The simple solution is to just remap coordinates from the original to the final image, copying pixels from one coordinate space to the other, rounding off as necessary -- which may result in some pixels being copied several times adjacent to each other, and other pixels being skipped, depending on whether you're stretching or shrinking (or both) in either dimension. Make sure your copying iterates through the destination space, so all pixels are covered there even if they're painted more than once, rather than thru the source which may skip pixels in the output.

The better solution involves calculating the corresponding source coordinate without rounding, and then using its fractional position between pixels to compute an appropriate average of the (typically) four pixels surrounding that location. This is essentially a filtering operation, so you lose some resolution -- but the result looks a LOT better to the human eye; it does a much better job of retaining small details and avoids creating straight-line artifacts which humans find objectionable.

Note that the same basic approach can be used to remap flat images onto any other shape, including 3D surface mapping.

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

4 steps

1. npm install dotenv --save

2. Next add the following line to your app.

   require('dotenv').config()

3. Then create a .env file at the root directory of your application and add the variables to it.

// contents of .env 

REACT_APP_API_KEY = 'my-secret-api-key'

4. Finally, add .env to your .gitignore file so that Git ignores it and it never ends up on GitHub.

If you are using create-react-app then you only need step 3 and 4 but keep in mind variable needs to start with REACT_APP_ for it to work.

Reference: https://create-react-app.dev/docs/adding-custom-environment-variables/

NOTE - Need to restart application after adding variable in .env file.

You should set responseType: ResponseContentType.Blob in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.

Here is an working example:

Create image.service.ts and put following code:

Angular 4:

getImage(imageUrl: string): Observable<File> {
    return this.http
        .get(imageUrl, { responseType: ResponseContentType.Blob })
        .map((res: Response) => res.blob());
}

Angular 5+:

getImage(imageUrl: string): Observable<Blob> {
  return this.httpClient.get(imageUrl, { responseType: 'blob' });
}

Important: Since Angular 5+ you should use the new HttpClient.

The new HttpClient returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'. Read more about that here.

Now you need to create some function in your image.component.ts to get image and show it in html.

For creating an image from Blob you need to use JavaScript's FileReader. Here is function which creates new FileReader and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:

imageToShow: any;

createImageFromBlob(image: Blob) {
   let reader = new FileReader();
   reader.addEventListener("load", () => {
      this.imageToShow = reader.result;
   }, false);

   if (image) {
      reader.readAsDataURL(image);
   }
}

Now you should use your created ImageService to get image from api. You should to subscribe to data and give this data to createImageFromBlob-function. Here is an example function:

getImageFromService() {
      this.isImageLoading = true;
      this.imageService.getImage(yourImageUrl).subscribe(data => {
        this.createImageFromBlob(data);
        this.isImageLoading = false;
      }, error => {
        this.isImageLoading = false;
        console.log(error);
      });
}

Now you can use your imageToShow-variable in HTML template like this:

<img [src]="imageToShow"
     alt="Place image title"
     *ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
     <img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>

I hope this description is clear to understand and you can use it in your project.

See the working example for Angular 5+ here.

It works for me for opening small text file... I didn't try in other file

protected void viewhelper(Intent intent) {
    Uri a = intent.getData();
    if (!a.toString().startsWith("content:")) {
        return;
    }
    //Ok Let's do it
    String content = readUri(a);
    //do something with this content
}

here is the readUri(Uri uri) method

private String readUri(Uri uri) {
    InputStream inputStream = null;
    try {
        inputStream = getContentResolver().openInputStream(uri);
        if (inputStream != null) {
            byte[] buffer = new byte[1024];
            int result;
            String content = "";
            while ((result = inputStream.read(buffer)) != -1) {
                content = content.concat(new String(buffer, 0, result));
            }
            return content;
        }
    } catch (IOException e) {
        Log.e("receiver", "IOException when reading uri", e);
    } finally {
        if (inputStream != null) {
            try {
                inputStream.close();
            } catch (IOException e) {
                Log.e("receiver", "IOException when closing stream", e);
            }
        }
    }
    return null;
}

I got it from this repository https://github.com/zhutq/android-file-provider-demo/blob/master/FileReceiver/app/src/main/java/com/demo/filereceiver/MainActivity.java
I modified some code so that it work.

Manifest file:

    <activity android:name=".MainActivity">
        <intent-filter >
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:mimeType="*/*" />
        </intent-filter>
    </activity>

You need to add

@Override
protected void onCreate(Bundle savedInstanceState) {
    /*
     *    Your OnCreate
     */
    Intent intent = getIntent();
    String action = intent.getAction();
    String type = intent.getType();

    //VIEW"
    if (Intent.ACTION_VIEW.equals(action) && type != null) {
        viewhelper(intent); // Handle text being sent
    }
  }

I wrote an extension that takes into account all possible cases:

• If access is allowed, then the code onAccessHasBeenGranted will be run.
• If access is not determined, then requestAuthorization(_:) will be called.
• If the user has denied your app photo library access, then the user will be shown a window offering to go to settings and allow access. In this window, the "Cancel" and "Settings" buttons will be available to him. When he presses the "settings" button, your application settings will open.

Usage example:

PHPhotoLibrary.execute(controller: self, onAccessHasBeenGranted: {
    // access granted... 
})

Extension code:

import Photos
import UIKit

public extension PHPhotoLibrary {

   static func execute(controller: UIViewController,
                       onAccessHasBeenGranted: @escaping () -> Void,
                       onAccessHasBeenDenied: (() -> Void)? = nil) {

      let onDeniedOrRestricted = onAccessHasBeenDenied ?? {
         let alert = UIAlertController(
            title: "We were unable to load your album groups. Sorry!",
            message: "You can enable access in Privacy Settings",
            preferredStyle: .alert)
         alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
         alert.addAction(UIAlertAction(title: "Settings", style: .default, handler: { _ in
            if let settingsURL = URL(string: UIApplication.openSettingsURLString) {
               UIApplication.shared.open(settingsURL)
            }
         }))
         controller.present(alert, animated: true)
      }

      let status = PHPhotoLibrary.authorizationStatus()
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAccessHasBeenGranted)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAccessHasBeenGranted()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   }

}

private func onNotDetermined(_ onDeniedOrRestricted: @escaping (()->Void), _ onAuthorized: @escaping (()->Void)) {
   PHPhotoLibrary.requestAuthorization({ status in
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAuthorized)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAuthorized()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   })
}

values_of_objArray = [
  { id: 3432, name: "Recent" },
  { id: 3442, name: "Most Popular" },
  { id: 3352, name: "Rating" }
];

private ValueId : number = 0 // this will be used for multi access like 
                             // update, deleting the obj with id.
private selectedObj : any;

private selectedValueObj(id: any) {
  this.ValueId = (id.srcElement || id.target).value;
  for (let i = 0; i < this.values_of_objArray.length; i++) {
    if (this.values_of_objArray[i].id == this.ValueId) {
      this.selectedObj = this.values_of_objArray[i];
    }
  }
}

Now play with this.selectedObj which has the selected obj from the view.

HTML:

<select name="values_of_obj" class="form-control" [(ngModel)]="ValueId"  
        (change)="selectedValueObj($event)" required>

  <option *ngFor="let Value of values_of_objArray"
          [value]="Value.id">{{Value.name}}</option>    
</select>

Use Safe Pipe to fix it.

• Create a safe pipe if u haven't any.

  ng g pipe safe

• add Safe pipe in app.module.ts

  declarations: [SafePipe]

• declare safe pipe in your ts

Import Dom Sanitizer and Safe Pipe to access url safely

import { Pipe, PipeTransform} from '@angular/core';
import { DomSanitizer } from "@angular/platform-browser";

@Pipe({ name: 'safe' })

export class SafePipe implements PipeTransform {

constructor(private sanitizer: DomSanitizer) { }
transform(url) {
 return this.sanitizer.bypassSecurityTrustResourceUrl(url);
  }
}

• Add safe with src url

  <img width="900" height="500" [src]="link | safe"/>

You should store your images, css and JS files in a public directory. To create a link to any of them, use asset() helper:

{{ asset('img/myimage.png') }}

https://laravel.com/docs/5.1/helpers#method-asset

As alternative, you could use amazing Laravel Collective package for building forms and HTML elements, so your code will look like this:

{{ HTML::image('img/myimage.png', 'a picture') }}

This library, BottomNavigationViewEx, extends Google's BottomNavigationView. You can easily customise Google's library to have bottom navigation bar the way you want it to be. You can disable the shifting mode, change visibility of the icons and texts and so much more. Definitely try it out.

Bootstrap v4.1 uses new classnames for hiding columns on their grid system.

For hiding columns depending on the screen width, use d-none class or any of the d-{sm,md,lg,xl}-none classes. To show columns on certain screen sizes, combine the above mentioned classes with d-block or d-{sm,md,lg,xl}-block classes.

Examples are:

<div class="d-lg-none">hide on screens wider than lg</div>_x000D_
<div class="d-none d-lg-block">hide on screens smaller than lg</div>

More of these here.

The REST API of Instagram has been discontinued. But you can use GraphQL to get the desired data. Here you can find an overview: https://developers.facebook.com/docs/instagram-api

For client side files, you cannot get a list of files in a user's local directory.

If the user has provided uploaded files, you can access them via their input element.

<input type="file" name="client-file" id="get-files" multiple />


<script>
var inp = document.getElementById("get-files");
// Access and handle the files 

for (i = 0; i < inp.files.length; i++) {
    let file = inp.files[i];
    // do things with file
}
</script>

Unwrap and downcast the objects to the right type, safely, with if let, before doing the iteration with a simple for in loop.

if let currentUser = currentUser, 
    let photos = currentUser.photos as? [ModelAttachment] 
{
    for object in photos {
        let url = object.url
    }
}

There's also guard let else instead of if let if you prefer having the result available in scope:

guard let currentUser = currentUser, 
    let photos = currentUser.photos as? [ModelAttachment] else 
{
    // break or return
}
// now 'photos' is available outside the guard
for object in photos {
    let url = object.url
}

Several of the questions/comments I've seen around this subject sound to me as if the person is using Namespace where they mean 'module alias'. As Ryan Cavanaugh mentioned in one of his comments you can have a 'Wrapper' module re-export several modules.

If you really want to import it all from the same module name/alias, combine a wrapper module with a paths mapping in your tsconfig.json.

Example:

./path/to/CompanyName.Products/Foo.ts

export class Foo {
    ...
}

./path/to/CompanyName.Products/Bar.ts

export class Bar {
    ...
}

./path/to/CompanyName.Products/index.ts

export { Foo } from './Foo';
export { Bar } from './Bar';

tsconfig.json

{
    "compilerOptions": {
        ...
        paths: {
            ...
            "CompanyName.Products": ["./path/to/CompanyName.Products/index"],
            ...
        }
        ...
    }
    ...
}

main.ts

import { Foo, Bar } from 'CompanyName.Products'

Note: The module resolution in the output .js files will need to be handled somehow, such as with this https://github.com/tleunen/babel-plugin-module-resolver

Example .babelrc to handle the alias resolution:

{
    "plugins": [
        [ "module-resolver", {
            "cwd": "babelrc",
            "alias": {
                "CompanyName.Products": "./path/to/typescript/build/output/CompanyName.Products/index.js"
            }
        }],
        ... other plugins ...
    ]
}

Xcode 10.1 • Swift 4.2

                           y: superview.frame.midY - strLabel.frame.height / 2, width: 160, height: 46)

            layer.cornerRadius = 15.0
            layer.masksToBounds = true

            activityIndicator.frame = CGRect(x: 0, y: 0, width: 46, height: 46)
            activityIndicator.startAnimating()

            strLabel.text = title
            strLabel.font = .systemFont(ofSize: 14, weight: UIFont.Weight.medium)

            switch theme {
            case .dark:
                strLabel.textColor = .white
                activityIndicator.style = .white
            default:
                strLabel.textColor = .gray
                activityIndicator.style = .gray
            }
        }

    func show() {
        self.isHidden = false
    }

    func hide() {
        self.isHidden = true
    }
}

Use:

let progress = ProgressHUD(title: "Authorization", theme: .dark)
[progress].forEach(view.addSubview(_:))

I have been busy using different posts and methods for two days trying to figure it out. I urge anyone to START by looking at the post by Eggs, and mess around with the codepen he and others have built.

This has been the only solution to work properly for me that I have found. I recommend his answer as a solution/ a good starting point at minimum for those of us still figuring out this problem in our own web applications.

I haven't gotten enough reputation yet to comment on his post, otherwise I would. I can't even vote on it yet or I would do that too.

This is the actual code I used:

html::before {
    content: ' ';
    display: block;
    background-image: url('path-to-your-image');
    background-position: bottom left; 
    /*For my instance this is how I have built my bg image. Indexes off the 
bottom left for consistency*/
    background-size: cover;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    position: fixed;
    z-index: -10; 
    /*I haven't tested my full app functionality after changing the z-index, but everything appears to work flawlessly right now.*/
}

I tried everything with his original code. When I had

background-position: center; 

chrome (on latest android update as of 1/8/18) would lag with updating the image's position, so when scrolling through the website there would be a patch of color where my navbar/URL bar of the browser was. Then it would disappear after the browser recalculated the image center(is what I assume was happening).

So, I recommend making an image around your footer or header like I did, and setting either top left/right or bottom left/right for your position.

In summary, THIS WORKS for me. So try it out if you're reading down this far and nothing has worked yet. Though you should've already hit the original post by now.

Thank you Eggs, and the other fellows you collaborated with on your Codepen.

Call it from your viewcontroller like this:

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

Also don't forget to include the following keys in your info.plist:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

This chains work in my case:

1. git rm -r WebApplication/packages

There was a confirmation git-dialog. You should choose "y" option.

2. git commit -m "blabla"
3. git push -f origin <ur_branch>

Depending whether or not you know the image format, here are ways you can do it :

Download Image to a file, knowing the image format

using (WebClient webClient = new WebClient()) 
{
   webClient.DownloadFile("http://yoururl.com/image.png", "image.png") ; 
}

Download Image to a file without knowing the image format

You can use Image.FromStream to load any kind of usual bitmaps (jpg, png, bmp, gif, ... ), it will detect automaticaly the file type and you don't even need to check the url extension (which is not a very good practice). E.g:

using (WebClient webClient = new WebClient()) 
{
    byte [] data = webClient.DownloadData("https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t34.0-12/10555140_10201501435212873_1318258071_n.jpg?oh=97ebc03895b7acee9aebbde7d6b002bf&oe=53C9ABB0&__gda__=1405685729_110e04e71d9");

   using (MemoryStream mem = new MemoryStream(data)) 
   {
       using (var yourImage = Image.FromStream(mem)) 
       { 
          // If you want it as Png
           yourImage.Save("path_to_your_file.png", ImageFormat.Png) ; 

          // If you want it as Jpeg
           yourImage.Save("path_to_your_file.jpg", ImageFormat.Jpeg) ; 
       }
   } 

}

Note : ArgumentException may be thrown by Image.FromStream if the downloaded content is not a known image type.

Check this reference on MSDN to find all format available. Here are reference to WebClient and Bitmap.

Similar to the other examples, but using html sizing, I use:

<img src="image1.png" width="425"/> <img src="image2.png" width="425"/> 

Here is an example

<img src="https://openclipart.org/image/2400px/svg_to_png/28580/kablam-Number-Animals-1.png" width="200"/> <img src="https://openclipart.org/download/71101/two.svg" width="300"/>

I tested this using Remarkable.

If some of you, like me, encounter orientation problems I have combined the solutions here with a exif orientation fix

https://gist.github.com/SagiMedina/f00a57de4e211456225d3114fd10b0d0

I had a similar problem and for me it boiled down to adding the following HTTP headers at the response of the receiving end:

Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *

You may prefer not to use the * at the end, but only the domainname of the host sending the data. Like *.example.com

But this is only feasible when you have access to the configuration of the server.

This worked for my purposes. Pretty basic and simple, but it did what I needed (which was to get a personal photo of mine onto the internet so I could use its URL).

1. Go to photos.google.com and open any image that you wish to embed in your website.

2. Tap the Share Icon and then choose "Get Link" to generate a shareable link for that image.

3. Go to j.mp/EmbedGooglePhotos, paste that link and it will instantly generate the embed code for that picture.

4. Open your website template, paste the generated code and save. The image will now serve directly from your Google Photos account.

To get rid of the outline when clicking, add outline:none

jsFiddle example

button {
    background-color: Transparent;
    background-repeat:no-repeat;
    border: none;
    cursor:pointer;
    overflow: hidden;
    outline:none;
}

button {_x000D_
    background-color: Transparent;_x000D_
    background-repeat:no-repeat;_x000D_
    border: none;_x000D_
    cursor:pointer;_x000D_
    overflow: hidden;_x000D_
    outline:none;_x000D_
}

<button>button</button>

I guess your app crashes because of NullPointerException.

Change this

ListView lv = (ListView)getActivity().findViewById(R.id.lv_contact);

to

ListView lv = (ListView)rootView.findViewById(R.id.lv_contact);

assuming listview belongs to the fragment layout.

The rest of the code looks alright

Edit:

Well since you said it is not working i tried it myself

you can do this with css3, this blurs the whole element

div (or whatever element) {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
}

Fiddle: http://jsfiddle.net/H4DU4/

I've written a little php script which rotates the image. Be sure to store the image in favour of just recalculate it each request.

<?php

header("Content-type: image/jpeg");
$img = 'IMG URL';

$exif = @exif_read_data($img,0,true);
$orientation = @$exif['IFD0']['Orientation'];
if($orientation == 7 || $orientation == 8) {
    $degrees = 90;
} elseif($orientation == 5 || $orientation == 6) {
    $degrees = 270;
} elseif($orientation == 3 || $orientation == 4) {
    $degrees = 180;
} else {
    $degrees = 0;
}
$rotate = imagerotate(imagecreatefromjpeg($img), $degrees, 0);
imagejpeg($rotate);
imagedestroy($rotate);

?>

Give unique class and different id for file input

           $("#tab-content").on('change',class,function()
               {
                  var id=$(this).attr('id');
                      $("#"+id).trigger(your function); 
               //for name of file input  $("#"+id).attr("name");
               });

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

I use outline a css 2 property that simply works. Check this out, is simple and even easy to animate:

.double-border {_x000D_
  display: block;_x000D_
  clear: both;_x000D_
  background: red;_x000D_
  border: 5px solid yellow;_x000D_
  outline: 5px solid blue;_x000D_
  transition: 0.7s all ease-in;_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
}_x000D_
.double-border:hover {_x000D_
  background: yellow;_x000D_
  outline-color: red;_x000D_
  border-color: blue;_x000D_
}

<div class="double-border"></div>

.article-img img{ 
    height: 100%;
    width: 100%;
    position: relative;
    vertical-align: middle;
    border-style: none;
 }

You will make images size same as div and you can use bootstrap grid to manipulate div size accordingly

Main Activity

public class MainActivity extends Activity {

    EditText user, password;
    Button login;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        user = (EditText) findViewById(R.id.username_edit);
        password = (EditText) findViewById(R.id.edit_password);
        login = (Button) findViewById(R.id.btnSubmit);
        login.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this,Second.class);

                String uservalue = user.getText().toString();
                String name_value = password.getText().toString();
                String password_value = password.getText().toString();

                intent.putExtra("username", uservalue);
                intent.putExtra("password", password_value);
                startActivity(intent);
            }
        });
    }
}

Second Activity in which you want to receive Data

public class Second extends Activity{

    EditText name, pass;
    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.second_activity);

        name = (EditText) findViewById(R.id.editText1);
        pass = (EditText) findViewById(R.id.editText2);

        String value = getIntent().getStringExtra("username");
        String pass_val = getIntent().getStringExtra("password");
        name.setText(value);
        pass.setText(pass_val);
    }
}

Since Trung Le Nguyen Nhat's fiddle isn't correct at all (it just uses the original image in the last step)
I wrote my own general fiddle with performance comparison:

FIDDLE

Basically it's:

img.onload = function() {
   var canvas = document.createElement('canvas'),
       ctx = canvas.getContext("2d"),
       oc = document.createElement('canvas'),
       octx = oc.getContext('2d');

   canvas.width = width; // destination canvas size
   canvas.height = canvas.width * img.height / img.width;

   var cur = {
     width: Math.floor(img.width * 0.5),
     height: Math.floor(img.height * 0.5)
   }

   oc.width = cur.width;
   oc.height = cur.height;

   octx.drawImage(img, 0, 0, cur.width, cur.height);

   while (cur.width * 0.5 > width) {
     cur = {
       width: Math.floor(cur.width * 0.5),
       height: Math.floor(cur.height * 0.5)
     };
     octx.drawImage(oc, 0, 0, cur.width * 2, cur.height * 2, 0, 0, cur.width, cur.height);
   }

   ctx.drawImage(oc, 0, 0, cur.width, cur.height, 0, 0, canvas.width, canvas.height);
}

Why use the canvas to resize images? Modern browsers all use bicubic interpolation — the same process used by Photoshop (if you're doing it right) — and they do it faster than the canvas process. Just specify the image size you want (use only one dimension, height or width, to resize proportionally).

This is supported by most browsers, including later versions of IE. Earlier versions may require browser-specific CSS.

A simple function (using jQuery) to resize an image would be like this:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

Then just use the returned value to resize the image in one or both dimensions.

Obviously there are different refinements you could make, but this gets the job done.

Paste the following code into the console of this page and watch what happens to the gravatars:

function resizeImage(img, percentage) {
    var coeff = percentage/100,
        width = $(img).width(),
        height = $(img).height();

    return {"width": width*coeff, "height": height*coeff}           
}

$('.user-gravatar32 img').each(function(){
  var newDimensions = resizeImage( this, 150);
  this.style.width = newDimensions.width + "px";
  this.style.height = newDimensions.height + "px";
});

You want an entity known as a cross mark:

http://www.fileformat.info/info/unicode/char/274c/index.htm

The code for it is ❌ and it displays like ❌

If you want a perfectly centered cross mark, like this:

try the following CSS:

div {
    height: 100px;
    width: 100px;
    background-color: #FA6900;
    border-radius: 5px;
    position: relative;
}

div:after {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    content: "\274c"; /* use the hex value here... */
    font-size: 50px; 
    color: #FFF;
    line-height: 100px;
    text-align: center;
}

See Demo Fiddle

Cross-Browser Issue

The cross-mark entity does not display with Safari or Chrome. However, the same entity displays well in Firefox, IE and Opera.

It is safe to use the smaller but similarly shaped multiplication sign entity, × which displays as ×.

<gradient android:startColor="#ffdd00"

@bogatron already gave the answer suggested by the matplotlib docs, which produces the right height, but it introduces a different problem. Now the width of the colorbar (as well as the space between colorbar and plot) changes with the width of the plot. In other words, the aspect ratio of the colorbar is not fixed anymore.

To get both the right height and a given aspect ratio, you have to dig a bit deeper into the mysterious axes_grid1 module.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable, axes_size
import numpy as np

aspect = 20
pad_fraction = 0.5

ax = plt.gca()
im = ax.imshow(np.arange(200).reshape((20, 10)))
divider = make_axes_locatable(ax)
width = axes_size.AxesY(ax, aspect=1./aspect)
pad = axes_size.Fraction(pad_fraction, width)
cax = divider.append_axes("right", size=width, pad=pad)
plt.colorbar(im, cax=cax)

Note that this specifies the width of the colorbar w.r.t. the height of the plot (in contrast to the width of the figure, as it was before).

The spacing between colorbar and plot can now be specified as a fraction of the width of the colorbar, which is IMHO a much more meaningful number than a fraction of the figure width.

UPDATE:

I created an IPython notebook on the topic, where I packed the above code into an easily re-usable function:

import matplotlib.pyplot as plt
from mpl_toolkits import axes_grid1

def add_colorbar(im, aspect=20, pad_fraction=0.5, **kwargs):
    """Add a vertical color bar to an image plot."""
    divider = axes_grid1.make_axes_locatable(im.axes)
    width = axes_grid1.axes_size.AxesY(im.axes, aspect=1./aspect)
    pad = axes_grid1.axes_size.Fraction(pad_fraction, width)
    current_ax = plt.gca()
    cax = divider.append_axes("right", size=width, pad=pad)
    plt.sca(current_ax)
    return im.axes.figure.colorbar(im, cax=cax, **kwargs)

It can be used like this:

im = plt.imshow(np.arange(200).reshape((20, 10)))
add_colorbar(im)

here you go Sir :-)

Client need to send base64 to server.

And above answer described code is work perfectly:

$imageData = base64_decode($imageData);
$source = imagecreatefromstring($imageData);
$rotate = imagerotate($source, $angle, 0); // if want to rotate the image
$imageSave = imagejpeg($rotate,$imageName,100);
imagedestroy($source);

Thanks

Well, as /?__a=1 stopped working by now, it's better to use curl and parse the instagram page as written at this answer: Generate access token Instagram API, without having to log in?

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

As the official specification says, "one or more different sets of data are combined in a single body". So when photos and music are handled as multipart messages as mentioned in the question, probably there is some plain text metadata associated as well, thus making the request containing different types of data (binary, text), which implies the usage of multipart.

cursor.execute(sql,array)

Only takes two arguments.
It will iterate the "array"-object and match ? in the sql-string.
(with sanity checks to avoid sql-injection)

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

First off, in order to have any image "resize" to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage

If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of the pciturebox and crop the rest, or start at the bottom, fill the height of the picturebox to the top, etc), and it should be fairly simple to use the Height / Width properties of both the picturebox and the image to clip the image and get the effect you are looking for.

(the resolution can't be changed if output=surface - that's the default).

If the file is in a public folder, you can use Google Drive website hosting.

Here's a relatively easy method to do this. Throw a GridView into your layout, setting the stretch mode to stretch the column widths, set the spacing to 0 (or whatever you want), and set the number of columns to 2:

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:verticalSpacing="0dp"
        android:horizontalSpacing="0dp"
        android:stretchMode="columnWidth"
        android:numColumns="2"/>

</FrameLayout>

Make a custom ImageView that maintains its aspect ratio:

src/com/example/graphicstest/SquareImageView.java

public class SquareImageView extends ImageView {
    public SquareImageView(Context context) {
        super(context);
    }

    public SquareImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SquareImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
    }
}

Make a layout for a grid item using this SquareImageView and set the scaleType to centerCrop:

res/layout/grid_item.xml

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <com.example.graphicstest.SquareImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"/>

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_gravity="bottom"
        android:textColor="@android:color/white"
        android:background="#55000000"/>

</FrameLayout>

Now make some sort of adapter for your GridView:

src/com/example/graphicstest/MyAdapter.java

private final class MyAdapter extends BaseAdapter {
    private final List<Item> mItems = new ArrayList<Item>();
    private final LayoutInflater mInflater;

    public MyAdapter(Context context) {
        mInflater = LayoutInflater.from(context);

        mItems.add(new Item("Red",       R.drawable.red));
        mItems.add(new Item("Magenta",   R.drawable.magenta));
        mItems.add(new Item("Dark Gray", R.drawable.dark_gray));
        mItems.add(new Item("Gray",      R.drawable.gray));
        mItems.add(new Item("Green",     R.drawable.green));
        mItems.add(new Item("Cyan",      R.drawable.cyan));
    }

    @Override
    public int getCount() {
        return mItems.size();
    }

    @Override
    public Item getItem(int i) {
        return mItems.get(i);
    }

    @Override
    public long getItemId(int i) {
        return mItems.get(i).drawableId;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        View v = view;
        ImageView picture;
        TextView name;

        if (v == null) {
            v = mInflater.inflate(R.layout.grid_item, viewGroup, false);
            v.setTag(R.id.picture, v.findViewById(R.id.picture));
            v.setTag(R.id.text, v.findViewById(R.id.text));
        }

        picture = (ImageView) v.getTag(R.id.picture);
        name = (TextView) v.getTag(R.id.text);

        Item item = getItem(i);

        picture.setImageResource(item.drawableId);
        name.setText(item.name);

        return v;
    }

    private static class Item {
        public final String name;
        public final int drawableId;

        Item(String name, int drawableId) {
            this.name = name;
            this.drawableId = drawableId;
        }
    }
}

Set that adapter to your GridView:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    GridView gridView = (GridView)findViewById(R.id.gridview);
    gridView.setAdapter(new MyAdapter(this));
}

And enjoy the results:

The <ul> element has browser inherent padding & margin by default. In your case, Use

#footer ul {
    margin: 0; /* To remove default bottom margin */ 
    padding: 0; /* To remove default left padding */
}

or a CSS browser reset ( https://cssreset.com/ ) to deal with this.

You can try : go to edit>preferencec>type.. select type > choose text engine options select east asian. Restart photoshop. Create new peroject. Try text tool again.

(if you want to use your project created with other text engine type) copy /paste all layers to new project.

To make certain file types OPEN on your computer, instead of Chrome Downloading...

You have to download the file type once, then right after that download, look at the status bar at the bottom of the browser. Click the arrow next to that file and choose "always open files of this type". DONE.

Now the file type will always OPEN using your default program.

To reset this feature, go to Settings / Advance Settings and under the "Download.." section, there's a button to reset 'all' Auto Downloads

Hope this helps.. :-)

You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.

You just need to re-open the image with IrfanView after changing the view color to white.

To change the viewing color in Irfanview go to:

Options > Properties/Settings > Viewing > Main window color

Actually, Laravel 4 does have a table rename function in Illuminate/Database/Schema/Builder.php, it's just undocumented at the moment: Schema::rename($from, $to);.

The Facebook API limit isn't really documented, but apparently it's something like: 600 calls per 600 seconds, per token & per IP. As the site is restricted, quoting the relevant part:

After some testing and discussion with the Facebook platform team, there is no official limit I'm aware of or can find in the documentation. However, I've found 600 calls per 600 seconds, per token & per IP to be about where they stop you. I've also seen some application based rate limiting but don't have any numbers.

As a general rule, one call per second should not get rate limited. On the surface this seems very restrictive but remember you can batch certain calls and use the subscription API to get changes.

As you can access the Graph API on the client side via the Javascript SDK; I think if you travel your request for photos from the client, you won't hit any application limit as it's the user (each one with unique id) who's fetching data, not your application server (unique ID).

This may mean a huge refactor if everything you do go through a server. But it seems like the best solution if you have so many request (as it'll give a breath to your server).

Else, you can try batch request, but I guess you're already going this way if you have big traffic.

If nothing of this works, according to the Facebook Platform Policy you should contact them.

If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).

Using collectionViewFlowLayout.sectionInset or collectionView:layout:insetForSectionAtIndex: are correct.

However, if your collectionView has multiple sections and you want to add margin to the whole collectionView, I recommend to use the scrollView contentInset :

UIEdgeInsets collectionViewInsets = UIEdgeInsetsMake(50.0, 0.0, 30.0, 0.0);
self.collectionView.contentInset = collectionViewInsets;
self.collectionView.scrollIndicatorInsets = UIEdgeInsetsMake(collectionViewInsets.top, 0, collectionViewInsets.bottom, 0);

You may debug using two ways:

1. Press CTRL+U to view page Source . Press CTRL+F to find "mystyles.css" in source . click on mystyles.css link and check if it is not showing "404 not found".

2. You can INSPECT ELEMENT IN FIRBUG and set path to Image ,Set Image height and width because sometimes image doesnt show up.

Hope this may works !!.

Perform rotation using transform: rotate(xdeg) and also apply overflow: hidden to the parent component to avoid overlapping effect

.div-parent {
   overflow: hidden
}

.div-child {
   transform: rotate(270deg);
}

If you have two buttons and have the same id call to your button click events like this:

Button btn1;
Button btn2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn1= (Button)findViewById(R.id.button1);

    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent(MainActivity.this,target.class);
            startActivity(intent);
        }
    });

    btn2=(Button) findViewById(R.id.button1);//Have same id call previous button---> button1

    btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

When you clicked button1, button2 will work and you cannot open your second activity.

In order to get rid of duplicates, you can group by drinks.id. But that way you'll get only one photo for each drinks.id (which photo you'll get depends on database internal implementation).

Though it is not documented, in case of MySQL, you'll get the photo with lowest id (in my experience I've never seen other behavior).

SELECT name, price, photo 
FROM drinks, drinks_photos 
WHERE drinks.id = drinks_id
GROUP BY drinks.id

you don't need to set the width of header in css, just put the background image as center using this code:

background: url("images/logo.png") no-repeat top center;

or you can just use img tag and put align="center" in the div

function getExtension($str) 
    {

          $i = strrpos($str,".");
         if (!$i) { return ""; } 

         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
    }

$valid_formats = array("jpg", "png", "gif", "bmp","jpeg","PNG","JPG","JPEG","GIF","BMP");

                        $actual_image_name = time().substr(str_replace(" ", "_", $txt), 5).".".$ext;
                        $tmp = $_FILES['photoimg']['tmp_name'];
                        if(move_uploaded_file($tmp, $path.$actual_image_name))
                            {


                            mysql_query("INSERT INTO users (uid, profile_image) VALUES ('$session_id' , '$actual_image_name')");

                                echo "<img src='uploads/".$actual_image_name."'  class='preview'>";
                            }
                        else
                            echo "Fail upload folder with read access.";
                    }
                    else
                    echo "Image file size max 1 MB";                    
                    }
                    else
                    echo "Invalid file format..";   
            }

        else
            echo "Please select image..!";

        exit;
    }

There is the instagram public API's tags section that can help you do this.

I've used the following JavaScript library with great success:

https://github.com/balupton/jquery-history

It supports the HTML5 history API as well as a fallback method (using #) for older browsers.

This library is essentially a polyfill around `history.pushState'.

What I had to do is (in Javascript) is go through all pages by using a recursive function. It's dangerouse as instagram users could have thousands of pictures i a part from that (so your have to controle it) I use this code: (count parameter I think , doesn't do much)

        instagramLoadDashboard = function(hash)
    {
        code = hash.split('=')[1];

        $('#instagram-pictures .images-list .container').html('').addClass('loading');


        ts = Math.round((new Date()).getTime() / 1000);
        url = 'https://api.instagram.com/v1/users/self/media/recent?count=200&min_timestamp=0&max_timestamp='+ts+'&access_token='+code;

        instagramLoadMediaPage(url, function(){

            galleryHTML = instagramLoadGallery(instagramData);
            //console.log(galleryHTML);
            $('#instagram-pictures .images-list .container').html(galleryHTML).removeClass('loading');
            initImages('#instagram-pictures');

            IGStatus = 'loaded';

        });

    };

    instagramLoadMediaPage = function (url, callback)
    {
        $.ajax({
                url : url,
                dataType : 'jsonp',
                cache : false,
                success:  function(response){

                                        console.log(response);

                                        if(response.code == '400')
                                        {
                                            alert(response.error_message);
                                            return false;
                                        }

                                        if(response.pagination.next_url !== undefined) {
                                            instagramData = instagramData.concat(response.data);
                                            return instagramLoadMediaPage(response.pagination.next_url,callback);
                                        }

                                        instagramData = instagramData.concat(response.data);
                                        callback.apply();
                                    }
        });
    };

    instagramLoadGallery = function(images)
    {
        galleryHTML ='<ul>';

        for(var i=0;i<images.length;i++)
        {
            galleryHTML += '<li><img src="'+images[i].images.thumbnail.url+'" width="120" id="instagram-'+images[i].id+' data-type="instagram" data-source="'+images[i].images.standard_resolution.url+'" class="image"/></li>';

        }

        galleryHTML +='</ul>';

        return galleryHTML;
    };

There some stuff related to print out a gallery of picture.

Color picker plugin for Interface Builder

There's a nice color picker from Panic which works well with IB: http://panic.com/~wade/picker/

Xcode plugin

This one gives you a GUI for choosing colors: http://www.youtube.com/watch?v=eblRfDQM0Go

Objective-C

UIColor *color = [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1.0];

Swift

let color = UIColor(red: 160/255, green: 97/255, blue: 5/255, alpha: 1.0)

Pods and libraries

There's a nice pod named MPColorTools: https://github.com/marzapower/MPColorTools

You can use display:inline-block with white-space:nowrap. Write like this:

.scrolls {
    overflow-x: scroll;
    overflow-y: hidden;
    height: 80px;
    white-space:nowrap
}
.imageDiv img {
    box-shadow: 1px 1px 10px #999;
    margin: 2px;
    max-height: 50px;
    cursor: pointer;
    display:inline-block;
    *display:inline;/* For IE7*/
    *zoom:1;/* For IE7*/
    vertical-align:top;
 }

Check this http://jsfiddle.net/YbrX3/

Really late reply for me, but I just suffered the pain of this problem as well.

What fixed it for me (after trying the Axis label settings and intervals from those screens, none of which worked!) was select the Horizontal Axis, then when you can see all the properties find Labels, and change LabelInterval to 1.

For some reason when I set this from the pop up properties screens it either never 'stuck' or it changes a slightly different value that didn't fix my issue.

Select fonts by specifying the weights you need on load

Font-families consist of several distinct fonts

For example, extra-bold will make the font look quite different in say, Photoshop, because you're selecting a different font. The same applies to italic font, which can look very different indeed. Setting font-weight:800 or font-style:italic may result in just a best effort of the web browser to fatten or slant the normal font in the family.

Even though you're loading a font-family, you must specify the weights and styles you need for some web browsers to let you select a different font in the family with font-weight and font-style.

Example

This example specifies the light, normal, normal italic, bold, and extra-bold fonts in the font family Open Sans:

<html>_x000D_
  <head>_x000D_
    <link rel="stylesheet"_x000D_
          href="https://fonts.googleapis.com/css?family=Open+Sans:100,400,400i,600,800">_x000D_
    <style>_x000D_
      body {_x000D_
        font-family: 'Open Sans', serif;_x000D_
        font-size: 48px;_x000D_
      }_x000D_
    </style>_x000D_
  </head>_x000D_
  <body>    _x000D_
    <div style="font-weight:400">Didn't work with all the fonts</div>_x000D_
   <div style="font-weight:600">Didn't work with all the fonts</div>_x000D_
   <div style="font-weight:800">Didn't work with all the fonts</div>_x000D_
  </body>_x000D_
</html>

Testing

Tested working in Firefox 66.0.3 on Mac and Firefox 36.0.1 in Windows.

Non-Google fonts

Other fonts must be uploaded to the server, style and weight specified by their individual names.

System fonts

Assume nothing, font-wise, about what device is visiting your website or what fonts are installed on its OS.

(You may use the fall-backs of serif and sans-serif, but you will get the font mapped to these by the individual web browser version used, within the fonts available in the OS version it's running under, and not what you designed.)

Testing should be done with the font temporarily uninstalled from your system, to be sure that your design is in effect.

Box shadows can use commas to have multiple effects, just like with background images (in CSS3).

I don't know that you can do it in Chrome outside of Windows -- some Googling shows that Chrome (and therefore possibly Chromium) might respond well to a certain registry hack.

However, if you're just looking for a simple solution without modifying your code base, have you considered Firefox? In the about:config you can search for "network.http.max" and there are a few values in there that are definitely worth looking at.

Also, for a device that will not be moving (i.e. it is mounted in a fixed location) you should consider not using Wi-Fi (even a Home-Plug would be a step up as far as latency / stability / dropped connections go).

I had this error message show up for me because I was using the network on the main thread and new versions of Android have a "strict" policy to prevent that. To get around it just throw whatever network connection call into an AsyncTask.

Example:

    AsyncTask<CognitoCachingCredentialsProvider, Integer, Void> task = new AsyncTask<CognitoCachingCredentialsProvider, Integer, Void>() {

        @Override
        protected Void doInBackground(CognitoCachingCredentialsProvider... params) {
            AWSSessionCredentials creds = credentialsProvider.getCredentials();
            String id = credentialsProvider.getCachedIdentityId();
            credentialsProvider.refresh();
            Log.d("wooohoo", String.format("id=%s, token=%s", id, creds.getSessionToken()));
            return null;
        }
    };

    task.execute(credentialsProvider);

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

If you have "something" and need 'something', use replace(col, "\"", "\'") and viceversa.

Check out a module I've written (you can use it in browser) which converts exif orientation to CSS transform: https://github.com/Sobesednik/exif2css

There is also this node program to generate JPEG fixtures with all orientations: https://github.com/Sobesednik/generate-exif-fixtures

Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.

It depends on what type of fading you are looking for.

But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

http://jsfiddle.net/tLu7u/

also.. http://css3pie.com/

You can try this:

for file in *.jpg;
do
  mv $file $somestring_${file:((-7))}
done

You can see "parameter expansion" in man bash to understand the above better.

The following strategies all make a call to the database to perform a COUNT(*) query.

Model.count

Model.all.size

records = Model.all
records.count

The following is not as efficient as it will load all records from the database into Ruby, which then counts the size of the collection.

records = Model.all
records.size

If your models have associations and you want to find the number of belonging objects (e.g. @customer.orders.size), you can avoid database queries (disk reads). Use a counter cache and Rails will keep the cache value up to date, and return that value in response to the size method.

Had the same problem and the solution was to reauthorize the user. Check it here:

<?php

 require_once("src/facebook.php");

  $config = array(
      'appId' => '1424980371051918',
      'secret' => '2ed5c1260daa4c44673ba6fbc348c67d',
      'fileUpload' => false // optional
  );

  $facebook = new Facebook($config);

//Authorizing app:

?>
<a href="<?php echo $facebook->getLoginUrl(); ?>">Login con fb</a>

Saved project and opened on my test enviroment and it worked again. As I did, you can comment your previous code and try.

You just have to set UIFileSharingEnabled (Application Supports iTunes file sharing) key in the info plist of your app. Here's a link for the documentation. Scroll down to the file sharing support part.

In the past, it was also necessary to define CFBundleDisplayName (Bundle Display Name), if it wasn't already there. More details here.

<script>
$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?",
{
  format: "json"
},
//RETURNED RESPONSE DATA IS LOOPED AND ONLY IMAGE IS APPENDED TO IMAGE DIV
function(data) {
  $.each(data.items, function(i,item){
  $("<img/>").attr("src", item.media.m).appendTo("#images");

 });
});</script>
</body>
</html> 

The above code helps in getting images from the Flicker API. This uses the GET method for getting images using JSONP. It can be found in detail in here

Unfortunately, no. This feature is not available for facebook albums.

To get the actual access_token, you can also do pro grammatically via the following PHP code:

 require 'facebook.php';

 $facebook = new Facebook(array(
   'appId'  => 'YOUR_APP_ID',
   'secret' => 'YOUR_APP_SECRET',
 ));

 // Get User ID
 $user = $facebook->getUser();

 if ($user) {
   try {
     $user_profile = $facebook->api('/me');
     $access_token = $facebook->getAccessToken();
   } catch (FacebookApiException $e) {
     error_log($e);
     $user = null;
   }
 }

For the record, as far as I can tell, you had two problems:

1. You weren't passing a "jsonp" type specifier to your $.get, so it was using an ordinary XMLHttpRequest. However, your browser supported CORS (Cross-Origin Resource Sharing) to allow cross-domain XMLHttpRequest if the server OKed it. That's where the Access-Control-Allow-Origin header came in.

2. I believe you mentioned you were running it from a file:// URL. There are two ways for CORS headers to signal that a cross-domain XHR is OK. One is to send Access-Control-Allow-Origin: * (which, if you were reaching Flickr via $.get, they must have been doing) while the other was to echo back the contents of the Origin header. However, file:// URLs produce a null Origin which can't be authorized via echo-back.

The first was solved in a roundabout way by Darin's suggestion to use $.getJSON. It does a little magic to change the request type from its default of "json" to "jsonp" if it sees the substring callback=? in the URL.

That solved the second by no longer trying to perform a CORS request from a file:// URL.

To clarify for other people, here are the simple troubleshooting instructions:

1. If you're trying to use JSONP, make sure one of the following is the case:
   • You're using $.get and set dataType to jsonp.
   • You're using $.getJSON and included callback=? in the URL.
2. If you're trying to do a cross-domain XMLHttpRequest via CORS...
   1. Make sure you're testing via http://. Scripts running via file:// have limited support for CORS.
   2. Make sure the browser actually supports CORS. (Opera and Internet Explorer are late to the party)

Just in case you just need to show a picture in response to a camera request, there is image-to-camera.

Just download, build, install, copy an image of your choice to the device, and you can select it via the app, which is an alternative to the built-in camera.

Sorry I'm late, but speaking about text-shadow, I thought you would also like this example (I use it quite often when I need good shadows on text):

    -1.5px -2px lightblue;

Updated answer, nearly 5 years later:

The code in the original answer no longer works reliably, as images from various sources sometimes return with a different content URI, i.e. content:// rather than file://. A better solution is to simply use context.getContentResolver().openInputStream(intent.getData()), as that will return an InputStream that you can handle as you choose.

For example, BitmapFactory.decodeStream() works perfectly in this situation, as you can also then use the Options and inSampleSize field to downsample large images and avoid memory problems.

However, things like Google Drive return URIs to images which have not actually been downloaded yet. Therefore you need to perform the getContentResolver() code on a background thread.

Original answer:

The other answers explained how to send the intent, but they didn't explain well how to handle the response. Here's some sample code on how to do that:

protected void onActivityResult(int requestCode, int resultCode, 
       Intent imageReturnedIntent) {
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

    switch(requestCode) { 
    case REQ_CODE_PICK_IMAGE:
        if(resultCode == RESULT_OK){  
            Uri selectedImage = imageReturnedIntent.getData();
            String[] filePathColumn = {MediaStore.Images.Media.DATA};

            Cursor cursor = getContentResolver().query(
                               selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String filePath = cursor.getString(columnIndex);
            cursor.close();


            Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
        }
    }
}

After this, you've got the selected image stored in "yourSelectedImage" to do whatever you want with. This code works by getting the location of the image in the ContentResolver database, but that on its own isn't enough. Each image has about 18 columns of information, ranging from its filepath to 'date last modified' to the GPS coordinates of where the photo was taken, though many of the fields aren't actually used.

To save time as you don't actually need the other fields, cursor search is done with a filter. The filter works by specifying the name of the column you want, MediaStore.Images.Media.DATA, which is the path, and then giving that string[] to the cursor query. The cursor query returns with the path, but you don't know which column it's in until you use the columnIndex code. That simply gets the number of the column based on its name, the same one used in the filtering process. Once you've got that, you're finally able to decode the image into a bitmap with the last line of code I gave.

The only one that worked for me was a mix of all the answers:

convert in.png -background white -alpha remove -flatten -alpha off out.png

If you're simply trying to resize an image, I'd recommend setting width and height of the image with CSS. Here's a quick example:

.small-image {
    width: 100px;
    height: 100px;
}

Note that the height and width can also be set using JavaScript. Here's quick code sample:

var img = document.getElement("my-image");
img.style.width = 100 + "px";  // Make sure you add the "px" to the end,
img.style.height = 100 + "px"; // otherwise you'll confuse IE

Also, to ensure that the resized image looks good, add the following css rules to image selector:

• -ms-interpolation-mode: bicubic: introduce in IE7
• image-rendering: optimizeQuality: introduced in FireFox 3.6

As far as I can tell, all browsers except IE using an bicubic algorithm to resize images by default, so your resized images should look good in Firefox and Chrome.

If setting the css width and height doesn't work, you may want to play with a css transform:

• -moz-transform: scale(sx[, sy])
• -webkit-transform:scale(sx[, sy])

If for whatever reason you need to use a canvas, please note that there are two ways an image can be resize: by resizing the canvas with css or by drawing the image at a smaller size.

See this question for more details.

As others have said, you don't want to round your corners. You want to ship flat (no layers or alpha) square graphics. Apple changed the mask they use for rounding your corners in iOS7 and then again in iOS8. You can find these masks inside your Xcode application bundle. The path changes with every new SDK version they release. So, I'll show you how you can always find it.

find /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs -name 'MobileIcons.framework'

At this very moment, the path found by that command is /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/MobileIcons.framework but don't trust that. Use the command to find it yourself.

That path points to a directory with these files (again, at the time of this post)

As you can see, there are a lot of different masks, but they are named pretty clearly. Here is the AppIconMask@3x~iphone.png image:

You can use that to test your icon to see if it will look okay after it is masked. But, don't round your corners. If you do, when Apple changes those masks again, you will have artifacts.

The data still exists out in github, you can create a new branch from the old data:

git checkout origin/BranchName #get a readonly pointer to the old branch
git checkout –b BranchName #create a new branch from the old
git push origin BranchName #publish the new branch

CSS:

form div {
  padding: x; /*default div padding in the form e.g. 5px 0 5px 0*/
  margin: y; /*default div padding in the form e.g. 5px 0 5px 0*/
}
.divForText { /*For Text line only*/
  padding: a;
  margin: b;
}
.divForLabelInput{ /*For Text and Input line */
  padding: c;
  margin: d;
}
.divForInput{ /*For Input line only*/
  padding: e;
  margin: f;
}

HTML:

<div class="divForText">some text</div>
<input ..... />
<div class="divForLabelInput">some label <input ... /></div>
<div class="divForInput"><input ... /></div>

There is a much simpler way in wordpress to create a redirection by using wordpress plugins. So here i found a better way through the plugin Redirection and also you can find other as well on this site Create Url redirect in wordpress through Plugin

Security researchers Jean-Baptiste Bédrune and Jean Sigwald presented how to do this at Hack-in-the-box Amsterdam 2011.

Since then, Apple has released an iOS Security Whitepaper with more details about keys and algorithms, and Charlie Miller et al. have released the iOS Hacker’s Handbook, which covers some of the same ground in a how-to fashion. When iOS 10 first came out there were changes to the backup format which Apple did not publicize at first, but various people reverse-engineered the format changes.

Encrypted backups are great

The great thing about encrypted iPhone backups is that they contain things like WiFi passwords that aren’t in regular unencrypted backups. As discussed in the iOS Security Whitepaper, encrypted backups are considered more “secure,” so Apple considers it ok to include more sensitive information in them.

An important warning: obviously, decrypting your iOS device’s backup removes its encryption. To protect your privacy and security, you should only run these scripts on a machine with full-disk encryption. While it is possible for a security expert to write software that protects keys in memory, e.g. by using functions like VirtualLock() and SecureZeroMemory() among many other things, these Python scripts will store your encryption keys and passwords in strings to be garbage-collected by Python. This means your secret keys and passwords will live in RAM for a while, from whence they will leak into your swap file and onto your disk, where an adversary can recover them. This completely defeats the point of having an encrypted backup.

How to decrypt backups: in theory

The iOS Security Whitepaper explains the fundamental concepts of per-file keys, protection classes, protection class keys, and keybags better than I can. If you’re not already familiar with these, take a few minutes to read the relevant parts.

Now you know that every file in iOS is encrypted with its own random per-file encryption key, belongs to a protection class, and the per-file encryption keys are stored in the filesystem metadata, wrapped in the protection class key.

To decrypt:

1. Decode the keybag stored in the BackupKeyBag entry of Manifest.plist. A high-level overview of this structure is given in the whitepaper. The iPhone Wiki describes the binary format: a 4-byte string type field, a 4-byte big-endian length field, and then the value itself.

   The important values are the PBKDF2 ITERations and SALT, the double protection salt DPSL and iteration count DPIC, and then for each protection CLS, the WPKY wrapped key.

2. Using the backup password derive a 32-byte key using the correct PBKDF2 salt and number of iterations. First use a SHA256 round with DPSL and DPIC, then a SHA1 round with ITER and SALT.

   Unwrap each wrapped key according to RFC 3394.

3. Decrypt the manifest database by pulling the 4-byte protection class and longer key from the ManifestKey in Manifest.plist, and unwrapping it. You now have a SQLite database with all file metadata.

4. For each file of interest, get the class-encrypted per-file encryption key and protection class code by looking in the Files.file database column for a binary plist containing EncryptionKey and ProtectionClass entries. Strip the initial four-byte length tag from EncryptionKey before using.

   Then, derive the final decryption key by unwrapping it with the class key that was unwrapped with the backup password. Then decrypt the file using AES in CBC mode with a zero IV.

How to decrypt backups: in practice

First you’ll need some library dependencies. If you’re on a mac using a homebrew-installed Python 2.7 or 3.7, you can install the dependencies with:

CFLAGS="-I$(brew --prefix)/opt/openssl/include" \
LDFLAGS="-L$(brew --prefix)/opt/openssl/lib" \    
    pip install biplist fastpbkdf2 pycrypto

That code no longer works on backups from phones using the latest iOS, but there are some golang ports that have been kept up to date allowing access to the keychain.

In NoSQL: If Only It Was That Easy, the author writes about MongoDB:

MongoDB is not a key/value store, it’s quite a bit more. It’s definitely not a RDBMS either. I haven’t used MongoDB in production, but I have used it a little building a test app and it is a very cool piece of kit. It seems to be very performant and either has, or will have soon, fault tolerance and auto-sharding (aka it will scale). I think Mongo might be the closest thing to a RDBMS replacement that I’ve seen so far. It won’t work for all data sets and access patterns, but it’s built for your typical CRUD stuff. Storing what is essentially a huge hash, and being able to select on any of those keys, is what most people use a relational database for. If your DB is 3NF and you don’t do any joins (you’re just selecting a bunch of tables and putting all the objects together, AKA what most people do in a web app), MongoDB would probably kick ass for you.

Then, in the conclusion:

The real thing to point out is that if you are being held back from making something super awesome because you can’t choose a database, you are doing it wrong. If you know mysql, just use it. Optimize when you actually need to. Use it like a k/v store, use it like a rdbms, but for god sake, build your killer app! None of this will matter to most apps. Facebook still uses MySQL, a lot. Wikipedia uses MySQL, a lot. FriendFeed uses MySQL, a lot. NoSQL is a great tool, but it’s certainly not going to be your competitive edge, it’s not going to make your app hot, and most of all, your users won’t care about any of this.

What am I going to build my next app on? Probably Postgres. Will I use NoSQL? Maybe. I might also use Hadoop and Hive. I might keep everything in flat files. Maybe I’ll start hacking on Maglev. I’ll use whatever is best for the job. If I need reporting, I won’t be using any NoSQL. If I need caching, I’ll probably use Tokyo Tyrant. If I need ACIDity, I won’t use NoSQL. If I need a ton of counters, I’ll use Redis. If I need transactions, I’ll use Postgres. If I have a ton of a single type of documents, I’ll probably use Mongo. If I need to write 1 billion objects a day, I’d probably use Voldemort. If I need full text search, I’d probably use Solr. If I need full text search of volatile data, I’d probably use Sphinx.

I like this article, I find it very informative, it gives a good overview of the NoSQL landscape and hype. But, and that's the most important part, it really helps to ask yourself the right questions when it comes to choose between RDBMS and NoSQL. Worth the read IMHO.

With Flexbox you can easily horizontally (and vertically) center floated children inside a div.

So if you have simple markup like so:

<div class="wpr">
    <span></span>
    <span></span>
    <span></span>
    <span></span>
    <span></span>
</div>

with CSS:

.wpr
{
    width: 400px;
    height: 100px;
    background: pink;
    padding: 10px 30px;
}

.wpr span
{
    width: 50px;
    height: 50px;
    background: green;
    float: left; /* **children floated left** */
    margin: 0 5px;
}

(This is the (expected - and undesirable) RESULT)

Now add the following rules to the wrapper:

display: flex;
justify-content: center; /* align horizontal */

and the floated children get aligned center (DEMO)

Just for fun, to get vertical alignment as well just add:

align-items: center; /* align vertical */

DEMO

I know this thread has been dead some time, but here is another answer to the old ie8 png background issue.

You can do it in CSS by using IE's proprietary filtering system like this as well:

filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled='true',sizingMethod='scale',src='pathToYourPNG');

DEMO

you will need to use a blank.gif for the 'first' image in your background declaration. This is simply to confuse ie8 and prevent it from using both the filter and the background you have set, and only use the filter. Other browsers support multiple background images and will understand the background declaration and not understand the filter, hence using the background only.

You may also need to play with the sizingMethod in the filter to get it to work the way you want.

Your data class doesn't match the JSON object. Use this instead:

[DataContract]
public class GoogleSearchResults
{
    [DataMember]
    public ResponseData responseData { get; set; }
}

[DataContract]
public class ResponseData
{
    [DataMember]
    public IEnumerable<Results> results { get; set; }
}

[DataContract]
public class Results
{
    [DataMember]
    public string unescapedUrl { get; set; }

    [DataMember]
    public string url { get; set; }

    [DataMember]
    public string visibleUrl { get; set; }

    [DataMember]
    public string cacheUrl { get; set; }

    [DataMember]
    public string title { get; set; }

    [DataMember]
    public string titleNoFormatting { get; set; }

    [DataMember]
    public string content { get; set; }
}

Also, you don't have to instantiate the class to get its type for deserialization:

public static T Deserialise<T>(string json)
{
    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
    {
        var serialiser = new DataContractJsonSerializer(typeof(T));
        return (T)serialiser.ReadObject(ms);
    }
}

We can set the width for ul tag then it will align center.

#header ul {
    display: block;
    margin: 0 auto;
    width: 420px;
    max-width: 100%;
}

Whole system consists from two files, SwipeInterface and ActivitySwipeDetector

SwipeInterface.java

import android.view.View;

public interface SwipeInterface {

    public void bottom2top(View v);

    public void left2right(View v);

    public void right2left(View v);

    public void top2bottom(View v);

}

Detector

import android.util.Log;
import android.view.MotionEvent;
import android.view.View;

public class ActivitySwipeDetector implements View.OnTouchListener {

    static final String logTag = "ActivitySwipeDetector";
    private SwipeInterface activity;
    static final int MIN_DISTANCE = 100;
    private float downX, downY, upX, upY;

    public ActivitySwipeDetector(SwipeInterface activity){
        this.activity = activity;
    }

    public void onRightToLeftSwipe(View v){
        Log.i(logTag, "RightToLeftSwipe!");
        activity.right2left(v);
    }

    public void onLeftToRightSwipe(View v){
        Log.i(logTag, "LeftToRightSwipe!");
        activity.left2right(v);
    }

    public void onTopToBottomSwipe(View v){
        Log.i(logTag, "onTopToBottomSwipe!");
        activity.top2bottom(v);
    }

    public void onBottomToTopSwipe(View v){
        Log.i(logTag, "onBottomToTopSwipe!");
        activity.bottom2top(v);
    }

    public boolean onTouch(View v, MotionEvent event) {
        switch(event.getAction()){
        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;

            // swipe horizontal?
            if(Math.abs(deltaX) > MIN_DISTANCE){
                // left or right
                if(deltaX < 0) { this.onLeftToRightSwipe(v); return true; }
                if(deltaX > 0) { this.onRightToLeftSwipe(v); return true; }
            }
            else {
                Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least " + MIN_DISTANCE);
            }

            // swipe vertical?
            if(Math.abs(deltaY) > MIN_DISTANCE){
                // top or down
                if(deltaY < 0) { this.onTopToBottomSwipe(v); return true; }
                if(deltaY > 0) { this.onBottomToTopSwipe(v); return true; }
            }
            else {
                Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least " + MIN_DISTANCE);
                v.performClick();
            }
        }
        }
        return false;
    }

}

it is used like this:

ActivitySwipeDetector swipe = new ActivitySwipeDetector(this);
LinearLayout swipe_layout = (LinearLayout) findViewById(R.id.swipe_layout);
swipe_layout.setOnTouchListener(swipe);

And in implementing Activity you need to implement methods from SwipeInterface, and you can find out on which View the Swipe Event was called.

@Override
public void left2right(View v) {
    switch(v.getId()){
        case R.id.swipe_layout:
            // do your stuff here
        break;
    }       
}

A php/ajax progress bar can be done. (Checkout the Html_Ajax library in pear). However this requires installing a custom module into php.

Other methods require using an iframe, through which php looks to see how much of the file has been uploaded. However this hidden iframe, may be blocked by some browsers addons because hidden iframes are often used to send malicious data to a users computer.

Your best bet is to use some form of flash progress bar if you do not have control over your server.

If you can not drag and drop your files because you experience the error:

One or more media items failed to import: : The operation couldn’t be completed. (PHPhotosErrorDomain error -1.)

Move your files into the Documents folder and then drag them into the simulator. This will trigger the simulator to ask for permissions to access your files. Having them inside the Downloads folder, will not.

Here's a nicely commented Image Manipulation helper class that you can look at and use. I wrote it as an example of how to perform certain image manipulation tasks in C#. You'll be interested in the ResizeImage function that takes a System.Drawing.Image, the width and the height as the arguments.

Update

A few people have been asking in the comments for samples of how to consume the ImageUtilities class, so here you go.

//resize the image to the specified height and width
using (var resized = ImageUtilities.ResizeImage(image, 50, 100))
{
    //save the resized image as a jpeg with a quality of 90
    ImageUtilities.SaveJpeg(@"C:\myimage.jpeg", resized, 90);
}

Note

Remember that images are disposable, so you need to assign the result of your resize to a using declaration (or you could use a try finally and make sure you call dispose in your finally).

Swift 5:

extension UIImage {
    func cropped(rect: CGRect) -> UIImage? {
        guard let cgImage = cgImage else { return nil }

        UIGraphicsBeginImageContextWithOptions(rect.size, false, 0)
        let context = UIGraphicsGetCurrentContext()

        context?.translateBy(x: 0.0, y: self.size.height)
        context?.scaleBy(x: 1.0, y: -1.0)
        context?.draw(cgImage, in: CGRect(x: rect.minX, y: rect.minY, width: self.size.width, height: self.size.height), byTiling: false)


        let croppedImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return croppedImage
    }
}

There is no way to save directly to a file without a 3rd party tool before Windows 8. Here are my personal favorite non-third party tool solutions.

For Windows 8 and later

+ PrintScreen saves the screenshot into a folder in <user>/Pictures/Screenshots

For Windows 7

In win 7 just use the snipping tool: Most easily accessed via pressing Start, then typing "sni" (enter). or then sni enter

Prior versions of Windows

I use the following keyboard combination to capture, then save using mspaint. After you do it a couple times, it only takes 2-3 seconds:

1. Alt+PrintScreen
2. Win+R ("run")
3. type "mspaint" enter
4. Ctrl-V (paste)
5. Ctrl-S (save)
6. use file dialog
7. Alt-F4 (close mspaint)

In addition, Cropper is great (and open source). It does rectangle capture to file or clipboard, and is of course free.

I checked all the answers around the web and the best one seemed to be: (actually it isn't)

<img src="image.png?cache=none">

at first.

However, if you add cache=none parameter (which is static "none" word), it doesn't effect anything, browser still loads from cache.

Solution to this problem was:

<img src="image.png?nocache=<?php echo time(); ?>">

where you basically add unix timestamp to make the parameter dynamic and no cache, it worked.

However, my problem was a little different: I was loading on the fly generated php chart image, and controlling the page with $_GET parameters. I wanted the image to be read from cache when the URL GET parameter stays the same, and do not cache when the GET parameters change.

To solve this problem, I needed to hash $_GET but since it is array here is the solution:

$chart_hash = md5(implode('-', $_GET));
echo "<img src='/images/mychart.png?hash=$chart_hash'>";

Edit:

Although the above solution works just fine, sometimes you want to serve the cached version UNTIL the file is changed. (with the above solution, it disables the cache for that image completely) So, to serve cached image from browser UNTIL there is a change in the image file use:

echo "<img src='/images/mychart.png?hash=" . filemtime('mychart.png') . "'>";

filemtime() gets file modification time.

As suggested, you can use some 3rd party library, or do it manually (which is not that much work), but the simplest and the most flexible is to perhaps use the built-in functionality in .NET. For more see:

• System.Drawing.Image.PropertyItems Property

• System.Drawing.Imaging.PropertyItem Class

• How to: Read Image Metadata

I say "it’s the most flexible" because .NET does not try to interpret or coalesce the data in any way. For each EXIF you basically get an array of bytes. This may be good or bad depending on how much control you actually want.

Also, I should point out that the property list does not in fact directly correspond to the EXIF values. EXIF itself is stored in multiple tables with overlapping ID’s, but .NET puts everything in one list and redefines ID’s of some items. But as long as you don’t care about the precise EXIF ID’s, you should be fine with the .NET mapping.

Edit: It's possible to do it without loading the full image following this answer: https://stackoverflow.com/a/552642/2097240

Maybe this is not the best way, but it works.

// Here is your path
String p = photosLocation + "whatever.jpg";

// Here is the page address
String pa = Page.Request.Url.AbsoluteUri;

// Take the page name    
String pn = Page.Request.Url.LocalPath;

// Here is the server address    
String sa = pa.Replace(pn, "");

// Take the physical location of the page    
String pl = Page.Request.PhysicalPath;

// Replace the backslash with slash in your path    
pl = pl.Replace("\\", "/");    
p = p.Replace("\\", "/");

// Root path     
String rp = pl.Replace(pn, "");

// Take out same path    
String final = p.Replace(rp, "");

// So your picture's address is    
String path = sa + final;

Edit: Ok, somebody marked as not helpful. Some explanation: take the physical path of the current page, split it into two parts: server and directory (like c:\inetpub\whatever.com\whatever) and page name (like /Whatever.aspx). The image's physical path should contain the server's path, so "substract" them, leaving only the image's path relative to the server's (like: \design\picture.jpg). Replace the backslashes with slashes and append it to the server's url.

Your Test2 class is not a Component, it has a Component which is a difference.

Either you do something like

frame.add(test.getPanel() );

after you introduced a getter for the panel in your class, or you make sure your Test2 class becomes a Component (e.g. by extending a JPanel)

You could use remove(). More information on jQuery remove().

$(this).children("ul").remove();

Note that this will remove all ul elements that are children.

The correct syntax is:

FOR EACH ROW SET NEW.bname = CONCAT( UCASE( LEFT( NEW.bname, 1 ) )
                                   , LCASE( SUBSTRING( NEW.bname, 2 ) ) )

You don't specify a type. The method will only fail (at runtime) if it tries to access attributes that are not defined on the parameters that are passed in.

So this simple function:

def no_op(param1, param2):
    pass

... will not fail no matter what two args are passed in.

However, this function:

def call_quack(param1, param2):
    param1.quack()
    param2.quack()

... will fail at runtime if param1 and param2 do not both have callable attributes named quack.

Did you check the binding is IIS? (inetmgr.exe) It may not be registered to accept all hostnames on 8080.

For example, if you set it up for mysite.com:8080 and hit it at localhost:8080, IIS will get the request but not have a hostname binding to match so it rejects.

Outside of that, you should check the IIS logs (C:\inetpub\logs\wmsvc#) on the server and see if you are seeing your request. Then you'll know if its a problem on your client or on the server itself.

Just as a heads up, the if/then loop is more efficient than the switch for enums. If you have the switch against the raw enum integer, then it's more efficient, but against the variable, if/then is more efficient, at least for Java 5, 6, and 7.

I.e., for some reason (after some performance tests)

if (ordinalValue == 1) {
   ...
} else (ordinalValue == 2 {
   ... 
}

is faster than

switch( myEnum.ordinal() ) {
    case 1:
       ...
       break;
    case 2:
       ...
       break;
}

I see that a few people are doubting me, so I'll post code here that you can run yourself to see the difference, along with output I have from Java 7. The results of the following code with 10 enum values are as follows. Note the key here is the if/then using an integer value comparing against ordinal constants of the enum, vs. the switch with an enum's ordinal value against the raw int ordinal values, vs. a switch with the enum against each enum name. The if/then with an integer value beat out both other switches, although the last switch was a little faster than the first switch, it was not faster than the if/else.

If / else took 23 ms
Switch took 45 ms
Switch 2 took 30 ms
Total matches: 3000000

I have encountered the same error while trying to execute a script file created in windows OS using textpad. so that one can select proper file format like unix/mac etc.. or recreate the script in linux iteself.

First of all, your code works and that's a valid way of creating a function in JavaScript (jQuery aside), but because you are declaring a function inside another function (an anonymous one in this case) "MyBlah" will not be accessible from the global scope.

Here's an example:

$(document).ready( function () {

    var MyBlah = function($blah) { alert($blah);  };

    MyBlah("Hello this works") // Inside the anonymous function we are cool.

 });

MyBlah("Oops") //This throws a JavaScript error (MyBlah is not a function)

This is (sometimes) a desirable behavior since we do not pollute the global namespace, so if your function does not need to be called from other part of your code, this is the way to go.

Declaring it outside the anonymous function places it in the global namespace, and it's accessible from everywhere.

Lastly, the $ at the beginning of the variable name is not needed, and sometimes used as a jQuery convention when the variable is an instance of the jQuery object itself (not necessarily in this case).

Maybe what you need is creating a jQuery plugin, this is very very easy and useful as well since it will allow you to do something like this:

$('div#message').myBlah("hello")

My Jenkins pipeline step shown below failed with the same error.

       steps {
            echo 'Building ...' 
            sh 'sh ./Tools/build.sh'
        }

In my "build.sh" script file "docker run" command output this error when it was executed by Jenkins job. However it was working OK when the script ran in the shell terminal.The error happened because of -t option passed to docker run command that as I know tries to allocate terminal and fails if there is no terminal to allocate.

In my case I have changed the script to pass -t option only if a terminal could be detected. Here is the code after changes :

DOCKER_RUN_OPTIONS="-i --rm"

# Only allocate tty if we detect one
if [ -t 0 ] && [ -t 1 ]; then
    DOCKER_RUN_OPTIONS="$DOCKER_RUN_OPTIONS -t"
fi

docker run $DOCKER_RUN_OPTIONS --name my-container-name  my-image-tag

When you subtract two dates in Oracle, you get the number of days between the two values. So you just have to multiply to get the result in minutes instead:

SELECT (date2 - date1) * 24 * 60 AS minutesBetween
FROM ...

You can use both PHP and javascript. Perform your php codes in the backend and redirect to a php page. On the php page you redirected to add the code below:

<?php if(condition_to_check_for){ ?>

    <script type="text/javascript">
       window.open('url_goes_here', '_blank');
    </script>

<?  } ?>

is it ok? yes, it will compile

is it recommended? no - .c files compile to .obj files, which are linked together after compilation (by the linker) into the executable (or library), so there is no need to include one .c file in another. What you probably want to do instead is to make a .h file that lists the functions/variables available in the other .c file, and include the .h file

You might have to put one or both of:

html { height:100%; }

or

body { height:100%; }

EDIT: Whoops, didn't notice they were floated. You just need to float the container.

had the same problem and just solved it, i used string [variable_Name] =dropdownlist1.SelectedItem.Text;

 .navbar-nav > li > a {padding-top:7px !important; padding-bottom:7px !important;}
.navbar {min-height:32px !important;} 
.navbar-brand{padding-top:7px !important; max-height: 24px;  }
.navbar .navbar-toggle {  margin-top: 0px; margin-bottom: 0px; padding: 8px 9px; }

So here I am, once again, not satisfied with the answer. I was tasked to upgrade JIRA 6.4.x to JIRA Software 7.x and I went to that particular problem with the database and column collation.

In SQL Server, if you do not drop constrains such as primary key or foreign key or even indexes, the script provided above as an answer doesn't work at all. It will however change those without those properties. This is really problematic, because I don't want to manually drop all constrains and create them back. That operation could probably ends up with errors. On the other side, creating a script automating the change could take ages to make.

So I found a way to make the migration simply by using SQL Management Studio. Here's the procedure:

• Rename the database by something else. By example, mine's was "Jira", so I renamed it "JiraTemp".
• Create a new database named "Jira" and make sure to set the right collation. Simply select the page "Options" and change the collation.
• Once created, go back to "JiraTemp", right click it, "Tasks -> Generate Scripts...".
  • Select "Script entire database and all database objects".
  • Select "Save to new query window", then select "Advanced"
  • Change the value of "Script for Server Version" for the desired value
  • Enable "Script Object-Level Permissions", "Script Owner" and "Script Full-Text Indexes"
  • Leave everything else as is or personalize it if you wish.
• Once generated, delete the "CREATE DATABASE" section. Replace "JiraTemp" by "Jira".
• Run the script. The entire database structure and permissions of the database is now replicated to "Jira".
• Before we copy the data, we need to disable all constrains. Execute the following command to do so in the database "Jira": EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"
• Now the data needs to be transferred. To do so, simply right click "JiraTemp", then select "Tasks -> Export Data..."
  • Select as data source and destination the OLE DB Provider for SQL Server.
  • Source database is "JiraTemp"
  • Destination database is "Jira"
  • The server name is technically the same for source and destination (except if you've created the database on another server).
  • Select "Copy data from one or another tables or views"
  • Select all tables except views. Then, when still highlighted, click on "Edit Mappings". Check "Enable identity insert"
  • Click OK, Next, then Finish
• Data transfer can take a while. Once finished, execute the following command to re enable all constrains: exec sp_msforeachtable @command1="print '?'", @command2="ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

Once completed, I've restarted JIRA and my database collation was in order. Hope it helps a lot of people!

The "common knowledge" of programming is that x += y is an equivalent shorthand notation of x = x + y. As long as x and y are of the same type (for example, both are ints), you may consider the two statements equivalent.

However, in Java, x += y is not identical to x = x + y in general.

If x and y are of different types, the behavior of the two statements differs due to the rules of the language. For example, let's have x == 0 (int) and y == 1.1 (double):

    int x = 0;
    x += 1.1;    // just fine; hidden cast, x == 1 after assignment
    x = x + 1.1; // won't compile! 'cannot convert from double to int'

+= performs an implicit cast, whereas for + you need to explicitly cast the second operand, otherwise you'd get a compiler error.

Quote from Joshua Bloch's Java Puzzlers:

(...) compound assignment expressions automatically cast the result of the computation they perform to the type of the variable on their left-hand side. If the type of the result is identical to the type of the variable, the cast has no effect. If, however, the type of the result is wider than that of the variable, the compound assignment operator performs a silent narrowing primitive conversion [JLS 5.1.3].

In C++11 and beyond, you can use the back member function:

char ch = myStr.back();

In C++03, std::string::back is not available due to an oversight, but you can get around this by dereferencing the reverse_iterator you get back from rbegin:

char ch = *myStr.rbegin();

In both cases, be careful to make sure the string actually has at least one character in it! Otherwise, you'll get undefined behavior, which is a Bad Thing.

Hope this helps!

The problem is somewhere else in your code, because this works:

string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));

cout << "* size of the vector: " << strs.size() << endl;    
for (size_t i = 0; i < strs.size(); i++)
    cout << strs[i] << endl;

and testing your approach, which uses a vector iterator also works:

string line("test\ttest2\ttest3");
vector<string> strs;
boost::split(strs,line,boost::is_any_of("\t"));

cout << "* size of the vector: " << strs.size() << endl;
for (vector<string>::iterator it = strs.begin(); it != strs.end(); ++it)
{
    cout << *it << endl;
}

Again, your problem is somewhere else. Maybe what you think is a \t character on the string, isn't. I would fill the code with debugs, starting by monitoring the insertions on the vector to make sure everything is being inserted the way its supposed to be.

Output:

* size of the vector: 3
test
test2
test3

You mean this:

jQuery("input.first").click(function(){
   jQuery("input.second").trigger('click');
   return false;
});

First off, I would generally caution that gathering table statistics in order to do space analysis is a potentially dangerous thing to do. Gathering statistics may change query plans, particularly if the DBA has configured a statistics gathering job that uses non-default parameters that your call is not using, and will cause Oracle to re-parse queries that utilize the table in question which can be a performance hit. If the DBA has intentionally left some tables without statistics (common if your OPTIMIZER_MODE is CHOOSE), gathering statistics can cause Oracle to stop using the rule-based optimizer and start using the cost-based optimizer for a set of queries which can be a major performance headache if it is done unexpectedly in production. If your statistics are accurate, you can query USER_TABLES (or ALL_TABLES or DBA_TABLES) directly without calling GATHER_TABLE_STATS. If your statistics are not accurate, there is probably a reason for that and you don't want to disturb the status quo.

Second, the closest equivalent to the SQL Server sp_spaceused procedure is likely Oracle's DBMS_SPACE package. Tom Kyte has a nice show_space procedure that provides a simple interface to this package and prints out information similar to what sp_spaceused prints out.

  lstResult.Clear();
  foreach (ManagementObject drive in new ManagementObjectSearcher("select * from Win32_DiskDrive where InterfaceType='USB'").Get())
  {
       foreach (ManagementObject partition in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" + drive["DeviceID"] + "'} WHERE AssocClass = Win32_DiskDriveToDiskPartition").Get())
       {
            foreach (ManagementObject disk in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" + partition["DeviceID"] + "'} WHERE AssocClass = Win32_LogicalDiskToPartition").Get())
            {
                  foreach (var item in disk.Properties)
                  {
                       object value = disk.GetPropertyValue(item.Name);
                  }
                  string valor = disk["Name"].ToString();
                  lstResult.Add(valor);
                  }
             }
        }
   }

For an incoming request like /v1/location/1234, as you can imagine it would be difficult for Web API to automatically figure out if the value of the segment corresponding to '1234' is related to appid and not to deviceid.

I think you should change your route template to be like [Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")] and then parse the deiveOrAppid to figure out the type of id.

Also you need to make the segments in the route template itself optional otherwise the segments are considered as required. Note the ? character in this case. For example: [Route("v1/location/{deviceOrAppid?}", Name = "AddNewLocation")]

To do this manually, you'd need something like:

List<string> existing;
if (!myDic.TryGetValue(key, out existing)) {
    existing = new List<string>();
    myDic[key] = existing;
}
// At this point we know that "existing" refers to the relevant list in the 
// dictionary, one way or another.
existing.Add(extraValue);

However, in many cases LINQ can make this trivial using ToLookup. For example, consider a List<Person> which you want to transform into a dictionary of "surname" to "first names for that surname". You could use:

var namesBySurname = people.ToLookup(person => person.Surname,
                                     person => person.FirstName);

The below is my code from reading text file to excel file.

Sub openteatfile()
Dim i As Long, j As Long
Dim filepath As String
filepath = "C:\Users\TarunReddyNuthula\Desktop\sample.ctxt"
ThisWorkbook.Worksheets("Sheet4").Range("Al:L20").ClearContents
Open filepath For Input As #1
i = l
Do Until EOF(1)
Line Input #1, linefromfile
lineitems = Split(linefromfile, "|")
        For j = LBound(lineitems) To UBound(lineitems)
            ThisWorkbook.Worksheets("Sheet4").Cells(i, j + 1).value = lineitems(j)
        Next j
    i = i + 1 
Loop
Close #1
End Sub

What is the current approach to make a custom AuthorizeAttribute

Easy: don't create your own AuthorizeAttribute.

For pure authorization scenarios (like restricting access to specific users only), the recommended approach is to use the new authorization block: https://github.com/aspnet/MusicStore/blob/1c0aeb08bb1ebd846726232226279bbe001782e1/samples/MusicStore/Startup.cs#L84-L92

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<AuthorizationOptions>(options =>
        {
            options.AddPolicy("ManageStore", policy => policy.RequireClaim("Action", "ManageStore"));
        });
    }
}

public class StoreController : Controller
{
    [Authorize(Policy = "ManageStore"), HttpGet]
    public async Task<IActionResult> Manage() { ... }
}

For authentication, it's best handled at the middleware level.

What are you trying to achieve exactly?

pandas as has inbuilt function "get_dummies" to get one hot encoding of that particular column/s.

one line code for one-hot-encoding:

df=pd.concat([df,pd.get_dummies(df['column name'],prefix='column name')],axis=1).drop(['column name'],axis=1)

And another year later, I can tell you there is another nice answer.

If you don't like the way prototyping works in order to extend on objects/classes, take alook at this: https://github.com/haroldiedema/joii

Quick example code of possibilities (and many more):

var Person = Class({

    username: 'John',
    role: 'Employee',

    __construct: function(name, role) {
        this.username = name;
        this.role = role;
    },

    getNameAndRole: function() {
        return this.username + ' - ' + this.role;
    }

});

var Manager = Class({ extends: Person }, {

  __construct: function(name)
  {
      this.super('__construct', name, 'Manager');
  }

});

var m = new Manager('John');
console.log(m.getNameAndRole()); // Prints: "John - Manager"

I think the reason is that in C strings are not primitive types, as tomjen said, think in a string as a char array, so you can not do things like:

switch (char[]) { // ...
switch (int[]) { // ...

You can get a date with that value by using the NSDate(withTimeIntervalSince1970:) initializer:

let date = NSDate(timeIntervalSince1970: 1415637900)

For those who have problem with wrong requestCode in onActivityResult

If you are calling startActivityForResult() from your Fragment, the requestCode is changed by the Activity that owns the Fragment.

If you want to get the correct resultCode in your activity try this:

Change:

startActivityForResult(intent, 1); To:

getActivity().startActivityForResult(intent, 1);

I am using WebAPI 3 and was facing the same issue. The issue has resolve as @Rytis added his solution. And I think in WebAPI 3, we don't need to define method RegisterWebApi.

My change was only in web.config file and is working.

<httpProtocol>
 <customHeaders>
 <add name="Access-Control-Allow-Origin" value="*" />
 <add name="Access-Control-Allow-Methods" value="GET, POST" />
</customHeaders>
</httpProtocol> 

Thanks for you solution @Rytis!

Go to this file in: WampFolder\apps\phpmyadmin[phpmyadmin version]\config.inc.php

Usually wamp is in your main hard drive folder C:\wamp\

You will see something like:

$cfg['Servers'][$i]['user'] = 'YOUR USER NAME IS HERE';
$cfg['Servers'][$i]['password'] = 'AND YOU PASSWORD IS HERE';

Try using the password and username that you have on that file.

Django NewbieMistakes

PROBLEM You're using SQLite3, your DATABASE_NAME is set to the database file's full path, the database file is writeable by Apache, but you still get the above error.

SOLUTION Make sure Apache can also write to the parent directory of the database. SQLite needs to be able to write to this directory.

Make sure each folder of your database file's full path does not start with number, eg. /www/4myweb/db (observed on Windows 2000).

If DATABASE_NAME is set to something like '/Users/yourname/Sites/mydjangoproject/db/db', make sure you've created the 'db' directory first.

Make sure your /tmp directory is world-writable (an unlikely cause as other thing on your system will also not work). ls /tmp -ald should produce drwxrwxrwt ....

Make sure the path to the database specified in settings.py is a full path.

Also make sure the file is present where you expect it to be.

I would like to add another use of Virtual function though it uses the same concept as above stated answers but I guess its worth mentioning.

VIRTUAL DESTRUCTOR

Consider this program below, without declaring Base class destructor as virtual; memory for Cat may not be cleaned up.

class Animal {
    public:
    ~Animal() {
        cout << "Deleting an Animal" << endl;
    }
};
class Cat:public Animal {
    public:
    ~Cat() {
        cout << "Deleting an Animal name Cat" << endl;
    }
};

int main() {
    Animal *a = new Cat();
    delete a;
    return 0;
}

Output:

Deleting an Animal

class Animal {
    public:
    virtual ~Animal() {
        cout << "Deleting an Animal" << endl;
    }
};
class Cat:public Animal {
    public:
    ~Cat(){
        cout << "Deleting an Animal name Cat" << endl;
    }
};

int main() {
    Animal *a = new Cat();
    delete a;
    return 0;
}

Output:

Deleting an Animal name Cat
Deleting an Animal

This answer supposes support for look around! This allowed me to identify all the text between pairs of opening and closing tags. That is all the text between the '>' and the '<'. It works because look around doesn't consume the characters it matches.

(?<=>)([\w\s]+)(?=<\/)

I tested it in https://regex101.com/ using this HTML fragment.

<table>
<tr><td>Cell 1</td><td>Cell 2</td><td>Cell 3</td></tr>
<tr><td>Cell 4</td><td>Cell 5</td><td>Cell 6</td></tr>
</table>

It's a game of three parts: the look behind, the content, and the look ahead.

(?<=>)    # look behind (but don't consume/capture) for a '>'
([\w\s]+) # capture/consume any combination of alpha/numeric/whitespace
(?=<\/)   # look ahead  (but don't consume/capture) for a '</'

I hope that serves as a started for 10. Luck.

If You cannot get Resources object like this in a class which is not an Activity, you have to add getContext() method for getResources() for example

ImageView image = (ImageView) v.findViewById(R.id.item_image);
int id = getContext().getResources().getIdentifier(imageName, "drawable", getContext().getPackageName());
image.setImageResource(id);

While that error message is on the screen (before the rollback begins) go to Control Panel -> Administrative Tools -> Services and see if the service is actually installed. Also check what account it is using to run as. If it's not using Local System, then double and triple check that the account it's using has rights to the program directory where MS SQL installed to.

This is called type methods, and are called with dot syntax, like instance methods. However, you call type methods on the type, not on an instance of that type. Here’s how you call a type method on a class called SomeClass:

use jquery Every time Plugin .using this you can do ajax call for "X" time period

$("#select").everyTime(1000,function(i) {
//ajax call
}

you can also use setInterval

'so many subjective answers to an objective question. "Unobtrusive" JavaScript is superstition like the old rule to never use gotos. Write code in a way that helps you reliably accomplish your goal, not according to someone's trendy religious beliefs.

Anyone who finds:

 <body onload="body_onload();">

to be overly distracting is overly pretentious and doesn't have their priorities straight.

I normally put my JavaScript code in a separate .js file, but I find nothing cumbersome about hooking event handlers in HTML, which is valid HTML by the way.

Assuming your time is called st.etime below and stored in seconds, here is what I use. This handles times where the seconds are greater than 86399 seconds (which is 11:59:59 pm)

case when st.etime > 86399 then to_char(to_date(st.etime - 86400,'sssss'),'HH24:MI:SS') else to_char(to_date(st.etime,'sssss'),'HH24:MI:SS') end readable_time

With SQL 2012 and later, you could use TRY_CAST/TRY_CONVERT to try converting to a numeric type, e.g. TRY_CAST(answer AS float) IS NOT NULL -- note though that this will match scientific notation too (1+E34). (If you use decimal, then scientific notation won't match)

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

None of these answers worked for me.

I had to remove all deployed java web app:

• Windows/Show View/Other...
• Go the the Server folder and select "Servers"
• Right-click on the J2EE Preview at localhost
• Click to Add and Remove... Click Remove all

Then run the project on the server

The Error is gone!

You will have to stop the server before deploying another project because it will not be found by the server. Otherwise you will get a 404 error

Just to note that prefixing the tagName in a selector is slower than just using the id. In your case jQuery will get all the inputs rather than just using the getElementById. Just use $('#textbox')

You can also put DOM elements, like div on top of the canvas that would represent your canvas elements and be positioned the same way.

Now you can attach event listeners to these divs and run the necessary actions.

You haven't stated where you're looking for the element. If it's within the scope of a controller, it is possible, despite the chorus you'll hear about it not being the 'Angular Way'. The chorus is right, but sometimes, in the real world, it's unavoidable. (If you disagree, get in touch—I have a challenge for you.)

If you pass $element into a controller, like you would $scope, you can use its find() function. Note that, in the jQueryLite included in Angular, find() will only locate tags by name, not attribute. However, if you include the full-blown jQuery in your project, all the functionality of find() can be used, including finding by attribute.

So, for this HTML:

<div ng-controller='MyCtrl'>
    <div>
        <div name='foo' class='myElementClass'>this one</div>
    </div>
</div>

This AngularJS code should work:

angular.module('MyClient').controller('MyCtrl', [
    '$scope',
    '$element',
    '$log',
    function ($scope, $element, $log) {

        // Find the element by its class attribute, within your controller's scope
        var myElements = $element.find('.myElementClass');

        // myElements is now an array of jQuery DOM elements

        if (myElements.length == 0) {
            // Not found. Are you sure you've included the full jQuery?
        } else {
            // There should only be one, and it will be element 0
            $log.debug(myElements[0].name); // "foo"
        }

    }
]);

I recently answered a similar question here. Applying the same approach to your problem would yield following solution:

list.sort(
  p2Ord(stringOrd, stringOrd).comap(new F<String, P2<String, String>>() {
    public P2<String, String> f(String s) {
      return p(s.toLowerCase(), s);
    }
  })
);

One more way/syntax to do it is: git log -S "word"
Like this you can search for example git log -S "with whitespaces and stuff @/#ü !"

Go for the simplest and shortest if you can -- DISTINCT seems to be more what you are looking for only because it will give you EXACTLY the answer you need and only that!

I've only used jdom. It's pretty easy.

Go here for documentation and to download it: http://www.jdom.org/

If you have a very very large document then it's better not to read it all into memory, but use a SAX parser which calls your methods as it hits certain tags and attributes. You have to then create a state machine to deal with the incoming calls.

Always google so you can locate the latest package for both NPP and NPP Plugins.

I googled "notepad++ 64bit". Downloaded the free latest version at Notepad++ (64-bit) - Free download and software. Installed notepad++ by double-click on npp.?.?.?.Installer.x64.exe, installed the .exe to default Windows 64bit path which is, "C:\Program Files".

Then, I googled "notepad++ 64 json viewer plug". Knowing SourceForge.Net is a renowned download site, downloaded JSToolNpp [email protected]. I unzipped and copied JSMinNPP.dll to notePad++ root dir.

I loaded my newly installed notepad++ 64bit. I went to Settings and selected [import plug-in]. I pointed to the location of JSMinNPP.dll and clicked open.

I reloaded notepad++, went to PlugIns menu. To format one-line json string to multi-line json doc, I clicked JSTool->JSFormat or reverse multi-line json doc to one-line json string by JSTool->JSMin (json-Minified)!

Integer objects are immutable, so you cannot modify the value once they have been created. You will need to create a new Integer and replace the existing one.

playerID = new Integer(playerID.intValue() + 1);

Field.CurrentPage only works for Filter fields (also called page fields).
If you want to filter a row/column field, you have to cycle through the individual items, like so:

Sub FilterPivotField(Field As PivotField, Value)
    Application.ScreenUpdating = False
    With Field
        If .Orientation = xlPageField Then
            .CurrentPage = Value
        ElseIf .Orientation = xlRowField Or .Orientation = xlColumnField Then
            Dim i As Long
            On Error Resume Next ' Needed to avoid getting errors when manipulating PivotItems that were deleted from the data source.
            ' Set first item to Visible to avoid getting no visible items while working
            .PivotItems(1).Visible = True
            For i = 2 To Field.PivotItems.Count
                If .PivotItems(i).Name = Value Then _
                    .PivotItems(i).Visible = True Else _
                    .PivotItems(i).Visible = False
            Next i
            If .PivotItems(1).Name = Value Then _
                .PivotItems(1).Visible = True Else _
                .PivotItems(1).Visible = False
        End If
    End With
    Application.ScreenUpdating = True
End Sub

Then, you would just call:

FilterPivotField ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode"), "K123223"

Naturally, this gets slower the more there are individual different items in the field. You can also use SourceName instead of Name if that suits your needs better.

If you're an Azure DevOps user looking for both where and how to exclude files and folders, here ya go:

1. Edit your pipeline
2. Make sure you have the "Prepare analysis on SonarQube" task added. You'll need to look elsewhere if you need help configuring this. Suggestion: Use the UI pipeline editor vs the yaml editor if you are missing the manage link. At present, there is no way to convert to UI from yaml. Just recreate the pipeline. If using git, you can delete the yaml from the root of your repo.
3. Under the 'Advanced' section of the "Prepare analysis on SonarQube" task, you can add exclusions. See advice given by others for specific exclusion formats.

Example:

# Additional properties that will be passed to the scanner, 
# Put one key=value per line, example:
# sonar.exclusions=**/*.bin
sonar.exclusions=MyProjectName/MyWebContentFolder/**

Note: If you're not sure on the path, you can go into sonarqube, view your project, look at all or new 'Code Smells' and the path you need is listed above each grouping of issues. You can grab the full path to a file or use wilds like these examples:

• MyProjectName/MyCodeFile.cs
• MyProjectName/**

If you don't have the 'Run Code Analysis' task added, do that and place it somewhere after the 'Build solution **/*.sln' task.

Save and Queue and then check out your sonarqube server to see if the exclusions worked.

Access requires parentheses in the FROM clause for queries which include more than one join. Try it this way ...

FROM
    ((tbl_employee
    INNER JOIN tbl_netpay
    ON tbl_employee.emp_id = tbl_netpay.emp_id)
    INNER JOIN tbl_gross
    ON tbl_employee.emp_id = tbl_gross.emp_ID)
    INNER JOIN tbl_tax
    ON tbl_employee.emp_id = tbl_tax.emp_ID;

If possible, use the Access query designer to set up your joins. The designer will add parentheses as required to keep the db engine happy.

Give the buttons a value attribute and then retrieve the values using this:

$("button").click(function(){
  var value=$(this).attr("value");
});

I have used this before:

$('input[type=checkbox]').prop('checked', false);

seems that .attr and .removeAttr doesn't work for some situations.

edit: Note that in jQuery v1.6 and higher, you should be using .prop('checked', false) instead for greater cross-browser compatibility - see https://api.jquery.com/prop

Comment here: How to reset all checkboxes using jQuery or pure JS?

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs statement to state that the StringBuffer is equivalent to LPSTR.

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Ansi)> _
Public Function GetWindowText(hwnd As IntPtr, <MarshalAs(UnManagedType.LPStr)>lpString As System.Text.StringBuilder, cch As Integer) As Integer
End Function

maybe problem with margin?

width:auto;
padding: 0px;
margin: 0px

A bit shorter, at least:

wanted_keys = ['l', 'm', 'n'] # The keys you want
dict((k, bigdict[k]) for k in wanted_keys if k in bigdict)

You are using the same Cast object for every entry. On each iteration you just changed the same object instead creating a new one.

This code should fix it:

JSONArray jCastArr = jObj.getJSONArray("abridged_cast");
ArrayList<Cast> castList= new ArrayList<Cast>();

for (int i=0; i < jCastArr.length(); i++) {
    Cast person = new Cast();  // create a new object here
    JSONObject jpersonObj = jCastArr.getJSONObject(i);

    person.castId = (String) jpersonObj.getString("id");
    person.castFullName = (String) jpersonObj.getString("name");

    castList.add(person);
}
details.castList = castList;

You can FAKE transitions between gradients, using transitions in the opacity of a few stacked gradients, as described in a few of the answers here:

Try ssh -t -t(or ssh -tt for short) to force pseudo-tty allocation even if stdin isn't a terminal.

See also: Terminating SSH session executed by bash script

From ssh manpage:

-T      Disable pseudo-tty allocation.

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary 
        screen-based programs on a remote machine, which can be very useful,
        e.g. when implementing menu services.  Multiple -t options force tty
        allocation, even if ssh has no local tty.

You need to add the MVC-specific Razor configuration to your web.config. See here: Razor HtmlHelper Extensions (or other namespaces for views) Not Found

Use the MVC 3 upgrade tool to automatically ensure you have the right config values.

This is a sample of execution:

>>> a,b=5,7
>>> x = a > b and 10 or 11
>>> print x

In my opinion, the simplest way to get the amount of selected rows is the following:

The cursor object returns a list with the results when using the fetch commands (fetchall(), fetchone(), fetchmany()). To get the selected rows just print the length of this list. But it just makes sense for fetchall(). ;-)

Example:

print len(cursor.fetchall) 

STEP 1: To check the connected devices, run: flutter devices

STEP 2: If there are no connected devices to see the list of available emulators, run: flutter emulators

STEP 3: To run an emulator, run: flutter emulators --launch <emulator id>

STEP 4: If there is no available emulator, run: flutter emulators --create [--name xyz]

==> FOR ANDROID:

STEP 1: To check the list of emulators, run: emulator -list-avds

STEP 2: Now to launch the emulator, run: emulator -avd avd_name

==> FOR IOS:

STEP 1: open -a simulator

STEP 2: flutter run (In your app directory)

I hope this will solve your problem.

• In C++:

Just use std::vector<char> which keep the (dynamic) size for you. (Bonus, memory management for free).

Or std::array<char, 10> which keep the (static) size.

• In pure C:

Create a structure to keep the info, something like:

typedef struct {
    char* ptr;
    int size;
} my_array;

my_array malloc_array(int size)
{
    my_array res;
    res.ptr = (char*) malloc(size);
    res.size = size;
    return res;
}

void free_array(my_array array)
{
    free(array.ptr);
}

Are you referring to the server side or the client side?

For a client, you would want to adjust the sendTimeout attribute of a binding element. For a service, you would want to adjust the receiveTimeout attribute of a binding elemnent.

<system.serviceModel>
  <bindings>
    <netTcpBinding>
      <binding name="longTimeoutBinding"
        receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <security mode="None"/>
      </binding>
    </netTcpBinding>
  </bindings>

  <services>
    <service name="longTimeoutService"
      behaviorConfiguration="longTimeoutBehavior">
      <endpoint address="net.tcp://localhost/longtimeout/"
        binding="netTcpBinding" bindingConfiguration="longTimeoutBinding" />
    </service>
....

Of course, you have to map your desired endpoint to that particular binding.

R.attr.borderlessButtonStyle doesn't contain shadow.

and the document of button is great.

Also, you can set this style on your custom button, in second constructor.

    public CustomButton(Context context, AttributeSet attrs) {
        this(context, attrs, R.attr.borderlessButtonStyle);
    }

endstring = ''
for s in list:
    endstring += s

You can use either:

1. Behaviour Subject:

BehaviorSubject is a type of subject, a subject is a special type of observable which can act as observable and observer you can subscribe to messages like any other observable and upon subscription, it returns the last value of the subject emitted by the source observable:

Advantage: No Relationship such as parent-child relationship required to pass data between components.

NAV SERVICE

import {Injectable}      from '@angular/core'
import {BehaviorSubject} from 'rxjs/BehaviorSubject';

@Injectable()
export class NavService {
  private navSubject$ = new BehaviorSubject<number>(0);

  constructor() {  }

  // Event New Item Clicked
  navItemClicked(navItem: number) {
    this.navSubject$.next(number);
  }

 // Allowing Observer component to subscribe emitted data only
  getNavItemClicked$() {
   return this.navSubject$.asObservable();
  }
}

NAVIGATION COMPONENT

    </ul>
})
export class Navigation {
  constructor(private navService:NavService) {}
  navItemClicked(item: number) {
    this.navService.navItemClicked(item);
  }
}

OBSERVING COMPONENT

                                      .subscribe(
                                        item => this.selectedNavItem(item)
                                       );

You may use DateDiff and compare by day.

DateDiff(dd,@date1,@date2) > 0

It means @date2 > @date1

For example :

select DateDiff(dd, '01/01/2021 10:20:00', '02/01/2021 10:20:00') 

has the result : 1

Here is the complete process to create a local repo and push the changes to new remote branch

1. Creating local repository:-

   Initially user may have created the local git repository.

   $ git init :- This will make the local folder as Git repository,

2. Link the remote branch:-

   Now challenge is associate the local git repository with remote master branch.

   $ git remote add RepoName RepoURL

   usage: git remote add []

3. Test the Remote

   $ git remote show --->Display the remote name

   $ git remote -v --->Display the remote branches

4. Now Push to remote

   $git add . ----> Add all the files and folder as git staged'

   $git commit -m "Your Commit Message" - - - >Commit the message

   $git push - - - - >Push the changes to the upstream

try using 'acroread' in a simple script like the one above

Go to the "ProjectName" , click on it , and then go the "Build phases" tab , and then click on the "compile sources" , and then click on "+" button , a window will appear , the choose "MyClass.m" file and then click "add" ,

Build the Project and Run it , the problem will surely get solved out

system(cmd);

Take a look at the Java guide on varargs.

You can create a method as shown below. Simply call System.out.printf instead of System.out.println(String.format(....

public static void print(String format, Object... args) {
    System.out.printf(format, args);
}

Alternatively, you can just use a static import if you want to type as little as possible. Then you don't have to create your own method:

import static java.lang.System.out;

out.printf("Numer of apples: %d", 10);

I really like the solution proposed by @Brian Diggs. However, in my case, I create the line plots in a loop rather than giving them explicitly because I do not know apriori how many plots I will have. When I tried to adapt the @Brian's code I faced some problems with handling the colors correctly. Turned out I needed to modify the aesthetic functions. In case someone has the same problem, here is the code that worked for me.

I used the same data frame as @Brian:

data <- structure(list(month = structure(c(1317452400, 1317538800, 1317625200, 1317711600, 
                                       1317798000, 1317884400, 1317970800, 1318057200, 
                                       1318143600, 1318230000, 1318316400, 1318402800, 
                                       1318489200, 1318575600, 1318662000, 1318748400, 
                                       1318834800, 1318921200, 1319007600, 1319094000), 
                                     class = c("POSIXct", "POSIXt"), tzone = ""),
                   TempMax = c(26.58, 27.78, 27.9, 27.44, 30.9, 30.44, 27.57, 25.71, 
                               25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 26.58, 26.18, 
                               25.19, 24.19, 27.65, 23.92), 
                   TempMed = c(22.88, 22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52,
                                 19.71, 20.73, 23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 
                                 20.45, 19.42, 19.97, 19.61), 
                   TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 16.88, 16.82, 
                               14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 16.95, 
                               17.55, 15.21, 14.22, 16.42)), 
              .Names = c("month", "TempMax", "TempMed", "TempMin"), 
              row.names = c(NA, 20L), class = "data.frame")  

In my case, I generate my.cols and my.names dynamically, but I don't want to make things unnecessarily complicated so I give them explicitly here. These three lines make the ordering of the legend and assigning colors easier.

my.cols <- heat.colors(3, alpha=1)
my.names <- c("TempMin", "TempMed", "TempMax")
names(my.cols) <- my.names

And here is the plot:

p <-  ggplot(data, aes(x = month))

for (i in 1:3){
  p <- p + geom_line(aes_(y = as.name(names(data[i+1])), colour = 
colnames(data[i+1])))#as.character(my.names[i])))
}
p + scale_colour_manual("", 
                        breaks = as.character(my.names),
                        values = my.cols)
p

One feature of the DataSet is that if you can call multiple select statements in your stored procedures, the DataSet will have one DataTable for each.

The precise meaning of these terms is going to depend a lot on what language/system/universe you are talking about.

In HTML/XML, an attribute is the part of a tag with an equals sign and a value, and property doesn't mean anything, for example.

So we need more information about what domain you're discussing.

You are populating your dictionaries with references to a single list so when you update it, the update is reflected across all the references. Try a dictionary comprehension instead. See Create a dictionary with list comprehension in Python

d = {k : v for k in blah blah blah}

Pure jQuery.

$.ajax({
  type: "GET",
  url: "https://example.com/file",
  headers: {
    'Authorization': 'Bearer eyJraWQiFUDA.......TZxX1MGDGyg'
  },
  xhrFields: {
    responseType: 'blob'
  },
  success: function (blob) {
    var windowUrl = window.URL || window.webkitURL;
    var url = windowUrl.createObjectURL(blob);
    var anchor = document.createElement('a');
    anchor.href = url;
    anchor.download = 'filename.zip';
    anchor.click();
    anchor.parentNode.removeChild(anchor);
    windowUrl.revokeObjectURL(url);
  },
  error: function (error) {
    console.log(error);
  }
});

Fastest way to do this is using "SELECT INTO" command e.g.

SELECT * INTO #TempTableName
FROM....

This will create a new table, you don't have to create it in advance.

If you've loaded jQuery, you can see if the height of the content is greater than the viewport height. If not, then you can make it that height (or a little less). I ran the following code in WVGA800 mode in the Android emulator, and then ran it on my Samsung Galaxy Tab, and in both cases it hid the addressbar.

$(document).ready(function() {

  if (navigator.userAgent.match(/Android/i)) {
    window.scrollTo(0,0); // reset in case prev not scrolled  
    var nPageH = $(document).height();
    var nViewH = window.outerHeight;
    if (nViewH > nPageH) {
      nViewH -= 250;
      $('BODY').css('height',nViewH + 'px');
    }
    window.scrollTo(0,1);
  }

});

Here is another solution for Crash Log.

Android market has tool named "Crash Collector"

check following link for more information

http://kpbird.blogspot.com/2011/08/android-application-crash-logs.html

Please use the below function if you don't want to round off.

function ConvertToDecimal(num) {
  num = num.toString(); // If it's not already a String
  num = num.slice(0, (num.indexOf(".")) + 3); // With 3 exposing the hundredths place    
alert('M : ' + Number(num)); // If you need it back as a Number     
}

With

with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.

Example:

User > hasMany > Post

$users = User::with('posts')->get();
foreach($users as $user){
    $users->posts; // posts is already loaded and no additional DB query is run
}

Has

has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.

Example:

User > hasMany > Post

$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection

WhereHas

whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.

Example:

User > hasMany > Post

$users = User::whereHas('posts', function($q){
    $q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned

RewriteCond %{HTTP:X-Forwarded-Proto} =https

You have to wrap the word in a span to accomplish this.

Your repo is yours, what goes on in it is entirely your business until you push or (allow a) fetch or clone. When you deleted your windows repo -- that folder didn't represent your local repo, it was your actual local repo, you deleted everything done in it that was never pushed, fetched or cloned.

edit: Ah, okay, I think I see what's going on here: you pushed to your linux repo but it's not bare and you never worked in it.

Instead of git log, do git log --all. Or git checkoutsome-branch-name.

Then try cloning the repo locally, on your linux box; I bet it works. What are you using to serve your repo on linux? Try cd'ing into its .git directory and git daemon --base-path=. --export-all, if that just sits there then go to your windows box and try git clone git://your.linux.box.ip, if the daemon complains it can't bind add --port=54345 to the daemon invoke and :54345 to the clone url.

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

You are binding the click event to anchors with an href attribute with value sign_new.

Either bind anchors with class sign_new or bind anchors with href value #sign_up. I would prefer the former.

The MDN Documentation is very eloquent and features examples.

Building on Matteo Furlans design, when he said "most dynamic array implementations work by starting off with an array of some (small) default size, then whenever you run out of space when adding a new element, double the size of the array". The difference in the "work in progress" below is that it doesn't double in size, it aims at using only what is required.

There is %history magic for printing and saving the input history (and optionally the output).

To store your current session to a file named my_history.py:

>>> %hist -f my_history.py

History IPython stores both the commands you enter, and the results it produces. You can easily go through previous commands with the up- and down-arrow keys, or access your history in more sophisticated ways.

You can use the %history magic function to examine past input and output. Input history from previous sessions is saved in a database, and IPython can be configured to save output history.

Several other magic functions can use your input history, including %edit, %rerun, %recall, %macro, %save and %pastebin. You can use a standard format to refer to lines:

%pastebin 3 18-20 ~1/1-5

This will take line 3 and lines 18 to 20 from the current session, and lines 1-5 from the previous session.

See %history? for the Docstring and more examples.

Also, be sure to explore the capabilities of %store magic for lightweight persistence of variables in IPython.

Stores variables, aliases and macros in IPython’s database.

d = {'a': 1, 'b': 2}
%store d  # stores the variable
del d

%store -r d  # Refresh the variable from IPython's database.
>>> d
{'a': 1, 'b': 2}

To autorestore stored variables on startup, specifyc.StoreMagic.autorestore = True in ipython_config.py.

Firstly, in general:

If these .h files are indeed typical C-style header files (as opposed to being something completely different that just happens to be named with .h extension), then no, there's no reason to "compile" these header files independently. Header files are intended to be included into implementation files, not fed to the compiler as independent translation units.

Since a typical header file usually contains only declarations that can be safely repeated in each translation unit, it is perfectly expected that "compiling" a header file will have no harmful consequences. But at the same time it will not achieve anything useful.

Basically, compiling hello.h as a standalone translation unit equivalent to creating a degenerate dummy.c file consisting only of #include "hello.h" directive, and feeding that dummy.c file to the compiler. It will compile, but it will serve no meaningful purpose.

Secondly, specifically for GCC:

Many compilers will treat files differently depending on the file name extension. GCC has special treatment for files with .h extension when they are supplied to the compiler as command-line arguments. Instead of treating it as a regular translation unit, GCC creates a precompiled header file for that .h file.

You can read about it here: http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html

So, this is the reason you might see .h files being fed directly to GCC.

next:

select * from foo where id = (select min(id) from foo where id > 4)

previous:

select * from foo where id = (select max(id) from foo where id < 4)

You can use online Minify, it removes these invisible characters efficiently but also changes your code. So be careful.

I had issues with latest version of yarn 1.15.1-1

I've fixed it by downgrading to lower version sudo apt-get install yarn=1.12.3-1

From the 1.1.x documentation, you can enable debug mode by exporting an environment variable to your shell prompt:

export FLASK_APP=/daemon/api/views.py  # path to app
export FLASK_DEBUG=1
python -m flask run --host=0.0.0.0

Using the return codes from net start and net stop seems like the best method to me. Try a look at this: Net Start return codes.

You save some bytes by avoiding the .attr altogether by passing the properties to the jQuery constructor:

var img = $('<img />',
             { id: 'Myid',
               src: 'MySrc.gif', 
               width: 300
             })
              .appendTo($('#YourDiv'));

You could use this jQuery plugin: https://github.com/mathiasbynens/jquery-placeholder

But your link seems to be also a good solution.

Change:

struct timeval, tvalBefore, tvalAfter; /* Looks like an attempt to
                                          delcare a variable with
                                          no name. */

to:

struct timeval tvalBefore, tvalAfter;

It is less likely (IMO) to make this mistake if there is a single declaration per line:

struct timeval tvalBefore;
struct timeval tvalAfter;

It becomes more error prone when declaring pointers to types on a single line:

struct timeval* tvalBefore, tvalAfter;

tvalBefore is a struct timeval* but tvalAfter is a struct timeval.

So you didn't say you wanted the application to quit or exit abruptly, so as another option, perhaps just have the response loop end out elegantly. (I am assuming you have a while loop waiting for user instructions. This is some code from a project I just wrote today.

See .offset() here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset() and .position() confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop() and .scrollLeft() values to account for the scrolled position.

Here's an excerpt from the doc:

The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.

To combine these:

var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft(); 

You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

You'll need AJAX if you want to update a part of your page without reloading the entire page.

main cshtml view

<div id="refTable">
     <!-- partial view content will be inserted here -->
</div>

@Html.TextBox("yearSelect3", Convert.ToDateTime(tempItem3.Holiday_date).Year.ToString());
<button id="pY">PrevY</button>

<script>
    $(document).ready(function() {
        $("#pY").on("click", function() {
            var val = $('#yearSelect3').val();
            $.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });
        });
    });
</script>

You'll need to add the fields I have omitted. I've used a <button> instead of submit buttons because you don't have a form (I don't see one in your markup) and you just need them to trigger javascript on the client side.

The HolidayPartialView gets rendered into html and the jquery done callback inserts that html fragment into the refTable div.

HolidayController Update action

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

This controller action takes the year parameter and returns a list of dates using a strongly-typed view model instead of the ViewBag.

view model

public class HolidayViewModel
{
    IEnumerable<DateTime> Dates { get; set; }
}

HolidayPartialView.csthml

@model Your.Namespace.HolidayViewModel;

<table class="tblHoliday">
    @foreach(var date in Model.Dates)
    {
        <tr><td>@date.ToString("MM/dd/yyyy")</td></tr>
    }
</table>

This is the stuff that gets inserted into your div.

Most of the answers are working fine. We can also check the request header

request()->header('Accept')=='application/json'

In Spring you can escape the html from JSP pages generated by <form> tags. This closes off a lot avenues for XSS attacks, and can be done automatically in three ways:

For the entire application in the web.xml file:

<context-param>
    <param-name>defaultHtmlEscape</param-name>
    <param-value>true</param-value>
</context-param>

For all forms on a given page in the file itself:

<spring:htmlEscape defaultHtmlEscape="true" /> 

For each form:

<form:input path="someFormField" htmlEscape="true" /> 

JavaService is LGPL. It is very easy and stable. Highly recommended.

This is an issue in the Chrome family and has been there forever.

A bug has been raised https://bugs.chromium.org/p/chromium/issues/detail?id=904208

It can be shown here: https://codepen.io/anon/pen/Jedvwj as soon as you add a border to anything button-like (say role="button" has been added to a tag for example) Chrome messes up and sets the focus state when you click with your mouse. You should see that outline only on keyboard tab-press.

I highly recommend using this fix: https://github.com/wicg/focus-visible.

Just do the following

npm install --save focus-visible

Add the script to your html:

<script src="/node_modules/focus-visible/dist/focus-visible.min.js"></script>

or import into your main entry file if using webpack or something similar:

import 'focus-visible/dist/focus-visible.min';

then put this in your css file:

// hide the focus indicator if element receives focus via mouse, but show on keyboard focus (on tab).
.js-focus-visible :focus:not(.focus-visible) {
  outline: none;
}

// Define a strong focus indicator for keyboard focus.
// If you skip this then the browser's default focus indicator will display instead
// ideally use outline property for those users using windows high contrast mode
.js-focus-visible .focus-visible {
  outline: magenta auto 5px;
}

You can just set:

button:focus {outline:0;}

but if you have a large number of users, you're disadvantaging those who cannot use mice or those who just want to use their keyboard for speed.

            int CountNumberOfMonths() => (date2.Month - date1.Month) + 12 * (date2.Year - date1.Year);

            var numberOfMonths = CountNumberOfMonths();

            Console.WriteLine("Number of months between {0} and {1}: {2} months.", date1.ToString(), date2.ToString(), numberOfMonths.ToString());

As stated by a few others, this is a linking error. The section of code where this function is being called doesn't know what this function is. It either needs to be declared in a header file an defined in its own source file, or defined or declared in the same source file, above where it's being called.

Edit: In older versions of C, C89/C90, function declarations weren't actually required. So, you could just add the definition anywhere in the file in which you're using the function, even after the call and the compiler would infer the declaration. For example,

int main()
{
  int a = func();
}

int func()
{
   return 1;
}

However, this isn't good practice today and most languages, C++ for example, won't allow it. One way to get away with defining the function in the same source file in which you're using it, is to declare it at the beginning of the file. So, the previous example would look like this instead.

int func();

int main()
{
   int a = func();
}

int func()
{
  return 1;
}

I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.

To match multiple occurrences, one might do something like this:

iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]

This would return a list of the two indices for the original string.

If you are using Anaconda's Python distribution,

For method decorator declaration with configuration "noImplicitAny": true, you can specify type of this variable explicitly depends on @tony19's answer

function logParameter(this:any, target: Object, propertyName: string) {
  //...
}

I need to do the same thing. I ended up with something similar to Kman

       static void ExcelToCSVCoversion(string sourceFile,  string targetFile)
    {
        Application rawData = new Application();

        try
        {
            Workbook workbook = rawData.Workbooks.Open(sourceFile);
            Worksheet ws = (Worksheet) workbook.Sheets[1];
            ws.SaveAs(targetFile, XlFileFormat.xlCSV);
            Marshal.ReleaseComObject(ws);
        }

        finally
        {
            rawData.DisplayAlerts = false;
            rawData.Quit();
            Marshal.ReleaseComObject(rawData);
        }


        Console.WriteLine();
        Console.WriteLine($"The excel file {sourceFile} has been converted into {targetFile} (CSV format).");
        Console.WriteLine();
    }

If there are multiple sheets this is lost in the conversion but you could loop over the number of sheets and save each one as csv.

You can use stristr() or strpos(). Both return false if nothing is found.

This is what I use to control headers/caching, I'm not an Apache pro, so let me know if there is room for improvement, but I know that this has been working well on all of my sites for some time now.

Mod_expires

http://httpd.apache.org/docs/2.2/mod/mod_expires.html

This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.

These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.

# BEGIN Expires
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
</ifModule>
# END Expires

Mod_headers

http://httpd.apache.org/docs/2.2/mod/mod_headers.html

This module provides directives to control and modify HTTP request and response headers. Headers can be merged, replaced or removed.

# BEGIN Caching
<ifModule mod_headers.c>
<filesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">

</ifModule>
# END Caching

Basing on Ilya's data, I wrote a Vanilla JS library for supporting modifier keys on Mac: https://github.com/MichaelZelensky/jsLibraries/blob/master/macKeys.js

Just use it like this, e.g.:

document.onclick = function (event) {
  if (event.shiftKey || macKeys.shiftKey) {
    //do something interesting
  }
}

Tested on Chrome, Safari, Firefox, Opera on Mac. Please check if it works for you.

The easiest one e.g. if you have a string array declared like this string[] myStringArray = new string[];

Console.WriteLine("Array : ");
Console.WriteLine("[{0}]", string.Join(", ", myStringArray));

Another example to output date and time using zero as a fill character on instances of single digit values: 2017-06-04 18:13:02

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main()
{
    time_t t = time(0);   // Get time now
    struct tm * now = localtime(&t);
    cout.fill('0');
    cout << (now->tm_year + 1900) << '-'
        << setw(2) << (now->tm_mon + 1) << '-'
        << setw(2) << now->tm_mday << ' '
        << setw(2) << now->tm_hour << ':'
        << setw(2) << now->tm_min << ':'
        << setw(2) << now->tm_sec
        << endl;
    return 0;
}

in addition: for those who have a empty POST variable, don't use this:

name="[levels][level][]"

rather use this (as it is already here in this example):

name="levels[level][]"

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

     //>=, not <=
    if (scroll >= 500) {
        //clearHeader, not clearheader - caps H
        $(".clearHeader").addClass("darkHeader");
    }
}); //missing );

Fiddle

Also, by removing the clearHeader class, you're removing the position:fixed; from the element as well as the ability of re-selecting it through the $(".clearHeader") selector. I'd suggest not removing that class and adding a new CSS class on top of it for styling purposes.

And if you want to "reset" the class addition when the users scrolls back up:

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

    if (scroll >= 500) {
        $(".clearHeader").addClass("darkHeader");
    } else {
        $(".clearHeader").removeClass("darkHeader");
    }
});

Fiddle

edit: Here's version caching the header selector - better performance as it won't query the DOM every time you scroll and you can safely remove/add any class to the header element without losing the reference:

$(function() {
    //caches a jQuery object containing the header element
    var header = $(".clearHeader");
    $(window).scroll(function() {
        var scroll = $(window).scrollTop();

        if (scroll >= 500) {
            header.removeClass('clearHeader').addClass("darkHeader");
        } else {
            header.removeClass("darkHeader").addClass('clearHeader');
        }
    });
});

Fiddle

I use this script to check if a file exists (also it handles the cross origin issue):

$.ajax(url, {
       method: 'GET',
       dataType: 'jsonp'
         })
   .done(function(response) { 
        // exists code 
    }).fail(function(response) { 
        // doesnt exist
    })

Note that the following syntax error is thrown when the file being checked doesn't contain JSON.

Uncaught SyntaxError: Unexpected token <

aapt command is located on Android\SDK\build-tools\version. If you need more info about what is appt command (Android Asset Packaging Tool) read this https://stackoverflow.com/a/28234956/812915

The dump sub-command of aapt is used to display the values of individual elements or parts of a package:

aapt dump badging <path-to-apk>

If you want see only the line with package: name info, use findstr

aapt dump badging <path-to-apk> | findstr -n "package: name" | findstr "1:"

Hope it help other windows user!

replace , with .

The simplest way is to generate a random nuber between 0-1 then strech it by multiplying, and shifting it.
So yo would multiply by (x-y) so the result is in the range of 0 to x-y,
Then add x and you get the random number between x and y.

To get a five multiplier use rounding. If this is unclear let me know and I'll add code snippets.

to overcome this kind of problem follow the steps below:

• open command prompt.
• c:\Users\CGITS_04> netstat -o -n -a | findstr 0.0:80
• then you can see a list of process that is currently using port 80.
• open task manager->search the process-> select and end process.
• Now open eclipse and start tomcat.
• happy coding!

Obviously there are a number of possible causes and the previous answers document them well, but here's how I solved this for in one particular case:

A student of mine had this problem and I nearly tore my hair out trying to figure it out. It turned out that the file didn't exist, even though it looked like it did. The problem was that Windows 7 was configured to "Hide file extensions for known file types." This means that if file appears to have the name "data.txt" its actual filename is "data.txt.txt".

Hope this helps others save themselves some hair.

You can pass plt.scatter a c argument which will allow you to select the colors. The code below defines a colors dictionary to map your diamond colors to the plotting colors.

import matplotlib.pyplot as plt
import pandas as pd

carat = [5, 10, 20, 30, 5, 10, 20, 30, 5, 10, 20, 30]
price = [100, 100, 200, 200, 300, 300, 400, 400, 500, 500, 600, 600]
color =['D', 'D', 'D', 'E', 'E', 'E', 'F', 'F', 'F', 'G', 'G', 'G',]

df = pd.DataFrame(dict(carat=carat, price=price, color=color))

fig, ax = plt.subplots()

colors = {'D':'red', 'E':'blue', 'F':'green', 'G':'black'}

ax.scatter(df['carat'], df['price'], c=df['color'].apply(lambda x: colors[x]))

plt.show()

df['color'].apply(lambda x: colors[x]) effectively maps the colours from "diamond" to "plotting".

(Forgive me for not putting another example image up, I think 2 is enough :P)

With seaborn

You can use seaborn which is a wrapper around matplotlib that makes it look prettier by default (rather opinion-based, I know :P) but also adds some plotting functions.

For this you could use seaborn.lmplot with fit_reg=False (which prevents it from automatically doing some regression).

The code below uses an example dataset. By selecting hue='color' you tell seaborn to split your dataframe up based on your colours and then plot each one.

import matplotlib.pyplot as plt
import seaborn as sns

import pandas as pd

carat = [5, 10, 20, 30, 5, 10, 20, 30, 5, 10, 20, 30]
price = [100, 100, 200, 200, 300, 300, 400, 400, 500, 500, 600, 600]
color =['D', 'D', 'D', 'E', 'E', 'E', 'F', 'F', 'F', 'G', 'G', 'G',]

df = pd.DataFrame(dict(carat=carat, price=price, color=color))

sns.lmplot('carat', 'price', data=df, hue='color', fit_reg=False)

plt.show()

Without seaborn using pandas.groupby

If you don't want to use seaborn then you can use pandas.groupby to get the colors alone and then plot them using just matplotlib, but you'll have to manually assign colors as you go, I've added an example below:

fig, ax = plt.subplots()

colors = {'D':'red', 'E':'blue', 'F':'green', 'G':'black'}

grouped = df.groupby('color')
for key, group in grouped:
    group.plot(ax=ax, kind='scatter', x='carat', y='price', label=key, color=colors[key])

plt.show()

This code assumes the same DataFrame as above and then groups it based on color. It then iterates over these groups, plotting for each one. To select a color I've created a colors dictionary which can map the diamond color (for instance D) to a real color (for instance red).

Does this work? Untested but should get the point across.

UPDATE FUNCTIONS
SET Func_TaxRef = 
(
  SELECT Min(TAX.Tax_Code) AS MinOfTax_Code
  FROM TAX, FUNCTIONS F1
  WHERE F1.Func_Pure <= [Tax_ToPrice]
    AND F1.Func_Year=[Tax_Year]
    AND F1.Func_ID = FUNCTIONS.Func_ID
  GROUP BY F1.Func_ID;
)

Basically for each row in FUNCTIONS, the subquery determines the minimum current tax code and sets FUNCTIONS.Func_TaxRef to that value. This is assuming that FUNCTIONS.Func_ID is a Primary or Unique key.

I have a very simple solution. I use IntelliJ for development, so the details vary but the idea should apply across all IDE's.

I pick to root of my source tree, right-click and select to do "replace". I then choose to replace all "Log." with "//Log.". This removes all log statements. To put them back later I repeat the same replace but this time as replace all "//Log." with "Log.".

Works just great for me. Just remember to set the replace as case sensitive to avoid accidents such as "Dialog.". For added assurance you can also do the first step with " Log." as the string to search.

Brilliant.

You have to follow Pawel's steps and then go to the key that is "Cookie". This will open a submenu with all the cookies and it specifies their name, value, domain, etc...

Respectively the values are: Key, Value, Expiration Date, Domain, Path.

This shows all the keys for this domain.

So again to get there:

1. Go to Network.
2. Capture Traffic, green triangle.
3. Go to Details.
4. Go to the "Cookie" key that has a gibberish value. (_utmc=xxxxx;something=ajksdhfa) etc...

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

Use the CellMouseDown event on the DataGridView. From the event handler arguments you can determine which cell was clicked. Using the PointToClient() method on the DataGridView you can determine the relative position of the pointer to the DataGridView, so you can pop up the menu in the correct location.

(The DataGridViewCellMouseEvent parameter just gives you the X and Y relative to the cell you clicked, which isn't as easy to use to pop up the context menu.)

This is the code I used to get the mouse position, then adjust for the position of the DataGridView:

var relativeMousePosition = DataGridView1.PointToClient(Cursor.Position);
this.ContextMenuStrip1.Show(DataGridView1, relativeMousePosition);

The entire event handler looks like this:

private void DataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    // Ignore if a column or row header is clicked
    if (e.RowIndex != -1 && e.ColumnIndex != -1)
    {
        if (e.Button == MouseButtons.Right)
        {
            DataGridViewCell clickedCell = (sender as DataGridView).Rows[e.RowIndex].Cells[e.ColumnIndex];

            // Here you can do whatever you want with the cell
            this.DataGridView1.CurrentCell = clickedCell;  // Select the clicked cell, for instance

            // Get mouse position relative to the vehicles grid
            var relativeMousePosition = DataGridView1.PointToClient(Cursor.Position);

            // Show the context menu
            this.ContextMenuStrip1.Show(DataGridView1, relativeMousePosition);
        }
    }
}

Yes, but you'll need to be using .NET 3.5 and C# 4.0 to get this functionality.

This MSDN page has more information.

For those who would like to listen to the actual inner height and vertical scroll of the window while the Chrome mobile browser is transition the URL bar from shown to hidden and vice versa, the only solution that I found is to set an interval function, and measure the discrepancy of the window.innerHeight with its previous value.

This introduces this code:

var innerHeight = window.innerHeight;_x000D_
window.setInterval(function ()_x000D_
{_x000D_
  var newInnerHeight = window.innerHeight;_x000D_
  if (newInnerHeight !== innerHeight)_x000D_
  {_x000D_
    var newScrollY = window.scrollY + newInnerHeight - innerHeight;_x000D_
    // ... do whatever you want with this new scrollY_x000D_
    innerHeight = newInnerHeight;_x000D_
  }_x000D_
}, 1000 / 60);

I hope that this will be handy. Does anyone knows a better solution?

The short answer

Use the source command.

An example using source

For example:

config.sh

#!/usr/bin/env bash
production="liveschool_joe"
playschool="playschool_joe"
echo $playschool

script.sh

#!/usr/bin/env bash
source config.sh
echo $production

Note that the output from sh ./script.sh in this example is:

~$ sh ./script.sh 
playschool_joe
liveschool_joe

This is because the source command actually runs the program. Everything in config.sh is executed.

Another way

You could use the built-in export command and getting and setting "environment variables" can also accomplish this.

Running export and echo $ENV should be all you need to know about accessing variables. Accessing environment variables is done the same way as a local variable.

To set them, say:

export variable=value

at the command line. All scripts will be able to access this value.

since my post above, I have moved to a Generic Factory Class

Usage

 services.AddFactory<IProcessor, string>()
         .Add<ProcessorA>("A")
         .Add<ProcessorB>("B");

 public MyClass(IFactory<IProcessor, string> processorFactory)
 {
       var x = "A"; //some runtime variable to select which object to create
       var processor = processorFactory.Create(x);
 }

Implementation

public class FactoryBuilder<I, P> where I : class
{
    private readonly IServiceCollection _services;
    private readonly FactoryTypes<I, P> _factoryTypes;
    public FactoryBuilder(IServiceCollection services)
    {
        _services = services;
        _factoryTypes = new FactoryTypes<I, P>();
    }
    public FactoryBuilder<I, P> Add<T>(P p)
        where T : class, I
    {
        _factoryTypes.ServiceList.Add(p, typeof(T));

        _services.AddSingleton(_factoryTypes);
        _services.AddTransient<T>();
        return this;
    }
}
public class FactoryTypes<I, P> where I : class
{
    public Dictionary<P, Type> ServiceList { get; set; } = new Dictionary<P, Type>();
}

public interface IFactory<I, P>
{
    I Create(P p);
}

public class Factory<I, P> : IFactory<I, P> where I : class
{
    private readonly IServiceProvider _serviceProvider;
    private readonly FactoryTypes<I, P> _factoryTypes;
    public Factory(IServiceProvider serviceProvider, FactoryTypes<I, P> factoryTypes)
    {
        _serviceProvider = serviceProvider;
        _factoryTypes = factoryTypes;
    }

    public I Create(P p)
    {
        return (I)_serviceProvider.GetService(_factoryTypes.ServiceList[p]);
    }
}

Extension

namespace Microsoft.Extensions.DependencyInjection
{
    public static class DependencyExtensions
    {
        public static FactoryBuilder<I, P> AddFactory<I, P>(this IServiceCollection services)
            where I : class
        {
            services.AddTransient<IFactory<I, P>, Factory<I, P>>();
            return new FactoryBuilder<I, P>(services);
        }
    }
}

I found some way to perform in on dictionary contain my custom class methods

foreach (var item in this.Values.Where(p => p.IsActive == false))
            item.Refresh();

Where 'this' derived from : Dictionary<string, MyCustomClass>

class MyCustomClass 
{
   public void Refresh(){}
}

For the impatient:

UPDATE target AS t
INNER JOIN (
  SELECT s.id, COUNT(*) AS count
  FROM source_grouped AS s
  -- WHERE s.custom_condition IS (true)
  GROUP BY s.id
) AS aggregate ON aggregate.id = t.id
SET t.count = aggregate.count

That's @mellamokb's answer, as above, reduced to the max.

A lot of answers have been given, but id like to add to them.

If you need the week to display as a year/week style (ex. 1953 - week 53 of 2019, 2001 - week 1 of 2020 etc.), you can do this:

import datetime

year = datetime.datetime.now()
week_num = datetime.date(year.year, year.month, year.day).strftime("%V")
long_week_num = str(year.year)[0:2] + str(week_num)

It will take the current year and week, and long_week_num in the day of writing this will be:

>>> 2006

BinaryFormatter may produce invalid output in some specific cases. For example it will omit unpaired surrogate characters. It may also have problems with values of interface types. Read this documentation page including community content.

If you find your error to be persistent you may want to consider using XML serializer like DataContractSerializer or XmlSerializer.

same issue on windows10 and above solutions are not working for me.

use a emulator console tool like cygwin and then do it the default linux way:

export http_proxy=<proxy>
export https_proxy=<proxy>
pip install <package>

and things are working fine.

Try this:

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class Main {

    public static void main(String[] argv) throws Exception {

    JTextField textField = new JTextField();

    textField.addKeyListener(new Keychecker());

    JFrame jframe = new JFrame();

    jframe.add(textField);

    jframe.setSize(400, 350);

    jframe.setVisible(true);

}

class Keychecker extends KeyAdapter {

    @Override
    public void keyPressed(KeyEvent event) {

        char ch = event.getKeyChar();

        System.out.println(event.getKeyChar());

    }

}

You can create a new file, setenv.sh (or setenv.bat) inside tomcats bin directory and add following line there

export CLASSPATH=$CLASSPATH:/XX/xx/PATH_TO_DIR

This may be the fastest way:

>> array('B', map(ord,a)).tostring()
'abcd'

It depends on the database to which you're trying to connect, the method by which you created the connection, and the version of Excel that you're using. (Also, most probably, the version of the relevant ODBC driver on your computer.)

The following examples are using SQL Server 2008 and Excel 2007, both on my local machine.

When I used the Data Connection Wizard (on the Data tab of the ribbon, in the Get External Data section, under From Other Sources), I saw the same thing that you did: the Parameters button was disabled, and adding a parameter to the query, something like select field from table where field2 = ?, caused Excel to complain that the value for the parameter had not been specified, and the changes were not saved.

When I used Microsoft Query (same place as the Data Connection Wizard), I was able to create parameters, specify a display name for them, and enter values each time the query was run. Bringing up the Connection Properties for that connection, the Parameters... button is enabled, and the parameters can be modified and used as I think you want.

I was also able to do this with an Access database. It seems reasonable that Microsoft Query could be used to create parameterized queries hitting other types of databases, but I can't easily test that right now.

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

• Multi-stage builds
• COPY syntax

Sometimes, I try to use anonymous function to achieve defining and assigning happen at the same line. like below:

a, b = 4, 8

c := func() int {
    if a >b {
      return a
    } 
    return b
  } ()

https://play.golang.org/p/rMjqytMYeQ0

You can just use toggleClass() to track state. Then you check if button element has the class, like this:

$("button.toggler").click( function() {
    $me = $(this);
    $me.toggleClass('off');
    if($me.is(".off")){
        alert('hi');
    }else {
        alert('bye');
    }
});

And I use the button element for buttons for semantic reasons.

<button class="toggler">Toggle me</button>

Alternatively,

1) Without touching System.Reflection namespace,

GETNAME(new { myInput });

public static string GETNAME<T>(T myInput) where T : class
{
    if (myInput == null)
        return string.Empty;

    return myInput.ToString().TrimStart('{').TrimEnd('}').Split('=')[0].Trim();
}

2) The below one can be faster though (from my tests)

GETNAME(new { variable });
public static string GETNAME<T>(T myInput) where T : class
{
    if (myInput == null)
        return string.Empty;

    return typeof(T).GetProperties()[0].Name;
}

You can also extend this for properties of objects (may be with extension methods):

new { myClass.MyProperty1 }.GETNAME();

You can cache property values to improve performance further as property names don't change during runtime.

The Expression approach is going to be slower for my taste. To get parameter name and value together in one go see this answer of mine

Your local web server is running different code than what you're actually working on. Ensure you have stopped debugging, stop your local web server, clean and rebuild as Peter suggested, double-check your global.asax and global.asax.cs, and try again.

If this doesn't work and you are using local IIS, try removing the site in IIS Manager and recreating it manually.

To trigger the function with click or touch, you could change this:

$(document).click( function () {

To this:

$(document).on('click touchstart', function () {

Or this:

$(document).on('click touch', function () {

The touchstart event fires as soon as an element is touched, the touch event is more like a "tap", i.e. a single contact on the surface. You should really try each of these to see what works best for you. On some devices, touch can be a little harder to trigger (which may be a good or bad thing - it prevents a drag being counted, but an accidental small drag may cause it to not be fired).

Add the css for .card

.card {
        margin: 0 auto; /* Added */
        float: none; /* Added */
        margin-bottom: 10px; /* Added */
}

here is the pen

UPDATE: You can use the class .mx-auto available in bootstrap 4 to center cards.

Try using Response.SetCookie(), because Response.Cookies.Add() can cause multiple cookies to be added, whereas SetCookie will update an existing cookie.

I have been banging my head against the wall with a similar problem. The only thing that helped is following the steps in this post.

You cannot specify target table for delete.

A workaround

create table term_hierarchy_backup (tid int(10)); <- check data type

insert into term_hierarchy_backup 
SELECT DISTINCT(th1.tid)
FROM term_hierarchy AS th1
INNER JOIN term_hierarchy AS th2 ON (th1.tid = th2.tid AND th2.parent != 1015)
WHERE th1.parent = 1015;

DELETE FROM term_hierarchy AS th
WHERE th.parent = 1015 AND th.tid IN (select tid from term_hierarchy_backup);

chunks = [data[100*i:100*(i+1)] for i in range(len(data)/100 + 1)]

This is equivalent to the accepted answer. For example, shortening to batches of 10 for readability:

data = range(35)
print [data[x:x+10] for x in xrange(0, len(data), 10)]
print [data[10*i:10*(i+1)] for i in range(len(data)/10 + 1)]

Outputs:

[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19], [20, 21, 22, 23, 24, 25, 26, 27, 28, 29], [30, 31, 32, 33, 34]]

I was trying to run this on a pi zero. Turns out the pi zero has an armv6l architecture so the above won't work for pi zero or pi one. Alternatively here I learned that miniconda doesn't have a recent version of miniconda. Instead I used the same instructions posted here to install berryconda3

Conda is now working. Hope this helps those of you interested in running conda on the pi zero!

As VardhanDotNet mentions, %1 is enough.

"%1%" would add quotes around quotes: ""c:\Program Files\xxx"" which means:

• 'empty string' (""),
• followed by 'c:\Program',
• followed by the "unexpected here" 'Files\xxx',
• followed by an empty string ("")

Note however that if you need to use PWA_PATH within your IF clause, you need to refer if as !PWA_PATH! (hence the enabledelayedexpansion as the beginning of the script)

You need to do that on your binding, but you'll need to do it on both Client and Server. Something like:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding maxBufferSize="64000000" maxReceivedMessageSize="64000000" />
        </basicHttpBinding>
    </bindings>
</system.serviceModel>

You have a list of options which are far better than using a request body with GET.

Let' assume you have categories and items for each category. Both to be identified by an id ("catid" / "itemid" for the sake of this example). You want to sort according to another parameter "sortby" in a specific "order". You want to pass parameters for "sortby" and "order":

You can:

1. Use query strings, e.g. example.com/category/{catid}/item/{itemid}?sortby=itemname&order=asc
2. Use mod_rewrite (or similar) for paths: example.com/category/{catid}/item/{itemid}/{sortby}/{order}
3. Use individual HTTP headers you pass with the request
4. Use a different method, e.g. POST, to retrieve a resource.

All have their downsides, but are far better than using a GET with a body.

I thinks this is the best example for using randomUUID :

Using an example data.frame and example function (just +1 to all values)

A <- function(x) x + 1
wifi <- data.frame(replicate(9,1:4))
wifi

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  1  1  1  1  1  1
#2  2  2  2  2  2  2  2  2  2
#3  3  3  3  3  3  3  3  3  3
#4  4  4  4  4  4  4  4  4  4

data.frame(wifi[1:3], apply(wifi[4:9],2, A) )
#or
cbind(wifi[1:3], apply(wifi[4:9],2, A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3
#3  3  3  3  4  4  4  4  4  4
#4  4  4  4  5  5  5  5  5  5

Or even:

data.frame(wifi[1:3], lapply(wifi[4:9], A) )
#or
cbind(wifi[1:3], lapply(wifi[4:9], A) )

#  X1 X2 X3 X4 X5 X6 X7 X8 X9
#1  1  1  1  2  2  2  2  2  2
#2  2  2  2  3  3  3  3  3  3
#3  3  3  3  4  4  4  4  4  4
#4  4  4  4  5  5  5  5  5  5
