The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

If you were open to using JQuery, you could modify the background color for any link that has the property aria-expanded set to true by doing the following...

$("a[aria-expanded='true']").css("background-color", "#42DCA3");

Depending on how specific you want to be regarding which links this applies to, you may have to slightly modify your selector.

Here is directive from the official examples angular docs v1.5 that shows how to compile html:

.directive('compileHtml', function ($compile) {
  return function (scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compileHtml);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
    );
  };
});

Usage:

<div compile-html="item.htmlString"></div>

It will insert item.htmlString property as html any place, like

<li ng-repeat="item in itemList">
    <div compile-html="item.htmlString"></div>

The second clause does not need a !variable.nil? check—if evaluation reaches that point, variable.nil is guaranteed to be false (because of short-circuiting).

This should be sufficient:

variable = id if variable.nil? || variable.empty?

If you're working with Ruby on Rails, Object.blank? solves this exact problem:

An object is blank if it’s false, empty, or a whitespace string. For example, "", " ", nil, [], and {} are all blank.

I would use DBA_SOURCE (if you have access to it) because if the object you require is not owned by the schema under which you are logged in you will not see it.

If you need to know the functions and Procs inside the packages try something like this:

select * from all_source
 where type = 'PACKAGE'
   and (upper(text) like '%FUNCTION%' or upper(text) like '%PROCEDURE%')
   and owner != 'SYS';

The last line prevents all the sys stuff (DBMS_ et al) from being returned. This will work in user_source if you just want your own schema stuff.

Following @Aravind's answer with more details

@RequestMapping("/myPath.htm")
public ModelAndView add(HttpServletRequest request, HttpServletResponse response) throws Exception{
    myServiceMethodSettingCookie(request, response);        //Do service call passing the response
    return new ModelAndView("CustomerAddView");
}

// service method
void myServiceMethodSettingCookie(HttpServletRequest request, HttpServletResponse response){
    final String cookieName = "my_cool_cookie";
    final String cookieValue = "my cool value here !";  // you could assign it some encoded value
    final Boolean useSecureCookie = false;
    final int expiryTime = 60 * 60 * 24;  // 24h in seconds
    final String cookiePath = "/";

    Cookie cookie = new Cookie(cookieName, cookieValue);

    cookie.setSecure(useSecureCookie);  // determines whether the cookie should only be sent using a secure protocol, such as HTTPS or SSL

    cookie.setMaxAge(expiryTime);  // A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

    cookie.setPath(cookiePath);  // The cookie is visible to all the pages in the directory you specify, and all the pages in that directory's subdirectories

    response.addCookie(cookie);
}

Most Java projects often have apache-commons lang available. StringUtils.join() methods is very nice and has several flavors to meet almost every need.

public static java.lang.String join(java.util.Collection collection,
                                    char separator)


public static String join(Iterator iterator, String separator) {
    // handle null, zero and one elements before building a buffer 
    Object first = iterator.next();
    if (!iterator.hasNext()) {
        return ObjectUtils.toString(first);
    }
    // two or more elements 
    StringBuffer buf = 
        new StringBuffer(256); // Java default is 16, probably too small 
    if (first != null) {
        buf.append(first);
    }
    while (iterator.hasNext()) {
        if (separator != null) {
            buf.append(separator);
        }
        Object obj = iterator.next();
        if (obj != null) {
            buf.append(obj);
        }
    }
    return buf.toString();
}

Parameters:

collection - the Collection of values to join together, may be null

separator - the separator character to use

Returns: the joined String, null if null iterator input

Since: 2.3

You can use it this way

Card(
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(15.0),
  ),
  child: Text(
    'Card with circular border',
    textScaleFactor: 1.2,
  ),
),
Card(
  shape: BeveledRectangleBorder(
    borderRadius: BorderRadius.circular(10.0),
  ),
  child: Text(
    'Card with Beveled border',
    textScaleFactor: 1.2,
  ),
),
Card(
  shape: StadiumBorder(
  side: BorderSide(
    color: Colors.black,
    width: 2.0,
  ),
),
  child: Text(
    'Card with Beveled border',
    textScaleFactor: 1.2,
  ),
),

Default values should start from the year 1000.

For example,

ALTER TABLE mytable last_active DATETIME DEFAULT '1000-01-01 00:00:00'

Hope this helps someone.

I had the same problem when trying to run a PowerShell script that only looked at a remote server to read the size of a hard disk.

I turned off the Firewall (Domain networks, Private networks, and Guest or public network) on the remote server and the script worked.

I then turned the Firewall for Domain networks back on, and it worked.

I then turned the Firewall for Private network back on, and it also worked.

I then turned the Firewall for Guest or public networks, and it also worked.

I had a similar problem when running a spring web application in an Eclipse managed tomcat. I solved this problem by adding maven dependencies in the project's web deployment assembly.

1. Open the project's properties (e.g., right-click on the project's name in the project explorer and select "Properties").
2. Select "Deployment Assembly".
3. Click the "Add..." button on the right margin.
4. Select "Java Build Path Entries" from the menu of Directive Type and click "Next".
5. Select "Maven Dependencies" from the Java Build Path Entries menu and click "Finish".

You should see "Maven Dependencies" added to the Web Deployment Assembly definition.

You can use strcpy but remember to end the array with '\0'

char array[20]; char string[100];

array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; array[5]='\0';
strcpy(string, array);
printf("%s\n", string);

Example with img tag but without background-image

This solution retains the img tag so that we do not lose the ability to drag or right-click to save the image but without background-image just center and crop with css.

Maintain the aspect ratio fine except in very hight images. (check the link)

(view in action)

Markup

<div class="center-cropped">
    <img src="http://placehold.it/200x150" alt="" />
</div>

? CSS

div.center-cropped {
  width: 100px;
  height: 100px;
  overflow:hidden;
}
div.center-cropped img {
  height: 100%;
  min-width: 100%;
  left: 50%;
  position: relative;
  transform: translateX(-50%);
}

None of the solutions in Intellij is as elegant (or useful) as in Eclipse. What we need is feature request to the intellij so that we can add a hook (what actions to perform) when the IDE autosaves.

In Eclipse we can add "post-save" actions, such as organize imports and format the class. Yes you have to do a "save" or ctrl-s but the hook is very convenient.

This answer was made pre-JPA2 implementations, if you're using JPA2, see the ElementCollection answer above:

Lists of objects inside a model object are generally considered "OneToMany" relationships with another object. However, a String is not (by itself) an allowable client of a One-to-Many relationship, as it doesn't have an ID.

So, you should convert your list of Strings to a list of Argument-class JPA objects containing an ID and a String. You could potentially use the String as the ID, which would save a little space in your table both from removing the ID field and by consolidating rows where the Strings are equal, but you would lose the ability to order the arguments back into their original order (as you didn't store any ordering information).

Alternatively, you could convert your list to @Transient and add another field (argStorage) to your class that is either a VARCHAR() or a CLOB. You'll then need to add 3 functions: 2 of them are the same and should convert your list of Strings into a single String (in argStorage) delimited in a fashion that you can easily separate them. Annotate these two functions (that each do the same thing) with @PrePersist and @PreUpdate. Finally, add the third function that splits the argStorage into the list of Strings again and annotate it @PostLoad. This will keep your CLOB updated with the strings whenever you go to store the Command, and keep the argStorage field updated before you store it to the DB.

I still suggest doing the first case. It's good practice for real relationships later.

The accepted answer gives an example of using the newest file in a command and then exiting. If you need to do this in a bat file with other complex operations you can use the following to store the file name of the newest file in a variable:

FOR /F "delims=|" %%I IN ('DIR "*.*" /B /O:D') DO SET NewestFile=%%I

Now you can reference %NewestFile% throughout the rest of your bat file.

For example here is what we use to get the latest version of a database .bak file from a directory, copy it to a server, and then restore the db:

:Variables
SET DatabaseBackupPath=\\virtualserver1\Database Backups

echo.
echo Restore WebServer Database
FOR /F "delims=|" %%I IN ('DIR "%DatabaseBackupPath%\WebServer\*.bak" /B /O:D') DO SET NewestFile=%%I
copy "%DatabaseBackupPath%\WebServer\%NewestFile%" "D:\"

sqlcmd -U <username> -P <password> -d master -Q ^
"RESTORE DATABASE [ExampleDatabaseName] ^
FROM  DISK = N'D:\%NewestFile%' ^
WITH  FILE = 1,  ^
MOVE N'Example_CS' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Example.mdf',  ^
MOVE N'Example_CS_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Example_1.LDF',  ^
NOUNLOAD,  STATS = 10"

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

Actually, RESULT contains what you want — to demonstrate:

echo "$RESULT"

What you show is what you get from:

echo $RESULT

As noted in the comments, the difference is that (1) the double-quoted version of the variable (echo "$RESULT") preserves internal spacing of the value exactly as it is represented in the variable — newlines, tabs, multiple blanks and all — whereas (2) the unquoted version (echo $RESULT) replaces each sequence of one or more blanks, tabs and newlines with a single space. Thus (1) preserves the shape of the input variable, whereas (2) creates a potentially very long single line of output with 'words' separated by single spaces (where a 'word' is a sequence of non-whitespace characters; there needn't be any alphanumerics in any of the words).

Online tools to translate Apache .htaccess to Nginx rewrite tools include:

• http://winginx.com/htaccess
• http://www.anilcetin.com/convert-apache-htaccess-to-nginx/

Note that these tools will convert to equivalent rewrite expressions using if statements, but they should be converted to try_files. See:

The documentation is not very clear about AngularJS routing. It talks about Hashbang and HTML5 mode. In fact, AngularJS routing operates in three modes:

• Hashbang Mode
• HTML5 Mode
• Hashbang in HTML5 Mode

For each mode there is a a respective LocationUrl class (LocationHashbangUrl, LocationUrl and LocationHashbangInHTML5Url).

In order to simulate URL rewriting you must actually set html5mode to true and decorate the $sniffer class as follows:

$provide.decorator('$sniffer', function($delegate) {
  $delegate.history = false;
  return $delegate;
});

I will now explain this in more detail:

Hashbang Mode

Configuration:

$routeProvider
  .when('/path', {
    templateUrl: 'path.html',
});
$locationProvider
  .html5Mode(false)
  .hashPrefix('!');

This is the case when you need to use URLs with hashes in your HTML files such as in

<a href="index.html#!/path">link</a>

In the Browser you must use the following Link: http://www.example.com/base/index.html#!/base/path

As you can see in pure Hashbang mode all links in the HTML files must begin with the base such as "index.html#!".

HTML5 Mode

Configuration:

$routeProvider
  .when('/path', {
    templateUrl: 'path.html',
  });
$locationProvider
  .html5Mode(true);

You should set the base in HTML-file

<html>
  <head>
    <base href="/">
  </head>
</html>

In this mode you can use links without the # in HTML files

<a href="/path">link</a>

Link in Browser:

http://www.example.com/base/path

Hashbang in HTML5 Mode

This mode is activated when we actually use HTML5 mode but in an incompatible browser. We can simulate this mode in a compatible browser by decorating the $sniffer service and setting history to false.

Configuration:

$provide.decorator('$sniffer', function($delegate) {
  $delegate.history = false;
  return $delegate;
});
$routeProvider
  .when('/path', {
    templateUrl: 'path.html',
  });
$locationProvider
  .html5Mode(true)
  .hashPrefix('!');

Set the base in HTML-file:

<html>
  <head>
    <base href="/">
  </head>
</html>

In this case the links can also be written without the hash in the HTML file

<a href="/path">link</a>

Link in Browser:

http://www.example.com/index.html#!/base/path

First, get Pdftk:

sudo apt-get install pdftk

Now, as shown on example page, use

pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf

for merging pdf files into one.

This may not be the best way for MVC ( https://stackoverflow.com/a/9461386/5869805 )

Below is how you render a view in Application_Error and write it to http response. You do not need to use redirect. This will prevent a second request to server, so the link in browser's address bar will stay same. This may be good or bad, it depends on what you want.

Global.asax.cs

protected void Application_Error()
{
    var exception = Server.GetLastError();
    // TODO do whatever you want with exception, such as logging, set errorMessage, etc.
    var errorMessage = "SOME FRIENDLY MESSAGE";

    // TODO: UPDATE BELOW FOUR PARAMETERS ACCORDING TO YOUR ERROR HANDLING ACTION
    var errorArea = "AREA";
    var errorController = "CONTROLLER";
    var errorAction = "ACTION";
    var pathToViewFile = $"~/Areas/{errorArea}/Views/{errorController}/{errorAction}.cshtml"; // THIS SHOULD BE THE PATH IN FILESYSTEM RELATIVE TO WHERE YOUR CSPROJ FILE IS!

    var requestControllerName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["controller"]);
    var requestActionName = Convert.ToString(HttpContext.Current.Request.RequestContext?.RouteData?.Values["action"]);

    var controller = new BaseController(); // REPLACE THIS WITH YOUR BASE CONTROLLER CLASS
    var routeData = new RouteData { DataTokens = { { "area", errorArea } }, Values = { { "controller", errorController }, {"action", errorAction} } };
    var controllerContext = new ControllerContext(new HttpContextWrapper(HttpContext.Current), routeData, controller);
    controller.ControllerContext = controllerContext;

    var sw = new StringWriter();
    var razorView = new RazorView(controller.ControllerContext, pathToViewFile, "", false, null);
    var model = new ViewDataDictionary(new HandleErrorInfo(exception, requestControllerName, requestActionName));
    var viewContext = new ViewContext(controller.ControllerContext, razorView, model, new TempDataDictionary(), sw);
    viewContext.ViewBag.ErrorMessage = errorMessage;
    //TODO: add to ViewBag what you need
    razorView.Render(viewContext, sw);
    HttpContext.Current.Response.Write(sw);
    Server.ClearError();
    HttpContext.Current.Response.End(); // No more processing needed (ex: by default controller/action routing), flush the response out and raise EndRequest event.
}

View

@model HandleErrorInfo
@{
    ViewBag.Title = "Error";
    // TODO: SET YOUR LAYOUT
}
<div class="">
    ViewBag.ErrorMessage
</div>
@if(Model != null && HttpContext.Current.IsDebuggingEnabled)
{
    <div class="" style="background:khaki">
        <p>
            <b>Exception:</b> @Model.Exception.Message <br/>
            <b>Controller:</b> @Model.ControllerName <br/>
            <b>Action:</b> @Model.ActionName <br/>
        </p>
        <div>
            <pre>
                @Model.Exception.StackTrace
            </pre>
        </div>
    </div>
}

Read your error carefully-./src/App.js Module not found: Can't resolve './src/components/header/header' in '/home/wiseman/Desktop/React_Components/github-portfolio/src'

just write- ./header/header instead ./src/components/header/header in App.js

if it doesnt work try to change header file name may be head

This is my experience

 .navbar { min-height:38px;   }
 .navbar .navbar-brand{ padding: 0 12px;font-size: 16px;line-height: 38px;height: 38px; }
 .navbar .navbar-nav > li > a {  padding-top: 0px; padding-bottom: 0px; line-height: 38px; }
 .navbar .navbar-toggle {  margin-top: 3px; margin-bottom: 0px; padding: 8px 9px; }
 .navbar .navbar-form { margin-top: 2px; margin-bottom: 0px }
 .navbar .navbar-collapse {border-color: #A40303;}

Read it backwards (as driven by Clockwise/Spiral Rule):

• int* - pointer to int
• int const * - pointer to const int
• int * const - const pointer to int
• int const * const - const pointer to const int

Now the first const can be on either side of the type so:

• const int * == int const *
• const int * const == int const * const

If you want to go really crazy you can do things like this:

• int ** - pointer to pointer to int
• int ** const - a const pointer to a pointer to an int
• int * const * - a pointer to a const pointer to an int
• int const ** - a pointer to a pointer to a const int
• int * const * const - a const pointer to a const pointer to an int
• ...

And to make sure we are clear on the meaning of const:

int a = 5, b = 10, c = 15;

const int* foo;     // pointer to constant int.
foo = &a;           // assignment to where foo points to.

/* dummy statement*/
*foo = 6;           // the value of a can´t get changed through the pointer.

foo = &b;           // the pointer foo can be changed.



int *const bar = &c;  // constant pointer to int 
                      // note, you actually need to set the pointer 
                      // here because you can't change it later ;)

*bar = 16;            // the value of c can be changed through the pointer.    

/* dummy statement*/
bar = &a;             // not possible because bar is a constant pointer.           

foo is a variable pointer to a constant integer. This lets you change what you point to but not the value that you point to. Most often this is seen with C-style strings where you have a pointer to a const char. You may change which string you point to but you can't change the content of these strings. This is important when the string itself is in the data segment of a program and shouldn't be changed.

bar is a constant or fixed pointer to a value that can be changed. This is like a reference without the extra syntactic sugar. Because of this fact, usually you would use a reference where you would use a T* const pointer unless you need to allow NULL pointers.

You can use below code to get the Active Sheet name and change it to yours preferred name.

Sub ChangeSheetName()

Dim shName As String
Dim currentName As String
currentName = ActiveSheet.Name
shName = InputBox("What name you want to give for your sheet")
ThisWorkbook.Sheets(currentName).Name = shName

End Sub

You can use only junit-jupiter as a test dependency instead of junit-jupiter-api, junit-platform-launcher, junit-jupiter-engine.

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>5.5.2</version>
    <scope>test</scope>
</dependency>

#The Best way is to use `fStrings` (very easy and powerful in python3)   
#Format: f'your-string'   
#For Example:

mylist=['laks',444,'M']

cursor.execute(f'INSERT INTO mytable VALUES ("{mylist[0]}","{mylist[1]}","{mylist[2]}")')

#THATS ALL!! EASY!!
#You can use it with for loop!

PHP 5 has the RecursiveDirectoryIterator.

The manual has a basic example:

<?php

$directory = '/system/infomation/';

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

while($it->valid()) {

    if (!$it->isDot()) {

        echo 'SubPathName: ' . $it->getSubPathName() . "\n";
        echo 'SubPath:     ' . $it->getSubPath() . "\n";
        echo 'Key:         ' . $it->key() . "\n\n";
    }

    $it->next();
}

?>

Edit -- Here's a slightly more advanced example (only slightly) which produces output similar to what you want (i.e. folder names then files).

// Create recursive dir iterator which skips dot folders
$dir = new RecursiveDirectoryIterator('./system/information',
    FilesystemIterator::SKIP_DOTS);

// Flatten the recursive iterator, folders come before their files
$it  = new RecursiveIteratorIterator($dir,
    RecursiveIteratorIterator::SELF_FIRST);

// Maximum depth is 1 level deeper than the base folder
$it->setMaxDepth(1);

// Basic loop displaying different messages based on file or folder
foreach ($it as $fileinfo) {
    if ($fileinfo->isDir()) {
        printf("Folder - %s\n", $fileinfo->getFilename());
    } elseif ($fileinfo->isFile()) {
        printf("File From %s - %s\n", $it->getSubPath(), $fileinfo->getFilename());
    }
}

I know I'm a bit late to this, but in case you wanted to perform relative padding (aka edge padding), here's how you can implement it. Note that the very first instance of assignment results in zero-padding, so you can use this for both zero-padding and relative padding (this is where you copy the edge values of the original array into the padded array).

def replicate_padding(arr):
    """Perform replicate padding on a numpy array."""
    new_pad_shape = tuple(np.array(arr.shape) + 2) # 2 indicates the width + height to change, a (512, 512) image --> (514, 514) padded image.
    padded_array = np.zeros(new_pad_shape) #create an array of zeros with new dimensions
    
    # perform replication
    padded_array[1:-1,1:-1] = arr        # result will be zero-pad
    padded_array[0,1:-1] = arr[0]        # perform edge pad for top row
    padded_array[-1, 1:-1] = arr[-1]     # edge pad for bottom row
    padded_array.T[0, 1:-1] = arr.T[0]   # edge pad for first column
    padded_array.T[-1, 1:-1] = arr.T[-1] # edge pad for last column
    
    #at this point, all values except for the 4 corners should have been replicated
    padded_array[0][0] = arr[0][0]     # top left corner
    padded_array[-1][0] = arr[-1][0]   # bottom left corner
    padded_array[0][-1] = arr[0][-1]   # top right corner 
    padded_array[-1][-1] = arr[-1][-1] # bottom right corner

    return padded_array

Complexity Analysis:

The optimal solution for this is numpy's pad method. After averaging for 5 runs, np.pad with relative padding is only 8% better than the function defined above. This shows that this is fairly an optimal method for relative and zero-padding padding.

#My method, replicate_padding
start = time.time()
padded = replicate_padding(input_image)
end = time.time()
delta0 = end - start

#np.pad with edge padding
start = time.time()
padded = np.pad(input_image, 1, mode='edge')
end = time.time()
delta = end - start


print(delta0) # np Output: 0.0008790493011474609 
print(delta)  # My Output: 0.0008130073547363281
print(100*((delta0-delta)/delta)) # Percent difference: 8.12316715542522%

In the spring boot reference,it said:

When a class doesn’t include a package declaration it is considered to be in the “default package”. The use of the “default package” is generally discouraged, and should be avoided. It can cause particular problems for Spring Boot applications that use @ComponentScan, @EntityScan or @SpringBootApplication annotations, since every class from every jar, will be read.

com
 +- example
     +- myproject
         +- Application.java

In your cases. You must add scanBasePackages in the @SpringBootApplication annotation.just like@SpringBootApplication(scanBasePackages={"domain","contorller"..})

I couldn't find any major points on JetBrains' website and even Google didn't help that much.

You should train your search-fu twice as harder.

NOTE: PhpStorm includes all the functionality of WebStorm (HTML/CSS Editor, JavaScript Editor) and adds full-fledged support for PHP and Databases/SQL.

Their forum also has quite few answers for such question.

Basically: PhpStorm = WebStorm + PHP + Database support

WebStorm comes with certain (mainly) JavaScript oriented plugins bundled by default while they need to be installed manually in PhpStorm (if necessary).

At the same time: plugins that require PHP support would not be able to install in WebStorm (for obvious reasons).

P.S. Since WebStorm has different release cycle than PhpStorm, it can have new JS/CSS/HTML oriented features faster than PhpStorm (it's all about platform builds used).

For example: latest stable PhpStorm is v7.1.4 while WebStorm is already on v8.x. But, PhpStorm v8 will be released in approximately 1 month (accordingly to their road map), which means that stable version of PhpStorm will include some of the features that will only be available in WebStorm v9 (quite few months from now, lets say 2-3-5) -- if using/comparing stable versions ONLY.

UPDATE (2016-12-13): Since 2016.1 version PhpStorm and WebStorm use the same version/build numbers .. so there is no longer difference between the same versions: functionality present in WebStorm 2016.3 is the same as in PhpStorm 2016.3 (if the same plugins are installed, of course).

Everything that I know atm. is that PHPStorm doesn't support JS part like Webstorm

That's not correct (your wording). Missing "extra" technology in PhpStorm (for example: node, angularjs) does not mean that basic JavaScript support has missing functionality. Any "extras" can be easily installed (or deactivated, if not required).

UPDATE (2016-12-13): Here is the list of plugins that are bundled with WebStorm 2016.3 but require manual installation in PhpStorm 2016.3 (if you need them, of course):

• Cucumber.js
• Dart
• EditorConfig
• EJS
• Handelbars/Mustache
• Java Server Pages (JSP) Integration
• Karma
• LiveEdit
• Meteor
• PhoneGap/Cordova Plugin
• Polymer & Web Components
• Pug (ex-Jade)
• Spy-js
• Stylus support
• Yeoman

assertEquals uses the equals method for comparison. There is a different assert, assertSame, which uses the == operator.

To understand why == shouldn't be used with strings you need to understand what == does: it does an identity check. That is, a == b checks to see if a and b refer to the same object. It is built into the language, and its behavior cannot be changed by different classes. The equals method, on the other hand, can be overridden by classes. While its default behavior (in the Object class) is to do an identity check using the == operator, many classes, including String, override it to instead do an "equivalence" check. In the case of String, instead of checking if a and b refer to the same object, a.equals(b) checks to see if the objects they refer to are both strings that contain exactly the same characters.

Analogy time: imagine that each String object is a piece of paper with something written on it. Let's say I have two pieces of paper with "Foo" written on them, and another with "Bar" written on it. If I take the first two pieces of paper and use == to compare them it will return false because it's essentially asking "are these the same piece of paper?". It doesn't need to even look at what's written on the paper. The fact that I'm giving it two pieces of paper (rather than the same one twice) means it will return false. If I use equals, however, the equals method will read the two pieces of paper and see that they say the same thing ("Foo"), and so it'll return true.

The bit that gets confusing with Strings is that the Java has a concept of "interning" Strings, and this is (effectively) automatically performed on any string literals in your code. This means that if you have two equivalent string literals in your code (even if they're in different classes) they'll actually both refer to the same String object. This makes the == operator return true more often than one might expect.

Root certificates issued by CAs are just self-signed certificates (which may in turn be used to issue intermediate CA certificates). They have not much special about them, except that they've managed to be imported by default in many browsers or OS trust anchors.

While browsers and some tools are configured to look for the trusted CA certificates (some of which may be self-signed) in location by default, as far as I'm aware the openssl command isn't.

As such, any server that presents the full chain of certificate, from its end-entity certificate (the server's certificate) to the root CA certificate (possibly with intermediate CA certificates) will have a self-signed certificate in the chain: the root CA.

openssl s_client -connect myweb.com:443 -showcerts doesn't have any particular reason to trust Verisign's root CA certificate, and because it's self-signed you'll get "self signed certificate in certificate chain".

If your system has a location with a bundle of certificates trusted by default (I think /etc/pki/tls/certs on RedHat/Fedora and /etc/ssl/certs on Ubuntu/Debian), you can configure OpenSSL to use them as trust anchors, for example like this:

openssl s_client -connect myweb.com:443 -showcerts -CApath /etc/ssl/certs

From http://www.sqlite.org/lang_createtable.html:

CREATE TABLE IF NOT EXISTS some_table (id INTEGER PRIMARY KEY AUTOINCREMENT, ...);

The fundamental issue with your code is that you mix two APIs. Unfortunately online resources are not great at pointing this out, but there are two semaphore APIs on UNIX-like systems:

• POSIX IPC API, which is a standard API
• System V API, which is coming from the old Unix world, but practically available almost all Unix systems

Looking at the code above you used semget() from the System V API and tried to post through sem_post() which comes from the POSIX API. It is not possible to mix them.

To decide which semaphore API you want you don't have so many great resources. The simple best is the "Unix Network Programming" by Stevens. The section that you probably interested in is in Vol #2.

These two APIs are surprisingly different. Both support the textbook style semaphores but there are a few good and bad points in the System V API worth mentioning:

• it builds on semaphore sets, so once you created an object with semget() that is a set of semaphores rather then a single one
• the System V API allows you to do atomic operations on these sets. so you can modify or wait for multiple semaphores in a set
• the SysV API allows you to wait for a semaphore to reach a threshold rather than only being non-zero. waiting for a non-zero threshold is also supported, but my previous sentence implies that
• the semaphore resources are pretty limited on every unixes. you can check these with the 'ipcs' command
• there is an undo feature of the System V semaphores, so you can make sure that abnormal program termination doesn't leave your semaphores in an undesired state

Use android.util.Log and the static methods defined there (e.g., e(), w()).

result = db.engine.execute(text("<sql here>"))

executes the <sql here> but doesn't commit it unless you're on autocommit mode. So, inserts and updates wouldn't reflect in the database.

To commit after the changes, do

result = db.engine.execute(text("<sql here>").execution_options(autocommit=True))

In my opinion one of the worst chosen word's to describe the process, as it is not related to anything in real-life or similar. In general the word "queue" is very bad as if pronounced, it sounds like the English character "q". See the inefficiency here?

enqueue: to place something into a queue; to add an element to the tail of a queue;

dequeue to take something out of a queue; to remove the first available element from the head of a queue

source: https://www.thefreedictionary.com

How about:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    row.parentNode.removeChild(row);
}

And, if that fails, this should really work:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    var table = row.parentNode;
    while ( table && table.tagName != 'TABLE' )
        table = table.parentNode;
    if ( !table )
        return;
    table.deleteRow(row.rowIndex);
}

Because there might be a standard way you want to instantiate data in the abstract class. That way you can have classes that inherit from that class call the base constructor.

public abstract class A{

    private string data;

    protected A(string myString){
      data = myString;
    }

}

public class B : A {

     B(string myString) : base(myString){}

}

Well, PHP can do this easily.

It can be done with the PHP mail() function. Here's what a simple function would look like:

<?php     
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail function';
$headers = 'From: [email protected]';
mail($to_email,$subject,$message,$headers);
?>

This will send a background e-mail to the recipient specified in the $to_email.

The above example uses hard coded values in the source code for the email address and other details for simplicity.

Let’s assume you have to create a contact us form for users fill in the details and then submit.

1. Users can accidently or intentional inject code in the headers which can result in sending spam mail
2. To protect your system from such attacks, you can create a custom function that sanitizes and validates the values before the mail is sent.

Let’s create a custom function that validates and sanitizes the email address using the filter_var() built in function.

Here's an example code:

<?php 
function sanitize_my_email($field) {
    $field = filter_var($field, FILTER_SANITIZE_EMAIL);
    if (filter_var($field, FILTER_VALIDATE_EMAIL)) {
        return true;
    } else {
        return false;
    }
}
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail ';
$headers = 'From: [email protected]';
//check if the email address is invalid $secure_check
$secure_check = sanitize_my_email($to_email);
if ($secure_check == false) {
    echo "Invalid input";
} else { //send email 
    mail($to_email, $subject, $message, $headers);
    echo "This email is sent using PHP Mail";
}
?>

We will now let this be a separate PHP file, for example sendmail.php.

Then, will use this file on form submission, using the action attribute of the form, like:

<form action="sendmail.php" method="post">
   <input type="text" value="Your Name: ">
   <input type="password" value="Set Up A Passworrd">
   <input type="submit" value="Signup">
   <input type="reset" value="Reset Form">
</form>

Hope I could help

Dictionaries aren't really meant to work like this, because while uniqueness of keys is guaranteed, uniqueness of values isn't. So e.g. if you had

var greek = new Dictionary<int, string> { { 1, "Alpha" }, { 2, "Alpha" } };

What would you expect to get for greek.WhatDoIPutHere("Alpha")?

Therefore you can't expect something like this to be rolled into the framework. You'd need your own method for your own unique uses---do you want to return an array (or IEnumerable<T>)? Do you want to throw an exception if there are multiple keys with the given value? What about if there are none?

Personally I'd go for an enumerable, like so:

IEnumerable<TKey> KeysFromValue<TKey, TValue>(this Dictionary<TKey, TValue> dict, TValue val)
{
    if (dict == null)
    {
        throw new ArgumentNullException("dict");
    }
    return dict.Keys.Where(k => dict[k] == val);
}

var keys = greek.KeysFromValue("Beta");
int exceptionIfNotExactlyOne = greek.KeysFromValue("Beta").Single();

if someone is running Eclipse in Ubuntu and have this problem I have found the answer by following these steps:

1. Eclipse->window->preference.
2. Select installed JREs->Add
3. Select standardVM.
4. JRE home: press [Directory..] button.
5. Choose your java (my problem was my eclipse was running with java8 and my VM were with java7), in my case java8 was installed in usr/local/jvm/java-8-oracle.
6. Press finish.
7. Then press installed JRES arrow so you can see the other options.
8. Go to Execution Environment.
9. Select JavaSE-1.6 on left and in the right (the compatible JRE) you have to choose the Java you have just installed( in my case java-8-oracle). you have to do this steps with JavaSE1.8.
10. Click OK and restart Eclipse.

You are encoding to UTF-8, then re-encoding to UTF-8. Python can only do this if it first decodes again to Unicode, but it has to use the default ASCII codec:

>>> u'ñ'
u'\xf1'
>>> u'ñ'.encode('utf8')
'\xc3\xb1'
>>> u'ñ'.encode('utf8').encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Don't keep encoding; leave encoding to UTF-8 to the last possible moment instead. Concatenate Unicode values instead.

You can use str.join() (or, rather, unicode.join()) here to concatenate the three values with dashes in between:

nombre = u'-'.join(fabrica, sector, unidad)
return nombre.encode('utf-8')

but even encoding here might be too early.

Rule of thumb: decode the moment you receive the value (if not Unicode values supplied by an API already), encode only when you have to (if the destination API does not handle Unicode values directly).

Exported variables such as $HOME and $PATH are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.

$ env | grep '^variable='
$                                 # No environment variable called variable
$ variable=Hello                  # Create local (non-exported) variable with value
$ env | grep '^variable='
$                                 # Still no environment variable called variable
$ export variable                 # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye   # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$

For more information, see the entry for the export builtin in the GNU Bash manual, and also the sections on command execution environment and environment.

Note that non-exported variables will be available to subshells run via ( ... ) and similar notations because those subshells are direct clones of the main shell:

$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$

The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.

Some information about subshells can be found under command grouping and command execution environment in the Bash manual.

I managed to stop the video using "get(0)" (Retrieve the DOM elements matched by the jQuery object):

$("#closeSimple").click(function() {
    $("div#simpleModal").removeClass("show");
    $("#videoContainer").get(0).pause();
    return false;
});

The client machine needs a proper font that has a glyph for this character to display it. But Times New Roman doesn’t. Try Arial Unicode MS or Lucida Grande instead:

<span style="font-family: Arial Unicode MS, Lucida Grande">
    &#10003; &#10004;
</span>

This works for me on Windows XP in IE 5.5, IE 6.0, FF 3.0.6.

A basic implementation which you'll need to adapt would look something like this:

function insertParam(key, value) {
    key = encodeURIComponent(key);
    value = encodeURIComponent(value);

    // kvp looks like ['key1=value1', 'key2=value2', ...]
    var kvp = document.location.search.substr(1).split('&');
    let i=0;

    for(; i<kvp.length; i++){
        if (kvp[i].startsWith(key + '=')) {
            let pair = kvp[i].split('=');
            pair[1] = value;
            kvp[i] = pair.join('=');
            break;
        }
    }

    if(i >= kvp.length){
        kvp[kvp.length] = [key,value].join('=');
    }

    // can return this or...
    let params = kvp.join('&');

    // reload page with new params
    document.location.search = params;
}

This is approximately twice as fast as a regex or search based solution, but that depends completely on the length of the querystring and the index of any match

the slow regex method I benchmarked against for completions sake (approx +150% slower)

function insertParam2(key,value)
{
    key = encodeURIComponent(key); value = encodeURIComponent(value);

    var s = document.location.search;
    var kvp = key+"="+value;

    var r = new RegExp("(&|\\?)"+key+"=[^\&]*");

    s = s.replace(r,"$1"+kvp);

    if(!RegExp.$1) {s += (s.length>0 ? '&' : '?') + kvp;};

    //again, do what you will here
    document.location.search = s;
}

Try experimenting with something like this also:

HTML

 <ul class="inlineList">
   <li>She</li>
   <li>Needs</li>
   <li>More Padding, Captain!</li>
 </ul>

CSS

 .inlineList {
   display: flex;
   flex-direction: row;
   /* Below sets up your display method: flex-start|flex-end|space-between|space-around */
   justify-content: flex-start; 
   /* Below removes bullets and cleans white-space */
   list-style: none;
   padding: 0;
   /* Bonus: forces no word-wrap */
   white-space: nowrap;
 }
 /* Here, I got you started.
 li {
   padding-top: 50px;
   padding-bottom: 50px;
   padding-left: 50px;
   padding-right: 50px;
 }
 */

I made a codepen to illustrate: http://codepen.io/agm1984/pen/mOxaEM

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on.

See Common Sequence Operations:

Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length.

Also Value Comparisons for further details:

Lexicographical comparison between built-in collections works as follows:

• For two collections to compare equal, they must be of the same type, have the same length, and each pair of corresponding elements must compare equal (for example, [1,2] == (1,2) is false because the type is not the same).
• Collections that support order comparison are ordered the same as their first unequal elements (for example, [1,2,x] <= [1,2,y] has the same value as x <= y). If a corresponding element does not exist, the shorter collection is ordered first (for example, [1,2] < [1,2,3] is true).

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is considered smaller (for example, [1,2] < [1,2,3] returns True).

Note 1: < and > do not mean "smaller than" and "greater than" but "is before" and "is after": so (0, 1) "is before" (1, 0).

Note 2: tuples must not be considered as vectors in a n-dimensional space, compared according to their length.

Note 3: referring to question https://stackoverflow.com/questions/36911617/python-2-tuple-comparison: do not think that a tuple is "greater" than another only if any element of the first is greater than the corresponding one in the second.

Not exactly an answer but perhaps a follow-up question (original question was not explicit):

readlink is fine if you actually want to follow symlinks. But there is also a use case for merely normalizing ./ and ../ and // sequences, which can be done purely syntactically, without canonicalizing symlinks. readlink is no good for this, and neither is realpath.

for f in $paths; do (cd $f; pwd); done

works for existing paths, but breaks for others.

A sed script would seem to be a good bet, except that you cannot iteratively replace sequences (/foo/bar/baz/../.. -> /foo/bar/.. -> /foo) without using something like Perl, which is not safe to assume on all systems, or using some ugly loop to compare the output of sed to its input.

FWIW, a one-liner using Java (JDK 6+):

jrunscript -e 'for (var i = 0; i < arguments.length; i++) {println(new java.io.File(new java.io.File(arguments[i]).toURI().normalize()))}' $paths

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

As stated on Installing MySQL-python on mac :

pip uninstall MySQL-python
brew install mysql
pip install MySQL-python

Then test it :

python -c "import MySQLdb"

You can use cookies for save postback data from one page to another page.After spending a lot time finally i was able to make this happen. I am suggesting my answer to you(this is fully working since I also needed this).

first give your li tag to valid id name like

<ul class="nav nav-list">_x000D_
    <li id="tab1" class="active"><a href="/">Link 1</a></li>_x000D_
    <li id="tab2"><a href="/link2">Link 2</a></li>_x000D_
    <li id="tab3"><a href="/link3">Link 3</a></li>_x000D_
</ul>

After that copy and paste this script. since I have written some javascript for reading, deleting and creating cookies.

 $('.nav li a').click(function (e) {_x000D_

Note: Make sure you have implmeted according to your requirement. I have written this script according to my implementation and its working fine for me.

You have to use the numeric sort option:

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

There are several issues here.

1. You can't assign DataContext as DataContext="{Binding Employee}" because it's a complex object which can't be assigned as string. So you have to use <Window.DataContext></Window.DataContext> syntax.
2. You assign the class that represents the data context object to the view, not an individual property so {Binding Employee} is invalid here, you just have to specify an object.
3. Now when you assign data context using valid syntax like below

   <Window.DataContext>
      <local:Employee/>
   </Window.DataContext>

know that you are creating a new instance of the Employee class and assigning it as the data context object. You may well have nothing in default constructor so nothing will show up. But then how do you manage it in code behind file? You have typecast the DataContext.

    private void my_button_Click(object sender, RoutedEventArgs e)
    {
        Employee e = (Employee) DataContext;
    }

4. A second way is to assign the data context in the code behind file itself. The advantage then is your code behind file already knows it and can work with it.

   public partial class MainWindow : Window
   {
      Employee employee = new Employee();
   
      public MainWindow()
      {
          InitializeComponent();
   
          DataContext = employee;
      }
   }
   

as you can see in this question you should:

<item name="android:textColorPrimary">yourColor</item>

Above code changes the text color of the menu action items for API >= v21.

<item name="actionMenuTextColor">@android:color/holo_green_light</item>

Above is the code for API < v21

The language spec mentions comparison operators' behaviors:

comparison operators

In any comparison, the first operand must be assignable to the type of the second operand, or vice versa.

Assignability

A value x is assignable to a variable of type T ("x is assignable to T") in any of these cases:

• x's type is identical to T.
• x's type V and T have identical underlying types and at least one of V or T is not a named type.
• T is an interface type and x implements T.
• x is a bidirectional channel value, T is a channel type, x's type V and T have identical element types, and at least one of V or T is not a named type.
• x is the predeclared identifier nil and T is a pointer, function, slice, map, channel, or interface type.
• x is an untyped constant representable by a value of type T.

If you would like to stop jenkins and all its services on the server using Linux console (e.g. Ubuntu), run:

service jenkins start/stop/restart

This is useful when you need to make an image/volume snapshot and you want all services to stop writing to the disk/volume.

I think you should $_POST[][], i tried it and it work :)), tks

Using an additional state variable, such as an index variable (which you would normally use in languages such as C or PHP), is considered non-pythonic.

The better option is to use the built-in function enumerate(), available in both Python 2 and 3:

for idx, val in enumerate(ints):
    print(idx, val)

Check out PEP 279 for more.

Here is the rub:

    ::selection {
      background: #ffb7b7; /* WebKit/Blink Browsers /
    }
    ::-moz-selection {
      background: #ffb7b7; / Gecko Browsers */
    }

All I did was use different selection color for paragraphs with different classes:

    p.red::selection {
      background: #ffb7b7;
    }
    p.red::-moz-selection {
      background: #ffb7b7;
    }
    p.blue::selection {
      background: #a8d1ff;
    }
    p.blue::-moz-selection {
      background: #a8d1ff;
    }
    p.yellow::selection {
      background: #fff2a8;
    }
    p.yellow::-moz-selection {
      background: #fff2a8;
    }

<pre>/* Combining like this WILL NOT WORK */
p.yellow::selection,
p.yellow::-moz-selection {
  background: #fff2a8;
}</pre>

That's because browsers ignore the entire selector if there is a part of it they don't understand or is invalid. There is some exceptions to this (IE 7?) but not in relation to these selectors.

DEMO

LINK WHERE INFO IS FROM

Its simple, use

  Form.ShowDialog();

Instead

  Form.Show();

While using Form.ShowDialog()you cannot interact with the parent form until it closes.

I would recommend the following solution:

b = []
b[:] = a

This will copy all the elements from a to b. The copy will be value copy, not reference copy.

Another way to suppress the error: Add this line at the top in C/C++ file:

#define _CRT_SECURE_NO_WARNINGS

Doing a symlink solves the issue:

ln -s /usr/bin/nodejs /usr/bin/node

(My thanks and +1 vote to bodokaiser's answer).

Other posters gave some examples for situations in which you'd use daemon threads. My recommendation, however, is never to use them.

It's not because they're not useful, but because there are some bad side effects you can experience if you use them. Daemon threads can still execute after the Python runtime starts tearing down things in the main thread, causing some pretty bizarre exceptions.

More info here:

https://joeshaw.org/python-daemon-threads-considered-harmful/

https://mail.python.org/pipermail/python-list/2005-February/343697.html

Strictly speaking you never need them, it just makes implementation easier in some cases.

It's rare to see the difference nowadays because html 5 don't support framesets anymore. But back at the time we have frameset, document.location would redirect only the frame in which code is being executed, and window.location would redirect the entire page.

Try like Below

var Boolify = require('node-boolify').Boolify;
if (!Boolify(val)) {
    //your instruction
}

Refer node-boolify

If you remember which branch was checked out before (e.g. master) you could simply

git checkout master

to get out of detached HEAD state.

Generally speaking: git checkout <branchname> will get you out of that.

If you don't remember the last branch name, try

git checkout -

This also tries to check out your last checked out branch.

I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:

public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
    T key = default;
    foreach (KeyValuePair<T, W> pair in dict)
    {
        if (EqualityComparer<W>.Default.Equals(pair.Value, val))
        {
            key = pair.Key;
            break;
        }
    }
    return key;
}

Call it like follows:

public static void Main()
{
    Dictionary<string, string> dict = new Dictionary<string, string>()
    {
        {"1", "one"},
        {"2", "two"},
        {"3", "three"}
    };

    string key = KeyByValue(dict, "two");       
    Console.WriteLine("Key: " + key);
}

Works on .NET 2.0 and in other limited environments.

You can use nested.

There are tow function one is openTab() and another is closeMobileMenue(), Firstly we call openTab() and call another function inside closeMobileMenue().

function openTab() {
    window.open('https://play.google.com/store/apps/details?id=com.drishya');
    closeMobileMenue()   //After open new tab, Nav Menue will close.  
}

onClick={openTab}

From Ruby API:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

When you use require to load a file, you are usually accessing functionality that has been properly installed, and made accessible, in your system. require does not offer a good solution for loading files within the project’s code. This may be useful during a development phase, for accessing test data, or even for accessing files that are "locked" away inside a project, not intended for outside use.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1" 

Since neither "test" nor "test/data" are likely to be in Ruby’s library path (and for good reason), a normal require won’t find them. require_relative is a good solution for this particular problem.

You may include or omit the extension (.rb or .so) of the file you are loading.

path must respond to to_str.

You can find the documentation at http://extensions.rubyforge.org/rdoc/classes/Kernel.html

EditText txt = (EditText)findviewbyid(R.id.txt);

Editable str = txt.getText().toString();

Toast toast = Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG);  

toast.show();

For me the above solutions were close but added some unwanted /n's and dtype:object, so here's a modified version:

df.groupby(['name', 'month'])['text'].apply(lambda text: ''.join(text.to_string(index=False))).str.replace('(\\n)', '').reset_index()

If it is not defined in the web service or application or server (apache or IIS) that is hosting the web service consumable then you could create infinite connections until failure

import random
import urllib.request

def download_image(url):
    name = random.randrange(1,100)
    fullname = str(name)+".jpg"
    urllib.request.urlretrieve(url,fullname)     
download_image("http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg")

You can use the "Test Connection" feature after creating the ODBC connection through Control Panel > Administrative Tools > Data Sources.

To test a SQL command itself you could try:

http://www.sqledit.com/odbc/runner.html

http://www.sqledit.com/sqlrun.zip

Or (perhaps easier and more useful in the long run) you can make a test ASP.NET or PHP page in a couple minutes to run SQL statement yourself through IIS.

Some performance measurements, using timeit instead of trying to do it manually with time.

First, Apple 2.7.2 64-bit:

In [37]: %timeit collections.deque((x for x in xrange(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.05 s per loop

Now, python.org 3.3.0 64-bit:

In [83]: %timeit collections.deque((x for x in range(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.32 s per loop

In [84]: %timeit collections.deque((x for x in xrange(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.31 s per loop

In [85]: %timeit collections.deque((x for x in iter(range(10000000)) if x%4 == 0), maxlen=0) 
1 loops, best of 3: 1.33 s per loop

Apparently, 3.x range really is a bit slower than 2.x xrange. And the OP's xrange function has nothing to do with it. (Not surprising, as a one-time call to the __iter__ slot isn't likely to be visible among 10000000 calls to whatever happens in the loop, but someone brought it up as a possibility.)

But it's only 30% slower. How did the OP get 2x as slow? Well, if I repeat the same tests with 32-bit Python, I get 1.58 vs. 3.12. So my guess is that this is yet another of those cases where 3.x has been optimized for 64-bit performance in ways that hurt 32-bit.

But does it really matter? Check this out, with 3.3.0 64-bit again:

In [86]: %timeit [x for x in range(10000000) if x%4 == 0]
1 loops, best of 3: 3.65 s per loop

So, building the list takes more than twice as long than the entire iteration.

And as for "consumes much more resources than Python 2.6+", from my tests, it looks like a 3.x range is exactly the same size as a 2.x xrange—and, even if it were 10x as big, building the unnecessary list is still about 10000000x more of a problem than anything the range iteration could possibly do.

And what about an explicit for loop instead of the C loop inside deque?

In [87]: def consume(x):
   ....:     for i in x:
   ....:         pass
In [88]: %timeit consume(x for x in range(10000000) if x%4 == 0)
1 loops, best of 3: 1.85 s per loop

So, almost as much time wasted in the for statement as in the actual work of iterating the range.

If you're worried about optimizing the iteration of a range object, you're probably looking in the wrong place.

Meanwhile, you keep asking why xrange was removed, no matter how many times people tell you the same thing, but I'll repeat it again: It was not removed: it was renamed to range, and the 2.x range is what was removed.

Here's some proof that the 3.3 range object is a direct descendant of the 2.x xrange object (and not of the 2.x range function): the source to 3.3 range and 2.7 xrange. You can even see the change history (linked to, I believe, the change that replaced the last instance of the string "xrange" anywhere in the file).

So, why is it slower?

Well, for one, they've added a lot of new features. For another, they've done all kinds of changes all over the place (especially inside iteration) that have minor side effects. And there'd been a lot of work to dramatically optimize various important cases, even if it sometimes slightly pessimizes less important cases. Add this all up, and I'm not surprised that iterating a range as fast as possible is now a bit slower. It's one of those less-important cases that nobody would ever care enough to focus on. No one is likely to ever have a real-life use case where this performance difference is the hotspot in their code.

Python equivalent code for a QMessageBox which consist of a question in it and Yes and No button. When Yes Button is clicked it will pop up another message box saying yes is clicked and same for No button also. You can push your own code after if block.

button_reply = QMessageBox.question(self,"Test", "Are you sure want to quit??", QMessageBox.Yes,QMessageBox.No,)

if button_reply == QMessageBox.Yes:
    QMessageBox.information(self, "Test", "Yes Button Was Clicked")
else :
    QMessageBox.information(self, "Test", "No Button Was Clicked")

Another alternative

Just check the class in the Abstract class and Assert or Exception, whatever you fancy.

@implementation Orange
- (instancetype)init
{
    self = [super init];
    NSAssert([self class] != [Orange class], @"This is an abstract class");
    if (self) {
    }
    return self;
}
@end

This removes the necessity to override init

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

To add and enhance the other answers, in the console, enter $($0) to get the element. If it's an Angularjs application, a jQuery lite version is loaded by default.

If you are not using jQuery, you can use angular.element($0) as in:

angular.element($0).scope()

To check if you have jQuery and the version, run this command in the console:

$.fn.jquery

If you have inspected an element, the currently selected element is available via the command line API reference $0. Both Firebug and Chrome have this reference.

However, the Chrome developer tools will make available the last five elements (or heap objects) selected through the properties named $0, $1, $2, $3, $4 using these references. The most recently selected element or object can be referenced as $0, the second most recent as $1 and so on.

Here is the Command Line API reference for Firebug that lists it's references.

$($0).scope() will return the scope associated with the element. You can see its properties right away.

Some other things that you can use are:

• View an elements parent scope:

$($0).scope().$parent.

• You can chain this too:

$($0).scope().$parent.$parent

• You can look at the root scope:

$($0).scope().$root

• If you highlighted a directive with isolate scope, you can look at it with:

$($0).isolateScope()

I not expert in MySQL but you probably should look on triggers e.g. BEFORE INSERT. In the trigger you can run select query on your original table and if it found something just update the row 'logins' instead of inserting new values. But all this depends on version of MySQL you running.

Following Makefile code worked:

obj-m = hello.o

A little bit hardcore but

this.router.onSameUrlNavigation = 'reload';
this.router.navigateByUrl(this.router.url).then(() => {

    this.router.onSameUrlNavigation = 'ignore';

});

If you have a small number of values to auto complete, you can simply add them in xaml. Typing will invoke auto-complete, plus you have dropdowns too.

<ComboBox Text="{Binding CheckSeconds, UpdateSourceTrigger=PropertyChanged}"
          IsEditable="True">
    <ComboBoxItem Content="60"/>
    <ComboBoxItem Content="120"/>
    <ComboBoxItem Content="180"/>
    <ComboBoxItem Content="300"/>
    <ComboBoxItem Content="900"/>
</ComboBox>

Minor note: Please consider that when you import from a default export, the naming is completely independent. This actually has an impact on refactorings.

Let's say you have a class Foo like this with a corresponding import:

export default class Foo { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export
import Foo from './Foo'

Now if you refactor your Foo class to be Bar and also rename the file, most IDEs will NOT touch your import. So you will end up with this:

export default class Bar { }

// The name 'Foo' could be anything, since it's just an
// Identifier for the default export.
import Foo from './Bar'

Especially in TypeScript, I really appreciate named exports and the more reliable refactoring. The difference is just the lack of the default keyword and the curly braces. This btw also prevents you from making a typo in your import since you have type checking now.

export class Foo { }

//'Foo' needs to be the class name. The import will be refactored
//in case of a rename!
import { Foo } from './Foo'

here is an example

 <a class="facultySelecter" data-faculty="ahs" href="#">Arts and Human Sciences</a></li>

    $('.facultySelecter').click(function() {        
    var unhide = $(this).data("faculty");
    });

this would set var unhide as ahs, so use .data("foo") to get the "foo" value of the data-* attribute you're looking to get

for (int i=0;i < Table.Rows.Count;i++)
{
      Var YourValue = Table.Rows[i]["ColumnName"];
}

If you are working a lot with graphs and ggplot, you might be tired to add the theme() each time. If you don't want to change the default theme as suggested earlier, you may find easier to create your own personal theme.

personal_theme = theme(plot.title = 
element_text(hjust = 0.5))

Say you have multiple graphs, p1, p2 and p3, just add personal_theme to them.

p1 + personal_theme
p2 + personal_theme
p3 + personal_theme

dat <- data.frame(
  time = factor(c("Lunch","Dinner"), 
levels=c("Lunch","Dinner")),
  total_bill = c(14.89, 17.23)
)
p1 = ggplot(data=dat, aes(x=time, y=total_bill, 
fill=time)) + 
  geom_bar(colour="black", fill="#DD8888", 
width=.8, stat="identity") + 
  guides(fill=FALSE) +
  xlab("Time of day") + ylab("Total bill") +
  ggtitle("Average bill for 2 people")

p1 + personal_theme

public V[] getV(DataTable dtCloned)

    V[] objV = new V[dtCloned.Rows.Count];
    MyClasses mc = new MyClasses();

    foreach (DataRow dr in dtCloned.Rows)
    {
        try
        {
            V vs = new V();
            vs.R = int.Parse(mc.ReplaceChar(dr["r"].ToString()).Trim());
            vs.S = Int64.Parse(mc.ReplaceChar(dr["s"].ToString()).Trim());
            objV[i] = vs;
            i++;
        }
        catch (Exception ex)
        {
            //
            DataRow row = dtError.NewRow();
            row["r"] = dr["r"].ToString();
            row["s"] = dr["s"].ToString();
            dtError.Rows.Add(row);
            intError++;
        }

Get the name of the class that exception object belongs:

e.__class__.__name__

and using print_exc() function will also print stack trace which is essential info for any error message.

Like this:

from traceback import print_exc

class CustomException(Exception): pass

try:
    raise CustomException("hi")
except Exception, e:
    print 'type is:', e.__class__.__name__
    print_exc()
    # print "exception happened!"

You will get output like this:

type is: CustomException
Traceback (most recent call last):
  File "exc.py", line 7, in <module>
    raise CustomException("hi")
CustomException: hi

And after print and analysis, the code can decide not to handle exception and just execute raise:

from traceback import print_exc

class CustomException(Exception): pass

def calculate():
    raise CustomException("hi")

try:
    calculate()
except Exception, e:
    if e.__class__ == CustomException:
        print 'special case of', e.__class__.__name__, 'not interfering'
        raise
    print "handling exception"

Output:

special case of CustomException not interfering

And interpreter prints exception:

Traceback (most recent call last):
  File "test.py", line 9, in <module>
    calculate()
  File "test.py", line 6, in calculate
    raise CustomException("hi")
__main__.CustomException: hi

After raise original exception continues to propagate further up the call stack. (Beware of possible pitfall) If you raise new exception it caries new (shorter) stack trace.

from traceback import print_exc

class CustomException(Exception): pass

def calculate():
    raise CustomException("hi")

try:
    calculate()
except Exception, e:
    if e.__class__ == CustomException:
        print 'special case of', e.__class__.__name__, 'not interfering'
        #raise CustomException(e.message)
        raise e
    print "handling exception"

Output:

special case of CustomException not interfering
Traceback (most recent call last):
  File "test.py", line 13, in <module>
    raise CustomException(e.message)
__main__.CustomException: hi    

Notice how traceback does not include calculate() function from line 9 which is the origin of original exception e.

I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.

eval $(curl -s "http://www.google.com/ig/api?stock=$stock"|sed 's/</\n</g' |sed '/data=/!d; s/ data=/=/g; s/\/>/; /g; s/</GF_/g' |tee /tmp/stockprice.tmp.log)

echo "$stock,$(date +%Y-%m-%d),$GF_open,$GF_high,$GF_low,$GF_last,$GF_volume"

Then you will have variables like $GF_last $GF_open $GF_volume etc. readily available. Run env or see inside /tmp/stockprice.tmp.log

http://www.google.com/ig/api?stock=TVIX&output=csv by itself returns:

Once I experienced the same error when I used junit and Mockito, I forgot to add @PrepareForTest for a static class.

Add below code fixed my problem.

@PrepareForTest({XXXXX.class})

_{Not sure it was the same case.}

Only semantics.

An HTTP PUT is supposed to accept the body of the request, and then store that at the resource identified by the URI.

An HTTP POST is more general. It is supposed to initiate an action on the server. That action could be to store the request body at the resource identified by the URI, or it could be a different URI, or it could be a different action.

PUT is like a file upload. A put to a URI affects exactly that URI. A POST to a URI could have any effect at all.

If you want to disable unreferenced local variable write in some header

template<class T>
void ignore (const T & ) {}

and use

catch(const Except & excpt) {
    ignore(excpt); // No warning
    // ...  
} 

After looking at this and trying it out I found it actually didn't allow more than one instance of jquery to run at a time. After searching around I found that this did just the trick and was a whole lot less code.

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
    <script>var $j = jQuery.noConflict(true);</script>
    <script>
      $(document).ready(function(){
       console.log($().jquery); // This prints v1.4.2
       console.log($j().jquery); // This prints v1.9.1
      });
   </script>

So then adding the "j" after the "$" was all I needed to do.

$j(function () {
        $j('.button-pro').on('click', function () {
            var el = $('#cnt' + this.id.replace('btn', ''));
            $j('#contentnew > div').not(el).animate({
                height: "toggle",
                opacity: "toggle"
            }, 100).hide();
            el.toggle();
        });
    });

Try this,

string Date = datePicker1.SelectedDate.Value.ToString("dd-MMM-yyyy");

It worked for me the output format will be '02-May-2016'

Here's why: As it is says in the Javadoc:

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.

This check is done in the next() method of the iterator (as you can see by the stacktrace). But we will reach the next() method only if hasNext() delivered true, which is what is called by the for each to check if the boundary is met. In your remove method, when hasNext() checks if it needs to return another element, it will see that it returned two elements, and now after one element was removed the list only contains two elements. So all is peachy and we are done with iterating. The check for concurrent modifications does not occur, as this is done in the next() method which is never called.

Next we get to the second loop. After we remove the second number the hasNext method will check again if can return more values. It has returned two values already, but the list now only contains one. But the code here is:

public boolean hasNext() {
        return cursor != size();
}

1 != 2, so we continue to the next() method, which now realizes that someone has been messing with the list and fires the exception.

Hope that clears your question up.

Summary

List.remove() will not throw ConcurrentModificationException when it removes the second last element from the list.

$date = '2014-02-25';
date('D', strtotime($date));

If you started docker using sudo , then you should run docker-compose up with sudo Like: sudo docker-compose up

also you can use this :

    if (! $('#leftmenu').children().length > 0 ) {
         // do something : e.x : remove a specific div
    }

I think it'll work for you !

http://site.mockito.org/mockito/docs/1.10.19/org/mockito/Matchers.html

anyObject() should fit your needs.

Also, you can always consider implementing hashCode() and equals() for the Bazoo class. This would make your code example work the way you want.

I had the same problem, and my solving was to replace :

return redirect(url_for('index'))

with

return render_template('indexo.html',data=Todos.query.all())

in my POST and DELETE route.

You can store this in a long. A long can store a value from -9223372036854775808 to 9223372036854775807.

I use PLAY JSON library you can find the mavn repo for only the JSON library not the whole framework here

    val json = "com.typesafe.play" %% "play-json" % version
    val typesafe = "typesafe.com" at "http://repo.typesafe.com/typesafe/releases/"

A very good tutorials about how to use them, are available here:

I got another Solution. Subtract parent property value from child property value

$('child-div').offset().top - $('parent-div').offset().top;

Try this

function findSelection(field) {
    var test = document.getElementsByName(field);
    var sizes = test.length;
    alert(sizes);
    for (i=0; i < sizes; i++) {
            if (test[i].checked==true) {
            alert(test[i].value + ' you got a value');     
            return test[i].value;
        }
    }
}


function submitForm() {

    var genderS =  findSelection("genderS");
    alert(genderS);
    return false;
}

A fiddle here.

see Doug Crockford's page on this. You have to do it indirectly with something that can access the scope of the private variable.

another example:

Incrementer = function(init) {
  var counter = init || 0;  // "counter" is a private variable
  this._increment = function() { return counter++; }
  this._set = function(x) { counter = x; }
}
Incrementer.prototype.increment = function() { return this._increment(); }
Incrementer.prototype.set = function(x) { return this._set(x); }

use case:

js>i = new Incrementer(100);
[object Object]
js>i.increment()
100
js>i.increment()
101
js>i.increment()
102
js>i.increment()
103
js>i.set(-44)
js>i.increment()
-44
js>i.increment()
-43
js>i.increment()
-42

First of all, set more safe initial data:

getInitialState : function() {
    return {data: {comments:[]}};
},

And ensure your ajax data.

It should work if you follow above two instructions like Demo.

Updated: you can just wrap the .map block with conditional statement.

if (this.props.data) {
  var commentNodes = this.props.data.map(function (comment){
      return (
        <div>
          <h1>{comment.author}</h1>
        </div>
      );
  });
}

IMHO, There is no need to install all the additional applications/packages.

Check available versions using the command:

> /usr/libexec/java_home -V
Matching Java Virtual Machines (8):
    11, x86_64: "Java SE 11-ea" /Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home
    10.0.2, x86_64: "Java SE 10.0.2"    /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home
    9.0.1, x86_64:  "Java SE 9.0.1" /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home
    1.8.0_181-zulu-8.31.0.1, x86_64:    "Zulu 8"    /Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home
    1.8.0_151, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home
    1.7.0_80, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
    1.6.0_65-b14-468, x86_64:   "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
    1.6.0_65-b14-468, i386: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Now if you want to pick Azul JDK 8 in the above list, and NOT Oracle's Java SE 8, invoke the command as below:

> /usr/libexec/java_home -v 1.8.0_181
/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home

To pick Oracle's Java SE 8 you would invoke the command:

> /usr/libexec/java_home -v 1.8.0_151
/Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home

As you can see the version number provided shall be the unique set of strings: 1.8.0_181 vs 1.8.0_151

You need to give the range a -1 step

 for i in range(10,0,-1):
    print i

And based on merkuro's solution, if you would like maximize the one on the left, you should use:

Has not been tested on IE, so it may look broken on IE.

It used to be a required part of a package (old, pre-3.3 "regular package", not newer 3.3+ "namespace package").

Here's the documentation.

Python defines two types of packages, regular packages and namespace packages. Regular packages are traditional packages as they existed in Python 3.2 and earlier. A regular package is typically implemented as a directory containing an __init__.py file. When a regular package is imported, this __init__.py file is implicitly executed, and the objects it defines are bound to names in the package’s namespace. The __init__.py file can contain the same Python code that any other module can contain, and Python will add some additional attributes to the module when it is imported.

But just click the link, it contains an example, more information, and an explanation of namespace packages, the kind of packages without __init__.py.

1. Go to the log view (to be able to go here go to View -> log view).
2. Double click on the line with the branch label stating that branch. Automatically, it will switch branch. (A prompt will dropdown and say switching branch.)
3. If you have two or more branches on the same line, it will ask you via prompt which branch you want to switch. Choose the specific branch from the dropdown and click ok.

To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.

OK, here is a step-by-step guide if you want to use COM.

1. You have to have Excel installed.
2. Add a reference to your project to the excel interop dll. To do this on the .NET tab select Microsoft.Office.Interop.Excel. There could be multiple assemblies with this name. Select the appropriate for your Visual Studio AND Excel version.
3. Here is a code sample to create a new Workbook and fill a column with the items from your list.

using NsExcel = Microsoft.Office.Interop.Excel;

public void ListToExcel(List<string> list)
{
    //start excel
    NsExcel.ApplicationClass excapp = new Microsoft.Office.Interop.Excel.ApplicationClass();

    //if you want to make excel visible           
    excapp.Visible = true;

    //create a blank workbook
    var workbook = excapp.Workbooks.Add(NsExcel.XlWBATemplate.xlWBATWorksheet);

    //or open one - this is no pleasant, but yue're probably interested in the first parameter
    string workbookPath = "C:\test.xls";
    var workbook = excapp.Workbooks.Open(workbookPath,
        0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
        true, false, 0, true, false, false);

    //Not done yet. You have to work on a specific sheet - note the cast
    //You may not have any sheets at all. Then you have to add one with NsExcel.Worksheet.Add()
    var sheet = (NsExcel.Worksheet)workbook.Sheets[1]; //indexing starts from 1

    //do something usefull: you select now an individual cell
    var range = sheet.get_Range("A1", "A1");
    range.Value2 = "test"; //Value2 is not a typo

    //now the list
    string cellName;
    int counter = 1;
    foreach (var item in list)
    {
        cellName = "A" + counter.ToString();
        var range = sheet.get_Range(cellName, cellName);
        range.Value2 = item.ToString();
        ++counter;
    }

    //you've probably got the point by now, so a detailed explanation about workbook.SaveAs and workbook.Close is not necessary
    //important: if you did not make excel visible terminating your application will terminate excel as well - I tested it
    //but if you did it - to be honest - I don't know how to close the main excel window - maybee somewhere around excapp.Windows or excapp.ActiveWindow
}

Unless I am misunderstanding what you are asking you can do this on the properties for your data grid view. You need to set the Anchor property to the sides you want it locked to.

You have added vendor/plugins/open_flash_chart_2 as “gitlink” entry, but never defined it as a submodule. Effectively you are using the internal feature that git submodule uses (gitlink entries) but you are not using the submodule feature itself.

You probably did something like this:

git clone git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2
git add vendor/plugins/open_flash_chart_2

This last command is the problem. The directory vendor/plugins/open_flash_chart_2 starts out as an independent Git repository. Usually such sub-repositories are ignored, but if you tell git add to explicitly add it, then it will create an gitlink entry that points to the sub-repository’s HEAD commit instead of adding the contents of the directory. It might be nice if git add would refuse to create such “semi-submodules”.

Normal directories are represented as tree objects in Git; tree objects give names, and permissions to the objects they contain (usually other tree and blob objects—directories and files, respectively). Submodules are represented as “gitlink” entries; gitlink entries only contain the object name (hash) of the HEAD commit of the submodule. The “source repository” for a gitlink’s commit is specified in the .gitmodules file (and the .git/config file once the submodule has been initialized).

What you have is an entry that points to a particular commit, without recording the source repository for that commit. You can fix this by either making your gitlink into a proper submodule, or by removing the gitlink and replacing it with “normal” content (plain files and directories).

Turn It into a Proper Submodule

The only bit you are missing to properly define vendor/plugins/open_flash_chart_2 as a submodule is a .gitmodules file. Normally (if you had not already added it as bare gitlink entry), you would just use git submodule add:

git submodule add git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

As you found, this will not work if the path already exists in the index. The solution is to temporarily remove the gitlink entry from the index and then add the submodule:

git rm --cached vendor/plugins/open_flash_chart_2
git submodule add git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

This will use your existing sub-repository (i.e. it will not re-clone the source repository) and stage a .gitmodules file that looks like this:

[submodule "vendor/plugins/open_flash_chart_2"]
    path = vendor/plugins/open_flash_chart_2
    url = git://github.com/korin/open_flash_chart_2_plugin.git vendor/plugins/open_flash_chart_2

It will also make a similar entry in your main repository’s .git/config (without the path setting).

Commit that and you will have a proper submodule. When you clone the repository (or push to GitHub and clone from there), you should be able to re-initialize the submodule via git submodule update --init.

Replace It with Plain Content

The next step assumes that your sub-repository in vendor/plugins/open_flash_chart_2 does not have any local history that you want to preserve (i.e. all you care about is the current working tree of the sub-repository, not the history).

If you have local history in the sub-repository that you care about, then you should backup the sub-repository’s .git directory before deleting it in the second command below. (Also consider the git subtree example below that preserves the history of the sub-repository’s HEAD).

git rm --cached vendor/plugins/open_flash_chart_2
rm -rf vendor/plugins/open_flash_chart_2/.git # BACK THIS UP FIRST unless you are sure you have no local changes in it
git add vendor/plugins/open_flash_chart_2

This time when adding the directory, it is not a sub-repository, so the files will be added normally. Unfortunately, since we deleted the .git directory there is no super-easy way to keep things up-to-date with the source repository.

You might consider using a subtree merge instead. Doing so will let you easily pull in changes from the source repository while keeping the files “flat” in your repository (no submodules). The third-party git subtree command is a nice wrapper around the subtree merge functionality.

git rm --cached vendor/plugins/open_flash_chart_2
git commit -m'converting to subtree; please stand by'
mv vendor/plugins/open_flash_chart_2 ../ofc2.local
git subtree add --prefix=vendor/plugins/open_flash_chart_2 ../ofc2.local HEAD
#rm -rf ../ofc2.local # if HEAD was the only tip with local history

Later:

git remote add ofc2 git://github.com/korin/open_flash_chart_2_plugin.git
git subtree pull --prefix=vendor/plugins/open_flash_chart_2 ofc2 master

git subtree push --prefix=vendor/plugins/open_flash_chart_2 [email protected]:me/my_ofc2_fork.git changes_for_pull_request

git subtree also has a --squash option that lets you avoid incorporating the source repository’s history into your history but still lets you pull in upstream changes.

1. Close all instances of Visual Studio.
2. Open Task Manager.
3. End all active IIS processes.
4. Restart Visual Studio.

Not specific to the question, but for folks who need the same kind of functionality expanded for clarity from previous answers:

# create some variables
str="someFileName.foo"
find=".foo"
replace=".bar"
# notice the the str isn't prefixed with $
#    this is just how this feature works :/
result=${str//$find/$replace}
echo $result    
# result is: someFileName.bar

str="someFileName.sally"
find=".foo"
replace=".bar"
result=${str//$find/$replace}
echo $result    
# result is: someFileName.sally because ".foo" was not found

Based on Jon Skeet answer i've made a class that permits to do it easily at work:

 * Better use it inside the enum so that only one of this object instance exist for each enum...
 * (a cache could solve this if needed)

 *
 * <p>
 * Basic usage exemple on an enum class called MyEnum:
 *
 *   private static final FailSafeValueOf<MyEnum> FAIL_SAFE = FailSafeValueOf.create(MyEnum.class);
 *   public static MyEnum failSafeValueOf(String enumName) {
 *       return FAIL_SAFE.valueOf(enumName);

 * You can also use it outside of the enum this way:

 * </p>

public class FailSafeValueOf<T extends Enum<T>> {

    private final Map<String,T> nameToEnumMap;

    private FailSafeValueOf(Class<T> enumClass) {
        Map<String,T> map = Maps.newHashMap();
        for ( T value : EnumSet.allOf(enumClass)) {
            map.put( value.name() , value);

Notice that i used Guava to make an ImmutableMap but actually you could use a normal map i think since the map is never returned...

The accepted answer works well except for the fact that the javascript is briefly displayed in whatever the ajax target element is. To get around this, create a partial view called _Redirect with the following code:

@model string
<script>
   window.location = '@Model';
</script>

Then, in the controller replace

return Redirect(Url.Action("Index", "Home"));

with

return PartialView("_Redirect",Url.Action("Index", "Home"));

The effect is the same as the accepted answer, but without the brief artifact in the display. Place the _Redirect.cshtml in the shared folder so it can be used from anywhere.

You can use netstat command

netstat --listen

To display open ports and established TCP connections,

netstat -vatn

To display only open UDP ports try the following command:

netstat -vaun

I had the same issue running Rider/VS, both were using IIS Express to run it. I was having the issue with Postman, Chrome, Firefox and front end application calling it.

Turns out that because my laptop was appropriated for me when i started working for this company the previous developer had clicked No when asked if he wanted to use the Developer Cert the first time he ran IIS Express.

This was fixed on Windows 10 by going to Add Remove Programs (from the new UI there is a link on the right to launch the classic application for Adding and Removing Programs) then Repair IIS 10.0 or 8 or whatever version you are running.

Then try running the application again (I did this in VS but assume that Rider would do the same) and when asked whether you would like to use the Developer Certificate you click YES.

Hours wasted on this, but all sorted after that!

According to this MSDN blog: https://blogs.msdn.microsoft.com/manishagarwal/2005/09/28/resolving-file-references-in-team-build-part-2/

There is a search order for assemblies when building. The search order is as follows:

• Files from the current project – indicated by ${CandidateAssemblyFiles}.
• $(ReferencePath) property that comes from .user/targets file.
• %(HintPath) metadata indicated by reference item.
• Target framework directory.
• Directories found in registry that uses AssemblyFoldersEx Registration.
• Registered assembly folders, indicated by ${AssemblyFolders}.
• $(OutputPath) or $(OutDir)
• GAC

So, if the desired assembly is found by HintPath, but an alternate assembly can be found using ReferencePath, it will prefer the ReferencePath'd assembly to the HintPath'd one.

The nextInt() method leaves the \n (end line) symbol and is picked up immediately by nextLine(), skipping over the next input. What you want to do is use nextLine() for everything, and parse it later:

String nextIntString = keyboard.nextLine(); //get the number as a single line
int nextInt = Integer.parseInt(nextIntString); //convert the string to an int

This is by far the easiest way to avoid problems--don't mix your "next" methods. Use only nextLine() and then parse ints or separate words afterwards.

Also, make sure you use only one Scanner if your are only using one terminal for input. That could be another reason for the exception.

Last note: compare a String with the .equals() function, not the == operator.

if (playAgain == "yes"); // Causes problems
if (playAgain.equals("yes")); // Works every time

The only thing the eclipse plugin is checking is the tomcat version inside:

catalina.jar!/org/apache/catalina/util/ServerInfo.properties

I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse

In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:

.settings/org.eclipse.wst.common.project.facet.core.xml

And change the web version to 2.5

<installed facet="jst.web" version="2.5"/>

Another approach to this would put a span element with a display:block style inside the p element each time you need the content to break. It would only be useful when your p content is static.

<p>this is a not-dynamic text and I want to put<span style="display:block">the following words in the next line</span>and these other words in a third one</p>

It would output:

This is a not-dynamic text and I want to put

the following words in the next line

and these others in a third one

This allows you to change your text line-breaks in different viewports without JS.

If you just want simple encryption (i.e., possible for a determined cracker to break, but locking out most casual users), just pick two passphrases of equal length, say:

deoxyribonucleicacid
while (x>0) { x-- };

and xor your data with both of them (looping the passphrases if necessary)^(a). For example:

1111-2222-3333-4444-5555-6666-7777
deoxyribonucleicaciddeoxyribonucle
while (x>0) { x-- };while (x>0) { 

Someone searching your binary may well think the DNA string is a key, but they're unlikely to think the C code is anything other than uninitialized memory saved with your binary.

^(a) Keep in mind this is very simple encryption and, by some definitions, may not be considered encryption at all (since the intent of encryption is to prevent unauthorised access rather than just make it more difficult). Although, of course, even the strongest encryption is insecure when someone's standing over the key-holders with a steel pipe.

As stated in the first sentence, this is a means to make it difficult enough for the casual attacker that they'll move on. It's similar to preventing burglaries on your home - you don't need to make it impregnable, you just need to make it less pregnable than the house next door :-)

export class Dashboard {
    innerHeight: any;
    innerWidth: any;
    constructor() {
        this.innerHeight = (window.screen.height) + "px";
        this.innerWidth = (window.screen.width) + "px";
    }
}

HTTP authorization does not differ between GET and POST requests, so I would first assume that something else is wrong. Instead of setting the Authorization header directly, I would suggest using the java.net.Authorization class, but I am not sure if it solves your problem. Perhaps your server is somehow configured to require a different authorization scheme than "basic" for post requests?

I'll broadly agree with Vagrant on the cause:

1. your action was executing, writing markup to response stream
2. the stream was unbuffered forcing the response headers to get written before the markup writing could begin.
3. Your view encountered a runtime error
4. Exception handler kicks in trying to set the status code to something else non-200
5. Fails because the headers have already been sent.

Where I disagree with Vagrant is the "cause no errors in binding" remedy - you could still encounter runtime errors in View binding e.g. null reference exceptions.

A better solution for this is to ensure that Response.BufferOutput = true; before any bytes are sent to the Response stream. e.g. in your controller action or On_Begin_Request in application. This enables server transfers, cookies/headers to be set etc. right the way up to naturally ending response, or calling end/flush.

Of course also check that buffer isn't being flushed/set to false further down in the stack too.

MSDN Reference: HttpResponse.BufferOutput

Watch out for the trap I got into: When checking if certain value is not present in an array, you shouldn't do:

SELECT value_variable != ANY('{1,2,3}'::int[])

but use

SELECT value_variable != ALL('{1,2,3}'::int[])

instead.

original answer moved to this topic .

JIT-Just in time the word itself says when it's needed (on demand)

Typical scenario:

The source code is completely converted into machine code

JIT scenario:

The source code will be converted into assembly language like structure [for ex IL (intermediate language) for C#, ByteCode for java].

The intermediate code is converted into machine language only when the application needs that is required codes are only converted to machine code.

JIT vs Non-JIT comparison:

• In JIT not all the code is converted into machine code first a part of the code that is necessary will be converted into machine code then if a method or functionality called is not in machine then that will be turned into machine code... it reduces burden on the CPU.

• As the machine code will be generated on run time....the JIT compiler will produce machine code that is optimised for running machine's CPU architecture.

JIT Examples:

1. In Java JIT is in JVM (Java Virtual Machine)
2. In C# it is in CLR (Common Language Runtime)
3. In Android it is in DVM (Dalvik Virtual Machine), or ART (Android RunTime) in newer versions.

public static String convertDate(String dateInMilliseconds,String dateFormat) {
    return DateFormat.format(dateFormat, Long.parseLong(dateInMilliseconds)).toString();
}

Call this function

convertDate("82233213123","dd/MM/yyyy hh:mm:ss");

possible just do:

static const std::string RECTANGLE() const {
    return "rectangle";
} 

or

#define RECTANGLE "rectangle"

This error happened to me when a previous build on my simulator / phone was being uploaded with different credentials. What I had to do was run:

adb uninstall com.exampleappname

Once I did that I was able to rerun the build and generate an APK.

Now use np.array_equal. From documentation:

np.array_equal([1, 2], [1, 2])
True
np.array_equal(np.array([1, 2]), np.array([1, 2]))
True
np.array_equal([1, 2], [1, 2, 3])
False
np.array_equal([1, 2], [1, 4])
False

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

TL;DR: The biggest difference in everyday use isn't nested dependencies... it's the difference between modules and globals.

I think the previous posters have covered well some of the basic distinctions. (npm's use of nested dependencies is indeed very helpful in managing large, complex applications, though I don't think it's the most important distinction.)

I'm surprised, however, that nobody has explicitly explained one of the most fundamental distinctions between Bower and npm. If you read the answers above, you'll see the word 'modules' used often in the context of npm. But it's mentioned casually, as if it might even just be a syntax difference.

But this distinction of modules vs. globals (or modules vs. 'scripts') is possibly the most important difference between Bower and npm. The npm approach of putting everything in modules requires you to change the way you write Javascript for the browser, almost certainly for the better.

The Bower Approach: Global Resources, Like <script> Tags

At root, Bower is about loading plain-old script files. Whatever those script files contain, Bower will load them. Which basically means that Bower is just like including all your scripts in plain-old <script>'s in the <head> of your HTML.

So, same basic approach you're used to, but you get some nice automation conveniences:

• You used to need to include JS dependencies in your project repo (while developing), or get them via CDN. Now, you can skip that extra download weight in the repo, and somebody can do a quick bower install and instantly have what they need, locally.
• If a Bower dependency then specifies its own dependencies in its bower.json, those'll be downloaded for you as well.

But beyond that, Bower doesn't change how we write javascript. Nothing about what goes inside the files loaded by Bower needs to change at all. In particular, this means that the resources provided in scripts loaded by Bower will (usually, but not always) still be defined as global variables, available from anywhere in the browser execution context.

The npm Approach: Common JS Modules, Explicit Dependency Injection

All code in Node land (and thus all code loaded via npm) is structured as modules (specifically, as an implementation of the CommonJS module format, or now, as an ES6 module). So, if you use NPM to handle browser-side dependencies (via Browserify or something else that does the same job), you'll structure your code the same way Node does.

Smarter people than I have tackled the question of 'Why modules?', but here's a capsule summary:

• Anything inside a module is effectively namespaced, meaning it's not a global variable any more, and you can't accidentally reference it without intending to.
• Anything inside a module must be intentionally injected into a particular context (usually another module) in order to make use of it
• This means you can have multiple versions of the same external dependency (lodash, let's say) in various parts of your application, and they won't collide/conflict. (This happens surprisingly often, because your own code wants to use one version of a dependency, but one of your external dependencies specifies another that conflicts. Or you've got two external dependencies that each want a different version.)
• Because all dependencies are manually injected into a particular module, it's very easy to reason about them. You know for a fact: "The only code I need to consider when working on this is what I have intentionally chosen to inject here".
• Because even the content of injected modules is encapsulated behind the variable you assign it to, and all code executes inside a limited scope, surprises and collisions become very improbable. It's much, much less likely that something from one of your dependencies will accidentally redefine a global variable without you realizing it, or that you will do so. (It can happen, but you usually have to go out of your way to do it, with something like window.variable. The one accident that still tends to occur is assigning this.variable, not realizing that this is actually window in the current context.)
• When you want to test an individual module, you're able to very easily know: exactly what else (dependencies) is affecting the code that runs inside the module? And, because you're explicitly injecting everything, you can easily mock those dependencies.

To me, the use of modules for front-end code boils down to: working in a much narrower context that's easier to reason about and test, and having greater certainty about what's going on.

It only takes about 30 seconds to learn how to use the CommonJS/Node module syntax. Inside a given JS file, which is going to be a module, you first declare any outside dependencies you want to use, like this:

var React = require('react');

Inside the file/module, you do whatever you normally would, and create some object or function that you'll want to expose to outside users, calling it perhaps myModule.

At the end of a file, you export whatever you want to share with the world, like this:

module.exports = myModule;

Then, to use a CommonJS-based workflow in the browser, you'll use tools like Browserify to grab all those individual module files, encapsulate their contents at runtime, and inject them into each other as needed.

AND, since ES6 modules (which you'll likely transpile to ES5 with Babel or similar) are gaining wide acceptance, and work both in the browser or in Node 4.0, we should mention a good overview of those as well.

More about patterns for working with modules in this deck.

EDIT (Feb 2017): Facebook's Yarn is a very important potential replacement/supplement for npm these days: fast, deterministic, offline package-management that builds on what npm gives you. It's worth a look for any JS project, particularly since it's so easy to swap it in/out.

EDIT (May 2019) "Bower has finally been deprecated. End of story." (h/t: @DanDascalescu, below, for pithy summary.)

And, while Yarn is still active, a lot of the momentum for it shifted back to npm once it adopted some of Yarn's key features.

That depends on the nature of the information you want to return.

If it is a single integer value, you can use the return statement

 create proc myproc
 as 
 begin
     return 1
 end
 go
 declare @i int
 exec @i = myproc

If you have a non integer value, or a number of scalar values, you can use output parameters

create proc myproc
  @a int output,
  @b varchar(50) output
as
begin
  select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output

If you want to return a dataset, you can use insert exec

create proc myproc
as 
begin
     select name from sysobjects
end
go

declare @t table (name varchar(100))
insert @t (name)
exec myproc

You can even return a cursor but that's just horrid so I shan't give an example :)

In my case (.NET Core 3.0) I had to configure JSON serialization to resolve camelCase properties using AddNewtonsoftJson():

services.AddMvc(options =>
{
    // (Irrelevant for the answer)
})
.AddNewtonsoftJson(options =>
{
    options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});

Do this in your Startup / Dependency Injection setup.

If bringing existing Visual Studio 2015 solution into Visual Studio 2017 and you want to build it with c++17 native compiler, you should first Retarget the solution/projects to v141 , THEN the dropdown will appear as described above ( Configuration Properties -> C/C++ -> Language -> Language Standard)

unit test: testing of individual module or independent component in an application is known to be unit testing , the unit testing will be done by developer.

integration test: combining all the modules and testing the application to verify the communication and the data flow between the modules are working properly or not , this testing also performed by developers.

funcional test checking the individual functionality of an application is mean to be functional testing

acceptance testing this testing is done by end user or customer whether the build application is according to the customer requirement , and customer specification this is known to be acceptance testing

If you have WordPress bootstrap loaded you can use get_home_path() function to get path to the WordPress root directory.

char string1[] = "test";
char string2[] = "string";
int len = sizeof(string1) + sizeof(string2);
char totalString[len];
sprintf(totalString, "%s%s",string1,string2);

One good solution is to run only desired services like this:

docker-compose up --build $(<services.txt)

and services.txt file look like this:

services1 services2, etc

of course if dependancy (depends_on), need to run related services together.

--build is optional, just for example.

You can also use IteratorUtils from Apache commons-collections, although it doesn't support generics:

List list = IteratorUtils.toList(iterator);

The maximum request size is, by default, 4MB (4096 KB)

This is explained here.

The above article also explains how to fix this issue :)

You can try this too:

Center(
  child: Stack(
    children: [],
  ),
)

I have created a Doctrine2 Logger that does exactly this. It "hydrates" the parametrized sql query with the values using Doctrine 2 own data type conversors.

You did not install the correct Eclipse distribution. Try install the one labeled "Eclipse IDE for Java EE Developers".

I installed the 8.1 SDK's version:

https://developer.microsoft.com/en-us/windows/downloads/sdk-archive

It used 1GB (a little more) in the installation.

Update October, 9. There's a https error: the sdksetup link is https://go.microsoft.com/fwlink/p/?LinkId=323507

"Save link as" should help.

As @ashishduh mentioned above, using android:autoLink="phone is also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.

Example:

08034448845 won't work

but +2348034448845 will

Since you are writing for Python 3.x, you'll want to begin your script with:

#!/usr/bin/env python3

If you use:

#!/usr/bin/env python

It will default to Python 2.x. These go on the first line of your script, if there is nothing that starts with #! (aka the shebang).

If your scripts just start with:

#! python

Then you can change it to:

#! python3

Although this shorter formatting is only recognized by a few programs, such as the launcher, so it is not the best choice.

The first two examples are much more widely used and will help ensure your code will work on any machine that has Python installed.

I break the task up into smaller units. Test with different batch size intervals for your table, until you find an interval that performs optimally. Here is a sample that I have used in the past.

declare @counter int 
declare @numOfRecords int
declare @batchsize int

set @numOfRecords = (SELECT COUNT(*) AS NumberOfRecords FROM <TABLE> with(nolock))
set @counter = 0 
set @batchsize = 2500

set rowcount @batchsize
while @counter < (@numOfRecords/@batchsize) +1
begin 
set @counter = @counter + 1 
Update table set int_field = -1 where int_field <> -1;
end 
set rowcount 0

Missing ; after var_dump($row)

There are better answers here, but how I fix this may be relevant for someone:

After checking out the project from SVN, instead of choosing the 1.7 version, I chose Subversion 1.6 and it worked.

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

Use the .classList.add() method:

const element = document.querySelector('div.foo');_x000D_
element.classList.add('bar');_x000D_
console.log(element.className);

<div class="foo"></div>

This method is better than overwriting the className property, because it doesn't remove other classes and doesn't add the class if the element already has it.

You can also toggle or remove classes using element.classList (see the MDN documentation).

user2540984, as well as many others have pointed out that you can try increasing your timeout settings. I myself faced a similar issue to this one and tried to change my timeout settings in the /etc/nginx/nginx.conf file, as almost everyone in these threads suggest. This, however, did not help me a single bit; there was no apparent change in NGINX' timeout settings. After many hours of searching, I finally managed to solve my issue.

The solution lies in this forum thread, and what it says is that you should put your timeout settings in /etc/nginx/conf.d/timeout.conf (and if this file doesn't exist, you should create it). I used the same settings as suggested in the thread:

proxy_connect_timeout 600;
proxy_send_timeout 600;
proxy_read_timeout 600;
send_timeout 600;

This might not be the solution to your particular problem, but if anyone else notices that the timeout changes in /etc/nginx/nginx.conf don't do anything, I hope this answer helps!

Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.

If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.

If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("#el").offset().top - $(document).scrollTop()

If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

To run your_command as a subprocess in a different directory, pass cwd parameter, as suggested in @wim's answer:

import subprocess

subprocess.check_call(['your_command', 'arg 1', 'arg 2'], cwd=working_dir)

A child process can't change its parent's working directory (normally). Running cd .. in a child shell process using subprocess won't change your parent Python script's working directory i.e., the code example in @glglgl's answer is wrong. cd is a shell builtin (not a separate executable), it can change the directory only in the same process.

The accepted answer is not necessarily correct. queuecomplete will be called even when the selected file is larger than the max file size.

The proper event to use is successmultiple or completemultiple.

Just like ASP.NET variant, except put the hidden input with the same name before the actual checkbox (of the same name). Only last values will be sent. This way if a box is checked then its name and value "on" is sent, whereas if it's unchecked then the name of the corresponding hidden input and whatever value you might like to give it will be sent. In the end you will get the $_POST array to read, with all checked and unchecked elements in it, "on" and "false" values, no duplicate keys. Easy to process in PHP.

I just installed SQL Developer 4.0.0.13 and the SetJavaHome can now be overridden by a user-specific configuration file (not sure if this is new to 4.0.0.13 or not).

The location of this user-specific configuration file can be seen in the user.conf property under 'Help -> About' on the 'Properties' tab. For example, mine was set to:

C:\Users\username\AppData\Roaming\sqldeveloper\1.0.0.0.0\product.conf

On Windows 7.

The first section of this file is used to set the JDK that SQLDeveloper should use:

#
# By default, the product launcher will search for a JDK to use, and if none
# can be found, it will ask for the location of a JDK and store its location
# in this file. If a particular JDK should be used instead, uncomment the
# line below and set the path to your preferred JDK.
#
SetJavaHome C:\Program Files (x86)\Java\jdk1.7.0_03

This setting overrides the setting in sqldeveloper.conf

/^$|\s+/ if this matched, there's whitespace or its empty.

You just need to add an "A" record in the DNS manager on Godaddy. In that "A" record put your IP from dreamhost.

I know this works since I'm doing the very same thing.

Scott's answer will work for classes of checkboxes. If you want individual checkboxes, you have to be a little sneakier. If you're just doing one box, it's better to do it with IDs. This example does it by specific check boxes and doesn't require jQuery. It's also a nice little example of how you can get those pesky control IDs into your Javascript.

The .ascx:

<script type="text/javascript">

    function checkAgreement(source, args)
    {                
        var elem = document.getElementById('<%= chkAgree.ClientID %>');
        if (elem.checked)
        {
            args.IsValid = true;
        }
        else
        {        
            args.IsValid = false;
        }
    }

    function checkAge(source, args)
    {
        var elem = document.getElementById('<%= chkAge.ClientID %>');
        if (elem.checked)
        {
            args.IsValid = true;
        }
        else
        {
            args.IsValid = false;
        }    
    }

</script>

<asp:CheckBox ID="chkAgree" runat="server" />
<asp:Label AssociatedControlID="chkAgree" runat="server">I agree to the</asp:Label>
<asp:HyperLink ID="lnkTerms" runat="server">Terms & Conditions</asp:HyperLink>
<asp:Label AssociatedControlID="chkAgree" runat="server">.</asp:Label>
<br />

<asp:CustomValidator ID="chkAgreeValidator" runat="server" Display="Dynamic"
    ClientValidationFunction="checkAgreement">
    You must agree to the terms and conditions.
    </asp:CustomValidator>

<asp:CheckBox ID="chkAge" runat="server" />
<asp:Label AssociatedControlID="chkAge" runat="server">I certify that I am at least 18 years of age.</asp:Label>        
<asp:CustomValidator ID="chkAgeValidator" runat="server" Display="Dynamic"
    ClientValidationFunction="checkAge">
    You must be 18 years or older to continue.
    </asp:CustomValidator>

And the codebehind:

Protected Sub chkAgreeValidator_ServerValidate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ServerValidateEventArgs) _
Handles chkAgreeValidator.ServerValidate
    e.IsValid = chkAgree.Checked
End Sub

Protected Sub chkAgeValidator_ServerValidate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ServerValidateEventArgs) _
Handles chkAgeValidator.ServerValidate
    e.IsValid = chkAge.Checked
End Sub

Windows comes with the netstat utility, which should do exactly what you want.

But now it is not working and I contacted our hosting team then they told me to use smtp

Newsflash - it was using SMTP before. They've not provided you with the information you need to solve the problem - or you've not relayed it accurately here.

Its possible that they've disabled the local MTA on the webserver, in which case you'll need to connect the SMTP port on a remote machine. There are lots of toolkits which will do the heavy lifting for you. Personally I like phpmailer because it adds other functionality.

Certainly if they've taken away a facility which was there before and your paying for a service then your provider should be giving you better support than that (there are also lots of programs to drop in in place of a full MTA which would do the job).

C.

My.ini from the file #password and #bind-address="127.0.0.1" are commented change the password to root and uncomment bind-address="127.0.0.1" and from the file cds.php change the

mysql_connect("localhost", "root", ""); to
mysql_connect("localhost", "root", "root");

Stop the Mysql services and try login again it got logged in.

For better output format check this command:

ps -fC java

Maybe worth looking at QRGen, which is built on top of ZXing and supports UTF-8 with this kind of syntax:

// if using special characters don't forget to supply the encoding
VCard johnSpecial = new VCard("Jöhn D?e")
                        .setAdress("ëåäö? Sträät 1, 1234 Döestüwn");
QRCode.from(johnSpecial).withCharset("UTF-8").file();

git push <repository> -d <branch>

to get the repository, type git remote -v in command line

1.this is my answer for your problem.

.ModalCarrot::before {
content:'';
background: url('blackCarrot.png'); /*url of image*/
height: 16px; /*height of image*/
width: 33px;  /*width of image*/
position: absolute;
}

you should use this

del record[-1]

The problem with

record = record[:-1]

Is that it makes a copy of the list every time you remove an item, so isn't very efficient

This is nothing to do with hardware nor software. Simply that RGB are the 3 primary colours which can be combined in various ways to produce every other colour. It is more about the human convention/perception of colours which carried over.

To list mongodb database on shell

 show databases     //Print a list of all available databases.
 show dbs   // Print a list of all databases on the server.

Few more basic commands

use <db>    // Switch current database to <db>. The mongo shell variable db is set to the current database.
show collections    //Print a list of all collections for current database.
show users  //Print a list of users for current database.

The answer by Steve Jessop explains well, why you can't use std::map::operator[] on a const std::map. Gabe Rainbow's answer suggests a nice alternative. I'd just like to provide some example code on how to use map::at(). So, here is an enhanced example of your function():

void function(const MAP &map, const std::string &findMe) {
    try {
        const std::string& value = map.at(findMe);
        std::cout << "Value of key \"" << findMe.c_str() << "\": " << value.c_str() << std::endl;
        // TODO: Handle the element found.
    }
    catch (const std::out_of_range&) {
        std::cout << "Key \"" << findMe.c_str() << "\" not found" << std::endl;
        // TODO: Deal with the missing element.
    }
}

And here is an example main() function:

int main() {
    MAP valueMap;
    valueMap["string"] = "abc";
    function(valueMap, "string");
    function(valueMap, "strong");
    return 0;
}

Output:

Value of key "string": abc
Key "strong" not found

If you must have a UITextField with 2 lines of text, one option is to add a UILabel as a subview of the UITextField for the second line of text. I have a UITextField in my app that users often do not realize is editable by tapping, and I wanted to add some small subtitle text that says "Tap to Edit" to the UITextField.

CGFloat tapLlblHeight = 10;
UILabel *tapEditLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, textField.frame.size.height - tapLlblHeight - 2, 70, tapLlblHeight)];
tapEditLbl.backgroundColor = [UIColor clearColor];
tapEditLbl.textColor = [UIColor whiteColor];
tapEditLbl.text = @"Tap to Edit";

[textField addSubview:tapEditLbl];

You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.

Python 3

In Python 3, this question doesn't apply. The plain int type is unbounded.

However, you might actually be looking for information about the current interpreter's word size, which will be the same as the machine's word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the maximum value representable by a signed word. Equivalently, it's the size of the largest possible list or in-memory sequence.

Generally, the maximum value representable by an unsigned word will be sys.maxsize * 2 + 1, and the number of bits in a word will be math.log2(sys.maxsize * 2 + 2). See this answer for more information.

Python 2

In Python 2, the maximum value for plain int values is available as sys.maxint:

>>> sys.maxint
9223372036854775807

You can calculate the minimum value with -sys.maxint - 1 as shown here.

Python seamlessly switches from plain to long integers once you exceed this value. So most of the time, you won't need to know it.
