered) FROM yourTable WHERE orderNo = [data].orderNo)

Or...

WHERE
  ID = (SELECT TOP 1 ID FROM yourTable WHERE orderNo = [data].orderNo ORDER BY DateEntered DESC)

VueJS can't pickup your changes to the state if you manipulate arrays like this.

As explained in Common Beginner Gotchas, you should use array methods like push, splice or whatever and never modify the indexes like this a[2] = 2 nor the .length property of an array.

Use Where-Object, like:

Get-ChildItem 'PATH' -recurse -include @("*.tif*","*.jp2","*.pdf") | 
Where-Object { $_.CreationTime -gt "03/01/2013" -and $_.CreationTime -lt "03/31/2013" }
Select-Object FullName, CreationTime, @{Name="Mbytes";Expression={$_.Length/1Kb}}, @{Name="Age";Expression={(((Get-Date) - $_.CreationTime).Days)}} | 
Export-Csv 'PATH\scans.csv'

PERSISTENT, definitive solution

Add this line to your ~/.screenrc

termcapinfo xterm* ti@:te@

Now you can create a screen, and scroll it up/down with your mouse; Like you normally do.

Or you can try ignoreElements() as well

You have to make sure the application is uninstalled.

In your phone, try going to settings/applications and show the list of all your installed applications, then make sure the application is uninstalled for all users (in my case I had uninstalled the application but still for others).

first of all you need to go in your ssh directory
for this type following command in your terminal in mac or whatever you use in window

cd ~/.ssh

now it is in the ssh
here you can find all you ssh key/files related to your all projects. now, type the following command to show you if any ssh key available

ls

this will show you all available ssh, in my case there were two
now, you will need to start an agent to add a ssh in it. For this type following command

eval "$(ssh-agent -s)"

now last but not least you will add a ssh in this agent type following command

ssh-add ~/.ssh/your-ssh

replace

replace your-ssh with your ssh file name which you got a list form second step ls command

From http://codecorner.galanter.net/2012/06/04/solution-for-operation-is-not-valid-due-to-the-current-state-of-the-object-error/

Issue happens because Microsoft Security Update MS11-100 limits number of keys in Forms collection during HTTP POST request. To alleviate this problem you need to increase that number.

This can be done in your application Web.Config in the <appSettings> section (create the section directly under <configuration> if it doesn’t exist). Add 2 lines similar to the lines below to the section:

<add key="aspnet:MaxHttpCollectionKeys" value="2000" />
<add key="aspnet:MaxJsonDeserializerMembers" value="2000" />

The above example set the limit to 2000 keys. This will lift the limitation and the error should go away.

When I was learning venv I created a script to remind me how to activate it.

#!/bin/sh
# init_venv.sh
if [ -d "./bin" ];then
  echo "[info] Ctrl+d to deactivate"
  bash -c ". bin/activate; exec /usr/bin/env bash --rcfile <(echo 'PS1=\"(venv)\${PS1}\"') -i"
fi

This has the advantage that it changes the prompt.

Not 100% sure what you mean:

Trusted_Connection=True;

IS using Windows credentials and is 100% equivalent to:

Integrated Security=SSPI;

or

Integrated Security=true;

If you don't want to use integrated security / trusted connection, you need to specify user id and password explicitly in the connection string (and leave out any reference to Trusted_Connection or Integrated Security)

server=yourservername;database=yourdatabase;user id=YourUser;pwd=TopSecret

Only in this case, the SQL Server authentication mode is used.

If any of these two settings is present (Trusted_Connection=true or Integrated Security=true/SSPI), then the Windows credentials of the current user are used to authenticate against SQL Server and any user iD= setting will be ignored and not used.

For reference, see the Connection Strings site for SQL Server 2005 with lots of samples and explanations.

Using Windows Authentication is the preferred and recommended way of doing things, but it might incur a slight delay since SQL Server would have to authenticate your credentials against Active Directory (typically). I have no idea how much that slight delay might be, and I haven't found any references for that.

Summing up:

If you specify either Trusted_Connection=True; or Integrated Security=SSPI; or Integrated Security=true; in your connection string

==> THEN (and only then) you have Windows Authentication happening. Any user id= setting in the connection string will be ignored.

If you DO NOT specify either of those settings,

==> then you DO NOT have Windows Authentication happening (SQL Authentication mode will be used)

Make sure you don't have any syntax errors in your Dockerfile as this can cause this error as well. A correct example is:

RUN apt-get update \
    && apt-get -y install curl \
    another-package

It was a combination of fixing a syntax error and adding apt-get update that solved the problem for me.

If someone is looking for another option for Git Lab and the options above do not work, then we have another option. For a local installation of Git Lab server, we have found that the approach, below, allows us to include the package dependency. We generated and use an access token to do so.

$ npm install --save-dev https://git.yourdomain.com/userOrGroup/gitLabProjectName/repository/archive.tar.gz?private_token=InsertYourAccessTokenHere

Of course, if one is using an access key this way, it should have a limited set of permissions.

Good luck!

To get it to work on Angular 2.1.1 I had to @Inject window using a string

  constructor( @Inject('Window') private window: Window) { }

and then mock it like this

beforeEach(() => {
  let windowMock: Window = <any>{ };
  TestBed.configureTestingModule({
    providers: [
      ApiUriService,
      { provide: 'Window', useFactory: (() => { return windowMock; }) }
    ]
  });

and in the ordinary @NgModule I provide it like this

{ provide: 'Window', useValue: window }

Using Encoding.Unicode won't accurately decode an ANSI file in the same way that a JPEG decoder won't understand a GIF file.

I'm surprised that Encoding.Default didn't work for the ANSI file if it really was ANSI - if you ever find out exactly which code page Notepad was using, you could use Encoding.GetEncoding(int).

In general, where possible I'd recommend using UTF-8.

You can this structure in Layout.cshtml file

<link href="~/YourCssFolder/YourCssStyle.css" rel="stylesheet" type="text/css" />

I found a solution:

print("My message here");

Yes, an Abstract Class can have a Constructor. You Can Overload as many Constructor as you want in an Abstract Class. These Contractors Can be used to Initialized the initial state of the Objects Extending the Abstract Class. As we know we can't make an object of an Abstract Class because Objects are Created by the "new" keywords and not by the constructors...they are there for only initializing the state of the subclass Objects.

I think this will help : In Controller get the list items and selected value

public ActionResult Edit(int id)
{
    ItemsStore item = itemStoreRepository.FindById(id);
    ViewBag.CategoryId = new SelectList(categoryRepository.Query().Get(), 
                                        "Id", "Name",item.CategoryId);

    // ViewBag to pass values to View and SelectList
    //(get list of items,valuefield,textfield,selectedValue)

    return View(item);
}

and in View

@Html.DropDownList("CategoryId",String.Empty)

I want to share my solution for those who are using react-router-dom v5 since none of these v4 solutions did the work for me.

What solved my problem was installing react-router-scroll-top and put the wrapper in the <App /> like this:

const App = () => (
  <Router>
    <ScrollToTop>
      <App/>
    </ScrollToTop>
  </Router>
)

and that's it! it worked!

The main point of the differences as pointed out @BizApps is that Load event happens right after the ViewState is populated while PreRender event happens later, right before Rendering phase, and after all individual children controls' action event handlers are already executing. Therefore, any modifications done by the controls' actions event handler should be updated in the control hierarchy during PreRender as it happens after.

del won't trigger any dialogs or message boxes. You have a few problems, though:

1. start will just open Explorer which would be useless. You need cd to change the working directory of your batch file (the /D is there so it also works when run from a different drive):

   cd /D %temp%
   

2. You may want to delete directories as well:

   for /d %%D in (*) do rd /s /q "%%D"
   

3. You need to skip the question for del and remove read-only files too:

   del /f /q *
   

so you arrive at:

@echo off
cd /D %temp%
for /d %%D in (*) do rd /s /q "%%D"
del /f /q *

I was having this exact same problem but mine wasn't because I was setting a local variable... I was in a child window, and I needed to set a relative DataContext which I just added to the Window XAML.

<Window x:Class="Log4Net_Viewer.LogItemWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    DataContext="{Binding RelativeSource={RelativeSource Self}}"
    Title="LogItemWindow" Height="397" Width="572">

You should use urllib2, like this:

import urllib2
for url in ["http://entrian.com/", "http://entrian.com/does-not-exist/"]:
    try:
        connection = urllib2.urlopen(url)
        print connection.getcode()
        connection.close()
    except urllib2.HTTPError, e:
        print e.getcode()

# Prints:
# 200 [from the try block]
# 404 [from the except block]

"Only conventions? Or is there more behind the underscore prefix?"

Apart from privacy conventions, I also wanted to help bring awareness that the underscore prefix is also used for arguments that are dependent on independent arguments, specifically in URI anchor maps. Dependent keys always point to a map.

Example ( from https://github.com/mmikowski/urianchor ) :

$.uriAnchor.setAnchor({
  page   : 'profile',
  _page  : {
    uname   : 'wendy',
    online  : 'today'
  }
});

The URI anchor on the browser search field is changed to:

\#!page=profile:uname,wendy|online,today

This is a convention used to drive an application state based on hash changes.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

NOTE: The make tool reads the makefile and checks the modification time-stamps of the files at both the side of ':' symbol in a rule.

Example

In a directory 'test' following files are present:

prerit@vvdn105:~/test$ ls
hello  hello.c  makefile

In makefile a rule is defined as follows:

hello:hello.c
    cc hello.c -o hello

Now assume that file 'hello' is a text file containing some data, which was created after 'hello.c' file. So the modification (or creation) time-stamp of 'hello' will be newer than that of the 'hello.c'. So when we will invoke 'make hello' from command line, it will print as:

make: `hello' is up to date.

Now access the 'hello.c' file and put some white spaces in it, which doesn't affect the code syntax or logic then save and quit. Now the modification time-stamp of hello.c is newer than that of the 'hello'. Now if you invoke 'make hello', it will execute the commands as:

cc hello.c -o hello

And the file 'hello' (text file) will be overwritten with a new binary file 'hello' (result of above compilation command).

If we use .PHONY in makefile as follow:

.PHONY:hello

hello:hello.c
    cc hello.c -o hello

and then invoke 'make hello', it will ignore any file present in the pwd 'test' and execute the command every time.

Now suppose, that 'hello' target has no dependencies declared:

hello:
    cc hello.c -o hello

and 'hello' file is already present in the pwd 'test', then 'make hello' will always show as:

make: `hello' is up to date.

Calendar.getInstance().get(Calendar.MONTH);

is zero based, 10 is November. From the javadoc;

public static final int MONTH Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

Calendar.getInstance().get(Calendar.JANUARY);

is not a sensible thing to do, the value for JANUARY is 0, which is the same as ERA, you are effectively calling;

Calendar.getInstance().get(Calendar.ERA);

To insert into a very long string it is nice to use names for the different arguments, instead of hoping they are in the right positions. This also makes it easier to replace multiple recurrences.

>>> 'Coordinates: {latitude}, {longitude}'.format(latitude='37.24N', longitude='-115.81W')
'Coordinates: 37.24N, -115.81W'

Taken from Format examples, where all the other Format-related answers are also shown.

You can use GNU awk:

$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]

$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta
http://www.mysite.net/

If there are any proxy networks are configured remove them till plugins are installed

Actually, you only need to use the default argument to add_argument as in this test.py script:

import argparse

if __name__ == '__main__':

    parser = argparse.ArgumentParser()
    parser.add_argument('--example', default=1)
    args = parser.parse_args()
    print(args.example)

test.py --example
% 1
test.py --example 2
% 2

Details are here.

I'd suggest, to add in the nugget package:

  Install-Package OpenDialog

Then the way to used it is:

    Gat.Controls.OpenDialogView openDialog = new Gat.Controls.OpenDialogView();
    Gat.Controls.OpenDialogViewModel vm = (Gat.Controls.OpenDialogViewModel)openDialog.DataContext;
    vm.IsDirectoryChooser = true;
    vm.Show();

    WPFLabel.Text = vm.SelectedFilePath.ToString();

Here's the documentation: http://opendialog.codeplex.com/documentation

Works for Files, files with filter, folders, etc

jQuery has the following signature for the .on() method: .on( events [, selector ] [, data ], handler )

Events could be anyone of the ones listed on this reference:

https://developer.mozilla.org/en-US/docs/Web/Events

Though, they are not all supported by every browser.

Mozilla states the following about the input event:

The DOM input event is fired synchronously when the value of an or element is changed. Additionally, it fires on contenteditable editors when its contents are changed.

Just a precision to Ellis Whitehead's answer. $locationProvider.html5Mode(true); won't work with new version of angularjs without specifying the base URL for the application with a <base href=""> tag or setting the parameter requireBase to false

From the doc :

If you configure $location to use html5Mode (history.pushState), you need to specify the base URL for the application with a tag or configure $locationProvider to not require a base tag by passing a definition object with requireBase:false to $locationProvider.html5Mode():

$locationProvider.html5Mode({
  enabled: true,
  requireBase: false
});

Bringing my answer from another question.

From the C specification, section 6.7.2:

— unsigned, or unsigned int

Meaning that unsigned, when not specified the type, shall default to unsigned int. So writing unsigned a is the same as unsigned int a.

<%: Html.RadioButtonFor(m => m.Gender, "Male", new { @checked = true } )%>

or

@checked = checked

Others have provided answers for how to change the title size, but as for the axes tick label size, you can also use the set_tick_params method.

E.g., to make the x-axis tick label size small:

ax.xaxis.set_tick_params(labelsize='small')

or, to make the y-axis tick label large:

ax.yaxis.set_tick_params(labelsize='large')

You can also enter the labelsize as a float, or any of the following string options: 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', or 'xx-large'.

You do not set such attributes in strings.xml type of files. You need to set it in your code. or (which is better solution) create style with colors you want and apply to your TextView

Getting cuDNN Version [Linux]

Use following to find path for cuDNN:

cat $(whereis cudnn.h) | grep CUDNN_MAJOR -A 2

If above doesn't work try this:

cat $(whereis cuda)/include/cudnn.h | grep CUDNN_MAJOR -A 2

Getting cuDNN Version [Windows]

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN6\cuda\bin\cudnn64_6.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN6\cuda\include\cudnn.h" | findstr "CUDNN_MAJOR CUDNN_MINOR CUDNN_PATCHLEVEL"

Getting CUDA Version

This works on Linux as well as Windows:

I encountered this issue today. the issue has to do with the $config['base_url'] . I noticed htpp://www.domain.com and http://example.com was the issue. to fix , always set your base_url to http://www.example.com

Like most of the other answers have said, instance methods use an instance of a class, whereas a class method can be used with just the class name. In Objective-C they are defined thusly:

@interface MyClass : NSObject

+ (void)aClassMethod;
- (void)anInstanceMethod;

@end

They could then be used like so:

[MyClass aClassMethod];

MyClass *object = [[MyClass alloc] init];
[object anInstanceMethod];

Some real world examples of class methods are the convenience methods on many Foundation classes like NSString's +stringWithFormat: or NSArray's +arrayWithArray:. An instance method would be NSArray's -count method.

You have to use the FormulaEvaluator, as shown here. This will return a value that is either the value present in the cell or the result of the formula if the cell contains such a formula :

FileInputStream fis = new FileInputStream("/somepath/test.xls");
Workbook wb = new HSSFWorkbook(fis); //or new XSSFWorkbook("/somepath/test.xls")
Sheet sheet = wb.getSheetAt(0);
FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

// suppose your formula is in B3
CellReference cellReference = new CellReference("B3"); 
Row row = sheet.getRow(cellReference.getRow());
Cell cell = row.getCell(cellReference.getCol()); 

if (cell!=null) {
    switch (evaluator.evaluateFormulaCell(cell)) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cell.getBooleanCellValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cell.getNumericCellValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cell.getStringCellValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            System.out.println(cell.getErrorCellValue());
            break;

        // CELL_TYPE_FORMULA will never occur
        case Cell.CELL_TYPE_FORMULA: 
            break;
    }
}

if you need the exact contant (ie the formla if the cell contains a formula), then this is shown here.

Edit : Added a few example to help you.

first you get the cell (just an example)

Row row = sheet.getRow(rowIndex+2);    
Cell cell = row.getCell(1);   

If you just want to set the value into the cell using the formula (without knowing the result) :

 String formula ="ABS((1-E"+(rowIndex + 2)+"/D"+(rowIndex + 2)+")*100)";    
 cell.setCellFormula(formula);    
 cell.setCellStyle(this.valueRightAlignStyleLightBlueBackground);

if you want to change the message if there is an error in the cell, you have to change the formula to do so, something like

IF(ISERR(ABS((1-E3/D3)*100));"N/A"; ABS((1-E3/D3)*100))

(this formula check if the evaluation return an error and then display the string "N/A", or the evaluation if this is not an error).

if you want to get the value corresponding to the formula, then you have to use the evaluator.

Hope this help,
Guillaume

Feedback Guys, first create database example live; before execute sql file below.

Check out this one:

It's a high level library for dealing with REST. It's OOP, works with JSON, but also works with any other format.

There are two ways you can do this; with patch and with patch.object

Patch assumes that you are not directly importing the object but that it is being used by the object you are testing as in the following

#foo.py
def some_fn():
    return 'some_fn'

class Foo(object):
    def method_1(self):
        return some_fn()

#bar.py
import foo
class Bar(object):
    def method_2(self):
        tmp = foo.Foo()
        return tmp.method_1()

#test_case_1.py
import bar
from mock import patch

@patch('foo.some_fn')
def test_bar(mock_some_fn):
    mock_some_fn.return_value = 'test-val-1'
    tmp = bar.Bar()
    assert tmp.method_2() == 'test-val-1'
    mock_some_fn.return_value = 'test-val-2'
    assert tmp.method_2() == 'test-val-2'

If you are directly importing the module to be tested, you can use patch.object as follows:

#test_case_2.py
import foo
from mock import patch

@patch.object(foo, 'some_fn')
def test_foo(test_some_fn):
    test_some_fn.return_value = 'test-val-1'
    tmp = foo.Foo()
    assert tmp.method_1() == 'test-val-1'
    test_some_fn.return_value = 'test-val-2'
    assert tmp.method_1() == 'test-val-2'

In both cases some_fn will be 'un-mocked' after the test function is complete.

Edit: In order to mock multiple functions, just add more decorators to the function and add arguments to take in the extra parameters

@patch.object(foo, 'some_fn')
@patch.object(foo, 'other_fn')
def test_foo(test_other_fn, test_some_fn):
    ...

Note that the closer the decorator is to the function definition, the earlier it is in the parameter list.

They're not actually characters, they're hexadecimal digits.

if it's not a foreign key field, not using empty strings could save you some trouble. only allow nulls if you'll take null to mean something different than an empty string. for example if you have a password field, a null value could indicate that a new user has not created his password yet while an empty varchar could indicate a blank password. for a field like "address2" allowing nulls can only make life difficult. things to watch out for include null references and unexpected results of = and <> operators mentioned by Vagif Verdi, and watching out for these things is often unnecessary programmer overhead.

edit: if performance is an issue see this related question: Nullable vs. non-null varchar data types - which is faster for queries?

I would use:

awk 'FNR <= 1' file_*.txt

As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1 may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i' to 'FNR <= i' allows to obtain the first i lines.

For example, if you have n files named file_1.txt, ... file_n.txt:

awk 'FNR <= 1' file_*.txt

hello
...
bye

But with head wildcards print the name of the file:

head -1 file_*.txt

==> file_1.csv <==
hello
...
==> file_n.csv <==
bye

This type of data is efficiently pulled from a Trie-like data structure. It also allows for fast sorting. The memory efficiency might not be that great though.

A traditional trie stores each letter of a word as a node in the tree. But in your case your "alphabet" is different. You are storing strings instead of characters.

it might look something like this:

root:                Root
                     /|\
                    / | \
                   /  |  \     
fruit:       Banana Apple Strawberry
              / |      |     \
             /  |      |      \
color:     Blue Yellow Green  Blue
            /   |       |       \
           /    |       |        \
end:      24   100      12        0

Remove-Item -Recurse -Force some_dir

does indeed work as advertised here.

rm -r -fo some_dir

are shorthand aliases that work too.

As far as I understood it, the -Recurse parameter just doesn't work correctly when you try deleting a filtered set of files recursively. For killing a single dir and everything below it seems to work fine.

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

A simple way to achieve this is by using np.convolve. The idea behind this is to leverage the way the discrete convolution is computed and use it to return a rolling mean. This can be done by convolving with a sequence of np.ones of a length equal to the sliding window length we want.

In order to do so we could define the following function:

def moving_average(x, w):
    return np.convolve(x, np.ones(w), 'valid') / w

This function will be taking the convolution of the sequence x and a sequence of ones of length w. Note that the chosen mode is valid so that the convolution product is only given for points where the sequences overlap completely.

Some examples:

x = np.array([5,3,8,10,2,1,5,1,0,2])

For a moving average with a window of length 2 we would have:

moving_average(x, 2)
# array([4. , 5.5, 9. , 6. , 1.5, 3. , 3. , 0.5, 1. ])

And for a window of length 4:

moving_average(x, 4)
# array([6.5 , 5.75, 5.25, 4.5 , 2.25, 1.75, 2.  ])

How does convolve work?

Lets have a more in depth look at the way the discrete convolution is being computed. The following function aims to replicate the way np.convolve is computing the output values:

def mov_avg(x, w):
    for m in range(len(x)-(w-1)):
        yield sum(np.ones(w) * x[m:m+w]) / w 

Which, for the same example above would also yield:

list(mov_avg(x, 2))
# [4.0, 5.5, 9.0, 6.0, 1.5, 3.0, 3.0, 0.5, 1.0]

So what is being done at each step is to take the inner product between the array of ones and the current window. In this case the multiplication by np.ones(w) is superfluous given that we are directly taking the sum of the sequence.

Bellow is an example of how the first outputs are computed so that it is a little clearer. Lets suppose we want a window of w=4:

[1,1,1,1]
[5,3,8,10,2,1,5,1,0,2]
= (1*5 + 1*3 + 1*8 + 1*10) / w = 6.5

And the following output would be computed as:

  [1,1,1,1]
[5,3,8,10,2,1,5,1,0,2]
= (1*3 + 1*8 + 1*10 + 1*2) / w = 5.75

And so on, returning a moving average of the sequence once all overlaps have been performed.

For PHPUnit 5.7.27 and PHP 5.6 and to test multiple exceptions in one test, it was important to force the exception testing. Using exception handling alone to assert the instance of Exception will skip testing the situation if no exception occurs.

public function testSomeFunction() {

    $e=null;
    $targetClassObj= new TargetClass();
    try {
        $targetClassObj->doSomething();
    } catch ( \Exception $e ) {
    }
    $this->assertInstanceOf(\Exception::class,$e);
    $this->assertEquals('Some message',$e->getMessage());

    $e=null;
    try {
        $targetClassObj->doSomethingElse();
    } catch ( Exception $e ) {
    }
    $this->assertInstanceOf(\Exception::class,$e);
    $this->assertEquals('Another message',$e->getMessage());

}

In my case it was an incompatible Project Type. Editing project file and removing ProjectTypeGuids node resolved the issue of loading the project (I had already re-targeted the framework version as advised here).

Probably the project type is not supported in the (most likely) NEW version of VS, so you will have to adjust (update) the code to work properly (if possible), but at least you can see the content through VS.

Use Microsoft Sysinternals Sigcheck. This sample outputs just the version:

sigcheck -q -n foo.dll

Unpacked sigcheck.exe is only 228 KB.

mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).

You type that command from a shell prompt.

Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:

FLUSH HOSTS;

http://dev.mysql.com/doc/refman/5.6/en/flush.html

http://dev.mysql.com/doc/refman/5.6/en/mysqladmin.html

In my case, this error occurred, due to lack of existence of column name in the table.

When i executed "describe tablename" , i was not able to find the column specified in the mapping hbm file.

After altering the table, it worked fine.

I believe this is what you're looking for:

char[] characters = "this is a test".ToCharArray();

You can delete either whole index,doc-type or a perticular id data. these are the three ways:

1. curl -XDELETE localhost:9200/index_name

2. curl -XDELETE localhost:9200/index_name/doc-type

3. curl -XDELETE localhost:9200/index_name/doc-type/documentId

and if you wish to delete all the index then go for wildcard.

To install GLIBC_2.14 or GLIBC_2.15, download package from /gnu/libc/ index at

https://ftp.gnu.org/gnu/libc/

Then follow instructions listed by Timo:

For example glibc-2.14.tar.gz in your case.

1. tar xvfz glibc-2.14.tar.gz

2. cd glibc-2.14

3. mkdir build

4. cd build

5. ../configure --prefix=/opt/glibc-2.14

6. make

7. sudo make install

8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

I wrote this script to skip or execute tests if there are changes:

#!/bin/bash

set -e -o pipefail -u

paths=()
while [ "$1" != "--" ]; do
    paths+=( "$1" ); shift
done
shift

if git diff --quiet --exit-code "${BASE_BRANCH:-origin/master}"..HEAD ${paths[@]}; then
    echo "No changes in ${paths[@]}, skipping $@..." 1>&2
    exit 0
fi
echo "Changes found in ${paths[@]}, running $@..." 1>&2

exec "$@"

So you can do something like:

./scripts/git-run-if-changed.sh cmd vendor go.mod go.sum fixtures/ tools/ -- go test

I would use SQL Server Full Text Indexing, which will allow you to do searches and return things that not only contain the word but also may have a misspelling.

If your widget is a Button:

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:weightSum="2"
    android:orientation="horizontal">
    <Button android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="somebutton"/>

    <TextView android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"/>
</LinearLayout>

I'm assuming you want your widget to take up one half, and another widget to take up the other half. The trick is using a LinearLayout, setting layout_width="fill_parent" on both widgets, and setting layout_weight to the same value on both widgets as well. If there are two widgets, both with the same weight, the LinearLayout will split the width between the two widgets.

I noticed that problem because of AdBlock Extension, I turned off AdBlock extension the issue got resolve.

The problem is with sprintf

sprintf(aa,"%lf",a);

%lf says to interpet "a" as a "long double" (16 bytes) but it is actually a "double" (8 bytes). Use this instead:

sprintf(aa, "%f", a);

Manually deleting it in the chrome browser removes the cookie from Postman.

Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).

It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).

But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.

A good example: here

And a good documentation from Mozilla: here

if discount.nil? || discount == 0

Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach that is not an array.

Look at what you're passing into foreach, determine what it is (with var_export), find out why it's not an array... and fix it.

Basic, basic debugging.

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

Is that what you need?

I don't see how that format is necessarily easy to work with in SQL queries, though.

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>
elseif (e instanceof HTMLSelectElement) {}    // <select>
elseif (e instanceof HTMLTextAreaElement) {}  // <textarea>
elseif (  ... ) {}                            // any interface

Look here for a complete list of interfaces.

What I can do to fix this (other than installing a real SSL certificate).

You can't.

On an https webpage you can only make AJAX request to https webpage (With a certificate trusted by the browser, if you use a self-signed one, it will not work for your visitors)

From the documentation:

Paths associated with the default provider are generally interoperable with the java.io.File class. Paths created by other providers are unlikely to be interoperable with the abstract path names represented by java.io.File. The toPath method may be used to obtain a Path from the abstract path name represented by a java.io.File object. The resulting Path can be used to operate on the same file as the java.io.File object. In addition, the toFile method is useful to construct a File from the String representation of a Path.

(emphasis mine)

So, for toFile:

Returns a File object representing this path.

And toPath:

Returns a java.nio.file.Path object constructed from the this abstract path.

In my case, This problem was caused by a mismatch in my Target framework setting under each project. When I created a new project, VS 2015 defaulted to 4.5.2, however all my nuget packages were built for 4.6.

For some reason, VS 2015 was not showing me these errors. I didn't see them until I created a new empty project and tried to add my nuget project there. This behavior may have been aggravated because I had renamed the project a few times during the initial setup.

I solved the problem by

• changing the Target Framework on my projects to 4.6
• closed VS 2015
• deleted "packages", "obj" and "bin" folders
• re-open the solution and try to add the nuget package again.

The code you pasted should work... There must be something else we are not seeing here.

Check this out. Working for me fine on IE7. When you submit you will see the variable passed in the URL.

You can also drag a tap gesture recogniser to the image view in Storyboard. Then create an action by ctrl + drag to the code.

It works by same principle of anonymous inner class where we can instantiate an interface without actually defining a class :

Ref: https://www.geeksforgeeks.org/anonymous-inner-class-java/

Found another (manual) answer which worked well for me

1. Select the column.
2. Choose Data tab
3. Text to Columns - opens new box
4. (choose Delimited), Next
5. (uncheck all boxes, use "none" for text qualifier), Next
6. use the ymd option from the Date dropdown.
7. Click Finish

Absolutely.

If the constructor doesn't receive valid input, or can't construct the object in a valid manner, it has no other option but to throw an exception and alert its caller.

A programmatic solution:

SELECT pg_encoding_to_char(encoding) FROM pg_database WHERE datname = 'yourdb';

The easiest way is to hard code the columns yourself to better control the output file:

SELECT 'ColName1', 'ColName2', 'ColName3'
UNION ALL
SELECT ColName1, ColName2, ColName3
    FROM YourTable
    INTO OUTFILE '/path/outfile'

Update 3:
This warning can also be triggered by labels that have numberOfLines set to anything but 1 if your deployment target is set to 7.1. This is completely reproducible with new single-view project.

Steps to Reproduce:

1. Create a new single-view, objective-c project
2. Set the Deployment Target to 7.1
3. Open the project's storyboard
4. Drop a label onto the provided view controller
5. Set the numberOfLines for that label to 2.
6. Compile

I've filed the following radar:
rdar://problem/18700567

Update 2:
Unfortunately, this is a thing again in the release version of Xcode 6. Note that you can, for the most part, manually edit your storyboard/xib to fix the problem. Per Charles A. in the comments below:

It's worth mentioning that you can pretty easily accidentally introduce this warning, and the warning itself doesn't help in finding the label that is the culprit. This is unfortunate in a complex storyboard. You can open the storyboard as a source file and search with the regex <label(?!.*preferredMaxLayoutWidth) to find labels that omit a preferredMaxLayoutWidth attribute/value. If you add in preferredMaxLayoutWidth="0" on such lines, it is the same as marking explicit and setting the value 0.

Update 1:
This bug has now been fixed in Xcode 6 GM.

Original Answer
This is a bug in Xcode6-Beta6 and XCode6-Beta7 and can be safely ignored for now.

An Apple engineer in the Apple Developer forums had this to say about the bug:

Preferred max layout width is an auto layout property on UILabel that allows it to automatically grow vertically to fit its content. Versions of Xcode prior to 6.0 would set preferredMaxLayoutWidth for multiline labels to the current bounds size at design time. You would need to manually update preferredMaxLayoutWidth at runtime if your horizontal layout changed.

iOS 8 added support for automatically computing preferredMaxLayoutWidth at runtime, which makes creating multiline labels even easier. This setting is not backwards compatible with iOS 7. To support both iOS 7 and iOS 8, Xcode 6 allows you to pick either "Automatic" or "Explicit" for preferredMaxLayoutWidth in the size inspector. You should:

Pick "Automatic" if targeting iOS 8 for the best experience. Pick "Explicit" if targeting < iOS 8. You can then enter the value of preferredMaxLayoutWidth you would like set. Enabling "Explicit" defaults to the current bounds size at the time you checked the box.

The warning will appear if (1) you're using auto layout, (2) "Automatic" is set for a multiline label [you can check this in the size inspector for the label], and (3) your deployment target < iOS 8.

It seems the bug is that this warning appears for non-autolayout documents. If you are seeing this warning and not using auto layout you can ignore the warning.

Alternately, you can work around the issue by using the file inspector on the storyboard or xib in question and change "Builds for" to "Builds for iOS 8.0 and Later"

Change your network adapter to a bridged connection, this will directly connect to your computers physical network.

might need change to right owner to operate it.

I have employed a slightly different technique in my aspnet MVC 4 site:

_ViewStart.cshtml:

@using System.Web.Caching
@using System.Web.Hosting
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
    PageData.Add("scriptFormat", string.Format("<script src=\"{{0}}?_={0}\"></script>", GetDeployTicks()));
}

@functions
{

    private static string GetDeployTicks()
    {
        const string cacheKey = "DeployTicks";
        var returnValue = HttpRuntime.Cache[cacheKey] as string;
        if (null == returnValue)
        {
            var absolute = HostingEnvironment.MapPath("~/Web.config");
            returnValue = File.GetLastWriteTime(absolute).Ticks.ToString();
            HttpRuntime.Cache.Insert(cacheKey, returnValue, new CacheDependency(absolute));
        }
        return returnValue;
    }
}

Then in the actual views:

 @Scripts.RenderFormat(PageData["scriptFormat"], "~/Scripts/Search/javascriptFile.min.js")

A functional requirement describes what a software system should do, while non-functional requirements place constraints on how the system will do so.

Let me elaborate.

An example of a functional requirement would be:

• A system must send an email whenever a certain condition is met (e.g. an order is placed, a customer signs up, etc).

A related non-functional requirement for the system may be:

• Emails should be sent with a latency of no greater than 12 hours from such an activity.

The functional requirement is describing the behavior of the system as it relates to the system's functionality. The non-functional requirement elaborates a performance characteristic of the system.

Typically non-functional requirements fall into areas such as:

• Accessibility
• Capacity, current and forecast
• Compliance
• Documentation
• Disaster recovery
• Efficiency
• Effectiveness
• Extensibility
• Fault tolerance
• Interoperability
• Maintainability
• Privacy
• Portability
• Quality
• Reliability
• Resilience
• Response time
• Robustness
• Scalability
• Security
• Stability
• Supportability
• Testability

A more complete list is available at Wikipedia's entry for non-functional requirements.

Non-functional requirements are sometimes defined in terms of metrics (i.e. something that can be measured about the system) to make them more tangible. Non-functional requirements may also describe aspects of the system that don't relate to its execution, but rather to its evolution over time (e.g. maintainability, extensibility, documentation, etc.).

Static array :Efficiency. No dynamic allocation or deallocation is required.

Arrays declared in C, C++ in function including static modifier are static. Example: static int foo[5];

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

I just had the same issue with Netbeans 8.2 and trying to connect to mySQL server on a Mac OS machine. The only thing that worked for me was to add the following to the url of the connection string: &serverTimezone=UTC (or if you are connecting via Hibernate.cfg.xml then escape the & as &) Not surprisingly I found the solution on this stack overflow post also:

Uninstall composer

To remove just composer package itself from Ubuntu 16.04 (Xenial Xerus) execute on terminal:

sudo apt-get remove composer

Uninstall composer and it's dependent packages

To remove the composer package and any other dependant package which are no longer needed from Ubuntu Xenial.

sudo apt-get remove --auto-remove composer

Purging composer

If you also want to delete configuration and/or data files of composer from Ubuntu Xenial then this will work:

sudo apt-get purge composer

To delete configuration and/or data files of composer and it's dependencies from Ubuntu Xenial then execute:

sudo apt-get purge --auto-remove composer

I've used them as static variables for a function. For example, given the following C code:

int fn(int i)
{
    static f = 1;
    f += i;
    return f;
}

I can implement the function similarly in Python:

def fn(i):
    fn.f += i
    return fn.f
fn.f = 1

This would definitely fall into the "abuses" end of the spectrum.

Disclaimer: The original question was about MySQL. The SQL Server answer is below.

MySQL

In MySQL, the regex syntax is the following:

SELECT * FROM YourTable WHERE (`url` NOT REGEXP '^[-A-Za-z0-9/.]+$') 

Use the REGEXP clause instead of LIKE. The latter is for pattern matching using % and _ wildcards.

SQL Server

Since you made a typo, and you're using SQL Server (not MySQL), you'll have to create a user-defined CLR function to expose regex functionality.

Take a look at this article for more details.

Use git reflog to list all changes made in your git history. Copy an action id and type git reset ACTION_ID

To ensure that a cell will return a date value and not just a string that looks like a date, first you must set the NumberFormat property to a Date format, then put a real date into the cell's content.

Sub test_date_or_String()
 Set c = ActiveCell
 c.NumberFormat = "@"
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a String
 c.NumberFormat = "m/d/yyyy"
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is still a String
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a date    
End Sub

I got this error when using GroupBy via LINQ on a MySQL database. The problem was that the anonymous object property that was being used by GroupBy did not match the database column name. Fixed by renaming anonymous property name to match the column name.

.Select(f => new 
{
   ThisPropertyNameNeedsToMatchYourColumnName = f.SomeName
})
.GroupBy(t => t.ThisPropertyNameNeedsToMatchYourColumnName);

Yowsup provide best solution with example.you can download api from https://github.com/tgalal/yowsup let me know if you have any issue.

Swipe events are a kind of onTouch events. Simply simplifying @Gal Rom 's answer, just keep track of the vertical an horizontal deltas, and with a little math you can determine what kind of swipe a touchEvent was. (Again, let me stress that this was OBSENELY based to a previous answer, but the simplicity may appeal to novices). The idea is to extend an OnTouchListener, detect what kind of swipe (touch) just happened and call specific methods for each kind.

public class SwipeListener implements View.OnTouchListener {
    private int min_distance = 100;
    private float downX, downY, upX, upY;
    View v;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        this.v = v;
        switch(event.getAction()) { // Check vertical and horizontal touches
            case MotionEvent.ACTION_DOWN: {
                downX = event.getX();
                downY = event.getY();
                return true;
            }
            case MotionEvent.ACTION_UP: {
                upX = event.getX();
                upY = event.getY();

                float deltaX = downX - upX;
                float deltaY = downY - upY;

                //HORIZONTAL SCROLL
                if (Math.abs(deltaX) > Math.abs(deltaY)) {
                    if (Math.abs(deltaX) > min_distance) {
                        // left or right
                        if (deltaX < 0) {
                            this.onLeftToRightSwipe();
                            return true;
                        }
                        if (deltaX > 0) {
                            this.onRightToLeftSwipe();
                            return true;
                        }
                    } else {
                        //not long enough swipe...
                        return false;
                    }
                }
                //VERTICAL SCROLL
                else {
                    if (Math.abs(deltaY) > min_distance) {
                        // top or down
                        if (deltaY < 0) {
                            this.onTopToBottomSwipe();
                            return true;
                        }
                        if (deltaY > 0) {
                            this.onBottomToTopSwipe();
                            return true;
                        }
                    } else {
                        //not long enough swipe...
                        return false;
                    }
                }
                return false;
            }
        }
        return false;
    }

    public void onLeftToRightSwipe(){
        Toast.makeText(v.getContext(),"left to right",   
                                      Toast.LENGTH_SHORT).show();
    }

    public void onRightToLeftSwipe() {
        Toast.makeText(v.getContext(),"right to left",
                                     Toast.LENGTH_SHORT).show();
    }

    public void onTopToBottomSwipe() {
        Toast.makeText(v.getContext(),"top to bottom", 
                                     Toast.LENGTH_SHORT).show();
    }

    public void onBottomToTopSwipe() {
        Toast.makeText(v.getContext(),"bottom to top",

    }
}

The answers already explain how attributes and properties are handled differently, but I really would like to point out how totally insane this is. Even if it is to some extent the spec.

It is crazy, to have some of the attributes (e.g. id, class, foo, bar) to retain only one kind of value in the DOM, while some attributes (e.g. checked, selected) to retain two values; that is, the value "when it was loaded" and the value of the "dynamic state". (Isn't the DOM supposed to be to represent the state of the document to its full extent?)

It is absolutely essential, that two input fields, e.g. a text and a checkbox behave the very same way. If the text input field does not retain a separate "when it was loaded" value and the "current, dynamic" value, why does the checkbox? If the checkbox does have two values for the checked attribute, why does it not have two for its class and id attributes? If you expect to change the value of a text *input* field, and you expect the DOM (i.e. the "serialized representation") to change, and reflect this change, why on earth would you not expect the same from an input field of type checkbox on the checked attribute?

The differentiation, of "it is a boolean attribute" just does not make any sense to me, or is, at least not a sufficient reason for this.

Spring Boot provide the plugin with maven.

So you can go to your project directory and run

mvn spring-boot:run

This command line run will be easily when you're using spring-boot-devs-tool with auto reload/restart when you have changed you application.

Now that most people use Kotlin instead of Java, here is the code in Kotlin for converting a bitmap into a base64 string.

import java.io.ByteArrayOutputStream

private fun encodeImage(bm: Bitmap): String? {
        val baos = ByteArrayOutputStream()
        bm.compress(Bitmap.CompressFormat.JPEG, 100, baos)
        val b = baos.toByteArray()
        return Base64.encodeToString(b, Base64.DEFAULT)
    }

Okay, I am now connecting without the semaphore timeout problem.

If anyone reading ever encounters the same thing, I hope that this procedure works for you; but no promises; hey, it's windows.

In my case this was Windows 7

I got a little hint from This page on eHow; not sure if that might help anyone or not.

So anyway, this was the simple twenty three step procedure that worked for me

• Click on start button

• Choose Control Panel

• From Control Panel, choose Device Manger

• From Device Manager, choose Universal Serial Bus Controllers

• From Universal Serial Bus Controllers, click the little sideways triangle

• I cannot predict what you'll see on your computer, but on mine I get a long drop-down list

• Begin the investigation to figure out which one of these members of this list is the culprit...

  • On each member of the drop-down list, right-click on the name

  • A list will open, choose Properties

  • Guesswork time: using the various tabs near the top of the resulting window which opens, make a guess if this is the USB adapter driver which is choking your stuff with semaphore timeouts

• Once you have made the proper guess, then close the USB Root Hub Properties window (but leave the Device Manager window open).

• Physically disonnect anything and everything from that USB hub.

• Unplug it.

• Return your mouse pointer to that USB Root Hub in the list which you identified earlier.

• Right click again

• Choose Uninstall

• Let Windows do its thing

• Wait a little while

• Power Down the whole computer if you have the time; some say this is required. I think I got away without it.

• Plug the USB hub back into a USB connector on the PC

• If the list in the device manager blinks and does a few flash-bulbs, it's okay.

• Plug the BlueTooth connector back into the USB hub

• Let windows do its thing some more

• Within two minutes, I had a working COM port again, no semaphore timeouts.

Hope it works for anyone else who may be having a similar problem.

You can also do the same thing in another way,

If you are using PHP 5.5 or latest one then you can do it as follow,

Controller:

return view(index, compact('data1','data2')); //as many as you want to pass

View:

<div>
    You can access {{$data1}}. [if it is variable]
</div>

@foreach($data1 as $d1)
    <div>
        You can access {{$d1}}. [if it is array]
    </div>
@endforeach

Same way you can access all variable that you have passed in compact function.

Hope it helps :)

If you are working with php in windows, you can just access to the file "php.ini" located in your php instalation folder and uncomment the ";extension=xmlrpc" line deleting the ";" ("extension=xmlrpc")

Maybe you have to try getActivity().getSupportActionBar().setTitle() if you are using support_v7.

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

The solution is isblank(cell)=false

int a = 4, b = 6;
a ^= b ^= a ^= b;

Works for all types including strings and floats.

You find source (Scala) here and an working applet here.

Since 0 and 1 aren't matched to characters, they build natural breakpoints in numbers. But they don't occur in every number (except 0 at the beginning). Longer numbers like +49567892345 from 9 digits starting, can lead to OutOfMemoryErrors. So it would be better to split a number into groups like

• 01723 5864
• 0172 35864

to see, if you can make sense from the shorter parts. I wrote such a program, and tested some numbers from my friends, but found rarely combinations of shorter words, which could be checked in a dictionary for matching, not to mention single, long words.

So my decision was to only support searching, no full automation, by displaying possible combinations, encouraging splitting the number by hand, maybe multiple time.

So I found +-RAD JUNG (+-bycicle boy).

If you accept misspellings, abbreviations, foreign words, numbers as words, numbers in words, and names, your chance to find a solution is much better, than without fiddling around.

246848 => 2hot4u (too hot for you) 
466368 => goodn8 (good night) 
1325   => 1FCK   (Football club)
53517  => JDK17  (Java Developer Kit)

are things a human might observe - to make an algorithm find such things is rather hard.

For those of you running into the ever so common error "fatal: remote origin already exists.", or when trying to remove origin and you get "error: could not remove config section remote.origin", what you need to do is to set the origin manually.

Window's POSH~Git for Windows PowerShell (and GitHub for Windows' app) has a problem with this.

I ran into this, like I do so often, again when setting up my octopress. So, here's how I got it working.

First, check your remotes:

C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress       https://github.com/imathis/octopress.git (fetch)
octopress       https://github.com/imathis/octopress.git (push)
origin

You'll first note that my origin has no url. Any attempt to remove it, rename it, etc all fails.

So, change the url manually:

git remote set-url --add origin https://github.com/eduncan911/eduncan911.github.io.git

Then you can confirm it worked by running git remote -v again:

C:\gd\code\octopress [source +2 ~3 -0 !]> git remote -v
octopress       https://github.com/imathis/octopress.git (fetch)
octopress       https://github.com/imathis/octopress.git (push)
origin  https://github.com/eduncan911/eduncan911.github.io.git (fetch)
origin  https://github.com/eduncan911/eduncan911.github.io.git (push)

This has fixed dozens of git repos I've had issues with, GitHub, BitBucket GitLab, etc.

I was getting this error. Turns out I had just upgraded OSX to Sierra and my old key was no longer registered.

At first I thought it was "Upgrading to macOS Sierra will break your SSH keys and lock you out of your own servers"

But I had sidestepped that one. Turns out I just had to re-register my existing key:

ssh-add -K

And type the passphrase... done!

This is a late answer, but by looking at the source code, I noticed that when the video is fullscreen, the "mejs-container-fullscreen" class is added to the "mejs-container" element. It is thus possible to change the styling based on this class.

.mejs-container.mejs-container-fullscreen {
    // This rule applies only to the container when in fullscreen
    padding-top: 57%;
}

Also, if you wish to make your MediaElement video fluid using CSS, below is a great trick by Chris Coyier: http://css-tricks.com/rundown-of-handling-flexible-media/

Just add this to your CSS:

.mejs-container {
    width: 100% !important;
    height: auto !important;
    padding-top: 57%;
}
.mejs-overlay, .mejs-poster {
    width: 100% !important;
    height: 100% !important;
}
.mejs-mediaelement video {
    position: absolute;
    top: 0; left: 0; right: 0; bottom: 0;
    width: 100% !important;
    height: 100% !important;
}

I hope it helps.

You can add a class to the button and put some script redirecting it.

I do it this way:

<button class='buttonClass'>button name</button>

<script>
$(".buttonClass').click(function(){
window.location.href = "http://stackoverflow.com";
});
</script>

Answer suggested by @Stacy Simpson:

We are struggling with the issue described in these threads and none of the resolutions seem to work:

• Stop "developer tools access needs to take control of another process for debugging to continue" alert
• Authorize a non-admin developer in Xcode / Mac OS

As I'm new to SO, I cannot post in either thread. (The first one is actually closed and I disagree with the localization reasoning...)

Anyway, we created a work-around using AppleScript that folks may be interested in. The script below should be executed asynchronously prior to launching your automated test:

osascript <script name> <password> &

Here is the script:

on run argv
    # Delay for 10 seconds as this script runs asynchronously to the automation process and is kicked off first.
    delay 10

    # Inspect all running processes
    tell application "System Events"
        set ProcessList to name of every process
        # Determine if authentication is being requested
        if "SecurityAgent" is in ProcessList then
            # Bring this dialogue to the front
            tell application "SecurityAgent" to activate
            # Enter provided password
            keystroke item 1 of argv
            keystroke return
        end if
    end tell
end run

Probably not very secure, but it's the best work-around we've come up with to allow tests to run without requiring user intervention.

Hopefully, I can get enough points to post the answer; or, someone can unprotect this question. Regards.

Ubuntu 18.04

This worked for me:

1. Find out and copy platform-tools path, in my case is '/home/daniel/Android/Sdk/platform-tools'
2. Open bashrc nano ~/.bashrc
3. Save platform-tools path export PATH="${PATH}:/home/daniel/Android/Sdk/platform-tools"
4. Reset bash_profile source .bash_profile
5. adb devices is now working

Run vmware as administrator in windows or as root in linux. Then ctrl+P to open preferences. then on shared vms. You can see a port number 443 by default. This is conflicting with apache that is why it is not starting. Change it to some other value say 8443. Then try to start apache it will run.

Notice you're not dynamically allocating the variable, which pretty much means the data inside str, in your function, will be lost by the end of the function.

You should have:

char * createStr() {

    char char1= 'm';
    char char2= 'y';

    char *str = malloc(3);
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';

    return str;

}

Then, when you call the function, the type of the variable that will receive the data must match that of the function return. So, you should have:

char *returned_str = createStr();

It worths mentioning that the returned value must be freed to prevent memory leaks.

char *returned_str = createStr();

//doSomething
...

free(returned_str);

I would rather use plt.clf() after every plt.show() to just clear the current figure instead of closing and reopening it, keeping the window size and giving you a better performance and much better memory usage.

Similarly, you could do plt.cla() to just clear the current axes.

To clear a specific axes, useful when you have multiple axes within one figure, you could do for example:

fig, axes = plt.subplots(nrows=2, ncols=2)

axes[0, 1].clear()

Really annoying thing in PS 5, where $_ won't be the full path within foreach. These are the string versions of FileInfo and DirectoryInfo objects. For some reason a wildcard in the path fixes it, or use Powershell 6 or 7. You can also pipe to get-item in the middle.

Get-ChildItem -path C:\WINDOWS\System32\*.txt -Recurse | foreach { "$_" }

Get-ChildItem -path C:\WINDOWS\System32 -Recurse | get-item | foreach { "$_" }

This seems to have been an issue with .Net that got resolved in .Net Core (Powershell 7): Stringification behavior of FileInfo / Directory instances has changed since v6.0.2 #7132

Those reference pretty much answered your question. Simply put, vectors' lengths are dynamic while arrays have a fixed size. when using an array, you specify its size upon declaration:

int myArray[100];
myArray[0]=1;
myArray[1]=2;
myArray[2]=3;

for vectors, you just declare it and add elements

vector<int> myVector;
myVector.push_back(1);
myVector.push_back(2);
myVector.push_back(3);
...

at times you wont know the number of elements needed so a vector would be ideal for such a situation.

Here is the script in Python.

You cannot click on elements in selenium that are hidden. However, you can execute JavaScript to click on the hidden element for you.

element = driver.find_element_by_id(buttonID)
driver.execute_script("$(arguments[0]).click();", element)

I'm using laravel 7.x and this problem arose.. the following fixed it:

go to kernel.php and add these 2 classes to protected $middleware

\Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class,

If there is a hierarchy of exceptions you can use the base class to catch all subclasses of exceptions. In the degenerate case you can catch all Java exceptions with:

try {
   ...
} catch (Exception e) {
   someCode();
}

In a more common case if RepositoryException is the the base class and PathNotFoundException is a derived class then:

try {
   ...
} catch (RepositoryException re) {
   someCode();
} catch (Exception e) {
   someCode();
}

The above code will catch RepositoryException and PathNotFoundException for one kind of exception handling and all other exceptions are lumped together. Since Java 7, as per @OscarRyz's answer above:

try { 
  ...
} catch( IOException | SQLException ex ) {

I see this issue come up a lot. Yes, Tomcat 7 does automatically deregister it, but it that REALLY taking control of your code and a good coding practice? Surely YOU want to know that you have all the correct code in place to close all your objects, shut down database connection pool threads, and get rid of all warnings. I certainly do.

This is how I do it.

Step 1: Register a Listener

web.xml

<listener>
    <listener-class>com.mysite.MySpecialListener</listener-class>
</listener>

Step 2: Implement the Listener

com.mysite.MySpecialListener.java

public class MySpecialListener implements ServletContextListener {

    @Override
    public void contextInitialized(ServletContextEvent sce) {
        // On Application Startup, please…

        // Usually I'll make a singleton in here, set up my pool, etc.
    }

    @Override
    public void contextDestroyed(ServletContextEvent sce) {
        // On Application Shutdown, please…

        // 1. Go fetch that DataSource
        Context initContext = new InitialContext();
        Context envContext  = (Context)initContext.lookup("java:/comp/env");
        DataSource datasource = (DataSource)envContext.lookup("jdbc/database");

        // 2. Deregister Driver
        try {
            java.sql.Driver mySqlDriver = DriverManager.getDriver("jdbc:mysql://localhost:3306/");
            DriverManager.deregisterDriver(mySqlDriver);
        } catch (SQLException ex) {
            logger.info("Could not deregister driver:".concat(ex.getMessage()));
        } 

        // 3. For added safety, remove the reference to dataSource for GC to enjoy.
        dataSource = null;
    }

}

As Jon Skeet mentioned you can do it with a List<Track> instead. The Track class would look something like this:

public class Track {
    public int TrackID { get; set; }
    public string Name { get; set; }
    public string Artist { get; set; }
    public string Album { get; set; }
    public int PlayCount { get; set; }
    public int SkipCount { get; set; }
}

And to create a track list as a List<Track> you simply do this:

var trackList = new List<Track>();

Adding tracks can be as simple as this:

trackList.add( new Track {
    TrackID = 1234,
    Name = "I'm Gonna Be (500 Miles)",
    Artist = "The Proclaimers",
    Album = "Finest",
    PlayCount = 10,
    SkipCount = 1
});

Accessing tracks can be done with the indexing operator:

Track firstTrack = trackList[0];

Hope this helps.

I like ExportHTML, which exports to html, opens it up in your browser, and optionally opens the system print dialog. Looks good, too. Not a perfect replacement for native printing, but pretty close.

In Android Studios 2.1.1, the command-line Options is under "Build, Execution, Deployment">"Compiler"

Really this is an extension to Marcin's answer.

But you could also try passing "rubbish" arguments to see if you get any errors back. Getting any response from the executable directly in the shell will mean that it is likely looking at the arguments you're passing, with an error response being close to a guarantee that it is.

Failing that you might have to directly ask the publishers/creators/owners... sniffing the binaries yourself just seems like far too much work for an end-user.

As you can see here there is a very simple way to do that.

In your DialogFragment add an interface listener like:

public interface EditNameDialogListener {
    void onFinishEditDialog(String inputText);
}

Then, add a reference to that listener:

private EditNameDialogListener listener;

This will be used to "activate" the listener method(s), and also to check if the parent Activity/Fragment implements this interface (see below).

In the Activity/FragmentActivity/Fragment that "called" the DialogFragment simply implement this interface.

In your DialogFragment all you need to add at the point where you'd like to dismiss the DialogFragment and return the result is this:

listener.onFinishEditDialog(mEditText.getText().toString());
this.dismiss();

Where mEditText.getText().toString() is what will be passed back to the calling Activity.

Note that if you want to return something else simply change the arguments the listener takes.

Finally, you should check whether the interface was actually implemented by the parent activity/fragment:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    // Verify that the host activity implements the callback interface
    try {
        // Instantiate the EditNameDialogListener so we can send events to the host
        listener = (EditNameDialogListener) context;
    } catch (ClassCastException e) {
        // The activity doesn't implement the interface, throw exception
        throw new ClassCastException(context.toString()
                + " must implement EditNameDialogListener");
    }
}

This technique is very flexible and allow calling back with the result even if your don;t want to dismiss the dialog just yet.

You need convert to number type:

(+Low).toFixed(2)

when you set the density to 96, doesn't it look good?

when i tried it i saw that saving as jpg resulted with better quality, but larger file size

First of all, it is a bad design, if you need something like that, it is good idea to refactor, e.g. by renaming the method. Java allows calling of overriden method using the "super" keyword, but only one level up in the hierarchy, I am not sure, maybe Scala and some other JVM languages support it for any level.

In Postgress SQL:

Alter table student rename to student_details;

join() is a instance method of java.lang.Thread class which we can use join() method to ensure all threads that started from main must end in order in which they started and also main should end in last. In other words waits for this thread to die.

Exception: join() method throws InterruptedException.

Thread state: When join() method is called on thread it goes from running to waiting state. And wait for thread to die.

synchronized block: Thread need not to acquire object lock before calling join() method i.e. join() method can be called from outside synchronized block.

Waiting time: join(): Waits for this thread to die.

public final void join() throws InterruptedException;

This method internally calls join(0). And timeout of 0 means to wait forever;

join(long millis) – synchronized method Waits at most millis milliseconds for this thread to die. A timeout of 0 means to wait forever.

public final synchronized void join(long millis)
    throws InterruptedException;

public final synchronized void join(long millis, int nanos)
    throws InterruptedException;

Example of join method

class MyThread implements Runnable {
     public void run() {
           String threadName = Thread.currentThread().getName();
           Printer.print("run() method of "+threadName);
           for(int i=0;i<4;i++){
                Printer.print("i="+i+" ,Thread="+threadName);
           }         
     }
}

public class TestJoin {
     public static void main(String...args) throws InterruptedException {
           Printer.print("start main()...");

           MyThread runnable = new MyThread();
           Thread thread1=new Thread(runnable);
           Thread thread2=new Thread(runnable);

           thread1.start();
           thread1.join();

           thread2.start();
           thread2.join();

           Printer.print("end main()");
     }
}

class Printer {
     public static void print(String str) {
           System.out.println(str);
     }
}

Output:
     start main()...
     run() method of Thread-0
     i=0 ,Thread=Thread-0
     i=1 ,Thread=Thread-0
     i=2 ,Thread=Thread-0
     i=3 ,Thread=Thread-0
     run() method of Thread-1
     i=0 ,Thread=Thread-1
     i=1 ,Thread=Thread-1
     i=2 ,Thread=Thread-1
     i=3 ,Thread=Thread-1
     end main()

Note: calling thread1.join() made main thread to wait until Thread-1 dies.

Let’s check a program to use join(long millis)

First, join(1000) will be called on Thread-1, but once 1000 millisec are up, main thread can resume and start thread2 (main thread won’t wait for Thread-1 to die).

class MyThread implements Runnable {
     public void run() {
           String threadName = Thread.currentThread().getName();
           Printer.print("run() method of "+threadName);
           for(int i=0;i<4;i++){
                try {
                     Thread.sleep(500);
                } catch (InterruptedException e) {
                     e.printStackTrace();
                }
                Printer.print("i="+i+" ,Thread="+threadName);
           }         
     }
}

public class TestJoin {
     public static void main(String...args) throws InterruptedException {
           Printer.print("start main()...");

           MyThread runnable = new MyThread();
           Thread thread1=new Thread(runnable);
           Thread thread2=new Thread(runnable);

           thread1.start();

           // once 1000 millisec are up,
           // main thread can resume and start thread2.
           thread1.join(1000);

           thread2.start();
           thread2.join();

           Printer.print("end main()");
     }
}

class Printer {
     public static void print(String str) {
           System.out.println(str);
     }
}

Output:
     start main()...
     run() method of Thread-0
     i=0 ,Thread=Thread-0
     run() method of Thread-1
     i=1 ,Thread=Thread-0
     i=2 ,Thread=Thread-0
     i=0 ,Thread=Thread-1
     i=1 ,Thread=Thread-1
     i=3 ,Thread=Thread-0
     i=2 ,Thread=Thread-1
     i=3 ,Thread=Thread-1
     end main()

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

It's because of the Python version. In Python 3 it's import Queue as queue; on the contrary in Python 2.x it's import queue. If you want it for both environments you may use something below as mentioned here

try:
   import queue
except ImportError:
   import Queue as queue
