You should use tabIndex attribute to be able to listen onKeyDown event on a div in React. Setting tabIndex="0" should fire your handler.

$(window).keypress("c", function(e) {
  if (!e.ctrlKey)
    return;

  console.info("CTRL +  C detected !");
});

$(window).keypress("c", function(e) {_x000D_
  if (!e.ctrlKey)_x000D_
    return;_x000D_
_x000D_
  $("div").show();_x000D_

Figured it out by testing all the stuff by myself. Couldn't find any topics about it tho, so I'll just leave the solution here. This might not be the only or even the best solution, but it works for my purposes (within getch's limits) and is better than nothing.

Note: proper keyDown() which would recognize all the keys and actual key presses, is still valued.

Solution: using ord()-function to first turn the getch() into an integer (I guess they're virtual key codes, but not too sure) works fine, and then comparing the result to the actual number representing the wanted key. Also, if I needed to, I could add an extra chr() around the number returned so that it would convert it to a character. However, I'm using mostly down arrow, esc, etc. so converting those to a character would be stupid. Here's the final code:

from msvcrt import getch
while True:
    key = ord(getch())
    if key == 27: #ESC
        break
    elif key == 13: #Enter
        select()
    elif key == 224: #Special keys (arrows, f keys, ins, del, etc.)
        key = ord(getch())
        if key == 80: #Down arrow
            moveDown()
        elif key == 72: #Up arrow
            moveUp()

Also if someone else needs to, you can easily find out the keycodes from google, or by using python and just pressing the key:

from msvcrt import getch
while True:
    print(ord(getch()))

If you add e.SuppressKeyPress = true; as shown in the answer in this link you will suppress the annoying ding sound that occurs.

Easiest, and most Effective Method

//check key press
    function loop(){
        //>>key<< can be any string representing a letter eg: "a", "b", "ctrl",
        if(map[*key*]==true){
         //do something
        }
        //multiple keys
        if(map["x"]==true&&map["ctrl"]==true){
         console.log("x, and ctrl are being held down together")
        }
    }

//>>>variable which will hold all key information<<
    var map={}

//Key Event Listeners
    window.addEventListener("keydown", btnd, true);
    window.addEventListener("keyup", btnu, true);

    //Handle button down
      function btnd(e) {
      map[e.key] = true;
      }

    //Handle Button up
      function btnu(e) {
      map[e.key] = false;
      }

//>>>If you want to see the state of every Key on the Keybaord<<<
    setInterval(() => {
                for (var x in map) {
                    log += "|" + x + "=" + map[x];
                }
                console.log(log);
                log = "";
            }, 300);

Unfortunately, it is quite difficult to accomplish this with the arrow keys, due to restrictions in KeyDown events. However, there are a few ways to get around this:

• As @Snarfblam stated, you can override the ProcessCmdKey method, which retains the ability to parse arrow key presses.
• As the accepted answer from this question states, XNA has a built-in method called Keyboard.GetState(), which allows you to use arrow key inputs. However, WinForms doesn't have this, but it can be done through a P/Invoke, or by using a class that helps with it.

I recommend trying to use that class. It's quite simple to do so:

var left = KeyboardInfo.GetKeyState(Keys.Left);
var right = KeyboardInfo.GetKeyState(Keys.Right);
var up = KeyboardInfo.GetKeyState(Keys.Up);
var down = KeyboardInfo.GetKeyState(Keys.Down);

if (left.IsPressed)
{
//do something...
}

//etc...

If you use this in combination with the KeyDown event, I think you can reliably accomplish your goal.

If you're using the DefinitelyTyped repository in your project you might be experiencing this recent issue.

A decent workaround you might use (other than waiting for an updated build of the definitions file or refactoring your TS code) is to specify an explicit version+build for the core-js typings rather than let Visual Studio pick the latest/most recent one. I found one that seems to be unaffected by this problem (in my case at least), you can use it replacing the following line from your package.json file:

  "scripts": {
    "postinstall": "typings install dt~core-js --global"
  }

With the following one:

  "scripts": {
    "postinstall": "typings install [email protected]+20161130133742 --global"
  }

This fixed my issue for good. However, is highly recommended to remove the explicit version+build reference as soon as the issue will be released.

For further info regarding this issue, you can also read this blog post that I wrote on the topic.

Lift-json is at version 2.6 and it works really well (and is also very well supported, the maintainer is always ready to fix any bugs users may find. You can find examples using it on the github repository

The maintainer (Joni Freeman) is always reachable on the Lift mailing list. There are also other users on the mailing list who are very helpful as well.

As @Alexey points out, if you want to use the library with other Scala version, say 2.11.x, change scalaVersion and use %% as follows:

scalaVersion := "2.11.5" 

"net.liftweb" %% "lift-json" % "2.6"

You can check the liftweb.net site to find out the latest version as time goes by.

If you have a border or padding, then the solution

html, body {_x000D_
    margin: 0;_x000D_
    height: 100%;_x000D_
}_x000D_
body {_x000D_
    border: solid red 5px;_x000D_
    border-radius: 2em;_x000D_
}

produces the imperfect rendering

To get it right in the presence of a border or padding

use instead

html, body {_x000D_
    margin: 0;_x000D_
    height: 100%;_x000D_
}_x000D_
body {_x000D_
    box-sizing: border-box;_x000D_
    border: solid red 5px;_x000D_
    border-radius: 2em;_x000D_
}

as Martin pointed out, although overflow: hidden is not needed.

See the docs:

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

This error message means that you are attempting to use Python 3 to follow an example or run a program that uses the Python 2 print statement:

print "Hello, World!"

The statement above does not work in Python 3. In Python 3 you need to add parentheses around the value to be printed:

print("Hello, World!")

“SyntaxError: Missing parentheses in call to 'print'” is a new error message that was added in Python 3.4.2 primarily to help users that are trying to follow a Python 2 tutorial while running Python 3.

In Python 3, printing values changed from being a distinct statement to being an ordinary function call, so it now needs parentheses:

>>> print("Hello, World!")
Hello, World!

In earlier versions of Python 3, the interpreter just reports a generic syntax error, without providing any useful hints as to what might be going wrong:

>>> print "Hello, World!"
  File "<stdin>", line 1
    print "Hello, World!"
                        ^
SyntaxError: invalid syntax

As for why print became an ordinary function in Python 3, that didn't relate to the basic form of the statement, but rather to how you did more complicated things like printing multiple items to stderr with a trailing space rather than ending the line.

In Python 2:

>>> import sys
>>> print >> sys.stderr, 1, 2, 3,; print >> sys.stderr, 4, 5, 6
1 2 3 4 5 6

In Python 3:

>>> import sys
>>> print(1, 2, 3, file=sys.stderr, end=" "); print(4, 5, 6, file=sys.stderr)
1 2 3 4 5 6

Starting with the Python 3.6.3 release in September 2017, some error messages related to the Python 2.x print syntax have been updated to recommend their Python 3.x counterparts:

>>> print "Hello!"
  File "<stdin>", line 1
    print "Hello!"
                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Hello!")?

Since the "Missing parentheses in call to print" case is a compile time syntax error and hence has access to the raw source code, it's able to include the full text on the rest of the line in the suggested replacement. However, it doesn't currently try to work out the appropriate quotes to place around that expression (that's not impossible, just sufficiently complicated that it hasn't been done).

The TypeError raised for the right shift operator has also been customised:

>>> print >> sys.stderr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'. Did you mean "print(<message>, file=<output_stream>)"?

Since this error is raised when the code runs, rather than when it is compiled, it doesn't have access to the raw source code, and hence uses meta-variables (<message> and <output_stream>) in the suggested replacement expression instead of whatever the user actually typed. Unlike the syntax error case, it's straightforward to place quotes around the Python expression in the custom right shift error message.

<a href="#Foo" onclick="return runMyFunction();">Do it!</a>

and

function runMyFunction() {
  //code
  return true;
}

This way you will have youf function executed AND you will follow the link AND you will follow the link exactly after your function was successfully run.

very simple solution for this is by using useRef hook

const buttonRef = useRef();

const disableButton = () =>{
  buttonRef.current.disabled = true; // this disables the button
 }

<button
className="btn btn-primary mt-2"
ref={buttonRef}
onClick={disableButton}
>
    Add
</button>

Similarly you can enable the button by using buttonRef.current.disabled = false

What you want to do is actually again a groupby (on the result of the first groupby): sort and take the first three elements per group.

Starting from the result of the first groupby:

In [60]: df_agg = df.groupby(['job','source']).agg({'count':sum})

We group by the first level of the index:

In [63]: g = df_agg['count'].groupby('job', group_keys=False)

Then we want to sort ('order') each group and take the first three elements:

In [64]: res = g.apply(lambda x: x.sort_values(ascending=False).head(3))

However, for this, there is a shortcut function to do this, nlargest:

In [65]: g.nlargest(3)
Out[65]:
job     source
market  A         5
        D         4
        B         3
sales   E         7
        C         6
        B         4
dtype: int64

So in one go, this looks like:

df_agg['count'].groupby('job', group_keys=False).nlargest(3)

The underlying problem is Ctrl+Alt+Left and Right are used by window managers to switch workspace and/or OEM utilities to change the screen orientation.

You can change the assignments using File / Settings / Keymap then Main Menu / Navigate find Back and Forward and right click to Add Keyboard Shortcut to set an alternative key chord.

Alt Graph+Left and Alt Graph+Right works well for me (IDEA 13.1.4 on Ubuntu under IceWM).

This problem can be caused if a class tries to get value of a key in web.config or app.config which is not present there.

e.g.
The class has a static variable

private static string ClientID = System.Configuration.ConfigurationSettings.AppSettings["GoogleCalendarApplicationClientID"].ToString();

But the web.config doesn't contain the GoogleCalendarApplicationClientID key

The error will be thrown on any static function call or any class instance creation

you can check the type. s3 has a special application/x-directory

bucket.objects({:delimiter=>"/", :prefix=>"f1/"}).each { |obj| p obj.object.content_type }

PHP is a single-threaded language, so there is no official way to start an asynchronous process with it other than using exec or popen. There is a blog post about that here. Your idea for a queue in MySQL is a good idea as well.

Your specific requirement here is for sending an email to the user. I'm curious as to why you are trying to do that asynchronously since sending an email is a pretty trivial and quick task to perform. I suppose if you are sending tons of email and your ISP is blocking you on suspicion of spamming, that might be one reason to queue, but other than that I can't think of any reason to do it this way.

There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.

Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.

private void setUpMapIfNeeded(){
    if (mMap == null){
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();//invoke of map fragment by id from main xml file

     if (mMap != null) {
         mMap.setMyLocationEnabled(true);//Makes the users current location visible by displaying a blue dot.

         LocationManager lm=(LocationManager)getSystemService(LOCATION_SERVICE);//use of location services by firstly defining location manager.
         String provider=lm.getBestProvider(new Criteria(), true);

         if(provider==null){
             onProviderDisabled(provider);
              }
         Location loc=lm.getLastKnownLocation(provider);


         if (loc!=null){
             onLocationChanged(loc);
      }
         }
     }
}

    // Initialize map options. For example:
    // mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

@Override
public void onLocationChanged(Location location) {

   LatLng latlng=new LatLng(location.getLatitude(),location.getLongitude());// This methods gets the users current longitude and latitude.

    mMap.moveCamera(CameraUpdateFactory.newLatLng(latlng));//Moves the camera to users current longitude and latitude
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latlng,(float) 14.6));//Animates camera and zooms to preferred state on the user's current location.
}

    // TODO Auto-generated method stub

with prototype and without space :

 String.prototype.trimToLength = function (trimLenght) {
    return this.length > trimLenght ? this.substring(0, trimLenght - 3) + '...' : this
};

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

if the script fails, or downloads empty file, try removing the try wrap to see what fails

The code looks strange because the printf are not in any function blocks.

Your 2nd attempt will work perfectly, and is actually a really good way to handle variable names that you want to have available globally. But you have a name error in the last line. Here is how it should be:

# ../myproject/main.py

# Import globfile    
import globfile

# Save myList into globfile
globfile.myList = []

# Import subfile
import subfile

# Do something
subfile.stuff()
print(globfile.myList[0])

See the last line? myList is an attr of globfile, not subfile. This will work as you want.

Don't use the classes in thejava.io package, instead use the java.nio package . The latter has a FileLock class. You can apply a lock to a FileChannel.

 try {
        // Get a file channel for the file
        File file = new File("filename");
        FileChannel channel = new RandomAccessFile(file, "rw").getChannel();

        // Use the file channel to create a lock on the file.
        // This method blocks until it can retrieve the lock.
        FileLock lock = channel.lock();

        /*
           use channel.lock OR channel.tryLock();
        */

        // Try acquiring the lock without blocking. This method returns
        // null or throws an exception if the file is already locked.
        try {
            lock = channel.tryLock();
        } catch (OverlappingFileLockException e) {
            // File is already locked in this thread or virtual machine
        }

        // Release the lock - if it is not null!
        if( lock != null ) {
            lock.release();
        }

        // Close the file
        channel.close();
    } catch (Exception e) {
    }

I ran into this problem.. but within a for loop. The top solution did not work (when using variables (and not strings) for the parameters of the push function), and the others did not account for key values based on variables. I was surprised this approach (which is common in php) worked..

  // example dict/json                  
  var iterateDict = {'record_identifier': {'content':'Some content','title':'Title of my Record'},
    'record_identifier_2': {'content':'Some  different content','title':'Title of my another Record'} };

  var array = [];

  // key to reduce the 'record' to
  var reduceKey = 'title';

  for(key in iterateDict)
   // ultra-safe variable checking...
   if(iterateDict[key] !== undefined && iterateDict[key][reduceKey] !== undefined)
    // build element to new array key
     array[key]=iterateDict[key][reduceKey];

Small and universal solution:

expr "$string" : "$prefix\(.*\)$suffix"

try using this:

sqrt(sum((x1-x2)^2))

I made a blog post about NetBeans' new and upcoming support for Django. When paired with its already fantastic Python, JavaScript, HTML and CSS support, it's a strong candidate in my mind!

It is just a piece of software or a tool on which your application executes and rapplication capabilities with respect to high availability,scalability,integrating with other softwares or systems without you bothering about your application level code changes .

For example : The operating system on which your application runs requires an I.P change , you do not have to worry about it in your code , it is the middleware stack on which you can simple update the configuration.

Example 2 : You experience problems with your runtime memory allocation and feel that the your application usage has increased , you do not have to much about it unless you have a bug or bottleneck in your code , it is easily achievable by tuning middleware software configuration on which your application runs.

Example 3 : You have multiple disparate software and you need them to talk to each other or send data in a common format which is understandable by all the systems then this is where middleware systems comes handy.

Hope the information provided helps.

Possibilities:

• Use String.equals():

  if (some_string.equals("john") ||
      some_string.equals("mary") ||
      some_string.equals("peter"))
  {
  }
  

• Use a regular expression:

  if (some_string.matches("john|mary|peter"))
  {
  }
  

• Store a list of strings to be matched against in a Collection and search the collection:

  Set<String> names = new HashSet<String>();
  names.add("john");
  names.add("mary");
  names.add("peter");
  
  if (names.contains(some_string))
  {
  }
  

In my case it was the execution order of tasks ran by Grunt.

It was executing the task connect that sets up the local server and automatically opens the app in a new tab before executing less and postcss that transpile styles.

Basically, I changed this:

grunt.registerTask('default', 'Start server. Process styles.', ['connect', 'less', 'postcss']);

To this:

grunt.registerTask('default', 'Process styles. Start server.', ['less', 'postcss', 'connect']);

And it worked! Hope it helps other people too.

Prior to running python, type cd in the commmand line, and it will tell you the directory you are currently in. When python runs, it can only access files in this directory. hello.py needs to be in this directory, so you can move hello.py from its existing location to this folder as you would move any other file in Windows or you can change directories and run python in the directory hello.py is.

Edit: Python cannot access the files in the subdirectory unless a path to it provided. You can access files in any directory by providing the path. python C:\Python27\Projects\hello.p

There should be no difference, but your tuple method is wrong, try:

a_list.append(tuple([3, 4]))

Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.

Assuming you did the above, try this:

C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build

This will do several things:

• It will eliminate the possibility that the problem is with Eclipe's version of Ant.
• It is way easier to type
• Since you're executing the build.xml in the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.

The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.

Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:

<target depends="build-subprojects,build-project" name="build"/>

The build target does nothing itself. However, it depends upon two other targets, so these will be called first:

The first target is build-subprojects:

<target name="build-subprojects"/>

This does nothing at all. It doesn't even have a dependency.

The next target specified is build-project does have code:

<target depends="init" name="build-project">

This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:

<target name="init">
    <mkdir dir="bin"/>
    <copy includeemptydirs="false" todir="bin">
        <fileset dir="src">
            <exclude name="**/*.java"/>
        </fileset>
    </copy>
</target>

This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.

Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.

Next, we go back to our previous build-project target:

<target depends="init" name="build-project">
    <echo message="${ant.project.name}: ${ant.file}"/>
    <javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
        <src path="src"/>
        <classpath refid="iControlSilk4J.classpath"/>
    </javac>
</target>

Look at this line:

<echo message="${ant.project.name}: ${ant.file}"/>

That should have always executed. Did your output print:

[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

Maybe you didn't realize that was from your build.

After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.

And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:

C:\Silk4J\Automation\iControlSilk4J> ant -d clean build

However, Ant usually prints the target being executed. You should have seen this:

init:

build-subprojects:

build-projects:

    [echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

build:

Build Successful

Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.

• If the bin directory already exists, <mkdir/> isn't going to execute.
• If there are no non-Java files in src, or they have already been copied into bin, the <copy/> task won't execute.
• If there are no Java file in your src directory, or they have already been compiled, the <java/> task won't run.

If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.

See if that helps.

It will give you point of hook to put some code that you wish to be executed on web application deploy time

For Activities shown within TabActivities use getParent()

final AlertDialog.Builder builder = new AlertDialog.Builder(getParent());

instead of

final AlertDialog.Builder builder = new AlertDialog.Builder(this);

    $('#checkbox').click(function(){
        $('#submit').attr('disabled', !$(this).attr('checked'));
    });

If there are up to 10 strings then you should use a list in order to iterate through all values.

{% set list1 = variable1.split(';') %}
{% for list in list1 %}
<p>{{ list }}</p>
{% endfor %}

edit Outdated, just use git push -u origin $BRANCHNAME

Use git publish-branch from William's miscellaneous Git tools.

OK, no Ruby, so - ignoring the safeguards! - take the last three lines of the script and create a bash script, git-publish-branch:

#!/bin/bash
REMOTE=$1 # Rewrite this to make it optional...
BRANCH=$2
# Uncomment the following line to create BRANCH locally first
#git checkout -b ${BRANCH}
git push ${ORIGIN} ${BRANCH}:refs/heads/${BRANCH} &&
git config branch.${BRANCH}.remote ${REMOTE} &&
git config branch.${BRANCH}.merge refs/heads/${BRANCH}

Then run git-publish-branch REMOTENAME BRANCHNAME, where REMOTENAME is usually origin (you may modify the script to take origin as default, etc...)

If you want to get and set the property both, you can use this in C#7:

GetString(
    inputString,
    (() => client.WorkPhone, x => client.WorkPhone = x))

void GetString(string inValue, (Func<string> get, Action<string> set) outValue)
{
    if (!string.IsNullOrEmpty(outValue))
    {
        outValue.set(inValue);
    }
}

git fetch

git branch -r

git checkout <branch_name>

If you have more than one version of Python and the script needs to run under a specific version, the she-bang can ensure the right one is used when the script is executed directly, for example:

#!/usr/bin/python2.7

Note the script could still be run via a complete Python command line, or via import, in which case the she-bang is ignored. But for scripts run directly, this is a decent reason to use the she-bang.

#!/usr/bin/env python is generally the better approach, but this helps with special cases.

Usually it would be better to establish a Python virtual environment, in which case the generic #!/usr/bin/env python would identify the correct instance of Python for the virtualenv.

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.

In addition to display:block OR display:inline-block

Try giving sufficient padding to your .btn-pToolName and make sure you have the correct values for background-position

First of all if the size of the image is smaller than the container, then only "img-fluid" class will not solve your problem. you have to set the width of image to 100%, for that you can use Bootstrap class "w-100". keep in mind that "container-fluid" and "col-12" class sets left and right padding to 15px and "row" class sets left and right margin to "-15px" by default. make sure to set them to 0.

Note: "px-0" is a bootstrap class which sets left and right padding to 0 and
"mx-0" is a bootstrap class which sets left and right margin to 0

P.S. i am using Bootstrap 4.0 version.

 <div class="container-fluid px-0">
        <div class="row mx-0">
            <div class="col-12 px-0">
            <img src="images/top.jpg" class="img-fluid w-100">
            </div>
        </div>
    </div>

CSV can get complicated real fast.

Use something robust and well-tested:
FileHelpers: www.filehelpers.net

The FileHelpers are a free and easy to use .NET library to import/export data from fixed length or delimited records in files, strings or streams.

I was struggling and Found this Easy and Effective way from IntelliJ IDEA suggestion

<select id="country" formControlName="country"  >
  <option [defaultSelected]=true [value]="default" >{{default}}</option>
  <option *ngFor="let c of countries" [value]="c" >{{ c }}</option>
</select> 

And On your ts file assign the values

 countries = ['USA', 'UK', 'Canada'];
 default = 'UK'

Just make sure your formControlName accepts string, because you already assigned it as a string.

These solutions often have issues with the header columns aligning with the body columns, and may not work properly when resizing. I know you didn't want to use an additional library, but if you happen to be using jQuery, this one is really small. It supports fixed header, footer, column spanning (colspan), horizontal scrolling, resizing, and an optional number of rows to display before scrolling starts.

jQuery.scrollTableBody (GitHub)

As long as you have a table with proper <thead>, <tbody>, and (optional) <tfoot>, all you need to do is this:

$('table').scrollTableBody();

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>
#include <sys/socket.h>

    if (r) {                                                                                     \

    char msg[LEN];  // 1MB data
    memset(msg, 'a', LEN);

    for (int i = 0; i < 1000; ++i) {
        int len = send(fd, msg, LEN, 0);
        printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
        sleep(1);
    }

}

int main(){
    test_full_sock_buf_1();

    return 0;
}

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

connect to server successsend: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

After hours of trial and error, I've found a very easy way to put contents into scrollviews that are 'offscreen'. Tested with XCode 5 & iOS 7. You can do this almost entirely in Storyboard, using 2 small tricks/workarounds :

1. Drag a viewcontroller onto your storyboard.
2. Drag a scrollView on this viewController, for the demo you can leave its size default, covering the entire screen.
3. Now comes trick 1 : before adding any element to the scrollView, drag in a regular 'view' (This view will be made larger than the screen, and will contain all the sub elements like buttons, labels, ...let's call it the 'enclosing view').
4. Let this enclosing view's Y size in the size inspector to for example 800.
5. Drop in a label onto the enclosing view, somewhere at Y position 200, name it 'label 1'.
6. Trick 2 : make sure the enclosing view is selected (not the scrollView !), and set its Y position to for example -250, so you can add an item that is 'outside' the screen
7. Drop in a label, somewhere at the bottom of the screen, name it 'label 2'. This label is actually 'off screen'.
8. Reset the Y position of the enclosing view to 0, you'll no longer see label 2, as it was positioned off screen.

So far for the storyboard work, now you need to add a single line of code to the viewController's 'viewDidLoad' method to set the scrollViews contents so it contains the entire 'enclosing view'. I didn't find a way to do this in Storyboard:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.scrollView.contentSize = CGSizeMake(320, 800);
}

You can try doing this by adding a contentSize keyPath as a size to the scrollView in the Identity Inspector and setting it to (320, 1000).

I think Apple should make this easier in storyboard, in a TableViewController you can just scroll offscreen in Storyboard (just add 20 cells, and you'll see you can simply scroll), this should be possible with a ScrollViewController too.

Here is a regex for the following most common phone number scenarios. Although this is tailored from a US perspective for area codes it works for international scenarios.

1. The actual number should be 10 digits only.
2. For US numbers area code may be surrounded with parentheses ().
3. The country code can be 1 to 3 digits long. Optionally may be preceded by a + sign.
4. There may be dashes, spaces, dots or no spaces between country code, area code and the rest of the number.

5. A valid phone number cannot be all zeros.

   ^(?!\b(0)\1+\b)(\+?\d{1,3}[. -]?)?\(?\d{3}\)?([. -]?)\d{3}\3\d{4}$
   

Explanation:

    ^ - start of expression  
    (?!\b(0)\1+\b) - (?!)Negative Look ahead. \b - word boundary around a '0' character. \1 backtrack to previous capturing group (zero). Basically don't match all zeros.  
    (\+?\d{1,3}[. -]?)? - '\+?' plus sign before country code is optional.\d{1,3} - country code can be 1 to 3 digits long. '[. -]?' - spaces,dots and dashes are optional. The last question mark is to make country code optional.  
    \(?\d{3}\)? - '\)?' is to make parentheses optional. \d{3} - match 3 digit area code.  
    ([. -]?) - optional space, dash or dot
    $ - end of expression

myEditText.disableCopyAndPaste().

And it's works on the old API

on windows open a cmd.exe window with administrator permissions and use netstat -a -b -o you will get the id of the proccess that holds your port and be able to kill it using task manager.

dicts=[

print dicts_by_name['Tom']

#output

Also if you are looking for current file name along with the query string, you will just need following

basename($_SERVER['REQUEST_URI'])

It would provide you info like following example

file.php?arg1=val&arg2=val

And if you also want full path of file as well starting from root, e.g. /folder/folder2/file.php?arg1=val&arg2=val then just remove basename() function and just use fillowing

$_SERVER['REQUEST_URI']

//create a file handler by opening the file
$myTextFileHandler = @fopen("filelist.txt","r+");

//truncate the file to zero
//or you could have used the write method and written nothing to it
@ftruncate($myTextFileHandler, 0);

//use location header to go back to index.html
header("Location:index.html");

I don't exactly know where u want to show the result.

I figured out such data design:

Main sheet: Column A: Pump codes (numbers)

Column B: formula showing a corresponding row in sheet 'Ruhrpumpen'

=ROW(Pump_codes)+MATCH(A2;Ruhrpumpen!$I$5:$I$100;0)

Formulae have ";" instead of ",", it should be also German notation. If not, pleace replace.

Column C: formula showing data in 'Ruhrpumpen' column A from a row found by formula in col B

=INDIRECT("Ruhrpumpen!A"&$B2)

Column D: formula showing data in 'Ruhrpumpen' column B from a row found by formula in col B:

=INDIRECT("Ruhrpumpen!B"&$B2)

Sheet 'Ruhrpumpen':

Column A: some data about a certain pump

Column B: some more data

Column I: pump codes. Beginning of the list includes defined name 'Pump_codes' used by the formula in column B of the main sheet.

You can do it this way inside a program:

#include <sys/resource.h>

// core dumps may be disallowed by parent of this process; change that
struct rlimit core_limits;
core_limits.rlim_cur = core_limits.rlim_max = RLIM_INFINITY;
setrlimit(RLIMIT_CORE, &core_limits);

if (Arrays.asList(array).contains(string))

Old question, but since the question asks "using jQuery", I thought I'd provide an option that lets you do this without introducing any vendor dependency.

While there are a lot of templating engines out there, many of their features have fallen in to disfavour recently, with iteration (<% for), conditionals (<% if) and transforms (<%= myString | uppercase %>) seen as microlanguage at best, and anti-patterns at worst. Modern templating practices encourage simply mapping an object to its DOM (or other) representation, e.g. what we see with properties mapped to components in ReactJS (especially stateless components).

Templates Inside HTML

One property you can rely on for keeping the HTML for your template next to the rest of your HTML, is by using a non-executing <script> type, e.g. <script type="text/template">. For your case:

<script type="text/template" data-template="listitem">
    <a href="${url}" class="list-group-item">
        <table>
            <tr>
                <td><img src="${img}"></td>
                <td><p class="list-group-item-text">${title}</p></td>
            </tr>
        </table>
    </a>
</script>

On document load, read your template and tokenize it using a simple String#split

var itemTpl = $('script[data-template="listitem"]').text().split(/\$\{(.+?)\}/g);

Notice that with our token, you get it in the alternating [text, property, text, property] format. This lets us nicely map it using an Array#map, with a mapping function:

function render(props) {
  return function(tok, i) { return (i % 2) ? props[tok] : tok; };
}

Where props could look like { url: 'http://foo.com', img: '/images/bar.png', title: 'Lorem Ipsum' }.

Putting it all together assuming you've parsed and loaded your itemTpl as above, and you have an items array in-scope:

$('.search').keyup(function () {
  $('.list-items').append(items.map(function (item) {
    return itemTpl.map(render(item)).join('');
  }));
});

This approach is also only just barely jQuery - you should be able to take the same approach using vanilla javascript with document.querySelector and .innerHTML.

Templates inside JS

A question to ask yourself is: do you really want/need to define templates as HTML files? You can always componentize + re-use a template the same way you'd re-use most things you want to repeat: with a function.

In es7-land, using destructuring, template strings, and arrow-functions, you can write downright pretty looking component functions that can be easily loaded using the $.fn.html method above.

const Item = ({ url, img, title }) => `
  <a href="${url}" class="list-group-item">
    <div class="image">
      <img src="${img}" />
    </div>
    <p class="list-group-item-text">${title}</p>
  </a>
`;

Then you could easily render it, even mapped from an array, like so:

$('.list-items').html([
  { url: '/foo', img: 'foo.png', title: 'Foo item' },
  { url: '/bar', img: 'bar.png', title: 'Bar item' },
].map(Item).join(''));

Oh and final note: don't forget to sanitize your properties passed to a template, if they're read from a DB, or someone could pass in HTML (and then run scripts, etc.) from your page.

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

Look at the constructor for String

String str = new String(bytes, StandardCharsets.UTF_8);

And if you're feeling lazy, you can use the Apache Commons IO library to convert the InputStream to a String directly:

String str = IOUtils.toString(inputStream, StandardCharsets.UTF_8);

The problem seems to be that you are not returning something in the event that your first if-case is false.

The error you are getting states that your arrow function (comment) => { doesn't have a return statement. While it does for when your if-case is true, it does not return anything for when it's false.

return this.props.comments.map((comment) => {
  if (comment.hasComments === true) {
    return (
      <div key={comment.id}>
        <CommentItem className="MainComment" />
        {this.props.comments.map(commentReply => {
          if (commentReply.replyTo === comment.id) { 
            return (
              <CommentItem className="SubComment"/>
            )
          }
        })
        }
      </div>
    )
  } else {
     //return something here.
  }
});

edit you should take a look at Kris' answer for how to better implement what you are trying to do.

git diff branch_1..branch_2

That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:

git diff branch_1...branch_2

Make sure there are no 'echo off' statements in the scripts and call 'echo on' after calling each script to reset any you have missed.

The reason is that if echo is left on, then the command interpreter will output each command (after parameter processing) before executing it. Makes it look really bad for using in production, but very useful for debugging purposes as you can see where output has gone wrong.

Also, make sure you are checking the ErrorLevels set by the called batch scripts and programs. Remember that there are 2 different methods used in .bat files for this. If you called a program, the Error level is in %ERRORLEVEL%, while from batch files the error level is returned in the ErrorLevel variable and doesn't need %'s around it.

If you want to use the non-SSL source, try removing the HTTPS source first, and then adding the HTTP one:

sudo gem sources -r https://rubygems.org
sudo gem sources -a http://rubygems.org  

UPDATE:

As mpapis states, this should be used only as a temporary workaround. There could be some security concerns if you're accessing RubyGems through the non-SSL source.

Once the workaround is not needed anymore, you should restore the SSL-source:

sudo gem sources -r http://rubygems.org
sudo gem sources -a https://rubygems.org

The offending lines are the following:

MaxConnections=90
InitialConnections=80

You can increase the values to allow more connections.

Compare modifying value of variable versus modifying value of pointer:

#include <stdio.h>
#include <stdlib.h>

void changeA(int (*a))
{
  (*a) = 10;
}

void changeP(int *(*P))
{
  (*P) = malloc(sizeof((*P)));
}

int main(void)
{
  int A = 0;

  printf("orig. A = %d\n", A);
  changeA(&A);
  printf("modi. A = %d\n", A);

  /*************************/

  int *P = NULL;

  printf("orig. P = %p\n", P);
  changeP(&P);
  printf("modi. P = %p\n", P);

  free(P);

  return EXIT_SUCCESS;
}

This helped me to avoid returning value of pointer when the pointer was modified by the called function (used in singly linked list).

OLD (bad):

int *func(int *P)
{
  ...
  return P;
}

int main(void)
{
  int *pointer;
  pointer = func(pointer);
  ...
}    

NEW (better):

void func(int **pointer)
{
  ...
}

int main(void)
{
  int *pointer;
  func(&pointer);
  ...
}    

If you want to try it without the try catch block, can use the following method, Create a intent and set the package of the app which you want to verify

val intent = Intent(Intent.ACTION_VIEW)
intent.data = uri
intent.setPackage("com.example.packageofapp")

and the call the following method to check if the app is installed

fun isInstalled(intent:Intent) :Boolean{
    val list = context.packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
    return list.isNotEmpty()
}

The verification of the certificate identity is performed against what the client requests.

When your client uses https://xxx.xxx.xxx.xxx/something (where xxx.xxx.xxx.xxx is an IP address), the certificate identity is checked against this IP address (in theory, only using an IP SAN extension).

If your certificate has no IP SAN, but DNS SANs (or if no DNS SAN, a Common Name in the Subject DN), you can get this to work by making your client use a URL with that host name instead (or a host name for which the cert would be valid, if there are multiple possible values). For example, if you cert has a name for www.example.com, use https://www.example.com/something.

Of course, you'll need that host name to resolve to that IP address.

In addition, if there are any DNS SANs, the CN in the Subject DN will be ignored, so use a name that matches one of the DNS SANs in this case.

All the other answers have two main flaws:

1. They do a Python loop through the string, which is horrifically slow, or
2. They use numpy which is a pretty big additional dependency.

def findall(haystack, needle):
    idx = -1
    while True:
        idx = haystack.find(needle, idx+1)
        if idx == -1:
            break
        yield idx

This iterates through haystack looking for needle, always starting at where the previous iteration ended. It uses the builtin str.find which is much faster than iterating through haystack character-by-character. It doesn't require any new imports.

I was also lost around getMeasuredWidth() and getMeasuredHeight() getHeight() and getWidth() for a long time.......... later i found onSizeChanged() method to be REALLY helpful.

New Blog Post: how to get width and height dimensions of a customView (extends View) in Android http://syedrakibalhasan.blogspot.com/2011/02/how-to-get-width-and-height-dimensions.html

That's working for me in Kotlin.

1. Create the Adapter and hand over your data in the constructor

class LEDRecyclerAdapter (var currentPole: Pole): RecyclerView.Adapter<RecyclerView.ViewHolder>()  { ... }

2. change this property and call notifyDataSetChanged()

adapter.currentPole = pole
adapter.notifyDataSetChanged()

The scroll offset doesn't change.

I like a more general functional approach:

/**
* converts a trig function taking radians to degrees
* @param {function} trigFunc - eg. Math.cos, Math.sin, etc.
* @param {number} angle - in degrees
* @returns {number}
*/
const dTrig = (trigFunc, angle) => trigFunc(angle * Math.PI / 180);

or,

function dTrig(trigFunc, angle) {
  return trigFunc(angle * Math.PI / 180);
}

which can be used with any radian-taking function:

dTrig(Math.sin, 90);
  // -> 1

dTrig(Math.tan, 180);
  // -> 0

Hope this helps!

REST is light-weight in terms of encoding, much more useful for light weight devices i.e. non strict APIs.

REST is format independent. XML, HTML, JSON all options are available.

REST provides abilities for on 2 point message transfer (not surprising since REST stands for REpresentational State Transfer) where WSDL/SOAP interaction is multiple point message interaction.

REST does not require a new extension for XML messages, where in WSDL/SOAP this is the case.

WSDL/SOAP uses multiple transport protocols, REST relies on only HTTP. Therefore WSDL/SOAP can be used like a RESTful way, however simple requests can be overly complicated/heavy weighted.

A simple analogy: REST is like a motoboy delivers your food easy and quick. XML extended WSDL/SOAP more like UPS delivery, more structured and serious stuff but comes with a cost.

You can directly show image from web without downloading it. Please check the below function . It will show the images from the web into your image view.

public static Drawable LoadImageFromWebOperations(String url) {
    try {
        InputStream is = (InputStream) new URL(url).getContent();
        Drawable d = Drawable.createFromStream(is, "src name");
        return d;
    } catch (Exception e) {
        return null;
    }
}

then set image to imageview using code in your activity.

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

public static T DeserializeFromXml<T>(string xml)
{
    T result;
    XmlSerializerFactory serializerFactory = new XmlSerializerFactory();
    XmlSerializer serializer =serializerFactory.CreateSerializer(typeof(T));

    using (StringReader sr3 = new StringReader(xml))
    {
        XmlReaderSettings settings = new XmlReaderSettings()
        {
            CheckCharacters = false // default value is true;
        };

        using (XmlReader xr3 = XmlTextReader.Create(sr3, settings))
        {
            result = (T)serializer.Deserialize(xr3);
        }
    }

    return result;
}

dec2hex = function (d) {
  if (d > 15)
    { return d.toString(16) } else
    { return "0" + d.toString(16) }
}
rgb = function (r, g, b) { return "#" + dec2hex(r) + dec2hex(g) + dec2hex(b) };

and:

parent.childNodes[1].style.color = rgb(155, 102, 102);

Sounds like you're looking for the time_ago_in_words method (or distance_of_time_in_words), from ActiveSupport. Call it like this:

<%= time_ago_in_words(timestamp) %>

Because I am running python in a (pylons/pyramid) virtualenv, I could not run the binary installers (helpfully) linked to previously.

I had problems following the steps with Willie's answer, but I determined that the problem is (probably) that I am running windows 7 x64 install, which puts the registry key for mysql in a slightly different location, specifically in my case (note: I am running version 5.5) in: "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MySQL AB\MySQL Server 5.5".

HOWEVER, "HKEY_LOCAL_MACHINE\" cannot be included in the path or it will fail.

Also, I had to do a restart between steps 3 and 4.

After working through all of this, IMO it would have been smarter to run the entire python dev environment from cygwin.

Instead of doing all these, one can simply use ".Result" to get the result from a particular task.

eg: List list = GetListAsync().Result;

Which as per the definition => Gets the result value of this Task < TResult >

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

If you want the ApplicationUser object in one line of code (if you have the latest ASP.NET Identity installed), try:

ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

You'll need the following using statements:

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

Cmdlets in powershell accept a bunch of arguments. When these arguments are defined you can define a position for each of them.

This allows you to call a cmdlet without specifying the parameter name. So for the following cmdlet the path attribute is define with a position of 0 allowing you to skip typing -Path when invoking it and as such both the following will work.

Get-Item -Path C:\temp\thing.txt
Get-Item C:\temp\thing.txt

However if you specify more arguments than there are positional parameters defined then you will get the error.

Get-Item C:\temp\thing.txt "*"

As this cmdlet does not know how to accept the second positional parameter you get the error. You can fix this by telling it what the parameter is meant to be.

Get-Item C:\temp\thing.txt -Filter "*"

I assume you are getting the error on the following line of code as it seems to be the only place you are not specifying the parameter names correctly, and maybe it is treating the = as a parameter and $username as another parameter.

Set-ADUser $user -userPrincipalName = $newname

Try specifying the parameter name for $user and removing the =

keras predict_classes (docs) outputs A numpy array of class predictions. Which in your model case, the index of neuron of highest activation from your last(softmax) layer. [[0]] means that your model predicted that your test data is class 0. (usually you will be passing multiple image, and the result will look like [[0], [1], [1], [0]] )

You must convert your actual label (e.g. 'cancer', 'not cancer') into binary encoding (0 for 'cancer', 1 for 'not cancer') for binary classification. Then you will interpret your sequence output of [[0]] as having class label 'cancer'

I have seen this line of code

UIApplication.sharedApplication() .openURL(NSURL(string:"prefs:root=General")!)

is not working, it didn't work for me in ios10/ Xcode 8, just a small code difference, please replace this with

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=General")!)

Swift3

UIApplication.shared.openURL(URL(string:"prefs:root=General")!)

Replace with

UIApplication.shared.openURL(URL(string:"App-Prefs:root=General")!)

Hope it helps. Cheers.

function page_properties($objPortal) {

To get the key IDs (8 bytes, 16 hex digits), this is the command which worked for me in GPG 1.4.16, 2.1.18 and 2.2.19:

gpg --list-packets <key.asc | awk '$1=="keyid:"{print$2}'

To get some more information (in addition to the key ID):

gpg --list-packets <key.asc

To get even more information:

gpg --list-packets -vvv --debug 0x2 <key.asc

The command

gpg --dry-run --import <key.asc

also works in all 3 versions, but in GPG 1.4.16 it prints only a short (4 bytes, 8 hex digits) key ID, so it's less secure to identify keys.

Some commands in other answers (e.g. gpg --show-keys, gpg --with-fingerprint, gpg --import --import-options show-only) don't work in some of the 3 GPG versions above, thus they are not portable when targeting multiple versions of GPG.

Understand this has been solved, but the solution provided above might not work in all situation.

I was looking for an ExecutorService that can interrupt all timed out Runnables executed by it, but found none. After a few hours I created one as below. This class can be modified to enhance robustness.

public class TimedExecutorService extends ThreadPoolExecutor {
    long timeout;
    public TimedExecutorService(int numThreads, long timeout, TimeUnit unit) {
        super(numThreads, numThreads, 0L, TimeUnit.MILLISECONDS, new ArrayBlockingQueue<Runnable>(numThreads + 1));
        this.timeout = unit.toMillis(timeout);
    }

    @Override
    protected void beforeExecute(Thread thread, Runnable runnable) {
        Thread interruptionThread = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    // Wait until timeout and interrupt this thread
                    Thread.sleep(timeout);
                    System.out.println("The runnable times out.");
                    thread.interrupt();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        });
        interruptionThread.start();
    }
}

Usage:

public static void main(String[] args) {

    Runnable abcdRunnable = new Runnable() {
        @Override
        public void run() {
            System.out.println("abcdRunnable started");
            try {
                Thread.sleep(20000);
            } catch (InterruptedException e) {
                // logger.info("The runnable times out.");
            }
            System.out.println("abcdRunnable ended");
        }
    };

    Runnable xyzwRunnable = new Runnable() {
        @Override
        public void run() {
            System.out.println("xyzwRunnable started");
            try {
                Thread.sleep(20000);
            } catch (InterruptedException e) {
                // logger.info("The runnable times out.");
            }
            System.out.println("xyzwRunnable ended");
        }
    };

    int numThreads = 2, timeout = 5;
    ExecutorService timedExecutor = new TimedExecutorService(numThreads, timeout, TimeUnit.SECONDS);
    timedExecutor.execute(abcdRunnable);
    timedExecutor.execute(xyzwRunnable);
    timedExecutor.shutdown();
}

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

1. NSLog - add meta info (like timestamp and identifier) and allows you to output 1023 symbols. Also print message into Console. The slowest method

@import Foundation
NSLog("SomeString")

2. print - prints all string to Xcode. Has better performance than previous

@import Foundation
print("SomeString")

3. println (only available Swift v1) and add \n at the end of string
4. os_log (from iOS v10) - prints 32768 symbols also prints to console. Has better performance than previous

@import os.log
os_log("SomeIntro: %@", log: .default, type: .info, "someString")

5. Logger (from iOS v14) - prints 32768 symbols also prints to console. Has better performance than previous

@import os
let logger = Logger(subsystem: Bundle.main.bundleIdentifier!, category: "someCategory")
logger.log("\(s)")

Calling .attr("disabled", true) of course works, but using jQuery you'd like do it in more 'sugar' way, so I've written simple extension:

(function( $ ) {
  $.fn.disable = function(isDisabled) {
    var val = isDisabled;
    if (isDisabled === undefined)
        val = true;
    this.attr("disabled", val);
  };
  $.fn.enable = function(isEnabled) {
    var val = !isEnabled;
    if (isEnabled === undefined)
        val = false;
    this.attr("disabled", val); 
  }
})( jQuery );

Now you have functions enable() and disable(), so you can do your job that way:

$('#continueButton').disable();

Which is same as

$('#continueButton').disable(true);

and

$('#continueButton').enable(false);

Have you tried PyMedia? I am not 100% sure but it looks like this tutorial example targets your problem.

I'll assume you are not referring to literally the same objects

Object1 == Object2

You might be thinking about doing a memory comparison between the two

memcmp(Object1, Object2, sizeof(Object.GetType())

But that's not even real code in c# :). Because all of your data is probably created on the heap, the memory is not contiguous and you can't just compare the equality of two objects in an agnostic manner. You're going to have to compare each value, one at a time, in a custom way.

Consider adding the IEquatable<T> interface to your class, and define a custom Equals method for your type. Then, in that method, manual test each value. Add IEquatable<T> again on enclosed types if you can and repeat the process.

class Foo : IEquatable<Foo>
{
  public bool Equals(Foo other)
  {
    /* check all the values */
    return false;
  }
}

There's a couple of other tricks that Postgres offers for string matching (if that happens to be your DB):

ILIKE, which is a case insensitive LIKE match:

select * from people where name ilike 'JOHN'

Matches:

• John
• john
• JOHN

And if you want to get really mad you can use regular expressions:

select * from people where name ~ 'John.*'

Matches:

• John
• Johnathon
• Johnny

UPDATE: 30.07.2014

If you use Android Studio, make sure you have at least 144x144 resource and than use "FILE-NEW-IMAGE ASSET". Android Studio will make proper image files to all folders for you : )

As documentation says, adjust bitmaps as follows:

Almost every application should have alternative drawable resources for different screen densities, because almost every application has a launcher icon and that icon should look good on all screen densities. Likewise, if you include other bitmap drawables in your application (such as for menu icons or other graphics in your application), you should provide alternative versions or each one, for different densities.

Note: You only need to provide density-specific drawables for bitmap files (.png, .jpg, or .gif) and Nine-Path files (.9.png). If you use XML files to define shapes, colors, or other drawable resources, you should put one copy in the default drawable directory (drawable/).

To create alternative bitmap drawables for different densities, you should follow the 3:4:6:8 scaling ratio between the four generalized densities. For example, if you have a bitmap drawable that's 48x48 pixels for medium-density screen (the size for a launcher icon), all the different sizes should be:

36x36 for low-density (LDPI)

48x48 for medium-density (MDPI)

72x72 for high-density (HDPI)

96x96 for extra high-density (XHDPI)

144x144 for extra extra high-density (XXHDPI)

192x192 for extra extra extra high-density (XXXHDPI)

You could use an XPath, too. A bit old fashioned but still effective:

using System.Xml;

...

XmlDocument xmlDocument;

xmlDocument = new XmlDocument();
xmlDocument.LoadXml(xml);

foreach (XmlElement xmlElement in 
    xmlDocument.DocumentElement.SelectNodes("word[category='verb']"))
{
    Console.Out.WriteLine(xmlElement.OuterXml);
}

why do these two different operators, [ ], and [[ ]], return the same result?

x = list(1, 2, 3, 4)

1. [ ] provides sub setting operation. In general sub set of any object will have the same type as the original object. Therefore, x[1] provides a list. Similarly x[1:2] is a subset of original list, therefore it is a list. Ex.

   x[1:2]
   
   [[1]] [1] 1
   
   [[2]] [1] 2
   

2. [[ ]] is for extracting an element from the list. x[[1]] is valid and extract the first element from the list. x[[1:2]] is not valid as [[ ]] does not provide sub setting like [ ].

    x[[2]] [1] 2 
   
   > x[[2:3]] Error in x[[2:3]] : subscript out of bounds
   

For swift version

func getBoundsZoomLevel(bounds: GMSCoordinateBounds, mapDim: CGSize) -> Double {
        var bounds = bounds
        let WORLD_DIM = CGSize(width: 256, height: 256)
        let ZOOM_MAX: Double = 21.0
        func latRad(_ lat: Double) -> Double {
            let sin2 = sin(lat * .pi / 180)
            let radX2 = log10((1 + sin2) / (1 - sin2)) / 2
            return max(min(radX2, .pi), -.pi) / 2
        }
        func zoom(_ mapPx: CGFloat,_ worldPx: CGFloat,_ fraction: Double) -> Double {
            return floor(log10(Double(mapPx) / Double(worldPx) / fraction / log10(2.0)))
        }
        let ne = bounds.northEast
        let sw = bounds.southWest
        let latFraction = (latRad(ne.latitude) - latRad(sw.latitude)) / .pi
        let lngDiff = ne.longitude - sw.longitude
        let lngFraction = lngDiff < 0 ? (lngDiff + 360) : (lngDiff / 360)
        let latZoom = zoom(mapDim.height, WORLD_DIM.height, latFraction);
        let lngZoom = zoom(mapDim.width, WORLD_DIM.width, lngFraction);
        return min(latZoom, lngZoom, ZOOM_MAX)
    }

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

You don't need to do special things in the form. You just build the comment correctly in the show action:

class ArticlesController < ActionController::Base
  ....
  def show
    @article = Article.find(params[:id])
    @new_comment = @article.comments.build
  end
  ....
end

and then make a form for it in the article view:

<% form_for @new_comment do |f| %>
   <%= f.text_area :text %>
   <%= f.submit "Post Comment" %>
<% end %>

by default, this comment will go to the create action of CommentsController, which you will then probably want to put redirect :back into so you're routed back to the Article page.

Sort, then reverse.

Your arguments are in the wrong order. The connection comes first according to the docs

<?php
require("constants.php");

// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);

if (!$connection) {
    error_log("Failed to connect to MySQL: " . mysqli_error($connection));
    die('Internal server error');
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    error_log("Database selection failed: " . mysqli_error($connection));
    die('Internal server error');
}

?>

• First,in your celery APP:

vi my_celery_apps/app1.py

app = Celery(worker_name)

• and next, change to the task file,import app from your celery app module.

vi tasks/task1.py

from my_celery_apps.app1 import app

app.AsyncResult(taskid)

try:
   if task.state.lower() != "success":
        return
except:

You can expend the following function in order to pull out more parameters from the DB before the insert:

--
-- insert_employee  (Function) 
--
CREATE OR REPLACE FUNCTION insert_employee(p_emp_id in number, p_emp_name in varchar2, p_emp_address in varchar2, p_emp_state in varchar2, p_emp_position in varchar2, p_emp_manager in varchar2) 
RETURN VARCHAR2 AS

   p_state_id varchar2(30) := '';
 BEGIN    
      select state_id 
      into   p_state_id
      from states where lower(emp_state) = state_name;

      INSERT INTO Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager) VALUES 
                (p_emp_id, p_emp_name, p_emp_address, p_state_id, p_emp_position, p_emp_manager);

    return 'SUCCESS';

I am using JPA (OpenJPA implementation from Apache which is based on the KODO JDO codebase which is 5+ years old and extremely fast/reliable). IMHO anyone who tells you to bypass the specs is giving you bad advice. I put the time in and was definitely rewarded. With either JDO or JPA you can change vendors with minimal changes (JPA has orm mapping so we are talking less than a day to possibly change vendors). If you have 100+ tables like I do this is huge. Plus you get built0in caching with cluster-wise cache evictions and its all good. SQL/Jdbc is fine for high performance queries but transparent persistence is far superior for writing your algorithms and data input routines. I only have about 16 SQL queries in my whole system (50k+ lines of code).

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

A performance-driven approach - calling environ is expensive, so it's better to call it once and save it to a dictionary. Full example:

from os import environ


# Slower
print(environ["USER"], environ["NAME"])

# Faster
env_dict = dict(environ)
print(env_dict["USER"], env_dict["NAME"])

P.S- if you worry about exposing private environment variables, then sanitize env_dict after the assignment.

An aggregate function requires a GROUP BY in standard SQL

This is "Get minimum date per title" in plain language

SELECT title, MIN(date) FROM table GROUP BY title

Most RDBMS and the standard require that column is either in the GROUP BY or in a functions (MIN, COUNT etc): MySQL is the notable exception with some extensions that give unpredictable behaviour

Names = []
for line in open('names.txt','r').readlines():
    Names.append(line.strip())

strip() cut spaces in before and after string...

Instead of using log4net which is an external library I have created my own simple class, highly customizable and easy to use (edit YOURNAMESPACEHERE with the namespace that you need).

CONSOLE APP

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,
        Warning = 2,
        Error = 3
    }

    internal static class Log
    {
        private static readonly string LogSession = DateTime.Now.ToLocalTime().ToString("ddMMyyyy_HHmmss");
        private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

        internal static void Write(LogEvent Level, string Message, bool ShowConsole = true, bool WritelogFile = true)
        {
            string Event = string.Empty;
            ConsoleColor ColorEvent = Console.ForegroundColor;

            switch (Level)
            {
                case LogEvent.Info:
                    Event = "INFO";
                    ColorEvent = ConsoleColor.White;
                    break;
                case LogEvent.Success:
                    Event = "SUCCESS";
                    ColorEvent = ConsoleColor.Green;
                    break;
                case LogEvent.Warning:
                    Event = "WARNING";
                    ColorEvent = ConsoleColor.Yellow;
                    break;
                case LogEvent.Error:
                    Event = "ERROR";
                    ColorEvent = ConsoleColor.Red;
                    break;
            }

            if (ShowConsole)
            {
                Console.ForegroundColor = ColorEvent;
                Console.WriteLine(" [{0}] => {1}", DateTime.Now.ToString("HH:mm:ss"), Message);
                Console.ResetColor();
            }

            if (WritelogFile)
            {
                if (!Directory.Exists(LogPath))
                    Directory.CreateDirectory(LogPath);

                File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
            }
        }
    }
}

NO CONSOLE APP (ONLY LOG)

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,
        Warning = 2,
        Error = 3
    }

internal static class Log
{
    private static readonly string LogSession = DateTime.Now.ToLocalTime().ToString("ddMMyyyy_HHmmss");
    private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

    internal static void Write(LogEvent Level, string Message)
    {
        string Event = string.Empty;

        switch (Level)
        {
            case LogEvent.Info:
                Event = "INFO";
                break;
            case LogEvent.Success:
                Event = "SUCCESS";
                break;
            case LogEvent.Warning:
                Event = "WARNING";
                break;
            case LogEvent.Error:
                Event = "ERROR";
                break;
        }

        if (!Directory.Exists(LogPath))
            Directory.CreateDirectory(LogPath);

        File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
    }
}

Usage:

CONSOLE APP

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your console, also will save a copy of this print in a .log file.
Log.Write(LogEvent.Warning, "Test message", false); // It will save the print as warning only in your .log file.
Log.Write(LogEvent.Error, "Test message", true, false); // It will print an error only in your console.

NO CONSOLE APP (ONLY LOG)

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your .log file.

Fred Haslam's way works fine. I had trouble with the filepath though, since I want to reference an image within my jar. To do this, I used:

BufferedImage wPic = ImageIO.read(this.getClass().getResource("snow.png"));
JLabel wIcon = new JLabel(new ImageIcon(wPic));

Since I only have a finite number (about 10) images that I need to load using this method, it works quite well. It gets file without having to have the correct relative filepath.

Strings are immutable in Python. The replace method returns a new string after the replacement. Try:

for char in line:
    if char in " ?.!/;:":
        line = line.replace(char,'')

This is identical to your original code, with the addition of an assignment to line inside the loop.

Note that the string replace() method replaces all of the occurrences of the character in the string, so you can do better by using replace() for each character you want to remove, instead of looping over each character in your string.

I had this problem, but fixed it by referencing the DLL from "C:\Program Files\Reference Assemblies\Microsoft\Windows Identity Foundation\v3.5\Microsoft.IdentityModel.dll"

Go to reference properties and set Copy Local to True for the DLL. The DLL will now be included in the azure package.

If you're not worried about a couple minutes time to do so, a solution would be to rm -rf node_modules and npm install again to rebuild the local modules.

If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.

Go to Search → Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:

• Find What = (cat|town)

• Filters = *.txt

• Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

• Search mode = Regular Expression

SshClient cSSH = new SshClient("192.168.10.144", 22, "root", "pacaritambo");
cSSH.Connect();
SshCommand x = cSSH.RunCommand("exec \"/var/lib/asterisk/bin/retrieve_conf\"");
cSSH.Disconnect();
cSSH.Dispose();

//using SSH.Net

instead of using " + " operator

print( "Alireza" + 1980)

Use comma " , " operator

print( "Alireza" , 1980)

Sorry I haven.t read all replies to your question.

Yeah here the thing you want (I have done already)

You can use two tables, with same class name for similar styling, one only with table head and another with your rows. Now put this table inside a div having fixed height with overflow-y:auto OR scroll.

Multiple choice version:

ask () {                        # $1=question $2=options
    # set REPLY
    # options: x=..|y=..
    while $(true); do
        printf '%s [%s] ' "$1" "$2"
        stty cbreak
        REPLY=$(dd if=/dev/tty bs=1 count=1 2> /dev/null)
        stty -cbreak
        test "$REPLY" != "$(printf '\n')" && printf '\n'
        (
            IFS='|'
            for o in $2; do
                if [ "$REPLY" = "${o%%=*}" ]; then
                    printf '\n'
                    break
                fi
            done
        ) | grep ^ > /dev/null && return
    done
}

Example:

$ ask 'continue?' 'y=yes|n=no|m=maybe'
continue? [y=yes|n=no|m=maybe] g
continue? [y=yes|n=no|m=maybe] k
continue? [y=yes|n=no|m=maybe] y
$

It will set REPLY to y (inside the script).

Update for iOS 7

Apple docs for UIActionSheet: UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy

I recommend against trying to customize the contents of an ActionSheet, as it can lead to serious invalid context errors in iOS 7. I just spent a few hours working through this problem and ultimately decided to take a different approach. I replaced the call to show the action sheet with a modal view controller containing a simple tableview.

There are many ways to accomplish this. Here's one way that I just implemented in a current project. It's nice because I can reuse it between 5 or 6 different screens where I all users to select from a list of options.

1. Create a new UITableViewController subclass, SimpleTableViewController.
2. Create a UITableViewController in your storyboard (embedded in a navigation controller) and set its custom class to SimpleTableViewController.
3. Give the navigation controller for SimpleTableViewController a Storyboard ID of "SimpleTableVC".
4. In SimpleTableViewController.h, create an NSArray property that will represent the data in the table.
5. Also in SimpleTableViewController.h, create a protocol SimpleTableViewControllerDelegate with a required method itemSelectedatRow:, and a weak property called delegate of type id<SimpleTableViewControllerDelegate>. This is how we will pass the selection back to the parent controller.
6. In SimpleTableViewController.m, implement the tableview data source and delegate methods, calling itemSelectedatRow: in tableView:didSelectRowAtIndexPath:.

This approach has the added benefit of being fairly reusable. To use, import the SimpleTableViewController class in your ViewController.h, conform to the SimpleTableViewDelegate, and implement the itemSelectedAtRow: method. Then, to open the modal just instantiate a new SimpleTableViewController, set the table data and delegate, and present it.

UINavigationController *navigationController = (UINavigationController *)[self.storyboard instantiateViewControllerWithIdentifier:@"SimpleTableVC"];
SimpleTableViewController *tableViewController = (SimpleTableViewController *)[[navigationController viewControllers] objectAtIndex:0];
tableViewController.tableData = self.statesArray;
tableViewController.navigationItem.title = @"States";
tableViewController.delegate = self;
[self presentViewController:navigationController animated:YES completion:nil];

I create a simple example and posted it on github.

Also see Showing actionsheet causes CGContext invalid context errors.

To add yet another potential solution, Helium by Clockworkmod has it's own version of ADB built in that kept being started. Exiting the Helium Desktop application resolves the issue.

By far the best option nowadays would be using a maven container as a builder tool. A mvn.sh script like this would be enough:

#!/bin/bash
docker run --rm -ti \
 -v $(pwd):/opt/app \
 -w /opt/app \
 -e TERM=xterm \
 -v $HOME/.m2:/root/.m2 \
 maven mvn "$@"

after struggling with this for a couple of hours, I've found that you can only use one db helper object per db execution. For example,

for(int x = 0; x < someMaxValue; x++)
{
    db = new DBAdapter(this);
    try
    {

        db.addRow
        (
                NamesStringArray[i].toString(), 
                StartTimeStringArray[i].toString(),
                EndTimeStringArray[i].toString()
        );

    }
    catch (Exception e)
    {
        Log.e("Add Error", e.toString());
        e.printStackTrace();
    }
    db.close();
}

as apposed to:

db = new DBAdapter(this);
for(int x = 0; x < someMaxValue; x++)
{

    try
    {
        // ask the database manager to add a row given the two strings
        db.addRow
        (
                NamesStringArray[i].toString(), 
                StartTimeStringArray[i].toString(),
                EndTimeStringArray[i].toString()
        );

    }
    catch (Exception e)
    {
        Log.e("Add Error", e.toString());
        e.printStackTrace();
    }

}
db.close();

creating a new DBAdapter each time the loop iterates was the only way I could get my strings into a database through my helper class.

Found in: Parent components gets empty Params from ActivatedRoute

Worked for me:

import {Component, OnDestroy, OnInit} from '@angular/core';
import { Router, ActivatedRoute, Params, RoutesRecognized } from '@angular/router';

@Component({
  selector: 'app-navigation-bar',
  templateUrl: './navigation-bar.component.html',
  styleUrls: ['./navigation-bar.component.scss']
})
export class NavigationBarComponent implements OnInit, OnDestroy {
  private sub: any;
  constructor(private route: ActivatedRoute, private router: Router) {}

  ngOnInit() {
    this.sub = this.router.events.subscribe(val => {
      if (val instanceof RoutesRecognized) {
        console.log(val.state.root.firstChild.params);
      }
    });
  }

  ngOnDestroy() {
    this.sub.unsubscribe();
  }

}

You can both remove row names and convert them to a column by reference (without reallocating memory using ->) using setDT and its keep.rownames = TRUE argument from the data.table package

library(data.table)

As mentioned by @snoram, you can give the new column any name you want, e.g. setDT(df, keep.rownames = "newname") would add "newname" as the rows column.

A modern approach is to use ASP.NET Web API 2 (server-side) with jQuery Ajax (client-side).

Like page methods and ASMX web methods, Web API allows you to write C# code in ASP.NET which can be called from a browser or from anywhere, really!

Here is an example Web API controller, which exposes API methods allowing clients to retrieve details about 1 or all products (in the real world, products would likely be loaded from a database):

public class ProductsController : ApiController
{
    Product[] products = new Product[] 
    { 
        new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 }, 
        new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M }, 
        new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M } 
    };

    [Route("api/products")]
    [HttpGet]
    public IEnumerable<Product> GetAllProducts()
    {
        return products;
    }

    [Route("api/product/{id}")]
    [HttpGet]
    public IHttpActionResult GetProduct(int id)
    {
        var product = products.FirstOrDefault((p) => p.Id == id);
        if (product == null)
        {
            return NotFound();
        }
        return Ok(product);
    }
}

The controller uses this example model class:

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public decimal Price { get; set; }
}

Example jQuery Ajax call to get and iterate over a list of products:

$(document).ready(function () {
    // Send an AJAX request
    $.getJSON("/api/products")
        .done(function (data) {
            // On success, 'data' contains a list of products.
            $.each(data, function (key, item) {
                // Add a list item for the product.
                $('<li>', { text: formatItem(item) }).appendTo($('#products'));
            });
        });
});

Not only does this allow you to easily create a modern Web API, you can if you need to get really professional and document it too, using ASP.NET Web API Help Pages and/or Swashbuckle.

Web API can be retro-fitted (added) to an existing ASP.NET Web Forms project. In that case you will need to add routing instructions into the Application_Start method in the file Global.asax:

RouteTable.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = System.Web.Http.RouteParameter.Optional }
);

I don't actually get an error with this.

a <- as.data.frame(matrix(c(sample(letters,50, replace=T),runif(100)), nrow=50))
b <- sample(letters,10, replace=T)
c <- cbind(a,b)

I used letters incase joining all numerics had different functionality (which it didn't). Your 'first data frame', which is actually just a vector', is just repeated 5 times in that 4th column...

But all the comments from the gurus to the question are still relevant :)

Use this for functions when you wish to simply alter the original variable and return it again to the same variable name with its new value assigned.

function add(&$var){ // The & is before the argument $var
   $var++;
}
$a = 1;
$b = 10;
add($a);
echo "a is $a,";
add($b);
echo " a is $a, and b is $b"; // Note: $a and $b are NOT referenced

Visible gallery changes visibility which is how you get the gallery over other view overlap. the Home sample app has some good examples of this technique.

Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.

DECLARE @CountResults TABLE (CountReturned INT)
DECLARE 
    @SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
    , @Count INT

INSERT @CountResults
EXEC(@SqlStatement)

SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count

If you really don't want to run into lots of annoying errors (datediff and such can't be evaluated in DataTable.Select among other things and even if you do as suggested use DataTable.AsEnumerable you will have trouble evaluating DateTime fields) do the following:

1) Model Your Data (create a class with DataTable columns)

Example

public class Person
{
public string PersonId { get; set; }
public DateTime DateBorn { get; set; }
}

2) Add this helper class to your code

public static class Extensions
{
/// <summary>
/// Converts datatable to list<T> dynamically
/// </summary>
/// <typeparam name="T">Class name</typeparam>
/// <param name="dataTable">data table to convert</param>
/// <returns>List<T></returns>
public static List<T> ToList<T>(this DataTable dataTable) where T : new()
{
    var dataList = new List<T>();

    //Define what attributes to be read from the class
    const BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;

    //Read Attribute Names and Types
    var objFieldNames = typeof(T).GetProperties(flags).Cast<PropertyInfo>().
        Select(item => new
        {
            Name = item.Name,
            Type = Nullable.GetUnderlyingType(item.PropertyType) ?? item.PropertyType
        }).ToList();

    //Read Datatable column names and types
    var dtlFieldNames = dataTable.Columns.Cast<DataColumn>().
        Select(item => new {
            Name = item.ColumnName,
            Type = item.DataType
        }).ToList();

    foreach (DataRow dataRow in dataTable.AsEnumerable().ToList())

3) Easily convert your DataTable (dt) to a List of objects with following code:

List<Person> persons = Extensions.ToList<Person>(dt);

4) have fun using Linq without the annoying row.Field<type> bit you have to use when using AsEnumerable

Example

var personsBornOn1980 = persons.Where(x=>x.DateBorn.Year == 1980);

You need

String guid = System.Guid.NewGuid().ToString();

If you meant disable all the inputs in an Angular form at once:

1- Reactive Forms:

myFormGroup.disable() // where myFormGroup is a FormGroup 

2- Template driven forms (NgForm):

You should get hold of the NgForm in a NgForm variable (for ex. named myNgForm) then

myNgForm.form.disable() // where form here is an attribute of NgForm 
                      // & of type FormGroup so it accepts the disable() function

In case of NgForm , take care to call the disable method in the right time

To determine when to call it, You can find more details in this Stackoverflow answer

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

The optimizer should eliminate most of the local variables. The tmp pointer is there to make sure strcpy doesn't have to walk the string to find the null. tmp points to the end of result after each call. (See Shlemiel the painter's algorithm for why strcpy can be annoying.)

// You must free the result if result is non-NULL.
char *str_replace(char *orig, char *rep, char *with) {
    char *result; // the return string
    char *ins;    // the next insert point
    char *tmp;    // varies
    int len_rep;  // length of rep (the string to remove)
    int len_with; // length of with (the string to replace rep with)
    int len_front; // distance between rep and end of last rep
    int count;    // number of replacements

    // sanity checks and initialization
    if (!orig || !rep)
        return NULL;
    len_rep = strlen(rep);
    if (len_rep == 0)
        return NULL; // empty rep causes infinite loop during count
    if (!with)
        with = "";
    len_with = strlen(with);

    // count the number of replacements needed
    ins = orig;
    for (count = 0; tmp = strstr(ins, rep); ++count) {
        ins = tmp + len_rep;
    }

    tmp = result = malloc(strlen(orig) + (len_with - len_rep) * count + 1);

    if (!result)
        return NULL;

    // first time through the loop, all the variable are set correctly
    // from here on,
    //    tmp points to the end of the result string
    //    ins points to the next occurrence of rep in orig
    //    orig points to the remainder of orig after "end of rep"
    while (count--) {
        ins = strstr(orig, rep);
        len_front = ins - orig;
        tmp = strncpy(tmp, orig, len_front) + len_front;
        tmp = strcpy(tmp, with) + len_with;
        orig += len_front + len_rep; // move to next "end of rep"
    }
    strcpy(tmp, orig);
    return result;
}

This code will always fail.

As written, it says: "Look for a property named "Employee" on my DataContext property, and set it to the DataContext property". Clearly that isn't right.

To get your code to work, as is, change your window declaration to:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:SampleApplication"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
   <local:Employee/>
</Window.DataContext>

This declares a new XAML namespace (local) and sets the DataContext to an instance of the Employee class. This will cause your bindings to display the default data (from your constructor).

However, it is highly unlikely this is actually what you want. Instead, you should have a new class (call it MainViewModel) with an Employee property that you then bind to, like this:

public class MainViewModel
{
   public Employee MyEmployee { get; set; } //In reality this should utilize INotifyPropertyChanged!
}

Now your XAML becomes:

<Window x:Class="SampleApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SampleApplication"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
       <local:MainViewModel/>
    </Window.DataContext>
    ...
    <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding MyEmployee.EmpID}" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding MyEmployee.EmpName}" />

Now you can add other properties (of other types, names), etc. For more information, see Implementing the Model-View-ViewModel Pattern

In trying to support both iOS8 and lower, I didn't have much luck using isRegisteredForRemoteNotifications as Kevin suggested. Instead I used currentUserNotificationSettings, which worked great in my testing.

+ (BOOL)notificationServicesEnabled {
    BOOL isEnabled = NO;

    if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]){
        UIUserNotificationSettings *notificationSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];

        if (!notificationSettings || (notificationSettings.types == UIUserNotificationTypeNone)) {
            isEnabled = NO;
        } else {
            isEnabled = YES;
        }
    } else {
        UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        if (types & UIRemoteNotificationTypeAlert) {
            isEnabled = YES;
        } else{
            isEnabled = NO;
        }
    }

    return isEnabled;
}

Try to temporarily modify request.js and harcode everywhere rejectUnauthorized = true, but it would be better to get the certificate extended as a long-term solution.

Hi according to our test between 2 different servers the results are as follows:

using curl for checking 10 .png files (each about 5 mb) was on average 5.7 secs. using header check for the same thing took average of 7.8 seconds!

So in our test curl was much faster if you have to check larger files!

our curl function is:

function remote_file_exists($url){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_NOBODY, true);
    curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    if( $httpCode == 200 ){return true;}
    return false;
}

here is our header check sample:

function UR_exists($url){
   $headers=get_headers($url);
   return stripos($headers[0],"200 OK")?true:false;
}

S.Lott inserted a comment, but it should be an answer: see the same question.

EDIT

Since it wasn't as obvious as I intended it to be, here follows a verbatim copy of S.Lott's answer in the other question:

I'm a big fan of ARGO UML from Tigris.org. Draws nice pictures using standard UML notation. It does some code generation, but mostly Java classes, which isn't SQL DDL, so that may not be close enough to what you want to do.

You can look at the Data Modelling Tools list and see if anything there is better than Argo UML. Many of the items on this list are free or cheap.

Also, if you're using Eclipse or NetBeans, there are many design plug-ins, some of which may have the features you're looking for.

This is my simple solution

var arr = ["you", "are", "the", "love", "of", "my", "life"];
var sorted = arr.sort(function (a, b){
     return b.length - a.length;
});

console.log(sorted[0])

I know this is an old question and I probably won't help, but many Linux distributions(e.g., ubuntu) have a "Live cd/usb" function, so if you really need to run this script, you could try booting your computer into Linux. Just burn a .iso to a flash drive (here's how http://goo.gl/U1wLYA), start your computer with the drive plugged in, and press the F key for boot menu. If you choose "...USB...", you will boot into the OS you just put on the drive.

Set the parent div to position: relative, then the inner div to...

position: absolute; 
bottom: 0;

...and there you go :)

sc queryex type= service state= all | find /i "NATION"

• use /i for case insensitive search
• the white space after type=is deliberate and required

Assuming you are on Linux, check if php-fpm is running by searching through the process list:

ps aux | grep php-fpm

If running over IP (as opposed to over Unix socket) then you can also check for the port:

netstat -an | grep :9000

Or using nmap:

nmap localhost -p 9000

Lastly, I've read that you can request the status, but in my experience this has proven unreliable:

/etc/init.d/php5-fpm status

Assuming you mean it's a string, how about strtol?

As stated in a similar question, try removing instances of the input-group class and see if that helps.

refering to bootstrap:

Individual form controls automatically receive some global styling. All textual , , and elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

I just discovered csvkit, which is a set of Unix command-line tools for CSV files. I installed it on my Mac with pip install csvkit. The command was:

csvsql --dialect mysql --snifflimit 100000 bigdatafile.csv > maketable.sql

You can alternatively provide a DB connection string and it can load the table directly.

I Have faced the same issue.After a lot of struggle I found that the real issue is with the com.amazonaws dependencies.After adding dependencies this error got disappeared.

It provides possibility to verify selectors and also to generate/modify selectors by clicking on element attributes.

Cities of the world database donated by MaxMind.com

The company MaxMind.com1 has agreed to release their cities of the world database under the GPL. The database contains locations by country, city, latitude and longitude. There are over 3,047,000 records in the database. For those of you who have tried the location.module with the zipcodes database from CivicSpace, you will recognize how cool it is and how well this fits with that project and therefore Drupal.

Here's another free one that might help you get started.

Creating and maintaining such a database is quite a bit of work - so anyone who's done it is likely keeping it to themselves, or offering it for a fee.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

Click in the logcat window (on a log even). Followed by "Ctrl + A" (select all). Then either "Right click with the mouse" or "Ctrl +C" (copy). Then paste it anywhere you like using any editor you like. One could also delete the logcat output before the logs relevant to us appear (before we start testing our use case) to get only relevant logs in the logcat.

In Python 3, raw_input() was renamed to input().

input([prompt])

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So you can do this way

x, y = input('Enter two numbers separating by a space: ').split();
print(int(x) + int(y))

If you do not put two numbers using a space you would get a ValueError exception. So that is good to go.

N.B. If you need old behavior of input(), use eval(input())

The solution was simply to comment the lines "work_mem=256MB" and "maintenance_work_mem=$3GB" in the file postgresql.conf and try to start the postgresql service. (start -> run -> services.msc) and look for the postgresql-[version] service then right click and start.

First of all, I would not make any changes directly in the "main" repo. If you really want to have a "main" repo, then you should only push to it, never change it directly.

Regarding the error you are getting, have you tried git pull from your local repo, and then git push to the main repo? What you are currently doing (if I understood it well) is forcing the push and then losing your changes in the "main" repo. You should merge the changes locally first.

I had this issue after upgrading to the Eclipse 2019-12 release. Somehow the command line to launch the JVM got too long and I had to enable the jar-classpath option in the run configuration (right click on file -> run as -> run configs).

Use the -v flag:

$ gem install fog -v 1.8

So add primary key to the auto_increment field:

CREATE TABLE book (
   id INT AUTO_INCREMENT primary key NOT NULL,
   accepted_terms BIT(1) NOT NULL,
   accepted_privacy BIT(1) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

C# Example Below:

string scheme = "http://";
string rootUrl = default(string);
if (Request.ServerVariables["HTTPS"].ToString().ToLower() == "on")
{
  scheme = "https://";
}
rootUrl = scheme + Request.ServerVariables["SERVER_NAME"].ToString();

See this reference for information on how to bind/unbind your solution or project from source control. NOTE: this doesn't apply if you are using GIT and may not apply to versions later than VS2008.

Quoting from the reference:

To disconnect a solution or project from source control

1. In Visual Studio, open Solution Explorer and select the item(s) to disconnect.

2. On the File menu, click Source Control, then Change Source Control.

3. In the Change Source Control dialog box, click Disconnect.

4. Click OK.

The enum (abbreviation of enumeration) is used to enumerate a set of values (enumerators). A value is an abstract thing represented by a symbol (a word). For example, a basic enum could be

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl };

This enum is called anonymous because you do not have a symbol to name it. But it is still perfectly correct. Just use it like this

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize;

Ok. The life is beautiful and everything goes well. But one day you need to reuse this enum to define a new variable to store myGrandFatherPantSize, then you write:

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize;
enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandFatherPantSize;

But then you have a compiler error "redefinition of enumerator". Actually, the problem is that the compiler is not sure that you first enum and you are second describe the same thing.

Then if you want to reuse the same set of enumerators (here xs...xxxxl) in several places you must tag it with a unique name. The second time you use this set you just have to use the tag. But don't forget that this tag does not replace the enum word but just the set of enumerators. Then take care to use enum as usual. Like this:

// Here the first use of my enum
enum sizes { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize; 
// here the second use of my enum. It works now!
enum sizes myGrandFatherPantSize;

you can use it in a parameter definition as well:

// Observe that here, I still use the enum
- (void) buyANewDressToMyGrandMother:(enum sizes)theSize;

You could say that rewriting enum everywhere is not convenient and makes the code looks a bit strange. You are right. A real type would be better.

This is the final step of our great progression to the summit. By just adding a typedef let's transform our enum in a real type. Oh the last thing, typedef is not allowed within your class. Then define your type just above. Do it like this:

// enum definition
enum sizes { xs,s,m,l,xl,xxl,xxxl,xxxxl };
typedef enum sizes size_type

@interface myClass {
   ...
   size_type myGrandMotherDressSize, myGrandFatherPantSize;
   ...
}

Remember that the tag is optional. Then since here, in that case, we do not tag the enumerators but just to define a new type. Then we don't really need it anymore.

// enum definition
typedef enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } size_type;

@interface myClass : NSObject {
  ...
  size_type myGrandMotherDressSize, myGrandFatherPantSize;
  ...
}
@end

If you are developing in Objective-C with XCode I let you discover some nice macros prefixed with NS_ENUM. That should help you to define good enums easily and moreover will help the static analyzer to do some interesting checks for you before to compile.

Good Enum!

The browser only allows numerical inputs when the type is set to "number". Details here.

You can use the type="text" and filter out any other than numerical input using JavaScript like descripted here

There are two different methods for iPad and iPhone platforms, so you need to implement both:

• selection handler and

• segue.

  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
  [self.tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
  
  // Selection handler (for horizontal iPad)
  [self tableView:self.tableView didSelectRowAtIndexPath:indexPath];
  
  // Segue (for iPhone and vertical iPad)
  [self performSegueWithIdentifier:"showDetail" sender:self];
  

The error here, is since calling the DataFrame constructor with scalar values (where it expects values to be a list/dict/... i.e. have multiple columns):

pd.DataFrame(d)
ValueError: If using all scalar values, you must must pass an index

You could take the items from the dictionary (i.e. the key-value pairs):

In [11]: pd.DataFrame(d.items())  # or list(d.items()) in python 3
Out[11]:
             0    1
0   2012-07-02  392
1   2012-07-06  392
2   2012-06-29  391
3   2012-06-28  391
...

In [12]: pd.DataFrame(d.items(), columns=['Date', 'DateValue'])
Out[12]:
          Date  DateValue
0   2012-07-02        392
1   2012-07-06        392
2   2012-06-29        391

But I think it makes more sense to pass the Series constructor:

In [21]: s = pd.Series(d, name='DateValue')
Out[21]:
2012-06-08    388
2012-06-09    388
2012-06-10    388

In [22]: s.index.name = 'Date'

In [23]: s.reset_index()
Out[23]:
          Date  DateValue
0   2012-06-08        388
1   2012-06-09        388
2   2012-06-10        388

Suppose you have some thing like this:

<div class="content">
    ... // inner HTML
</div>

and you want add a background to it, but you do not know the dimension of the image.

I had a similar problem, and I solved it by using grid:

HTML

<div class="outer">
    <div class="content">
        ... // inner HTML
    </div>
    <img class="background" />
</div>

CSS

.outer{
    display: grid;
    grid-template: auto / auto;
    // or you can assign a name for this block
}
.content{
    grid-area: 1 / 1 / 2 / 2;
    z-index: 2;
}
.background{
    grid-area: 1 / 1 / 2 / 2;
    z-index: 1;
}

z-index is just for placing image actually at the background, you can of course place img.background above the div.content.

NOTE: it might cause the div.content has same height of the picture, so if div.content have any children that placed according to its height, you might want set a number not something like 'auto'.

rt.jar contains all of the compiled class files for the base Java Runtime environment. You should not be messing with this jar file.

For MacOS it is called classes.jar and located under /System/Library/Frameworks/<java_version>/Classes . Same not messing with it rule applies there as well :).

To diagnose it, follow this answer.

But to fix it, knowing you are the only one changing it, do:
1 - backup your project (I did only the files on git, ./src folder)
2 - git pull
3 - restore you backup over the many "messed" files (with merge indicators)

I tried git pull -s recursive -X ours but didnt work the way I wanted, it could be an option tho, but backup first!!!

Make sure the differences/changes (at git gui) are none. This is my case, there is nothing to merge at all, but github keeps saying I should merge...

Try this simple query. It works perfectly.

select * from Table1 where (FirstName,LastName,BirthDate) not in (select * from Table2);

With JavaScript:

var input = document.createElement("input");
input.type = "text";
input.className = "css-class-name"; // set the CSS class
container.appendChild(input); // put it into the DOM

Use \0.

color: green\0;

I however do recommend conditional comments since you'd like to exclude IE9 as well and it's yet unpredictable whether this hack will affect IE9 as well or not.

Regardless, I've never had the need for an IE8 specific hack. What is it, the IE8 specific problem which you'd like to solve? Is it rendering in IE8 standards mode anyway? Its renderer is pretty good.

Just add another join:

SELECT dashboard_data.headline,
       dashboard_data.message,
       dashboard_messages.image_id,
       images.filename 
FROM dashboard_data 
    INNER JOIN dashboard_messages
            ON dashboard_message_id = dashboard_messages.id 
    INNER JOIN images
            ON dashboard_messages.image_id = images.image_id

Just found that .Net Framework 4.5 now supports TLSv1.2
http://msdn.microsoft.com/en-us/library/system.security.authentication.sslprotocols(v=vs.110).aspx

This is a pretty clean way to do it:

myStr = ("firstPartOfMyString"+
         "secondPartOfMyString"+
         "thirdPartOfMyString")

 var link=document.createElement('a');
 document.body.appendChild(link);
 link.href=url;
 link.click();

Here's an example for rotating about an arbitrary point (x,y) using only openCV

def rotate_about_point(x, y, degree, image):
    rot_mtx = cv.getRotationMatrix2D((x, y), angle, 1)
    abs_cos = abs(rot_mtx[0, 0])
    abs_sin = abs(rot_mtx[0, 1])
    rot_wdt = int(frm_hgt * abs_sin + frm_wdt * abs_cos)
    rot_hgt = int(frm_hgt * abs_cos + frm_wdt * abs_sin)
    rot_mtx += np.asarray([[0, 0, -lftmost_x],
                           [0, 0, -topmost_y]])
    rot_img = cv.warpAffine(image, rot_mtx, (rot_wdt, rot_hgt),
                            borderMode=cv.BORDER_CONSTANT)
    return rot_img

Had this happen in a team using git. One of the team members added a class from an external source but didn't copy it into the repo directory. The local version compiled fine but the continuous integration failed with this error.

Reimporting the files and adding them to the directory under version control fixed it.

You can also try git diff --word-diff. It's not exactly side-by-side, but somehow better, so you might prefer it to your actual side-by-side need.

Send params from View to an other View, from Sender View to Receiver View use viewParam and includeViewParams=true

In Sender

1. Declare params to be sent. We can send String, Object,…

Sender.xhtml

<f:metadata>
      <f:viewParam name="ID" value="#{senderMB._strID}" />
</f:metadata>

2. We’re going send param ID, it will be included with “includeViewParams=true” in return String of click button event Click button fire senderMB.clickBtnDetail(dto) with dto from senderMB._arrData

Sender.xhtml

<p:dataTable rowIndexVar="index" id="dataTale"value="#{senderMB._arrData}" var="dto">
      <p:commandButton action="#{senderMB.clickBtnDetail(dto)}" value="??" 
      ajax="false"/>
</p:dataTable>

In senderMB.clickBtnDetail(dto) we assign _strID with argument we got from button event (dto), here this is Sender_DTO and assign to senderMB._strID

Sender_MB.java
    public String clickBtnDetail(sender_DTO sender_dto) {
        this._strID = sender_dto.getStrID();
        return "Receiver?faces-redirect=true&includeViewParams=true";
    }

The link when clicked will become http://localhost:8080/my_project/view/Receiver.xhtml?*ID=12345*

In Recever

1. Get viewParam Receiver.xhtml In Receiver we declare f:viewParam to get param from get request (receive), the name of param of receiver must be the same with sender (page)

Receiver.xhtml

<f:metadata><f:viewParam name="ID" value="#{receiver_MB._strID}"/></f:metadata>

It will get param ID from sender View and assign to receiver_MB._strID

2. Use viewParam In Receiver, we want to use this param in sql query before the page render, so that we use preRenderView event. We are not going to use constructor because constructor will be invoked before viewParam is received So that we add

Receiver.xhtml

<f:event listener="#{receiver_MB.preRenderView}" type="preRenderView" />

into f:metadata tag

Receiver.xhtml

<f:metadata>
<f:viewParam name="ID" value="#{receiver_MB._strID}" />
<f:event listener="#{receiver_MB.preRenderView}"
            type="preRenderView" />
</f:metadata>

Now we want to use this param in our read database method, it is available to use

Receiver_MB.java
public void preRenderView(ComponentSystemEvent event) throws Exception {
        if (FacesContext.getCurrentInstance().isPostback()) {
            return;
        }
        readFromDatabase();
    }
private void readFromDatabase() {
//use _strID to read and set property   
}

"preflighted" requests first send an HTTP request by the OPTIONS method to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests

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

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

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

If you're using GitHub for Windows, git.exe may not be in your PATH, but you may find it in a location like: C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\bin\git.exe

That's the situation for me, in Windows 7 + version 1.0 of GitHub for Windows.

In Windows 10 it appears to be in:

C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\cmd\git.exe

( \cmd versus \bin)

From GitHub Desktop 1.1

The UI is different and the Git path now is in:

C:\Users\<username>\AppData\Local\GitHubDesktop\app-<appversion>\resources\app\git\cmd\git.exe

PS: AppData is a hidden folder by default.

I improved Salselvaprabu's answer in several ways:

1. It is now a function - you can put in your powershell profile and use anytime you need
2. It can accept host as hostname or as ip address
3. No more exceptions if host or port unavaible - just text

Call it like this:

Test-Port example.com 999
Test-Port 192.168.0.1 80

function Test-Port($hostname, $port)
{
    # This works no matter in which form we get $host - hostname or ip address
    try {
        $ip = [System.Net.Dns]::GetHostAddresses($hostname) | 
            select-object IPAddressToString -expandproperty  IPAddressToString
        if($ip.GetType().Name -eq "Object[]")
        {
            #If we have several ip's for that address, let's take first one
            $ip = $ip[0]
        }
    } catch {
        Write-Host "Possibly $hostname is wrong hostname or IP"
        return
    }
    $t = New-Object Net.Sockets.TcpClient
    # We use Try\Catch to remove exception info from console if we can't connect
    try
    {
        $t.Connect($ip,$port)
    } catch {}

    if($t.Connected)
    {
        $t.Close()
        $msg = "Port $port is operational"
    }
    else
    {
        $msg = "Port $port on $ip is closed, "
        $msg += "You may need to contact your IT team to open it. "                                 
    }
    Write-Host $msg
}

consider it as a raw string. Just simple answer, add r before your windows path.

import csv
data = open(r"C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener")
data = csv.reader(data)  
print(data)

You can store objects in a HashMap.

HashMap<String, Object> map = new HashMap<String, Object>();

You'll just need to cast it back out correctly.

There is a cleaner way with just one header file so it is simpler to maintain. In the header with the global variables prefix each declaration with a keyword (I use common) then in just one source file include it like this

#define common
#include "globals.h"
#undef common

and any other source files like this

#define common extern
#include "globals.h"
#undef common

Just make sure you don't initialise any of the variables in the globals.h file or the linker will still complain as an initialised variable is not treated as external even with the extern keyword. The global.h file looks similar to this

#pragma once
common int globala;
common int globalb;
etc.

seems to work for any type of declaration. Don't use the common keyword on #define of course.

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

also works. First create a JFrame called frame, then add this code underneath.

I made the following filter:

angular.module('app').filter('ifEmpty', function() {
    return function(input, defaultValue) {
        if (angular.isUndefined(input) || input === null || input === '') {
            return defaultValue;
        }

        return input;
    }
});

To be used like this:

<span>{{aPrice | currency | ifEmpty:'N/A'}}</span>
<span>{{aNum | number:3 | ifEmpty:0}}</span>

System.setProperty("gate.home", "/some/directory");
