Try this :

import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;


public class Test {

    public static void main(String[] args) {
        JFrame f = new JFrame();
        try {
            f.setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("test.jpg")))));
        } catch (IOException e) {
            e.printStackTrace();
        }
        f.pack();
        f.setVisible(true);
    }

}

By the way, this will result in the content pane not being a container. If you want to add things to it you have to subclass a JPanel and override the paintComponent method.

Here is the corresponding presentViewController version that I used if it helps other newbies like myself:

if ([self respondsToSelector:@selector(presentModalViewController:animated:)]) {
    [self performSelector:@selector(presentModalViewController:animated:) withObject:testView afterDelay:0];
} else {
    [self presentViewController:configView animated:YES completion:nil];
}
[testView.testFrame setImage:info]; //this doesn't work for performSelector
[testView.testText setHidden:YES];

I had used a ViewController 'generically' and was able to get the modal View to appear differently depending what it was called to do (using setHidden and setImage). and things were working nicely before, but performSelector ignores 'set' stuff, so in the end it seems to be a poor solution if you try to be efficient like I tried to be...

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

Try std::find

vector<int>::iterator it = std::find(v.begin(), v.end(), 123);

if(it==v.end()){

    std::cout<<"Element not found";
}

Jeffrey Richter recommends following:

    public sealed class Singleton
    {
        private static readonly Object s_lock = new Object();
        private static Singleton instance = null;
    
        private Singleton()
        {
        }
    
        public static Singleton Instance
        {
            get
            {
                if(instance != null) return instance;
                Monitor.Enter(s_lock);
                Singleton temp = new Singleton();
                Interlocked.Exchange(ref instance, temp);
                Monitor.Exit(s_lock);
                return instance;
            }
        }
    }

JSX tags (<Component/>) are clearly not standard javascript and have no special meaning if you put them inside a naked <script> tag for example. Hence all React files that contain them are JSX and not JS.

By convention, the entry point of a React application is usually .js instead of .jsx even though it contains React components. It could as well be .jsx. Any other JSX files usually have the .jsx extension.

In any case, the reason there is ambiguity is because ultimately the extension does not matter much since the transpiler happily munches any kinds of files as long as they are actually JSX.

My advice would be: don't worry about it.

I would:

for _ in range(3):
    do()

The _ is convention for a variable whose value you don't care about.

You might also see some people write:

[do() for _ in range(3)]

however that is slightly more expensive because it creates a list containing the return values of each invocation of do() (even if it's None), and then throws away the resulting list. I wouldn't suggest using this unless you are using the list of return values.

As mentioned the dear user @Calvintwr, the function math.log10 has problem in a number outside of a range [-999999999999997, 999999999999997], where we get floating point errors. I had this problem with the JavaScript (the Google V8 and the NodeJS) and the C (the GNU GCC compiler), so a 'purely mathematically' solution is impossible here.

Based on this gist and the answer the dear user @Calvintwr

import math


def get_count_digits(number: int):
    """Return number of digits in a number."""

    if number == 0:
        return 1

    number = abs(number)

    if number <= 999999999999997:
        return math.floor(math.log10(number)) + 1

    count = 0
    while number:
        count += 1
        number //= 10
    return count

I tested it on numbers with length up to 20 (inclusive) and all right. It must be enough, because the length max integer number on a 64-bit system is 19 (len(str(sys.maxsize)) == 19).

All example of codes tested with the Python 3.5

An enumeration is something of an inverse-array. What I believe you want is this:

const char * Week[] = { "", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };  // The blank string at the beginning is so that Sunday is 1 instead of 0.
cout << "Today is " << Week[2] << ", enjoy!";  // Or whatever you'de like to do with it.

Use the hasClass method:

jQueryCollection.hasClass(className);

or

$(selector).hasClass(className);

The argument is (obviously) a string representing the class you are checking, and it returns a boolean (so it doesn't support chaining like most jQuery methods).

Note: If you pass a className argument that contains whitespace, it will be matched literally against the collection's elements' className string. So if, for instance, you have an element,

<span class="foo bar" />

then this will return true:

$('span').hasClass('foo bar')

and these will return false:

$('span').hasClass('bar foo')
$('span').hasClass('foo  bar')

You probably missed package declaration

package my.demo.service;

}

This was still happening to me on version 6.3.9 on OSX. I downloaded 6.1.7 again to actually see the result grid again.

What a pain in the butt!

You may try the TryParse method which allows you to parse a string into an integer and return a boolean result indicating the success or failure of the operation.

int distance;
if (int.TryParse(txtEvDistance.Text, out distance))
{
    // it's a valid integer => you could use the distance variable here
}

You most likely ran out of battery and your postgresql server didn't shutdown correctly.

The easiest workaround is to download the official postgresql app and launch it: it will force the server to start (http://postgresapp.com/)

I looked for a C/C++ API for Google Voice for quite a while and never found anything close (the closest was a C# API). Since I really needed it, I decided to just write one myself:

http://github.com/mastermind202/GoogleVoice

I hope others find it useful. Feedback and suggestions welcome.

Here (http://www.dotnetperls.com/picturebox) there 3 ways to do this:

• Like you are doing.

• Using ImageLocation property of the PictureBox like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "../SamuderaJayaMotor.png";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

• Using an image from the web like:

  private void Form1_Load(object sender, EventArgs e)
  {
      PictureBox pb1 = new PictureBox();            
      pb1.ImageLocation = "http://www.dotnetperls.com/favicon.ico";
      pb1.SizeMode = PictureBoxSizeMode.AutoSize;
  }
  

And please, be sure that "../SamuderaJayaMotor.png" is the correct path of the image that you are using.

For me, this one worked without the sudo access.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

For more reference, please follow https://gist.github.com/mxcl/323731

I used this query and it worked for me:

CREATE EVENT `exec`
  ON SCHEDULE EVERY 5 SECOND
  STARTS '2013-02-10 00:00:00'
  ENDS '2015-02-28 00:00:00'
  ON COMPLETION NOT PRESERVE ENABLE
DO 
  call delete_rows_links();

The mother of all debugger is plain old print screen. Most of the time, you probably only want to inspect some simple objects, a quick and easy way is like this:

@result = fetch_result

p "--------------------------"
p @result

This will print out the contents of @result to STDOUT with a line in front for easy identification.

Bonus if you use a autoload / reload capable framework like Rails, you won't even need to restart your app. (Unless the code you are debugging is not reloaded due to framework specific settings)

I find this works for 90% of the use case for me. You can also use ruby-debug, but I find it overkill most of the time.

You mean like this?

class MyResourcePolicy : IResourcePolicy {
    private string version;

    public string Version {
        get {
            return this.version;
        }
        set {
            this.version = value;
        }
    }
}

It's finally here!

Here are a few examples:

// properties
foo?.bar
foo?.bar()
foo?.bar.baz()
foo?.bar?.baz()

// indexing
foo?.[0]
foo?.['bar']

// check if a function is defined before invoking
foo?.()
foo.bar?.()
foo?.bar?.()

But it doesn't work exactly the same as your assumption.

Instead of evaluating

foo?.bar

to this little code snippet we are all used to writing

foo ? foo.bar : null

it actually evaluates to

(foo === null || foo === undefined) ?
    undefined :
    foo.bar

which works for all the falsey values like an empty string, 0 or false.

I just don't have an explanation as to why they don't compile it to foo == null

Well, you just fire the desired click event:

$(".first").click(function(){
    $(".second").click(); 
    return false;
});

Use the category below and then apply border from Quartz into your image:

[yourimage.layer setBorderColor:[[UIColor whiteColor] CGColor]];
[yourimage.layer setBorderWidth:2];

@interface UIImage (AutoScaleResize)

- (UIImage *)imageByScalingAndCroppingForSize:(CGSize)targetSize;

    if (CGSizeEqualToSize(imageSize, targetSize) == NO)
    {

        CGFloat heightFactor = targetHeight / height;

        if (widthFactor > heightFactor)
        {
            scaleFactor = widthFactor; // scale to fit height
        }
        else
        {
            scaleFactor = heightFactor; // scale to fit width
        }

        scaledWidth  = width * scaleFactor;
        scaledHeight = height * scaleFactor;

        // center the image
        if (widthFactor > heightFactor)
        {
            thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5;
        }
        else
        {
            if (widthFactor < heightFactor)
            {
                thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5;

    }

    //pop the context to get back to the default
    UIGraphicsEndImageContext();

That's perfectly normal. If you want gulp-cli available on the command line, you need to install it globally.

npm install --global gulp-cli

See the install instruction.

Also, node_modules/.bin/ isn't in your $PATH. But it is automatically added by npm when running npm scripts (see this blog post for reference).

So you could add scripts to your package.json file:

{
    "name": "your-app",
    "version": "0.0.1",
    "scripts": {
        "gulp": "gulp",
        "minify": "gulp minify"
    }
}

You could then run npm run gulp or npm run minify to launch gulp tasks.

In addition to the answer, $ yarn cache clean removes all libraries from cache. If you want to remove a specific lib's cache run $ yarn cache dir to get the right yarn cache directory path for your OS, then $ cd to that directory and remove the folder with the name + version of the lib you want to cleanup.

break; leaves your loop.

continue; skips any code for the remainder of that loop and goes on to the next loop, so long as the condition is still true.

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

http://dev.mysql.com/doc/refman/5.1/en/alter-table.html

In addition to the other answers, on a recent C library (Posix 2008 compliant), you could use getline. See this answer (to a related question).

You don't need an IIF() at all here. The comparisons return true or false anyway.

Also, since this row visibility is on a group row, make sure you use the same aggregate function on the fields as you use in the fields in the row. So if your group row shows sums, then you'd put this in the Hidden property.

=Sum(Fields!OpeningStock.Value) = 0 And
Sum(Fields!GrossDispatched.Value) = 0 And 
Sum(Fields!TransferOutToMW.Value) = 0 And
Sum(Fields!TransferOutToDW.Value) = 0 And
Sum(Fields!TransferOutToOW.Value) = 0 And
Sum(Fields!NetDispatched.Value) = 0 And
Sum(Fields!QtySold.Value) = 0 And
Sum(Fields!StockAdjustment.Value) = 0 And
Sum(Fields!ClosingStock.Value) = 0

But with the above version, if one record has value 1 and one has value -1 and all others are zero then sum is also zero and the row could be hidden. If that's not what you want you could write a more complex expression:

=Sum(
    IIF(
        Fields!OpeningStock.Value=0 AND
        Fields!GrossDispatched.Value=0 AND
        Fields!TransferOutToMW.Value=0 AND
        Fields!TransferOutToDW.Value=0 AND 
        Fields!TransferOutToOW.Value=0 AND
        Fields!NetDispatched.Value=0 AND
        Fields!QtySold.Value=0 AND
        Fields!StockAdjustment.Value=0 AND
        Fields!ClosingStock.Value=0,
        0,
        1
    )
) = 0

This is essentially a fancy way of counting the number of rows in which any field is not zero. If every field is zero for every row in the group then the expression returns true and the row is hidden.

Use substr() with a negative number for the 2nd argument.

$newstring = substr($dynamicstring, -7);

From the php docs:

string substr ( string $string , int $start [, int $length ] )

If start is negative, the returned string will start at the start'th character from the end of string.

I would suggest that you use the fyiReporting (Forked and Moved Now Current as of 2012) tool if you are looking to replace Crystal Reports. I have used both fyiReporting and Crystal and would have to say that I prefer fyiReporting(though their website is ghetto).

Reasons for choosing fyiReporting

1. If you want to replace Crystal then you are used to having a Report designer. FyiReporting has its own GUI just like Crystal Reports for creating and running reports(You could just create and distribute reports without building an application).

2. FyiReports allows you to export the Report as PDF, excel and mht(static web page) just to mention a few.

3. FyiReports are xml based so the report definition can be saved in a database and altered at anytime.

4. If you are using .Net FyiReporting has a Web and Windows Forms control for embedding the report in your applications(much like crystal reports). I am not so sure about Java as I am a .Net guy.

Anyway give FyiReports a try.

Try this:

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);

By combining Jason Robinson's answer with Felix's answer and filling the missing parts, here is the final complete solution for this issue that will do the following after testing it on Android Android 4.1 (Jelly Bean), Android 4.4 (KitKat) and Android 5.0 (Lollipop).

Steps

1. Scale down the image if it was bigger than 1024x1024.

2. Rotate the image to the right orientation only if it was rotate 90, 180 or 270 degree.

3. Recycle the rotated image for memory purposes.

Here is the code part:

Call the following method with the current Context and the image URI that you want to fix

/**
 * This method is responsible for solving the rotation issue if exist. Also scale the images to
 * 1024x1024 resolution
 *
 * @param context       The current context
 * @param selectedImage The Image URI
 * @return Bitmap image results
 * @throws IOException
 */
public static Bitmap handleSamplingAndRotationBitmap(Context context, Uri selectedImage)
        throws IOException {
    int MAX_HEIGHT = 1024;
    int MAX_WIDTH = 1024;

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    imageStream = context.getContentResolver().openInputStream(selectedImage);
    Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);

    img = rotateImageIfRequired(context, img, selectedImage);
    return img;
}

Here is the CalculateInSampleSize method from the pre mentioned source:

/**
  * Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
  * bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates
  * the closest inSampleSize that will result in the final decoded bitmap having a width and

  * @param reqWidth  The requested width of the resulting bitmap
  * @param reqHeight The requested height of the resulting bitmap
  * @return The value to be used for inSampleSize
  */
private static int calculateInSampleSize(BitmapFactory.Options options,
                                         int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee a final image
        // with both dimensions larger than or equal to the requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;

        // This offers some additional logic in case the image has a strange
        // aspect ratio. For example, a panorama may have a much larger
        // width than height. In these cases the total pixels might still
        // end up being too large to fit comfortably in memory, so we should
        // be more aggressive with sample down the image (=larger inSampleSize).

        final float totalPixels = width * height;

        // Anything more than 2x the requested pixels we'll sample down further
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
    }
    return inSampleSize;
}

Then comes the method that will check the current image orientation to decide the rotation angle

 /**
 * Rotate an image if required.
 *
 * @param img           The image bitmap
 * @param selectedImage Image URI
 * @return The resulted Bitmap after manipulation
 */
private static Bitmap rotateImageIfRequired(Context context, Bitmap img, Uri selectedImage) throws IOException {

InputStream input = context.getContentResolver().openInputStream(selectedImage);
ExifInterface ei;
if (Build.VERSION.SDK_INT > 23)
    ei = new ExifInterface(input);
else
    ei = new ExifInterface(selectedImage.getPath());

    int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            return rotateImage(img, 90);
        case ExifInterface.ORIENTATION_ROTATE_180:
            return rotateImage(img, 180);
        case ExifInterface.ORIENTATION_ROTATE_270:
            return rotateImage(img, 270);
        default:
            return img;
    }
}

Finally the rotation method itself

private static Bitmap rotateImage(Bitmap img, int degree) {
    Matrix matrix = new Matrix();
    matrix.postRotate(degree);
    Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
    img.recycle();
    return rotatedImg;
}

With mockito you can use withSettings(), for example if the CounterService required 2 dependencies, you can pass them as a mock:

UserService userService = Mockito.mock(UserService.class); SearchService searchService = Mockito.mock(SearchService.class); CounterService counterService = Mockito.mock(CounterService.class, withSettings().useConstructor(userService, searchService));

As of v1.8.8 there is also the option USE_MDFILE_AS_MAINPAGE. So make sure to add your index file, e.g. README.md, to INPUT and set it as this option's value:

INPUT += README.md
USE_MDFILE_AS_MAINPAGE = README.md

When this happens, look in the Errors window and the Output window to see if there are any error messages. If that doesn't help, try running svcutil.exe manually, and see if there are any error messages.

If this happens when testing on the iPhone. Just restart the phone. From what I have been told the phone or simulator still believes there is an instance of the app running, so when it was last run it had not terminated correctly do to either an error in your code or the phone/simulator just wanted to have a moan.

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

This piece of code worked for me. What I was missing was I was not passing 'this' in button action:

 onPress={this._handlePress.bind(this)}>
--------------

  _handlePress(event) {
console.log('Pressed!');

 var username = this.state.username;
 var password = this.state.password;

 console.log(username);
 console.log(password);
}

  render() {
    return (
      <View style={styles.container}>

      <TextInput
      ref="usr"
      style={{height: 40, borderColor: 'gray', borderWidth: 1 , marginTop: 10 , padding : 10 , marginLeft : 5 , marginRight : 5 }}
      placeHolder= "Enter username "
      placeholderTextColor = '#a52a2a'

      returnKeyType = {"next"}
      autoFocus = {true}
      autoCapitalize = "none"
      autoCorrect = {false}
      clearButtonMode = 'while-editing'
      onChangeText={(text) => {
          this.setState({username:text});
        }}
      onSubmitEditing={(event) => {
     this.refs.psw.focus();

      }}
      />

      <TextInput
      ref="psw"
      style={{height: 40, borderColor: 'gray', borderWidth: 1 , marginTop: 10,marginLeft : 5 , marginRight : 5}}
      placeholder= "Enter password"
      placeholderTextColor = '#a52a2a'
      autoCapitalize = "none"
      autoCorrect = {false}
      returnKeyType = {'done'}
      secureTextEntry = {true}
      clearButtonMode = 'while-editing'
      onChangeText={(text) => {
          this.setState({password:text});
        }}
      />

      <Button
        style={{borderWidth: 1, borderColor: 'blue'}}
        onPress={this._handlePress.bind(this)}>
        Login
      </Button>

      </View>
    );``
  }
}

I know this is late but it might be of some use:

echo "<pre>";
print_r($array);
echo "</pre>";

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

Putting the expressions in a list may simulate multiple expressions:

E.g.:

lambda x: [f1(x), f2(x), f3(x), x+1]

This will not work with statements.

You can use stepi or nexti (which can be abbreviated to si or ni) to step through your machine code.

First, implement indexOf in JavaScript for browsers that don't already have it. For example, see Erik Arvidsson's array extras (also, the associated blog post). And then you can use indexOf without worrying about browser support. Here's a slightly optimised version of his indexOf implementation:

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function (obj, fromIndex) {
        if (fromIndex == null) {
            fromIndex = 0;
        } else if (fromIndex < 0) {
            fromIndex = Math.max(0, this.length + fromIndex);
        }
        for (var i = fromIndex, j = this.length; i < j; i++) {
            if (this[i] === obj)
                return i;
        }
        return -1;
    };
}

It's changed to store the length so that it doesn't need to look it up every iteration. But the difference isn't huge. A less general purpose function might be faster:

var include = Array.prototype.indexOf ?
    function(arr, obj) { return arr.indexOf(obj) !== -1; } :
    function(arr, obj) {
        for(var i = -1, j = arr.length; ++i < j;)
            if(arr[i] === obj) return true;
        return false;
    };

I prefer using the standard function and leaving this sort of micro-optimization for when it's really needed. But if you're keen on micro-optimization I adapted the benchmarks that roosterononacid linked to in the comments, to benchmark searching in arrays. They're pretty crude though, a full investigation would test arrays with different types, different lengths and finding objects that occur in different places.

On older notebooks with integrated video Swing app starts and works much faster than JavaFX app. As for development, I'd recommend switch to Scala - comparable Scala Swing app contains 2..3 times less code than Java. As for Swing vs SWT: Netbeans GUI considerably faster than Eclipse...

If you want to use the JavaScript download functionality then you can also do

 <a onclick=“window.open(‘info.pdf) class="btn btn-large pull-right"><i class="icon-download-alt"> </i> Download Brochure </a>

Its seems that server is not running properly so ensure that with terminal by

telnet ip port

example

telnet localhost 8069

It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection

This usually occurs because either of the following are true:

• The certificate is self-signed and not added as a trusted certificate.
• The certificate is expired.
• The certificate is signed by a root certificate that's not installed on your machine.
• The certificate is signed using the fully qualified domain address of the server. Meaning: cannot use "xyzServerName" but instead must use "xyzServerName.ad.state.fl.us" because that's basically the server name as far as the SSL cert is concerned.
• A revocation list is probed, but cannot be found/used.
• The certificate is signed via intermediate CA certificate and server does not serve that intermediate certificate along with host certificate.

Try getting some information about the certificate of the server and see if you need to install any specific certs on your client to get it to work.

Assuming the title of your question is correct and you want the time:

SELECT CONVERT(char,GETDATE(),14)

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

To Answer your first question, Jenkins variables are case sensitive. However, if you are writing a windows batch script, they are case insensitive, because Windows doesn't care about the case.

Since you are not very clear about your setup, let's make the assumption that you are using an ant build step to fire up your ant task. Have a look at the Jenkins documentation (same page that Adarsh gave you, but different chapter) for an example on how to make Jenkins variables available to your ant task.

EDIT:

Hence, I will need to access the environmental variable ${BUILD_NUMBER} to construct the URL.

Why don't you use $BUILD_URL then? Isn't it available in the extended email plugin?

First checkout to the branch which you want to rename:

git branch -m old_branch new_branch
git push -u origin new_branch

To remove an old branch from remote:

git push origin :old_branch

You can use CSS transformations to achieve this. A horizontal flip would involve scaling the div like this:

-moz-transform: scale(-1, 1);
-webkit-transform: scale(-1, 1);
-o-transform: scale(-1, 1);
-ms-transform: scale(-1, 1);
transform: scale(-1, 1);

And a vertical flip would involve scaling the div like this:

-moz-transform: scale(1, -1);
-webkit-transform: scale(1, -1);
-o-transform: scale(1, -1);
-ms-transform: scale(1, -1);
transform: scale(1, -1);

DEMO:

span{ display: inline-block; margin:1em; } _x000D_
.flip_H{ transform: scale(-1, 1); color:red; }_x000D_
.flip_V{ transform: scale(1, -1); color:green; }

<span class='flip_H'>Demo text &#9986;</span>_x000D_
<span class='flip_V'>Demo text &#9986;</span>

TTFB is something that happens behind the scenes. Your browser knows nothing about what happens behind the scenes.

You need to look into what queries are being run and how the website connects to the server.

This article might help understand TTFB, but otherwise you need to dig deeper into your application.

For 8085: Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address of the top of the stack.

The stack pointer register in a computer is made available for general purpose use by programs executing at lower privilege levels than interrupt handlers. A set of instructions in such programs, excluding stack operations, stores data other than the stack pointer, such as operands, and the like, in the stack pointer register. When switching execution to an interrupt handler on an interrupt, return address data for the currently executing program is pushed onto a stack at the interrupt handler's privilege level. Thus, storing other data in the stack pointer register does not result in stack corruption. Also, these instructions can store data in a scratch portion of a stack segment beyond the current stack pointer.

Read this one for more info.

You could use DocChow, a very intuitive GIU for importing Excel into MySQL, and it's free on most common platforms (including Linux).

More especially if you are concerned about date, datetime datatypes, DocChow easily handles datatypes. If you are working with multiple Excel spreadsheets that you want to import into one MySQL table DocChow does the dirty work.

well, this using lodash or vanilla javascript it depends on the situation.

but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

Guys I just found a solution. Given that TortoiseSVN works the way we want, I tried to install it under Linux - which means, running on Wine. Surprisingly it works! All you have to do is:

1. Add files you want to skip commit by running: "svn changelist 'ignore-on-commit' ".
2. Use TortoiseSVN to commit: "~/.wine/drive_c/Program\ Files/TortoiseSVN/bin/TortoiseProc.exe /command:commit /path:'
3. The files excluded will be unchecked for commit by default, while other modified files will be checked. This is exactly the same as under Windows. Enjoy!

(The reason why need to exclude files by CLI is because the menu entry for doing that was not found, not sure why. Any way, this works great!)

I have a .bat file on my quick task bar (windows) with:

taskkill /F /IM java.exe

It's very quick, but it may not be good in many situations!

it takes this command about 2 mins to return the data as there is a lot of data

Probably, Bad Design. Consider using paging here.

default connection time is 30 secs, how do I increase this

As you are facing a timeout on your command, therefore you need to increase the timeout of your sql command. You can specify it in your command like this

// Setting command timeout to 2 minutes
scGetruntotals.CommandTimeout = 120;

//div[@id='..' and @class='...]

should do the trick. That's selecting the div operators that have both attributes of the required value.

It's worth using one of the online XPath testbeds to try stuff out.

Daniel A. White Solution works great for classes.

I've got a situation where I had to find input fields like donee_1_card where 1 is an index.

My solution has been

$("input[name^='donee']" && "input[name*='card']")

Though I am not sure how optimal it is.

There was a previous question today (no answers) that gave a good example of this functionality. You can check the relevant source code for specifics (search for "toolbar"), but basically they use a combination of webdestroya's solution and a bit of JavaScript:

1. Page loads and element is position: static
2. On scroll, the position is measured, and if the element is position: static and it's off the page then the element is flipped to position: fixed.

I'd recommend checking the aforementioned source code though, because they do handle some "gotchas" that you might not immediately think of, such as adjusting scroll position when clicking on anchor links.

Not javascript free i'm afraid, but I managed to make it quite small using jQuery

$('#del_select').mouseenter(function () {

    $(this).css("width","auto");

});

$('#del_select').mouseout(function () {

    $(this).css("width","170px");

}); 

I solved the problem this way:

• On the orange WAMP icon, click Apache > Service > Test Port 80. Came back with "Port 80 not accessible -- (could be Skype)"
• Sign out from Skype and close program.
• Click orange icon and hit Apache > Service > Install Service
• Click orange icon and hit Apache > Service > Start Service
• Click orange icon and hit Put Online
• Icon turns green and service is started and online

tl;dr

I contrast them in two ways:

joins - For conditional selection of records.

includes - When using an association on each member of a result set.

Longer version

Joins is meant to filter the result set coming from the database. You use it to do set operations on your table. Think of this as a where clause that performs set theory.

Post.joins(:comments)

is the same as

Post.where('id in (select post_id from comments)')

Except that if there are more than one comment you will get duplicate posts back with the joins. But every post will be a post that has comments. You can correct this with distinct:

Post.joins(:comments).count
=> 10
Post.joins(:comments).distinct.count
=> 2

In contract, the includes method will simply make sure that there are no additional database queries when referencing the relation (so that we don't make n + 1 queries)

Post.includes(:comments).count
=> 4 # includes posts without comments so the count might be higher.

The moral is, use joins when you want to do conditional set operations and use includes when you are going to be using a relation on each member of a collection.

Use a DataTrigger:

<DataGrid ItemsSource="{Binding YourItemsSource}">
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow"> 
            <Style.Triggers>
                <DataTrigger Binding="{Binding State}" Value="State1">
                    <Setter Property="Background" Value="Red"></Setter>
                </DataTrigger>
                <DataTrigger Binding="{Binding State}" Value="State2">
                    <Setter Property="Background" Value="Green"></Setter>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

I would stick with normal approach to call the file directly, but if you really want to call a function, have a look at JSON-RPC (JSON Remote Procedure Call).

You basically send a JSON string in a specific format to the server, e.g.

{ "method": "echo", "params": ["Hello JSON-RPC"], "id": 1}

which includes the function to call and the parameters of that function.

Of course the server has to know how to handle such requests.
Here is jQuery plugin for JSON-RPC and e.g. the Zend JSON Server as server implementation in PHP.

This might be overkill for a small project or less functions. Easiest way would be karim's answer. On the other hand, JSON-RPC is a standard.

I'll suggest different approach, If the order of the items inside the list is not important at extraction (and each item should be selected only once), then instead of a List you can use a ConcurrentBag which is a thread-safe, unordered collection of objects:

var bag = new ConcurrentBag<string>();
bag.Add("Foo");
bag.Add("Boo");
bag.Add("Zoo");

The EventHandler:

string result;
if (bag.TryTake(out result))
{
    MessageBox.Show(result);
}

The TryTake will attempt to extract an "random" object from the unordered collection.

$('inputFile').parent().parent().children('td > label').hide();

can help you navigate two levels up ( to TD, to TR ) moving two levels back down ( all TD's in that TR and their LABEL tags ), applying the hide() function there.

if you want to stay at the TR level and hide them:

$('inputFile').parent().parent().hide();

… is sufficient.

you can navigate very easily through the elements using the jquery selectors.

parent is documented here: http://api.jquery.com/parent/

hide is documented here: http://api.jquery.com/hide/

Here's a simple way.

Disclaimer: This is not a perfect solution - I am only posting it for devs who are under a timeline and have lots of data to import and are encountering this ridiculous issue. I lost a lot of time on this and I hope to spare another dev the same lost time.

Note: This answer is outdated. See the answer for newer versions of Flutter.

You can dismiss the keyboard by taking away the focus of the TextFormField and giving it to an unused FocusNode:

FocusScope.of(context).requestFocus(FocusNode());

I do not work with google android but I think you'll find it's not that hard to get this working. If you read the relevant bit of the java tutorial you'll see that a registered cookiehandler gets callbacks from the HTTP code.

So if there is no default (have you checked if CookieHandler.getDefault() really is null?) then you can simply extend CookieHandler, implement put/get and make it work pretty much automatically. Be sure to consider concurrent access and the like if you go that route.

edit: Obviously you'd have to set an instance of your custom implementation as the default handler through CookieHandler.setDefault() to receive the callbacks. Forgot to mention that.

I had the requirement to retrieve all properties whose key starts with a distinct prefix (e.g. all properties starting with "log4j.appender.") and wrote following Code (using streams and lamdas of Java 8).

public static Map<String,Object> getPropertiesStartingWith( ConfigurableEnvironment aEnv,
                                                            String aKeyPrefix )
{
    Map<String,Object> result = new HashMap<>();

    Map<String,Object> map = getAllProperties( aEnv );

    for (Entry<String, Object> entry : map.entrySet())
    {
        String key = entry.getKey();

        if ( key.startsWith( aKeyPrefix ) )
        {
            result.put( key, entry.getValue() );
        }
    }

    return result;
}

public static Map<String,Object> getAllProperties( ConfigurableEnvironment aEnv )
{
    Map<String,Object> result = new HashMap<>();
    aEnv.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
    return result;
}

public static Map<String,Object> getAllProperties( PropertySource<?> aPropSource )
{
    Map<String,Object> result = new HashMap<>();

    if ( aPropSource instanceof CompositePropertySource)
    {
        CompositePropertySource cps = (CompositePropertySource) aPropSource;
        cps.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
        return result;
    }

    if ( aPropSource instanceof EnumerablePropertySource<?> )
    {
        EnumerablePropertySource<?> ps = (EnumerablePropertySource<?>) aPropSource;
        Arrays.asList( ps.getPropertyNames() ).forEach( key -> result.put( key, ps.getProperty( key ) ) );
        return result;
    }

    // note: Most descendants of PropertySource are EnumerablePropertySource. There are some
    // few others like JndiPropertySource or StubPropertySource
    myLog.debug( "Given PropertySource is instanceof " + aPropSource.getClass().getName()
                 + " and cannot be iterated" );

    return result;

}

private static void addAll( Map<String, Object> aBase, Map<String, Object> aToBeAdded )
{
    for (Entry<String, Object> entry : aToBeAdded.entrySet())
    {
        if ( aBase.containsKey( entry.getKey() ) )
        {
            continue;
        }

        aBase.put( entry.getKey(), entry.getValue() );
    }
}

Note that the starting point is the ConfigurableEnvironment which is able to return the embedded PropertySources (the ConfigurableEnvironment is a direct descendant of Environment). You can autowire it by:

@Autowired
private ConfigurableEnvironment  myEnv;

If you not using very special kinds of property sources (like JndiPropertySource, which is usually not used in spring autoconfiguration) you can retrieve all properties held in the environment.

The implementation relies on the iteration order which spring itself provides and takes the first found property, all later found properties with the same name are discarded. This should ensure the same behaviour as if the environment were asked directly for a property (returning the first found one).

Note also that the returned properties are not yet resolved if they contain aliases with the ${...} operator. If you want to have a particular key resolved you have to ask the Environment directly again:

myEnv.getProperty( key );

This change only first handle in multihandle slider. In apiDoc you can see:"For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two."

  try {
        $result=DB::table('users')->whereExists(function ($Query){
            $Query->where('id','<','14162756');
            $Query->whereBetween('password',[14162756,48384486]);
            $Query->whereIn('id',[3,8,12]);
        });
    }catch (\Exception $error){
        Log::error($error);
        DB::rollBack(1);
        return redirect()->route('bye');
    }

Copy the below script "ez_setup.py" from the below URL

https://bootstrap.pypa.io/ez_setup.py

And copy it into your Python location

C:\Python27>

Run the command

C:\Python27? python ez_setup.py

This will install the easy_install under Scripts directory

C:\Python27\Scripts

Run easy install from the Scripts directory >

C:\Python27\Scripts> easy_install

2 things to understand here -

1) If you are casting Primitive interger to Primitive double . It works. e.g. It works fine.

int pri=12; System.out.println((double)pri);

2) if you try to Cast Integer object to Double object or vice - versa , It fails.

Integer a = 1; Double b = (double) a; // WRONG. Fails with class cast excptn

Solution -

Soln 1) Integer i = 1; Double b = new Double(i);
soln 2) Double d = 2.0; Integer x = d.intValue();

You need to delete it by order There are dependency in the tables

If the size of the subdirectory is not particularly huge, AND you wish to stay away from the CLI, here's a quick solution to manually reset the sub-directory:

1. Switch to master branch and copy the sub-directory to be reset.
2. Now switch back to your feature branch and replace the sub-directory with the copy you just created in step 1.
3. Commit the changes.

Cheers. You just manually reset a sub-directory in your feature branch to be same as that of master branch !!

You can actually try this yourself, that should help you get a feel for how this works.

Open a two windows (tabs) in management studio, each of them will have it's own connection to sql.

Now you can begin a transaction in one window, do some stuff like insert/update/delete, but not yet commit. then in the other window you can see how the database looks from outside the transaction. Depending on the isolation level, the table may be locked until the first window is committed, or you might (not) see what the other transaction has done so far, etc.

Play around with the different isolation levels and no lock hint to see how they affect the results.

Also see what happens when you throw an error in the transaction.

It's very important to understand how all this stuff works or you will be stumped by what sql does, many a time.

Have fun! GJ.

In our days you actually can do your approach with JS:

// Your variable is null
// or '', 0, false, undefined
let x = null;

// Set default value
x = x || 'default value';

console.log(x); // default value

So your example WILL work:

const setVariable = localStorage.getItem('value') || 0;

Since I found this question not being aware, that mysql always stores time in timestamp fields in UTC but will display (e.g. phpmyadmin) in local time zone I would like to add my findings.

I have an automatically updated last_modified field, defined as:

`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Looking at it with phpmyadmin, it looks like it is in local time, internally it is UTC

SET time_zone = '+04:00'; // or '+00:00' to display dates in UTC or 'UTC' if time zones are installed.
SELECT last_modified, UNIX_TIMESTAMP(last_modified), from_unixtime(UNIX_TIMESTAMP(last_modified), '%Y-%c-%d %H:%i:%s'), CONVERT_TZ(last_modified,@@session.time_zone,'+00:00') as UTC FROM `table_name`

In any constellation, UNIX_TIMESTAMP and 'as UTC' are always displayed in UTC time.

Run this twice, first without setting the time_zone.

This happened to me. Solved by editing .plist file. Specify the Main nib file base name.(Should be MainWindow.xib). Hope this will help.

Assertj is good at this.

import static org.assertj.core.api.Assertions.assertThat;

    assertThat(myClass.getMyItems()).extracting("name").contains("foo", "bar");

Big plus for assertj compared to hamcrest is easy use of code completion.

public static void main(String[] args) {
    @SuppressWarnings("serial")
    List<Object> lst = new ArrayList<Object>() {
        @Override
        public boolean add(Object e) {
            if(!contains(e))
            return super.add(e);
            else
            return false;
        }
    };
    lst.add("ABC");
    lst.add("ABC");
    lst.add("ABCD");
    lst.add("ABCD");
    lst.add("ABCE");
    System.out.println(lst);

}

This is the better way

EDIT: I'm torn on whether to delete this post. As a matter of understanding the CSS syntax, it's good that people know all exists, and it may at times be preferable to a million individual declarations, depending on the structure of your CSS. On the other hand, it may have a performance penalty, although I've yet to see any data supporting that hypothesis. For now, I'll leave it, but I want people to be aware it's a mixed bag.

Original post:

You can also simply significantly with:

.nav a {
    transition: all .2s;
}

FWIW: all is implied if not specified, so transition: .2s; will get you to the same place.

This is an easy way for any format. Just change it to required format string

XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);

You cannot truncate a table if you don't drop the constraints. A disable also doesn't work. you need to Drop everything. i've made a script that drop all constrainsts and then recreate then.

Be sure to wrap it in a transaction ;)

One more method is to Define the Layout inside the View:

   @{
    Layout = "~/Views/Shared/_MyAdminLayout.cshtml";
    }

More Ways to do, can be found here, hope this helps someone.

Use @temp tables whenever possible--that is, you only need one primary key and you do not need to access the data from a subordinate stored proc.

Use #temp tables if you need to access the data from a subordinate stored proc (it is an evil global variable to the stored proc call chain) and you have no other clean way to pass the data between stored procs. Also use it if you need a secondary index (although, really ask yourself if it is a #temp table if you need more than one index)

If you do this, always declare your #temp table at the top of the function. SQL will force a recompile of your stored proc when it sees the create table statement....so if you have the #temp table declaration in the middle of the stored proc, you stored proc must stop processing and recompile.

As suggested by @linqu you should not change your data for presentation. Since pandas 0.17.1, (conditional) formatting was made easier. Quoting the documentation:

You can apply conditional formatting, the visual styling of a DataFrame depending on the data within, by using the DataFrame.style property. This is a property that returns a pandas.Styler object, which has useful methods for formatting and displaying DataFrames.

For your example, that would be (the usual table will show up in Jupyter):

df.style.format({
    'var1': '{:,.2f}'.format,
    'var2': '{:,.2f}'.format,
    'var3': '{:,.2%}'.format,
})

I made a simple JQuery plugin for this if anyone is interested.

http://plugins.jquery.com/pressAndHold/

If you are using Bootstrap date picker, then you can just add data_date_format attribute as below.

      @Html.TextBoxFor(m => m.StartDate, new { 
@id = "your-id", @class = "datepicker form-control input-datepicker", placeholder = "dd/mm/yyyy", data_date_format = "dd/mm/yyyy" 
})

Here, when clicking next or previous, the src attribute of an img tag is changed to the next or previous value in an array.

<div id="imageGallery">    
    <img id="image" src="http://adamyost.com/images/wasatch_thumb.gif" />
    <div id="previous">Previous</div>    
    <div id="next">Next</div>        
</div>

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

<script>
    $( document ).ready(function() {

        var images = [
            "http://placehold.it/350x150",
            "http://placehold.it/150x150",
            "http://placehold.it/50x150"    
        ];

        var imageIndex = 0;

        $("#previous").on("click", function(){          
            imageIndex = (imageIndex + images.length -1) % (images.length);    
            $("#image").attr('src', images[imageIndex]);
        });

        $("#next").on("click", function(){
            imageIndex = (imageIndex+1) % (images.length);    
            $("#image").attr('src', images[imageIndex]);
        });

        $("#image").attr(images[0]);

    });
</script>

I was able to implement this by modifying this answer: jQuery array with next and previous buttons to scroll through entries

The 2 highest upvoted answers are correct. As of today, the only thing I needed to change (from default settings) was to enable generation using dot instead of the built-in generator.

Some important notes:

• Doxygen will not generate an actual full diagram of all classes in the project. It will generate a separate image for each hierarchy. If you have multiple, unrelated class hierarchies you will get multiple images.
• All these diagrams can be found in html/inherits.html or (from the website navigation) classes => class hierarchy => "Go to the textual class hierarchy".
• This is a C++ question, so let's talk about templates. Especially if you inherit from T.
  • Each template instantiation will be correctly considered a different type by Doxygen. Types which inherit from different instantations will have different parent classes on the diagram.
  • If a class template foo inherits from T and the T template type parameter has a default, such default will be assumed. If there is a type bar which inherits from foo<U> where U is different than the default, bar will have a foo<U> parent. foo<> and bar<U> will not have a common parent.
  • If there are multiple class templates which inherit from at least one of their template parameters, Doxygen will assume a common parent for these class templates as long as the template type parameters have exactly the same names in the code. This incentivizes for consistency in naming.
  • CRTP and reverse CRTP just work.
  • Recursive template inheritance trees are not expanded. Any variant instantiation will be displayed to inherit from variant<Ts...>.
  • Class templates with no instantiations are being drawn. They will have a <...> string in their name representing type and non-type parameters which did not have defaults.
  • Class template full and partial specializations are also being drawn. Doxygen generates correct graphs if specializations inherit from different types.

The same issue i was facing couple of months back and that is because end of free google map usage effective from i think June 11, 2018. Google does not provide free google maps now. You need to have a valid API key and valid billing used, which may give you 200$ of free usage.

Refer link for more details: Google map pricing

Follow the process here to get your api key.

If you are upto using only maps with specific user, you can try other map tools.

It for example happens in this case here:

void initializeJSP(unknownType Experiment);

Try using std::string instead of just string (and include the <string> header). C++ Standard library classes are within the namespace std::.

Check the jsfiddle http://jsfiddle.net/CdwB9/3/ and click on delete

function yesnodialog(button1, button2, element){
  var btns = {};
  btns[button1] = function(){ 
      element.parents('li').hide();
      $(this).dialog("close");
  };
  btns[button2] = function(){ 
      // Do nothing
      $(this).dialog("close");
  };
  $("<div></div>").dialog({
    autoOpen: true,
    title: 'Condition',
    modal:true,
    buttons:btns
  });
}
$('.delete').click(function(){
    yesnodialog('Yes', 'No', $(this));
})

This should help you

In addition to the solution you accepted, you could also implement the special __lt__() ("less than") method on the class. The sort() method (and the sorted() function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.

class Foo(object):

     def __init__(self, score):
         self.score = score

     def __lt__(self, other):
         return self.score < other.score

l = [Foo(3), Foo(1), Foo(2)]
l.sort()

I've found my own solution.

Download FreeDOS from here: http://chtaube.eu/computers/freedos/bootable-usb/

Then using my Counter.exe file (which basically generates a Counter.txt file and increments the number inside every time it's being called), I can assign the value of the number to a variable using:

Set /P Variable =< Counter.txt

Then, I can check if it has run 250 cycles by doing:

if %variable%==250 echo PASS

BTW, I still can't use Set /A since FreeDOS doesn't support this command, but at least it supports the Set /P command.

The short answer for this is, "because that's what the C++ standard specifies".

Note that you can always specify a constructor that's different from the default, like so:

class Shape  {

  Shape()  {...} //default constructor
  Shape(int h, int w) {....} //some custom constructor


};

class Rectangle : public Shape {
  Rectangle(int h, int w) : Shape(h, w) {...} //you can specify which base class constructor to call

}

The default constructor of the base class is called only if you don't specify which one to call.

wordpressProject is the project name.

Thanks. It will work.

One-line numpy solution for downsampling (by 2):

smaller_img = bigger_img[::2, ::2]

And upsampling (by 2):

bigger_img = smaller_img.repeat(2, axis=0).repeat(2, axis=1)

(this asssumes HxWxC shaped image. h/t to L. Kärkkäinen in the comments above. note this method only allows whole integer resizing (e.g., 2x but not 1.5x))

1 - You can set a timeout in your application :

var client = new YourServiceReference.YourServiceClass();
client.Timeout = 60; // or -1 for infinite

It is in milliseconds.

2 - Also you can increase timeout value in httpruntime tag in web/app.config :

<configuration>
     <system.web>
          <httpRuntime executionTimeout="<<**seconds**>>" />
          ...

For ASP.NET applications, the Timeout property value should always be less than the executionTimeout attribute of the httpRuntime element in Machine.config. The default value of executionTimeout is 90 seconds. This property determines the time ASP.NET continues to process the request before it returns a timed out error. The value of executionTimeout should be the proxy Timeout, plus processing time for the page, plus buffer time for queues. -- Source

As mentioned previously "there is no CSS selector for selecting a parent of a selected child".

So you either:

• use a CSS hack as described in NGLN's answer
• use javascript - along with jQuery most likely

Here is the example for the javascript/jQuery solution

On the javascript side:

$('#my-id-selector-00').on('mouseover', function(){
  $(this).parent().addClass('is-hover');
}).on('mouseout', function(){
  $(this).parent().removeClass('is-hover');
})

And on the CSS side, you'd have something like this:

.is-hover {
  background-color: red;
}

Why this answer is different

Every other answer either:

• Prints instead of returns
• Makes 2 recursive calls per iteration
• Ignores the question by using loops

(aside: none of these is actually efficient; use Binet's formula to directly calculate the n^th term)

Tail Recursive Fib

Here is a recursive approach that avoids a double-recursive call by passing both the previous answer AND the one before that.

private static final int FIB_0 = 0;
private static final int FIB_1 = 1;

private int calcFibonacci(final int target) {
    if (target == 0) { return FIB_0; }
    if (target == 1) { return FIB_1; }

    return calcFibonacci(target, 1, FIB_1, FIB_0);
}

private int calcFibonacci(final int target, final int previous, final int fibPrevious, final int fibPreviousMinusOne) {
    final int current = previous + 1;
    final int fibCurrent = fibPrevious + fibPreviousMinusOne;
    // If you want, print here / memoize for future calls

    if (target == current) { return fibCurrent; }

    return calcFibonacci(target, current, fibCurrent, fibPrevious);
}

I just came across a similar situation and was surprised at the rounding issues of 'very large numbers' presented within SSMS v17.9.1 / SQL 2017.

I am not suggesting I have a solution, however I have observed that FORMAT presents a number which appears correct. I can not imply this reduces further rounding issues or is useful within a complicated mathematical function.

T SQL Code supplied which should clearly demonstrate my observations while enabling others to test their code and ideas should the need arise.

The ASCII table is arranged so that the value of the character '9' is nine greater than the value of '0'; the value of the character '8' is eight greater than the value of '0'; and so on.

So you can get the int value of a decimal digit char by subtracting '0'.

char x = '9';
int y = x - '0'; // gives the int value 9

SJLJ (setjmp/longjmp): – available for 32 bit and 64 bit – not “zero-cost”: even if an exception isn’t thrown, it incurs a minor performance penalty (~15% in exception heavy code) – allows exceptions to traverse through e.g. windows callbacks

DWARF (DW2, dwarf-2) – available for 32 bit only – no permanent runtime overhead – needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown over e.g. Windows system DLLs.

SEH (zero overhead exception) – will be available for 64-bit GCC 4.8.

In Eclipse it is very easy to point Tomcat to a new JVM (in this example JRE6). My problem was I couldn't find where to do it. Here is the trick:

1. On the ECLIPSE top menu FILE pull down tab, select NEW, -->Other
2. ...on the New Server: Select A Wizard window, select: Server-> Server... click NEXT
3. . on the New Server: Define a New Server window, select Apache> Tomcat 7 Server
4. ..now click the line in blue and underlined entitled: Configure Runtime Environments
5. on the Server Runtime Environments window,
6. ..select Apache, expand it(click on the arrow to the left), select TOMCAT v7.0, and click EDIT.
7. you will see a window called EDIT SERVER RUNTIME ENVIRONMENT: TOMCAT SERVER
8. On this screen there is a pulldown labeled JREs.
9. You should find your JRE listed like JRE1.6.0.33. If not use the Installed JRE button.
10. Select the desired JRE. Click the FINISH button.
11. Gracefully exit, in the Server: Server Runtime Environments window, click OK
12. in the New Server: Define a new Server window, hit NEXT
13. in the New Server: Add and Remove Window, select apps and install them on the server.
14. in the New Server: Add and Remove Window, click Finish

That's all. Interesting, only steps 7-10 seem to matter, and they will change the JRE used on all servers you have previously defined to use TOMCAT v7.0. The rest of the steps are just because I can't find any other way to get to the screen except by defining a new server. Does anyone else know an easier way?

for (const s of myStringArray) {

(Directly answering your question: now you can!)

Most other answers are right, but they do not mention (as of this writing) that ECMAScript  6  2015 is bringing a new mechanism for doing iteration, the for..of loop.

This new syntax is the most elegant way to iterate an array in JavaScript (as long you don't need the iteration index).

It currently works with Firefox 13+, Chrome 37+ and it does not natively work with other browsers (see browser compatibility below). Luckily we have JavaScript compilers (such as Babel) that allow us to use next-generation features today.

It also works on Node.js (I tested it on version 0.12.0).

Iterating an array

// You could also use "let" or "const" instead of "var" for block scope.
for (var letter of ["a", "b", "c"]) {
   console.log(letter);
}

Iterating an array of objects

const band = [
  {firstName : 'John', lastName: 'Lennon'},
  {firstName : 'Paul', lastName: 'McCartney'}
];

for(const member of band){
  console.log(member.firstName + ' ' + member.lastName);
}

Iterating a generator:

(example extracted from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of)

function* fibonacci() { // A generator function
  let [prev, curr] = [1, 1];
  while (true) {
    [prev, curr] = [curr, prev + curr];
    yield curr;
  }
}

for (const n of fibonacci()) {
  console.log(n);
  // Truncate the sequence at 1000
  if (n >= 1000) {
    break;
  }
}

Compatibility table: http://kangax.github.io/es5-compat-table/es6/#For..of loops

Specification: http://wiki.ecmascript.org/doku.php?id=harmony:iterators

}

You want List::GetRange(firstIndex, count). See http://msdn.microsoft.com/en-us/library/21k0e39c.aspx

// I have a List called list
List sublist = list.GetRange(5, 5); // (gets elements 5,6,7,8,9)
List anotherSublist = list.GetRange(0, 4); // gets elements 0,1,2,3)

Is that what you're after?

If you're looking to delete the sublist items from the original list, you can then do:

// list is our original list
// sublist is our (newly created) sublist built from GetRange()
foreach (Type t in sublist)
{
    list.Remove(t);
}

Here is how its done in Angular 6

<li *ngFor="let user of userObservable ; first as isFirst">
   <span *ngIf="isFirst">default</span>
</li>

Note the change from let first = first to first as isFirst

java.time

The java.time framework built into Java 8 and later supplants both the old date-time classes bundled with the earliest versions of Java and the Joda-Time library. The java.time classes have been back-ported to Java 6 & 7 and to Android.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply an offset-from-UTC (a number of hours and possible minutes and seconds) to get an OffsetDateTime.

ZoneOffset offset = ZoneOffset.of( "-04:00" );
OffsetDateTime odt = OffsetDateTime.ofInstant( instant , offset );

Better yet is applying a full time zone which is an offset plus a set of rules for handling anomalies such as Daylight Saving Time (DST).

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Database

Hopefully the JDBC drivers will be updated to work directly with the java.time classes. Until then we must use the java.sql classes to move date-time values to/from the database. But limit your use of the java.sql classes to the chore of database transit. Do not use them for business logic. As part of the old date-time classes they are poorly designed, confusing, and troublesome.

Use new methods added to the old classes to convert to/from java.time. Look for to… and valueOf methods.

Use the java.sql.Timestamp class for date-time values.

java.sql.Timestamp ts = java.sql.Timestamp.valueOf( instant );

And going the other direction…

Instant instant = ts.toInstant();

For date-time data you virtually always want the TIMESTAMP WITH TIME ZONE data type rather than WITHOUT when designing your table columns in your database.

If you want to fetch particular element/node or tag in loop for e.g.

<p class="weekday" data-today="monday">Monday</p>
<p class="weekday" data-today="tuesday">Tuesday</p>
<p class="weekday" data-today="wednesday">Wednesday</p>
<p class="weekday" data-today="thursday">Thursday</p>

So, from above code loop is executed and we want particular field to select for that we have to use jQuery selection that can select only expecting element from above loop so, code will be

$('.weekdays:eq(n)');

e.g.

$('.weekdays:eq(0)');

as well as by other method

$('.weekday').find('p').first('.weekdays').next()/last()/prev();

but first method is more efficient when HTML <tag> has unique class name.

NOTE:Second method is use when their is no class name in target element or node.

for more follow https://api.jquery.com/eq/

I had the same problem. Solved using single quotes like this:

$ wget 'http://www.icerts.com/images/logo.jpg'

wget version in use:

$ wget --version

Yes, you can set cookie in the AJAX request in the server-side code just as you'd do for a normal request since the server cannot differentiate between a normal request or an AJAX request.

AJAX requests are just a special way of requesting to server, the server will need to respond back as in any HTTP request. In the response of the request you can add cookies.

date_default_timezone_set('Asia/Kolkata');

$curDateTime = date("Y-m-d H:i:s");
$myDate = date("Y-m-d H:i:s", strtotime("2018-06-26 16:15:33"));
if($myDate < $curDateTime){
    echo "active";exit;
}else{
    echo "inactive";exit;
}

Note that Internet Explorer from version 5 up to 8 will throw an error when trying to download a file served via https and the server sending Cache-Control: no-cache or Pragma: no-cache headers.

See http://support.microsoft.com/kb/812935/en-us

The use of Cache-Control: no-store and Pragma: private seems to be the closest thing which still works.

ALTERNATE WAY:

Click Developer Tools to inspect element. You may also use keyboard shortcuts, such as CtrlL+Shift+I, F12 (or Fn+F12), etc.

For joins, I strongly prefer query-syntax for all the details that are happily hidden (not the least of which are the transparent identifiers involved with the intermediate projections along the way that are apparent in the dot-syntax equivalent). However, you asked regarding Lambdas which I think you have everything you need - you just need to put it all together.

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new { ppc, c })
    .Select(m => new { 
        ProdId = m.ppc.p.Id, // or m.ppc.pc.ProdId
        CatId = m.c.CatId
        // other assignments
    });

If you need to, you can save the join into a local variable and reuse it later, however lacking other details to the contrary, I see no reason to introduce the local variable.

Also, you could throw the Select into the last lambda of the second Join (again, provided there are no other operations that depend on the join results) which would give:

var categorizedProducts = product
    .Join(productcategory, p => p.Id, pc => pc.ProdId, (p, pc) => new { p, pc })
    .Join(category, ppc => ppc.pc.CatId, c => c.Id, (ppc, c) => new {
        ProdId = ppc.p.Id, // or ppc.pc.ProdId
        CatId = c.CatId
        // other assignments
    });

...and making a last attempt to sell you on query syntax, this would look like this:

var categorizedProducts =
    from p in product
    join pc in productcategory on p.Id equals pc.ProdId
    join c in category on pc.CatId equals c.Id
    select new {
        ProdId = p.Id, // or pc.ProdId
        CatId = c.CatId
        // other assignments
    };

Your hands may be tied on whether query-syntax is available. I know some shops have such mandates - often based on the notion that query-syntax is somewhat more limited than dot-syntax. There are other reasons, like "why should I learn a second syntax if I can do everything and more in dot-syntax?" As this last part shows - there are details that query-syntax hides that can make it well worth embracing with the improvement to readability it brings: all those intermediate projections and identifiers you have to cook-up are happily not front-and-center-stage in the query-syntax version - they are background fluff. Off my soap-box now - anyhow, thanks for the question. :)

you can simply do that by using below single line of code

val arr = df.select("column").collect()(99)

You can do this also in kotlin like this:

    contentView.apply {
        // Set the content view to 0% opacity but visible, so that it is visible
        // (but fully transparent) during the animation.
        alpha = 0f
        visibility = View.VISIBLE

        // Animate the content view to 100% opacity, and clear any animation
        // listener set on the view.
        animate()
                .alpha(1f)
                .setDuration(resources.getInteger(android.R.integer.config_mediumAnimTime).toLong())
                .setListener(null)
    }

I keep this answer for "historic" purpose but don't recommend it anymore. See @Sidnicious' answer above and my Update 2.

Since it looks like a draw between callto and tel guys, I want to throw in a possible solution in the hope, that your comments will bring me back on the way of light ;-)

Using callto:, since most desktop clients will handle it:

<a href="callto:0123456789">call me</a>

Then, if the client is an iPhone, replace the links:

window.onload = function () {
  if (navigator.userAgent.match (/iPhone/i)) {
    var a = document.getElementsByTagName ("a");
    for (var i = 0; i < a.length; i++) {
      if (a[i].getAttribute ('href').search (/callto:/i) === 0) {
        a[i].setAttribute ('href', a[i].getAttribute ('href').replace (/^callto:/, "tel:"));
      }
    }
  }
};

Any objections against this solution? Should I preferably start from tel:?

I was having the same problem but wanted to minimize 3rd party dependencies (because this one-off script was to be executed by many users). My solution was to wrap a curl call and make sure that the exit code was 0. Worked like a charm.

This is often a firewall problem. The firewall log then shows dropped packets between 127.0.0.1: and 127.0.0.1:, where the latter is the port shown in the Browser to get no connection with. This means, that the connection between pgAdmin client (high_port_1) and pgAdmin server (high_port_2) is blocked. Check your firewall log and if you find dropped packets like described, adapt your firewall settings accordingly.

Gradients don't support transitions yet (although the current spec says they should support like gradient to like gradient transitions via interpolation.).

If you want a fade-in effect with a background gradient, you have to set an opacity on a container element and 'transition` the opacity.

(There have been some browser releases that supported transitions on gradients (e.g IE10. I tested gradient transitions in 2016 in IE and they seemed to work at the time, but my test code no longer works.)

Update: October 2018 Gradient transitions with un-prefixed new syntax [e.g. radial-gradient(...)]now confirmed to work (again?) on Microsoft Edge 17.17134. I don't know when this was added. Still not working on latest Firefox & Chrome / Windows 10.

You can specify multiple method signatures on the interface then have multiple method overloads on the class method:

interface INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter: number);
}

class MyNotificationService implements INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter?: number);
    error(message: string, param1?: (string|number), param2?: number) {
        var autoHideAfter: number,
            title: string;

        // example of mapping the parameters
        if (param2 != null) {
            autoHideAfter = param2;
            title = <string> param1;
        }
        else if (param1 != null) {
            if (typeof param1 === "string") {
                title = param1;
            }
            else {
                autoHideAfter = param1;
            }
        }

        // use message, autoHideAfter, and title here
    }
}

Now all these will work:

var service: INotificationService = new MyNotificationService();
service.error("My message");
service.error("My message", 1000);
service.error("My message", "My title");
service.error("My message", "My title", 1000);

...and the error method of INotificationService will have the following options:

I have implemented this validation. But you would be used code behind. It is too much easy and simplest way.

XAML: For name Validtion only enter character from A-Z and a-z.

<TextBox x:Name="first_name_texbox" PreviewTextInput="first_name_texbox_PreviewTextInput" >  </TextBox>

Code Behind.

private void first_name_texbox_PreviewTextInput ( object sender, TextCompositionEventArgs e )
{
    Regex regex = new Regex ( "[^a-zA-Z]+" );
    if ( regex.IsMatch ( first_name_texbox.Text ) )
    {
        MessageBox.Show("Invalid Input !");
    }
}

For Salary and ID validation, replace regex constructor passed value with [0-9]+. It means you can only enter number from 1 to infinite.

You can also define length with [0-9]{1,4}. It means you can only enter less then or equal to 4 digit number. This baracket means {at least,How many number}. By doing this you can define range of numbers in textbox.

May it help to others.

XAML:

Code Behind.

private void salary_texbox_PreviewTextInput ( object sender, TextCompositionEventArgs e )
{
    Regex regex = new Regex ( "[^0-9]+" );
    if ( regex.IsMatch ( salary_texbox.Text ) )
    {
        MessageBox.Show("Invalid Input !");
    }
}

What do you think about this approach?

with open(filename) as data:
    datalines = (line.rstrip('\r\n') for line in data)
    for line in datalines:
        ...do something awesome...

Generator expression avoids loading whole file into memory and with ensures closing the file

Since C++11, you can also use a lambda expression instead of defining a comparator struct:

auto comp = [](const string& a, const string& b) { return a.length() < b.length(); };
map<string, string, decltype(comp)> my_map(comp);

my_map["1"]      = "a";
my_map["three"]  = "b";
my_map["two"]    = "c";
my_map["fouuur"] = "d";

for(auto const &kv : my_map)
    cout << kv.first << endl;

Output:

1
two
three
fouuur

I'd like to repeat the final note of Georg's answer: When comparing by length you can only have one string of each length in the map as a key.

Code on Ideone

I don't have IE8 to test this out, but I'm pretty sure it should work:

<div class="screen">
   <!-- code -->
   <div class="innerdiv">
      text or other content
   </div>
</div>

and the css:

.screen{
position: relative;
}
.innerdiv {
position: absolute;
bottom: 0;
right: 0;
}

This should place the .innerdiv in the bottom-right corner of the .screen class. I hope this helps :)

The browser will execute the scripts in the order it finds them. If you call an external script, it will block the page until the script has been loaded and executed.

To test this fact:

// file: test.php
sleep(10);
die("alert('Done!');");

// HTML file:
<script type="text/javascript" src="test.php"></script>

Dynamically added scripts are executed as soon as they are appended to the document.

To test this fact:

<!DOCTYPE HTML>
<html>
<head>
    <title>Test</title>
</head>
<body>
    <script type="text/javascript">
        var s = document.createElement('script');
        s.type = "text/javascript";
        s.src = "link.js"; // file contains alert("hello!");
        document.body.appendChild(s);
        alert("appended");
    </script>
    <script type="text/javascript">
        alert("final");
    </script>
</body>
</html>

Order of alerts is "appended" -> "hello!" -> "final"

If in a script you attempt to access an element that hasn't been reached yet (example: <script>do something with #blah</script><div id="blah"></div>) then you will get an error.

Overall, yes you can include external scripts and then access their functions and variables, but only if you exit the current <script> tag and start a new one.

The solution as some previous answers has shown is to use typeof. the following is a code snippet In NodeJs,

    function startx() {
      console.log("startx function called.");
    }

 var fct= {};
 fct["/startx"] = startx;

if (typeof fct[/startx] === 'function') { //check if function then execute it
    fct[/startx]();
  }

I fixed it like this example.

$scope.myCalendar = new Date(myUnixDate*1000);
<input date-time ng-model="myCalendar" format="DD/MM/YYYY" />

$(this).parent()

Tree traversal is fun

$(this).parent().siblings(".something1");

$(this).parent().prev(); // if you always want the parent's previous sibling

$(this).parents(".box").children(".something1");

And much more ways, you might find these docs helpful.

Actually the main purpose of the RecyclerView is to compensate for ListView and ScrollView. Instead of doing what you're actually doing: Having a RecyclerView in a ScrollView, I would suggest having only a RecyclerView that can handle many types of children.

OK, going back to a previous commit in Git is quite easy...

Revert back without keeping the changes:

git reset --hard <commit>

Revert back with keeping the changes:

git reset --soft <commit>

Explanation: using git reset, you can reset to a specific state. It's common using it with a commit hash as you see above.

But as you see the difference is using the two flags --soft and --hard, by default git reset using --soft flag, but it's a good practice always using the flag, I explain each flag:

--soft

The default flag as explained, not need to provide it, does not change the working tree, but it adds all changed files ready to commit, so you go back to the commit status which changes to files get unstaged.

--hard

Be careful with this flag. It resets the working tree and all changes to tracked files and all will be gone!

I also created the image below that may happen in a real life working with Git:

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

This is because $pjs is an one-element-array of objects, so first you should access the array element, which is an object and then access its attributes.

echo $pjs[0]->player_name;

Actually dump result that you pasted tells it very clearly.

Wells are dropped from Bootstrap with the version 4.

You can use Cards instead of Wells.

Here is a quick example for how to use new Cards feature:

<div class="card card-inverse" style="background-color: #333; border-color: #333;">
  <div class="card-block">
    <h3 class="card-title">Card Title</h3>
    <p class="card-text">This text will be written on a grey background inside a Card.</p>
    <a href="#" class="btn btn-primary">This is a Button</a>
  </div>
</div>

Often your value occurs at multiple indices:

>>> myseries = pd.Series([0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 1, 1])
>>> myseries.index[myseries == 1]
Int64Index([3, 4, 5, 6, 10, 11], dtype='int64')

Try do something like this (the problem was that you trying to use MyBook.Worksheets, but MyBook is not a Workbook object, but string, containing workbook name. I've added new varible Set WB = ActiveWorkbook, so you can use WB.Worksheets instead MyBook.Worksheets):

Sub NewWBandPasteSpecialALLSheets()
   MyBook = ActiveWorkbook.Name ' Get name of this book
   Workbooks.Add ' Open a new workbook
   NewBook = ActiveWorkbook.Name ' Save name of new book

   Workbooks(MyBook).Activate ' Back to original book

   Set WB = ActiveWorkbook

   Dim SH As Worksheet

   For Each SH In WB.Worksheets

       SH.Range("WholePrintArea").Copy

       Workbooks(NewBook).Activate

       With SH.Range("A1")
        .PasteSpecial (xlPasteColumnWidths)
        .PasteSpecial (xlFormats)
        .PasteSpecial (xlValues)

       End With

     Next

End Sub

But your code doesn't do what you want: it doesen't copy something to a new WB. So, the code below do it for you:

Sub NewWBandPasteSpecialALLSheets()
   Dim wb As Workbook
   Dim wbNew As Workbook
   Dim sh As Worksheet
   Dim shNew As Worksheet

   Set wb = ThisWorkbook
   Workbooks.Add ' Open a new workbook
   Set wbNew = ActiveWorkbook

   On Error Resume Next

   For Each sh In wb.Worksheets
      sh.Range("WholePrintArea").Copy

      'add new sheet into new workbook with the same name
      With wbNew.Worksheets

          Set shNew = Nothing
          Set shNew = .Item(sh.Name)

          If shNew Is Nothing Then
              .Add After:=.Item(.Count)
              .Item(.Count).Name = sh.Name
              Set shNew = .Item(.Count)
          End If
      End With

      With shNew.Range("A1")
          .PasteSpecial (xlPasteColumnWidths)
          .PasteSpecial (xlFormats)
          .PasteSpecial (xlValues)
      End With
   Next
End Sub

You can also try out ctrl + alt + I even though you can also use l as well.

I had the EXACT same issue as the OP. My configuration and situation were identical. I finally narrowed it down to being an issue in WCFStorm after creating a service reference in a test project in Visual Studio and confirming that the service was working. In Storm you need to click on the "Config" settings option (NOT THE "Client Config"). After clicking on that, click on the "Security" tab on the dialog that pops up. Make sure "Authentication Type" is set to "None" (The default is "Windows Authentication"). Presto, it works! I always test out my methods in WCFStorm as I'm building them out, but have never tried using it to connect to one that has already been set up on SSL. Hope this helps someone!

Something like this?

SELECT  *
FROM    table1
WHERE   convert(varchar, column_datetime, 111) = '2008/08/14'

One method is:

File.Copy(oldFilePathWithFileName, newFilePathWithFileName);

Or you can use the FileInfo.CopyTo() method too something like this:

FileInfo file = new FileInfo(oldFilePathWithFileName);
file.CopyTo(newFilePathWithFileName);

Example:

File.Copy(@"c:\a.txt", @"c:\b.txt");

or

FileInfo file = new FileInfo(@"c:\a.txt");
file.CopyTo(@"c:\b.txt");

I found a simple way in com.google.common.primitives which is in the [Maven:com.google.guava:guava:12.0.1]

long newLong = Longs.fromByteArray(oldLongByteArray);
int newInt = Ints.fromByteArray(oldIntByteArray);

Have a nice try :)

the easiest way to do that in angular or angularjs without external modules or directives is using list and datalist HTML5. You just get a json and use ng-repeat for feeding the options in datalist. The json you can fetch it from ajax.

in this example:

• ctrl.query is the query that you enter when you type.
• ctrl.msg is the message that is showing in the placeholder
• ctrl.dataList is the json fetched

then you can add filters and orderby in the ng-reapet

!! list and datalist id must have the same name !!

 <input type="text" list="autocompleList" ng-model="ctrl.query" placeholder={{ctrl.msg}}>
<datalist id="autocompleList">
        <option ng-repeat="Ids in ctrl.dataList value={{Ids}}  >
</datalist>

UPDATE : is native HTML5 but be carreful with the type browser and version. check it out : https://caniuse.com/#search=datalist.

1. Use a single body parameter within the mailto string
2. Use %0D%0A as newline

The mailto URI Scheme is specified by by RFC2368 (July 1998) and RFC6068 (October 2010).
Below is an extract of section 5 of this last RFC:

[...] line breaks in the body of a message MUST be encoded with "%0D%0A".
Implementations MAY add a final line break to the body of a message even if there is no trailing "%0D%0A" in the body [...]

See also in section 6 the example from the same RFC:

<mailto:[email protected]?body=send%20current-issue%0D%0Asend%20index>

The above mailto body corresponds to:

send current-issue
send index

You have a truncated array representation. Let's look at a full example:

>>> a = np.zeros((2, 3, 4))
>>> a
array([[[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]],

       [[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]]])

Arrays in NumPy are printed as the word array followed by structure, similar to embedded Python lists. Let's create a similar list:

>>> l = [[[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]],

          [[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]]]

>>> l
[[[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]], 
 [[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]]]

The first level of this compound list l has exactly 2 elements, just as the first dimension of the array a (# of rows). Each of these elements is itself a list with 3 elements, which is equal to the second dimension of a (# of columns). Finally, the most nested lists have 4 elements each, same as the third dimension of a (depth/# of colors).

So you've got exactly the same structure (in terms of dimensions) as in Matlab, just printed in another way.

Some caveats:

1. Matlab stores data column by column ("Fortran order"), while NumPy by default stores them row by row ("C order"). This doesn't affect indexing, but may affect performance. For example, in Matlab efficient loop will be over columns (e.g. for n = 1:10 a(:, n) end), while in NumPy it's preferable to iterate over rows (e.g. for n in range(10): a[n, :] -- note n in the first position, not the last).

2. If you work with colored images in OpenCV, remember that:

   2.1. It stores images in BGR format and not RGB, like most Python libraries do.

   2.2. Most functions work on image coordinates (x, y), which are opposite to matrix coordinates (i, j).

Swift 3

The Swift 3 solution (based on Dima's answer) with UIView extension should be like this:

extension UIView {
    public func getSnapshotImage() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.bounds.size, self.isOpaque, 0)
        self.drawHierarchy(in: self.bounds, afterScreenUpdates: false)
        let snapshotImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return snapshotImage
    }
}

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

Another option is regex:

>>> import re
>>> re.sub("\n|\r", "", "Foo\n\rbar\n\rbaz\n\r")
'Foobarbaz'

Conceptually there are the two "domains" classes and interfaces. Inside these domains you are always extending, only a class implements an interface, which is kind of "crossing the border". So basically "extends" for interfaces mirrors the behavior for classes. At least I think this is the logic behind. It seems than not everybody agrees with this kind of logic (I find it a little bit contrived myself), and in fact there is no technical reason to have two different keywords at all.

I just repaired my NodeJS installation and it worked for me!

Go to Control Panel\All Control Panel Items\Programs and Features --> find NodeJS and choose option repair to repair it. Hope this helps.

Well if you know the basics behind them, it shouldn't be too hard.

Generally you create an array called "buckets" that contain the key and value, with an optional pointer to create a linked list.

When you access the hash table with a key, you process the key with a custom hash function which will return an integer. You then take the modulus of the result and that is the location of your array index or "bucket". Then you check the unhashed key with the stored key, and if it matches, then you found the right place.

Otherwise, you've had a "collision" and must crawl through the linked list and compare keys until you match. (note some implementations use a binary tree instead of linked list for collisions).

Check out this fast hash table implementation:

https://attractivechaos.wordpress.com/2009/09/29/khash-h/

This is part of code I made for IBAN validation. Feel free to use.

    static void Main(string[] args)
    {
        int modulo = 97;
        string input = Reverse("100020778788920323232343433");
        int result = 0;
        int lastRowValue = 1;

        for (int i = 0; i < input.Length; i++)
        {
            // Calculating the modulus of a large number Wikipedia http://en.wikipedia.org/wiki/International_Bank_Account_Number                                                                        
            if (i > 0)
            {
                lastRowValue = ModuloByDigits(lastRowValue, modulo);
            }
            result += lastRowValue * int.Parse(input[i].ToString());
        }
        result = result % modulo;
        Console.WriteLine(string.Format("Result: {0}", result));            
    }

    public static int ModuloByDigits(int previousValue, int modulo)
    {
        // Calculating the modulus of a large number Wikipedia http://en.wikipedia.org/wiki/International_Bank_Account_Number                        
        return ((previousValue * 10) % modulo);
    }
    public static string Reverse(string input)
    {
        char[] arr = input.ToCharArray();
        Array.Reverse(arr);
        return new string(arr);
    }

If, like me, you have MSYS_NO_PATHCONV = 1 configured as a user variable for Git Bash, this issue will be triggered. To workaround, you can either remove this variable or use a different shell (PowerShell) for npm.

You need to use setLayoutManager in the RecyclerView#onCreate() method. Before adding recyclerView to a view, it must have the LayoutManager set.

 private RecyclerView menuAsList;

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

    menuAsList = (RecyclerView) findViewById(R.id.recyclerView_mainMenu);
    menuAsList.setLayoutManager(new LinearLayoutManager(Home.this));

}

If you are using .net, you should use the InternalsVisibleToAttribute.

There are detailed notes on this that helped me completely, located here.

Jonathon Reinhart has already answered with the key bit, to edit /etc/gitlab/gitlab.rb, alter the external_url and then run sudo gitlab-ctl reconfigure; sudo gitlab-ctl restart

However I needed to go a bit further and docs I linked above explained it. So what I ended up with looks like:

external_url 'https://gitlab.toilethumor.com'
nginx['ssl_certificate'] = "/www/ssl/star_toilethumor.com-chained.crt"
nginx['ssl_certificate_key'] = "/www/ssl/star_toilethumor.com.key"
nginx['proxy_set_headers'] = {
 "X-Forwarded-Proto" => "http",
 "CUSTOM_HEADER" => "VALUE"
}

Above, I've explicitly declared where my SSL goodies are on this server. And that's of course followed by

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

Also, when you switch the omnibus package to https, the bundled nginx will only serve on port 443. Since all my stuff is reached via reverse proxy, this part was potentially significant.

As I went through this, I screwed something up and it helpful to find the actual nginx logs, this lead me there:

sudo gitlab-ctl tail nginx

Trivial (but working) solution:

echo -e "---------------------------- [UP]\r$PROC_NAME "

A nice solution without using interop:

As always, simply enable DoubleBuffered=true on your CustomControl. Then, if you have any containers like FlowLayoutPanel or TableLayoutPanel, derive a class from each of these types and in the constructors, enable double buffering. Now, simply use your derived Containers instead of the Windows.Forms Containers.

class TableLayoutPanel : System.Windows.Forms.TableLayoutPanel
{
    public TableLayoutPanel()
    {
        DoubleBuffered = true;
    }
}

class FlowLayoutPanel : System.Windows.Forms.FlowLayoutPanel
{
    public FlowLayoutPanel()
    {
        DoubleBuffered = true;
    }
}

When you type the FROM table those errors will disappear. Type FROM below what your typing then Intellisense will work and multi-part identifier will work.

A neat trick I discovered is that if you go to "Add existing...", you can drag the folder from the open dialog to your solution.

I have my Visual Studio to open in Admin Mode automatically, so this was a good workaround for me as I didn't want to have to undo that just to get this to work.

You can move your proxy authentication and ssl staff to soap handler

  port = new SomeService().getServicePort();
  Binding binding = ((BindingProvider) port).getBinding();
  binding.setHandlerChain(Collections.<Handler>singletonList(new ProxyHandler()));

This is my example, do all network ops

  class ProxyHandler implements SOAPHandler<SOAPMessageContext> {
    static class TrustAllHost implements HostnameVerifier {
      public boolean verify(String urlHostName, SSLSession session) {
        return true;
      }
    }

    static class TrustAllCert implements X509TrustManager {
      public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
      }

      public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
      }

      public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
      }
    }

    private SSLSocketFactory socketFactory;

    public SSLSocketFactory getSocketFactory() throws Exception {
      // just an example
      if (socketFactory == null) {
        SSLContext sc = SSLContext.getInstance("SSL");
        TrustManager[] trustAllCerts = new TrustManager[] { new TrustAllCert() };
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        socketFactory = sc.getSocketFactory();
      }

      return socketFactory;
    }

          http.disconnect();
      }
    }

    @Override public boolean handleFault(SOAPMessageContext context) {
      return false;
    }

    @Override public void close(MessageContext context) {
    }

    @Override public Set<QName> getHeaders() {
      return Collections.emptySet();
    }
  }

It use UrlConnection, you can use any library you want in handler. Have fun!

Your configuration should look similar to that. You may have to change <transport clientCredentialType="None" proxyCredentialType="None" /> depending on your needs for authentication. The config below doesn't require any authentication.

<bindings>
    <basicHttpBinding>
        <binding name="basicHttpBindingConfiguration">
            <security mode="Transport">
                <transport clientCredentialType="None" proxyCredentialType="None" />
            </security>
        </binding>       
    </basicHttpBinding>
</bindings>

<services>
    <service name="XXX">
        <endpoint
            name="AAA"
            address=""
            binding="basicHttpBinding"
            bindingConfiguration="basicHttpBindingConfiguration"
            contract="YourContract" />
    </service>
<services>

That will allow a WCF service with basicHttpBinding to use HTTPS.

Foreword

Starting with your table definition:

- UserID
- Fname
- Lname
- Email
- Password
- IV

Here are the changes:

1. The fields Fname, Lname and Email will be encrypted using a symmetric cipher, provided by OpenSSL,
2. The IV field will store the initialisation vector used for encryption. The storage requirements depend on the cipher and mode used; more about this later.
3. The Password field will be hashed using a one-way password hash,

Choosing the best encryption cipher and mode is beyond the scope of this answer, but the final choice affects the size of both the encryption key and initialisation vector; for this post we will be using AES-256-CBC which has a fixed block size of 16 bytes and a key size of either 16, 24 or 32 bytes.

Encryption key

A good encryption key is a binary blob that's generated from a reliable random number generator. The following example would be recommended (>= 5.3):

$key_size = 32; // 256 bits
$encryption_key = openssl_random_pseudo_bytes($key_size, $strong);
// $strong will be true if the key is crypto safe

This can be done once or multiple times (if you wish to create a chain of encryption keys). Keep these as private as possible.

IV

The initialisation vector adds randomness to the encryption and required for CBC mode. These values should be ideally be used only once (technically once per encryption key), so an update to any part of a row should regenerate it.

A function is provided to help you generate the IV:

$iv_size = 16; // 128 bits
$iv = openssl_random_pseudo_bytes($iv_size, $strong);

Example

Let's encrypt the name field, using the earlier $encryption_key and $iv; to do this, we have to pad our data to the block size:

function pkcs7_pad($data, $size)
{
    $length = $size - strlen($data) % $size;
    return $data . str_repeat(chr($length), $length);
}

$name = 'Jack';
$enc_name = openssl_encrypt(
    pkcs7_pad($name, 16), // padded data
    'AES-256-CBC',        // cipher and mode
    $encryption_key,      // secret key
    0,                    // options (not used)
    $iv                   // initialisation vector
);

Storage requirements

The encrypted output, like the IV, is binary; storing these values in a database can be accomplished by using designated column types such as BINARY or VARBINARY.

The output value, like the IV, is binary; to store those values in MySQL, consider using BINARY or VARBINARY columns. If this is not an option, you can also convert the binary data into a textual representation using base64_encode() or bin2hex(), doing so requires between 33% to 100% more storage space.

Decryption

Decryption of the stored values is similar:

function pkcs7_unpad($data)
{
    return substr($data, 0, -ord($data[strlen($data) - 1]));
}

$row = $result->fetch(PDO::FETCH_ASSOC); // read from database result
// $enc_name = base64_decode($row['Name']);
// $enc_name = hex2bin($row['Name']);
$enc_name = $row['Name'];
// $iv = base64_decode($row['IV']);
// $iv = hex2bin($row['IV']);
$iv = $row['IV'];

$name = pkcs7_unpad(openssl_decrypt(
    $enc_name,
    'AES-256-CBC',
    $encryption_key,
    0,
    $iv
));

Authenticated encryption

You can further improve the integrity of the generated cipher text by appending a signature that's generated from a secret key (different from the encryption key) and the cipher text. Before the cipher text is decrypted, the signature is first verified (preferably with a constant-time comparison method).

Example

// generate once, keep safe
$auth_key = openssl_random_pseudo_bytes(32, $strong);

// authentication
$auth = hash_hmac('sha256', $enc_name, $auth_key, true);
$auth_enc_name = $auth . $enc_name;

// verification
$auth = substr($auth_enc_name, 0, 32);
$enc_name = substr($auth_enc_name, 32);
$actual_auth = hash_hmac('sha256', $enc_name, $auth_key, true);

if (hash_equals($auth, $actual_auth)) {
    // perform decryption
}

Hashing

Storing a reversible password in your database must be avoided as much as possible; you only wish to verify the password rather than knowing its contents. If a user loses their password, it's better to allow them to reset it rather than sending them their original one (make sure that password reset can only be done for a limited time).

Applying a hash function is a one-way operation; afterwards it can be safely used for verification without revealing the original data; for passwords, a brute force method is a feasible approach to uncover it due to its relatively short length and poor password choices of many people.

Hashing algorithms such as MD5 or SHA1 were made to verify file contents against a known hash value. They're greatly optimized to make this verification as fast as possible while still being accurate. Given their relatively limited output space it was easy to build a database with known passwords and their respective hash outputs, the rainbow tables.

Adding a salt to the password before hashing it would render a rainbow table useless, but recent hardware advancements made brute force lookups a viable approach. That's why you need a hashing algorithm that's deliberately slow and simply impossible to optimize. It should also be able to increase the load for faster hardware without affecting the ability to verify existing password hashes to make it future proof.

Currently there are two popular choices available:

1. PBKDF2 (Password Based Key Derivation Function v2)
2. bcrypt (aka Blowfish)

This answer will use an example with bcrypt.

Generation

A password hash can be generated like this:

$password = 'my password';
$random = openssl_random_pseudo_bytes(18);
$salt = sprintf('$2y$%02d$%s',
    13, // 2^n cost factor
    substr(strtr(base64_encode($random), '+', '.'), 0, 22)
);

$hash = crypt($password, $salt);

The salt is generated with openssl_random_pseudo_bytes() to form a random blob of data which is then run through base64_encode() and strtr() to match the required alphabet of [A-Za-z0-9/.].

The crypt() function performs the hashing based on the algorithm ($2y$ for Blowfish), the cost factor (a factor of 13 takes roughly 0.40s on a 3GHz machine) and the salt of 22 characters.

Validation

Once you have fetched the row containing the user information, you validate the password in this manner:

$given_password = $_POST['password']; // the submitted password
$db_hash = $row['Password']; // field with the password hash

$given_hash = crypt($given_password, $db_hash);

if (isEqual($given_hash, $db_hash)) {
    // user password verified
}

// constant time string compare
function isEqual($str1, $str2)
{
    $n1 = strlen($str1);
    if (strlen($str2) != $n1) {
        return false;
    }
    for ($i = 0, $diff = 0; $i != $n1; ++$i) {
        $diff |= ord($str1[$i]) ^ ord($str2[$i]);
    }
    return !$diff;
}

To verify a password, you call crypt() again but you pass the previously calculated hash as the salt value. The return value yields the same hash if the given password matches the hash. To verify the hash, it's often recommended to use a constant-time comparison function to avoid timing attacks.

Password hashing with PHP 5.5

PHP 5.5 introduced the password hashing functions that you can use to simplify the above method of hashing:

$hash = password_hash($password, PASSWORD_BCRYPT, ['cost' => 13]);

And verifying:

if (password_verify($given_password, $db_hash)) {
    // password valid
}

As someone more experienced with Oracle DB, I was concerned about this limit too. I carried out a performance test for a query with ~10'000 parameters in an IN-list, fetching prime numbers up to 100'000 from a table with the first 100'000 integers by actually listing all the prime numbers as query parameters.

My results indicate that you need not worry about overloading the query plan optimizer or getting plans without index usage, since it will transform the query to use = ANY({...}::integer[]) where it can leverage indices as expected:

-- prepare statement, runs instantaneous:
PREPARE hugeplan (integer, integer, integer, ...) AS
SELECT *
FROM primes
WHERE n IN ($1, $2, $3, ..., $9592);

-- fetch the prime numbers:
EXECUTE hugeplan(2, 3, 5, ..., 99991);

-- EXPLAIN ANALYZE output for the EXECUTE:
"Index Scan using n_idx on primes  (cost=0.42..9750.77 rows=9592 width=5) (actual time=0.024..15.268 rows=9592 loops=1)"
"  Index Cond: (n = ANY ('{2,3,5,7, (...)"
"Execution time: 16.063 ms"

-- setup, should you care:
CREATE TABLE public.primes
(
  n integer NOT NULL,
  prime boolean,
  CONSTRAINT n_idx PRIMARY KEY (n)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE public.primes
  OWNER TO postgres;

INSERT INTO public.primes
SELECT generate_series(1,100000);

However, this (rather old) thread on the pgsql-hackers mailing list indicates that there is still a non-negligible cost in planning such queries, so take my word with a grain of salt.

A Quote from : iPhone Developer Program (~8MB PDF)

A provisioning profile is a collection of digital entities that uniquely ties developers and devices to an authorized iPhone Development Team and enables a device to be used for testing. A Development Provisioning Profile must be installed on each device on which you wish to run your application code. Each Development Provisioning Profile will contain a set of iPhone Development Certificates, Unique Device Identifiers and an App ID. Devices specified within the provisioning profile can be used for testing only by those individuals whose iPhone Development Certificates are included in the profile. A single device can contain multiple provisioning profiles.

No, it doesn't, see: R Language Definition: Operators

enum is used to assign value to enum elements which cannot be done in struct. So everytime instead of accessing the complete variable we can do it by the value we assign to the variables in enum. By default it starts with 0 assignment but we can assign it any value and the next variable in enum will be assigned a value the previous value +1.

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

char **options[2][100];

declares a size-2 array of size-100 arrays of pointers to pointers to char. You'll want to remove one *. You'll also want to put your string literals in double quotes.

PictureBox.Image is a property, not a method. You can set it like this:

PictureBox1.Image = System.Drawing.Image.FromFile(dlg.FileName);

Simple answer - whenever your SQL is not altering data, and you have a query that might interfere with other activity (via locking).

It's worth considering for any queries used for reports, especially if the query takes more than, say, 1 second.

It's especially useful if you have OLAP-type reports you're running against an OLTP database.

The first question to ask, though, is "why am I worrying about this?" ln my experience, fudging the default locking behavior often takes place when someone is in "try anything" mode and this is one case where unexpected consequences are not unlikely. Too often it's a case of premature optimization and can too easily get left embedded in an application "just in case." It's important to understand why you're doing it, what problem it solves, and whether you actually have the problem.

A simple addClass and removeClass will do the trick on what you need..

$('#change').on('click', function() { 
  $('div').each(function() { 
    if($(this).hasClass('active')) { 
        $(this).removeClass('active');
    } else { 
        $(this).addClass('active');
    }
});

});

I recommend you to learn jquery first before using.

For future readers, here is an elegant solution(5x5):

var matrix = [[Int]](repeating: [Int](repeating: 0, count: 5), count: 5)

and a dynamic approach:

var matrix = [[Int]]() // creates an empty matrix
var row = [Int]() // fill this row
matrix.append(row) // add this row

I like jQuery SVG library very much. It helps me every time I need to manipulate with SVG. It really facilitate the work with SVG from JavaScript.

public class TrackingSystemApplication {

    public static void main(String[] args) {
        SpringApplication.run(TrackingSystemApplication.class, args);
    }

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("http://localhost:4200").allowedMethods("PUT", "DELETE",
                        "GET", "POST");
            }
        };
    }

}

Try this ...

Dim r as Range
Dim x as Integer

For x = 5000 to 4 step -1 '---> or change as you want //Thanx 4 KazJaw

  set r = range("E" & format(x))
  if ucase(r.Value) = "NONE" then
    Rows(x).EntireRow.Delete
  end if

Probably you are facing problem when a download request is made by the maybe_download function call in base.py file.

There is a conflict in the permissions of the temporary files and I myself couldn't work out a way to change the permissions, but was able to work around the problem.

Do the following...

• Download the four .gz files of the MNIST data set from the link ( http://yann.lecun.com/exdb/mnist/ )
• Then make a folder names MNIST_data (or your choice in your working directory/ site packages folder in the tensorflow\examples folder).
• Directly copy paste the files into the folder.
• Copy the address of the folder (it probably will be ( C:\Python\Python35\Lib\site-packages\tensorflow\examples\tutorials\mnist\MNIST_data ))
• Change the "\" to "/" as "\" is used for escape characters, to access the folder locations.
• Lastly, if you are following the tutorials, your call function would be ( mnist = input_data.read_data_sets("MNIST_data/", one_hot=True) ) ; change the "MNIST_data/" parameter to your folder location. As in my case would be ( mnist = input_data.read_data_sets("C:/Python/Python35/Lib/site-packages/tensorflow/examples/tutorials/mnist/MNIST_data", one_hot=True) )

Then it's all done. Hope it works for you.

You can escape the square brackets with double backslashes like this:

$('input[name="pages_title\\[\\]"]')

Don't go there. As a long term Mac developer, I can assure you, no solution is really working well. I tried so many solutions, but they are all not too good. I think the problem is that Apple does not really document the meta data format for the necessary data.

Here's how I'm doing it for a long time, very successfully:

1. Create a new DMG, writeable(!), big enough to hold the expected binary and extra files like readme (sparse might work).

2. Mount the DMG and give it a layout manually in Finder or with whatever tools suits you for doing that (see FileStorm link at the bottom for a good tool). The background image is usually an image we put into a hidden folder (".something") on the DMG. Put a copy of your app there (any version, even outdated one will do). Copy other files (aliases, readme, etc.) you want there, again, outdated versions will do just fine. Make sure icons have the right sizes and positions (IOW, layout the DMG the way you want it to be).

3. Unmount the DMG again, all settings should be stored by now.

4. Write a create DMG script, that works as follows:

   • It copies the DMG, so the original one is never touched again.
   • It mounts the copy.
   • It replaces all files with the most up to date ones (e.g. latest app after build). You can simply use mv or ditto for that on command line. Note, when you replace a file like that, the icon will stay the same, the position will stay the same, everything but the file (or directory) content stays the same (at least with ditto, which we usually use for that task). You can of course also replace the background image with another one (just make sure it has the same dimensions).
   • After replacing the files, make the script unmount the DMG copy again.
   • Finally call hdiutil to convert the writable, to a compressed (and such not writable) DMG.

This method may not sound optimal, but trust me, it works really well in practice. You can put the original DMG (DMG template) even under version control (e.g. SVN), so if you ever accidentally change/destroy it, you can just go back to a revision where it was still okay. You can add the DMG template to your Xcode project, together with all other files that belong onto the DMG (readme, URL file, background image), all under version control and then create a target (e.g. external target named "Create DMG") and there run the DMG script of above and add your old main target as dependent target. You can access files in the Xcode tree using ${SRCROOT} in the script (is always the source root of your product) and you can access build products by using ${BUILT_PRODUCTS_DIR} (is always the directory where Xcode creates the build results).

Result: Actually Xcode can produce the DMG at the end of the build. A DMG that is ready to release. Not only you can create a relase DMG pretty easy that way, you can actually do so in an automated process (on a headless server if you like), using xcodebuild from command line (automated nightly builds for example).

Regarding the initial layout of the template, FileStorm is a good tool for doing it. It is commercial, but very powerful and easy to use. The normal version is less than $20, so it is really affordable. Maybe one can automate FileStorm to create a DMG (e.g. via AppleScript), never tried that, but once you have found the perfect template DMG, it's really easy to update it for every release.
