Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

As @PaulTheCyclist says, If using IISExpress anonymous authentication is enabled by default, windows authentication is disabled.

This can be changed in what I'm sure used to be called PropertyPages (NOT right-click -> properties). Select the web project

Just insert <input> element in <td> dynamically, on cell click. Only simple HTML and Javascript. No need for contentEditable , jquery, HTML5

https://Jsfiddle.net/gsivanov/38tLqobw/2/

var id = "id" + Math.random().toString(16).slice(2)

use numpy fancy indexing:

In [29]: countries=np.asarray(countries)

In [30]: countries[countries!='nan']
Out[30]: 
array(['USA', 'UK', 'France'], 
      dtype='|S6')

dochoffiday's answer is a great starting point, but for me it did not cut it (the CSS part needed a buff) so I made a modified version with several improvements.

See it in action, then come back for the description.

JavaScript

(function ($) {
    $.fn.styleTable = function (options) {
        var defaults = {
            css: 'ui-styled-table'
        };
        options = $.extend(defaults, options);

        return this.each(function () {
            $this = $(this);
            $this.addClass(options.css);

            $this.on('mouseover mouseout', 'tbody tr', function (event) {
                $(this).children().toggleClass("ui-state-hover",
                                               event.type == 'mouseover');
            });

            $this.find("th").addClass("ui-state-default");
            $this.find("td").addClass("ui-widget-content");
            $this.find("tr:last-child").addClass("last-child");
        });
    };
})(jQuery);

Differences with the original version:

• the default CSS class has been changed to ui-styled-table (it sounds more consistent)
• the .live call was replaced with the recommended .on for jQuery 1.7 upwards
• the explicit conditional has been replaced by .toggleClass (a terser equivalent)
• code that sets the misleadingly-named CSS class first on table cells has been removed
• the code that dynamically adds .last-child to the last table row is necessary to fix a visual glitch on Internet Explorer 7 and Internet Explorer 8; for browsers that support :last-child it is not necessary

CSS

/* Internet Explorer 7: setting "separate" results in bad visuals; all other browsers work fine with either value. */
/* If set to "separate", then this rule is also needed to prevent double vertical borders on hover:
table.ui-styled-table tr * + th, table.ui-styled-table tr * + td  { border-left-width: 0px !important; } */
table.ui-styled-table { border-collapse: collapse; }

/* Undo the "bolding" that jQuery UI theme may cause on hovered elements
/* Internet Explorer 7: does not support "inherit", so use a MS proprietary expression along with an Internet Explorer <= 7 targeting hack
        to make the visuals consistent across all supported browsers */
table.ui-styled-table td.ui-state-hover {
    font-weight: inherit;
    *font-weight: expression(this.parentNode.currentStyle['fontWeight']);
}

/* Initally remove bottom border for all cells. */
table.ui-styled-table th, table.ui-styled-table td { border-bottom-width: 0px !important; }

/* Hovered-row cells should show bottom border (will be highlighted) */
table.ui-styled-table tbody tr:hover th,
table.ui-styled-table tbody tr:hover td
{ border-bottom-width: 1px !important; }

/* Remove top border if the above row is being hovered to prevent double horizontal borders. */
table.ui-styled-table tbody tr:hover + tr th,
table.ui-styled-table tbody tr:hover + tr td
{ border-top-width: 0px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 7, Internet Explorer 8: selector dependent on CSS classes because of no support for :last-child */
table.ui-styled-table tbody tr.last-child th,
table.ui-styled-table tbody tr.last-child td
{ border-bottom-width: 1px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 8 BUG: if these (unsupported) selectors are added to a rule, other selectors for that rule will stop working as well! */
/* Internet Explorer 9 and later, Firefox, Chrome: make sure the visuals are working even without the CSS classes crutch. */
table.ui-styled-table tbody tr:last-child th,
table.ui-styled-table tbody tr:last-child td
{ border-bottom-width: 1px !important; }

Notes

I have tested this on Internet Explorer 7 and upwards, Firefox 11 and Google Chrome 18 and confirmed that it works perfectly. I have not tested reasonably earlier versions of Firefox and Chrome or any version of Opera; however, those browsers are well-known for good CSS support and since we are not using any bleeding-edge functionality here I assume it will work just fine there as well.

If you are not interested in Internet Explorer 7 support there is one CSS attribute (introduced with the star hack) that can go.

If you are not interested in Internet Explorer 8 support either, the CSS and JavaScript related to adding and targeting the last-child CSS class can go as well.

In the case of a non blocking socket that has no data available, recv will throw the socket.error exception and the value of the exception will have the errno of either EAGAIN or EWOULDBLOCK. Example:

import sys
import socket
import fcntl, os
import errno
from time import sleep

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1',9999))
fcntl.fcntl(s, fcntl.F_SETFL, os.O_NONBLOCK)

while True:
    try:
        msg = s.recv(4096)
    except socket.error, e:
        err = e.args[0]
        if err == errno.EAGAIN or err == errno.EWOULDBLOCK:
            sleep(1)
            print 'No data available'
            continue
        else:
            # a "real" error occurred
            print e
            sys.exit(1)
    else:
        # got a message, do something :)

The situation is a little different in the case where you've enabled non-blocking behavior via a time out with socket.settimeout(n) or socket.setblocking(False). In this case a socket.error is stil raised, but in the case of a time out, the accompanying value of the exception is always a string set to 'timed out'. So, to handle this case you can do:

import sys
import socket
from time import sleep

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1',9999))
s.settimeout(2)

while True:
    try:
        msg = s.recv(4096)
    except socket.timeout, e:
        err = e.args[0]
        # this next if/else is a bit redundant, but illustrates how the
        # timeout exception is setup
        if err == 'timed out':
            sleep(1)
            print 'recv timed out, retry later'
            continue
        else:
            print e
            sys.exit(1)
    except socket.error, e:
        # Something else happened, handle error, exit, etc.
        print e
        sys.exit(1)
    else:
        if len(msg) == 0:
            print 'orderly shutdown on server end'
            sys.exit(0)
        else:
            # got a message do something :)

As indicated in the comments, this is also a more portable solution since it doesn't depend on OS specific functionality to put the socket into non-blockng mode.

See recv(2) and python socket for more details.

If you install WAMPServer before you install the C++ Redistributable, it won't work even after you've installed it because you will miss a critical step in the installation where you tell Windows Firewall to let Apache run.

1. Uninstall WAMP by running the unins file in the wamp directory
2. Download and install the vbasic package here [http://www.microsoft.com/en-us/download/details.aspx?id=8328]
3. Restart your computer
4. Install WAMP again. You should see a message with a purple feather telling you to allow access. Do so, and you should be all good

When we try to add an object to the arraylist,

Java checks to ensure that there is enough capacity in the existing array to hold the new object. If not, a new array of a greater size is created, the old array is copied to new array using Arrays.copyOf and the new array is assigned to the existing array.

Look at the code below (taken from Java ArrayList Code at GrepCode.com).

Edit:

public ArrayList() Constructs an empty list with an initial capacity of ten.

public ArrayList(int initialCapacity) we can specify initial capacity.

public ArrayList(Collection c) Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Now when we use ArrayList() constructore we get a ArrayList with Size=10 On adding 11th element in the list new Arraylist is created inside ensureCapacity() method.

Using following formula:

  int newCapacity= (oldCapacity * 3)/2 +1;

PHP.net explanation about MAX_FILE_SIZE hidden field.

The MAX_FILE_SIZE hidden field (measured in bytes) must precede the file input field, and its value is the maximum filesize accepted by PHP. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too large and the transfer failed. Keep in mind: fooling this setting on the browser side is quite easy, so never rely on files with a greater size being blocked by this feature. It is merely a convenience feature for users on the client side of the application. The PHP settings (on the server side) for maximum-size, however, cannot be fooled.

http://php.net/manual/en/features.file-upload.post-method.php

You could use JavaScript. Either put the code inline, into a function or use jQuery.

1. Inline:

   <a href="deletelink" onclick="return confirm('Are you sure?')">Delete</a>
   

2. In a function:

   <a href="deletelink" onclick="return checkDelete()">Delete</a>
   

   and then put this in <head>:

   <script language="JavaScript" type="text/javascript">
   function checkDelete(){
       return confirm('Are you sure?');
   }
   </script>
   

   This one has more work, but less file size if the list is long.

3. With jQuery:

   <a href="deletelink" class="delete">Delete</a>
   

   And put this in <head>:

   <script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
   <script language="JavaScript" type="text/javascript">
   $(document).ready(function(){
       $("a.delete").click(function(e){
           if(!confirm('Are you sure?')){
               e.preventDefault();
               return false;
           }
           return true;
       });
   });
   </script>
   

It's a weird design, but the TableLayoutPanel.RowCount property doesn't reflect the count of the RowStyles collection, and similarly for the ColumnCount property and the ColumnStyles collection.

What I've found I needed in my code was to manually update RowCount/ColumnCount after making changes to RowStyles/ColumnStyles.

Here's an example of code I've used:

    /// <summary>
    /// Add a new row to our grid.
    /// </summary>
    /// The row should autosize to match whatever is placed within.
    /// <returns>Index of new row.</returns>
    public int AddAutoSizeRow()
    {
        Panel.RowStyles.Add(new RowStyle(SizeType.AutoSize));
        Panel.RowCount = Panel.RowStyles.Count;
        mCurrentRow = Panel.RowCount - 1;
        return mCurrentRow;
    }

Other thoughts

• I've never used DockStyle.Fill to make a control fill a cell in the Grid; I've done this by setting the Anchors property of the control.

• If you're adding a lot of controls, make sure you call SuspendLayout and ResumeLayout around the process, else things will run slow as the entire form is relaid after each control is added.

I use setdefault() when I want a default value in an OrderedDict. There isn't a standard Python collection that does both, but there are ways to implement such a collection.

Note that On Error Resume Next is not set globally. You can put your unsafe part of code eg into a function, which will interrupted immediately if error occurs, and call this function from sub containing precedent OERN statement.

ErrCatch()

Sub ErrCatch()
    Dim Res, CurrentStep

    On Error Resume Next

    Res = UnSafeCode(20, CurrentStep)
    MsgBox "ErrStep " & CurrentStep & vbCrLf & Err.Description

End Sub

Function UnSafeCode(Arg, ErrStep)

    ErrStep = 1
    UnSafeCode = 1 / (Arg - 10)

    ErrStep = 2
    UnSafeCode = 1 / (Arg - 20)

    ErrStep = 3
    UnSafeCode = 1 / (Arg - 30)

    ErrStep = 0
End Function

You need to install Python's header files (python-dev package in debian/ubuntu) to compile lxml. As well as libxml2, libxslt, libxml2-dev, and libxslt-dev:

apt-get install python-dev libxml2 libxml2-dev libxslt-dev

Had the same problem.

long milliseconds = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;

This is actually how the various Unix conversion methods are implemented in the DateTimeOffset class (.NET Framework 4.6+, .NET Standard 1.3+):

long milliseconds = DateTimeOffset.Now.ToUnixTimeMilliseconds();

The easiest way I have found to have the proper "directory" structure appear under the drawable folder for my icons is this:

1. Right click "Drawable"
2. Click on "New", then "Image Asset"
3. Change "Asset Type" to "Action Bar and Tab Icons"
4. For "Foreground" choose "ClipArt"
5. For "Clipart" click and "Choose" button and pick any icon
6. For "Resource Name" type in you icon file name

Now the pseudo-directories have been created for you under the Drawable folder in the Android view. Open up the true directories on your file system "main/res/drawable-xxhdpi", "main/res/drawable-xhdpi" and replace the icons in each folder with your own of the proper density.

It's shipped with Android Studio now. Just go to Build/Analyze APK... then select your APK :)

To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice. More info on this approach, read the Matplotlib Cookbook

However, the non-GUI-neutral (GUI-biased?) approach is key to speeding up the plotting. In other words, the backend is extremely important to plot speed.

Put these two lines before you import anything else from matplotlib:

import matplotlib
matplotlib.use('GTKAgg') 

Of course, there are various options to use instead of GTKAgg, but according to the cookbook mentioned before, this was the fastest. See the link about backends for more options.

If you want to use $.getJSON() you can add the following before the call :

$.ajaxSetup({
    scriptCharset: "utf-8",
    contentType: "application/json; charset=utf-8"
});

You can use the charset you want instead of utf-8.

The options are explained here.

contentType : When sending data to the server, use this content-type. Default is application/x-www-form-urlencoded, which is fine for most cases.

scriptCharset : Only for requests with jsonp or script dataType and GET type. Forces the request to be interpreted as a certain charset. Only needed for charset differences between the remote and local content.

You may need one or both ...

Same thing happened to me and I got it working doing this:

• Do not cancel the installation (using the cancel button), instead force showdown your computer so the process is killed and you get a reboot.
• After the reboot, just start the install process again.

This worked for me.

You can use the document.createElement() function like this:

function addScript( src ) {
  var s = document.createElement( 'script' );
  s.setAttribute( 'src', src );
  document.body.appendChild( s );
}

Since I've asked this question, I've started using python-symmetric-jsonrpc. It is quite good, can be used between python and non-python software and follow the JSON-RPC standard. But it lacks some examples.

Just in case anyone is insane like me and wants to just run typescript script as though it was a .js script, you can try this. I've written a hacky script that appears to execute the .ts script using node.

#!/usr/bin/env bash

NODEPATH="$HOME/.nvm/versions/node/v8.11.3/bin" # set path to your node/tsc

export TSC="$NODEPATH/tsc"
export NODE="$NODEPATH/node"

TSCFILE=$1 # only parameter is the name of the ts file you created.

function show_usage() {
    echo "ts2node [ts file]"
    exit 0
}

if [ "$TSCFILE" == "" ]
then
    show_usage;
fi

JSFILE="$(echo $TSCFILE|cut -d"." -f 1).js"

$TSC $TSCFILE && $NODE $JSFILE

You can do this or write your own but essentially, it creates the .js file and then uses node to run it like so:

# tsrun myscript.ts

Simple. Just make sure your script only has one "." else you'll need to change your JSFILE in a different way than what I've shown.

First of all use mysqli_connect($dbhost,$dbuser,$dbpass,$dbname)

Second - put mysqli_ everywhere instead of mysql_

Third - use this $sql = "UPDATE anstalld SET mandag = '.$mandag.', tisdag = '.$tisdag.', onsdag = '.$onsdag.', torsdag = '.$torsdag.', fredag = '.$fredag.' WHERE namn = '.$namn.'";
$retval = mysqli_query( $conn, $sql ); //execute your query

if Your data is being updated in your database but not in your table its because when you will click on update button, the request is made to the same file. It first selects the data from the database when it is not updated prints it in the table and then update it according to the flow. If you have to update it as you click on update button then put this section

<?php
if(isset($_POST['update']))
{

$namn = $_POST['namnid'];
$mandag = $_POST['mandagid'];
$tisdag = $_POST['tisdagid'];
$onsdag = $_POST['onsdagid'];
$torsdag = $_POST['torsdagid'];
$fredag = $_POST['fredagid'];

$sql = mysql_query("UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn'");

$retval = mysql_query( $sql, $conn );
if(! $retval )
{
die('Could not update data: ' . mysql_error());
}
echo "Updated data successfully\n";

}


?>`

after connecting with database.

For encoding to base64 in Angular2, you can use btoa() function.

Example:-

console.log(btoa("stringAngular2")); 
// Output:- c3RyaW5nQW5ndWxhcjI=

For decoding from base64 in Angular2, you can use atob() function.

Example:-

console.log(atob("c3RyaW5nQW5ndWxhcjI=")); 
// Output:- stringAngular2

First, you might need to edit your system's PATH

sudo vi /etc/paths

Add 2 following lines:

/opt/local/bin
/opt/local/sbin

Reboot your terminal

If you can't use $timeout due to external resources and cant use a directive due to a specific issue with timing, use broadcast.

Add $scope.$broadcast("variable_name_here"); after the desired external resource or long running controller/directive has completed.

Then add the below after your external resource has loaded.

$scope.$on("variable_name_here", function(){ 
   // DOM manipulation here
   jQuery('selector').height(); 
}

For example in the promise of a deferred HTTP request.

MyHttpService.then(function(data){
   $scope.MyHttpReturnedImage = data.image;
   $scope.$broadcast("imageLoaded");
});

$scope.$on("imageLoaded", function(){ 
   jQuery('img').height(80).width(80); 
}

Try:

$(this).prop( "disabled", true );

Use max-width property of CSS, like this :

img{
  max-width:100%;
}

Typing brew install cmake as you did installs cmake. Now you can type cmake and use it.

If typing cmake doesn’t work make sure /usr/local/bin is your PATH. You can see it with echo $PATH. If you don’t see /usr/local/bin in it add the following to your ~/.bashrc:

export PATH="/usr/local/bin:$PATH"

Then reload your shell session and try again.

(all the above assumes Homebrew is installed in its default location, /usr/local. If not you’ll have to replace /usr/local with $(brew --prefix) in the export line)

The first and stable debugger for MySQL is in dbForge Studio for MySQL

Normally i use a class for this:

public class ClassName
{
    public string Col1 { get; set; }
    public int Col2 { get; set; }
}

Now you can use a loop to fill a list and ToArray if you really need an array:

ClassName[] allRecords = null;
string sql = @"SELECT col1,col2
               FROM  some table";
using (var command = new SqlCommand(sql, con))
{
    con.Open();
    using (var reader = command.ExecuteReader())
    {
        var list = new List<ClassName>();
        while (reader.Read())
            list.Add(new ClassName { Col1 = reader.GetString(0), Col2 = reader.GetInt32(1) });
        allRecords = list.ToArray();
    }
}

Note that i've presumed that the first column is a string and the second an integer. Just to demonstrate that C# is typesafe and how you use the DataReader.GetXY methods.

In the process of learning C++ you will learn most of C as well. But keep in mind a lot of C++ code is not valid C. C++ was designed to be compatible with C code, so i'd say learn C++ first. Brian wrote a great answer regarding this.

SELECT timeEvent 
  FROM tbEvents 
 WHERE CONVERT(VARCHAR,startHour,108) >= '01:01:01'

This tells SQL Server to convert the current date/time into a varchar using style 108, which is "hh:mm:ss". You can also replace '01:01:01' which another convert if necessary.

Consider this CodeProject article/project: LINQ TO CSV.

It will enable you to create a custom class that is shaped like your .csv file's columns. You'd then consume the CSV and bind to your DataGridView.

Dim cc As new CsvContext()
Dim inputFileDescription As New CsvFileDescription() With { _
    .SeparatorChar = ","C, _
    .FirstLineHasColumnNames = True _
}

Dim products As IEnumerable(Of Product) = _
     cc.Read(Of Product)("products.csv", inputFileDescription)

' query from CSV, load into a new class of your own   
Dim productsByName = From p In products
    Select New CustomDisplayClass With _
       {.Name = p.Name, .SomeDate = p.SomeDate, .Price = p.Price}, _        
    Order By p.Name


myDataGridView1.DataSource = products
myDataGridView1.DataBind()

Thanks Nicholas Carey. I was going to use regex first but what you wrote changed my mind. It is so much easier to maintain this way.

//You can set these from your custom service methods
int minLen = 8;
int minDigit 2;
int minSpChar 2;

Boolean ErrorFlag = false;
//Check for password length
if (model.NewPassword.Length < minLen)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must be at least " + minLen + " characters long.");
}

//Check for Digits and Special Characters
int digitCount = 0;
int splCharCount = 0;
foreach (char c in model.NewPassword)
{
    if (char.IsDigit(c)) digitCount++;
    if (Regex.IsMatch(c.ToString(), @"[!#$%&'()*+,-.:;<=>?@[\\\]{}^_`|~]")) splCharCount++;
}

if (digitCount < minDigit)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minDigit + " digit(s).");
}
if (splCharCount < minSpChar)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minSpChar + " special character(s).");
}

if (ErrorFlag)
    return View(model);

Consider TCP over ATM. ATM uses 48 byte frames, but clearly TCP packets can be bigger than that. A frame is the chunk of data sent as a unit over the data link (Ethernet, ATM). A packet is the chunk of data sent as a unit over the layer above it (IP). If the data link is made specifically for IP, as Ethernet and WiFi are, these will be the same size and packets will correspond to frames.

For iOS 9.1+ devices, the Xcode version should be upgraded to 7.1 (even 7.0x will not work)

update-java-alternatives

The java executable is not found with your JAVA_HOME, it only depends on your PATH.

update-java-alternatives is a good way to manage it for the entire system is through:

update-java-alternatives -l

Sample output:

java-7-oracle 1 /usr/lib/jvm/java-7-oracle
java-8-oracle 2 /usr/lib/jvm/java-8-oracle

Choose one of the alternatives:

sudo update-java-alternatives -s java-7-oracle

Like update-alternatives, it works through symlink management. The advantage is that is manages symlinks to all the Java utilities at once: javac, java, javap, etc.

I am yet to see a JAVA_HOME effect on the JDK. So far, I have only seen it used in third-party tools, e.g. Maven.

Fastest approach, if you need to perform more than just one or two such removal operations (or even just one, but on a very long string!-), is to rely on the translate method of strings, even though it does need some prep:

>>> import string
>>> allchars = ''.join(chr(i) for i in xrange(256))
>>> identity = string.maketrans('', '')
>>> nondigits = allchars.translate(identity, string.digits)
>>> s = 'abc123def456'
>>> s.translate(identity, nondigits)
'123456'

The translate method is different, and maybe a tad simpler simpler to use, on Unicode strings than it is on byte strings, btw:

>>> unondig = dict.fromkeys(xrange(65536))
>>> for x in string.digits: del unondig[ord(x)]
... 
>>> s = u'abc123def456'
>>> s.translate(unondig)
u'123456'

You might want to use a mapping class rather than an actual dict, especially if your Unicode string may potentially contain characters with very high ord values (that would make the dict excessively large;-). For example:

>>> class keeponly(object):
...   def __init__(self, keep): 
...     self.keep = set(ord(c) for c in keep)
...   def __getitem__(self, key):
...     if key in self.keep:
...       return key
...     return None
... 
>>> s.translate(keeponly(string.digits))
u'123456'
>>> 

I had this requirement recently and used other posts from this question to create this script:

$("select[multiple]").each(function() {
  $(this).css("height","100%")
    .attr("size",this.length);
})

return sentence.replaceAll("\s",".");

If you just want to check if a string is all digits (without being within a particular number range) you can use:

string test = "123";
bool allDigits = test.All(char.IsDigit);

When you start Android studio Look for Profile or Debug apk.

After clicking you get the option to browse for the saved apk and you will be bale to later run it using emulator

Multiline version (e.g. if you need to add comment after each line):

a = if b # a depends on b
then 5   # b is true 
else 10  # b is false

You could also use tools provided by the base JRE:

String msg = "<message>HELLO!</message>";
DocumentBuilder newDocumentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document parse = newDocumentBuilder.parse(new ByteArrayInputStream(msg.getBytes()));
System.out.println(parse.getFirstChild().getTextContent());

Maybe you can use arrow function (ES6+) or the simple old function declaration.

Normal function declaration type (Not ES6+):

<link href="#" onClick={function(event){ func1(event); func2();}}>Trigger here</link>

Anonymous function or arrow function type (ES6+)

<link href="#" onClick={(event) => { func1(event); func2();}}>Trigger here</link>

The second one is the shortest road that I know. Hope it helps you!

For completely transparent color, use:

rbga(255,255,255,0)

A little more visible:

rbga(255,255,255,.3)

Use this code so that the dialog activity won't be closed when the user touches outside the dialog box:

File capabilities are not ideal, because they can break after a package update.

The ideal solution, IMHO, should be an ability to create a shell with inheritable CAP_NET_BIND_SERVICE set.

Here's a somewhat convoluted way to do this:

sg $DAEMONUSER "capsh --keep=1 --uid=`id -u $DAEMONUSER` \
     --caps='cap_net_bind_service+pei' -- \
     YOUR_COMMAND_GOES_HERE"

capsh utility can be found in libcap2-bin package in Debian/Ubuntu distributions. Here's what goes on:

• sg changes effective group ID to that of the daemon user. This is necessary because capsh leaves GID unchanged and we definitely do not want it.
• Sets bit 'keep capabilities on UID change'.
• Changes UID to $DAEMONUSER
• Drops all caps (at this moment all caps are still present because of --keep=1), except inheritable cap_net_bind_service
• Executes your command ('--' is a separator)

The result is a process with specified user and group, and cap_net_bind_service privileges.

As an example, a line from ejabberd startup script:

sg $EJABBERDUSER "capsh --keep=1 --uid=`id -u $EJABBERDUSER` --caps='cap_net_bind_service+pei' -- $EJABBERD --noshell -detached"

You can give everybody execute permission:

GRANT Execute on [dbo].your_object to [public]

"Public" is the default database role that all users are a member of.

To find in the parent of the iFrame use:

$('#parentPrice', window.parent.document).html();

The second parameter for the $() wrapper is the context in which to search. This defaults to document.

The following is the right way to alter topic config as of Kafka 0.10.2.0:

When you convert your string to a date you need to match the date mask to the format in the string. This includes a time element, which you need to remove with truncation:

select 
    p1.PA_VALUE as StartDate,
    p2.PA_VALUE as EndDate
from WP_Work p 
LEFT JOIN PARAMETER p1 on p1.WP_ID=p.WP_ID AND p1.NAME = 'StartDate'
LEFT JOIN PARAMETER p2 on p2.WP_ID=p.WP_ID AND p2.NAME = 'Date_To'
WHERE p.TYPE = 'EventManagement2'
AND trunc(TO_DATE(p1.PA_VALUE, 'DD-MM-YYYY HH24:MI')) >= TO_DATE('25/10/2012', 'DD/MM/YYYY')
AND trunc(TO_DATE(p2.PA_VALUE, 'DD-MM-YYYY HH24:MI')) <= TO_DATE('26/10/2012', 'DD/MM/YYYY')

With me mostly it happens when I push changes to the wrong branch and realize later. And following works in most of the time.

git revert commit-hash
git push

git checkout my-other-branch
git revert revert-commit-hash
git push

1. revert the commit
2. (create and) checkout other branch
3. revert the revert

There's several different ways of doing this, with varying efficiency, depending on how good your query optimiser is, and the relative size of your two tables:

This is the shortest statement, and may be quickest if your phone book is very short:

SELECT  *
FROM    Call
WHERE   phone_number NOT IN (SELECT phone_number FROM Phone_book)

alternatively (thanks to Alterlife)

SELECT *
FROM   Call
WHERE  NOT EXISTS
  (SELECT *
   FROM   Phone_book
   WHERE  Phone_book.phone_number = Call.phone_number)

or (thanks to WOPR)

SELECT * 
FROM   Call
LEFT OUTER JOIN Phone_Book
  ON (Call.phone_number = Phone_book.phone_number)
  WHERE Phone_book.phone_number IS NULL

(ignoring that, as others have said, it's normally best to select just the columns you want, not '*')

Important Edit: This answer is outdated. Since writing it, the Visibility API (mdn, example, spec) has been introduced. It is the better way to solve this problem.

var focused = true;

window.onfocus = function() {
    focused = true;
};
window.onblur = function() {
    focused = false;
};

AFAIK, focus and blur are all supported on...everything. (see http://www.quirksmode.org/dom/events/index.html )

Here is an example of the practical significance of the difference and how it can bite you if you don't realize it (document.location being an object and document.location.href being a string):

We use MonoX Social CMS (http://mono-software.com) free version at http://social.ClipFlair.net and we wanted to add the language bar WebPart at some pages to localize them, but at some others (e.g. at discussions) we didn't want to use localization. So we made two master pages to use at all our .aspx (ASP.net) pages, in the first one we had the language bar WebPart and the other one had the following script to remove the /lng/el-GR etc. from the URLs and show the default (English in our case) language instead for those pages

<script>
  var curAddr = document.location; //MISTAKE
  var newAddr = curAddr.replace(new RegExp("/lng/[a-z]{2}-[A-Z]{2}", "gi"), "");
  if (curAddr != newAddr)
    document.location = newAddr;
</script>

But this code isn't working, replace function just returns Undefined (no exception thrown) so it tries to navigate to say x/lng/el-GR/undefined instead of going to url x. Checking it out with Mozilla Firefox's debugger (F12 key) and moving the cursor over the curAddr variable it was showing lots of info instead of some simple string value for the URL. Selecting Watch from that popup you could see in the watch pane it was writing "Location -> ..." instead of "..." for the url. That made me realize it was an object

One would have expected replace to throw an exception or something, but now that I think of it the problem was that it was trying to call some non-existent "replace" method on the URL object which seems to just give back "undefined" in Javascript.

The correct code in that case is:

<script>
  var curAddr = document.location.href; //CORRECT
  var newAddr = curAddr.replace(new RegExp("/lng/[a-z]{2}-[A-Z]{2}", "gi"), "");
  if (curAddr != newAddr)
    document.location = newAddr;
</script>

Take a look at PEP-238: Changing the Division Operator

The // operator will be available to request floor division unambiguously.

Unfortunately — but not surprisingly — the solution is more complicated than one would wish it to be. Also unfortunately, you'll need to use additional divs around the div you want vertically centered.

For standards-compliant browsers like Mozilla, Opera, Safari, etc. you need to set the outer div to be displayed as a table and the inner div to be displayed as a table-cell — which can then be vertically centered. For Internet Explorer, you need to position the inner div absolutely within the outer div and then specify the top as 50%. The following pages explain this technique well and provide some code samples too:

• Vertical Centering in CSS
• Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (no longer live)
• Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (Archived article courtesy of the Wayback Machine)

There is also a technique to do the vertical centering using JavaScript. Vertical alignment of content with JavaScript & CSS demonstrates it.

it is not possible to import js file inside another js file

The way to use jquery inside js is

import the js in the html or whatever view page you are using inside which you are going to include the js file

view.html

 <script src="<%=request.getContextPath()%>/js/jquery-1.11.3.js"></script>
 <script src="<%=request.getContextPath()%>/js/default.js"></script>

default.js

$('document').ready(function() {
    $('li#user').click(function() {
         $(this).addClass('selectedEmp');
    });
});

this will definitely work for you

You have to define your static member outside the class definition and provide the initializer there.

First

// In a header file (if it is in a header file in your case)
class A {   
private:      
  static const string RECTANGLE;
};

and then

// In one of the implementation files
const string A::RECTANGLE = "rectangle";

The syntax you were originally trying to use (initializer inside class definition) is only allowed with integral and enum types.

Starting from C++17 you have another option, which is quite similar to your original declaration: inline variables

// In a header file (if it is in a header file in your case)
class A {   
private:      
  inline static const string RECTANGLE = "rectangle";
};

No additional definition is needed.

Starting from C++20 instead of const you can declare it constexpr in this variant. Explicit inline would no longer be necessary, since constexpr implies inline.

append on an ndarray is ambiguous; to which axis do you want to append the data? Without knowing precisely what your data looks like, I can only provide an example using numpy.concatenate that I hope will help:

import numpy as np

pixels = np.array([[3,3]])
pix = [4,4]
pixels = np.concatenate((pixels,[pix]),axis=0)

# [[3 3]
#  [4 4]]

demo: http://jsfiddle.net/nessajtr/yxpM5/1/

var clickOver = clickOver || {};
clickOver.uniqueId = $.now();

clickOver.ClickOver = function (selector, options) {
    var self = this;

    //default values
    var isVisible, clickedAway = false;

    var callbackMethod = options.content;
var uniqueDiv = document.createElement("div");
var divId = uniqueDiv.id = ++clickOver.uniqueId;
uniqueDiv.innerHTML = options.loadingContent();

options.trigger = 'manual';
options.animation = false;
options.content = uniqueDiv;

self.onClose = function () {
    $("#" + divId).html(options.loadingContent());
    $(selector).popover('hide')
    isVisible = clickedAway = false;
};
self.onCallback = function (result) {
    $("#" + divId).html(result);
};

$(selector).popover(options);

//events
$(selector).bind("click", function (e) {
    $(selector).filter(function (f) {
        return $(selector)[f] != e.target;
    }).popover('hide');

    $(selector).popover("show");
    callbackMethod(self.onCallback);

    isVisible = !(clickedAway = false);
});

$(document).bind("click", function (e) {
    if (isVisible && clickedAway && $(e.target).parents(".popover").length == 0) {
        self.onClose();
        isVisible = clickedAway = false;
    } else clickedAway = true;
});

}

this is my solution for it.

I got some better solutions:

gc log.txt -ReadCount 5 | %{$_;throw "pipeline end!"} # head
gc log.txt | %{$num=0;}{$num++;"$num $_"}             # cat -n
gc log.txt | %{$num=0;}{$num++; if($num -gt 2 -and $num -lt 7){"$num $_"}} # sed

Error and Exception both extend Throwable, but mostly Error is thrown by JVM in a scenario which is fatal and there is no way for the application program to recover from that error. For instance OutOfMemoryError.

Though even application can raise an Error but its just not a good a practice, instead applications should use checked exceptions for recoverable conditions and runtime exceptions for programming errors.

Next Class:

public class AppLocationService extends Service implements LocationListener {

protected LocationManager locationManager;
Location location;

private static final long MIN_DISTANCE_FOR_UPDATE = 10;
private static final long MIN_TIME_FOR_UPDATE = 1000 * 60 * 2;

}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {

Don't forget to add in your manifest.

<!-- to get location using GPS -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<!-- to get location using NetworkProvider -->
<uses-permission android:name="android.permission.INTERNET" />

This fixed it for me: Open maven projects tab on the right. Add the pom if not yet present, then click refresh on the top left of the tab.

You can generate views and controllers for devise customization.

Use

rails g devise:controllers users -c=registrations

and

rails g devise:views 

It will copy particular controllers and views from gem to your application.

Next, tell the router to use this controller:

devise_for :users, :controllers => {:registrations => "users/registrations"}

vs2017 just added in these lines to csproj.user file

    <IISExpressAnonymousAuthentication>enabled</IISExpressAnonymousAuthentication>
    <IISExpressWindowsAuthentication>enabled</IISExpressWindowsAuthentication>
    <IISExpressUseClassicPipelineMode>false</IISExpressUseClassicPipelineMode>

with these lines in Web.config

<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" maxRequestLength="1048576" />
<identity impersonate="false" />
<authentication mode="Windows" />

  <allow users="yourNTusername" />
  <deny users="?" />
</authorization>

And it worked

I was testing a function that had multiple UPDATE statements within IF-ELSE blocks.

I was testing all possible paths, so I reset the tables to their previous values with 'manual' UPDATE statements each time before running the function again.

I noticed that the issue would happen just after those UPDATE statements;

I added a COMMIT; after the UPDATE statement I used to reset the tables and that solved the problem.

So, caution, the problem was not the function itself...

The good part is we can make basic maths directly:

let nuts = 7_x000D_
_x000D_
more.innerHTML = `_x000D_
_x000D_
<h2>You collected ${nuts} nuts so far!_x000D_
_x000D_
<hr>_x000D_
_x000D_
Double it, get ${nuts + nuts} nuts!!_x000D_
_x000D_
`

<div id="more"></div>

It became really useful in a factory function:

function nuts(it){_x000D_
  return `_x000D_
    You have ${it} nuts! <br>_x000D_
    Cosinus of your nuts: ${Math.cos(it)} <br>_x000D_
    Triple nuts: ${3 * it} <br>_x000D_
    Your nuts encoded in BASE64:<br> ${btoa(it)}_x000D_
  `_x000D_
}_x000D_
_x000D_
nut.oninput = (function(){_x000D_
  out.innerHTML = nuts(nut.value)_x000D_
})

<h3>NUTS CALCULATOR_x000D_
<input type="number" id="nut">_x000D_
_x000D_
<div id="out"></div>

Another option using an <a>, CSS positions and some jQuery or JS:

HTML:

<table>
<tr>
    <td>
        <span>1</span>
        <a href="#" class="rowLink"></a>
    </td>
    <td><span>2</span></td>
</tr>
</table>

CSS:

table tr td:first-child {
    position: relative;
}
a.rowLink {
    position: absolute;
    top: 0; left: 0;
    height: 30px;
}
a.rowLink:hover {
    background-color: #0679a6;
    opacity: 0.1;
}

Then you need to give the a width, using for example jQuery:

    $(function () {
        var $table = $('table');
            $links = $table.find('a.rowLink');

        $(window).resize(function () {
            $links.width($table.width());
        });

        $(window).trigger('resize');
    });

arr.sort(function(a,b) {
    a = a.toLowerCase();
    b = b.toLowerCase();
    if (a == b) return 0;
    if (a > b) return 1;
    return -1;
});

That's done for header files so that the contents only appear once in each preprocessed source file, even if it's included more than once (usually because it's included from other header files). The first time it's included, the symbol CLASS_H (known as an include guard) hasn't been defined yet, so all the contents of the file are included. Doing this defines the symbol, so if it's included again, the contents of the file (inside the #ifndef/#endif block) are skipped.

There's no need to do this for the source file itself since (normally) that's not included by any other files.

For your last question, class.h should contain the definition of the class, and declarations of all its members, associated functions, and whatever else, so that any file that includes it has enough information to use the class. The implementations of the functions can go in a separate source file; you only need the declarations to call them.

After trying almost all the solutions listed above, what finally worked for me was to create a new virtual device using a "Google APIs" image instead of a "Google Play" image.

If you've downloaded the angular.js file from Google, you need to make sure that Everyone has Read access to it, or it will not be loaded by your HTML file. By default, it seems to download with No access permissions, so you'll also be getting a message such as:

GET http://localhost/myApp/js/angular.js

This maddened me for about half an hour!

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

On CodeProject, there is an article that briefly discusses pros and cons of testing private methods. It then provides some reflection code to access private methods (similar to the code Marcus provides above.) The only issue I've found with the sample is that the code doesn't take into account overloaded methods.

You can find the article here:

http://www.codeproject.com/KB/cs/testnonpublicmembers.aspx

TextView rowTextView = (TextView)getLayoutInflater().inflate(R.layout.yourTextView, null);
        rowTextView.setText(text);
        layout.addView(rowTextView);

This is how I'm using this:

 private List<Tag> tags = new ArrayList<>();


if(tags.isEmpty()){
        Gson gson = new Gson();
        Type listType = new TypeToken<List<Tag>>() {
        }.getType();
        tags = gson.fromJson(tour.getTagsJSONArray(), listType);
    }



if (flowLayout != null) {
        if(!tags.isEmpty()) {
            Log.e(TAG, "setTags: "+ flowLayout.getChildCount() );
            flowLayout.removeAllViews();
            for (Tag tag : tags) {
                FlowLayout.LayoutParams lparams = new FlowLayout.LayoutParams(FlowLayout.LayoutParams.WRAP_CONTENT, FlowLayout.LayoutParams.WRAP_CONTENT);
                lparams.setMargins(PixelUtil.dpToPx(this, 0), PixelUtil.dpToPx(this, 5), PixelUtil.dpToPx(this, 10), PixelUtil.dpToPx(this, 5));// llp.setMargins(left, top, right, bottom);
                TextView rowTextView = (TextView) getLayoutInflater().inflate(R.layout.tag, null);
                rowTextView.setText(tag.getLabel());
                rowTextView.setLayoutParams(lparams);
                flowLayout.addView(rowTextView);
            }
        }
        Log.e(TAG, "setTags: after "+ flowLayout.getChildCount() );
    }

And this is my custom TextView named tag:

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"    
android:textSize="10dp"
android:textAllCaps="true"
fontPath="@string/font_light"
android:background="@drawable/tag_shape"
android:paddingLeft="11dp"
android:paddingTop="6dp"
android:paddingRight="11dp"
android:paddingBottom="6dp">

this is my tag_shape:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#f2f2f2" />
<corners android:radius="15dp" />
</shape>

efect:

In other place I'm adding textviews with language names from dialog with listview:

Here's my hero code. I've faced this problem. And use this code to fix this.

 USE master;

    SELECT 
        name, log_reuse_wait, log_reuse_wait_desc, is_cdc_enabled 
    FROM 
        sys.databases 
    WHERE 
        name = 'XX_System';

    SELECT DATABASEPROPERTYEX('XX_System', 'IsPublished');


    USE XX_System;
    EXEC sp_repldone null, null, 0,0,1;
    EXEC sp_removedbreplication XX_System;


    DBCC OPENTRAN;
    DBCC SQLPERF(LOGSPACE);
    EXEC sp_replcounters;



    DBCC SQLPERF(LOGSPACE);

I get this error because a field was varbinary in sqlserver table instead of varchar.

This approach resolved my issue to allow multiple domain

app.use(function(req, res, next) {
      var allowedOrigins = ['http://127.0.0.1:8020', 'http://localhost:8020', 'http://127.0.0.1:9000', 'http://localhost:9000'];
      var origin = req.headers.origin;
      if(allowedOrigins.indexOf(origin) > -1){
           res.setHeader('Access-Control-Allow-Origin', origin);
      }
      //res.header('Access-Control-Allow-Origin', 'http://127.0.0.1:8020');
      res.header('Access-Control-Allow-Methods', 'GET, OPTIONS');
      res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
      res.header('Access-Control-Allow-Credentials', true);
      return next();
    });

So easy way :

XML:

<android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff"/>
<android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Java code:

private ViewPager viewPager;

private String[] PAGE_TITLES = new String[]{
        "text1",
        "text1",
        "text3"
};
private final Fragment[] PAGES = new Fragment[]{
        new fragment1(), 
        new fragment2(),
        new fragment3()

};

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

    /**TODO ***************tebLayout*************************/
    viewPager = findViewById(R.id.viewpager);
    viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
    TabLayout tabLayout = findViewById(R.id.tab_layout);
    tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#1f57ff"));
    tabLayout.setSelectedTabIndicatorHeight((int) (4 * 
    getResources().getDisplayMetrics().density));
    tabLayout.setTabTextColors(Color.parseColor("#9d9d9d"), 
    Color.parseColor("#0d0e10"));
    tabLayout.setupWithViewPager(viewPager);
    /***************************************************************************/
    }

For those of you using Centos (and perhaps other linux distibutions), you need to make sure that its FW (iptables) allows for port 80 or any other port you want.

See here on how to completely disable it (for testing purposes only!). And here for specific rules

ListView operates based on the underlying data in the Adapter. In order to clear the ListView you need to do two things:

1. Clear the data that you set from adapter.
2. Refresh the view by calling notifyDataSetChanged

For example, see the skeleton of SampleAdapter below that extends the BaseAdapter

public class SampleAdapter extends BaseAdapter {

    ArrayList<String> data;

    public SampleAdapter() {
        this.data = new ArrayList<String>();
    }

    public int getCount() {
        return data.size();
    }

    public Object getItem(int position) {
        return data.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        // your View
        return null;
    }
}

Here you have the ArrayList<String> data as the data for your Adapter. While you might not necessary use ArrayList, you will have something similar in your code to represent the data in your ListView

Next you provide a method to clear this data, the implementation of this method is to clear the underlying data structure

public void clearData() {
    // clear the data
    data.clear();
}

If you are using any subclass of Collection, they will have clear() method that you could use as above.

Once you have this method, you want to call clearData and notifyDataSetChanged on your onClick thus the code for onClick will look something like:

// listView is your instance of your ListView
SampleAdapter sampleAdapter = (SampleAdapter)listView.getAdapter();
sampleAdapter.clearData();

// refresh the View
sampleAdapter.notifyDataSetChanged();

encountered similar issue for ubuntu/bionic64

by enabling the gui in Vagrantfile, i was able to login using default vagrant/vagrant

config.vm.provider "virtualbox" do |vb|
   vb.gui = true
end  

then reset the firewall using the following command

$ ufw force --reset  

then rebooted the system now this time without UI
was able to boot in without any issues

make sure to keep the backup of firewall rules before doing reset

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

Here's another library:

https://github.com/eltos/SimpleDialogFragments

Features color wheel and pallet picker dialogs

If you want the original URL just use the method as described by jthalborn. If you want to rebuild the url do like David Levesque explained, here is a code snippet for it:

final javax.servlet.http.HttpServletRequest req = (javax.servlet.http.HttpServletRequest) ...;
final int serverPort = req.getServerPort();
if ((serverPort == 80) || (serverPort == 443)) {
  // No need to add the server port for standard HTTP and HTTPS ports, the scheme will help determine it.
  url = String.format("%s://%s/...", req.getScheme(), req.getServerName(), ...);
} else {
  url = String.format("%s://%s:%s...", req.getScheme(), req.getServerName(), serverPort, ...);
}

You still need to consider the case of a reverse-proxy:

• request.getScheme() is returning http instead of returning https in java

Could use constants for the ports but not sure if there is a reliable source for them, default ports:

• Are HTTP and HTTPS default port numbers defined in the JDK?

Most developers will know about port 80 and 443 anyways, so constants are not that helpful.

Also see this similar post.

Using the RESTORE DATABASE command most likely. bak is a common extension used for a database backup file. You'll find documentation for this command on MSDN.

Answer above is missing an example which might not be obvious (it wasn't to me).

Url could be broken down into parts

https://github.com/liufa/Tuplinator/commit/f36e3c5b3aba23a6c9cf7c01e7485028a23c3811
                  \_____/\________/       \_______________________________________/
                   |        |                              |
            Account name    |                      Hash of revision
                        Project name              

Hash can be found here (you can click it and will get the url from browser).

Hope this saves you some time.

Windows Users need to set below paths:

• ..\Anaconda3
• ..\Anaconda3\scripts
• ..\Anaconda3\Library\bin

Per user:

1. Open Environment variable
2. Click User Variable
3. Close command prompt if already open and reopen it

System wide (requires restart):

1. Open Environment variable
2. Click System Variable
3. Restart Windows

cd myapp/trunk

I also recommend this free book, if you're just getting started with Subversion.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

There is actually only a single layer of containers. You can virtually create a "file-system" like layered storage, but in reality everything will be in 1 layer, the container in which it is.

For creating a virtual "file-system" like storage, you can have blob names that contain a '/' so that you can do whatever you like with the way you store. Also, the great thing is that you can search for a blob at a virtual level, by giving a partial string, up to a '/'.

These 2 things, adding a '/' to a path and a partial string for search, together create a virtual "file-system" storage.

There are two ways to get variable from URL in PHP:

When your URL is: http://www.example.com/index.php?id=7 you can get this id via $_GET['id'] or $_REQUEST['id'] command and store in $id variable.

Lest's take a look:

// url is www.example.com?id=7

//get id from url via $_GET['id'] command:
$id = $_GET['id']

same will be:

//get id from url via $_REQUEST['id'] command:
$id = $_REQUEST['id']

the difference is that variables can be passed to file via URL or via POST method.

if variable is passed through url, then you can get it with $_GET['variable_name'] or $_REQUEST['variable_name'] but if variable is posted, then you need to you $_POST['variable_name'] or $_REQUEST['variable_name']

So as you see $_REQUEST['variable_name'] can be used in both ways.

P.S: Also remember - never do like this: $results = mysql_query("SELECT * FROM next WHERE id=$id"); it may cause MySQL Injection and your database can be hacked.

Try to use:

$results = mysql_query("SELECT * FROM next WHERE id='".mysql_real_escape_string($id)."'");

Comparison expressions should each be in their own brackets:

{% if (a == 'foo') or (b == 'bar') %}
    ...
{% endif %}

Alternative if you are inspecting a single variable and a number of possible values:

{% if a in ['foo', 'bar', 'qux'] %}
    ...
{% endif %}

As far as I know, there's a good library called localeplanet for Localization and Internationalization in JavaScript. Furthermore, I think it's native and has no dependencies to other libraries (e.g. jQuery)

Here's the website of library: http://www.localeplanet.com/

Also look at this article by Mozilla, you can find very good method and algorithms for client-side translation: http://blog.mozilla.org/webdev/2011/10/06/i18njs-internationalize-your-javascript-with-a-little-help-from-json-and-the-server/

The common part of all those articles/libraries is that they use a i18n class and a get method (in some ways also defining an smaller function name like _) for retrieving/converting the key to the value. In my explaining the key means that string you want to translate and the value means translated string.
Then, you just need a JSON document to store key's and value's.

For example:

var _ = document.webL10n.get;
alert(_('test'));

And here the JSON:

{ test: "blah blah" }

I believe using current popular libraries solutions is a good approach.

Stumbled across this answer and I actually wanted BOTH groups (data containing that one user and data containing everything but that one user). Not necessary for the specifics of this post, but I thought I would add in case someone was googling the same issue as me.

df <- data.frame(
     ran_data1=rnorm(125),
     ran_data2=rnorm(125),
     g=rep(factor(LETTERS[1:5]), 25)
 )

test_x = split(df,df$g)[['A']]
test_y = split(df,df$g!='A')[['TRUE']]

Here's what it looks like:

head(test_x)
            x          y g
1   1.1362198  1.2969541 A
6   0.5510307 -0.2512449 A
11  0.0321679  0.2358821 A
16  0.4734277 -1.2889081 A
21 -1.2686151  0.2524744 A

> head(test_y)
            x          y g
2 -2.23477293  1.1514810 B
3 -0.46958938 -1.7434205 C
4  0.07365603  0.1111419 D
5 -1.08758355  0.4727281 E
7  0.28448637 -1.5124336 B
8  1.24117504  0.4928257 C

You can add header "Content-Type: text/html; charset=UTF-8" to your message body.

$headers = "Content-Type: text/html; charset=UTF-8";

If you use native mail() function $headers array will be the 4th parameter mail($to, $subject, $message, $headers)

If you user PEAR Mail::factory() code will be:

$smtp = Mail::factory('smtp', $params);

$mail = $smtp->send($to, $headers, $body);

I've used enumeration to handle this problem.

storage = ''
for num, value in enumerate(result, start=0):
    content = value
    if 'A' == content:
        storage = result[num + 1]

I've used num as Index here, when it finds the correct value it adds up one to the current index of actual list. Which allows me to maneuver to the next index.

I hope this helps your purpose.

t = np.array([2, 3])
t = np.append(t, [4])

One way is to add this to a new c# class or HtmlExtensions class

public static class HtmlExtensions
{
    public static MvcHtmlString Image(this HtmlHelper html, byte[] image)
    {
        var img = String.Format("data:image/jpg;base64,{0}", Convert.ToBase64String(image));
        return new MvcHtmlString("<img src='" + img + "' />");
    }
}

then you can do this in any view

@Html.Image(Model.ImgBytes)

You can't modify the references in an enumerator whilst you enumerate over it; you must keep track of the ones to remove then remove them.

This is an example of the work around:

List<string> listbox = new List<string>();
List<object> toRemove = new List<object>();

foreach (string item in listbox)
{
    string removelistitem = "OBJECT";
    if (item.Contains(removelistitem))
    {
        toRemove.Add(item);
    }
}

foreach (string item in toRemove)
{
    listbox.Remove(item);
}

But if you're using c#3.5, you could say something like this.

listbox.Items = listbox.Items.Select(n => !n.Contains("OBJECT"));

Just in case. Make sure you load the IE specific js files after you load your css files.

You are allowed to use IDs that start with a digit in your HTML5 documents:

The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.

There are no other restrictions on what form an ID can take; in particular, IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc.

But querySelector method uses CSS3 selectors for querying the DOM and CSS3 doesn't support ID selectors that start with a digit:

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.

Use a value like b22 for the ID attribute and your code will work.

Since you want to select an element by ID you can also use .getElementById method:

document.getElementById('22')

Here's how to do the same with Swift;

var valueToSave = "someValue"
NSUserDefaults.standardUserDefaults().setObject(valueToSave, forKey: "preferenceName")

To get it back later;

if let savedValue = NSUserDefaults.standardUserDefaults().stringForKey("preferenceName") {
    // Do something with savedValue
}

In Swift 3.0

var valueToSave = "someValue"
UserDefaults.standard.set(valueToSave, forKey: "preferenceName")

if let savedValue = UserDefaults.standard.string(forKey: "preferenceName") {

}

Edit (as suggested in comments and other people), Visual Studio Code has evolved and provides this functionality in-built as the command "Organize imports", with the following default keyboard shortcuts:

option+Shift+O for Mac

Alt + Shift + O for Windows

Original answer:

I hope this visual studio code extension will suffice your need: https://marketplace.visualstudio.com/items?itemName=rbbit.typescript-hero

It provides following features:

• Add imports of your project or libraries to your current file
• Add an import for the current name under the cursor
• Add all missing imports of a file with one command
• Intellisense that suggests symbols and automatically adds the needed imports "Light bulb feature" that fixes code you wrote
• Sort and organize your imports (sort and remove unused)
• Code outline view of your open TS / TSX document
• All the cool stuff for JavaScript as well! (experimental stage though, better description below.)

For Mac: control+option+o

For Win: Ctrl+Alt+o

I found a way to do it with plain old HTML and JavaScript/jQuery that degrades gracefully. Tested in IE7-10, Safari, Chrome, and FF:

HTML for download link:

<p>Thanks for downloading! If your download doesn't start shortly, 
<a id="downloadLink" href="...yourpdf.pdf" target="_blank" 
type="application/octet-stream" download="yourpdf.pdf">click here</a>.</p>

jQuery (pure JavaScript code would be more verbose) that simulates clicking on link after a small delay:

var delay = 3000;
window.setTimeout(function(){$('#downloadLink')[0].click();},delay);

To make this more robust you could add HTML5 feature detection and if it's not there then use window.open() to open a new window with the file.

Below should work.

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
Date oldDate = df.parse(df.format(date)); //this date is your old date object

You probably have some other "Date" class imported somewhere (or you have a Date class in you package, which does not need to be imported). With "import java.util.*" you are using the "other" Date. In this case it's best to explicitly specify java.util.Date in the code.

Or better, try to avoid naming your classes "Date".

I have edited the "Best answer" code, though I found a useful thing that was missing. This is will also track the ip of a user if they are using a Proxy or simply if the server has nginx installed as a proxy reverser.

I added this code to his script at the top of the function:

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

Afther that I edited his code.

Find the line that says the following:

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

and replace it with this:

$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $adresseip. $vst_id;

This will work.

Here is the full code if anything happens:

<?php

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

// Script Online Users and Visitors - http://coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();        // start Session, if not already started

$filetxt = 'userson.txt';  // the file in which the online users /visitors are stored
$timeon = 120;             // number of secconds to keep a user online
$sep = '^^';               // characters used to separate the user name and date-time
$vst_id = '-vst-';        // an identifier to know that it is a visitor, not logged user

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.

Haven't tested this on the Sql script yet.

SELECT DATEDIFF(max_date, min_date) as days from my table. This works even if the col max_date and min_date are in string data types.

Varchar Date Convert to Date and Change the Format

Nov 12 2016 12:00 , 21/12/2016, 21-12-2016 this Query Works for above to change to this Format dd/MM/yyyy SELECT [Member_ID],[Name] , Convert(varchar(50),Convert(date,[DOB],103),103) as DOB ,[NICNO],[Relation] FROM [dbo].[tbl_FamilMember]

You can try to use:

where(date: p[:date]..Float::INFINITY)

equivalent in sql

WHERE (`date` >= p[:date])

The result is:

Note.where(user_id: current_user.id, notetype: p[:note_type], date: p[:date]..Float::INFINITY).order(:fecha, :created_at)

And I have changed too

order('date ASC, created_at ASC')

For

order(:fecha, :created_at)

I currently also have that requirement of waiting for some services to be up and running before others start. Also read the suggestions here and on some other places. But most of them require that the docker-compose.yml some how has to be changed a bit. So I started working on a solution which I consider to be an orchestration layer around docker-compose itself and I finally came up with a shell script which I called docker-compose-profile. It can wait for tcp connection to a certain container even if the service does not expose any port to the host directy. The trick I am using is to start another docker container inside the stack and from there I can (usually) connect to every service (as long no other network configuration is applied). There is also waiting method to watch out for a certain log message. Services can be grouped together to be started in a single step before another step will be triggered to start. You can also exclude some services without listing all other services to start (like a collection of available services minus some excluded services). This kind of configuration can be bundled to a profile. There is a yaml configuration file called dcp.yml which (for now) has to be placed aside your docker-compose.yml file.

For your question this would look like:

command:
  aliases:
    upd:
      command: "up -d"
      description: |
        Create and start container. Detach afterword.

profiles:
  default:
    description: |
      Wait for rabbitmq before starting worker.
    command: upd
    steps:
      - label: only-rabbitmq
        only: [ rabbitmq ]
        wait:
          - 5@tcp://rabbitmq:5432
      - label: all-others

You could now start your stack by invoking

dcp -p default upd

or even simply by

dcp

as there is only a default profile to run up -d on.

There is a tiny problem. My current version does not (yet) support special waiting condition like the ony You actually need. So there is no test to send a message to rabbit.

I have been already thinking about a further waiting method to run a certain command on host or as a docker container. Than we could extend that tool by something like

...
        wait:
          - service: rabbitmq
            method: container
            timeout: 5
            image: python-test-rabbit
...

having a docker image called python-test-rabbit that does your check.

The benefit then would be that there is no need anymore to bring the waiting part to your worker. It would be isolated and stay inside the orchestration layer.

May be someone finds this helpful to use. Any suggestions are very welcome.

You can find this tool at https://gitlab.com/michapoe/docker-compose-profile

yes, it's really just a matter of showing/hiding an animated gif.

Use the collapse argument to paste:

In TorpedoQuery it look like this

Entity from = from(Entity.class);
where(from.getCode()).in("Joe", "Bob");
Query<Entity> select = select(from);

This is a Kotlin based version, assuming that the parent view is an instance of LinearLayout.

someView.layoutParams = LinearLayout.LayoutParams(100, 200)

This allows to set the width and height (100 and 200) in a single line.

You are missing, that \ is the escape character.

Look here: http://docs.python.org/reference/lexical_analysis.html at 2.4.1 "Escape Sequence"

Most importantly \n is a newline character. And \\ is an escaped escape character :D

>>> a = 'a\\\\nb'
>>> a
'a\\\\nb'
>>> print a
a\\nb
>>> a.replace('\\\\', '\\')
'a\\nb'
>>> print a.replace('\\\\', '\\')
a\nb

Since this question is gonna be clicked some day by new EF Core users and I find the top answers somewhat unnecessarily destructive, I will show you a way to start "fresh". Beware, this deletes all of your data.

1. Delete all tables on your MS SQL server. Also delete the __EFMigrations table.
2. Type dotnet ef database update
3. EF Core will now recreate the database from zero up until your latest migration.

Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.

I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.

Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.

It might be related to corruption in Angular Packages or incompatibility of packages.

Please follow the below steps to solve the issue.

• Delete node_modules folder manually.
• Install Node ( https://nodejs.org/en/download ).
• Install Yarn ( https://yarnpkg.com/en/docs/install ).
• Open command prompt , go to path angular folder and run Yarn.
• Run angular\nswag\refresh.bat.
• Run npm start from the angular folder.

Update

ASP.NET Boilerplate suggests here to use yarn because npm has some problems. It is slow and can not consistently resolve dependencies, yarn solves those problems and it is compatible to npm as well.

If you are expecting 4 as output then try this:

char a[]={0x00,0xdc,0x01,0x04};

Also, you can try (for Windows 10 Pro) Run Powershell as administrator and type ssh-keygen -t rsa -b 4096 -C "[email protected]"

You can configure the ObjectMapper as a bean in your Spring xml file. What holds a reference to the ObjectMapper is the MappingJacksonJsonView class. You then need to attach the view to a ViewResolver.

Something like this should work:

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
      <property name="mediaTypes">
      <map>
        <entry key="json" value="application/json" />
        <entry key="html" value="text/html" />
      </map>
    </property>
    <property name="viewResolvers">
      <list>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/jsp/" />
          <property name="suffix" value=".jsp" />
        </bean>
      </list>
    </property>
    <property name="defaultViews">
      <list>
        <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
          <property name="prefixJson" value="false" />
          <property name="objectMapper" value="customObjectMapper" />
        </bean>
      </list>
    </property>
  </bean>

Where customObjectMapper is defined elsewhere in the xml file. Note that you can directly set Spring property values with the Enums Jackson defines; see this question.

Also, ContentNegotiatingViewResolver probably isn't required, it's just the code I am using in an existing project.

public class MainActivity extends Activity
        implements View.OnClickListener {
    private Button btnForward, btnBackword, btnPause, btnPlay;

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

    private void initControl() {
        btnForward = (Button) findViewById(R.id.btnForward);
        btnBackword = (Button) findViewById(R.id.btnBackword);
        btnPause = (Button) findViewById(R.id.btnPause);
        btnPlay = (Button) findViewById(R.id.btnPlay);
        btnForward.setOnClickListener(this);
        btnBackword.setOnClickListener(this);
        btnPause.setOnClickListener(this);
        btnPlay.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btnForward:
                break;
            case R.id.btnBackword:
                break;
            case R.id.btnPause:
                break;
            case R.id.btnPlay:
                break;
        }
    }
}

Download dex2jar here. Create a java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

This is the best one I've found.

http://code.stephenmorley.org/php/diff-implementation/

The only illegal characters are &, < and > (as well as " or ' in attributes, depending on which character is used to delimit the attribute value: attr="must use " here, ' is allowed" and attr='must use ' here, " is allowed').

They're escaped using XML entities, in this case you want & for &.

Really, though, you should use a tool or library that writes XML for you and abstracts this kind of thing away for you so you don't have to worry about it.

I just found this built into Oracle 10g if that is what you're using. I had to strip all the special characters out for a phone number compare.

regexp_replace(c.phone, '[^0-9]', '')

Eclipse's compiler can assure that your java sources conform to a given JDK version even if you don't have that version installed. This feature is useful for ensuring backwards compatibility of your code.

Your code will still be compiled and run by the JDK you've selected.

Try the Windows event log, there can be some useful information

Addition to previous answer make sure that your curl installation supports https.
You can use curl --version to get information about supported protocols.

If your curl supports https follow the previous answer.

curl --cert certificate_path:password https://www.example.com

If it does not support https, you need to install a cURL version that supports https.

The accepted answer above:

-Duser.timezone="Europe/Sofia" 

Didn't work for me exactly. I only was able to successfully change my timezone when I didn't have quotes around the parameters:

-Duser.timezone=Europe/Sofia

There's a way to exclude specific auto-configuration classes using @SpringBootApplication annotation.

@Import(MyPersistenceConfiguration.class)
@SpringBootApplication(exclude = {
        DataSourceAutoConfiguration.class, 
        DataSourceTransactionManagerAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class})
public class MySpringBootApplication {         
    public static void main(String[] args) {
        SpringApplication.run(MySpringBootApplication.class, args);
    }
}

@SpringBootApplication#exclude attribute is an alias for @EnableAutoConfiguration#exclude attribute and I find it rather handy and useful.
I added @Import(MyPersistenceConfiguration.class) to the example to demonstrate how you can apply your custom database configuration.

If the condition I'm testing for is really bad news, I do this:

*(int*) NULL= 0;

This gives me a nice coredump from where I can examine the situation.

You could use assign, but using assign (or get) is often a symptom of a programming structure that is not very R like. Typically, lists or matrices allow cleaner solutions.

• with a list:

  A <- lapply (1 : 10, function (x) d + rnorm (3))
  

• with a matrix:

  A <- matrix (rep (d, each = 10) + rnorm (30), nrow = 10)
  

I was also facing the same problem with gradle. Now I have solved by installing the highlighted in red. To navigate on this page Open Android studio > Tool > Android > SDK Manager > Appearance & Behavior > System Settings > Android SDK > SDK Tools (from tab options) > Show Package details(check box on the right bottom corner). After installing these just refresh the gradle everything will be resolved.

Here's a solution, but I don't know if it's the best....

Select              
Coalesce(Case When Len(listing.Offer_Text) = 0 Then Null Else listing.Offer_Text End, company.Offer_Text, '') As Offer_Text,         
from tbl_directorylisting listing  
 Inner Join tbl_companymaster company            
  On listing.company_id= company.company_id

I had to solve a similar problem. I inherited a large source table from MS Access with nearly 15000 records that did not have a primary key, which I had to normalize and make CakePHP compatible. One convention of CakePHP is that every table has a the primary key, that it is first column and that it is called 'id'. The following simple statement did the trick for me under MySQL 5.5:

ALTER TABLE `database_name`.`table_name` 
ADD COLUMN `id` INT NOT NULL AUTO_INCREMENT FIRST,
ADD PRIMARY KEY (`id`);

This added a new column 'id' of type integer in front of the existing data ("FIRST" keyword). The AUTO_INCREMENT keyword increments the ids starting with 1. Now every dataset has a unique numerical id. (Without the AUTO_INCREMENT statement all rows are populated with id = 0).

I've done it like so:

((ViewManager)entry.getParent()).removeView(entry);

Quick solution in NetBeans 6.8.

In the Projects window right-click on the name of the project that lacks library -> Properties -> The Project Properties window opens. In Categories tree select "Libraries" node -> On the right side of the Project Properties window press button "Add JAR/Folder" -> Select jars you need.

You also can see my short Video How-To.

Just to add couple cents to this.

The "delete_by_query" mentioned at the top is still available as a plugin in elasticsearch 2.x.

Although in the latest upcoming version 5.x it will be replaced by "delete by query api"

I used the TryParse that @fjdumont mentioned but in the validating event instead.

private void Number_Validating(object sender, CancelEventArgs e) {
    int val;
    TextBox tb = sender as TextBox;
    if (!int.TryParse(tb.Text, out val)) {
        MessageBox.Show(tb.Tag +  " must be numeric.");
        tb.Undo();
        e.Cancel = true;
    }
}

I attached this to two different text boxes with in my form initializing code.

    public Form1() {
        InitializeComponent();
        textBox1.Validating+=new CancelEventHandler(Number_Validating);
        textBox2.Validating+=new CancelEventHandler(Number_Validating);
    }

I also added the tb.Undo() to back out invalid changes.

If you want printable ascii characters you probably should correct your code to:

if ord(char) < 32 or ord(char) > 126: return ''

this is equivalent, to string.printable (answer from @jterrace), except for the absence of returns and tabs ('\t','\n','\x0b','\x0c' and '\r') but doesnt correspond to the range on your question

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

If you're building a Rails application, you should use

Time.zone.now
Time.zone.today
Time.zone.yesterday

This gives you time or date in the timezone with which you've configured your Rails application.

For example, if you configure your application to use UTC, then Time.zone.now will always be in UTC time (it won't be impacted by the change of British Summertime for example).

Calculating relative time is easy, eg

Time.zone.now - 10.minute
Time.zone.today.days_ago(5)

How about something like

package main

import (
    "fmt"
    "time"
)

func schedule(what func(), delay time.Duration) chan bool {
    stop := make(chan bool)

    go func() {
        for {
            what()
            select {
            case <-time.After(delay):
            case <-stop:
                return
            }
        }
    }()

    return stop
}

func main() {
    ping := func() { fmt.Println("#") }

    stop := schedule(ping, 5*time.Millisecond)
    time.Sleep(25 * time.Millisecond)
    stop <- true
    time.Sleep(25 * time.Millisecond)

    fmt.Println("Done")
}

Yes. you can use SimpleDateFormat like this.

SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));

Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207

Simply try:

echo apache_request_headers()[3];

This can also be done by P/Invoking the C standard library's system function.

using System.Runtime.InteropServices;

[DllImport("msvcrt.dll")]
public static extern int system(string format);

system("copy Test.txt Test2.txt");

Output:

      1 file(s) copied.

As mentioned here, markdown do not support right aligned text or blocks. But the HTML result does it, via Cascading Style Sheets (CSS).

On my Jekyll Blog is use a syntax which works in markdown as well. To "terminate" a block use two spaces at the end or two times new line.

Of course you can also add a css-class with {: .right } instead of {: style="text-align: right" }.

Text to right

{: style="text-align: right" }
This text is on the right

Text as block

{: style="text-align: justify" }
This text is a block

    If Start + PauseTime > 86399 Then 'playing safe hence 86399

    Start = 0

    Do While Timer > 1

@geedoubleya answer is my favorite.

However, I do prefer this

if [[ -f diff.txt && -s diff.txt ]]
then
  rm -f empty.txt
  touch full.txt
elif [[ -f diff.txt && ! -s diff.txt ]]
then
  rm -f full.txt
  touch empty.txt
else
  echo "File diff.txt does not exist"
fi

For our app we had to use both these parameters access_type=offline&prompt=consent. approval_prompt=force did not work for us

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

Another pre-5.14 solution: http://www.perlmonks.org/?node_id=346719 (see japhy's post)

As his approach uses map, it also works well for arrays, but requires cascading map to produce a temporary array (otherwise the original would be modified):

my @orig = ('this', 'this sucks', 'what is this?');
my @list = map { s/this/that/; $_ } map { $_ } @orig;
# @orig unmodified

the problem is because you have got the query over multiple lines using the " " that PHP is actually sending all the white spaces in to MySQL which is causing it to error out.

Either put it on one line or append on each line :o)

Sqlyog must be trimming white spaces on each line which explains why its working.

Example:

$qr2="INSERT INTO wp_bp_activity
      (
            user_id,
 (this stuff)component,
     (is)      `type`,
    (a)        `action`,
  (problem)  content,
             primary_link,
             item_id,....

I don't see next option in a list of answers, but I can get interactive prompt with "-i" key:

$ python -i
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55)
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

Per HTML syntax, and even HTML5, the following are all valid options:

<option value="&quot;asd">test</option>
<option value="&#34;asd">test</option>
<option value='"asd'>test</option>
<option value='&quot;asd'>test</option>
<option value='&#34;asd'>test</option>
<option value=&quot;asd>test</option>
<option value=&#34;asd>test</option>

Note that if you are using XML syntax the quotes (single or double) are required.

Here's a jsfiddle showing all of the above working.

You can use the <datalist> tag instead of the <select> tag.

<input list="browsers" name="browser" id="browser">
<datalist id="browsers">
  <option value="Edge">
  <option value="Firefox">
  <option value="Chrome">
  <option value="Opera">
  <option value="Safari">
</datalist>

ncftp -u <user> -p <pass> <server>
ncftp> mget directory

Try this:

var thumbnailHold;

    $(".image_thumb").mousedown(function() {
        thumbnailHold = setTimeout(function(){
             checkboxOn(); // Your action Here

         } , 1000);
     return false;
});

$(".image_thumb").mouseup(function() {
    clearTimeout(thumbnailHold);
});

>>> 2 == 2.0
True
>>> 2 is 2.0
False

Use ==

Another approach is using UnboundID. Its api is very readable and shorter

Create a Ldap Connection

public static LDAPConnection getConnection() throws LDAPException {
    // host, port, username and password
    return new LDAPConnection("com.example.local", 389, "[email protected]", "admin");
}

Get filter result

public static List<SearchResultEntry> getResults(LDAPConnection connection, String baseDN, String filter) throws LDAPSearchException {
    SearchResult searchResult;

    if (connection.isConnected()) {
        searchResult = connection.search(baseDN, SearchScope.ONE, filter);

        return searchResult.getSearchEntries();
    }

    return null;
}

Get all Oragnization Units and Containers

String baseDN = "DC=com,DC=example,DC=local";
String filter = "(&(|(objectClass=organizationalUnit)(objectClass=container)))";

LDAPConnection connection = getConnection();        
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get a specific Organization Unit

String baseDN = "DC=com,DC=example,DC=local";
String dn = "CN=Users,DC=com,DC=example,DC=local";

String filterFormat = "(&(|(objectClass=organizationalUnit)(objectClass=container))(distinguishedName=%s))";
String filter = String.format(filterFormat, dn);

LDAPConnection connection =  getConnection();

List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get all users under an Organizational Unit

String baseDN = "CN=Users,DC=com,DC=example,DC=local";
String filter = "(&(objectClass=user)(!(objectCategory=computer)))";

LDAPConnection connection =  getConnection();       
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Get a specific user under an Organization Unit

String baseDN = "CN=Users,DC=com,DC=example,DC=local";
String userDN = "CN=abc,CN=Users,DC=com,DC=example,DC=local";

String filterFormat = "(&(objectClass=user)(distinguishedName=%s))";
String filter = String.format(filterFormat, userDN);

LDAPConnection connection =  getConnection();
List<SearchResultEntry> results = getResults(connection, baseDN, filter);

Display result

for (SearchResultEntry e : results) {
    System.out.println("name: " + e.getAttributeValue("name"));
}

private void Button1_Click(object sender, EventArgs e)
{
    NewForm newForm = new NewForm();    //Create the New Form Object
    this.Hide();    //Hide the Old Form
    newForm.ShowDialog();    //Show the New Form
    this.Close();    //Close the Old Form
}

you can set a password to your vba code but this can be quite easily broken up.

you can also create an addin and compile it into a DLL. See here for more information. That's at least the most secure way to protect your code.

Update July 1st 2019

docker-compose logs <name-of-service>

From the documentation:

Usage: logs [options] [SERVICE...]

Options:

--no-color Produce monochrome output.

-f, --follow Follow log output.

-t, --timestamps Show timestamps.

--tail="all" Number of lines to show from the end of the logs for each container.

See docker logs

You can start Docker compose in detached mode and attach yourself to the logs of all container later. If you're done watching logs you can detach yourself from the logs output without shutting down your services.

1. Use docker-compose up -d to start all services in detached mode (-d) (you won't see any logs in detached mode)
2. Use docker-compose logs -f -t to attach yourself to the logs of all running services, whereas -f means you follow the log output and the -t option gives you timestamps (See Docker reference)
3. Use Ctrl + z or Ctrl + c to detach yourself from the log output without shutting down your running containers

If you're interested in logs of a single container you can use the docker keyword instead:

1. Use docker logs -t -f <name-of-service>

Save the output

To save the output to a file you add the following to your logs command:

1. docker-compose logs -f -t >> myDockerCompose.log

Since 2020-05-07, the docker-compose spec also defines the "pull_policy" property for a service:

version: '3.7'

services:
  my-service:
    image: someimage/somewhere
    pull_policy: always

The docker-compose spec says:

pull_policy defines the decisions Compose implementations will make when it starts to pull images.

Possible values are (tl;dr, check spec for more details):

• always: always pull
• never: don't pull (breaks if the image can not be found)
• missing: pulls if the image is not cached
• build: always build or rebuild

You can use now() like:

Select data from tablename where datetime >= "01-01-2009 00:00:00" and datetime <= now();

In my case (nginx on windows proxying an app while serving static assets on its own) page was showing multiple assets including 14 bigger pictures; those errors were shown for about 5 of those images exactly after 60 seconds; in my case it was a default send_timeout of 60s making those image requests fail; increasing the send_timeout made it work

I am not sure what is causing nginx on windows to serve those files so slow - it is only 11.5MB of resources which takes nginx almost 2 minutes to serve but I guess it is subject for another thread

Timer

As mentioned on the javadocs you are better off using a ScheduledThreadPoolExecutor.

ScheduledThreadPoolExecutor

Use this class when your use case requires multiple worker threads and the sleep interval is small. How small ? Well, I'd say about 15 minutes. The AlarmManager starts schedule intervals at this time and it seems to suggest that for smaller sleep intervals this class can be used. I do not have data to back the last statement. It is a hunch.

Service

Your service can be closed any time by the VM. Do not use services for recurring tasks. A recurring task can start a service, which is another matter entirely.

BroadcastReciever with AlarmManager

For longer sleep intervals (>15 minutes), this is the way to go. AlarmManager already has constants ( AlarmManager.INTERVAL_DAY ) suggesting that it can trigger tasks several days after it has initially been scheduled. It can also wake up the CPU to run your code.

You should use one of those solutions based on your timing and worker thread needs.

There is a GUI tool available, ASoft .NET Version Detector, which has always proven highly reliable. It can create XML files by specifying the file name of the XML output on the command line.

You could use this for automation. It is a tiny program, written in a non-.NET dependent language and does not require installation.

just in case you are using a remote access and want to dump all database data, you can use:

pg_dump -a -h your_host -U your_user -W -Fc your_database > DATA.dump

it will create a dump with all database data and use

pg_restore -a -h your_host -U your_user -W -Fc your_database < DATA.dump

to insert the same data in your data base considering you have the same structure

Another way to applyhorizontalalignment and rotation to each tick label is doing a for loop over the tick labels you want to change:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]
hours_value = np.random.random(len(hours))
days_value = np.random.random(len(days))

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
axs[0].plot(hours,hours_value)
axs[1].plot(days,days_value)

for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

And here is an example if you want to control the location of major and minor ticks:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]

axs[0].plot(hours,np.random.random(len(hours)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.HourLocator(byhour = range(0,25,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[0].xaxis.set_major_locator(x_major_lct)
axs[0].xaxis.set_minor_locator(x_minor_lct)
axs[0].xaxis.set_major_formatter(x_fmt)
axs[0].set_xlabel("minor ticks set to every hour, major ticks start with 00:00")

axs[1].plot(days,np.random.random(len(days)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.DayLocator(bymonthday = range(0,32,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[1].xaxis.set_major_locator(x_major_lct)
axs[1].xaxis.set_minor_locator(x_minor_lct)
axs[1].xaxis.set_major_formatter(x_fmt)
axs[1].set_xlabel("minor ticks set to every day, major ticks show first day of month")
for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

Usage:

using (var client = new TimeoutWebClient(TimeSpan.FromSeconds(10)))
{
    return await client.DownloadStringTaskAsync(url).ConfigureAwait(false);
}

Class:

using System;
using System.Net;

namespace Utilities
{
    public class TimeoutWebClient : WebClient
    {
        public TimeSpan Timeout { get; set; }

        public TimeoutWebClient(TimeSpan timeout)
        {
            Timeout = timeout;
        }

        protected override WebRequest GetWebRequest(Uri uri)
        {
            var request = base.GetWebRequest(uri);
            if (request == null)
            {
                return null;
            }

            var timeoutInMilliseconds = (int) Timeout.TotalMilliseconds;

            request.Timeout = timeoutInMilliseconds;
            if (request is HttpWebRequest httpWebRequest)
            {
                httpWebRequest.ReadWriteTimeout = timeoutInMilliseconds;
            }

            return request;
        }
    }
}

But I recommend a more modern solution:

using System;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;

public static async Task<string> ReadGetRequestDataAsync(Uri uri, TimeSpan? timeout = null, CancellationToken cancellationToken = default)
{
    using var source = CancellationTokenSource.CreateLinkedTokenSource(cancellationToken);
    if (timeout != null)
    {
        source.CancelAfter(timeout.Value);
    }

    using var client = new HttpClient();
    using var response = await client.GetAsync(uri, source.Token).ConfigureAwait(false);

    return await response.Content.ReadAsStringAsync().ConfigureAwait(false);
}

It will throw an OperationCanceledException after a timeout.

eg:

MyPackageName is com.example.demo

MyActivityName is com.example.test.MainActivity

adb shell am start -n com.example.demo/com.example.test.MainActivity

The best solution for me was to both

• use the python binary in the venv bin/ directory
• set the python path to include the venv modules directory.

man python mentions modifying the path in shell at $PYTHONPATH or in python with sys.path

Other answers mention ideas for doing this using the shell. From python, adding the following lines to my script allows me to successfully run it directly from cron.

import sys
sys.path.insert(0,'/path/to/venv/lib/python3.3/site-packages');

Here's how it looks in an interactive session --

Python 3.3.2+ (default, Feb 28 2014, 00:52:16) 
[GCC 4.8.1] on linux
Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> sys.path
['', '/usr/lib/python3.3', '/usr/lib/python3.3/plat-x86_64-linux-gnu', '/usr/lib/python3.3/lib-dynload']

>>> import requests
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'requests'   

>>> sys.path.insert(0,'/path/to/venv/modules/');

>>> import requests
>>>

Combining several conditions:

• write mongo query in JS file and send it from terminal
• switch/define a database programmatically
• output all found records
• cut initial output lines
• save the output into JSON file

myScriptFile.js

// Switch current database to "mydatabase"
db = db.getSiblingDB('mydatabase');

// The mark for cutting initial output off
print("CUT_TO_HERE");

// Main output
// "toArray()" method allows to get all records
printjson( db.getCollection('jobs').find().toArray() );

Sending the query from terminal

-z key of sed allows treat output as a single multi-line string

$> mongo localhost --quiet myScriptFile.js | sed -z 's/^.*CUT_TO_HERE\n//' > output.json

Also I use Tomcat GUI app (in my case: C:\tomcat\bin\Tomcat9w.bin).

I don't have much experience with Flexbox but it seems to me that the forced height on the html and body tags cause the text to disappear on top when resized-- I wasn't able to test in IE but I found the same effect in Chrome.

I forked your fiddle and removed the height and width declarations.

body
{
    margin: 0;
}

It also seemed like the flex settings must be applied to other flex elements. However, applying display: flex to the .inner caused issues so I explicitly set the .inner to display: block and set the .outer to flex for positioning.

I set the minimum .outer height to fill the viewport, the display: flex, and set the horizontal and vertical alignment:

.outer
{
    display:flex;
    min-height: 100%;
    min-height: 100vh;
    align-items: center;
    justify-content: center;
}

I set .inner to display: block explicitly. In Chrome, it looked like it inherited flex from .outer. I also set the width:

.inner
{
    display:block;
    width: 80%;
}

This fixed the issue in Chrome, hopefully it might do the same in IE11. Here's my version of the fiddle: http://jsfiddle.net/ToddT/5CxAy/21/

I have had the same issue in the past (how to produce files that Excel can read, and other tools can also read). I was using TSV rather than CSV, but the same problem with encodings came up.

I failed to find any way to get Excel to recognize UTF-8 automatically, and I was not willing/able to inflict on the consumers of the files complicated instructions how to open them. So I encoded them as UTF-16le (with a BOM) instead of UTF-8. Twice the size, but Excel can recognize the encoding. And they compress well, so the size rarely (but sadly not never) matters.
