Finally I found a solution - I'm posting it here for other people who might have the same problem (all 5 of you):

• Change the product ID to *

• Under product add The following:

  <Property Id="PREVIOUSVERSIONSINSTALLED" Secure="yes" />
  <Upgrade Id="YOUR_GUID">  
     <UpgradeVersion
        Minimum="1.0.0.0" Maximum="99.0.0.0"
        Property="PREVIOUSVERSIONSINSTALLED"
        IncludeMinimum="yes" IncludeMaximum="no" />
  </Upgrade> 
  

• Under InstallExecuteSequence add:

  <RemoveExistingProducts Before="InstallInitialize" /> 
  

From now on whenever I install the product it removed previous installed versions.

Note: replace upgrade Id with your own GUID

you could also do it this way, in my case i use it before and after an h1 (brute force it ehehehe)

.titleImage::before {
content: "--------";
letter-spacing: -3px;
}

.titreImage::after {
content: "--------";
letter-spacing: -3px;
}

If the letter spacing makes it so the line get in the text just use a margin to push it away!

base

read.csv without the url function just works fine. Probably I am missing something if Dirk Eddelbuettel included it in his answer:

ad <- read.csv("http://www-bcf.usc.edu/~gareth/ISL/Advertising.csv")
head(ad)

  X    TV radio newspaper sales
1 1 230.1  37.8      69.2  22.1

6 6   8.7  48.9      75.0   7.2

Another options using two popular packages:

data.table

library(data.table)
ad <- fread("http://www-bcf.usc.edu/~gareth/ISL/Advertising.csv")
head(ad)

6:  6   8.7  48.9      75.0   7.2

readr

library(readr)
ad <- read_csv("http://www-bcf.usc.edu/~gareth/ISL/Advertising.csv")
head(ad)

6     6   8.7  48.9      75.0   7.2

This is how did it works like a charm.

CSS

#loader {
position:fixed;
left:1px;
top:1px;
width: 100%;
height: 100%;
z-index: 9999;

background: url('../images/ajax-loader100X100.gif') 50% 50% no-repeat rgb(249,249,249);
}  

in _layout file inside body tag but outside the container div. Every time page loads it shows loading. Once page is loaded JS fadeout(second)

<div id="loader">
</div>

JS at the bottom of _layout file

<script type="text/javascript">
// With the element initially shown, we can hide it slowly:
 $("#loader").fadeOut(1000);
</script>  

You can get the milliseconds since 1/1/1970 using such code:

private static DateTime JanFirst1970 = new DateTime(1970, 1, 1);
public static long getTime()
{
    return (long)((DateTime.Now.ToUniversalTime() - JanFirst1970).TotalMilliseconds + 0.5);
}

I couldn't figure out how to do this in pure MS LINQ, so I wrote my own extension method to do it:

public static bool In<T>(this T objToCheck, params T[] values)
{
    if (values == null || values.Length == 0) 
    {
        return false; //early out
    }
    else
    {
        foreach (T t in values)
        {
            if (t.Equals(objToCheck))
                return true;   //RETURN found!
        }

        return false; //nothing found
    }
}

I was also getting the same problem, but i uninstalled all updates of java and now it is working very fine....

Something like this:

ARGV.each do|a|
  puts "Argument: #{a}"
end

then

$ ./test.rb "test1 test2"

or

v1 = ARGV[0]
v2 = ARGV[1]
puts v1       #prints test1
puts v2       #prints test2

I think this is what you want:

JavaScriptSerializer JSS = new JavaScriptSerializer();
T obj = JSS.Deserialize<T>(String);

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

Are the classes imported? Try pressing CTRL + SHIFT + O to resolve the imports. If this does not work you need to include the application servers runtime libraries.

1. Windows > Preferences
2. Server > Runtime Environment
3. Add
4. Select your appropriate environment, click Next
5. Point to the install directory and click Finish.

Maybe not better but in my opinion more readable is to create an extension method

public static bool IsNull(this object obj) {
 return obj == null;
}

Your error

Notice: Trying to get property of non-object in C:\wamp\www\phone\pages\init.php on line 22

Your comment

@22 is <?php echo $sidemenu->mname."<br />";?>

$sidemenu is not an object, and you are trying to access one of its properties.

That is the reason for your error.

purrr::flatten_*() is also a good option. the flatten_* functions add thin sanity checks and ensure type safety.

myList <- list('A'=1, 'B'=2, 'C'=3)

purrr::flatten_dbl(myList)
## [1] 1 2 3

Use the built in collection methods contain and find, which will search by primary ids (instead of array keys). Example:

if ($model->collection->contains($primaryId)) {
    var_dump($model->collection->find($primaryId);
}

contains() actually just calls find() and checks for null, so you could shorten it down to:

if ($myModel = $model->collection->find($primaryId)) {
    var_dump($myModel);
}

If you just run jmap -histo:live or jmap -histo, it outputs the contents on the console!

Well, you can use Expression.AndAlso / OrElse etc to combine logical expressions, but the problem is the parameters; are you working with the same ParameterExpression in expr1 and expr2? If so, it is easier:

var body = Expression.AndAlso(expr1.Body, expr2.Body);
var lambda = Expression.Lambda<Func<T,bool>>(body, expr1.Parameters[0]);

This also works well to negate a single operation:

static Expression<Func<T, bool>> Not<T>(
    this Expression<Func<T, bool>> expr)
{
    return Expression.Lambda<Func<T, bool>>(
        Expression.Not(expr.Body), expr.Parameters[0]);
}

Otherwise, depending on the LINQ provider, you might be able to combine them with Invoke:

// OrElse is very similar...
static Expression<Func<T, bool>> AndAlso<T>(
    this Expression<Func<T, bool>> left,
    Expression<Func<T, bool>> right)
{
    var param = Expression.Parameter(typeof(T), "x");
    var body = Expression.AndAlso(
            Expression.Invoke(left, param),
            Expression.Invoke(right, param)
        );
    var lambda = Expression.Lambda<Func<T, bool>>(body, param);
    return lambda;
}

Somewhere, I have got some code that re-writes an expression-tree replacing nodes to remove the need for Invoke, but it is quite lengthy (and I can't remember where I left it...)

Generalized version that picks the simplest route:

static Expression<Func<T, bool>> AndAlso<T>(
    this Expression<Func<T, bool>> expr1,
    Expression<Func<T, bool>> expr2)
{
    // need to detect whether they use the same
    // parameter instance; if not, they need fixing
    ParameterExpression param = expr1.Parameters[0];
    if (ReferenceEquals(param, expr2.Parameters[0]))
    {
        // simple version
        return Expression.Lambda<Func<T, bool>>(
            Expression.AndAlso(expr1.Body, expr2.Body), param);
    }
    // otherwise, keep expr1 "as is" and invoke expr2
    return Expression.Lambda<Func<T, bool>>(
        Expression.AndAlso(
            expr1.Body,
            Expression.Invoke(expr2, param)), param);
}

Starting from .NET 4.0, there is the ExpressionVisitor class which allows you to build expressions that are EF safe.

    public static Expression<Func<T, bool>> AndAlso<T>(
        this Expression<Func<T, bool>> expr1,
        Expression<Func<T, bool>> expr2)
    {
        var parameter = Expression.Parameter(typeof (T));

        var leftVisitor = new ReplaceExpressionVisitor(expr1.Parameters[0], parameter);
        var left = leftVisitor.Visit(expr1.Body);

        var rightVisitor = new ReplaceExpressionVisitor(expr2.Parameters[0], parameter);
        var right = rightVisitor.Visit(expr2.Body);

        return Expression.Lambda<Func<T, bool>>(
            Expression.AndAlso(left, right), parameter);
    }



    private class ReplaceExpressionVisitor
        : ExpressionVisitor
    {
        private readonly Expression _oldValue;
        private readonly Expression _newValue;

        public ReplaceExpressionVisitor(Expression oldValue, Expression newValue)
        {
            _oldValue = oldValue;
            _newValue = newValue;
        }

        public override Expression Visit(Expression node)
        {
            if (node == _oldValue)
                return _newValue;
            return base.Visit(node);
        }
    }

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

#answer,
#show,
#hide:target {
    display: none; 
}

#hide:target + #show,
#hide:target ~ #answer {
    display: inherit; 
}

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

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

Using jQuery:

function doSomething(element) {
    var form = $(element).closest("form").get().
    //do something with the form.
}

this has been modified in codeigniter 2.2.1...usually not best practice to modify core files, I would always check for updates and 2.2.1 came out in Jan 2015

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

/**
 * Document my Jenkinsfile's overall purpose here
 */

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

Running eclipse and also running Maven will require you to store two path variables, one in your jdk1.7_x_x_x location and also in your jdk1.7_x_x_\bin. If you are using Windows, when you are in your environment variables, do the following:

1) create a USER variable called JAVA_HOME. Point this to the location of your JAVA file. For example: "C:\Program Files\Java\jdk1.7.0_51" (remove the quotes)

2) under the PATH, append %JAVA_HOME% to the PATH. This will add the file location from step 1 to your PATH. This is good for MAVEN

3) if you are using eclipse you need to have the path point to "C:\Program Files\Java\jdk1.7.0_51\bin". Now append %JAVA_HOME%\bin to the end of your path.

4) your path should look something like this: C:\Program Files (x86)\Google\google_appengine\;C:\Users\username\AppData\Roaming\npm;%M2%;%JAVA_HOME%;%JAVA_HOME%\bin

Notes: the items that are enclosed in %'s like %M2% are assigned variables. It looks redundant but necessary. You can confirm that everything works by typing in:

java -version
javac -version
mvn -version

Each of those three statements typed in comman prompt should not return errors.

Try this, it's working for me.

Sender:

byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

dOut.writeInt(message.length); // write length of the message
dOut.write(message);           // write the message

Receiver:

Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());

int length = dIn.readInt();                    // read length of incoming message
if(length>0) {
    byte[] message = new byte[length];
    dIn.readFully(message, 0, message.length); // read the message
}

Regex.Split can extract numbers from strings. You get all the numbers that are found in a string.

string input = "There are 4 numbers in this string: 40, 30, and 10.";
// Split on one or more non-digit characters.
string[] numbers = Regex.Split(input, @"\D+");
foreach (string value in numbers)
{
    if (!string.IsNullOrEmpty(value))
    {
    int i = int.Parse(value);
    Console.WriteLine("Number: {0}", i);
    }
}

Output:

Number: 4 Number: 40 Number: 30 Number: 10

ThisWorkbook.Worksheets("Master").Sheet1.Cells.Copy _
    Destination:=newWorksheet.Cells

The above will copy the cells. If you really want to duplicate the entire sheet, then I'd go with @brettdj's answer.

The way to "start" the array that you want is:

arr = np.empty((0,3), int)

Which is an empty array but it has the proper dimensionality.

>>> arr
array([], shape=(0, 3), dtype=int64)

Then be sure to append along axis 0:

arr = np.append(arr, np.array([[1,2,3]]), axis=0)
arr = np.append(arr, np.array([[4,5,6]]), axis=0)

But, @jonrsharpe is right. In fact, if you're going to be appending in a loop, it would be much faster to append to a list as in your first example, then convert to a numpy array at the end, since you're really not using numpy as intended during the loop:

In [210]: %%timeit
   .....: l = []
   .....: for i in xrange(1000):
   .....:     l.append([3*i+1,3*i+2,3*i+3])
   .....: l = np.asarray(l)
   .....: 
1000 loops, best of 3: 1.18 ms per loop

In [211]: %%timeit
   .....: a = np.empty((0,3), int)
   .....: for i in xrange(1000):
   .....:     a = np.append(a, 3*i+np.array([[1,2,3]]), 0)
   .....: 
100 loops, best of 3: 18.5 ms per loop

In [214]: np.allclose(a, l)
Out[214]: True

The numpythonic way to do it depends on your application, but it would be more like:

In [220]: timeit n = np.arange(1,3001).reshape(1000,3)
100000 loops, best of 3: 5.93 µs per loop

In [221]: np.allclose(a, n)
Out[221]: True

It's not going anywhere ... it's a new standard C++ feature in the implementation of C++11. That being said, while it's a wonderful tool for simplifying object declarations as well as cleaning up the syntax for certain call-paradigms (i.e., range-based for-loops), don't over-use/abuse it :-)

@Resource annotation on field level also could be used to declare look up at runtime

Here is a working solution in windows 10 that does not include any third-party components. It works by wrapping the PowerShell script into VBScript.

Step 1: we need to change some windows features to allow VBScript to run PowerShell and to open .ps1 files with PowerShell by default.

-go to run and type "regedit". Click on ok and then allow it to run.

-paste this path "HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell" and press enter.

-now open the entry on the right and change the value to 0.

-open PowerShell as an administrator and type "Set-ExecutionPolicy -ExecutionPolicy RemoteSigned", press enter and confirm the change with "y" and then enter.

Step 2: Now we can start wrapping our script.

-save your Powershell script as a .ps1 file.

-create a new text document and paste this script.

Dim objShell,objFSO,objFile

Set objShell=CreateObject("WScript.Shell")
Set objFSO=CreateObject("Scripting.FileSystemObject")

'enter the path for your PowerShell Script
 strPath="c:\your script path\script.ps1"

'verify file exists
 If objFSO.FileExists(strPath) Then
   'return short path name
   set objFile=objFSO.GetFile(strPath)
   strCMD="powershell -nologo -command " & Chr(34) & "&{" &_
    objFile.ShortPath & "}" & Chr(34)
   'Uncomment next line for debugging
   'WScript.Echo strCMD

  'use 0 to hide window
   objShell.Run strCMD,0

Else

  'Display error message
   WScript.Echo "Failed to find " & strPath
   WScript.Quit

End If

-now change the file path to the location of your .ps1 script and save the text document.

-Now right-click on the file and go to rename. Then change the filename extension to .vbs and press enter and then click ok.

DONE! If you now open the .vbs you should see no console window while your script is running in the background.

make sure to upvote if this worked for you!

<select name="foo" id="foo">
 <option value="1">a</option>
 <option value="2">b</option>
 <option value="3">c</option>
  </select>
  <input type="button" id="button" value="Button" />
  });
  <script> ("#foo").val() </script>

which returns 1 if you have selected a and so on..

TO answer your question: no, MySQL does not support Table-typed variables in the same manner that SQL Server (http://msdn.microsoft.com/en-us/library/ms188927.aspx) provides. Oracle provides similar functionality but calls them Cursor types instead of table types (http://docs.oracle.com/cd/B12037_01/appdev.101/b10807/13_elems012.htm).

Depending your needs you can simulate table/cursor-typed variables in MySQL using temporary tables in a manner similar to what is provided by both Oracle and SQL Server.

However, there is an important difference between the temporary table approach and the table/cursor-typed variable approach and it has a lot of performance implications (this is the reason why Oracle and SQL Server provide this functionality over and above what is provided with temporary tables).

Specifically: table/cursor-typed variables allow the client to collate multiple rows of data on the client side and send them up to the server as input to a stored procedure or prepared statement. What this eliminates is the overhead of sending up each individual row and instead pay that overhead once for a batch of rows. This can have a significant impact on overall performance when you are trying to import larger quantities of data.

A possible work-around:

What you may want to try is creating a temporary table and then using a LOAD DATA (http://dev.mysql.com/doc/refman/5.1/en/load-data.html) command to stream the data into the temporary table. You could then pass them name of the temporary table into your stored procedure. This will still result in two calls to the database server, but if you are moving enough rows there may be a savings there. Of course, this is really only beneficial if you are doing some kind of logic inside the stored procedure as you update the target table. If not, you may just want to LOAD DATA directly into the target table.

For Bootstrap 3, there is

placement: 'auto right'

which is easier. By default, it will be right, but if the element is located in the right side of the screen, the popover will be left. So it should be:

$('.infopoint').popover({
   trigger:'hover',
   animation: false,
   placement: 'auto right'
});

I was facing same issue not able to post form without ajax. but found solution , hope it can help and someones time.

<form name="paymentitrform" id="paymentitrform" class="payment"
                    method="post"
                    action="abc.php">
          <input name="email" value="" placeholder="email" />
          <input type="hidden" name="planamount" id="planamount" value="0">
                                <input type="submit" onclick="form_submit() " value="Continue Payment" class="action"
                                    name="planform">

                </form>

You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button

    function form_submit() {
        document.getElementById("paymentitrform").submit();
   }  

Try this:

var array = [1, 55, 77, 88, 76, 59];
var array_last_five;
array_last_five = array.slice(-5);
if (array.length < 6) {
     array_last_five.shift();
}

The accepted answer did not work for me when using Django 1.4.4. Instead of the raw query, a reference to the Query object was returned: <django.db.models.sql.query.Query object at 0x10a4acd90>.

The following returned the query:

>>> queryset = MyModel.objects.all()
>>> queryset.query.__str__()

Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.

# in your PHP code:
ini_set('display_errors', '0');     # don't show any errors...
error_reporting(E_ALL | E_STRICT);  # ...but do log them

They will be logged to your standard system log, or use the error_log directive to specify exactly where you want errors to go.

Here "\n" is also working fine. But the problem here lies in the text editor(probably notepad). Try to see the output with Wordpad.

On the "How to do it" part:

I think the introduction to ScalaTest does good job of illustrating different styles of unit tests.

On the "When to do it" part:

Unit testing is not only for testing. By doing unit testing you also force the design of the software into something that is unit testable. Many people are of the opinion that this design is for the most part Good Design(TM) regardless of other benefits from testing.

So one reason to do unit test is to force your design into something that hopefully will be easier to maintain that what it would be had you not designed it for unit testing.

My problem was, that Visual Studio somehow automatically lowercased *ngFor to *ngfor on copy&paste.

I think some folks here haven't really focused on your particular question. It looks like the problem you have is in putting the random number in the page and hooking the player up to it. There are a number of ways to do that. The simplest is with a small change to your existing code like this to document.write() the result into the page. I wouldn't normally recommend document.write(), but since your code is already inline and what you were trying do already was to put the div inline, this is the simplest way to do that. At the point where you have the random number, you just use this to put it and the div into the page:

var randomId = "x" + randomString(8);
document.write('<div id="' + randomId + '">This text will be replaced</div>');

and then, you refer to that in the jwplayer set up code like this:

jwplayer(randomId).setup({

And the whole block of code would look like this:

<script type='text/javascript' src='jwplayer.js'></script>
<script type='text/javascript'>
function randomString(length) {
    var chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghiklmnopqrstuvwxyz'.split('');

    if (! length) {
        length = Math.floor(Math.random() * chars.length);
    }

    var str = '';
    for (var i = 0; i < length; i++) {
        str += chars[Math.floor(Math.random() * chars.length)];
    }
    return str;
}

var randomId = "x" + randomString(8);
document.write('<div id="' + randomId + '">This text will be replaced</div>'); 

  jwplayer(randomId).setup({
    'flashplayer': 'player.swf',
    'file': 'http://www.youtube.com/watch?v=4AX0bi9GXXY',
    'controlbar': 'bottom',
    'width': '470',
    'height': '320'
  });
</script>

Another way to do it

I might add here at the end that generating a truly random number just to create a unique div ID is way overkill. You don't need a random number. You just need an ID that won't otherwise exist in the page. Frameworks like YUI have such a function and all they do is have a global variable that gets incremented each time the function is called and then combine that with a unique base string. It can look something like this:

var generateID = (function() {
    var globalIdCounter = 0;
    return function(baseStr) {
        return(baseStr + globalIdCounter++);
    }
})();

And, then in practical use, you would do something like this:

var randomId = generateID("myMovieContainer");  // "myMovieContainer1"
document.write('<div id="' + randomId + '">This text will be replaced</div>');
jwplayer(randomId).setup({

Try checking his post. It shows how to implement transitions between web pages using AngularJS's ngRoute and ngAnimate: How to Make iPhone-Style Web Page Transitions Using AngularJS & CSS

I use the way shown below. It submits everything like files.

$(document).on("submit", "form", function(event)
{
    event.preventDefault();

    var url  = $(this).attr("action");
    $.ajax({
        url: url,
        type: 'POST',
        dataType: "JSON",
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        },
        error: function (xhr, desc, err)
        {
            console.log("error");
        }
    });
});

You could try argmax like this:

dataframe['name'].value_counts().argmax() Out[13]: 'alex'

The value_counts will return a count object of pandas.core.series.Series and argmax could be used to achieve the key of max values.

If you put #!/bin/awk -f on the first line of your AWK script it is easier. Plus editors like Vim and ... will recognize the file as an AWK script and you can colorize. :)

#!/bin/awk -f
BEGIN {}  # Begin section
{}        # Loop section
END{}     # End section

Change the file to be executable by running:

chmod ugo+x ./awk-script

and you can then call your AWK script like this:

`$ echo "something" | ./awk-script`

This is a pre-commit hook which replaces the symlink blobs in the index, with the content of those symlinks.

Put this in .git/hooks/pre-commit, and make it executable:

#!/bin/sh
# (replace "find ." with "find ./<path>" below, to work with only specific paths)

# (these lines are really all one line, on multiple lines for clarity)
# ...find symlinks which do not dereference to directories...
find . -type l -exec test '!' -d {} ';' -print -exec sh -c \
# ...remove the symlink blob, and add the content diff, to the index/cache
    'git rm --cached "$1"; diff -au /dev/null "$1" | git apply --cached -p1 -' \
# ...and call out to "sh".
    "process_links_to_nondir" {} ';'

# the end

Notes

We use POSIX compliant functionality as much as possible; however, diff -a is not POSIX compliant, possibly among other things.

There may be some mistakes/errors in this code, even though it was tested somewhat.

For any googlers like me, where..

.btn:focus {
    outline: none;
}

still didn't work in Google Chrome, the following should completely remove any button glow.

.btn:focus,.btn:active:focus,.btn.active:focus,
.btn.focus,.btn:active.focus,.btn.active.focus {
    outline: none;
}

For what you want I would've used

    app.get('/fruit/:fruitName&:fruitColor', function(request, response) {
       const name = request.params.fruitName 
       const color = request.params.fruitColor 
    });

or better yet

    app.get('/fruit/:fruit', function(request, response) {
       const fruit = request.params.fruit
       console.log(fruit)
    });

where fruit is a object. So in the client app you just call

https://mydomain.dm/fruit/{"name":"My fruit name", "color":"The color of the fruit"}

and as a response you should see:

    //  client side response
    // { name: My fruit name, color:The color of the fruit}

add a space character too the string. that's poor man's padding :)

OR

I would go with a custom background view but if you don't want that, the space is the only other easy options I see...

OR write a custom label. render the text via coretext

Directly install one of the fink packages (Django 1.6 as of 2013-Nov)

fink install django-py27
fink install django-py33

Or create yourself a virtualenv:

fink install virtualenv-py27
virtualenv django-env
source django-env/bin/activate
pip install django
deactivate # when you are done

Or use fink django plus any other pip installed packages in a virtualenv

fink install django-py27
fink install virtualenv-py27
virtualenv django-env --system-site-packages
source django-env/bin/activate
# django already installed
pip install django-analytical # or anything else you might want
deactivate # back to your normally scheduled programming

Of course there is. Check out mysql_query, and mysql_fetch_row if you use MySQL.
Example from PHP manual:

<?php
$result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$row = mysql_fetch_row($result);

echo $row[0]; // 42
echo $row[1]; // the email value
?>

For some databases, you can just explicitly insert a NULL into the auto_increment column:

INSERT INTO table_name VALUES (NULL, 'my name', 'my group')

That's depending if userid is a resource identifier or additional parameter. If it is then it's ok to return 404 if not you might return other code like

400 (bad request) - indicates a bad request
or
412 (Precondition Failed) e.g. conflict by performing conditional update

More info in free InfoQ Explores: REST book.

Prefix you literal with 0b like in

int i = 0b11111111;

See here.

Because you did not write a comparison operator for your struct. The compiler does not generate it for you, so if you want comparison, you have to write it yourself.

Yes, they both form the primary key. Especially in tables where you don't have a surrogate key, it may be necessary to specify multiple attributes as the unique identifier for each record (bad example: a table with both a first name and last name might require the combination of them to be unique).

If you are using prototype.js then you can do this:

transport_select.observe('change', function(){
  toggleSelect(transport_select_id)
})

This eliminate (as hope) the problem in cross-browsers

From JavaNotes:

• a.compareTo(b):
  Comparable interface : Compares values and returns an int which tells if the values compare less than, equal, or greater than.
  If your class objects have a natural order, implement the Comparable<T> interface and define this method. All Java classes that have a natural ordering implement Comparable<T> - Example: String, wrapper classes, BigInteger

• compare(a, b):
  Comparator interface : Compares values of two objects. This is implemented as part of the Comparator<T> interface, and the typical use is to define one or more small utility classes that implement this, to pass to methods such as sort() or for use by sorting data structures such as TreeMap and TreeSet. You might want to create a Comparator object for the following:

  • Multiple comparisons. To provide several different ways to sort something. For example, you might want to sort a Person class by name, ID, age, height, ... You would define a Comparator for each of these to pass to the sort() method.
  • System class To provide comparison methods for classes that you have no control over. For example, you could define a Comparator for Strings that compared them by length.
  • Strategy pattern To implement a Strategy pattern, which is a situation where you want to represent an algorithm as an object that you can pass as a parameter, save in a data structure, etc.

If your class objects have one natural sorting order, you may not need compare().

Summary from http://www.digizol.com/2008/07/java-sorting-comparator-vs-comparable.html

Comparable
A comparable object is capable of comparing itself with another object.

Comparator
A comparator object is capable of comparing two different objects. The class is not comparing its instances, but some other class’s instances.

Use case contexts:

Comparable interface

The equals method and == and != operators test for equality/inequality, but do not provide a way to test for relative values.
Some classes (eg, String and other classes with a natural ordering) implement the Comparable<T> interface, which defines a compareTo() method.
You will want to implement Comparable<T> in your class if you want to use it with Collections.sort() or Arrays.sort() methods.

Defining a Comparator object

You can create Comparators to sort any arbitrary way for any class.
For example, the String class defines the CASE_INSENSITIVE_ORDER comparator.

The difference between the two approaches can be linked to the notion of:
Ordered Collection:

When a Collection is ordered, it means you can iterate in the collection in a specific (not-random) order (a Hashtable is not ordered).

A Collection with a natural order is not just ordered, but sorted. Defining a natural order can be difficult! (as in natural String order).

Another difference, pointed out by HaveAGuess in the comments:

• Comparable is in the implementation and not visible from the interface, so when you sort you don't really know what is going to happen.
• Comparator gives you reassurance that the ordering will be well defined.

I've been exploring this topic for some days and here is what I found. Options fall into two categories:

If you want to build a desktop app the best options are:

1- NW.js: lets you call all Node.js modules directly from DOM and enables a new way of writing applications with all Web technologies.

2- Electron: Build cross platform desktop apps with JavaScript, HTML, and CSS

Here is a good comparison between them: NW.js & Electron Compared. I think NW.js is better and it also provides an application to compile JS files. There are also some standalone executable and installer builders like Enigma Virtual Box. They both contain an embedded version of Chrome which is unnecessary for server apps.

if you want to package a server app these are the best options:

node-compiler: Ahead-of-time (AOT) Compiler designed for Node.js, that just works.

Nexe: create a single executable out of your node.js apps

In this category, I believe node-compiler is better which supports dynamic require and native node modules. It's very easy to use and the output starts at 25MB. You can read a full comparison with other solutions in Node Compiler page. I didn't read much about Nexe, but for now, it seems Node Compiler doesn't compile the js file to binary format using V8 snapshot feature but it's planned for version 2. It's also going to have built-in installer builder.

I had exactly the same issue, and after many hours of debugging, I found out it was because I was accessing a subscript by using .subscript() instead of between []. XCode thinks this is perfectly valid, but gives this segmentation fault error when building.

If the BorderLayout option provided by our friends doesnot work, try adding ComponentListerner to the JFrame and implement the componentResized(event) method. When the JFrame object will be resized, this method will be called. So if you write the the code to set the size of the JPanel in this method, you will achieve the intended result.

Ya, I know this 'solution' is not good but use it as a safety net. ;)

check this fiddle,

i just edited the above fiddle, its working

http://jsfiddle.net/narensrinivasans/FpNxn/1/

.selectDefault, .selectDiv option
{
    font-family:arial;
    font-size:12px;
}

What you need are character classes. In that, you've only to worry about the ], \ and - characters (and ^ if you're placing it straight after the beginning of the character class "[" ).

Syntax: [characters] where characters is a list with characters.

Example:

var cleanString = dirtyString.replace(/[|&;$%@"<>()+,]/g, "");

The user parameter of your callback is an array with find. Use findOne instead of find when querying for a single instance.

User.findOne({username: oldUsername}, function (err, user) {
    user.username = newUser.username;
    user.password = newUser.password;
    user.rights = newUser.rights;

    user.save(function (err) {
        if(err) {
            console.error('ERROR!');
        }
    });
});

JSP implicit objects likes session, request etc. are not available inside JSP declaration <%! %> tags.

You could use it directly in your expression as

<td>Username: </td>
<td><input type="text" value="<%= session.getAttribute("username") %>" /></td>

On other note, using scriptlets in JSP has been long deprecated. Use of EL (expression language) and JSTL tags is highly recommended. For example, here you could use EL as

<td>Username: </td>
<td><input type="text" value="${username}" /></td>

The best part is that scope resolution is done automatically. So, here username could come from page, or request, or session, or application scopes in that order. If for a particular instance you need to override this because of a name collision you can explicitly specify the scope as

<td><input type="text" value="${requestScope.username}" /></td> or,
<td><input type="text" value="${sessionScope.username}" /></td> or,
<td><input type="text" value="${applicationScope.username}" /></td>

You can use this function if it's multiple string df[!grepl("REVERSE|GENJJS", df$Name),]

Please don't use techniques described in other answers here. They are either not working with css3 animations size changes, floating layout changes or changes that don't come from jQuery land. You can use a resize-detector, a event-based approach, that doesn't waste your CPU time.

https://github.com/marcj/css-element-queries

It contains a ResizeSensor class you can use for that purpose.

new ResizeSensor(jQuery('#mainContent'), function(){ 
    console.log('main content dimension changed');
});

Disclaimer: I wrote this library

I don't think there's any one right answer to this question, but my advice would be to stick with SWT unless you are encountering severe limitations that require such a massive overhaul.

Also, SWT is actually newer and more actively maintained than Swing. (It was originally developed as a replacement for Swing using native components).

You have to use == to compare (or even ===, if you want to compare types). A single = is for assignment.

if (one == 'rock' && two == 'rock') {
    console.log('Tie! Try again!');
}

try it. it will works, enjoy

This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.

1. Do pip install python-dotenv in your environment (the same as being pointed to by pycharm).

2. Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console

3. In "starting script" include something like this near the top:

   from dotenv import load_dotenv load_dotenv(verbose=True)

The .env file can look like this: export KEY=VALUE

It doesn't matter if one includes export or not for dotenv to read it.

As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.

Check The data you are writing to Server. May be data has delimiter which is not used.

like

045|2272575|0.000|0.000|2013-10-07
045|2272585|0.000|0.000;2013-10-07

your delimiter is '|' but data has a delimiter ';'. So for this you are getting the error.

With HTML 5 we can use a new feature "required" the just add it to the tag which you want to be required like:

<input type='text' required>

The 'ours' in Git is referring to the original working branch which has authoritative/canonical part of git history.

The 'theirs' refers to the version that holds the work in order to be rebased (changes to be replayed onto the current branch).

This may appear to be swapped to people who are not aware that doing rebasing (e.g. git rebase) is actually taking your work on hold (which is theirs) in order to replay onto the canonical/main history which is ours, because we're rebasing our changes as third-party work.

The documentation for git-checkout was further clarified in Git >=2.5.1 as per f303016 commit:

--ours --theirs

When checking out paths from the index, check out stage #2 ('ours') or #3 ('theirs') for unmerged paths.

Note that during git rebase and git pull --rebase, 'ours' and 'theirs' may appear swapped; --ours gives the version from the branch the changes are rebased onto, while --theirs gives the version from the branch that holds your work that is being rebased.

This is because rebase is used in a workflow that treats the history at the remote as the shared canonical one, and treats the work done on the branch you are rebasing as the third-party work to be integrated, and you are temporarily assuming the role of the keeper of the canonical history during the rebase. As the keeper of the canonical history, you need to view the history from the remote as ours (i.e. "our shared canonical history"), while what you did on your side branch as theirs (i.e. "one contributor's work on top of it").

For git-merge it's explain in the following way:

ours

This option forces conflicting hunks to be auto-resolved cleanly by favoring our version. Changes from the other tree that do not conflict with our side are reflected to the merge result. For a binary file, the entire contents are taken from our side.

This should not be confused with the ours merge strategy, which does not even look at what the other tree contains at all. It discards everything the other tree did, declaring our history contains all that happened in it.

theirs

This is the opposite of ours.

Further more, here is explained how to use them:

The merge mechanism (git merge and git pull commands) allows the backend merge strategies to be chosen with -s option. Some strategies can also take their own options, which can be passed by giving -X<option> arguments to git merge and/or git pull.

So sometimes it can be confusing, for example:

• git pull origin master where -Xours is our local, -Xtheirs is theirs (remote) branch
• git pull origin master -r where -Xours is theirs (remote), -Xtheirs is ours

So the 2nd example is opposite to the 1st one, because we're rebasing our branch on top of the remote one, so our starting point is remote one, and our changes are treated as external.

Similar for git merge strategies (-X ours and -X theirs).

Even though we have the .NPMRC can be in 3 locations, Please NOTE THAT - the file under the Per-User NPM config location take precedence over the Global & Built-in configurations.

1. Global NPM config => C:\Users\%username%\AppData\Roaming\npm\etc\npmrc
2. Per-user NPM config => C:\Users\%username%.npmrc
3. Built-in NPM config => C:\Program Files\nodejs\node_modules\npm\npmrc

To find out which file is getting updated, try setting the proxy using the following command npm config set https-proxy https://username:[email protected]:6050

After that open the .npmrc files to see which file get updated.

<?php
//None HttpOnly cookie:
setcookie("abc", "test", NULL, NULL, NULL, NULL, FALSE); 

//HttpOnly cookie:
setcookie("abc", "test", NULL, NULL, NULL, NULL, TRUE); 

?>

IIRC, the ConfigurationManager.RefreshSection requires a string parameter specifying the name of the Section to refresh :

ConfigurationManager.RefreshSection("connectionStrings");

I think that the ASP.NET application should automatically reload when the ConnectionStrings element is modified and the configuration does not need to be manually reloaded.

Another way is to use reflection:

protected T GetObject<T>(Type[] signature, object[] args)
{
    return (T)typeof(T).GetConstructor(signature).Invoke(args);
}

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

check this quick reminder of file path

Here is all you need to know about relative file paths:

• Starting with "/" returns to the root directory and starts there
• Starting with "../" moves one directory backwards and starts there
• Starting with "../../" moves two directories backwards and starts there (and so on...)
• To move forward, just start with the first subdirectory and keep moving forward

JPA was designed to provide an automatic mapping between Objects and a relational database. Since Integer is not a persistant entity, why do you need to use JPA ? A simple JDBC request will work fine.

Use xsd:include to bring in an XSD from the same or no namespace.

Use xsd:import to bring in an XSD from a different namespace.

Try this:

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

The above example will output:

While working on Windows 10 with Laragon and Laravel 4, it seemed to me there was no way to change the permissions manually, since executing chmod-commands in the Laragon-in-built-terminal had no effect.

However, it was possible in this terminal to go to the storage folder and manually add the desired folders like this:

cd app/storage
mkdir cache
mkdir meta
mkdir views
mkdir sessions

The cd-command in the terminal brings you to the folder (you might need to adjust this path to suit your file structure). The mkdir-command will create the directory with the given name.

I did not have the opportunity to test this approach in Laravel 5, but I expect that a similar approach should work.

Of course there might be a better way, but at least this was a reasonable workaround for my situation (fixing the error: file_put_contents(/var/www/html/laravel/app/storage/meta/services.json): failed to open stream).

If you want to delete elements from a list while iterating, use a while-loop so you can alter the current index and end index after each deletion.

Example:

i = 0
length = len(list1)

while i < length:
    if condition:
        list1.remove(list1[i])
        i -= 1
        length -= 1

    i += 1

You are doing it right with ServerCertificateValidationCallback. This is not the problem you are facing. The problem you are facing is most likely the version of SSL/TLS protocol.

For example, if your server offers only SSLv3 and TLSv10 and your client needs TLSv12 then you will receive this error message. What you need to do is to make sure that both client and server have a common protocol version supported.

When I need a client that is able to connect to as many servers as possible (rather than to be as secure as possible) I use this (together with setting the validation callback):

  ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

I think may be more automatic, grunt task usemin take care to do all this jobs for you, only need some configuration:

If you look at the definitions of @Controller, @Service annotations, then you'll find that these are special type of @Component annotation.

@Component
public @interface Service {
    ….
}

@Component
public @interface Controller {
    …
}

So what's the difference?

@Controller

The @Controller annotation indicates that a particular class serves the role of a controller. The @Controller annotation acts as a stereotype for the annotated class, indicating its role.

What’s special about @Controller?

You cannot switch this annotation with any other like @Service or @Repository, even though they look same. The dispatcher scans the classes annotated with @Controller and detects @RequestMapping annotations within them. You can only use @RequestMapping on @Controller annotated classes.

@Service

@Services hold business logic and call method in repository layer.

What’s special about @Service?

Apart from the fact that it is used to indicate that it's holding the business logic, there’s no noticeable specialty that this annotation provides, but who knows, spring may add some additional exceptional in future.

Linked answer: What's the difference between @Component, @Repository & @Service annotations in Spring?

Definitely works.

I have three answers to this question:

1. It is against user experience UX best practice to use BLOB and CLOB data types in string and retrieving binary data from an SQL database thus it is advised that you use the technique that involves storing the URL for the image( or any Binary file in the database). This URL will help the user application to retrieve and use this binary file.

2. Second the BLOB and CLOB data types are only available to a number of SQL versions thus functions such as LOAD_FILE or the datatypes themselves could miss in some versions.

3. Third DON'T USE BLOB OR CLOB. Store the URL; let the user application access the binary file from a folder in the project directory.

You could try using something like HTML Tidy to cleanup any "broken" HTML and convert the HTML to XHTML, which you can then parse with a XML parser.

I got it working by using Jimmy Zoto's answer and adding a second parameter to my belongsTo. Here it is:

First, as suggested by Jimmy Zoto, my code in blade from

$article->poster->name 

to

$article->poster['name']

Next is to add a second parameter in my belongsTo, from

return $this->belongsTo('App\User');

to

return $this->belongsTo('App\User', 'user_id');

in which user_id is my foreign key in the news table.

You could use the printf(1) command, e.g. like

printf "Hello times %d\nHere\n" $[2+3] 

The  printf command may accept arguments and needs a format control string similar (but not exactly the same) to the one for the standard C printf(3) function...

Have you tried the Text property? It works for me.

ComboBox1.Text = "test1";

The SelectedText property is for the selected portion of the editable text in the textbox part of the combo box.

You can use this option provided by dataTable itself using buttons.

dom: 'Bfrtip',
 buttons: [
      'selectAll',
      'selectNone'
 ]'

Here is a sample code

var tableFaculty = $('#tableFaculty').DataTable({
    "columns": [
        {
            data: function (row, type, set) {
                return '';
            }
        },
        {data: "NAME"}
    ],
    "columnDefs": [
        {
            orderable: false,
            className: 'select-checkbox',
            targets: 0
        }
    ],
    select: {
        style: 'multi',
        selector: 'td:first-child'
    },
    dom: 'Bfrtip',
    buttons: [
        'selectAll',
        'selectNone'
    ],
    "order": [[0, 'desc']]
});

For Hibernate you can use the jackson-datatype-hibernate project to accommodate JSON serialization/deserialization with lazy-loaded objects.

For example,

import com.fasterxml.jackson.databind.Module;
import com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JacksonDatatypeHibernate5Configuration {

    // Register Jackson Hibernate5 Module to handle JSON serialization of lazy-loaded entities
    // Any beans of type com.fasterxml.jackson.databind.Module are automatically
    // registered with the auto-configured Jackson2ObjectMapperBuilder
    // https://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html#howto-customize-the-jackson-objectmapper
    @Bean
    public Module hibernate5Module() {
        Hibernate5Module hibernate5Module = new Hibernate5Module();
        hibernate5Module.enable( Hibernate5Module.Feature.FORCE_LAZY_LOADING );
        hibernate5Module.disable( Hibernate5Module.Feature.USE_TRANSIENT_ANNOTATION );
        return hibernate5Module;
    }
}

I encountered the same problem in child components where initially it would have to have the current value of the Subject, then subscribe to the Subject to listen to changes. I just maintain the current value in the Service so it is available for components to access, e.g. :

import {Storage} from './storage';
import {Injectable} from 'angular2/core';
import {Subject}    from 'rxjs/Subject';

@Injectable()
export class SessionStorage extends Storage {

  isLoggedIn: boolean;

  private _isLoggedInSource = new Subject<boolean>();
  isLoggedIn = this._isLoggedInSource.asObservable();
  constructor() {
    super('session');
    this.currIsLoggedIn = false;
  }
  setIsLoggedIn(value: boolean) {
    this.setItem('_isLoggedIn', value, () => {
      this._isLoggedInSource.next(value);
    });
    this.isLoggedIn = value;
  }
}

A component that needs the current value could just then access it from the service, i.e,:

sessionStorage.isLoggedIn

Not sure if this is the right practice :)

Shorter answer: no, you must encode a space; it is correct to encode a space as +, but only in the query string; in the path you must use %20.

If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.

Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.

If you want to audit a client application name along with each failed login, you can use an Extended Events session.

To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/

With C++11 the answer to this question has now changed and you can in fact do:

struct a {
    const int b[2];
    // other bits follow

    // and here's the constructor
    a();
};

a::a() :
    b{2,3}
{
     // other constructor work
}

int main() {
 a a;
}

No, there is no such printf width specifier to print floating-point with maximum precision. Let me explain why.

The maximum precision of float and double is variable, and dependent on the actual value of the float or double.

Recall float and double are stored in sign.exponent.mantissa format. This means that there are many more bits used for the fractional component for small numbers than for big numbers.

For example, float can easily distinguish between 0.0 and 0.1.

float r = 0;
printf( "%.6f\n", r ) ; // 0.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // 0.100000

But float has no idea of the difference between 1e27 and 1e27 + 0.1.

r = 1e27;
printf( "%.6f\n", r ) ; // 999999988484154753734934528.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // still 999999988484154753734934528.000000

This is because all the precision (which is limited by the number of mantissa bits) is used up for the large part of the number, left of the decimal.

The %.f modifier just says how many decimal values you want to print from the float number as far as formatting goes. The fact that the accuracy available depends on the size of the number is up to you as the programmer to handle. printf can't/doesn't handle that for you.

LocalDate ld ....;
LocalDateTime ldtime ...;

ld.isEqual(LocalDate.from(ldtime));

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

I know it's an old question, but if someone is looking here again... see https://python-sounddevice.readthedocs.io/en/0.4.1/index.html .

It has a nice example "Input to Ouput Pass-Through" here https://python-sounddevice.readthedocs.io/en/0.4.1/examples.html#input-to-output-pass-through .

... and a lot of other examples as well ...

    // this will give all the forms on the page.

    $('form')

   // If you know the name of form then.

    $('form[name="myFormName"]')

  //  If you don't know know the name but the position (starts with 0)

    $('form:eq(1)')  // 2nd form will be fetched.

Every 5-10 minutes my application pool kept crashing with this exit code. I do not want to ruin your trust of the Garbage Collector, but the following solution worked for me.

I added a Job that calls GC.GetTotalMemory(true) every minute.

I suppose that, for some reason, the GC is not automatically inspecting the memory often enough for the high number of disposable objects that I use.

With modern browser i prefer a much lightweight approach with a bit of Js and CSS3...

    </system.web>
</configuration>

Relative answer: Deploying website: 500 - Internal server error

By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.

Use the Set#toArray(IntFunction<T[]>) method taking an IntFunction as generator.

String[] GPXFILES1 = myset.toArray(String[]::new);

If you're not on Java 11 yet, then use the Set#toArray(T[]) method taking a typed array argument of the same size.

String[] GPXFILES1 = myset.toArray(new String[myset.size()]);

While still not on Java 11, and you can't guarantee that myset is unmodifiable at the moment of conversion to array, then better specify an empty typed array.

String[] GPXFILES1 = myset.toArray(new String[0]);

Here is what is going on.

First, the only global variables Python really has are module-scoped variables. You cannot make a variable that is truly global; all you can do is make a variable in a particular scope. (If you make a variable inside the Python interpreter, and then import other modules, your variable is in the outermost scope and thus global within your Python session.)

All you have to do to make a module-global variable is just assign to a name.

Imagine a file called foo.py, containing this single line:

X = 1

Now imagine you import it.

import foo
print(foo.X)  # prints 1

However, let's suppose you want to use one of your module-scope variables as a global inside a function, as in your example. Python's default is to assume that function variables are local. You simply add a global declaration in your function, before you try to use the global.

def initDB(name):
    global __DBNAME__  # add this line!
    if __DBNAME__ is None: # see notes below; explicit test for None
        __DBNAME__ = name
    else:
        raise RuntimeError("Database name has already been set.")

By the way, for this example, the simple if not __DBNAME__ test is adequate, because any string value other than an empty string will evaluate true, so any actual database name will evaluate true. But for variables that might contain a number value that might be 0, you can't just say if not variablename; in that case, you should explicitly test for None using the is operator. I modified the example to add an explicit None test. The explicit test for None is never wrong, so I default to using it.

Finally, as others have noted on this page, two leading underscores signals to Python that you want the variable to be "private" to the module. If you ever do an import * from mymodule, Python will not import names with two leading underscores into your name space. But if you just do a simple import mymodule and then say dir(mymodule) you will see the "private" variables in the list, and if you explicitly refer to mymodule.__DBNAME__ Python won't care, it will just let you refer to it. The double leading underscores are a major clue to users of your module that you don't want them rebinding that name to some value of their own.

It is considered best practice in Python not to do import *, but to minimize the coupling and maximize explicitness by either using mymodule.something or by explicitly doing an import like from mymodule import something.

EDIT: If, for some reason, you need to do something like this in a very old version of Python that doesn't have the global keyword, there is an easy workaround. Instead of setting a module global variable directly, use a mutable type at the module global level, and store your values inside it.

In your functions, the global variable name will be read-only; you won't be able to rebind the actual global variable name. (If you assign to that variable name inside your function it will only affect the local variable name inside the function.) But you can use that local variable name to access the actual global object, and store data inside it.

You can use a list but your code will be ugly:

__DBNAME__ = [None] # use length-1 list as a mutable

# later, in code:  
if __DBNAME__[0] is None:
    __DBNAME__[0] = name

A dict is better. But the most convenient is a class instance, and you can just use a trivial class:

class Box:
    pass

__m = Box()  # m will contain all module-level values
__m.dbname = None  # database name global in module

# later, in code:
if __m.dbname is None:
    __m.dbname = name

(You don't really need to capitalize the database name variable.)

I like the syntactic sugar of just using __m.dbname rather than __m["DBNAME"]; it seems the most convenient solution in my opinion. But the dict solution works fine also.

With a dict you can use any hashable value as a key, but when you are happy with names that are valid identifiers, you can use a trivial class like Box in the above.

If you want to keep the changes and change the branch in a single line command

git stash && git checkout <branch_name> && git stash pop

$('form#register input[required]')

It will only return inputs which have required attribute.

Yes we have done this.

In your Index.cshtml you'll have something like..

<div id='gameModal' class='modal hide fade in' data-url='@Url.Action("GetGameListing")'>
   <div id='gameContainer'>
   </div>
</div>

<button id='showGame'>Show Game Listing</button>

Then in JS for the same page (inlined or in a separate file you'll have something like this..

$(document).ready(function() {
   $('#showGame').click(function() {
        var url = $('#gameModal').data('url');

        $.get(url, function(data) {
            $('#gameContainer').html(data);

            $('#gameModal').modal('show');
        });
   });
});

With a method on your controller that looks like this..

[HttpGet]
public ActionResult GetGameListing()
{
   var model = // do whatever you need to get your model
   return PartialView(model);
}

You will of course need a view called GetGameListing.cshtml inside of your Views folder..

The build-in raw_input should help.

for i in range(3):
    print ("So much work to do!")
k = raw_input("Press any key to continue...")
print ("Ok, back to work.")

1. Use the 'jet' colormap for a transition between blue and red.

I faced this challenge with select2. It go resolved after I downloaded the latest version of the library and replaced the one (the css and js files) in my project.

You would need to enclose the pattern in a delimiter - typically a slash (/) is used. Try this:

echo preg_replace("/[^0-9]/","",'604-619-5135');

A global JS variable (object) can be used to pass data between components. Example: Passing data from Ammlogin.vue to Options.vue. In Ammlogin.vue rspData is set to the response from the server. In Options.vue the response from the server is made available via rspData.

index.html:

<script>
    var rspData; // global - transfer data between components
</script>

Ammlogin.vue:

....    
export default {
data: function() {return vueData}, 
methods: {
    login: function(event){
        event.preventDefault(); // otherwise the page is submitted...
        vueData.errortxt = "";
        axios.post('http://vueamm...../actions.php', { action: this.$data.action, user: this.$data.user, password: this.$data.password})
            .then(function (response) {
                vueData.user = '';
                vueData.password = '';
                // activate v-link via JS click...
                // JSON.parse is not needed because it is already an object
                if (response.data.result === "ok") {
                    rspData = response.data; // set global rspData
                    document.getElementById("loginid").click();
                } else {
                    vueData.errortxt = "Felaktig avändare eller lösenord!"
                }

Why be easy when it can be complicated? Why use third-party applications like netdom.exe when correct interogations is the way? Try 2 interogations:

wmic computersystem where caption='%computername%' get caption, UserName, Domain /format:value

wmic computersystem where "caption like '%%%computername%%%'" get caption, UserName, Domain /format:value

or in a batch file use loop

for /f "tokens=2 delims==" %%i in ('wmic computersystem where "Caption like '%%%currentname%%%'" get UserName /format:value') do (echo. UserName- %%i)

A 32-bit unsigned int has a range from 0 to 4,294,967,295. 0 to 65535 would be a 16-bit unsigned.

An unsigned long long (and, on a 64-bit implementation, possibly also ulong and possibly uint as well) have a range (at least) from 0 to 18,446,744,073,709,551,615 (2⁶⁴-1). In theory it could be greater than that, but at least for now that's rare to nonexistent.

I actually had a failure in the Microsoft uninstall. I had installed node-v8.2.1-x64 and needed to run version node-v6.11.1-x64.

The uninstalled was failing with the error: "Windows cannot access the specified device, path, or file" or similar.

I ended up going to the Downloads folder right clicking the node-v8.2.1-x64 MSI and selecting uninstall.. this worked.

Call .get() at the very end to turn the resulting jQuery object into a true array.

$("#merge_button").click(function(event){
    event.preventDefault();
    var searchIDs = $("#find-table input:checkbox:checked").map(function(){
      return $(this).val();
    }).get(); // <----
    console.log(searchIDs);
});

Per the documentation:

As the return value is a jQuery object, which contains an array, it's very common to call .get() on the result to work with a basic array.

$ echo | mutt -a syslogs.tar.gz [email protected]

But it uses mutt, not mail (or mailx).

I assume you mean list and not array? There is such a thing as an array in Python, but more often than not you want a list instead of an array.

The way to check if a list contains a value is to use in:

if paid[j] in d:
    # ...

 <%if (System.Configuration.ConfigurationManager.AppSettings["OperationalMode"] != "live") {%>
                        &nbsp;[<%=System.Environment.MachineName%>]
                        <%}%>

Please try the below code for repeated fade-out/fade-in animation

AlphaAnimation anim = new AlphaAnimation(1.0f, 0.3f);
    anim.setRepeatCount(Animation.INFINITE);
    anim.setRepeatMode(Animation.REVERSE);
    anim.setDuration(300);
view.setAnimation(anim); // to start animation
view.setAnimation(null); // to stop animation

Generally speaking, using setState inside useEffect will create an infinite loop that most likely you don't want to cause. There are a couple of exceptions to that rule which I will get into later.

useEffect is called after each render and when setState is used inside of it, it will cause the component to re-render which will call useEffect and so on and so on.

One of the popular cases that using useState inside of useEffect will not cause an infinite loop is when you pass an empty array as a second argument to useEffect like useEffect(() => {....}, []) which means that the effect function should be called once: after the first mount/render only. This is used widely when you're doing data fetching in a component and you want to save the request data in the component's state.

It's modern, it's fast, it's simple. I use it for every new project. I prefer it a lot over C3P0, don't know the other pools too well.

While the idea behind LINQ syntax is to emulate the SQL syntax, you shouldn't always think of directly translating your SQL code into LINQ. In this particular case, we don't need to do group into since join into is a group join itself.

Here's my solution:

from p in context.ParentTable
join c in context.ChildTable on p.ParentId equals c.ChildParentId into joined
select new { ParentId = p.ParentId, Count = joined.Count() }

Unlike the mostly voted solution here, we don't need j1, j2 and null checking in Count(t => t.ChildId != null)

try this

if(!isset($_SESSION)){ 
    session_start();
}

I suggest you to use ob_start(); before starting any sesson varriable, this should order you browser buffer.

edit: Added an extra ) after $_SESSION

Unfortunately the size attribute will not work very well. There will be extra space and too little space sometimes, depending on how the font is set up. (check out the example)

If you want this to work well, try watching for changes on the input, and resize it then. You probably want to set it to the input's scrollWidth. We would need to account for box sizing, too.

In the following example, I'm setting the size of the input to 1 to prevent it from having a scrollWidth that is greater than our initial width (set manually with CSS).

I think this should work in even IE6, but don't take my word for it.

Depending on your use case, you may need to bind the adjust function to other events. E.g. changing an input's value programmatically, or changing the element's style's display property from none (where scrollWidth === 0) to block or inline-block, etc.

To do this in t-sql, you can use the following system stored procedures to schedule a daily job. This example schedules daily at 1:00 AM. See Microsoft help for details on syntax of the individual stored procedures and valid range of parameters.

The data type TEXT is old and should not be used anymore, it is a pain to select data out of a TEXT column.

ntext, text, and image (Transact-SQL)

ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

you need to use TEXTPTR (Transact-SQL) to retrieve the text data.

Also see this article on Handling The Text Data Type.

I tried using the dtypes=[datetime, ...] option, but

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

I encountered the following error:

TypeError: data type not understood

The only change I had to make is to replace datetime with datetime.datetime

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime.datetime, datetime.datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

you need to put font-awesome file in css folder and change

href="../css/font-awesome.css" to href="css/font-awesome.css"

One more thing You can Replace this Font-awesome css File And and try this one

By experiment I was able to observe this:

When SQL Profiler 2005 or SQL Profiler 2000 is used with database residing in SQLServer 2000 - problem mentioned problem persists, but when SQL Profiler 2005 is used with SQLServer 2005 database, it works perfect!

In Summary, the issue seems to be prevalent in SQLServer 2000 & rectified in SQLServer 2005.

The solution for the issue when dealing with SQLServer 2000 is (as explained by wearejimbo)

1. Identify the DatabaseID of the database you want to filter by querying the sysdatabases table as below

   SELECT * 
   FROM master..sysdatabases 
   WHERE name like '%your_db_name%'   -- Remove this line to see all databases
   ORDER BY dbid
   

2. Use the DatabaseID Filter (instead of DatabaseName) in the New Trace window of SQL Profiler 2000

This query run for me ( for MySQL). mytable_backup must be present before this query run.

insert into mytable_backup select * from mytable

change svg to match your element

function svg2img(){
    var svg = document.querySelector('svg');
    var xml = new XMLSerializer().serializeToString(svg);
    var svg64 = btoa(xml); //for utf8: btoa(unescape(encodeURIComponent(xml)))
    var b64start = 'data:image/svg+xml;base64,';
    var image64 = b64start + svg64;
    return image64;
};svg2img()

If you have a container and two sub containers, you can do like this

jQuery

    $("#previousbutton").click(function() {
    $("#form_sub_container1").show();
    $("#form_sub_container2").hide(); })

    $("#nextbutton").click(function() {
    $("#form_container").find(":hidden").show().next();
    $("#form_sub_container1").hide();
})

HTML

     <div id="form_container">
            <div id="form_sub_container1" style="display: block;">
            </div>

            <div id="form_sub_container2" style="display: none;">
            </div>
     </div>

Removing IISExpress and vs directories and using ssl port range of 44300 to 44399 (inclusive) from this article worked for me

Task are being executed on the ThreadPool (at least, if you are using the default factory), so aborting the thread cannot affect the tasks. For aborting tasks, see Task Cancellation on msdn.

If you're not restricted to JQuery, you can use the prototype.js framework. It has a class called Hash: You can even use JQuery & prototype.js together. Just type jQuery.noConflict();

var h = new Hash();
h.set("key", "value");
h.get("key");
h.keys(); // returns an array of keys
h.values(); // returns an array of values

Following worked for me and it seems very simple as well:

Let's assume that we want to import a script ./data/get_my_file.py and want to access get_set1() function in it.

import sys
sys.path.insert(0, './data/')
import get_my_file as db

print (db.get_set1())

<section ng-controller="testController as ctrl" class="test_cls"  data-ng-init="fn_load()">

$scope.fn_load = function () {
  console.log("page load")
};

Faced this exact issue. The problem resolved when i changed the Service="Namespace.ServiceName" tag in the Markup (right click xxxx.svc and select View Markup in visual studio) to match the namespace i used for my xxxx.svc.cs file

I'm a proponent of not assuming the best solution and testing it. Below are some modifications I did to create simple classes of examples by both @igor-chubin and @user448810. First off let me say it's all great information, thank you guys. But I have to acknowledge @user448810 for his clever solution, which turns out to be the fastest by far (of those I tested). So kudos to you, sir! In all examples I use a values of 1 million (1,000,000) as n.

Please feel free to try the code out.

Good luck!

Method 1 as described by Igor Chubin:

def primes_method1(n):
    out = list()
    for num in range(1, n+1):
        prime = True
        for i in range(2, num):
            if (num % i == 0):
                prime = False
        if prime:
            out.append(num)
    return out

Benchmark: Over 272+ seconds

Method 2 as described by Igor Chubin:

def primes_method2(n):
    out = list()
    for num in range(1, n+1):
        if all(num % i != 0 for i in range(2, num)):
            out.append(num)
    return out

Benchmark: 73.3420000076 seconds

Method 3 as described by Igor Chubin:

def primes_method3(n):
    out = list()
    for num in range(1, n+1):
        if all(num % i != 0 for i in range(2, int(num**.5 ) + 1)):
            out.append(num)
    return out

Benchmark: 11.3580000401 seconds

Method 4 as described by Igor Chubin:

def primes_method4(n):
    out = list()
    out.append(2)
    for num in range(3, n+1, 2):
        if all(num % i != 0 for i in range(2, int(num**.5 ) + 1)):
            out.append(num)
    return out

Benchmark: 8.7009999752 seconds

Method 5 as described by user448810 (which I thought was quite clever):

def primes_method5(n):
    out = list()
    sieve = [True] * (n+1)
    for p in range(2, n+1):
        if (sieve[p]):
            out.append(p)
            for i in range(p, n+1, p):
                sieve[i] = False
    return out

Benchmark: 1.12000012398 seconds

Notes: Solution 5 listed above (as proposed by user448810) turned out to be the fastest and honestly quiet creative and clever. I love it. Thanks guys!!

EDIT: Oh, and by the way, I didn't feel there was any need to import the math library for the square root of a value as the equivalent is just (n**.5). Otherwise I didn't edit much other then make the values get stored in and output array to be returned by the class. Also, it would probably be a bit more efficient to store the results to a file than verbose and could save a lot on memory if it was just one at a time but would cost a little bit more time due to disk writes. I think there is always room for improvement though. So hopefully the code makes sense guys.

2021 EDIT: I know it's been a really long time but I was going back through my Stackoverflow after linking it to my Codewars account and saw my recently accumulated points, which which was linked to this post. Something I read in the original poster caught my eye for @user448810, so I decided to do a slight modification mentioned in the original post by filtering out odd values before appending the output array. The results was much better performance for both the optimization as well as latest version of Python 3.8 with a result of 0.723 seconds (prior code) vs 0.504 seconds using 1,000,000 for n.

def primes_method5(n):
    out = list()
    sieve = [True] * (n+1)
    for p in range(2, n+1):
        if (sieve[p] and sieve[p]%2==1):
            out.append(p)
            for i in range(p, n+1, p):
                sieve[i] = False
    return out

Nearly five years later, I might know a bit more but I still just love Python, and it's kind of crazy to think it's been that long. The post honestly feels like it was made a short time ago and at the time I had only been using python about a year I think. And it still seems relevant. Crazy. Good times.

You can set the connection timeout to the connection level and command level.

Add "Connection Timeout=10" to the connection string. Now connection timeout is 10 seconds.

var connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;Connection Timeout=10";
using (var con = new SqlConnection(connectionString))
{

}

Set the of CommandTimeout property to SqlCommand

var connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword";
using (var con = new SqlConnection(connectionString))
{

    using (var cmd =new SqlCommand())
    {
        cmd.CommandTimeout = 10;
    }

}

You can iterate through the <li>s in the <ul> and stop when you find the right one.

function getIndex(li) {
    var lis = li.parentNode.getElementsByTagName('li');
    for (var i = 0, len = lis.length; i < len; i++) {
        if (li === lis[i]) {
            return i;
        }
    }

}

In my case, the problem was setting the variable of the Execute SQL Task, in parameters mapping the parameter name, (in OLEDB must be the position of the parameter that you call in the stored procedure), I had 1, but the first parameter starts in 0, so I changed it and voilá!

If you use a current version of m2eclipse (which you should if you use eclipse and maven):

Select the menu entry

Navigate -> Open Maven POM

and enter the artifact you are looking for.

The pom will open in the pom editor, from which you can select the tab Dependency Hierarchy to view the dependency hierarchy (as the name suggests :-) )

Recent updates enabled computers with AMD processors to run Android Emulator and you don't need to install ARM images anymore. Taken from the Android Developers blog:

If you have an AMD processor in your computer you need the following setup requirements to be in place:

• AMD Processor - Recommended: AMD® Ryzen™ processors
  
• Android Studio 3.2 Beta or higher
  
• Android Emulator v27.3.8+
  
• x86 Android Virtual Device (AVD)
  
• Windows 10 with April 2018 Update
  
• Enable via Windows Features: "Windows Hypervisor Platform"
  

The important point is enabling Windows Hypervisor Platform and that's it! I strongly recommend reading the whole blog post:
https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html

You can remove the hover state by temporarily removing the link from the DOM. See http://testbug.handcraft.com/ipad.html

In the CSS you have:

:hover {background:red;}

In the JS you have:

function fix()
{
    var el = this;
    var par = el.parentNode;
    var next = el.nextSibling;
    par.removeChild(el);
    setTimeout(function() {par.insertBefore(el, next);}, 0)
}

And then in your HTML you have:

<a href="#" ontouchend="this.onclick=fix">test</a>

The problem seems to be happening when your target sdk is 28. So after trying out many options finally this worked.

<activity
            android:name=".activities.FilterActivity"
            android:theme="@style/Transparent"
            android:windowSoftInputMode="stateHidden|adjustResize" />

style:-

<style name="Transparent" parent="Theme.AppCompat.Light.NoActionBar">
     <item name="android:windowIsTranslucent">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
     <item name="android:windowIsFloating">true</item>
     <item name="android:windowContentOverlay">@null</item>
     <item name="android:windowNoTitle">true</item>
     <item name="android:backgroundDimEnabled">false</item>
 </style>

Note:parent="Theme.AppCompat.Light.NoActionBar" is needed for api 28. Previously had something else at api 26. Was working great but started to give problem at 28. Hope it helps someone out here. EDIT: For some only by setting <item name="android:windowIsTranslucent">false</item> and <item name="android:windowIsFloating">false</item> worked.May be depends upon the way you implement the solution works.In my case it worked by setting them to true.

i wanted to mention Jailbreak specifically (GitHub):

Jailbreak

Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.

Prerequisites: Win32

There are MANY reasons to use brace initialization, but you should be aware that the initializer_list<> constructor is preferred to the other constructors, the exception being the default-constructor. This leads to problems with constructors and templates where the type T constructor can be either an initializer list or a plain old ctor.

struct Foo {
    Foo() {}

    Foo(std::initializer_list<Foo>) {
        std::cout << "initializer list" << std::endl;
    }

    Foo(const Foo&) {
        std::cout << "copy ctor" << std::endl;
    }
};

int main() {
    Foo a;
    Foo b(a); // copy ctor
    Foo c{a}; // copy ctor (init. list element) + initializer list!!!
}

Assuming you don't encounter such classes there is little reason not to use the intializer list.

Another approach!

string str = "12345";
bool containsOnlyDigits = true;
try { if(Convert.ToInt32(str) < 0){ containsOnlyDigits = false; } }
catch { containsOnlyDigits = false; }

Here, if the statement Convert.ToInt32(str) fails, then string does not contain digits only. Another possibility is that if the string has "-12345" which gets converted to -12345 successfully, then there is a check for verifying that the number converted is not less than zero.

You can use a combiation of LEFT and CHARINDEX to find the index of the first space, and then grab everything to the left of that.

 SELECT LEFT(YourColumn, charindex(' ', YourColumn) - 1) 

And in case any of your columns don't have a space in them:

SELECT LEFT(YourColumn, CASE WHEN charindex(' ', YourColumn) = 0 THEN 
    LEN(YourColumn) ELSE charindex(' ', YourColumn) - 1 END)

map can be much faster than replace

If your dictionary has more than a couple of keys, using map can be much faster than replace. There are two versions of this approach, depending on whether your dictionary exhaustively maps all possible values (and also whether you want non-matches to keep their values or be converted to NaNs):

Exhaustive Mapping

In this case, the form is very simple:

df['col1'].map(di)       # note: if the dictionary does not exhaustively map all
                         # entries then non-matched entries are changed to NaNs

Although map most commonly takes a function as its argument, it can alternatively take a dictionary or series: Documentation for Pandas.series.map

Non-Exhaustive Mapping

If you have a non-exhaustive mapping and wish to retain the existing variables for non-matches, you can add fillna:

df['col1'].map(di).fillna(df['col1'])

as in @jpp's answer here: Replace values in a pandas series via dictionary efficiently

Benchmarks

Using the following data with pandas version 0.23.1:

di = {1: "A", 2: "B", 3: "C", 4: "D", 5: "E", 6: "F", 7: "G", 8: "H" }
df = pd.DataFrame({ 'col1': np.random.choice( range(1,9), 100000 ) })

and testing with %timeit, it appears that map is approximately 10x faster than replace.

Note that your speedup with map will vary with your data. The largest speedup appears to be with large dictionaries and exhaustive replaces. See @jpp answer (linked above) for more extensive benchmarks and discussion.

An old thread, but it may help someone like me. I resolved the issue by setting up SMTP server value to a legitimate value in PHP.ini

Starting with 1.6.4, Arduino IDE can be used to program and upload the NodeMCU board by installing the ESP8266 third-party platform package (refer https://github.com/esp8266/Arduino):

• Start Arduino, go to File > Preferences
• Add the following link to the Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json and press OK button
• Click Tools > Boards menu > Boards Manager, search for ESP8266 and install ESP8266 platform from ESP8266 community (and don't forget to select your ESP8266 boards from Tools > Boards menu after installation)

To install additional ESP8266WiFi library:

• Click Sketch > Include Library > Manage Libraries, search for ESP8266WiFi and then install with the latest version.

After above steps, you should compile the sketch normally.

There is no portable way to get resolution of less than a second in standard C So best you can do is, use the POSIX function gettimeofday().

Yes, there's str_to_date

i have tried this one and it worked for me. hope it works for others too.

1. Open build.gradle module file
2. downgrade you sdkversion from 25 to 24 or 23
3. add 'multiDexEnabled true'
4. comment this line : compile 'com.android.support:appcompat-v7:25.1.0' (if it's in 'dependencies')
5. Sync your project and ready to go.

Here i have attached screenshot to explain things. Go through this steps

happy to help.

thanks.

As many here have already mentioned, I also prefer using .hpp for header-only libraries that use template classes/functions. I prefer to use .h for header files accompanied by .cpp source files or shared or static libraries.

Most of the libraries I develop are template based and thus need to be header only, but when writing applications I tend to separate declaration from implementation and end up with .h and .cpp files

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

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

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

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

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

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

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

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

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

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

BEWARE:

enum Example
{
    One = 1,
    Two = 2,
    Three = 3
}

Enum.(Try)Parse() accepts multiple, comma-separated arguments, and combines them with binary 'or' |. You cannot disable this and in my opinion you almost never want it.

var x = Enum.Parse("One,Two"); // x is now Three

Even if Three was not defined, x would still get int value 3. That's even worse: Enum.Parse() can give you a value that is not even defined for the enum!

I would not want to experience the consequences of users, willingly or unwillingly, triggering this behavior.

Additionally, as mentioned by others, performance is less than ideal for large enums, namely linear in the number of possible values.

I suggest the following:

    public static bool TryParse<T>(string value, out T result)
        where T : struct
    {
        var cacheKey = "Enum_" + typeof(T).FullName;

        // [Use MemoryCache to retrieve or create&store a dictionary for this enum, permanently or temporarily.
        // [Implementation off-topic.]
        var enumDictionary = CacheHelper.GetCacheItem(cacheKey, CreateEnumDictionary<T>, EnumCacheExpiration);

        return enumDictionary.TryGetValue(value.Trim(), out result);
    }

    private static Dictionary<string, T> CreateEnumDictionary<T>()
    {
        return Enum.GetValues(typeof(T))
            .Cast<T>()
            .ToDictionary(value => value.ToString(), value => value, StringComparer.OrdinalIgnoreCase);
    }

This may or may not be a sub-optimal way of doing things, but the simplest solution to the multi-page problem I found was to ensure all rendering is done before calling the jsPDFObj.save method.

As for rendering hidden articles, this is solved with a similar fix to css image text replacement, I position absolutely the element to be rendered -9999px off the page left, this doesn't affect layout and allows for the elem to be visible to html2pdf, especially when using tabs, accordions and other UI components that depend on {display: none}.

This method wraps the prerequisites in a promise and calls pdf.save() in the finally() method. I cannot be sure that this is foolproof, or an anti-pattern, but it would seem that it works in most cases I have thrown at it.

// Get List of paged elements._x000D_
let elems = document.querySelectorAll('.elemClass');_x000D_
let pdf = new jsPDF("portrait", "mm", "a4");_x000D_
_x000D_
// Fix Graphics Output by scaling PDF and html2canvas output to 2_x000D_
pdf.scaleFactor = 2;_x000D_
_x000D_
// Create a new promise with the loop body_x000D_
let addPages = new Promise((resolve,reject)=>{_x000D_
  elems.forEach((elem, idx) => {_x000D_
    // Scaling fix set scale to 2_x000D_
    html2canvas(elem, {scale: "2"})_x000D_
      .then(canvas =>{_x000D_
        if(idx < elems.length - 1){_x000D_
          pdf.addImage(canvas.toDataURL("image/png"), 0, 0, 210, 297);_x000D_
          pdf.addPage();_x000D_
        } else {_x000D_
          pdf.addImage(canvas.toDataURL("image/png"), 0, 0, 210, 297);_x000D_
          console.log("Reached last page, completing");_x000D_
        }_x000D_
  })_x000D_
  _x000D_
  setTimeout(resolve, 100, "Timeout adding page #" + idx);_x000D_
})_x000D_
_x000D_
addPages.finally(()=>{_x000D_
   console.log("Saving PDF");_x000D_
   pdf.save();_x000D_
});

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

I was facing the same problem trying to truncate a VARCHAR from 32 to 8 and getting the ERROR: value too long for type character varying(8). I want to stay as close to SQL as possible because I'm using a self-made JPA-like structure that we might have to switch to different DBMS according to customer's choices (PostgreSQL being the default one). Hence, I don't want to use the trick of altering System tables.

I ended using the USING statement in the ALTER TABLE:

ALTER TABLE "MY_TABLE" ALTER COLUMN "MyColumn" TYPE varchar(8)
USING substr("MyColumn", 1, 8)

As @raylu noted, ALTER acquires an exclusive lock on the table so all other operations will be delayed until it completes.

We can use the formula method of aggregate. The variables on the 'rhs' of ~ are the grouping variables while the . represents all other variables in the 'df1' (from the example, we assume that we need the mean for all the columns except the grouping), specify the dataset and the function (mean).

aggregate(.~id1+id2, df1, mean)

Or we can use summarise_each from dplyr after grouping (group_by)

library(dplyr)
df1 %>%
    group_by(id1, id2) %>% 
    summarise_each(funs(mean))

Or using summarise with across (dplyr devel version - ‘0.8.99.9000’)

df1 %>% 
    group_by(id1, id2) %>%
    summarise(across(starts_with('val'), mean))

Or another option is data.table. We convert the 'data.frame' to 'data.table' (setDT(df1), grouped by 'id1' and 'id2', we loop through the subset of data.table (.SD) and get the mean.

library(data.table)
setDT(df1)[, lapply(.SD, mean), by = .(id1, id2)] 

data

df1 <- structure(list(id1 = c("a", "a", "a", "a", "b", "b", 
"b", "b"
), id2 = c("x", "x", "y", "y", "x", "y", "x", "y"), 
val1 = c(1L, 
2L, 3L, 4L, 1L, 4L, 3L, 2L), val2 = c(9L, 4L, 5L, 9L, 7L, 4L, 
9L, 8L)), .Names = c("id1", "id2", "val1", "val2"), 
class = "data.frame", row.names = c("1", 
"2", "3", "4", "5", "6", "7", "8"))

I just found the answer from a forum referred by one of my colleague. If you declare a variable outside a function, it's always global. No matter if you use var keyword or not. But, if you declare the variable inside a function, it has a big difference. Inside a function, if you declare the variable using var keyword, it will be local, but if you declare the variable without var keyword, it will be global. It can overwrite your previously declared variables. - See more at: http://forum.webdeveloperszone.com/question/what-is-the-difference-between-using-var-keyword-or-not-using-var-during-variable-declaration/#sthash.xNnLrwc3.dpuf

In order to completely set the background to a given color :

1) set first the background color

2) call method "Clear(0,0,this.getWidth(),this.getHeight())" (width and height of the component paint area)

I think it is the basic procedure to set the background... I've had the same problem.

Another usefull hint : if you want to draw BUT NOT in a specific zone (something like a mask or a "hole"), call the setClip() method of the graphics with the "hole" shape (any shape) and then call the Clear() method (background should previously be set to the "hole" color).

You can make more complicated clip zones by calling method clip() (any times you want) AFTER calling method setClip() to have intersections of clipping shapes.

I didn't find any method for unions or inversions of clip zones, only intersections, too bad...

Hope it helps

TL;DR:

No, don't subscribe manually to them, don't use them in services. Use them as is shown in the documentation only to emit events in components. Don't defeat angular's abstraction.

Answer:

No, you should not subscribe manually to it.

EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald

[...] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.

This is stated really clear in EventEmitter's documentation.

Use by directives and components to emit custom Events.

What's wrong about using it?

Angular2 will never guarantee us that EventEmitter will continue being an Observable. So that means refactoring our code if it changes. The only API we must access is its emit() method. We should never subscribe manually to an EventEmitter.

All the stated above is more clear in this Ward Bell's comment (recommended to read the article, and the answer to that comment). Quoting for reference

Do NOT count on EventEmitter continuing to be an Observable!

Do NOT count on those Observable operators being there in the future!

These will be deprecated soon and probably removed before release.

Use EventEmitter only for event binding between a child and parent component. Do not subscribe to it. Do not call any of those methods. Only call eve.emit()

His comment is in line with Rob's comment long time ago.

So, how to use it properly?

Simply use it to emit events from your component. Take a look a the following example.

@Component({
    selector : 'child',
    template : `
        <button (click)="sendNotification()">Notify my parent!</button>
    `
})
class Child {
    @Output() notifyParent: EventEmitter<any> = new EventEmitter();
    sendNotification() {
        this.notifyParent.emit('Some value to send to the parent');
    }
}

@Component({
    selector : 'parent',
    template : `
        <child (notifyParent)="getNotification($event)"></child>
    `
})
class Parent {
    getNotification(evt) {
        // Do something with the notification (evt) sent by the child!
    }
}

How not to use it?

class MyService {
    @Output() myServiceEvent : EventEmitter<any> = new EventEmitter();
}

Stop right there... you're already wrong...

Hopefully these two simple examples will clarify EventEmitter's proper usage.

Sorry, but there's to much coding going on here ...

I'll give the simplest one to you for free. I invented it back in 2005, although the javascript source now says it was their staff who came up with it - more than a year later!

Anyway, here it is, no javascript !!!

<!-- Paste this code into the BODY section of your HTML document  -->
<select size="1" name="jumpit" onchange="document.location.href=this.value"> 
<option selected value="">Make a Selection</option>
<option value="http://www.javascriptsource.com/">The JavaScript Source</option>
<option value="http://www.javascript.com">JavaScript.com</option>
<option value="http://www.webdeveloper.com/forum/forumdisplay.php?f=3">JavaScript Forums</option>
<option value="http://www.scriptsearch.com/">Script Search</option>
<option value="http://www.webreference.com/programming/javascript/diaries/">The JavaScript Diaries</option>
</select> 

Just type in any URL you like, or a relative URL (to the pages location on server), it will always work.

You can do it with built-in RegExp(pattern[, flags]) Factory Notation in js like this:

RegExp(/-(.*)/).exec("sometext-20202")[1]

in above code exec function will return an array with two elements (["-20202", "20202"]) one with hyphen(-20202) and one without hyphen(20202) , you should pick second element (index 1)

for (id subview in webView.subviews)
  if ([[subview class] isSubclassOfClass: [UIScrollView class]])
    ((UIScrollView *)subview).bounces = NO;

...seems to work fine.

It'll be accepted to App Store as well.

Update: in iOS 5.x+ there's an easier way - UIWebView has scrollView property, so your code can look like this:

webView.scrollView.bounces = NO;

Same goes for WKWebView.

Based on the best answers of this question I have made a prototype for String called padLeft (exactly like we have in C#):

String.prototype.padLeft = function (paddingChar, totalWidth) {
    if (this.toString().length >= totalWidth)
        return this.toString();

    var array = new Array(totalWidth); 

    for (i = 0; i < array.length; i++)
        array[i] = paddingChar;

    return (array.join("") + this.toString()).slice(-array.length);
}

Usage:

var str = "12345";
console.log(str.padLeft("0", 10)); //Result is: "0000012345"

JsFiddle

Another approach that no one has mentioned is to add case insensitive finders into ActiveRecord::Base. Details can be found here. The advantage of this approach is that you don't have to modify every model, and you don't have to add the lower() clause to all your case insensitive queries, you just use a different finder method instead.

Current date and time

$current_date_time = date('Y-m-d H:i:s');

15 min ago Date and time

$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));

You are looking for str.rsplit(), with a limit:

print x.rsplit('-', 1)[0]

.rsplit() searches for the splitting string from the end of input string, and the second argument limits how many times it'll split to just once.

Another option is to use str.rpartition(), which will only ever split just once:

print x.rpartition('-')[0]

For splitting just once, str.rpartition() is the faster method as well; if you need to split more than once you can only use str.rsplit().

Demo:

>>> x = 'http://test.com/lalala-134'
>>> print x.rsplit('-', 1)[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rsplit('-', 1)[0]
'something-with-a-lot-of'

and the same with str.rpartition()

>>> print x.rpartition('-')[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rpartition('-')[0]
'something-with-a-lot-of'

If your data is from json, you can do that

import json

json.loads('true')

True

1- Never use Response.Write.

2- I put the code below after create (not in Page_Load) a LinkButton (dynamically) and solved my problem:

ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
scriptManager.RegisterPostBackControl(lblbtndoc1);

I haven't seen any decompilers that generate C++ code. I've seen a few experimental ones that make a reasonable attempt at generating C code, but they tended to be dependent on matching the code-generation patterns of a particular compiler (that may have changed, it's been awhile since I last looked into this). Of course any symbolic information will be gone. Google for "decompiler".

Add this function at the beginning of your script :

import sys, os 
    def resource_path(relative_path):
        if hasattr(sys, '_MEIPASS'):
            return os.path.join(sys._MEIPASS, relative_path)
        return os.path.join(os.path.abspath("."), relative_path)

Refer to your data files by calling the function resource_path(), like this:

resource_path('myimage.gif')

Then use this command:

pyinstaller --onefile --windowed --add-data todo.ico;. script.py

Cygwin mount now support bind method which lets you mount a directory. Hence you can simply add the following line to /etc/fstab, then restart your shell:

c:/Users /home none bind 0 0

One liner for Swift:

NSAttributedString(string: "Red Text", attributes: [.foregroundColor: UIColor.red])

If you want to run a few scripts, you can use Set-executionpolicy -ExecutionPolicy Unrestricted and then reset with Set-executionpolicy -ExecutionPolicy Default.

Note that execution policy is only checked when you start its execution (or so it seems) and so you can run jobs in the background and reset the execution policy immediately.

# Check current setting
Get-ExecutionPolicy

# Disable policy
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
# Choose [Y]es

Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 example.com | tee ping__example.com.txt }
Start-Job { cd c:\working\directory\with\script\ ; ./ping_batch.ps1 google.com  | tee ping__google.com.txt  }

# Can be run immediately
Set-ExecutionPolicy -ExecutionPolicy Default
# [Y]es

you can use too:

val frases = arrayOf("texto01","texto02 ","anotherText","and ")

for example.

you can try just add

network_mode: "host"

example :

version: '2'
services:
  feedx:
    build: web
    ports:
    - "127.0.0.1:8000:8000"
    network_mode: "host"

list option available

network_mode: "bridge"
network_mode: "host"
network_mode: "none"
network_mode: "service:[service name]"
network_mode: "container:[container name/id]"

I'd just drop the database and then re-create it. On a UNIX or Linux system, that should do it:

$ dropdb development_db_name
$ createdb developmnent_db_name

That's how I do it, actually.
