I have faced the same issue while fetching elements using jQuery and data-* attribute.

so for your reference the shortest code is here:

This is my HTML Code:

<section data-js="carousel"></section>
<section></section>
<section></section>
<section data-js="carousel"></section>

This is my jQuery selector:

$('section[data-js="carousel"]');
// this will return array of the section elements which has data-js="carousel" attribute.

Static tStart As Single, tEnd As Single, myInterval As Integer
myInterval = 5 ' seconds
tStart = VB.Timer()
tEnd = myInterval + VB.Timer()
Do While tEnd > tStart
    Application.DoEvents()
    tStart = VB.Timer()
Loop

void    QWidget::setWindowTitle ( const QString & )

EDIT: If you are using QtDesigner, on the property tab, there is an editable property called windowTitle which can be found under the QWidget section. The property tab can usually be found on the lower right part of the designer window.

Thank you @mfitzp. In my case (CentOS) these libs are not available in the yum repo, but actually the solution was even easier. What I did:

sudo yum install python-devel
sudo yum install zlib-devel
sudo yum install libjpeg-turbo-devel

And now pillow's installation finishes successfully.

I know this question is asking about jquery, but for those people using jqueryui, there are constants for many of the keycodes:

$.ui.keyCode.ESCAPE

http://api.jqueryui.com/jQuery.ui.keyCode/

Take a look at this answer: ImportError: no module named win32api

You can use

pip install pypiwin32

In my case I got this error because of a line

<script src="#"></script> 

Chrome tried to interpret the current HTML file then as javascript.

As mentioned here (in French), this can happen when you have two versions of R installed on your computer. Uninstall the oldest one, then try your package installation again! It worked fine for me.

Check file/folder permissions

I struggled with this error today, and no amount of cache, config, autoload clears did anything to help. To add to the confusion, the error was thrown if initiated by a web request, but accessing the class in tinker worked fine.

After checking for typo's, syntax errors, and incorrect namespaces, I ended up discovering it was a file permission issue. The folder and file containing my class did not have appropriate permissions so it was throwing this error. The incorrect permission level I had was 771 (folder) and 660 (file), by changing it to 775 and 664 I was able to get it working.

My understanding of the different behaviors is that when running from the command line it was reading the file as my user (which had all the permissions it needed), but when initiated from the web it uses the "other" permission group which could do nothing.

DELETE 
FROM m_productprice B  
     USING m_product C 
WHERE B.m_product_id = C.m_product_id AND
      C.upc = '7094' AND                 
      B.m_pricelist_version_id='1000020';

or

DELETE 
FROM m_productprice
WHERE m_pricelist_version_id='1000020' AND 
      m_product_id IN (SELECT m_product_id 
                       FROM m_product 
                       WHERE upc = '7094'); 

One more option is require-dir-all combining features from most popular packages.

Most popular require-dir does not have options to filter the files/dirs and does not have map function (see below), but uses small trick to find module's current path.

Second by popularity require-all has regexp filtering and preprocessing, but lacks relative path, so you need to use __dirname (this has pros and contras) like:

var libs = require('require-all')(__dirname + '/lib');

Mentioned here require-index is quite minimalistic.

With map you may do some preprocessing, like create objects and pass config values (assuming modules below exports constructors):

// Store config for each module in config object properties 
// with property names corresponding to module names 
var config = {
  module1: { value: 'config1' },
  module2: { value: 'config2' }
};

// Require all files in modules subdirectory 
var modules = require('require-dir-all')(
  'modules', // Directory to require 
  { // Options 
    // function to be post-processed over exported object for each require'd module 
    map: function(reqModule) {
      // create new object with corresponding config passed to constructor 
      reqModule.exports = new reqModule.exports( config[reqModule.name] );
    }
  }
);

// Now `modules` object holds not exported constructors, 
// but objects constructed using values provided in `config`.

I don't like adding new package into my project just to handle this simple task.

And also, I try my best to avoid RECURSIVE algorithm.... since, for most cases it is slower compared to non Recursive one.

So I made a function to get all the folder content (and its sub folder).... NON-Recursively

var getDirectoryContent = function(dirPath) {
    /* 
        get list of files and directories from given dirPath and all it's sub directories
        NON RECURSIVE ALGORITHM
        By. Dreamsavior
    */
    var RESULT = {'files':[], 'dirs':[]};

    var fs = fs||require('fs');
    if (Boolean(dirPath) == false) {
        return RESULT;
    }
    if (fs.existsSync(dirPath) == false) {
        console.warn("Path does not exist : ", dirPath);
        return RESULT;
    }

    var directoryList = []
    var DIRECTORY_SEPARATOR = "\\";
    if (dirPath[dirPath.length -1] !== DIRECTORY_SEPARATOR) dirPath = dirPath+DIRECTORY_SEPARATOR;

    directoryList.push(dirPath); // initial

    while (directoryList.length > 0) {
        var thisDir  = directoryList.shift(); 
        if (Boolean(fs.existsSync(thisDir) && fs.lstatSync(thisDir).isDirectory()) == false) continue;

        var thisDirContent = fs.readdirSync(thisDir);
        while (thisDirContent.length > 0) { 
            var thisFile  = thisDirContent.shift(); 
            var objPath = thisDir+thisFile

            if (fs.existsSync(objPath) == false) continue;
            if (fs.lstatSync(objPath).isDirectory()) { // is a directory
                let thisDirPath = objPath+DIRECTORY_SEPARATOR; 
                directoryList.push(thisDirPath);
                RESULT['dirs'].push(thisDirPath);

            } else  { // is a file
                RESULT['files'].push(objPath); 

            } 
        } 

    }
    return RESULT;
}

the only drawback of this function is that this is Synchronous function... You have been warned ;)

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

You can use SELECT as lambacck said or add parentheses:

SET @times = (SELECT COUNT(DidWin)as "I Win"
FROM thetable
WHERE DidWin = 1 AND Playername='Me');

Assuming a windows OS as you mention i p config

If you're willing to install some Unixy utilities like a windows-port of grep and cut you can do that. However, in cases like your example with ipconfig it will be a mess in machines with multiple NICs or e.g VMWare.

Powershell might be the tool you want, look here for a example.

You can also use:

button.setStyleSheet("qproperty-icon: url(:/path/to/images.png);");

Note: This is a little hacky. You should use this only as last resort. Icons should be set from C++ code or Qt Designer.

I have faced a similar problem when there were millions of useless log files created by an application which filled up all inodes. I resorted to "locate", got all the files "located"d into a text file and then removed them one by one. Took a while but did the job!

Here's the exact definition of UsedRange (MSDN reference) :

Every Worksheet object has a UsedRange property that returns a Range object representing the area of a worksheet that is being used. The UsedRange property represents the area described by the farthest upper-left and farthest lower-right nonempty cells in a worksheet and includes all cells in between.

So basically, what that line does is :

1. .UsedRange -> "Draws" a box around the outer-most cells with content inside.
2. .Columns -> Selects the entire columns of those cells
3. .Count -> Returns an integer corresponding to how many columns there are (in this selection)
4. - 8 -> Subtracts 8 from the previous integer.

I assume VBA calculates the UsedRange by finding the non-empty cells with lowest and highest index values.

Most likely, you're getting an error because the number of lines in your range is smaller than 3, and therefore the number returned is negative.

If you keep in mind that Docker is still running in a VM, the system paths are relative to the VM and not from the Mac Osx system. As it says all is contained in a VM file :

/Users/MyUserName/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2

Try to run Alpine image with this volume option and the ls command you are able to list the VM host:

docker run --rm -it -v /:/vm-root alpine:edge ls -l /vm-root

After this just try :

docker run --rm -it -v /:/vm-root alpine:edge ls -l /vm-root/var/lib/docker

Now, you are able to list the docker folder from the VM host

Note that Git 2.5 (Q2 2015) a future Git might try to make that scenario impossible.

Note: This has been reverted. See below.

stash: require a clean index to apply/pop

Problem

If you have staged contents in your index and run "stash apply/pop", we may hit a conflict and put new entries into the index.
Recovering to your original state is difficult at that point, because tools like "git reset --keep" will blow away anything staged.

In other words:

"git stash pop/apply" forgot to make sure that not just the working tree is clean but also the index is clean.
The latter is important as a stash application can conflict and the index will be used for conflict resolution.

Solution

We can make this safer by refusing to apply when there are staged changes.

That means if there were merges before because of applying a stash on modified files (added but not committed), now they would not be any merges because the stash apply/pop would stop immediately with:

Cannot apply stash: Your index contains uncommitted changes.

Forcing you to commit the changes means that, in case of merges, you can easily restore the initial state( before git stash apply/pop) with a git reset --hard.

See commit 1937610 (15 Jun 2015), and commit ed178ef (22 Apr 2015) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit bfb539b, 24 Jun 2015)}

That commit was an attempt to improve the safety of applying a stash, because the application process may create conflicted index entries, after which it is hard to restore the original index state.

Unfortunately, this hurts some common workflows around "git stash -k", like:

git add -p       ;# (1) stage set of proposed changes
git stash -k     ;# (2) get rid of everything else
make test        ;# (3) make sure proposal is reasonable
git stash apply  ;# (4) restore original working tree

If you "git commit" between steps (3) and (4), then this just works. However, if these steps are part of a pre-commit hook, you don't have that opportunity (you have to restore the original state regardless of whether the tests passed or failed).

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.

I think the question is not 100% answered. I was searching for issue with missing typeof(), which is compile time directive.

Following links will shine light on the situation:

https://gcc.gnu.org/onlinedocs/gcc-5.3.0/gcc/Typeof.html

https://gcc.gnu.org/onlinedocs/gcc-5.3.0/gcc/Alternate-Keywords.html#Alternate-Keywords

as of conculsion try to use __typeof__() instead. Also gcc ... -Dtypeof=__typeof__ ... can help.

The Default Expiration Period for Session is 20 Minutes.

You can update sessionstate and configure the minutes under timeout

<sessionState 
timeout="30">
</sessionState>

Don't know exactly what kind of dataset you have, so I provide general answer.

A very elegant way is to use ng-controller to run a single controller outside of the ng-view:

<div class="collapse navbar-collapse" ng-controller="HeaderController">
    <ul class="nav navbar-nav">
        <li ng-class="{ active: isActive('/')}"><a href="/">Home</a></li>
        <li ng-class="{ active: isActive('/dogs')}"><a href="/dogs">Dogs</a></li>
        <li ng-class="{ active: isActive('/cats')}"><a href="/cats">Cats</a></li>
    </ul>
</div>
<div ng-view></div>

and include in controllers.js:

function HeaderController($scope, $location) 
{ 
    $scope.isActive = function (viewLocation) { 
        return viewLocation === $location.path();
    };
}

Objective-c:

NSString *day = [@"10/04/2011" componentsSeparatedByString:@"/"][0];

Swift:

var day: String = "10/04/2011".componentsSeparatedByString("/")[0]

Any color parse into int simplest two way here:

1) Get System Color

int redColorValue = Color.RED;

2) Any Color Hex Code as a String Argument

int greenColorValue = Color.parseColor("#00ff00")

MUST REMEMBER in above code Color class must be android.graphics...!

If you use Unicode Character Set, but the entry wasn't set, you can specify /ENTRY:"wWinMainCRTStartup"

I had a weird encounter with this problem. when renaming variable name to user_name, I mistakenly rename all of the name to user_name for the project. So my xml tag <color name:""> became <color user_name:""> same goes for string, style, manifest too. But when I check merged manifest, it showed nothing, because I had only one manifest, nothing to find.

So, check if you have any malformed xml file or not.

These types of arrays are known as jagged arrays in Java:

int[][] multD = new int[3][];
multD[0] = new int[3];
multD[1] = new int[2];
multD[2] = new int[5];

In this scenario each row of the array holds the different number of columns. In the above example, the first row will hold three columns, the second row will hold two columns, and the third row holds five columns. You can initialize this array at compile time like below:

 int[][] multD = {{2, 4, 1}, {6, 8}, {7, 3, 6, 5, 1}};

You can easily iterate all elements in your array:

for (int i = 0; i<multD.length; i++) {
    for (int j = 0; j<multD[i].length; j++) {
        System.out.print(multD[i][j] + "\t");
    }
    System.out.println();
}

var last = objList.LastOrDefault();
foreach (var item in objList)
{
  if (item.Equals(last))
  {
  
  }
}

For using dictionary object in typescript you can use interface as below:

interface Dictionary<T> {
    [Key: string]: T;
}

and, use this for your class property type.

export class SearchParameters {
    SearchFor: Dictionary<string> = {};
}

to use and initialize this class,

getUsers(): Observable<any> {
        var searchParams = new SearchParameters();
        searchParams.SearchFor['userId'] = '1';
        searchParams.SearchFor['userName'] = 'xyz';

        return this.http.post(searchParams, 'users/search')
            .map(res => {
                return res;
            })
            .catch(this.handleError.bind(this));
    }

You can use a constant (i.e. a static, final variable) as the parameter for an annotation. As a quick example, I use something like this fairly often:

import org.junit.Test;
import static org.junit.Assert.*;

public class MyTestClass
{
    private static final int TEST_TIMEOUT = 60000; // one minute per test

    @Test(timeout=TEST_TIMEOUT)
    public void testJDK()
    {
        assertTrue("Something is very wrong", Boolean.TRUE);
    }
}

Note that it's possible to pass the TEST_TIMEOUT constant straight into the annotation.

Offhand, I don't recall ever having tried this with an array, so you may be running into some issues with slight differences in how arrays are represented as annotation parameters compared to Java variables? But as for the other part of your question, you could definitely use a constant String without any problems.

EDIT: I've just tried this with a String array, and didn't run into the problem you mentioned - however the compiler did tell me that the "attribute value must be constant" despite the array being defined as public static final String[]. Perhaps it doesn't like the fact that arrays are mutable? Hmm...

I left something like this as a comment, but I feel it probably needs more visibility as none of the answers mention this method:

The method I now prefer for initializing a std::string with non-printing characters in general (and embedded null characters in particular) is to use the C++11 feature of initializer lists.

std::string const str({'\0', '6', '\a', 'H', '\t'});

I am not required to perform error-prone manual counting of the number of characters that I am using, so that if later on I want to insert a '\013' in the middle somewhere, I can and all of my code will still work. It also completely sidesteps any issues of using the wrong escape sequence by accident.

The only downside is all of those extra ' and , characters.

I had the same problem , and i found the solution , and it works like a charm

just set the flag multi to true like this :

 db.Collection.update(
                {_id_receiver: id_receiver},
               {$set: {is_showed: true}},
                {multi: true}   /* --> multiple update */
            , function (err, updated) {...});

i hope that helps :)

Use (on Linux): cd android ./gradlew assemblyRelease|assemblyDebug

An unsigned APK is generated for each case (for debug or testing)

NOTE: On Windows, replace gradle executable for gradlew.bat

In Tomcat 8 you can also use the rewrite-valve

RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^/(.*)$         /somethingelse/index.jsp

To setup the rewrite-valve look here:

http://tonyjunkes.com/blog/a-brief-look-at-the-rewrite-valve-in-tomcat-8/

You can also use STDIN.each_line, and STDIN.each_line.to_a to get it as an array.

e.g.

STDIN.each_line do |line|
  puts line
end

simply use:

PorterDuff.Mode mode = PorterDuff.Mode.SRC_IN;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
    mode = PorterDuff.Mode.MULTIPLY;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
    progressBar.setProgressBackgroundTintList(ColorStateList.valueOf(Color.RED));
} else {
    Drawable progressDrawable;
    progressDrawable = (progressBar.isIndeterminate() ? progressBar.getIndeterminateDrawable() : progressBar.getProgressDrawable()).mutate();
    progressDrawable.setColorFilter(context.getResources().getColor(Color.RED), mode);
    progressBar.setProgressDrawable(progressDrawable);
}

You need ImageMagick and GhostScript

<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

The [0] means page 1.

fastest one:

$("div#selected ul li").length

This is fastest way I know of, even though you said you didn't want to use regular expressions:

Regex.Replace(XML, @"\s+", "")

System.Convert.IsDbNull][1](table.rows[0][0]);

IIRC, the (table.rows[0][0] == null) won't work, as DbNull.Value != null;

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

import java.util.*:
public class Logic {
  List<String> list = new ArrayList<String>();
  public static void main(String...args) {
  Scanner input = new Scanner(System.in);
    Logic obj = new Logic();
      for (int i=0;i<=20;i++) {
        String string = input.nextLine();
        obj.myLogic(string);
        obj.printList();
      }
 }
 public void myLogic(String strObj) {
   if (this.list.size()>=10) {
      this.list.remove(this.list.size()-1);
   } else {
     list.add(strObj); 
   }
 }
 public void printList() {
 System.out.print(this.list);
 }
}

This is how you can do that with ES6:

className = {`
      text-right
      ${itemId === activeItemId ? 'active' : ''}
      ${anotherProperty === true ? 'class1' : 'class2'}
`}

You can list multiple classes and conditions and also you can include static classes. It is not necessary to add an additional library.

Good luck ;)

Can't you just change working directory within the python script using os.chdir(target)? I agree, I can't see any way of doing it from the jar command itself.

If you don't want to permanently change directory, then store the current directory (using os.getcwd())in a variable and change back afterwards.

Just set the property directly: .

eleman.disabled = false;

Essentially console.log() allows you to output variables in your javascript debugger of choice instead of flashing an alert() every time you want to inspect something... additionally, for more complex objects it will give you a tree view to inspect the object further instead of having to convert elements to strings like an alert().

What does your text file look like?? Each line a record?

You'll have to check out the BULK INSERT statement - that should look something like:

BULK INSERT dbo.YourTableName
FROM 'D:\directory\YourFileName.csv'
WITH
(
  CODEPAGE = '1252',
  FIELDTERMINATOR = ';',
  CHECK_CONSTRAINTS
) 

Here, in my case, I'm importing a CSV file - but you should be able to import a text file just as well.

From the MSDN docs - here's a sample that hopefully works for a text file with one field per row:

BULK INSERT dbo.temp 
   FROM 'c:\temp\file.txt'
   WITH 
      (
         ROWTERMINATOR ='\n'
      )

Seems to work just fine in my test environment :-)

I tried some of your solutions. This one :

margin: 0px -100%;
padding: 0 100%;

is by far the best, since we don't need extra css for smaller screen. I made a codePen to show the results : I used a parent div with a background image, and a child divon div with inner content.

You can use the built-in Dir function or the FileSystemObject.

• Dir Function: VBA: Dir Function

• FileSystemObject: VBA: FileSystemObject - Files Collection

They each have their own strengths and weaknesses.

Dir Function

The Dir Function is a built-in, lightweight method to get a list of files. The benefits for using it are:

• Easy to Use
• Good performance (it's fast)
• Wildcard support

The trick is to understand the difference between calling it with or without a parameter. Here is a very simple example to demonstrate:

Public Sub ListFilesDir(ByVal sPath As String, Optional ByVal sFilter As String)

    Dim sFile As String

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file name
    sFile = Dir(sPath & sFilter)

   'call it again until there are no more files
    Do Until sFile = ""

        Debug.Print sFile

        'subsequent calls without param return next file name
        sFile = Dir

    Loop

End Sub

If you alter any of the files inside the loop, you will get unpredictable results. It is better to read all the names into an array of strings before doing any operations on the files. Here is an example which builds on the previous one. This is a Function that returns a String Array:

Public Function GetFilesDir(ByVal sPath As String, _
    Optional ByVal sFilter As String) As String()

    'dynamic array for names
    Dim aFileNames() As String
    ReDim aFileNames(0)

    Dim sFile As String
    Dim nCounter As Long

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file
    sFile = Dir(sPath & sFilter)

    'call it until there is no filename returned
    Do While sFile <> ""

        'store the file name in the array
        aFileNames(nCounter) = sFile

        'subsequent calls without param return next file
        sFile = Dir

        'make sure your array is large enough for another
        nCounter = nCounter + 1
        If nCounter > UBound(aFileNames) Then
            'preserve the values and grow by reasonable amount for performance
            ReDim Preserve aFileNames(UBound(aFileNames) + 255)
        End If

    Loop

    'truncate the array to correct size
    If nCounter < UBound(aFileNames) Then
        ReDim Preserve aFileNames(0 To nCounter - 1)
    End If

    'return the array of file names
    GetFilesDir = aFileNames()

End Function

File System Object

The File System Object is a library for IO operations which supports an object-model for manipulating files. Pros for this approach:

• Intellisense
• Robust object-model

You can add a reference to to "Windows Script Host Object Model" (or "Windows Scripting Runtime") and declare your objects like so:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As FileSystemObject
    Dim oFolder As Folder
    Dim oFile As File

    Set oFSO = New FileSystemObject
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you don't want intellisense you can do like so without setting a reference:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you have a database(working in visual studio), make sure there are no foreign keys in the tables, I had foreign keys and it gave me this error and when I removed them it ran smoothly

To work around the Mac incompatibility, I came up with

echo `php -r "echo realpath('foo');"`

Not great but cross OS

The only one that works across IE, Firefox, chrome, safari and opera if there are no spaces in the word (such as a long URL) is:

div{
    width: 200px;  
    word-break: break-all;
}

I found this to be bullet-proof.

just add:

width: 100% !important;

isset() is used to check if the variable is set with the value or not and Empty() is used to check if a given variable is empty or not.

isset() returns true when the variable is not null whereas Empty() returns true if the variable is an empty string.

I found this in the PHP manual comments:

function xml2array ( $xmlObject, $out = array () )
{
    foreach ( (array) $xmlObject as $index => $node )
        $out[$index] = ( is_object ( $node ) ) ? xml2array ( $node ) : $node;

    return $out;
}

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

FAST "FROM" AND "TO" METHODS

I am late to the party, but I compounded previous answers and improved over them. I think these two methods are faster than any others posted so far. I was able to convert 1,000,000 numbers from and to base 36 in under 400ms in a single core machine.

Example below is for base 62. Change the BaseChars array to convert from and to any other base.

private static readonly char[] BaseChars = 
         "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".ToCharArray();
private static readonly Dictionary<char, int> CharValues = BaseChars
           .Select((c,i)=>new {Char=c, Index=i})
           .ToDictionary(c=>c.Char,c=>c.Index);

public static string LongToBase(long value)
{
   long targetBase = BaseChars.Length;
   // Determine exact number of characters to use.
   char[] buffer = new char[Math.Max( 
              (int) Math.Ceiling(Math.Log(value + 1, targetBase)), 1)];

   var i = buffer.Length;
   do
   {
       buffer[--i] = BaseChars[value % targetBase];
       value = value / targetBase;
   }
   while (value > 0);

   return new string(buffer, i, buffer.Length - i);
}

public static long BaseToLong(string number) 
{ 
    char[] chrs = number.ToCharArray(); 
    int m = chrs.Length - 1; 
    int n = BaseChars.Length, x;
    long result = 0; 
    for (int i = 0; i < chrs.Length; i++)
    {
        x = CharValues[ chrs[i] ];
        result += x * (long)Math.Pow(n, m--);
    }
    return result;  
} 

EDIT (2018-07-12)

Fixed to address the corner case found by @AdrianBotor (see comments) converting 46655 to base 36. This is caused by a small floating-point error calculating Math.Log(46656, 36) which is exactly 3, but .NET returns 3 + 4.44e-16, which causes an extra character in the output buffer.

You can tab between div tags. Just add a tab index to the div. It's best to use jQuery and CSS classes to solve this problem. Here's a working sample tested in IE, Firefox, and Chrome (Latest versions... didn't test older).

The best solution would be to do these steps :

1. Delete the file called - V2__create_shipwreck.sql, clean and build the project again.

2. Run the project again, login into h2 and delete the table called "schema_version".

   drop table schema_version;

3. Now make V2__create_shipwreck.sql file with ddl and rerun the project again.

4. Do remember this, add version 4.1.2 for flyway-core in pom.xml like

   <dependency>
       <groupId>org.flywaydb</groupId>
       <artifactId>flyway-core</artifactId>
       <version>4.1.2</version>
   </dependency>
   

It should work now. Hope this will help.

Python is strongly typed because every object has a type, every object knows its type, it's impossible to accidentally or deliberately use an object of a type "as if" it was an object of a different type, and all elementary operations on the object are delegated to its type.

This has nothing to do with names. A name in Python doesn't "have a type": if and when a name's defined, the name refers to an object, and the object does have a type (but that doesn't in fact force a type on the name: a name is a name).

A name in Python can perfectly well refer to different objects at different times (as in most programming languages, though not all) -- and there is no constraint on the name such that, if it has once referred to an object of type X, it's then forevermore constrained to refer only to other objects of type X. Constraints on names are not part of the concept of "strong typing", though some enthusiasts of static typing (where names do get constrained, and in a static, AKA compile-time, fashion, too) do misuse the term this way.

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

As mentioned above, you can change the property of the textbox "Read Only" to "True" from the properties window.

itertools.combinations is your friend if you have Python 2.6 or greater. Otherwise, check the link for an implementation of an equivalent function.

import itertools
def findsubsets(S,m):
    return set(itertools.combinations(S, m))

S: The set for which you want to find subsets
m: The number of elements in the subset

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

pandas based solution with creating dataframe:

import pandas as pd
l = [['a', 'b', 'c'], ['aaaaaaaaaa', 'b', 'c'], ['a', 'bbbbbbbbbb', 'c']]
df = pd.DataFrame(l)

print(df)
            0           1  2
0           a           b  c
1  aaaaaaaaaa           b  c
2           a  bbbbbbbbbb  c

To remove index and header values to create output what you want you could use to_string method:

result = df.to_string(index=False, header=False)

print(result)
          a           b  c
 aaaaaaaaaa           b  c
          a  bbbbbbbbbb  c

I had the same problem:

I resolved it by adding the dependency to pom.xml as follows. Please try it.

    <dependency>

        <artifactId>genson</artifactId>
        <version>0.98</version>

Reason is , {} is the syntax of .format() so in your case .format() doesn't recognize {Hello} so it threw an error.

you can override it by using double curly braces {{}},

x = " {{ Hello }} {0} "

or

try %s for text formatting,

x = " { Hello } %s"
print x%(42)  

any():

if any(t < 0 for t in x):
    # do something

Also, if you're going to use "True in ...", make it a generator expression so it doesn't take O(n) memory:

if True in (t < 0 for t in x):

This may be a really late response but here is a solution that works. This line only recognizes th existance of files! It will not give you a false positive if directories exist.

if find /path/to/check/* -maxdepth 0 -type f | read
  then echo "Files Exist"
fi

I call it my billion-dollar mistake…At that time, I was designing the first comprehensive type system for references in an object-oriented language. My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn’t resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years. – Tony Hoare, inventor of ALGOL W.

See here for an elaborate shit storm about null in general. I do not agree with the statement that undefined is another null, but it is still worth reading. And it explains, why you should avoid null at all and not just in the case you have asked. The essence is, that null is in any language a special case. You have to think about null as an exception. undefined is different in that way, that code dealing with undefined behavior is in most cases just a bug. C and most other languages have also undefined behavior but most of them have no identifier for that in the language.

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

Edit - This answer is a solution, but a much simpler and proper approach would be setting the tabindex attribute on the canvas element (as suggested by hobberwickey).

You can't focus a canvas element. A simple work around this, would be to make your "own" focus.

var lastDownTarget, canvas;
window.onload = function() {
    canvas = document.getElementById('canvas');

    document.addEventListener('mousedown', function(event) {
        lastDownTarget = event.target;
        alert('mousedown');
    }, false);

    document.addEventListener('keydown', function(event) {
        if(lastDownTarget == canvas) {
            alert('keydown');
        }
    }, false);
}

JSFIDDLE

tooltips: {
    callbacks: {
        label: function (tooltipItem) {
            return (new Intl.NumberFormat('en-US', {
                style: 'currency',
                currency: 'USD',
            })).format(tooltipItem.value);
        }
    }
}

Here is what you are looking for. But this also changes the color of radioButton etc. So you might want to use a theme for it.

<item name="colorControlNormal">@color/colorControlNormal</item>

Date input = new Date();
LocalDateTime  conv=LocalDateTime.ofInstant(input.toInstant(), ZoneId.systemDefault());
LocalDate convDate=conv.toLocalDate();

The Date instance does contain time too along with the date while LocalDate doesn't. So you can firstly convert it into LocalDateTime using its method ofInstant() then if you want it without time then convert the instance into LocalDate.

In case people are still having trouble with this. I wrote a quick blog post about using Autolayout with UITableViews Leveraging Autolayout For Dynamic Cell Heights as well as an open source component to help make this more abstract and easier to implement. https://github.com/Raizlabs/RZCellSizeManager

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

If you use CRA(create-react-app) in your project, you can add this:

npm install react-bootstrap bootstrap

If you use bootstrap in your app and if it's not working, then use this in index.html :

<link
  rel="stylesheet"
  href="https://maxcdn.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css"

  crossorigin="anonymous"
/>

I did the above to solve similar problem. Hopefully this is useful to you :-)

Note added August 2013, updated February 2015: The answer below from 2009 relates to JavaScript's generic Array type. It doesn't relate to the newer typed arrays defined in ES2015 [and available now in many browsers], like Int32Array and such. Also note that ES2015 adds a fill method to both Arrays and typed arrays, which is likely to be the most efficient way to fill them...

Also, it can make a big difference to some implementations how you create the array. Chrome's V8 engine, in particular, tries to use a highly-efficient, contiguous-memory array if it thinks it can, shifting to the object-based array only when necessary.

With most languages, it would be pre-allocate, then zero-fill, like this:

function newFilledArray(len, val) {
    var rv = new Array(len);
    while (--len >= 0) {
        rv[len] = val;
    }
    return rv;
}

But, JavaScript arrays aren't really arrays, they're key/value maps just like all other JavaScript objects, so there's no "pre-allocate" to do (setting the length doesn't allocate that many slots to fill), nor is there any reason to believe that the benefit of counting down to zero (which is just to make the comparison in the loop fast) isn't outweighed by adding the keys in reverse order when the implementation may well have optimized their handling of the keys related to arrays on the theory you'll generally do them in order.

In fact, Matthew Crumley pointed out that counting down is markedly slower on Firefox than counting up, a result I can confirm — it's the array part of it (looping down to zero is still faster than looping up to a limit in a var). Apparently adding the elements to the array in reverse order is a slow op on Firefox. In fact, the results vary quite a bit by JavaScript implementation (which isn't all that surprising). Here's a quick and dirty test page (below) for browser implementations (very dirty, doesn't yield during tests, so provides minimal feedback and will run afoul of script time limits). I recommend refreshing between tests; FF (at least) slows down on repeated tests if you don't.

The fairly complicated version that uses Array#concat is faster than a straight init on FF as of somewhere between 1,000 and 2,000 element arrays. On Chrome's V8 engine, though, straight init wins out every time...

Sqlite helper class helps us to manage database creation and version management. SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.

Example to create a MyEmployees table and to select and insert records:

public class MyDatabaseHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "DBName";

    private static final int DATABASE_VERSION = 2;

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table MyEmployees
                                 ( _id integer primary key,name text not null);";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database,
    @Override
    public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
        Log.w(MyDatabaseHelper.class.getName(),
                         "Upgrading database from version " + oldVersion + " to "
                         + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS MyEmployees");
        onCreate(database);
    }
}

Now you can use this class as below,

public class MyDB{  

    private MyDatabaseHelper dbHelper;  

    private SQLiteDatabase database;  

    public final static String EMP_TABLE="MyEmployees"; // name of table 

    public final static String EMP_ID="_id"; // id value for employee
    public final static String EMP_NAME="name";  // name of employee

    /** 
     * 
     * @param context 
     */  
    public MyDB(Context context){  
        dbHelper = new MyDatabaseHelper(context);  
        database = dbHelper.getWritableDatabase();  
    }


    public long createRecords(String id, String name){  
        ContentValues values = new ContentValues();  
        values.put(EMP_ID, id);  
        values.put(EMP_NAME, name);  
        return database.insert(EMP_TABLE, null, values);  
    }    

    public Cursor selectRecords() {
        String[] cols = new String[] {EMP_ID, EMP_NAME};  
        Cursor mCursor = database.query(true, EMP_TABLE,cols,null  
            , null, null, null, null, null);  
        if (mCursor != null) {  
            mCursor.moveToFirst();  
        }  
        return mCursor; // iterate to get each value.
    }
}

Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.

• but i already assigned values such that irp.WrmVersion = "10.4";

J.Random Coder's answer and initialize version field.

private string version = "10.4';

Because you didn't specify the Header.

I've added an extended example:

var request = (HttpWebRequest)WebRequest.Create(strServer + strURL.Split('&')[1].ToString());

Header(ref request, p_Method);

And the method Header:

private void Header(ref HttpWebRequest p_request, string p_Method)
{
    p_request.ContentType = "application/x-www-form-urlencoded";
    p_request.Method = p_Method;
    p_request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)";
    p_request.Host = strServer.Split('/')[2].ToString();
    p_request.Accept = "*/*";
    if (String.IsNullOrEmpty(strURLReferer))
    {
        p_request.Referer = strServer;
    }
    else
    {
        p_request.Referer = strURLReferer;
    }
    p_request.Headers.Add("Accept-Language", "en-us\r\n");
    p_request.Headers.Add("UA-CPU", "x86 \r\n");
    p_request.Headers.Add("Cache-Control", "no-cache\r\n");
    p_request.KeepAlive = true;
}

NSString *str1 = @"Share Role Play Photo via Facebook, or Twitter for free coins per photo.";
NSString *str2 = @"Like Role Play on facebook for 50 free coins.";
NSString *str3 = @"Check out 'What's Hot' on other ways to receive free coins";


NSString *msg = [NSString stringWithFormat:@"%@\n%@\n%@", str1, str2, str3];

You could try:

alist[:] = []

Which means: Splice in the list [] (0 elements) at the location [:] (all indexes from start to finish)

The [:] is the slice operator. See this question for more information.

For example,

package main

import "fmt"

func main() {
    s := "abc"
    var a [20]byte
    copy(a[:], s)
    fmt.Println("s:", []byte(s), "a:", a)
}

Output:

s: [97 98 99] a: [97 98 99 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]

It's better to use lambda functions using df.apply() -

df["ifor"] = df.apply(lambda x: {value} if {condition} else x["ifor"], axis=1)

    d['ModDate'] = datetime.datetime.today()

If you have a Unicode string, and you want to write this to a file, or other serialised form, you must first encode it into a particular representation that can be stored. There are several common Unicode encodings, such as UTF-16 (uses two bytes for most Unicode characters) or UTF-8 (1-4 bytes / codepoint depending on the character), etc. To convert that string into a particular encoding, you can use:

>>> s= u'£10'
>>> s.encode('utf8')
'\xc2\x9c10'
>>> s.encode('utf16')
'\xff\xfe\x9c\x001\x000\x00'

This raw string of bytes can be written to a file. However, note that when reading it back, you must know what encoding it is in and decode it using that same encoding.

When writing to files, you can get rid of this manual encode/decode process by using the codecs module. So, to open a file that encodes all Unicode strings into UTF-8, use:

import codecs
f = codecs.open('path/to/file.txt','w','utf8')
f.write(my_unicode_string)  # Stored on disk as UTF-8

Do note that anything else that is using these files must understand what encoding the file is in if they want to read them. If you are the only one doing the reading/writing this isn't a problem, otherwise make sure that you write in a form understandable by whatever else uses the files.

In Python 3, this form of file access is the default, and the built-in open function will take an encoding parameter and always translate to/from Unicode strings (the default string object in Python 3) for files opened in text mode.

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

This is with jQuery.

$('#selectFormElement').change( function() {
    $('#hiddenFormElement').val('newValue');
} );

In the html

<select id="selectFormElement" name="..."> ... </select>
<input type="hidden" name="..." id="hiddenFormElement" />

toString is a function, not a property. You'll want this:

console.log(aa.toString());

Alternatively, use join to specify the separator (toString() === join(','))

console.log(aa.join(' and '));

It should also be possible to create a controller that returns the ico file and register the route /favicon.ico to point to that controller.

Set the href attribute as href="javascript:;"

<ul class="product-info">
  <li>
   <a href="javascript:;">YOU CLICK THIS TO SHOW/HIDE</a>
  <div class="toggle">
    <p>CONTENT TO SHOW/HIDE</p>
  </div>
 </li>
</ul>

Minimal example

And just to make what Mizux said as a minimal example:

main_c.c

#include <stdio.h>

int main(void) {
    puts("hello");
}

main_cpp.cpp

#include <iostream>

int main(void) {
    std::cout << "hello" << std::endl;
}

Then, without any Makefile:

make CFLAGS='-g -O3' \
     CXXFLAGS='-ggdb3 -O0' \
     CPPFLAGS='-DX=1 -DY=2' \
     CCFLAGS='--asdf' \
     main_c \
     main_cpp

runs:

cc -g -O3 -DX=1 -DY=2   main_c.c   -o main_c
g++ -ggdb3 -O0 -DX=1 -DY=2   main_cpp.cpp   -o main_cpp

So we understand that:

• make had implicit rules to make main_c and main_cpp from main_c.c and main_cpp.cpp
• CFLAGS and CPPFLAGS were used as part of the implicit rule for .c compilation
• CXXFLAGS and CPPFLAGS were used as part of the implicit rule for .cpp compilation
• CCFLAGS is not used

Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:

main_c: main_c.c
    $(CC) $(CFLAGS) $(CPPFLAGS) -o $@ $<

main_cpp: main_c.c
    $(CXX) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

to achieve a similar affect to the implicit rules.

We could also name those variables however we want: but since Make already treats them magically in the implicit rules, those make good name choices.

Tested in Ubuntu 16.04, GNU Make 4.1.

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)

Here is the FIX for 2.3 and below when using colours:

• Android: Entire ListView changes color on focus, not just ListView child item

As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape drawable containing the colour you want, and to use that instead of the colour.

I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

I am working on a program that saves its data properly to %APPDATA%, but sometimes, there are system-wide settings that affect all users. So in these situations, it HAS to write to the programs installation directory.

And as far as I have read now, it's impossible to temporarily get write access to one directory. You can only run the whole application as administrator (which should be out of the question) or not be able to save that file. (all or nothing)

I guess, I will just write the file to %APPDATA% and launch an external program that copies the file into the installation folder and have THAT program demand admin privileges... dumb idea, but seems to be the only practical solution...

You can set values from html like this. I don't think there is a direct solution from angular yet.

 <div style="visibility: hidden;">{{activeTitle='home'}}</div>

In Robins's answer ends-with is not supported in xpath 1.0 too.. Only starts-with is supported... So if your condition is not very specific..You can Use like this which worked for me

//*[starts-with(@id,'sometext') and contains(@name,'_text')]`\

My project was using pipenv. The following command worked for me:

pipenv install mysql-connector-python

Setting the index name can also be accomplished at creation:

pd.DataFrame(data={'age': [10,20,30], 'height': [100, 170, 175]}, index=pd.Series(['a', 'b', 'c'], name='Tag'))

Just do select date(timestamp_column) and you would get the only the date part. Sometimes doing select timestamp_column::date may return date 00:00:00 where it doesn't remove the 00:00:00 part. But I have seen date(timestamp_column) to work perfectly in all the cases. Hope this helps.

this post was made a while ago, but it provides an answer that did not solve the problem regarding reaching the limit of requests in an iteration for me, so I publish this, to help who else has not served.

My environment happened in Ionic 3.

Instead of making a "pause" in the iteration, I ocurred the idea of ??iterating with a timer, this timer has the particularity of executing the code that would go in the iteration, but will run every so often until it is reached the maximum count of the "Array" in which we want to iterate.

In other words, we will consult the Google API in a certain time so that it does not exceed the limit allowed in milliseconds.

// Code to start the timer
    this.count= 0;
    let loading = this.loadingCtrl.create({
      content: 'Buscando los mejores servicios...'
    });
    loading.present();
    this.interval = setInterval(() => this.getDistancias(loading), 40);

// Function that runs the timer, that is, query Google API
  getDistancias(loading){
    if(this.count>= this.datos.length){
      clearInterval(this.interval);
    } else {
      var sucursal = this.datos[this.count];
      this.calcularDistancia(this.posicion, new LatLng(parseFloat(sucursal.position.latitude),parseFloat(sucursal.position.longitude)),sucursal.codigo).then(distancia => {
    }).catch(error => {
      console.log('error');
      console.log(error);
    });
    }
    this.count += 1;
  }
  calcularDistancia(miPosicion, markerPosicion, codigo){
    return new Promise(async (resolve,reject) => {
      var service = new google.maps.DistanceMatrixService;
      var distance;
      var duration;
      service.getDistanceMatrix({
        origins: [miPosicion, 'salida'],
        destinations: [markerPosicion, 'llegada'],
        travelMode: 'DRIVING',
        unitSystem: google.maps.UnitSystem.METRIC,
        avoidHighways: false,
        avoidTolls: false
      }, function(response, status){
        if (status == 'OK') {
          var originList = response.originAddresses;
          var destinationList = response.destinationAddresses;
          try{
            if(response != null && response != undefined){
              distance = response.rows[0].elements[0].distance.value;
              duration = response.rows[0].elements[0].duration.text;
              resolve(distance);
            }
          }catch(error){
            console.log("ERROR GOOGLE");
            console.log(status);
          }
        }
      });
    });
  }

I hope this helps!

I'm sorry for my English, I hope it's not an inconvenience, I had to use the Google translator.

Lightweight Directory Access Protocol or LDAP, is a standards based specification for interacting with directory data. Directory Services can implement support of LDAP to provide interoperability among 3rd party applications.

Active Directory is Microsoft's implementation of a directory service that, among other protocols, supports LDAP to query it's data.

While it supports LDAP, Active Directory provides a host of extensions and conveniences, such as password expiration and account lockout.

The current best practice is to configure Jackson within the application.yml (or properties) file.

Example:

spring:
  jackson:
    property-naming-strategy: SNAKE_CASE

If you have more complex configuration requirements, you can also configure Jackson programmatically.

import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@Configuration
public class JacksonConfiguration {

    @Bean
    public Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder() {
        return new Jackson2ObjectMapperBuilder()
                .propertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
        // insert other configurations
    }

} 

First of all, if you're using method 3, you can replace those last 14 lines of code with this:

int result = myObject.calculateSomething(p1.orElse(null), p2.orElse(null));

The four variations you wrote are convenience methods. You should only use them when they're more convenient. That's also the best approach. That way, the API is very clear which members are necessary and which aren't. If you don't want to write four methods, you can clarify things by how you name your parameters:

public int calculateSomething(String p1OrNull, BigDecimal p2OrNull)

This way, it's clear that null values are allowed.

Your use of p1.orElse(null) illustrates how verbose our code gets when using Optional, which is part of why I avoid it. Optional was written for functional programming. Streams need it. Your methods should probably never return Optional unless it's necessary to use them in functional programming. There are methods, like Optional.flatMap() method, that requires a reference to a function that returns Optional. Here's its signature:

public <U> Optional<U> flatMap(Function<? super T, ? extends Optional<? extends U>> mapper)

So that's usually the only good reason for writing a method that returns Optional. But even there, it can be avoided. You can pass a getter that doesn't return Optional to a method like flatMap(), by wrapping it in a another method that converts the function to the right type. The wrapper method looks like this:

public static <T, U> Function<? super T, Optional<U>> optFun(Function<T, U> function) {
    return t -> Optional.ofNullable(function.apply(t));
}

So suppose you have a getter like this: String getName()

You can't pass it to flatMap like this:

opt.flatMap(Widget::getName) // Won't work!

But you can pass it like this:

opt.flatMap(optFun(Widget::getName)) // Works great!

Outside of functional programming, Optionals should be avoided.

Brian Goetz said it best when he said this:

The reason Optional was added to Java is because this:

return Arrays.asList(enclosingInfo.getEnclosingClass().getDeclaredMethods())
    .stream()
    .filter(m -> Objects.equals(m.getName(), enclosingInfo.getName())
    .filter(m ->  Arrays.equals(m.getParameterTypes(), parameterClasses))
    .filter(m -> Objects.equals(m.getReturnType(), returnType))
    .findFirst()
    .getOrThrow(() -> new InternalError(...));

is cleaner than this:

Method matching =
    Arrays.asList(enclosingInfo.getEnclosingClass().getDeclaredMethods())
    .stream()
    .filter(m -> Objects.equals(m.getName(), enclosingInfo.getName())
    .filter(m ->  Arrays.equals(m.getParameterTypes(), parameterClasses))
    .filter(m -> Objects.equals(m.getReturnType(), returnType))
    .getFirst();
if (matching == null)
  throw new InternalError("Enclosing method not found");
return matching;

All is explained quite nicely on gruntjs.com.

Note that installing grunt-cli does not install the grunt task runner! The job of the grunt CLI is simple: run the version of grunt which has been installed next to a Gruntfile. This allows multiple versions of grunt to be installed on the same machine simultaneously.

So in your project folder, you will need to install (preferably) the latest grunt version:

npm install grunt --save-dev

Option --save-dev will add grunt as a dev-dependency to your package.json. This makes it easy to reinstall dependencies.

I like to use this. There is nothing wrong with using the for loop, I just like using the build-in functions. You could even pass in a boolean argument for typecast or non typecast matching, which in that case you would use a for loop (the filter() method/function does typecast matching (===))

Array.prototype.unique =
function()
{
    return this.filter(
        function(val, i, arr)
        {
            return (i <= arr.indexOf(val));
        }
    );
}

Your hash is already binary and ready to be used with your database.

However you must need to convert it into a format the database column definition expects.

Any string in PHP (until 5.3) is a binary string. That means it contains only binary data.

However because of backwards compatiblity with PHP 6 you can already cast your string explicitly as binary:

 $string = 'my binary string';
 $binary = b'my binary string';

But that is merely for compatibility reasons, in your code you can just do:

  $string = $binary; // "convert" binary string into string
  $binary = $string  // "convert" string into binary string

Because it's the same. The "convert" is superfluous.

If someone is sniffing your plain-text HTTP traffic (or cache/cookies) for passwords just turning the password into a hash won't help - The hash password can be "replayed" just as well as plain-text. The client would need to hash the password with something somewhat random (like the date and time) See the section on "AUTH CRAM-MD5" here: http://www.fehcom.de/qmail/smtpauth.html

Best way to send html formatted Email

This code will be in "Customer.htm"

    <table>
    <tr>
        <td>
            Dealer's Company Name
        </td>
        <td>
            :
        </td>
        <td>
            #DealerCompanyName#
        </td>
    </tr>
</table>

Read HTML file Using System.IO.File.ReadAllText. get all HTML code in string variable.

string Body = System.IO.File.ReadAllText(HttpContext.Current.Server.MapPath("EmailTemplates/Customer.htm"));

Replace Particular string to your custom value.

Body = Body.Replace("#DealerCompanyName#", _lstGetDealerRoleAndContactInfoByCompanyIDResult[0].CompanyName);

call SendEmail(string Body) Function and do procedure to send email.

 public static void SendEmail(string Body)
        {
            MailMessage message = new MailMessage();
            message.From = new MailAddress(Session["Email"].Tostring());
            message.To.Add(ConfigurationSettings.AppSettings["RequesEmail"].ToString());
            message.Subject = "Request from " + SessionFactory.CurrentCompany.CompanyName + " to add a new supplier";
            message.IsBodyHtml = true;
            message.Body = Body;

            SmtpClient smtpClient = new SmtpClient();
            smtpClient.UseDefaultCredentials = true;

            smtpClient.Host = ConfigurationSettings.AppSettings["SMTP"].ToString();
            smtpClient.Port = Convert.ToInt32(ConfigurationSettings.AppSettings["PORT"].ToString());
            smtpClient.EnableSsl = true;
            smtpClient.Credentials = new System.Net.NetworkCredential(ConfigurationSettings.AppSettings["USERNAME"].ToString(), ConfigurationSettings.AppSettings["PASSWORD"].ToString());
            smtpClient.Send(message);
        }

Yes, first set a datetime to the start of the current month.

Second test if current date day > 25 and get a true/false on that. If True then add add one month to the start of month datetime object. If false then use the datetime object with the value set to the beginning of the month.

import datetime 
from dateutil.relativedelta import relativedelta

todayDate = datetime.date.today()
resultDate = todayDate.replace(day=1)

if ((todayDate - resultDate).days > 25):
    resultDate = resultDate + relativedelta(months=1)

print resultDate

I haven't used Angular, but reading the link above, it seems that you're trying to code for something that you don't need to handle. You make changes to state in your React component hierarchy (via this.setState()) and React will cause your component to be re-rendered (effectively 'listening' for changes). If you want to 'listen' from another component in your hierarchy then you have two options:

1. Pass handlers down (via props) from a common parent and have them update the parent's state, causing the hierarchy below the parent to be re-rendered.
2. Alternatively, to avoid an explosion of handlers cascading down the hierarchy, you should look at the flux pattern, which moves your state into data stores and allows components to watch them for changes. The Fluxxor plugin is very useful for managing this.

 public static bool AreTablesTheSame( DataTable tbl1, DataTable tbl2)
 {
    if (tbl1.Rows.Count != tbl2.Rows.Count || tbl1.Columns.Count != tbl2.Columns.Count)
                return false;


    for ( int i = 0; i < tbl1.Rows.Count; i++)
    {
        for ( int c = 0; c < tbl1.Columns.Count; c++)
        {
            if (!Equals(tbl1.Rows[i][c] ,tbl2.Rows[i][c]))
                        return false;
        }
     }
     return true;
  }

You can delete the archive files and executable binaries that go install (or go get) produces for a package with go clean -i importpath.... These normally reside under $GOPATH/pkg and $GOPATH/bin, respectively.

Be sure to include ... on the importpath, since it appears that, if a package includes an executable, go clean -i will only remove that and not archive files for subpackages, like gore/gocode in the example below.

Source code then needs to be removed manually from $GOPATH/src.

go clean has an -n flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean). It also has a tempting -r flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!

A complete example, which you could base a script on if you like:

$ go get -u github.com/motemen/gore

$ which gore
/Users/ches/src/go/bin/gore

$ go clean -i -n github.com/motemen/gore...
cd /Users/ches/src/go/src/github.com/motemen/gore
rm -f gore gore.exe gore.test gore.test.exe commands commands.exe commands_test commands_test.exe complete complete.exe complete_test complete_test.exe debug debug.exe helpers_test helpers_test.exe liner liner.exe log log.exe main main.exe node node.exe node_test node_test.exe quickfix quickfix.exe session_test session_test.exe terminal_unix terminal_unix.exe terminal_windows terminal_windows.exe utils utils.exe
rm -f /Users/ches/src/go/bin/gore
cd /Users/ches/src/go/src/github.com/motemen/gore/gocode
rm -f gocode.test gocode.test.exe
rm -f /Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore/gocode.a

$ go clean -i github.com/motemen/gore...

$ which gore

$ tree $GOPATH/pkg/darwin_amd64/github.com/motemen/gore
/Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore

0 directories, 0 files

# If that empty directory really bugs you...
$ rmdir $GOPATH/pkg/darwin_amd64/github.com/motemen/gore

$ rm -rf $GOPATH/src/github.com/motemen/gore

Note that this information is based on the go tool in Go version 1.5.1.

Instead of using -f or --force developers should use

--force-with-lease

Why? Because it checks the remote branch for changes which is absolutely a good idea. Let's imagine that James and Lisa are working on the same feature branch and Lisa has pushed a commit. James now rebases his local branch and is rejected when trying to push. Of course James thinks this is due to rebase and uses --force and would rewrite all Lisa's changes. If James had used --force-with-lease he would have received a warning that there are commits done by someone else. I don't see why anyone would use --force instead of --force-with-lease when pushing after a rebase.

Another Solution For Windows Users:

This uses Github as a bridge to get to Bitbucket, caused to the lack of publishing directly from the windows Sourcetree app.

1. Load your local repo into the Github desktop app.
2. Publish the repo as a private (for privacy - if desired) repo from the Github desktop app into your Github account.
3. Open your personal / team account in Bitbucket's website
4. Create a new Bitbucket repo by importing from Github.
5. Delete the repo in Github.

Once this is done, everything will be loaded into Bitbucket. Your local remotes will probably need to be configured to point to Bitbucket now.

the problem is in the MatInputModule:

exports: [
    MatInputModule
  ]

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

Is it very expensive to do this by json convert? But at least you have a 2 line solution and its generic. It does not matter eather if your datatable contains more or less fields than the object class:

Dim sSql = $"SELECT '{jobID}' AS ConfigNo, 'MainSettings' AS ParamName, VarNm AS ParamFieldName, 1 AS ParamSetId, Val1 AS ParamValue FROM StrSVar WHERE NmSp = '{sAppName} Params {jobID}'"
            Dim dtParameters As DataTable = DBLib.GetDatabaseData(sSql)

            Dim paramListObject As New List(Of ParameterListModel)()

            If (Not dtParameters Is Nothing And dtParameters.Rows.Count > 0) Then
                Dim json = Newtonsoft.Json.JsonConvert.SerializeObject(dtParameters).ToString()

                paramListObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of List(Of ParameterListModel))(json)
            End If

This is the answer.

<asp:TextBox id="yourtextBoxname" runat="server" AutoCompleteType="Disabled"></asp:TextBox>

AutoCompleteType="Disabled"

If you still get the pre-filled boxes for example in the Firefox browser then its the browser's fault. You have to go

'Options' --> 'Security'(tab) --> Untick

'Remember password for sites and click on Saved Passwords button to delete any details that the browser has saved.

This should solve the problem

Use this:

var table = $(selector).dataTables();
table.api().draw(false);

or

var table = $(selector).DataTables();
table.draw(false);

NPS (Node Package Scripts) solved this problem for me. It lets you put your NPM scripts into a separate JavaScript file, where you can add comments galore and any other JavaScript logic you need to. https://www.npmjs.com/package/nps

Sample of the package-scripts.js from one of my projects

module.exports = {
  scripts: {
    // makes sure e2e webdrivers are up to date
    postinstall: 'nps webdriver-update',

    // run the webpack dev server and open it in browser on port 7000
    server: 'webpack-dev-server --inline --progress --port 7000 --open',

    // start webpack dev server with full reload on each change
    default: 'nps server',

    // start webpack dev server with hot module replacement
    hmr: 'nps server -- --hot',

    // generates icon font via a gulp task
    iconFont: 'gulp default --gulpfile src/deps/build-scripts/gulp-icon-font.js',

    // No longer used
    // copyFonts: 'copyfiles -f src/app/glb/font/webfonts/**/* dist/1-0-0/font'
  }
}

I just did a local install npm install nps -save-dev and put this in my package.json scripts.

"scripts": {
    "start": "nps",
    "test": "nps test"
}

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

<?xml version="1.0" encoding="utf-8"?>
<shape 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <stroke
        android:width="10dp"
        android:color="@color/white"/>

    <gradient
        android:startColor="@color/red"
        android:centerColor="@color/red"
        android:endColor="@color/red"
        android:angle="270"/>

    <size 
        android:width="250dp" 
        android:height="250dp"/>
</shape>

select TABLE_NAME from user_tables;

Above query will give you the names of all tables present in that user;

To illustrate Nippysaurus's answer: If you are going to add the new items to the list and want to process the newly added items too during the same enumeration then you can just use for loop instead of foreach loop, problem solved :)

var list = new List<YourData>();
... populate the list ...

//foreach (var entryToProcess in list)
for (int i = 0; i < list.Count; i++)
{
    var entryToProcess = list[i];

    var resultOfProcessing = DoStuffToEntry(entryToProcess);

    if (... condition ...)
        list.Add(new YourData(...));
}

For runnable example:

void Main()
{
    var list = new List<int>();
    for (int i = 0; i < 10; i++)
        list.Add(i);

    //foreach (var entry in list)
    for (int i = 0; i < list.Count; i++)
    {
        var entry = list[i];
        if (entry % 2 == 0)
            list.Add(entry + 1);

        Console.Write(entry + ", ");
    }

    Console.Write(list);
}

Output of last example:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 3, 5, 7, 9,

How do I emulate the ISNULL() functionality ?

SELECT (Field IS NULL) FROM ...

I have reproduced the issue in my system,

postgres=# alter user my-sys with password 'pass11';
ERROR:  syntax error at or near "-"
LINE 1: alter user my-sys with password 'pass11';
                       ^

Here is the issue,

psql is asking for input and you have given again the alter query see postgres-#That's why it's giving error at alter

postgres-# alter user "my-sys" with password 'pass11';
ERROR:  syntax error at or near "alter"
LINE 2: alter user "my-sys" with password 'pass11';
        ^

Solution is as simple as the error,

postgres=# alter user "my-sys" with password 'pass11';
ALTER ROLE

I am starting a new C++ project and started looking for the latest in C++ style. I ended up here regarding file naming and I thought that I would share how I came up with my choice. Here goes:

Stroustrup sees this more as a business consideration than a technical one.

Following his advice, let's check what the toolchains expect.

For UNIX/Linux, you may interpret the following default GNU make rules as favoring the .cc filename suffix, as .cpp and .C rules are just aliases:

$ make -p | egrep COMPILE[^=]+=
COMPILE.cc = $(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c
COMPILE.cpp = $(COMPILE.cc)
COMPILE.C = $(COMPILE.cc)

(Note: there is no default COMPILE.cxx alias)

So if you are targeting UNIX/Linux, both .cc and .cpp are very good options.

When targeting Windows, you are looking for trouble with .C, as its file system is case-insensitive. And it may be important for you to note that Visual Studio favors the .cpp suffix

When targeting macOS, note that Xcode prefers .cpp/.hpp (just checked on Xcode 10.1). You can always change the header template to use .h.

For what it is worth, you can also base your decision on the code bases that you like. Google uses .cc and LLVM libc++ uses .cpp, for instance.

What about header files? They are compiled in the context of a C or C++ file, so there is no compiler or build system need to distinguish .h from .hpp. Syntax highlighting and automatic indentation by your editor/IDE can be an issue, however, but this is fixed by associating all .h files to a C++ mode. As an example, my emacs config on Linux loads all .h files in C++ mode and it edits C headers just fine. Beyond that, when mixing C and C++, you can follow this advice.

My personal conclusion: .cpp/.h is the path of least resistance.

I personally have been looking into using MinGW (what Bloodshed uses) with the Code Blocks IDE.

I am also considering using the Digital Mars C/C++ compiler.

Both seem to be well regarded.

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //if you want to interrupt going to another location.
  event.preventDefault();  });

In your app/build.gradle file, you can set the minSdkVersion inside defaultConfig.

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.name.app"
        minSdkVersion 19    // This over here
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }

Thanks for the answers guys. My problem was that I changed a x64 solution in Visual Studio to 32 bit in the Configuration Manager only. I ended up just creating a new solution as 32 bit and then copying my C++ code and this error was gone. I think l00g33k and RogerAttrill's suggestions may have been the solution, but mine worked, too.

Just wanted to provide a simple answer here. I am just messing with an old Android device for the first time doing these root and unlock procedures. I received an error like this one when an adb push "..." "/sdcard/" command failed, and the key was that my device was in the bootloader screen. Booting to recovery then allowed me copy over the file(s), and I presume the normal OS would as well.

If you have lots of commits and you only want to squash the last X commits, find the commit ID of the commit from which you want to start squashing and do

git rebase -i <that_commit_id>

Then proceed as described in leopd's answer, changing all the picks to squashes except the first one.

Example:

871adf OK, feature Z is fully implemented      --- newer commit --+
0c3317 Whoops, not yet...                                         |
87871a I'm ready!                                                 |
643d0e Code cleanup                                               |-- Join these into one
afb581 Fix this and that                                          |
4e9baa Cool implementation                                        |
d94e78 Prepare the workbench for feature Z     -------------------+
6394dc Feature Y                               --- older commit

You can either do this (write the number of commits):

git rebase --interactive HEAD~[7]

Or this (write the hash of the last commit you don't want to squash):

git rebase --interactive 6394dc

First solution: if you are using C++11

Since this was asked there were a bit of new developments: it is important to know that std::isnan() is part of C++11

Synopsis

Defined in header <cmath>

bool isnan( float arg ); (since C++11)
bool isnan( double arg ); (since C++11)
bool isnan( long double arg ); (since C++11)

Determines if the given floating point number arg is not-a-number (NaN).

Parameters

arg: floating point value

Return value

true if arg is NaN, false otherwise

Reference

http://en.cppreference.com/w/cpp/numeric/math/isnan

Please note that this is incompatible with -fast-math if you use g++, see below for other suggestions.

Other solutions: if you using non C++11 compliant tools

For C99, in C, this is implemented as a macro isnan(c)that returns an int value. The type of x shall be float, double or long double.

Various vendors may or may not include or not a function isnan().

The supposedly portable way to check for NaN is to use the IEEE 754 property that NaN is not equal to itself: i.e. x == x will be false for x being NaN.

However the last option may not work with every compiler and some settings (particularly optimisation settings), so in last resort, you can always check the bit pattern ...

I've resolved this using:

.element:before {
    font-family: "Font Awesome 5 Free" , "CircularStd";
    content: "\f017" " Date";
}

Using the font family "font awesome 5 free" for the icon, and after, We have to specify the font that we are using again because if we doesn't do this, navigator will use the default font (times new roman or something like this).

I got this error because I mistakenly mapped the ID column using Id(x => x.Id, "id").GeneratedBy.**Assigned**();

Issue resolved by using Id(x => x.Id, "id").GeneratedBy.**Identity**();

An alternative to the answer by @Marco Ponti, and avoiding the checkout:

git diff --name-only <notMainDev> $(git merge-base <notMainDev> <mainDev>)

If your particular shell doesn't understand the $() construct, use back-ticks instead.

string input;
DateTime db;
Console.WriteLine("Enter Date in this Format(YYYY-MM-DD): ");
input = Console.ReadLine();
db = Convert.ToDateTime(input);

//////// this methods convert string value to datetime
///////// in order to print date

Console.WriteLine("{0}-{1}-{2}",db.Year,db.Month,db.Day);

You can use a combination of other LINQ methods to handle not matching condition:

var res = dictionary.Where(x => x.Value.ID == someID)
                    .Select(x => x.Value.DisplayName)
                    .DefaultIfEmpty("Unknown")
                    .First();

Standard approach:

from collections import defaultdict

words = "apple banana apple strawberry banana lemon"
words = words.split()
result = defaultdict(int)
for word in words:
    result[word] += 1

print result

Groupby oneliner:

from itertools import groupby

words = "apple banana apple strawberry banana lemon"
words = words.split()

result = dict((key, len(list(group))) for key, group in groupby(sorted(words)))
print result

At its simplest:

#include <iostream>
using namespace std;

class A {
   public:
     A( int x ) : n( x ){}
     void print() { cout << n << endl; }
   private:
     int n;
};

void func( A p ) {
   p.print();
}

int main () {
   A a;
   func ( a );
}

Of course, you should probably be using references to pass the object, but I suspect you haven't got to them yet.

app.run(function ($rootScope, $location) {
    $rootScope.$on('$routeChangeSuccess', function(){
        ga('send', 'pageview', $location.path());
    });
});

Expression you are looking for may be:

...
return any( isinstance(e, list) for e in my_list )

Testing:

>>> my_list = [1,2]
>>> any( isinstance(e, list) for e in my_list )
False
>>> my_list = [1,2, [3,4,5]]
>>> any( isinstance(e, list) for e in my_list )
True
>>> 

For put method we have:

const putMethod = {
 method: 'PUT', // Method itself
 headers: {
  'Content-type': 'application/json; charset=UTF-8' // Indicates the content 
 },
 body: JSON.stringify(someData) // We send data in JSON format
}

// make the HTTP put request using fetch api
fetch(url, putMethod)
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error

Example for someData, we can have some input fields or whatever you need:

const someData = {
 title: document.querySelector(TitleInput).value,
 body: document.querySelector(BodyInput).value
}

And in our data base will have this in json format:

{
 "posts": [
   "id": 1,
   "title": "Some Title", // what we typed in the title input field
   "body": "Some Body", // what we typed in the body input field
 ]
}

For delete method we have:

const deleteMethod = {
 method: 'DELETE', // Method itself
 headers: {
  'Content-type': 'application/json; charset=UTF-8' // Indicates the content 
 },
 // No need to have body, because we don't send nothing to the server.
}
// Make the HTTP Delete call using fetch api
fetch(url, deleteMethod) 
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error

In the url we need to type the id of the of deletion: https://www.someapi/id

You can use the following regex to get integer and floating values from a string:

re.findall(r'[\d\.\d]+', 'hello -34 42 +34.478m 88 cricket -44.3')

['34', '42', '34.478', '88', '44.3']

Thanks Rex

tty: teletype. Usually refers to the serial ports of a computer, to which terminals were attached.

pty: pseudoteletype. Kernel provided pseudoserial port connected to programs emulating terminals, such as xterm, or screen.

You should find it in :

C:\Users\User Name\AppData\Local\Android\sdk\platform-tools

Add that to path, or change directory to there. The command sqlite3 is also there.

In the terminal you can type commands like

adb logcat //for logs
adb shell // for android shell

If you do not have Administrator access to the MySQL Server configuration (i.e. you are using a hosting service), then there are 2 options to get this to work:

1) Request that the old_passwords option be set to false on the MySQL server

2) Downgrade PHP to 5.2.2 until option 1 occurs.

From what I've been able to find, the issue seems to be with how the MySQL account passwords are stored and if the 'old_passwords' setting is set to true. This causes a compatibility issue between MySQL and newer versions of PHP (5.3+) where PHP attempts to connect using a 41-character hash but the MySQL server is still storing account passwords using a 16-character hash.

This incompatibility was brought about by the changing of the hashing method used in MySQL 4.1 which allows for both short and long hash lengths (Scenario 2 on this page from the MySQL site: http://dev.mysql.com/doc/refman/5.5/en/password-hashing.html) and the inclusion of the MySQL Native Driver in PHP 5.3 (backwards compatibility issue documented on bullet 7 of this page from the PHP documentation: http://www.php.net/manual/en/migration53.incompatible.php).

QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/

I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.

According to SLaks, they compile identically.

Ben Zotto also says it doesn't matter:

It's not faster. If you really care, compile with assembler output for your platform and look to see. It doesn't matter. This never matters. Write your infinite loops however you like.

In response to user1216838, here's my attempt to reproduce his results.

Here's my machine:

cat /etc/*-release
CentOS release 6.4 (Final)

gcc version:

Target: x86_64-unknown-linux-gnu
Thread model: posix
gcc version 4.8.2 (GCC)

And test files:

// testing.cpp
#include <iostream>

int main() {
    do { break; } while(1);
}

// testing2.cpp
#include <iostream>

int main() {
    while(1) { break; }
}

// testing3.cpp
#include <iostream>

int main() {
    while(true) { break; }
}

The commands:

gcc -S -o test1.asm testing.cpp
gcc -S -o test2.asm testing2.cpp
gcc -S -o test3.asm testing3.cpp

cmp test1.asm test2.asm

The only difference is the first line, aka the filename.

test1.asm test2.asm differ: byte 16, line 1

Output:

With -O3, the output is considerably smaller of course, but still no difference.

It is mentioned in the .data() documentation

The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)

This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?

The demo on my original answer below doesn't seem to work any more.

Updated answer

Again, from the .data() documentation

The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.

So for <div data-role="page"></div> the following is true $('div').data('role') === 'page'

I'm fairly sure that $('div').data('data-role') worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.

Updated demo (2015-07-25)

Also see jQuery Data vs Attr?

HTML

<div id="changeMe" data-key="luke" data-another-key="vader"></div>
<a href="#" id="changeData"></a>
<table id="log">
    <tr><th>Setter</th><th>Getter</th><th>Result of calling getter</th><th>Notes</th></tr>
</table>

JavaScript (jQuery 1.6.2+)

var $changeMe = $('#changeMe');
var $log = $('#log');

var logger;
(logger = function(setter, getter, note) {
    note = note || '';
    eval('$changeMe' + setter);
    var result = eval('$changeMe' + getter);
    $log.append('<tr><td><code>' + setter + '</code></td><td><code>' + getter + '</code></td><td>' + result + '</td><td>' + note + '</td></tr>');
})('', ".data('key')", "Initial value");

$('#changeData').click(function() {
    // set data-key to new value
    logger(".data('key', 'leia')", ".data('key')", "expect leia on jQuery node object but DOM stays as luke");
    // try and set data-key via .attr and get via some methods
    logger(".attr('data-key', 'yoda')", ".data('key')", "expect leia (still) on jQuery object but DOM now yoda");
    logger("", ".attr('key')", "expect undefined (no attr <code>key</code>)");
    logger("", ".attr('data-key')", "expect yoda in DOM and on jQuery object");

    // bonus points
    logger('', ".data('data-key')", "expect undefined (cannot get via this method)");
    logger(".data('anotherKey')", ".data('anotherKey')", "jQuery 1.6+ get multi hyphen <code>data-another-key</code>");
    logger(".data('another-key')", ".data('another-key')", "jQuery < 1.6 get multi hyphen <code>data-another-key</code> (also supported in jQuery 1.6+)");

    return false;
});

$('#changeData').click();

Older demo

Original answer

For this HTML:

<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>

and this JavaScript (with jQuery 1.6.2)

console.log($('#foo').data('helptext'));

$('#changeData').click(function() {
    $('#foo').data('helptext', 'Testing 123');
//  $('#foo').attr('data-helptext', 'Testing 123');
    console.log($('#foo').data('data-helptext'));
    return false;
});

See demo

Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123'); does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123'); does.

I'm using Firefox, and my working solution is very close to obysky. The only difference is that the method you call in an svg element will return multiple rects and you need to select the first one.

var chart = document.getElementsByClassName("chart")[0];
var width = chart.getClientRects()[0].width;
var height = chart.getClientRects()[0].height;

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/

You can easily raise an exception in a lambda, if that's what you really want to do.

def Raise(exception):
    raise exception
x = lambda y: 1 if y < 2 else Raise(ValueError("invalid value"))

Is this a good idea? My instinct in general is to leave the error reporting out of lambdas; let it have a value of None and raise the error in the caller. I don't think this is inherently evil, though--I consider the "y if x else z" syntax itself worse--just make sure you're not trying to stuff too much into a lambda body.

Webkit browsers like Safari and Chrome subtract the scroll bar width from the visible page width when calculating width: 100% or 100vw. More at DM Rutherford's Scrolling and Page Width.

Try using overflow-y: overlay instead.

No this is not the definition of scrum, it is the wikipedia excerpt on the definition of burnout.

Dont do too many short 10 days sprints. You will burnout your team eventually. Use short sprints where you really need them, and don't do too many in a row. Think long-term. A distance runner always paces themselves for the full race and does sprints in short distances only where it matters.

If you burnout your team you can toss out all them fancy scrum charts, they won't do a thing for your team's plummeting productivity.

Just as Oded has answered. You need to have this sort of detection functionality in javascript.

I've struggled with this myself and realized that the offset is not enough. It does not give you any information about daylight saving for example. I ended up writing some code to map to zoneinfo database keys.

By checking several dates around a year you can more accurately determine a timezone.

Try the script here: http://jsfiddle.net/pellepim/CsNcf/

Simply change your system timezone and click run to test it. If you are running chrome you need to do each test in a new tab though (and safar needs to be restarted to pick up timezone changes).

If you want more details of the code check out: https://bitbucket.org/pellepim/jstimezonedetect/

No, <!-- ... --> is the only comment syntax in HTML.

Some addition to previous comments: 'firstboot' won't be available until you run 'mount_root' command.

So here is a full recap of what needs to be done. All manipulations I did on Windows 8.1.

• Enter Failsafe mode (hold the reset button on boot for a few seconds)
• Assign a static IP address, 192.168.1.2, to your PC. Example of a command: netsh interface ip set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1
• Connect to address 192.168.1.1 from telnet (I use PuTTY) and login/password isn't required).
• Run 'mount_root' (otherwise 'firstboot' won't be available).
• Run 'firstboot' to reset.
• Run 'reboot -f' to reboot.

Now you can enter to the router console from a browser. Also don't forget to return your PC from static to DHCP address assignment. Example: netsh interface ip set address name="Ethernet" source=dhcp

Does your dump contain features that are not supported in your version of MySQL? You can also try to remove the starting (and ending) MySQL commented SET-statements.

I don't know if your dump comes from a Linux version of MySQL (line endings)?

for those who got here because the title of the question:

I use Reply-To: address with webforms. when someone fills out the form, the webpage sends an automatic email to the page's owner. the From: is the automatic mail sender's address, so the owner knows it is from the webform. but the Reply-To: address is the one filled in in the form by the user, so the owner can just hit reply to contact them.

Ideally these would go in a class called "FileNaming" or maybe just rename Encode to "FileNameEncode". Note: these are not designed to handle Full Paths, just the folder and/or file names. Ideally you would Split("/") your full path first and then check the pieces. And obviously instead of a union, you could just add the "%" character to the list of chars not allowed in Windows, but I think it's more helpful/readable/factual this way. Decode() is exactly the same but switches the Replace(Uri.HexEscape(s[0]), s) "escaped" with the character.

public static List<string> urlEncodedCharacters = new List<string>
{
  "/", "\\", "<", ">", ":", "\"", "|", "?", "%" //and others, but not *
};
//Since this is a superset of urlEncodedCharacters, we won't be able to only use UrlEncode() - instead we'll use HexEncode
public static List<string> specialCharactersNotAllowedInWindows = new List<string>
{
  "/", "\\", "<", ">", ":", "\"", "|", "?", "*" //windows dissallowed character set
};

    public static string Encode(string fileName)
    {

        return fileName;

Thanks @simon-tewsi for the very usefull table above!

If you are totally new to python read step by step or go directly to 5th step directly. Follow the below method to install scipy 0.18.1 on Windows 64-bit , Python 64-bit . Be careful with the versions of 1. Python 2. Windows 3. .whl version of numpy and scipy files 4. First install numpy and then scipy.

pip install FileName.whl

5. ForNumpy:http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy ForScipy:http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

Be aware of the file name ( what I mean is check the cp no). Ex :scipy-0.18.1-cp35-cp35m-win_amd64.whl To check which cp is supported by your pip , go to point No 2 below.

If you are using .whl file . Following errors are likely to occur .

1. You are using pip version 7.1.0, however version 8.1.2 is available.

You should consider upgrading via the 'python -m pip install --upgrade pip' command

2. scipy-0.15.1-cp33-none-win_amd64.whl.whl is not supported wheel on this platform

For the above error : start Python(in my case 3.5), type : import pip print(pip.pep425tags.get_supported())

output :

[('cp35', 'cp35m', 'win_amd64'), ('cp35', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'), ('cp35', 'none', 'any'), ('cp3', 'none', 'any'), ('py35', 'none', 'any'), ('py3', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]

In the output you will observe cp35 is there , so download cp35 for numpy as well as scipy. Further edits are most welcome !!!!

First, There is no such css-changes event out of the box, but you can create one by your own, as onchange is for :input elements only. not for css changes.

There are two ways to track css changes.

1. Examine the DOM element for css changes every x time(500 milliseconds in the example).
2. Trigger an event when you change the element css.
3. Use the DOMAttrModified mutation event. But it's deprecated, so I'll skip on it.

First way:

var $element = $("#elementId");
var lastHeight = $("#elementId").css('height');
function checkForChanges()
{
    if ($element.css('height') != lastHeight)
    {
        alert('xxx');
        lastHeight = $element.css('height'); 
    }

    setTimeout(checkForChanges, 500);
}

Second way:

$('#mainContent').bind('heightChange', function(){
        alert('xxx');
    });


$("#btnSample1").click(function() {
    $("#mainContent").css('height', '400px');
    $("#mainContent").trigger('heightChange'); //<====
    ...
});    

If you control the css changes, the second option is a lot more elegant and efficient way of doing it.

Documentations:

• bind: Description: Attach a handler to an event for the elements.
• trigger: Description: Execute all handlers and behaviors attached to the matched elements for the given event type.

{{ Form::open(array('action' => "WelcomeController@log_in")) }}
...
{{ Form::close() }}

Illegal XML Tag Name Characters can be encoded using Unicode UCS-2. This works very nicely. I am using it to create XML that gets turned into json (JPath is weak compared to XPath). Notice the handling of spaces, (, ) characters. Unicode UCS-2 Code Chart: http://www.columbia.edu/kermit/ucs2.html

        tag.Name = tag.Name.Replace(" ", "_x005F_x0020_");
        tag.Name = tag.Name.Replace("(", "_x005F_x0028_");
        tag.Name = tag.Name.Replace(")", "_x005F_x0029_");

XML:

  <Internal_x005F_x0020_Chargeback_x005F_x0020_ID>{CHARGEBACKCODE}</Internal_x005F_x0020_Chargeback_x005F_x0020_ID>
  <Bill_x005F_x0020_To>{CHARGEBACKCODE}</Bill_x005F_x0020_To>
  <Operator_x005F_x0020_or_x005F_x0020_Directly_x005F_x0020_Responsible_x005F_x0020_Individual_x005F_x0020__x005F_x0028_DRI_x005F_x0029_>[email protected]</Operator_x005F_x0020_or_x005F_x0020_Directly_x005F_x0020_Responsible_x005F_x0020_Individual_x005F_x0020__x005F_x0028_DRI_x005F_x0029_>

transformed to json via json.net:

    "Internal Chargeback ID": "{CHARGEBACKCODE}",
    "Bill To": "{CHARGEBACKCODE}",
    "Operator or Directly Responsible Individual (DRI)": "[email protected]",

Many of the answers discuss how many UUIDs would have to be generated to reach a 50% chance of a collision. But a 50%, 25%, or even 1% chance of collision is worthless for an application where collision must be (virtually) impossible.

Do programmers routinely dismiss as "impossible" other events that can and do occur?

When we write data to a disk or memory and read it back again, we take for granted that the data are correct. We rely on the device's error correction to detect any corruption. But the chance of undetected errors is actually around 2^-50.

Wouldn't it make sense to apply a similar standard to random UUIDs? If you do, you will find that an "impossible" collision is possible in a collection of around 100 billion random UUIDs (2^36.5).

This is an astronomical number, but applications like itemized billing in a national healthcare system, or logging high frequency sensor data on a large array of devices could definitely bump into these limits. If you are writing the next Hitchhiker's Guide to the Galaxy, don't try to assign UUIDs to each article!

We have just been going through this same issue, but the other way around. That is, we store dollar amounts as DECIMAL, but now we're finding that, for example, MySQL was calculating a value of 4.389999999993, but when storing this into the DECIMAL field, it was storing it as 4.38 instead of 4.39 like we wanted it to. So, though DOUBLE may cause rounding issues, it seems that DECIMAL can cause some truncating issues as well.

Or, if you know the width of the two "side" images and don't want to deal with floats:

<div class="container">
    <div class="left-panel"><img src="myleftimage" /></div>
    <div class="center-panel">Content goes here...</div>
    <div class="right-panel"><img src="myrightimage" /></div>
</div>

CSS:

.container {
    position:relative;
    padding-left:50px;
    padding-right:50px;
}

.container .left-panel {
    width: 50px;
    position:absolute;
    left:0px;
    top:0px;
}

.container .right-panel {
    width: 50px;
    position:absolute;
    right:0px;
    top:0px;
}

.container .center-panel {
    background: url('mymiddleimage');
}

Notes:

Position:relative on the parent div is used to make absolutely positioned children position themselves relative to that node.

You can easily pick image from asset without UIImage(named: "green-square-Retina").

Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.

See this Stackoverflow answer for reference.

My guess is the best you can come up with is

this.approved_by = IsNullOrEmpty(planRec.approved_by) ? string.Empty
                                                      : planRec.approved_by.ToString();

Of course since you're hinting at the fact that approved_by is an object (which cannot equal ""), this would be rewritten as

this.approved_by = (planRec.approved_by ?? string.Empty).ToString();

The difference is exactly what the name implies: a group by performs a grouping operation, and an order by sorts.

If you do SELECT * FROM Customers ORDER BY Name then you get the result list sorted by the customers name.

If you do SELECT IsActive, COUNT(*) FROM Customers GROUP BY IsActive you get a count of active and inactive customers. The group by aggregated the results based on the field you specified.

You can simply get the event object when you submit the form. From that, get the submitter object. As below:

$(".review-form").submit(function (e) {
        e.preventDefault(); // avoid to execute the actual submit of the form.

        let submitter_btn = $(e.originalEvent.submitter);
        
        console.log(submitter_btn.attr("name"));
}

In case you want to send this form to the backend, you can create a new form element by new FormData() and set the key-value pair for which button was pressed, then access it in the backend. Something like this -

$(".review-form").submit(function (e) {
        e.preventDefault(); // avoid to execute the actual submit of the form.

        let form = $(this);
        let newForm = new FormData($(form)[0]);
        let submitter_btn = $(e.originalEvent.submitter);
        
        console.log(submitter_btn.attr("name"));

        if (submitter_btn.attr("name") == "approve_btn") {
            newForm.set("action_for", submitter_btn.attr("name"));
        } else if (submitter_btn.attr("name") == "reject_btn") {
            newForm.set("action_for", submitter_btn.attr("name"));
        } else {
            console.log("there is some error!");
            return;
        }
}

I was basically trying to have a form where user can either approve or disapprove/ reject a product for further processes in a task. My HTML form is something like this -

<form method="POST" action="{% url 'tasks:review-task' taskid=product.task_id.id %}"
    class="review-form">
    {% csrf_token %}
    <input type="hidden" name="product_id" value="{{product.product_id}}" />
    <input type="hidden" name="task_id" value="{{product.task_id_id}}" />
    <button type="submit" name="approve_btn" class="btn btn-link" id="approve-btn">
        <i class="fa fa-check" style="color: rgb(63, 245, 63);"></i>
    </button>
    <button type="submit" name="reject_btn" class="btn btn-link" id="reject-btn">
            <i class="fa fa-times" style="color: red;"></i>
    </button>
</form>

Let me know if you have any doubts.

Go to the Properties of your dateTimePickerin Visual Studio and set Format to Custom. Under CustomFormat enter your format. In my case I used MMMMdd, yyyy | hh:mm

If you have the sqlite database, use the sqlite3 command line program and these commands:

To list all the tables in the database:

.tables

To show the schema for a given tablename:

.schema tablename

Two way to add Scroll in page

1. Using SingleChildScrollView :

     SingleChildScrollView(
          child: Column(
            children: [
              Container(....),
              SizedBox(...),
              Container(...),
              Text(....)
            ],
          ),
      ),

2. Using ListView : ListView is default provide Scroll no need to add extra widget for scrolling

     ListView(
          children: [
            Container(..),
            SizedBox(..),
            Container(...),
            Text(..)
          ],
      ),

for each S3ObjecrSummary in objectListing.getObjectSummaries()

it's looping through each item in the collection

You could descendingly order the tabele by id and limit the number of results to one:

SELECT id FROM tablename ORDER BY id DESC LIMIT 1

BUT: ORDER BY rearranges the entire table for this request. So if you have a lot of data and you need to repeat this operation several times, I would not recommend this solution.

I would fire up Visual Studio, create a web project (or console app - doesn't matter).

For .Net Standard:

1. I would right-click on the project and pick "Add Service Reference" from the Add context menu.
2. I would click on Advanced, then click on Add Service Reference.
3. I would get the complete file path of the wsdl and paste into the address bar. Then fire the Arrow (go button).
4. If there is an error trying to load the file, then there must be a broken and unresolved url the file needs to resolve as shown below: Refer to this answer for information on how to fix: Stackoverflow answer to: Unable to create service reference for wsdl file

If there is no error, you should simply set the NameSpace you want to use to access the service and it'll be generated for you.

For .Net Core

1. I would right click on the project and pick Connected Service from the Add context menu.
2. I would select Microsoft WCF Web Service Reference Provider from the list.
3. I would press browse and select the wsdl file straight away, Set the namespace and I am good to go. Refer to the error fix url above if you encounter any error.

Any of the methods above will generate a simple, very basic WCF client for you to use. You should find a "YourservicenameClient" class in the generated code.

For reference purpose, the generated cs file can be found in your Obj/debug(or release)/XsdGeneratedCode and you can still find the dlls in the TempPE folder.

The created Service(s) should have methods for each of the defined methods on the WSDL contract.

Instantiate the client and call the methods you want to call - that's all there is!

YourServiceClient client = new YourServiceClient();
client.SayHello("World!");

If you need to specify the remote URL (not using the one created by default), you can easily do this in the constructor of the proxy client:

YourServiceClient client = new YourServiceClient("configName", "remoteURL");

where configName is the name of the endpoint to use (you will use all the settings except the URL), and the remoteURL is a string representing the URL to connect to (instead of the one contained in the config).

In the step 5 of Phil, "Resources" is no longer available in the new version of the Chrome. You need to click the page icon just beside the Ajax page listed in the bottom pane with the columns of Name, Method, Status, ...

Then it will show you more panels where you will find the error messages.

If HTML and use bootstrap they have a helper class.

<span class="text-nowrap">1-866-566-7233</span>

I met this discussion looking for some details on the sudo implementation in different operating systems. Reading it I found that the solution by @brian-white (https://stackoverflow.com/a/42956057/3627676) is useful but can be improved slightly. I avoided creating the temporary file and implemented to execute everything by the single script.

Also I investigated the next step of the improvement to output within the single window/console. Unfortunately, without any success. I tried to use named pipes to capture STDOUT/STDERR and print in the main window. But child process didn't write to named pipes. However writing to a regular file works well.

I dropped any attempts to find the root cause and left the current solution as is. Hope my post can be useful as well.

Improvements:

• no temporary file
• no parsing and reconstructing the command line options
• wait the elevated command
• use mintty or bash, if the first one not found
• return the command exit code

    #!/bin/bash

    # Being Administrators, invoke the command directly
    id -G | grep -qw 544 && {
        "$@"
        exit $?
    }

    # The CYG_SUDO variable is used to control the command invocation
    [ -z "$CYG_SUDO" ] && {
        mintty="$( which mintty 2>/dev/null )"
        export CYG_SUDO="$$"
        cygstart --wait --action=runas $mintty /bin/bash "$0" "$@"
        exit $?
    }

    # Now we are able to:
    # -- launch the command
    # -- display the message
    # -- return the exit code
    "$@"
    RETVAL=$?

    echo "$0: Press  to close window..."
    read

    exit $RETVAL

It's also important to realize that simply moving the program break pointer around with brk and sbrk doesn't actually allocate the memory, it just sets up the address space. On Linux, for example, the memory will be "backed" by actual physical pages when that address range is accessed, which will result in a page fault, and will eventually lead to the kernel calling into the page allocator to get a backing page.
