You would need to restart the Postgresql Server.

If you are using ubuntu you can restart Postgresql by following command

sudo service postgresql restart

I have tried all solutions but only works below command

pip install psycopg2-binary

Another option is to use Homebrew which works on Linux and macOS to install just the supporting libraries:

brew install libpq

then

brew link libpq --force

(the --force option is required because it conflicts with the postgres formula.)

I think I found a simple solution after a lot of irritation :

if elem in string_list:
    counter = 0
    elem_pos = []
    for i in string_list:
        if i == elem:
            elem_pos.append(counter)
        counter = counter + 1
    print(elem_pos)

This prints a list giving you the indexes of a specific element ("elem")

Using @extend is a fine solution, but be aware that the compiled css will break up the class definition. Any classes that extends the same placeholder will be grouped together and the rules that aren't extended in the class will be in a separate definition. If several classes become extended, it can become unruly to look up a selector in the compiled css or the dev tools. Whereas a mixin will duplicate the mixin code and add any additional styles.

You can see the difference between @extend and @mixin in this sassmeister

Here's a copy/paste-able extension method for IEnumerable

public static class EnumerableExtensions
{
    /// <summary>
    /// Searches for an element that matches the conditions defined by the specified predicate,
    /// and returns the zero-based index of the first occurrence within the entire <see cref="IEnumerable{T}"/>.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="list">The list.</param>
    /// <param name="predicate">The predicate.</param>
    /// <returns>
    /// The zero-based index of the first occurrence of an element that matches the conditions defined by <paramref name="predicate"/>, if found; otherwise it'll throw.
    /// </returns>
    public static int FindIndex<T>(this IEnumerable<T> list, Func<T, bool> predicate)
    {
        var idx = list.Select((value, index) => new {value, index}).Where(x => predicate(x.value)).Select(x => x.index).First();
        return idx;
    }
}

Enjoy.

This is indeed a bit of an annoying problem. For python 2.x.x you use:

cv2.CV_FONT_HERSHEY_SIMPLEX

and for Python 3.x.x:

cv2.FONT_HERSHEY_SIMPLEX

I recommend using a autocomplete environment(pyscripter or scipy for example). If you lookup example code, make sure they use the same version of Python(if they don't make sure you change the code).

this function worked for me

<?php

function everything_in_tags($string, $tagname)
{
    $pattern = "#<\s*?$tagname\b[^>]*>(.*?)</$tagname\b[^>]*>#s";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}

?>

You can use:

String.prototype.replaceAll = function(search, replace) {
if (replace === undefined) {
    return this.toString();
}
return this.split(search).join(replace);
}

<?php echo substr($string, 0, strlen($string) - 3); ?>

Remove your file or your path using before execute the command do a bk of your changes

sudo rm -r /path/to/dir/

after :

svn up and commit or delete 

Put the table in a container element that has

overflow:scroll; max-width:95vw;

or make the table fit to the screen and overflow:scroll all table cells.

If that's all what you want to do, you don't need to convert it into an array. You can just access it as:

string myData=yourDataTable.Rows[0][1].ToString();//Gives you USA

@gbtimmon's answer is great, but way, way too complicated. I've simplified his code as much as I could.

#hide:target + #show,
#hide:target ~ #answer {

<a href="#/" id="show">Hide</a>
<div id="answer"><p>Answer</p></div>

The PrintWriter class can actually create the file for you.

This example works in JDK 1.7+.

// This will create the file.txt in your working directory.

PrintWriter printWriter = null;

try {

    printWriter = new PrintWriter("file.txt", "UTF-8");
    // The second parameter determines the encoding. It can be
    // any valid encoding, but I used UTF-8 as an example.

} catch (FileNotFoundException | UnsupportedEncodingException error) {
    error.printStackTrace();
}

printWriter.println("Write whatever you like in your file.txt");

// Make sure to close the printWriter object otherwise nothing
// will be written to your file.txt and it will be blank.
printWriter.close();

For a list of valid encodings, see the documentation.

Alternatively, you can just pass the file path to the PrintWriter class without declaring the encoding.

Include in the GROUP BY clause all SELECT expressions that are not group function arguments.

$width = 10;

$a = preg_replace ("~^(.{{$width}})(.+)~", '\\1…', $a);

or with wordwrap

$a = preg_replace ("~^(.{1,${width}}\b)(.+)~", '\\1…', $a);

There are quite a few options that can be used: (both tested).

Here are two ways.

header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');

or: (note the escaped double-quotes). The same need to be use when assigning a name to it.

<?php

echo "<iframe src=\"file.pdf\" width=\"100%\" style=\"height:100%\"></iframe>";

?>

I.e.: name="myiframe" id="myiframe"

would need to be changed to:

name=\"myiframe\" id=\"myiframe\" inside PHP.

Be sure to have a look at: this answer on SO for more options on the subject.

Footnote: There are known issues when trying to view PDF files in Windows 8. Installing Adobe Acrobat Reader is a better method to view these types of documents if no browser plug-ins are installed.

When your code does the following:

1. Checks the current user has permission to do something.
2. Carries out the action that needs the entitlements checked in 1.

You run the risk that the permissions change between 1 and 2 because you can't predict what else will be happening on the system at runtime. Therefore, your code should handle the situation where an UnauthorisedAccessException is thrown even if you have previously checked permissions.

Note that the SecurityManager class is used to check CAS permissions and doesn't actually check with the OS whether the current user has write access to the specified location (through ACLs and ACEs). As such, IsGranted will always return true for locally running applications.

Example (derived from Josh's example):

//1. Provide early notification that the user does not have permission to write.
FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, filename);
if(!SecurityManager.IsGranted(writePermission))
{
    //No permission. 
    //Either throw an exception so this can be handled by a calling function
    //or inform the user that they do not have permission to write to the folder and return.
}

//2. Attempt the action but handle permission changes.
try
{
    using (FileStream fstream = new FileStream(filename, FileMode.Create))
    using (TextWriter writer = new StreamWriter(fstream))
    {
        writer.WriteLine("sometext");
    }
}
catch (UnauthorizedAccessException ex)
{
    //No permission. 
    //Either throw an exception so this can be handled by a calling function
    //or inform the user that they do not have permission to write to the folder and return.
}

It's tricky and not recommended to try to programatically calculate the effective permissions from the folder based on the raw ACLs (which are all that are available through the System.Security.AccessControl classes). Other answers on Stack Overflow and the wider web recommend trying to carry out the action to know whether permission is allowed. This post sums up what's required to implement the permission calculation and should be enough to put you off from doing this.

List<T> for strongly typed one, or ArrayList if you have .NET 1.1 or love to cast variables.

The following worked for me:

hdiutil detach <path to sshfs mount>

Example:

hdiutil detach /Users/user1/sshfs

One can also locate the volume created by sshfs in Finder, right-click, and select Eject. Which is, to the best of my knowledge, the GUI version of the above command.

If in the folder with your project you created a file with the name "datetime.py"

Here is a solution that doesn't require "spanCount" (number of columns) I use it because I use GridAutofitLayoutManager(calculates the number of columns according to the required cell size)

(beware that this will only work on GridLayoutManager)

public class GridSpacesItemDecoration extends RecyclerView.ItemDecoration {
    private final boolean includeEdge;
    private int spacing;


    public GridSpacesItemDecoration(int spacing, boolean includeEdge) {
        this.spacing = spacing;
        this.includeEdge = includeEdge;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        if (parent.getLayoutManager() instanceof GridLayoutManager) {
            GridLayoutManager layoutManager = (GridLayoutManager)parent.getLayoutManager();
            int spanCount = layoutManager.getSpanCount();
            int position = parent.getChildAdapterPosition(view); // item position
            int column = position % spanCount; // item column

            if (includeEdge) {
                outRect.left = spacing - column * spacing / spanCount; // spacing - column * ((1f / spanCount) * spacing)
                outRect.right = (column + 1) * spacing / spanCount; // (column + 1) * ((1f / spanCount) * spacing)

                if (position < spanCount) { // top edge
                    outRect.top = spacing;
                }
                outRect.bottom = spacing; // item bottom
            } else {
                outRect.left = column * spacing / spanCount; // column * ((1f / spanCount) * spacing)
                outRect.right = spacing - (column + 1) * spacing / spanCount; // spacing - (column + 1) * ((1f /    spanCount) * spacing)
                if (position >= spanCount) {
                    outRect.top = spacing; // item top
                }
            }

        }

    }
}

Here is the GridAutofitLayoutManager is anyone is interested:

public class GridAutofitLayoutManager extends GridLayoutManager {
    private int mColumnWidth;
    private boolean mColumnWidthChanged = true;

    public GridAutofitLayoutManager(Context context, int columnWidth)
    {
        /* Initially set spanCount to 1, will be changed automatically later. */
        super(context, 1);
        setColumnWidth(checkedColumnWidth(context, columnWidth));
    }

    public GridAutofitLayoutManager(Context context,int unit, int columnWidth)
    {
        /* Initially set spanCount to 1, will be changed automatically later. */
        super(context, 1);
        int pixColumnWidth = (int) TypedValue.applyDimension(unit, columnWidth, context.getResources().getDisplayMetrics());
        setColumnWidth(checkedColumnWidth(context, pixColumnWidth));
    }

    public GridAutofitLayoutManager(Context context, int columnWidth, int orientation, boolean reverseLayout)
    {
        /* Initially set spanCount to 1, will be changed automatically later. */
        super(context, 1, orientation, reverseLayout);
        setColumnWidth(checkedColumnWidth(context, columnWidth));
    }

    private int checkedColumnWidth(Context context, int columnWidth)
    {
        if (columnWidth <= 0)
        {
            /* Set default columnWidth value (48dp here). It is better to move this constant
            to static constant on top, but we need context to convert it to dp, so can't really
            do so. */
            columnWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48,
                    context.getResources().getDisplayMetrics());
        }
        return columnWidth;
    }

    public void setColumnWidth(int newColumnWidth)
    {
        if (newColumnWidth > 0 && newColumnWidth != mColumnWidth)
        {
            mColumnWidth = newColumnWidth;
            mColumnWidthChanged = true;
        }
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state)
    {
        int width = getWidth();
        int height = getHeight();
        if (mColumnWidthChanged && mColumnWidth > 0 && width > 0 && height > 0)
        {
            int totalSpace;
            if (getOrientation() == VERTICAL)
            {
                totalSpace = width - getPaddingRight() - getPaddingLeft();
            }
            else
            {
                totalSpace = height - getPaddingTop() - getPaddingBottom();
            }
            int spanCount = Math.max(1, totalSpace / mColumnWidth);
            setSpanCount(spanCount);

            mColumnWidthChanged = false;
        }
        super.onLayoutChildren(recycler, state);
    }
}

Finally:

mDevicePhotosView.setLayoutManager(new GridAutofitLayoutManager(getContext(), getResources().getDimensionPixelSize(R.dimen.item_size)));
mDevicePhotosView.addItemDecoration(new GridSpacesItemDecoration(Util.dpToPx(getContext(), 2),true));

Java's String.format works like so:

1. it parses the format string, exploding into a list of format chunks
2. it iterates the format chunks, rendering into a StringBuilder, which is basically an array that resizes itself as necessary, by copying into a new array. this is necessary because we don't yet know how large to allocate the final String
3. StringBuilder.toString() copies his internal buffer into a new String

if the final destination for this data is a stream (e.g. rendering a webpage or writing to a file), you can assemble the format chunks directly into your stream:

new PrintStream(outputStream, autoFlush, encoding).format("hello {0}", "world");

I speculate that the optimizer will optimize away the format string processing. If so, you're left with equivalent amortized performance to manually unrolling your String.format into a StringBuilder.

just use the core https module with the https.request function. Example for a POST request (GET would be similar):

var https = require('https');

var options = {
  host: 'www.google.com',
  port: 443,
  path: '/upload',
  method: 'POST'
};

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

You can do it like this:

declare @results varchar(500)

select @results = coalesce(@results + ',', '') +  convert(varchar(12),col)

select @results as results

My two cents on Stream. I think it's better to use

IntStream.generate(i -> MyClass.contruct())
         .limit(INT_SIZE)
         .collect(Collectors.toList());

with the flexibility to put any initial values.

Old, but this will do what you're after without need for jquery. The hidden overflow gets rid of the scrollbar, and the javascript makes it the right size.

<select multiple='multiple' id='select' style='overflow:hidden'>
<option value='foo'>foo</option>
<option value='bar'>bar</option>
<option value='abc'>abc</option>
<option value='def'>def</option>
<option value='xyz'>xyz</option>
</select>

And just a tiny amount of javascript

var select = document.getElementById('select');
select.size = select.length;

There are few steps to be followed (For Windows)

1. Open Git Bash and generate ssh key Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

   This creates a new ssh key, using the provided email as a label.

   Generating public/private rsa key pair.

   When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   Enter a file in which to save the key (/c/Users/you/.ssh/id_rsa):[Press enter]

   At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

   Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]

2. Add the key to SSH Agent

   Type the following in Git Bash (99999 is just an example) to see agent is up and running. eval $(ssh-agent -s) Agent pid 99999

   then type this.

   ssh-add ~/.ssh/id_rsa

   then Copy the SSH key to your clipboard using this command

   clip < ~/.ssh/id_rsa.pub

3. Add the SSH Key to the Git Account

   In GitHib site, click on the image on top right corner, and select settings. In the subsequent page, click SSH and GPG keys option. This will open up the SSH key page. Click on the New SSH key. In the "Title" field, add a descriptive label for the new key. Paste your key into the "Key" field.

4. Clone the Repository

   Open VS Code (or any IDE/CLI which has command prompt etc.). Go to the directory in which you want to clone, using cd commands, and type the below line. git config --global github.user yourGitUserName git config --global user.email your_email git clone [email protected]:yourGitUserName/YourRepoName.git

https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/

The only thing that worked for me:

g.drawOval((getWidth()-200)/2,(getHeight()-200)/2, 200, 200);    

The &nKByte creates a temporary value, which cannot be bound to a reference to non-const.

You could change void test(float *&x) to void test(float * const &x) or you could just drop the pointer altogether and use void test(float &x); /*...*/ test(nKByte);.

With influx, you can only delete by time

For example, the following are invalid:

#Wrong
DELETE FROM foo WHERE time < '2014-06-30' and duration > 1000 #Can't delete if where clause has non time entity

This is how I was able to delete the data

DELETE FROM foo WHERE time > '2014-06-30' and time < '2014-06-30 15:16:01'

Update: this worked on influx 8. Supposedly it doesn't work on influx 9

1. Modify the definition of the function check_me as::

    function check_me(ev) {
   

2. Now you can access the methods and parameters of the event, in your case:

    ev.preventDefault();
   

3. Then, you have to pass the parameter on the onclick in the inline call::

    <button type="button" onclick="check_me(event);">Click Me!</button>
   

A useful link to understand this.

Full example:

<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
    </script>
  </head>
  <body>
    <button type="button" onclick="check_me(event);">Click Me!</button>
  </body>
</html>

Alternatives (best practices):

Although the above is the direct answer to the question (passing an event object to an inline event), there are other ways of handling events that keep the logic separated from the presentation

A. Using addEventListener:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
      
      <!-- add the event to the button identified #my_button -->
      document.getElementById("my_button").addEventListener("click", check_me);
    </script>
  </body>
</html>

B. Isolating Javascript:

Both of the above solutions are fine for a small project, or a hackish quick and dirty solution, but for bigger projects, it is better to keep the HTML separated from the Javascript.

Just put this two files in the same folder:

• example.html:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript" src="example.js"></script>
  </body>
</html>

• example.js:

function check_me(ev) {
    ev.preventDefault();
    alert("Hello World!")
}
document.getElementById("my_button").addEventListener("click", check_me);

Another option is set this value "tcp_keepalives_idle". Check more in documentation https://www.postgresql.org/docs/10/runtime-config-connection.html.

Change Column Name/Type/Position/Comment:

ALTER TABLE table_name CHANGE [COLUMN] col_old_name col_new_name column_type [COMMENT col_comment] [FIRST|AFTER column_name]

Example:

CREATE TABLE test_change (a int, b int, c int);

// will change column a's name to a1
ALTER TABLE test_change CHANGE a a1 INT;

Borrowing @jgauffin answer as an HtmlHelper extension:

public static class HtmlHelperExtensions

        ViewDataDictionary viewData,

As well as using lapply or some other looping construct in R you could merge your CSV files into one file.

In Unix, if the files had no headers, then its as easy as:

cat *.csv > all.csv

or if there are headers, and you can find a string that matches headers and only headers (ie suppose header lines all start with "Age"), you'd do:

cat *.csv | grep -v ^Age > all.csv

I think in Windows you could do this with COPY and SEARCH (or FIND or something) from the DOS command box, but why not install cygwin and get the power of the Unix command shell?

I think the simple way is to use DateOffset from Pandas like so:

import pandas as pd
date_1 = pd.to_datetime("2013-03-31", format="%Y-%m-%d") - pd.DateOffset(months=1)

The result will be a Timestamp object

I caution against using the command

setx PATH "%PATH%;C:\Something\bin"

to modify the PATH variable because of a "feature" of its implementation. On many (most?) installations these days the variable will be lengthy - setx will truncate the stored string to 1024 bytes, potentially corrupting the PATH (see the discussion here).

The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever.

Smoke Testing

1. Smoke testing is a wide approach where all areas of the software application are tested without getting into too deep

2. The test cases for smoke testing of the software can be either manual or automated

3. Smoke testing is done to ensure whether the main functions of the software application are working or not. During smoke testing of the software, we do not go into finer details.

4. Smoke testing of the software application is done to check whether the build can be accepted for through software testing

5. This testing is performed by the developers or testers

6. Smoke testing exercises the entire system from end to end

7. Smoke testing is like General Health Check Up

8. Smoke testing is usually documented or scripted

Santy Testing

1. Sanity software testing is a narrow regression testing with a focus on one or a small set of areas of functionality of the software application.

2. Sanity test is generally without test scripts or test cases.

3. Sanity testing is a cursory software testing type. It is done whenever a quick round of software testing can prove that the software application is functioning according to business / functional requirements.

4. Sanity testing of the software is to ensure whether the requirements are met or not.

5. Sanity testing is usually performed by testers

6. Sanity testing exercises only the particular component of the entire system

7. Sanity Testing is like specialized health check up

8. Sanity testing is usually not documented and is unscripted

You should add parse_dates=True, or parse_dates=['column name'] when reading, thats usually enough to magically parse it. But there are always weird formats which need to be defined manually. In such a case you can also add a date parser function, which is the most flexible way possible.

Suppose you have a column 'datetime' with your string, then:

from datetime import datetime
dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')

df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)

This way you can even combine multiple columns into a single datetime column, this merges a 'date' and a 'time' column into a single 'datetime' column:

dateparse = lambda x: datetime.strptime(x, '%Y-%m-%d %H:%M:%S')

df = pd.read_csv(infile, parse_dates={'datetime': ['date', 'time']}, date_parser=dateparse)

You can find directives (i.e. the letters to be used for different formats) for strptime and strftime in this page.

Try Using JOptionPane or Swt Shell .

using the top answer produces a warning about making changes to a copy of a df slice. Assuming that you have other columns, a better way to do this is to pass a dictionary:
df.fillna({'A': 'NA', 'B': 'NA'}, inplace=True)

You could try to use GraphicsMagick Image Processing System with im4java as a comand-line interface for Java.

There are a lot of advantages of GraphicsMagick, but one for all:

• GM is used to process billions of files at the world's largest photo sites (e.g. Flickr and Etsy).

Note that there are at least two bug reports for ssh-add -d/-D not removing keys:

• "Debian Bug report #472477: ssh-add -D does not remove SSH key from gnome-keyring-daemon memory"
• "Ubuntu: ssh-add -D deleting all identities does not work. Also, why are all identities auto-added?"

The exact issue is:

ssh-add -d/-D deletes only manually added keys from gnome-keyring.
There is no way to delete automatically added keys.
This is the original bug, and it's still definitely present.

So, for example, if you have two different automatically-loaded ssh identities associated with two different GitHub accounts -- say for work and for home -- there's no way to switch between them. GitHubtakes the first one which matches, so you always appear as your 'home' user to GitHub, with no way to upload things to work projects.

Allowing ssh-add -d to apply to automatically-loaded keys (and ssh-add -t X to change the lifetime of automatically-loaded keys), would restore the behavior most users expect.

More precisely, about the issue:

The culprit is gpg-keyring-daemon:

• It subverts the normal operation of ssh-agent, mostly just so that it can pop up a pretty box into which you can type the passphrase for an encrypted ssh key.

• And it paws through your .ssh directory, and automatically adds any keys it finds to your agent.
• And it won't let you delete those keys.

How do we hate this? Let's not count the ways -- life's too short.

The failure is compounded because newer ssh clients automatically try all the keys in your ssh-agent when connecting to a host.
If there are too many, the server will reject the connection.
And since gnome-keyring-daemon has decided for itself how many keys you want your ssh-agent to have, and has autoloaded them, AND WON'T LET YOU DELETE THEM, you're toast.

This bug is still confirmed in Ubuntu 14.04.4, as recently as two days ago (August 21st, 2014)

A possible workaround:

• Do ssh-add -D to delete all your manually added keys. This also locks the automatically added keys, but is not much use since gnome-keyring will ask you to unlock them anyways when you try doing a git push.

• Navigate to your ~/.ssh folder and move all your key files except the one you want to identify with into a separate folder called backup. If necessary you can also open seahorse and delete the keys from there.
• Now you should be able to do git push without a problem.

Another workaround:

What you really want to do is to turn off gpg-keyring-daemon altogether.
Go to System --> Preferences --> Startup Applications, and unselect the "SSH Key Agent (Gnome Keyring SSH Agent)" box -- you'll need to scroll down to find it.

You'll still get an ssh-agent, only now it will behave sanely: no keys autoloaded, you run ssh-add to add them, and if you want to delete keys, you can. Imagine that.

This comments actually suggests:

The solution is to keep gnome-keyring-manager from ever starting up, which was strangely difficult by finally achieved by removing the program file's execute permission.

Ryan Lue adds another interesting corner case in the comments:

In case this helps anyone: I even tried deleting the id_rsa and id_rsa.pub files altogether, and the key was still showing up.

Turns out gpg-agent was caching them in a ~/.gnupg/sshcontrol file; I had to manually delete them from there.

That is the case when the keygrip has been added as in here.

Found a way to do this, simply add a querystring to load your components, like so:

@Component({
  selector: 'some-component',
  templateUrl: `./app/component/stuff/component.html?v=${new Date().getTime()}`,
  styleUrls: [`./app/component/stuff/component.css?v=${new Date().getTime()}`]
})

This should force the client to load the server's copy of the template instead of the browser's. If you would like it to refresh only after a certain period of time you could use this ISOString instead:

new Date().toISOString() //2016-09-24T00:43:21.584Z

And substring some characters so that it will only change after an hour for example:

new Date().toISOString().substr(0,13) //2016-09-24T00

Hope this helps

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

Your SVG must be inline in your document in order to be styled with CSS. This can be done by writing the SVG markup directly into your HTML code, or by using SVG injection, which replaces the img element with the content from and SVG file with Javascript.

There is an open source library called SVGInject that does this for you. All you have to do is to add the attribute onload="SVGInject(this)" to you <img> tag.

A simple example using SVGInject looks like this:

<html>
  <head>
    <script src="svg-inject.min.js"></script>
  </head>
  <body>
    <img src="image.svg" onload="SVGInject(this)" />
  </body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the SVG file provided in the src attribute.

If the cart has to be stored as an object and not array (Although I would recommend storing as an []) you can always change the structure to use the ID as the key:

var element = { quantity: quantity };
cart[id] = element;

This allows you to add multiple items to the cart like so:

cart["1"] = { quantity: 5};
cart["2"] = { quantity: 10};

// Cart is now:
// { "1": { quantity: 5 }, "2": { quantity: 10 } }

I just added H:i:s to Rocket's answer to get the time along with the date.

echo date('m/d/Y H:i:s', 1299446702);

Output: 03/06/2011 16:25:02

All development is done using your choice of C#, Boo, or a dialect of JavaScript.

• C# needs no explanation :)
• Boo is a CLI language with very similar syntax to Python; it is, however, statically typed and has a few other differences. It's not "really" Python; it just looks similar.
• The version of JavaScript used by Unity is also a CLI language, and is compiled. Newcomers often assume JS isn't as good as the other three, but it's compiled and just as fast and functional.

Most of the example code in the documentation is in JavaScript; if you poke around the official forums and wiki you'll see a pretty even mix of C# and Javascript. Very few people seem to use Boo, but it's just as good; pick the language you already know or are the happiest learning.

Unity takes your C#/JS/Boo code and compiles it to run on iOS, Android, PC, Mac, XBox, PS3, Wii, or web plugin. Depending on the platform that might end up being Objective C or something else, but that's completely transparent to you. There's really no benefit to knowing Objective C; you can't program in it.

Update 2019/31/01

Starting from Unity 2017.2 "UnityScript" (Unity's version of JavaScript, but not identical to) took its first step towards complete deprecation by removing the option to add a "JavaScript" file from the UI. Though JS files could still be used, support for it will completely be dropped in later versions.

This also means that Boo will become unusable as its compiler is actually built as a layer on top of UnityScript and will thus be removed as well.

This means that in the future only C# will have native support.

unity has released a full article on the deprecation of UnityScript and Boo back in August 2017.

I would try

Sheets("Sheet1").Activate
Set Ticker = Range(Cells(2, 1), Cells(65, 1))
Ticker.Copy

Worksheets("Sheet2").Range("A1").Offset(0,0).Cells.Select
Worksheets("Sheet2").paste

Arrays.toString(thrown.getStackTrace())

Is the easiest way to convert the result into String I am using this in my program to print the stack trace

LOGGER.log(Level.SEVERE, "Query Builder Issue Stack Trace : {0} ,Message : {1} objid {2}", new Object[]{Arrays.toString(e.getStackTrace()), e.getMessage(),objId});

This is more of a maths problem than a java problem basically.

The result you receive is correct. This because 225 seconds is 3 minutes (when doing an integral division). What you want is the this:

• divide by 1000 to get the number of seconds -> rest is milliseconds
• divide that by 60 to get number of minutes -> rest are seconds
• divide that by 60 to get number of hours -> rest are minutes

or in java:

int millis = diff % 1000;
diff/=1000;
int seconds = diff % 60;
diff/=60;
int minutes = diff % 60;
diff/=60;
hours = diff;

You can put an image instead, and do it like this:

HTML:

<img src="/images/uploadButton.png" id="upfile1" style="cursor:pointer" />
<input type="file" id="file1"  name="file1" style="display:none" />

JQuery:

$("#upfile1").click(function () {
    $("#file1").trigger('click');
});

CAVEAT: In IE9 and IE10 if you trigger the onclick in a file input via javascript the form gets flagged as 'dangerous' and cannot be submmited with javascript, no sure if it can be submitted traditionaly.

Try adding animation-fill-mode: forwards;. For example like this:

-webkit-animation: bubble 1.0s forwards; /* for less modern browsers */
        animation: bubble 1.0s forwards;

Look how I format my date $jour in the parameters. It depends if you use a expr()->like or a expr()->lte

$qb
        ->select('e')
        ->from('LdbPlanningBundle:EventEntity', 'e')
        ->where(
            $qb->expr()->andX(
                $qb->expr()->orX(
                    $qb->expr()->like('e.start', ':jour1'),
                    $qb->expr()->like('e.end', ':jour1'),
                    $qb->expr()->andX(
                        $qb->expr()->lte('e.start', ':jour2'),
                        $qb->expr()->gte('e.end', ':jour2')
                    )
                ),
                $qb->expr()->eq('e.user', ':user')
            )
        )
        ->andWhere('e.user = :user ')
        ->setParameter('user', $user)
        ->setParameter('jour1', '%'.$jour->format('Y-m-d').'%')
        ->setParameter('jour2', $jour->format('Y-m-d'))
        ->getQuery()
        ->getArrayResult()
    ;

Try this

User.where("id > ?", 200) 

use long startTime=System.currentTimeMillis() for start time, at the top of the loop

put long endTime= System.currentTimeMillis(); outside the end of the loop. You'll have to subtract the values to get the runtime in milliseconds.

If you want time in nanoseconds, check out System.nanoTime()

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.

When you need to do it in a string (eg: in your resources) you need to use xml:space="preserve" and the ampersand character codes:

<System:String x:Key="TwoLiner" xml:space="preserve">First line&#10;Second line</System:String>

Or literal newlines in the text:

<System:String x:Key="TwoLiner" xml:space="preserve">First line 
Second line</System:String>

Warning: if you write code like the second example, you have inserted either a newline, or a carriage return and newline, depending on the line endings your operating system and/or text editor use. For instance, if you write that and commit it to git from a linux systems, everything may seem fine -- but if someone clones it to Windows, git will convert your line endings to \r\n and depending on what your string is for ... you might break the world.

Just be aware of that when you're preserving whitespace. If you write something like this:

<System:String x:Key="TwoLiner" xml:space="preserve">
First line 
Second line 
</System:String>

You've actually added four line breaks, possibly four carriage-returns, and potentially trailing white space that's invisible...

An inner class, by definition, cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?"

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.

I encountered

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from projects)

The cause was that I had not started the MySQL server.

It may help to check that the MySQL is running as the first step in troubleshooting the error.

@media (max-width: 767px) {
    footer .text-right, 
    footer .text-left {
        text-align: center;
    } 
}

I updated @loddn's answer, making two changes

• max-width of xs screens in bootstrap is 767px (768px is the start of sm screens)
• (this one is a matter of preference) I used footer instead of col-* so that if the column widths change, the CSS doesn't need to be updated.

I use

decimal Debitvalue = 1156.547m;
decimal DEBITAMT = Convert.ToDecimal(string.Format("{0:F2}", Debitvalue));

Another way is :

const result = [] as  any;

Well you just remove the desired item from the list using the remove() method of your ArrayAdapter.

A possible way to do that would be:

Object toRemove = arrayAdapter.getItem([POSITION]);
arrayAdapter.remove(toRemove);

Another way would be to modify the ArrayList and call notifyDataSetChanged() on the ArrayAdapter.

arrayList.remove([INDEX]);
arrayAdapter.notifyDataSetChanged();

Map.of literals

As of Java 9, there is yet another way to instantiate a Map. You can create an unmodifiable map from zero, one, or several pairs of objects in a single-line of code. This is quite convenient in many situations.

For an empty Map that cannot be modified, call Map.of(). Why would you want an empty set that cannot be changed? One common case is to avoid returning a NULL where you have no valid content.

For a single key-value pair, call Map.of( myKey , myValue ). For example, Map.of( "favorite_color" , "purple" ).

For multiple key-value pairs, use a series of key-value pairs. ``Map.of( "favorite_foreground_color" , "purple" , "favorite_background_color" , "cream" )`.

If those pairs are difficult to read, you may want to use Map.of and pass Map.Entry objects.

Note that we get back an object of the Map interface. We do not know the underlying concrete class used to make our object. Indeed, the Java team is free to used different concrete classes for different data, or to vary the class in future releases of Java.

The rules discussed in other Answers still apply here, with regard to type-safety. You declare your intended types, and your passed objects must comply. If you want values of various types, use Object.

Map< String , Color > preferences = Map.of( "favorite_color" , Color.BLUE ) ;

Here is one simple PHP Script which gets exchange rate between GBP and USD

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

Google currency rates are not accurate google itself says ==> Google cannot guarantee the accuracy of the exchange rates used by the calculator. You should confirm current rates before making any transactions that could be affected by changes in the exchange rates. Foreign currency rates provided by Citibank N.A. are displayed under licence. Rates are for information purposes only and are subject to change without notice. Rates for actual transactions may vary and Citibank is not offering to enter into any transaction at any rate displayed.

Typescript 3.4 introduces the new 'const' assertion

You can now prevent literal types (eg. 'orange' or 'red') being 'widened' to type string with a so-called const assertion.

You will be able to do:

let fruit = 'orange' as const;  // or...
let fruit = <const> 'orange';

And then it won't turn itself into a string anymore - which is the root of the problem in the question.

If you want to modify this I'd go with either of the following:

List<string[]> results;

-- or --

List<List<string>> results;

depending on your needs...

If you are creating the URL from the server side of an ASP.NET application, and deploying your website to a virtual directory (e.g. app2) in your website i.e. http://www.yourwebsite.com/app2/

then just insert

<base href="~/" />

just after the title tag.

so whenever you use root relative e.g.

<a href="/Accounts/Login"/> 

would resolve to "http://www.yourwebsite.com/app2/Accounts/Login"

This way you can always point to your files relatively-absolutely ;)

To me this is the most flexible solution.

You can use encoding like ASCII to get a character per byte by using the System.Text.Encoding class.

or try this

  System.Text.ASCIIEncoding.Unicode.GetByteCount(string);
  System.Text.ASCIIEncoding.ASCII.GetByteCount(string);

If you use UPPER(text), the like '%lah%' will always return zero results. Use '%LAH%'.

Use UITextView instead of UILabel and it has a property to convert your text to hyperlink

Swift code:

yourTextView.editable = false
yourTextView.dataDetectorTypes = UIDataDetectorTypes.All
//or
yourTextView.dataDetectorTypes = UIDataDetectorTypes.PhoneNumber
//or
yourTextView.dataDetectorTypes = UIDataDetectorTypes.Link

You can/should set your parameter to value to DBNull.Value;

if (variable == "")
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}

Or you can leave your server side set to null and not pass the param at all.

Below, is the most clean, comprehensible way of merging multiple dataframe if complex queries aren't involved.

Just simply merge with DATE as the index and merge using OUTER method (to get all the data).

import pandas as pd
from functools import reduce

df1 = pd.read_table('file1.csv', sep=',')
df2 = pd.read_table('file2.csv', sep=',')
df3 = pd.read_table('file3.csv', sep=',')

Now, basically load all the files you have as data frame into a list. And, then merge the files using merge or reduce function.

# compile the list of dataframes you want to merge
data_frames = [df1, df2, df3]

Note: you can add as many data-frames inside the above list. This is the good part about this method. No complex queries involved.

To keep the values that belong to the same date you need to merge it on the DATE

df_merged = reduce(lambda  left,right: pd.merge(left,right,on=['DATE'],
                                            how='outer'), data_frames)

# if you want to fill the values that don't exist in the lines of merged dataframe simply fill with required strings as

df_merged = reduce(lambda  left,right: pd.merge(left,right,on=['DATE'],
                                            how='outer'), data_frames).fillna('void')

• Now, the output will the values from the same date on the same lines.
• You can fill the non existing data from different frames for different columns using fillna().

Then write the merged data to the csv file if desired.

pd.DataFrame.to_csv(df_merged, 'merged.txt', sep=',', na_rep='.', index=False)

This should give you

DATE VALUE1 VALUE2 VALUE3 ....

function WordCount(str) {
    var totalSoFar = 0;
    for (var i = 1; i < str.length; i++) {
        if (str[i] === " ") {
            totalSoFar ++;
        }
    }
    return totalSoFar; 
}
console.log(WordCount("hi my name is raj));

The following is Yet Another Way (tm) - still involves a little calculation but provides an example of using EXTRACT to pull the individual fields out of an INTERVAL:

DECLARE 
  SUBTYPE BIG_INTERVAL IS INTERVAL DAY(9) TO SECOND;

  i        BIG_INTERVAL;
  nSeconds NUMBER := 86400000;

  FUNCTION INTERVAL_TO_HMS_STRING(inv IN BIG_INTERVAL)
    RETURN VARCHAR2
  IS
    nHours    NUMBER;
    nMinutes  NUMBER;
    nSeconds  NUMBER;
    strHour_format  VARCHAR2(10) := '09';
    workInv   INTERVAL DAY(9) TO SECOND(9);
  BEGIN
    nHours := EXTRACT(HOUR FROM inv) + (EXTRACT(DAY FROM inv) * 24);
    strHour_format := TRIM(RPAD(' ', LENGTH(TRIM(TO_CHAR(ABS(nHours)))), '0') || '9');

    nMinutes := ABS(EXTRACT(MINUTE FROM inv));
    nSeconds := ABS(EXTRACT(SECOND FROM inv));

    RETURN TRIM(TO_CHAR(nHours, strHour_format)) || ':' ||
           TRIM(TO_CHAR(nMInutes, '09')) || ':' ||
           TRIM(TO_CHAR(nSeconds, '09'));
  END INTERVAL_TO_HMS_STRING;

BEGIN
  i := NUMTODSINTERVAL(nSeconds, 'SECOND');

  DBMS_OUTPUT.PUT_LINE('i (fields) = ' || INTERVAL_TO_HMS_STRING(i));
END;

The code which extracts the fields, etc, still has to contain a calculation to convert the DAY field to equivalent hours, and is not the prettiest, but wrapped up neatly in a procedure it's not too bad to use.

Share and enjoy.

This is a question with a simple answer and a long-winded answer.

The simple answer is the heap. Classes and all of the data applying to classes (not instance data) is stored in the Permanent Generation section of the heap.

The long answer is already on stack overflow:

There is a thorough description of memory and garbage collection in the JVM as well as an answer that talks more concisely about it.

I don't remember the specific source, but I am using:

    }

You may want to tinker with the specific values to fit your needs.

My issue was much simpler. I had created a shortcut to launch the eclipse executable by dragging it from the folder to the screen. Clicking on the created shortcut icon gave the above error.

Issue: the executable was getting launched from the desktop location instead of the eclipse directory where it had been unzipped.

Solution: Create a new shortcut by right-clicking in the desktop area and providing the target executable from the browse window. This creates the shortcut properly and launches the executable from the right home directory.

In Swift 3, you can use isNavigationBarHidden Property also to show or hide navigation bar

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    // Hide the navigation bar for current view controller
    self.navigationController?.isNavigationBarHidden = true;

__FILE__ is the filename with extension of the file containing the code being executed.

In foo.rb, __FILE__ would be "foo.rb".

If foo.rb were in the dir /home/josh then File.dirname(__FILE__) would return /home/josh.

It's just like you did. And I'll give you a small tip for these kind of silly things: just use the browser url box to try js syntax. for example, write this: javascript:alert("test"+5) and you have your answer. The problem in your code is probably that this element does not exist in your document... maybe it's inside a form or something. You can test this too by writing in the url: javascript:alert(document.horseThumb_5) to check where your mistake is.

If you are using pwsh (powershell core), you can try

(docker ps --format='{{json .}}' |  ConvertFrom-Json).Mounts

also you can see both container name and Mounts as below

docker ps --format='{{json .}}' |  ConvertFrom-Json | select Names,Mounts

As the output is converted as json ,you can get any properties it has.

This is an old question, but the current answers are incorrect :)

Use yum whatprovides, with the absolute path to the file you want (which may be wildcarded). For example:

yum whatprovides '*bin/grep'

Returns

grep-2.5.1-55.el5.x86_64 : The GNU versions of grep pattern matching utilities.
Repo        : base
Matched from:
Filename    : /bin/grep

You may prefer the output and speed of the repoquery tool, available in the yum-utils package.

sudo yum install yum-utils
repoquery --whatprovides '*bin/grep'
grep-0:2.5.1-55.el5.x86_64
grep-0:2.5.1-55.el5.x86_64

repoquery can do other queries such as listing package contents, dependencies, reverse-dependencies, etc.

You can use sp_lock (and sp_lock2), but in SQL Server 2005 onwards this is being deprecated in favour of querying sys.dm_tran_locks:

select  
    object_name(p.object_id) as TableName, 
    resource_type, resource_description
from
    sys.dm_tran_locks l
    join sys.partitions p on l.resource_associated_entity_id = p.hobt_id

To remove bullet from UL you can simply use list-style: none; or list-style-type: none; If still not works then i guess there is an issue of priority CSS. May be globally UL already defined. So best way add a class/ID to that particular UL and add your CSS there. Hope it will works.

I've created this query:

SELECT 
    db.name AS                                   [Database Name], 
    mf.name AS                                   [Logical Name], 
    mf.type_desc AS                              [File Type], 
    mf.physical_name AS                          [Path], 
    CAST(
        (mf.Size * 8
        ) / 1024.0 AS DECIMAL(18, 1)) AS         [Initial Size (MB)], 
    'By '+IIF(
            mf.is_percent_growth = 1, CAST(mf.growth AS VARCHAR(10))+'%', CONVERT(VARCHAR(30), CAST(
        (mf.growth * 8
        ) / 1024.0 AS DECIMAL(18, 1)))+' MB') AS [Autogrowth], 
    IIF(mf.max_size = 0, 'No growth is allowed', IIF(mf.max_size = -1, 'Unlimited', CAST(
        (
                CAST(mf.max_size AS BIGINT) * 8
        ) / 1024 AS VARCHAR(30))+' MB')) AS      [MaximumSize]
FROM 
     sys.master_files AS mf
     INNER JOIN sys.databases AS db ON
            db.database_id = mf.database_id

Use the getTime method to get the time in total milliseconds since 1970-01-01, and subtract those:

var time = new Date().getTime() - new Date("2013-02-20T12:01:04.753Z").getTime();

str = "[12,23,987,43"

str[0] = ""

In version 5.6 at least, the Management tab in MySQL Workbench shows that it's in a hidden folder called ProgramData in the C:\ drive. My default data directory is

C:\ProgramData\MySQL\MySQL Server 5.6\data

. Each database has a folder and each table has a file here.

GSON is a good option to convert java object to json object and vise versa.
It is a tool provided by google.

for converting json to java object use: fromJson(jsonObject,javaclassname.class)
for converting java object to json object use: toJson(javaObject)
and rest will be done automatically

Try running this, where x is any number

int_sign = bool(x > 0) - bool(x < 0)

The coercion to bool() handles the possibility that the comparison operator doesn't return a boolean.

If you want an alternative to pickle or json, you can use klepto.

>>> init = {'y': 2, 'x': 1, 'z': 3}
>>> import klepto
>>> cache = klepto.archives.file_archive('memo', init, serialized=False)
>>> cache        
{'y': 2, 'x': 1, 'z': 3}
>>>
>>> # dump dictionary to the file 'memo.py'
>>> cache.dump() 
>>> 
>>> # import from 'memo.py'
>>> from memo import memo
>>> print memo
{'y': 2, 'x': 1, 'z': 3}

With klepto, if you had used serialized=True, the dictionary would have been written to memo.pkl as a pickled dictionary instead of with clear text.

You can get klepto here: https://github.com/uqfoundation/klepto

dill is probably a better choice for pickling then pickle itself, as dill can serialize almost anything in python. klepto also can use dill.

You can get dill here: https://github.com/uqfoundation/dill

The additional mumbo-jumbo on the first few lines are because klepto can be configured to store dictionaries to a file, to a directory context, or to a SQL database. The API is the same for whatever you choose as the backend archive. It gives you an "archivable" dictionary with which you can use load and dump to interact with the archive.

This could work:

import sys

def str_to_class(classname):
    return getattr(sys.modules[__name__], classname)

    public static string FormatXml(string xml)
    {
        try
        {
            var doc = XDocument.Parse(xml);
            return doc.ToString();
        }
        catch (Exception)
        {
            return xml;
        }
    }

Use the keyword size instead of fontsize.

Here is a list of commercial vendors that provide off-the-shelf packages for facial recognition which run on Windows:

1. Cybula - Information on their Facial Recognition SDK. This is a company founded by a University Professor and as such their website looks unprofessional. There's no pricing information or demo that you can download. You'll need to contact them for pricing information.

2. NeuroTechnology - Information on their Facial Recognition SDK. This company has both up-front pricing information as well as an actual 30 day trial of their SDK.

3. Pittsburgh Pattern Recognition - (Acquired by Google) Information on their Facial Tracking and Recognition SDK. The demos that they provide help you evaluate their technology but not their SDSK. You'll need to contact them for pricing information.

4. Sensible Vision - Information on their SDK. Their site allows you to easily get a price quote and you can also order an evaluation kit that will help you evaluate their technology.

The field must be declared public for proper visibility from the ASPX markup. In any case, you could declare a property:

private string clients;
public string Clients { get { return clients; } }

UPDATE: It can also be declared as protected, as stated in the comments below.

Then, to call it on the ASPX side:

<%=Clients%>

Note that this won't work if you place it on a server tag attribute. For example:

<asp:Label runat="server" Text="<%=Clients%>" />

This isn't valid. This is:

<div><%=Clients%></div>

While using string, the best possible way to print your message is:

#include <iostream>
#include <string>
using namespace std;

int main(){
  string newInput;
  getline(cin, newInput);
  cout<<newInput;
  return 0;
}

this can simply do the work instead of doing the method you adopted.

text-shadow: -1px 0 black, 0 1px black, 1px 0 black, 0 -1px black;

check this.. Brief:Pick each element of array and compare it with all elements of the array, weather it is equal to the picked on or not.

  int popularity1 = 0;
  int popularity2 = 0;
  int popularity_item, array_item; //Array contains integer value. Make it String if array contains string value.
  for(int i =0;i<array.length;i++){
      array_item = array[i];
      for(int j =0;j<array.length;j++){
          if(array_item == array[j])
             popularity1 ++;
          {
      if(popularity1 >= popularity2){
          popularity_item = array_item;
          popularity2 = popularity1;
      }
      popularity1 = 0;
  }
  //"popularity_item" contains the most repeted item in an array.

If you worry about getting the IP address but do not need or want to use any Laravel functionality, you can use just php:

PHP < 5.3.0
$localIP = getHostByName(php_uname('n'));

PHP >= 5.3.0
$localIP = getHostByName(getHostName());

as answered in this thread: PHP how to get local IP of system

It seems this may have recently been added. Clicking command + control + z on the simulator will pop up a debug menu. From that menu, click Inspect. Inspect will present tabs. Click the network tab and that will show all network requests being made.

Casting will ignore anything after the decimal point, so 8.6 becomes 8.

Convert.ToInt32(8.6) is the safe way to ensure your double gets rounded to the nearest integer, in this case 9.

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer. There are three different ways where Pointer acts as dangling pointer.

1. De-allocation of memory
2. Function Call
3. Variable goes out of scope

Modified Alec McGail's answer to support JSON with lists inside

    def flattenjson(self, mp, delim="|"):
            ret = []
            if isinstance(mp, dict):
                    for k in mp.keys():
                            csvs = self.flattenjson(mp[k], delim)
                            for csv in csvs:
                                    ret.append(k + delim + csv)
            elif isinstance(mp, list):
                    for k in mp:
                            csvs = self.flattenjson(k, delim)
                            for csv in csvs:
                                    ret.append(csv)
            else:
                    ret.append(mp)

            return ret

Thanks!

I found a workaround.

1. Export with a white background (or other color that will work with transparent graphics). This will be out "whitescreen" layer.
2. Export with "bluescreen" background, or some terrible other color that will make it easy to select out the background from foreground.
3. Open the bluescreen version as a layer on top of the white screen.
4. Use the bluescreen layer to select out only the parts you want to use.
5. Create a mask for the whitescreen layer with the selection made from the bluescreen layer.

This will get good results for edges and aliasing, whilst retaining a good color for the see-

This is much easier in Swift 3 and later using reduce:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let token = deviceToken.reduce("") { $0 + String(format: "%02x", $1) }

    DispatchQueue.global(qos: .background).async { 
        let url = URL(string: "https://example.com/myApp/apns.php")!

        var request = URLRequest(url: url)
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.httpMethod = "POST"
        request.httpBody = try! JSONSerialization.data(withJSONObject: [
            "token" : token, 
            "ios" : UIDevice.current.systemVersion,
            "languages" : Locale.preferredLanguages.joined(separator: ", ")
            ])

        URLSession.shared.dataTask(with: request).resume()
    }
}

Just added support for select element to Ryan Montgomery "fix"

This works fine for me using MySQL 5.1.35:

DELIMITER $$

DROP PROCEDURE IF EXISTS `example`.`test` $$
CREATE PROCEDURE `example`.`test` ()
BEGIN

  DECLARE FOO varchar(7);
  DECLARE oldFOO varchar(7);
  SET FOO = '138';
  SET oldFOO = CONCAT('0', FOO);

  update mypermits
     set person = FOO
   where person = oldFOO;

END $$

DELIMITER ;

Table:

DROP TABLE IF EXISTS `example`.`mypermits`;
CREATE TABLE  `example`.`mypermits` (
  `person` varchar(7) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO mypermits VALUES ('0138');

CALL test()

As explained already Google Compute Engine (GCE) is the Infrastructure as a service (IaaS) while Google App Engine (GAE) is Platform as a Service (PaaS). You can check the following diagram to understand the difference in a better way (Taken from and better explained here) -

Google Compute Engine
GCE is an important service provided from Google Cloud Platform (GCP) since most of the GCP services use GCE instances (VMs) beneath the management layer (not sure which one don't). This includes App Engine, Cloud Functions, Kubernetes Engine (Earlier Container Engine), Cloud SQL, etc. GCE instances are the most customisable unit there and thus should only be used when your application can't run on any other GCP services. Most of the time people use GCE to transfer their On-Prem applications to GCP, since it requires minimal changes. Later, they can choose to use other GCP services for separate component of their apps.

Google App Engine
GAE is the first service offered by GCP (Long before Google came to the cloud business). It autoscales from 0 to unlimited instances (It uses GCE underneath). It comes with 2 flavors Standard Environment and Flexible Environment.

Standard Environment is really fast, scales down to 0 instance when no-one is using your app, scales up and down in seconds and have dedicated Google services and libraries for caching, authentication etc. The caveat with Standard environment is that it is very restrictive since it runs in a sandbox. You have to use managed runtimes for specific programming languages only. The recent additions are Node.js (8.x) and Python 3.x. The older runtimes are available for Go, PHP, Python 2.7, Java etc.

Flexible Environment is more open as it allows you to use custom runtimes as it uses docker containers. Thus if your runtime is not available in the provided runtimes, you can always create your own dockerfile for the execution environment. The caveat with it is, it requires having at least 1 instance running, even if no-one is using your app, plus the scaling up and down requires few minutes.

Don't confuse GAE flexible with Kubernetes Engine, as the later one uses actual Kubernetes and provides much more customisation and features. GAE Flex is useful when you want stateless containers and your application rely on HTTP or HTTPS protocols only. For other protocols Kubernetes Engine (GKE) or GCE is your only choice. Check my other answer for better explanation.

Just sharing my experience on this. I was having this same issue. My query was like:

select table1.column2 from table1

However, table1 did not have column2 column.

You shouldn't be passing anything in to getCountry(). Remove Locale.getDefault():

String locale = context.getResources().getConfiguration().locale.getCountry();

I've also used Meld. It's written in python. There is an official installer for Windows that works well.

Install it and then set it as your default mergetool.

$ git config --global merge.tool "meld"
$ git config --global mergetool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"

If using a GUI GIT client, try the following (instructions for SourceTree, adjust accordingly)

• In SourceTree, go to Tools/Options/Diff
• In External Diff Tool, choose Custom
• Enter C:\Program Files (x86)\Meld\meld.exe in Diff Command and $LOCAL $REMOTE in Arguments
• In Merge Tool, choose Custom
• Enter C:\Program Files (x86)\Meld\meld.exe in Diff Command and $LOCAL $MERGED $REMOTE in Arguments

You need a spring-security-config.jar on your classpath.

The exception means that the security: xml namescape cannot be handled by spring "parsers". They are implementations of the NamespaceHandler interface, so you need a handler that knows how to process <security: tags. That's the SecurityNamespaceHandler located in spring-security-config

That's actually pretty easy, here's a possible approach:

<table>
    <tr>
        <th>
            <a href="?orderBy=type">Type:</a>
        </th>
        <th>
            <a href="?orderBy=description">Description:</a>
        </th>
        <th>
            <a href="?orderBy=recorded_date">Recorded Date:</a>
        </th>
        <th>
            <a href="?orderBy=added_date">Added Date:</a>
        </th>
    </tr>
</table>
<?php
$orderBy = array('type', 'description', 'recorded_date', 'added_date');

$order = 'type';
if (isset($_GET['orderBy']) && in_array($_GET['orderBy'], $orderBy)) {
    $order = $_GET['orderBy'];
}

$query = 'SELECT * FROM aTable ORDER BY '.$order;

// retrieve and show the data :)
?>

That'll do the trick! :)

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active> with <Active>true</Active>, like so:

cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -

If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.

What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
    <xsl:for-each select="XML">
        <xsl:for-each select="Active">
            <xsl:value-of select=" replace(current(), 'True','true')"/>
        </xsl:for-each>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Simplest solution:

To drop duplicates based on one column:

df = df.drop_duplicates('column_name', keep='last')

To drop duplicates based on multiple columns:

df = df.drop_duplicates(['col_name1','col_name2','col_name3'], keep='last')

Thank you for your responses. Turns out my problem was a database issue with duplicate entries, not with my logic. A quick table sync fixed that and the SUM feature worked as expected. This is all still useful knowledge for the SUM feature and is worth reading if you are having trouble using it.

You can also use an exit variable if you want your code to be a bit more readable:

DECLARE @Flag int = 0
DECLARE @Done bit = 0

WHILE @Done = 0 BEGIN
    SET @Flag = @Flag + 1
    PRINT @Flag
    IF @Flag >= 5 SET @Done = 1
END

This would probably be more relevant when you have a more complicated loop and are trying to keep track of the logic. As stated loops are expensive so try and use other methods if you can.

For python3 is:

sudo apt-get install -y python3-setuptools

You can cast your JToken to a JObject and then use the Properties() method to get a list of the object properties. From there, you can get the names rather easily.

Something like this:

string json =
@"{
    ""ADDRESS_MAP"":{

        ""ADDRESS_LOCATION"":{
            ""type"":""separator"",
            ""name"":""Address"",
            ""value"":"""",
            ""FieldID"":40
        },
        ""LOCATION"":{
            ""type"":""locations"",
            ""name"":""Location"",
            ""keyword"":{
                ""1"":""LOCATION1""
            },
            ""value"":{
                ""1"":""United States""
            },
            ""FieldID"":41
        },
        ""FLOOR_NUMBER"":{
            ""type"":""number"",
            ""name"":""Floor Number"",
            ""value"":""0"",
            ""FieldID"":55
        },
        ""self"":{
            ""id"":""2"",
            ""name"":""Address Map""
        }
    }
}";

JToken outer = JToken.Parse(json);
JObject inner = outer["ADDRESS_MAP"].Value<JObject>();

List<string> keys = inner.Properties().Select(p => p.Name).ToList();

foreach (string k in keys)
{
    Console.WriteLine(k);
}

Output:

ADDRESS_LOCATION
LOCATION
FLOOR_NUMBER
self

Woo-hoo! It works with some hack!

According to this comment you need to:

1. Manually edit Microsoft.CSharp.DesignTime.targets located in C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\VisualStudio\Managed (for VS Community edition, modify path for other editions), append ClassDesigner value to ProjectCapability (right pane):

2. Restart VS.

3. Manually create text file, say MyClasses.cd with following content: <?xml version="1.0" encoding="utf-8"?> <ClassDiagram MajorVersion="1" MinorVersion="1"> <Font Name="Segoe UI" Size="9" /> </ClassDiagram>

Bingo. Now you may open this file in VS. You will see error message "Object reference not set to an instance of object" once after VS starts, but diagram works.

An AngularJs directive for achieving this: To use it, add css class double-hscroll to your element. You will need jQuery and AngularJs for this.

import angular from 'angular';

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, $compile) {
  $scope.name = 'Dual wielded horizontal scroller';
});

app.directive('doubleHscroll', function($compile) {
  return {
restrict: 'C',
link: function(scope, elem, attr){

  var elemWidth = parseInt(elem[0].clientWidth);

  elem.wrap(`<div id='wrapscroll' style='width:${elemWidth}px;overflow:scroll'></div>`); 
  //note the top scroll contains an empty space as a 'trick' 
  $('#wrapscroll').before(`<div id='topscroll' style='height:20px; overflow:scroll;width:${elemWidth}px'><div style='min-width:${elemWidth}px'> </div></div>`);

  $(function(){
    $('#topscroll').scroll(function(){
      $("#wrapscroll").scrollLeft($("#topscroll").scrollLeft());
    });
    $('#wrapscroll').scroll(function() {
      $("#topscroll").scrollLeft($("#wrapscroll").scrollLeft());
    });

  });  

}

  };


});

I tried a couple of answers mentioned in this link, but couldn't figure out how to tell Jenkins about the user-selected branch. As mentioned in my previous comment in above thread, I had left the branch selector field empty.

But, during further investigations, I found another way to do the same thing - https://wiki.jenkins-ci.org/display/JENKINS/Git+Parameter+Plugin I found this method was a lot simpler, and had less things to configure!

Here's what I configured -

1. Installed the git parameter plugin
2. Checked the 'This build is parameterized' and added a 'Git parameter'

3. Added the following values:

4. Then in the git SCM section of the job I added the same value mentioned in the 'Name' section, as if it were an environment variable. (If you read the help for this git parameter plugin carefully, you will realize this)

After this I just ran the build, chose my branch(Jenkins checks out this branch before building) and it completed the build successfully, AND by choosing the branch that I had specified.

This is just a concept, but don't implement this without security checks and filtering! Otherwise script could hack your site!

Answer: if you control target site, you can setup the receiver script like:

1) set the iframe link with style parameter, like:

http://your_site.com/target.php?color=red

(the last phrase is a{color:red} encoded by urlencode function.

2) set the receiver page target.php like this:

<head>
..........
$col = FILTER_VAR(SANITIZE_STRING, $_GET['color']);
<style>.xyz{color: <?php echo (in_array( $col, ['red','yellow','green'])?  $col : "black") ;?> } </style>
..........

You should not use gets since it has no way to stop a buffer overflow. If the user types in more data than can fit in your buffer, you will most likely end up with corruption or worse.

In fact, ISO have actually taken the step of removing gets from the C standard (as of C11, though it was deprecated in C99) which, given how highly they rate backward compatibility, should be an indication of how bad that function was.

The correct thing to do is to use the fgets function with the stdin file handle since you can limit the characters read from the user.

But this also has its problems such as:

• extra characters entered by the user will be picked up the next time around.
• there's no quick notification that the user entered too much data.

To that end, almost every C coder at some point in their career will write a more useful wrapper around fgets as well. Here's mine:

#include <stdio.h>
#include <string.h>

#define OK       0
#define NO_INPUT 1
#define TOO_LONG 2
static int getLine (char *prmpt, char *buff, size_t sz) {
    int ch, extra;

    // Get line with buffer overrun protection.
    if (prmpt != NULL) {
        printf ("%s", prmpt);
        fflush (stdout);
    }
    if (fgets (buff, sz, stdin) == NULL)
        return NO_INPUT;

    // If it was too long, there'll be no newline. In that case, we flush
    // to end of line so that excess doesn't affect the next call.
    if (buff[strlen(buff)-1] != '\n') {
        extra = 0;
        while (((ch = getchar()) != '\n') && (ch != EOF))
            extra = 1;
        return (extra == 1) ? TOO_LONG : OK;
    }

    // Otherwise remove newline and give string back to caller.
    buff[strlen(buff)-1] = '\0';
    return OK;
}

with some test code:

// Test program for getLine().

int main (void) {
    int rc;
    char buff[10];

    rc = getLine ("Enter string> ", buff, sizeof(buff));
    if (rc == NO_INPUT) {
        printf ("No input\n");
        return 1;
    }

    if (rc == TOO_LONG) {
        printf ("Input too long\n");
        return 1;
    }

    printf ("OK [%s]\n", buff);

    return 0;
}

It provides the same protections as fgets in that it prevents buffer overflows but it also notifies the caller as to what happened and clears out the excess characters so that they do not affect your next input operation.

Feel free to use it as you wish, I hereby release it under the "do what you damn well want to" licence :-)

I got this error when unbeknownst to me, someone else was connected to the database in another SSMS session. After I signed them out the restore completed successfully.

How about one written in pure assembler :-) Don't forget to check out the benchmarks.

Correct syntax looks like this. See MSDN.

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p

  ON p.vTreasuryId COLLATE Latin1_General_CI_AS = f.RFC COLLATE Latin1_General_CI_AS 

The ENTER key merely activates the form's default submit button, which will be the first

<input type="submit" />

the browser finds within the form.

Therefore don't have a submit button, but something like

<input type="button" value="Submit" onclick="submitform()" /> 

EDIT: In response to discussion in comments:

This doesn't work if you have only one text field - but it may be that is the desired behaviour in that case.

The other issue is that this relies on Javascript to submit the form. This may be a problem from an accessibility point of view. This can be solved by writing the <input type='button'/> with javascript, and then put an <input type='submit' /> within a <noscript> tag. The drawback of this approach is that for javascript-disabled browsers you will then have form submissions on ENTER. It is up to the OP to decide what is the desired behaviour in this case.

I know of no way of doing this without invoking javascript at all.

Your title question and your example are completely different. I'll start by answering the title question:

$("a").removeAttr("href");

And as far as not requiring an href, the generally accepted way of doing this is:

<a href"#" onclick="doWork(); return false;">link</a>

The return false is necessary so that the href doesn't actually go anywhere.

Although this have an accepted answer I would like to add an observation:

In ES6 using let doesn't work:

/*this is NOT working*/_x000D_
let t = "skyBlue",_x000D_
    m = "gold",_x000D_
    b = "tomato";_x000D_
_x000D_
let color = window["b"];_x000D_
console.log(color);

However using var works

/*this IS working*/_x000D_
var t = "skyBlue",_x000D_
    m = "gold",_x000D_
    b = "tomato";_x000D_
_x000D_
let color = window["b"];_x000D_
console.log(color);

I hope this may be useful to some.

If you forward-declare Flight and Landing in Event.h, then you should be fixed.

Remember to #include "Flight.h" and #include "Landing.h" in your implementation file for Event.

The general rule of thumb is: if you derive from it, or compose from it, or use it by value, the compiler must know its full definition at the time of declaration. If you compose from a pointer-to-it, the compiler will know how big a pointer is. Similarly, if you pass a reference to it, the compiler will know how big the reference is, too.

You can use java.util.Scanner (API):

import java.util.Scanner;

//...

Scanner in = new Scanner(System.in);
int num = in.nextInt();

It can also tokenize input with regular expression, etc. The API has examples and there are many others in this site (e.g. How do I keep a scanner from throwing exceptions when the wrong type is entered?).

Make sure you import the right annotation, because I had the same problem as you.

Hello, Swift

Complementing what @Francescu answered.

Adding extra parameters:

func test(function:String -> String, param1:String, param2:String) -> String
{
    return function("test"+param1 + param2)
}

func funcStyle(s:String) -> String
{
    return "FUNC__" + s + "__FUNC"
}
let resultFunc = test(funcStyle, "parameter 1", "parameter 2")

let blockStyle:(String) -> String = {s in return "BLOCK__" + s + "__BLOCK"}
let resultBlock = test(blockStyle, "parameter 1", "parameter 2")

let resultAnon = test({(s:String) -> String in return "ANON_" + s + "__ANON" }, "parameter 1", "parameter 2")


println(resultFunc)
println(resultBlock)
println(resultAnon)

You can use peek to do that.

List<Fruit> newList = fruits.stream()
    .peek(f -> f.setName(f.getName() + "s"))
    .collect(Collectors.toList());

You can do it this way.

try:
    a = [i for i in [20] if False][0]
except IndexError:
    print("Do what ever you want here")

You can solve your problem this way but, using 'try/except block' is not the best practice for python.

Left, Right and Below tabs were removed from Bootstrap 3, but you can add custom CSS to achieve this..

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

You can use simple date format in Java using the code below

SimpleDateFormat simpledatafo = new SimpleDateFormat("dd/MM/yyyy");
Date newDate = new Date();
String expectedDate= simpledatafo.format(newDate);

I hope this will meet your requirement

import PyPDF4
import io

pdfFile = open(r'test.pdf', 'rb')
pdfReader = PyPDF4.PdfFileReader(pdfFile)
pageObj = pdfReader.getPage(1)
pagetext = pageObj.extractText()

for line in io.StringIO(pagetext):
    print(line)

Right click on the project in the Solution window of Visual Studio, select "Debugging" (on the left side), and enter the arguments into the field "Command Arguments":

The latest way to go is to use the unit 'ch' which stands for character.

You can simply write:

p { max-width: 75ch; }

The only trick is that whitespaces won't be counted as characters..

I was just wondering how the random number generator in C# works.

That's implementation-specific, but the wikipedia entry for pseudo-random number generators should give you some ideas.

I was also curious how I could make a program that generates random WHOLE INTEGER numbers from 1-100.

You can use Random.Next(int, int):

Random rng = new Random();
for (int i = 0; i < 10; i++)
{
    Console.WriteLine(rng.Next(1, 101));
}

Note that the upper bound is exclusive - which is why I've used 101 here.

You should also be aware of some of the "gotchas" associated with Random - in particular, you should not create a new instance every time you want to generate a random number, as otherwise if you generate lots of random numbers in a short space of time, you'll see a lot of repeats. See my article on this topic for more details.

The answer of JasonW is fine. But since apache httpd 2.4.6 there is a alternative: mod_remoteip

All what you must do is:

1. May be you must install the mod_remoteip package

2. Enable the module:

   LoadModule remoteip_module modules/mod_remoteip.so
   

3. Add the following to your apache httpd config. Note that you must add this line not into the configuration of the proxy server. You must add this to the configuration of the proxy target httpd server (the server behind the proxy):

   RemoteIPHeader X-Forwarded-For
   

See at http://httpd.apache.org/docs/trunk/mod/mod_remoteip.html for more informations and more options.

It's showing the backslash because you're also escaping the backslash.

Aside from double quotes, you must also escape backslashes if you want to include one in your JSON quoted string. However if you intend to use a backslash in an escape sequence, obviously you shouldn't escape it.

You can use .is().

if( $('#leftmenu').is(':empty') ) {

Or you could just test the length property to see if one was found:

if( $('#leftmenu:empty').length ) {

You can use $.trim() to remove whitespace (if that's what you want) and check for the length of the content.

if( !$.trim( $('#leftmenu').html() ).length ) {

If you are using the latest version of Android studio. then you don't need to install additional software for Git other than GIT itself - https://git-scm.com/downloads

Steps

1. Create an account on Github - https://github.com/join
2. Install Git
3. Open your working project in Android studio
4. GoTo - File -> Settings -> Version Controll -> GitHub
5. Enter Login and Password which you have created just on Git Account and click on test
6. Once all credentials are true - it shows Success message. o.w Invalid Cred.
7. Now click on VCS in android studio menu bar
8. Select Import into Version Control -> Share Project on GitHub
9. The popup dialog will occure contains all your files with check mark, do ok or commit all
10. At next time whenever you want to push your project just click on VCS - > Commit Changes -> Commmit and Push.

That's it. You can find your project on your github now

if(c is TFrom)
{
   // Do Stuff
}

or if you plan on using c as a TForm, use the following example:

var tForm = c as TForm;
if(tForm != null)
{
   // c is of type TForm
}

The second example only needs to check to see if c is of type TForm once. Whereis if you check if see if c is of type TForm then cast it, the CLR undergoes an extra check. Here is a reference.

Edit: Stolen from Jon Skeet

If you want to make sure c is of TForm and not any class inheriting from TForm, then use

if(c.GetType() == typeof(TForm))
{
   // Do stuff cause c is of type TForm and nothing else
}

Alternative answer to an older question refers to John Skeet's Library that has tools for letting you write primitive data types directly into a byte[] with an Index offset. Far better than BitConverter if you need performance.

Older thread discussing this issue here

John Skeet's Libraries are here

Just download the source and look at the MiscUtil.Conversion namespace. EndianBitConverter.cs handles everything for you.

As of Python 3.7, datetime.datetime.fromisoformat() can handle your format:

>>> import datetime
>>> datetime.datetime.fromisoformat('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=72000)))

In older Python versions you can't, not without a whole lot of painstaking manual timezone defining.

Python does not include a timezone database, because it would be outdated too quickly. Instead, Python relies on external libraries, which can have a far faster release cycle, to provide properly configured timezones for you.

As a side-effect, this means that timezone parsing also needs to be an external library. If dateutil is too heavy-weight for you, use iso8601 instead, it'll parse your specific format just fine:

>>> import iso8601
>>> iso8601.parse_date('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=<FixedOffset '-04:00'>)

iso8601 is a whopping 4KB small. Compare that tot python-dateutil's 148KB.

As of Python 3.2 Python can handle simple offset-based timezones, and %z will parse -hhmm and +hhmm timezone offsets in a timestamp. That means that for a ISO 8601 timestamp you'd have to remove the : in the timezone:

>>> from datetime import datetime
>>> iso_ts = '2012-11-01T04:16:13-04:00'
>>> datetime.strptime(''.join(iso_ts.rsplit(':', 1)), '%Y-%m-%dT%H:%M:%S%z')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(-1, 72000)))

The lack of proper ISO 8601 parsing is being tracked in Python issue 15873.

/^[\+\-]?\d*\.?\d+(?:[Ee][\+\-]?\d+)?$/

check if a key is pressed, if yes, then do stuff

Consider 'select()', if this (reportedly Posix) function is available on your os.

'select()' uses 3 sets of bits, which you create using functions provided (see man select, FD_SET, etc). You probably only need create the input bits (for now)

from man page:

'select()' "allow a program to monitor multiple file descriptors, waiting until one or more of the file descriptors become "ready" for some class of I/O operation (e.g., input possible). A file descriptor is considered ready if it is possible to perform a corresponding I/O operation (e.g., read(2) without blocking...)"

When select is invoked:

a) the function looks at each fd identified in the sets, and if that fd state indicates you can do something (perhaps read, perhaps write), select will return and let you go do that ... 'all you got to do' is scan the bits, find the set bit, and take action on the fd associated with that bit.

The 1st set (passed into select) contains active input fd's (typically devices). Probably 1 bit in this set is all you will need. And with only 1 fd (i.e. an input from keyboard), 1 bit, this is all quite simple. With this return from select, you can 'do-stuff' (perhaps, after you have fetched the char).

b) the function also has a timeout, with which you identify how much time to await a change of the fd state. If the fd state does not change, the timeout will cause 'select()' to return with a 0. (i.e. no keyboard input) Your code can do something at this time, too, perhaps an output.

fyi - fd's are typically 0,1,2... Remembe that C uses 0 as STDIN, 1 and STDOUT.

Simple test set up: I open a terminal (separate from my console), and type the tty command in that terminal to find its id. The response is typically something like "/dev/pts/0", or 3, or 17...

Then I get an fd to use in 'select()' by using open:

// flag options are: O_RDONLY, O_WRONLY, or O_RDWR
int inFD = open( "/dev/pts/5", O_RDONLY ); 

It is useful to cout this value.

Here is a snippet to consider (from man select):

  fd_set rfds;
  struct timeval tv;
  int retval;

  /* Watch stdin (fd 0) to see when it has input. */
  FD_ZERO(&rfds);
  FD_SET(0, &rfds);

  /* Wait up to five seconds. */
  tv.tv_sec = 5;
  tv.tv_usec = 0;

  retval = select(1, &rfds, NULL, NULL, &tv);
  /* Don't rely on the value of tv now! */

  if (retval == -1)
      perror("select()");
  else if (retval)
      printf("Data is available now.\n");  // i.e. doStuff()
      /* FD_ISSET(0, &rfds) will be true. */
  else
      printf("No data within five seconds.\n"); // i.e. key not pressed

This is and old question, but now on PHP 7.1 you can define constant visibility.

EXAMPLE

<?php
class Foo {
    // As of PHP 7.1.0
    public const BAR = 'bar';
    private const BAZ = 'baz';
}
echo Foo::BAR . PHP_EOL;
echo Foo::BAZ . PHP_EOL;
?>

Output of the above example in PHP 7.1:

bar

Fatal error: Uncaught Error: Cannot access private const Foo::BAZ in …

Note: As of PHP 7.1.0 visibility modifiers are allowed for class constants.

Try the following. It is the most reliable solution:

window.getComputedStyle(x).display == ""

For example,

var x = document.createElement("html")
var y = document.createElement("body")
var z = document.createElement("div")
x.appendChild(y);
y.appendChild(z);

z.style.display = "block";

console.log(z.closest("html") == null); // 'false'
console.log(z.style.display); // 'block'
console.log(window.getComputedStyle(z).display == ""); // 'true'

It is Widget.ProgressBar.Horizontal on my phone, if I set android:indeterminate="true"

Try something like this to convert JToken to JArray:

static public JArray convertToJArray(JToken obj)
{
    // if ((obj).Type == JTokenType.Null) --> You can check if it's null here

    if ((obj).Type == JTokenType.Array)
        return (JArray)(obj);
    else
        return new JArray(); // this will return an empty JArray
}

In my case, I tried xcode-select --install but it says that it's not available from the store. Then, inspired by Rimian, I checked my gcc : gcc -v and then I got a message saying I did not aggreed.

From that point I just followed the agreement process from gcc -v, after I agreed it works fine for me.

This is an excerpt from method of mine, which converts a DataTable (the dt variable) into an array and then writes the array into a Range on a worksheet (wsh var). You can also change the topRow variable to whatever row you want the array of strings to be placed at.

object[,] arr = new object[dt.Rows.Count, dt.Columns.Count];
for (int r = 0; r < dt.Rows.Count; r++)
{
    DataRow dr = dt.Rows[r];
    for (int c = 0; c < dt.Columns.Count; c++)
    {
        arr[r, c] = dr[c];
    }
}
Excel.Range c1 = (Excel.Range)wsh.Cells[topRow, 1];
Excel.Range c2 = (Excel.Range)wsh.Cells[topRow + dt.Rows.Count - 1, dt.Columns.Count];
Excel.Range range = wsh.get_Range(c1, c2);
range.Value = arr;

Of course you do not need to use an intermediate DataTable like I did, the code excerpt is just to demonstrate how an array can be written to worksheet in single call.

Try this code:

<input type="text" name="Phone Number" pattern="[7-9]{1}[0-9]{9}" 
       title="Phone number with 7-9 and remaing 9 digit with 0-9">

This code will inputs only in the following format:

9238726384 (starting with 9 or 8 or 7 and other 9 digit using any number)
8237373746
7383673874

Incorrect format:
2937389471(starting not with 9 or 8 or 7)
32796432796(more than 10 digit)
921543(less than 10 digit)

WebKit now (and Chrome 12 at least) supports gradients as border image:

Can't be done as it stands... The code

def myMethod(pParm1='1', pParm2='2'){
    println "${pParm1}${pParm2}"
}

Basically makes groovy create the following methods:

Object myMethod( pParm1, pParm2 ) {
    println "$pParm1$pParm2"
}

Object myMethod( pParm1 ) {
    this.myMethod( pParm1, '2' )
}

Object myMethod() {
    this.myMethod( '1', '2' )
}

One alternative would be to have an optional Map as the first param:

def myMethod( Map map = [:], String mandatory1, String mandatory2 ){
    println "${mandatory1} ${mandatory2} ${map.parm1 ?: '1'} ${map.parm2 ?: '2'}"
}

myMethod( 'a', 'b' )                // prints 'a b 1 2'
myMethod( 'a', 'b', parm1:'value' ) // prints 'a b value 2'
myMethod( 'a', 'b', parm2:'2nd')    // prints 'a b 1 2nd'

Obviously, documenting this so other people know what goes in the magical map and what the defaults are is left to the reader ;-)

Something I found later which helped, is the .ReadWriteTimeout property. This, in addition to the .Timeout property seemed to finally cut down on the time threads would spend trying to download from a problematic server. The default time for .ReadWriteTimeout is 5 minutes, which for my application was far too long.

So, it seems to me:

.Timeout = time spent trying to establish a connection (not including lookup time) .ReadWriteTimeout = time spent trying to read or write data after connection established

More info: HttpWebRequest.ReadWriteTimeout Property

Edit:

Per @KyleM's comment, the Timeout property is for the entire connection attempt, and reading up on it at MSDN shows:

Timeout is the number of milliseconds that a subsequent synchronous request made with the GetResponse method waits for a response, and the GetRequestStream method waits for a stream. The Timeout applies to the entire request and response, not individually to the GetRequestStream and GetResponse method calls. If the resource is not returned within the time-out period, the request throws a WebException with the Status property set to WebExceptionStatus.Timeout.

(Emphasis mine.)

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

I made a really silly mistake for this. When I was getting same error every time i could not figure out what was wrong. then it clicked me that once I have closed all the projects in my work space and that was the time since all the problems started. SO just check whether your "appcompat_v7" is not closed. If it is then open the project by double click and then clean and build your project again. In my case the errors were gone. Happy coding!

This worked for me:

JSONObject jsonObj = new JSONObject();
jsonObj.put("phonetype","N95");
jsonObj.put("cat","WP");

jsonObj to Hashmap as following using gson

HashMap<String, Object> hashmap = new Gson().fromJson(jsonObj.toString(), HashMap.class);

a = ['a1','b2','c3']
b = ['a1','b2','c3']
c = ['b2','a1','c3']

# if you care about order
a == b # True
a == c # False

# if you don't care about order AND duplicates
set(a) == set(b) # True
set(a) == set(c) # True

By casting a, b and c as a set, you remove duplicates and order doesn't count. Comparing sets is also much faster and more efficient than comparing lists.

Above example is not Co-related Sub-Query. It is Derived Table / Inline-View since i.e, a Sub-query within FROM Clause.

A Corelated Sub-query should refer its parent(main Query) Table in it. For example See find the Nth max salary by Co-related Sub-query:

SELECT Salary 
FROM Employee E1
WHERE N-1 = (SELECT COUNT(*)
             FROM Employee E2
             WHERE E1.salary <E2.Salary) 

Co-Related Vs Nested-SubQueries.

Technical difference between Normal Sub-query and Co-related sub-query are:

1. Looping: Co-related sub-query loop under main-query; whereas nested not; therefore co-related sub-query executes on each iteration of main query. Whereas in case of Nested-query; subquery executes first then outer query executes next. Hence, the maximum no. of executes are NXM for correlated subquery and N+M for subquery.

2. Dependency(Inner to Outer vs Outer to Inner): In the case of co-related subquery, inner query depends on outer query for processing whereas in normal sub-query, Outer query depends on inner query.

3.Performance: Using Co-related sub-query performance decreases, since, it performs NXM iterations instead of N+M iterations. ¨ Co-related Sub-query Execution.

a is a pointer. You need to use->, not .

Just like the docs say

DB::table('orders')->max('id');

You can solve the issue by

1. Ignore the warning and Install XAMPP directly under C:/ folder. It will solve your issue
2. You can deactivate the UAC which i don't recommend. It's makes your PC less secure.

string test = "<body><head>test header</head></body>";

XmlDocument xmltest = new XmlDocument();
xmltest.LoadXml(test);

XmlNodeList elemlist = xmltest.GetElementsByTagName("head");

string result = elemlist[0].InnerXml; 

//result -> "test header"

You should include <string.h> (or its C++ equivalent, <cstring>).

LatLng hello = new LatLng(X, Y);          // whereX & Y are coordinates

Bitmap icon = BitmapFactory.decodeResource(getApplicationContext().getResources(),
                R.drawable.university);   // where university is the icon name that is used as a marker.

mMap.addMarker(new MarkerOptions().icon(BitmapDescriptorFactory.fromBitmap(icon)).position(hello).title("Hello World!"));

mMap.moveCamera(CameraUpdateFactory.newLatLng(hello));

So whilst all the answers here are good I wanted a bit more control over the output. For instance I'd like to prevent any near white shades, whilst ensuring I get bright vibrant colours not washed out shades.

function generateColor(ranges) {
            if (!ranges) {
                ranges = [
                    [150,256],
                    [0, 190],
                    [0, 30]
                ];
            }
            var g = function() {
                //select random range and remove
                var range = ranges.splice(Math.floor(Math.random()*ranges.length), 1)[0];
                //pick a random number from within the range
                return Math.floor(Math.random() * (range[1] - range[0])) + range[0];
            }
            return "rgb(" + g() + "," + g() + "," + g() +")";
        };

So now I can specify 3 arbitrary ranges to pick rgb values from. You can call it with no arguments and get my default set which will usually generate a quite vibrant colour with once obvious dominant shade, or you can supply your own array of ranges.

I use:

Membership.GetUser().UserName

I am not sure this will work in ASP.NET MVC, but it's worth a shot :)

I think you can't do that but atleast you can update it. In order to edit an existing row in a DataTable, you need to locate the DataRow you want to edit, and then assign the updated values to the desired columns.

Example,

DataSet1.Tables(0).Rows(4).Item(0) = "Updated Company Name"
DataSet1.Tables(0).Rows(4).Item(1) = "Seattle"

SOURCE HERE

Best way is to use a function:

#include <map>

using namespace std;

map<int,int> create_map()
{
  map<int,int> m;
  m[1] = 2;
  m[3] = 4;
  m[5] = 6;
  return m;
}

map<int,int> m = create_map();

You need to use ListBox.ItemContainerStyle.

ListBox.ItemTemplate specifies how the content of an item should be displayed. But WPF still wraps each item in a ListBoxItem control, which by default gets its Background set to the system highlight colour if it is selected. You can't stop WPF creating the ListBoxItem controls, but you can style them -- in your case, to set the Background to always be Transparent or Black or whatever -- and to do so, you use ItemContainerStyle.

juFo's answer shows one possible implementation, by "hijacking" the system background brush resource within the context of the item style; another, perhaps more idiomatic technique is to use a Setter for the Background property.

In my current organization, we don't do this in master but do do it on both develop and release/ branches (we are using Git Flow), in order to generate snapshot builds.

As we are using a multi branch pipeline, we do this in the Jenkinsfile with the when{} syntax...

stage {
    when { 
        expression { 
            branch 'develop'
        }
    }
}

This is detailed in this blog post: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/#longer-pipeline

It's not possible to decrypt MD5 hash which created. You need all information to decrypt the MD5 value which was used during encryption.

You can use AES algorithm to encrypt and decrypt

JavaScript AES encryption and decryption (Advanced Encryption Standard)

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

Convert.ChangeType() doesn't correctly handle nullable types or enumerations in .NET 2.0 BCL (I think it's fixed for BCL 4.0 though). Rather than make the outer implementation more complex, make the converter do more work for you. Here's an implementation I use:

public static class Converter
{
  public static T ConvertTo<T>(object value)
  {
    return ConvertTo(value, default(T));
  }

  public static T ConvertTo<T>(object value, T defaultValue)
  {
    if (value == DBNull.Value)
    {
      return defaultValue;
    }
    return (T) ChangeType(value, typeof(T));
  }

  public static object ChangeType(object value, Type conversionType)
  {
    if (conversionType == null)
    {
      throw new ArgumentNullException("conversionType");
    }

    // if it's not a nullable type, just pass through the parameters to Convert.ChangeType
    if (conversionType.IsGenericType && conversionType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
    {
      // null input returns null output regardless of base type
      if (value == null)
      {
        return null;
      }

      // it's a nullable type, and not null, which means it can be converted to its underlying type,
      // so overwrite the passed-in conversion type with this underlying type
      conversionType = Nullable.GetUnderlyingType(conversionType);
    }
    else if (conversionType.IsEnum)
    {
      // strings require Parse method
      if (value is string)
      {
        return Enum.Parse(conversionType, (string) value);          
      }
      // primitive types can be instantiated using ToObject
      else if (value is int || value is uint || value is short || value is ushort || 
           value is byte || value is sbyte || value is long || value is ulong)
      {
        return Enum.ToObject(conversionType, value);
      }
      else
      {
        throw new ArgumentException(String.Format("Value cannot be converted to {0} - current type is " +
                              "not supported for enum conversions.", conversionType.FullName));
      }
    }

    return Convert.ChangeType(value, conversionType);
  }
}

Then your implementation of GetQueryString<T> can be:

public static T GetQueryString<T>(string key)
{
    T result = default(T);
    string value = HttpContext.Current.Request.QueryString[key];

    if (!String.IsNullOrEmpty(value))
    {
        try
        {
            result = Converter.ConvertTo<T>(value);  
        }
        catch
        {
            //Could not convert.  Pass back default value...
            result = default(T);
        }
    }

    return result;
}

If you're only interested in international numbers and you'd like to be able to show the flag of the country that matches the country code in the input, I wrote a small library for that:

https://github.com/tfcporciuncula/phonemoji

Here's how it looks:

Add this class to your css file to override the bootstrap class.modal-header

.modal-header {
   background:#0480be;
}

It's important try to never edit Bootstrap CSS, in order to be able to update from the repo and not loose the changes made or break something in futures releases.

Didnt work for me.

I created a new key and string value and managed to get it working

Key= HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\<Your app name>\
String EventMessageFile value=C:\Windows\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll

When using WebAPI, you should just return the Object rather than specifically returning Json, as the API will either return JSON or XML depending on the request.

I am not sure why your WebAPI is returning an ActionResult, but I would change the code to something like;

public IEnumerable<ListItems> GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return result;
}

This will result in JSON if you are calling it from some AJAX code.

P.S WebAPI is supposed to be RESTful, so your Controller should be called ListItemController and your Method should just be called Get. But that is for another day.

I propose an alternative method using seaborn

Working code:

import pandas as pd
import seaborn as sns
data=np.random.rand(10,2)*100
df = pd.DataFrame(data, columns=['A', 'B'])
ax= sns.lineplot(data=df, markers= True)
ax.set(xlabel='xlabel', ylabel='ylabel', title='title')
#changing ylables ticks
y_value=['{:,.2f}'.format(x) + '%' for x in ax.get_yticks()]
ax.set_yticklabels(y_value)

word of warning: the prefs:root or App-Prefs:root URL schemes are considered private API. Apple may reject you app if you use those, here is what you may get when submitting your app:

Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change. Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.

Next Steps

To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.

If there are no alternatives for providing the functionality your app requires, you can file an enhancement request.

For strings like that, for me the most comfortable way to do it is doubling the ' or ", as explained in the MySQL manual:

There are several ways to include quote characters within a string:

A “'” inside a string quoted with “'” may be written as “''”.

A “"” inside a string quoted with “"” may be written as “""”.

Precede the quote character by an escape character (“\”).

A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a

Strings quoted with “'” need no special treatment.
