In my case there was a corrupted character in one of the named params ("-StorageAccountName" for cmdlet "Get-AzureStorageKey") which showed as perfectly normal in my editor (SublimeText) but Windows Powershell couldn't parse it.

To get to the bottom of it, I moved the offending lines from the error message into another .ps1 file, ran that, and the error now showed a botched character at the beginning of my "-StorageAccountName" parameter.

Deleting the character (again which looks normal in the actual editor) and re-typing it fixes this issue.

Once you used

stmt->execute();

You MAY close it to use another query.

stmt->close();

This problem was hunting me for hours. Hopefully, it will fix yours.

Arrays should only have entries with numerical keys (arrays are also objects but you really should not mix these).

If you convert an array to JSON, the process will only take numerical properties into account. Other properties are simply ignored and that's why you get an empty array as result. Maybe this more obvious if you look at the length of the array:

> AssocArray.length
0

What is often referred to as "associative array" is actually just an object in JS:

var AssocArray = {};  // <- initialize an object, not an array
AssocArray["a"] = "The letter A"

console.log("a = " + AssocArray["a"]); // "a = The letter A"
JSON.stringify(AssocArray); // "{"a":"The letter A"}"

Properties of objects can be accessed via array notation or dot notation (if the key is not a reserved keyword). Thus AssocArray.a is the same as AssocArray['a'].

This issue has been recently fixed (Nov 2010) by Google, see https://code.google.com/p/analytics-issues/issues/detail?id=671. But be aware that as a good fix it brings more bugs :)

You will also have to follow the initialisation method listed here: https://developers.google.com/analytics/devguides/collection/ios/v2.

The latest instructions are going to give you a headache because it references utilities not included in the pod. Below will fail with the cocoapod

In case of circle all you need is one div, but in case of hollow square you need to have 2 divs. The divs are having a display of inline-block which you can change accordingly. Live Codepen link: Click Me

In case of circle all you need to change is the border properties and the dimensions(width and height) of circle. If you want to change color just change the border color of hollow-circle.

In case of the square background-color property needs to be changed depending upon the background of page or the element upon which you want to place the hollow-square. Always keep the inner-circle dimension small as compared to the hollow-square. If you want to change color just change the background-color of hollow-square. The inner-circle is centered upon the hollow-square using the position, top, left, transform properties just don't mess with them.

Code is as follows:

/* CSS Code */_x000D_

I had to add the .classpath too, form a java project. I made a dummy java project and looked in the workspace for this dummy java project to see what is required. I transferred the two files. profile and .claspath to my checked out, and disconnected source from my subversion server. From then on it turned to a java project from just a plain old project.

This very helpful feature is now available starting at version 1.1.2 of AngularJS. It's considered unstable but I have used it (1.1.3) and it works fine.

Basically you can use a function to generate a templateUrl string. The function is passed the route parameters that you can use to build and return the templateUrl string.

var app = angular.module('app',[]);

app.config(
    function($routeProvider) {
        $routeProvider.
            when('/', {templateUrl:'/home'}).
            when('/users/:user_id', 
                {   
                    controller:UserView, 
                    templateUrl: function(params){ return '/users/view/' + params.user_id; }
                }
            ).
            otherwise({redirectTo:'/'});
    }
);

TO collect all item of an array and return a json object

collectData: function (arrayElements) {

        var main = [];

        for (var i = 0; i < arrayElements.length; i++) {
            var data = {};
            this.e = arrayElements[i];            
            data.text = arrayElements[i].text;
            data.val = arrayElements[i].value;
            main[i] = data;
        }
        return main;
    },

TO parse the same data we go through like this

dummyParse: function (json) {       
        var o = JSON.parse(json); //conerted the string into JSON object        
        $.each(o, function () {
            inner = this;
            $.each(inner, function (index) {
                alert(this.text)
            });
        });

}

This an example from my code how to address a widget(button) in popupwindow

View v=LayoutInflater.from(getContext()).inflate(R.layout.popupwindow, null, false);
    final PopupWindow pw = new PopupWindow(v,500,500, true);
    final Button button = rootView.findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            pw.showAtLocation(rootView.findViewById(R.id.constraintLayout), Gravity.CENTER, 0, 0);


        }
    });
    final Button popup_btn=v.findViewById(R.id.popupbutton);

    popup_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            popup_btn.setBackgroundColor(Color.RED);
        }
    });

Hope this help you

You could also use clip-path to clip (hide) all overflowing edges but the one you want to show:

.shadow {
  box-shadow: 0 4px 4px black;
  clip-path: polygon(0 0, 100% 0, 100% 200%, 0 200%);
}

See clip-path (MDN). The arguments to polygon are the top-left point, the top-right point, the bottom-right point, and the bottom-left point. By setting the bottom edge to 200% (or whatever number bigger than 100%) you constrain your overflow to only the bottom edge.

Examples:

.shadow {
  box-shadow: 0 0 8px 5px rgba(200, 0, 0, 0.5);
}
.shadow-top {
  clip-path: polygon(0% -20%, 100% -20%, 100% 100%, 0% 100%);
}
.shadow-right {
  clip-path: polygon(0% 0%, 120% 0%, 120% 100%, 0% 100%);
}
.shadow-bottom {
  clip-path: polygon(0% 0%, 100% 0%, 100% 120%, 0% 120%);
}
.shadow-left {
  clip-path: polygon(-20% 0%, 100% 0%, 100% 100%, -20% 100%);
}

.shadow-bottom-right {
  clip-path: polygon(0% 0%, 120% 0%, 120% 120%, 0% 120%);
}

/* layout for example */
.box {
  display: inline-block;
  vertical-align: top;
  background: #338484;
  color: #fff;
  width: 4em;
  height: 2em;
  margin: 1em;
  padding: 1em;
}

<div class="box">none</div>
<div class="box shadow shadow-all">all</div>
<div class="box shadow shadow-top">top</div>
<div class="box shadow shadow-right">right</div>
<div class="box shadow shadow-bottom">bottom</div>
<div class="box shadow shadow-left">left</div>

Error 4 means "The cause was a user-mode read resulting in no page being found.". There's a tool that decodes it here.

Here's the definition from the kernel. Keep in mind that 4 means that bit 2 is set and no other bits are set. If you convert it to binary that becomes clear.

/*
 * Page fault error code bits
 *      bit 0 == 0 means no page found, 1 means protection fault
 *      bit 1 == 0 means read, 1 means write
 *      bit 2 == 0 means kernel, 1 means user-mode
 *      bit 3 == 1 means use of reserved bit detected
 *      bit 4 == 1 means fault was an instruction fetch
 */
#define PF_PROT         (1<<0)
#define PF_WRITE        (1<<1)
#define PF_USER         (1<<2)
#define PF_RSVD         (1<<3)
#define PF_INSTR        (1<<4)

Now then, "ip 00007f9bebcca90d" means the instruction pointer was at 0x00007f9bebcca90d when the segfault happened.

"libQtWebKit.so.4.5.2[7f9beb83a000+f6f000]" tells you:

• The object the crash was in: "libQtWebKit.so.4.5.2"
• The base address of that object "7f9beb83a000"
• How big that object is: "f6f000"

If you take the base address and subtract it from the ip, you get the offset into that object:

0x00007f9bebcca90d - 0x7f9beb83a000 = 0x49090D

Then you can run addr2line on it:

addr2line -e /usr/lib64/qt45/lib/libQtWebKit.so.4.5.2 -fCi 0x49090D

??:0

In my case it wasn't successful, either the copy I installed isn't identical to yours, or it's stripped.

Try this.

if(is_array($value) || is_object($value)){
    foreach($value as $item){
     //somecode
    }
}

The answer given by Jeff Paulsen is correct but the Comprarer can be much simplified to this:

public class SemiNumericComparer: IComparer<string>
{
    public int Compare(string s1, string s2)
    {
        if (IsNumeric(s1) && IsNumeric(s2))
          return Convert.ToInt32(s1) - Convert.ToInt32(s2)

        if (IsNumeric(s1) && !IsNumeric(s2))
            return -1;

        if (!IsNumeric(s1) && IsNumeric(s2))
            return 1;

        return string.Compare(s1, s2, true);
    }

    public static bool IsNumeric(object value)
    {
        int result;
        return Int32.TryParse(value, out result);
    }
}

This works because the only thing that is checked for the result of the Comparer is if the result is larger, smaller or equal to zero. One can simply subtract the values from another and does not have to handle the return values.

Also the IsNumeric method should not have to use a try-block and can benefit from TryParse.

And for those who are not sure: This Comparer will sort values so, that non numeric values are always appended to the end of the list. If one wants them at the beginning the second and third if block have to be swapped.

You can use also in the php file like this

<?php ini_set('upload_max_filesize', '200M'); ?>

Try this:

@echo off
set run=
tasklist /fi "imagename eq notepad.exe" | find ":" > nul
if errorlevel 1 set run=yes
if "%run%"=="yes" echo notepad is running
if "%run%"=="" echo notepad is not running
pause

As of https://github.com/dotnet/coreclr/pull/14863, there is a new way to generate hash codes that is super simple! Just write

public override int GetHashCode()
    => HashCode.Combine(field1, field2, field3);

This will generate a quality hash code without you having to worry about the implementation details.

TL;DR

The difference between the commands is that one provides you with a tag message while the other doesn't. An annotated tag has a message that can be displayed with git-show(1), while a tag without annotations is just a named pointer to a commit.

More About Lightweight Tags

According to the documentation: "To create a lightweight tag, don’t supply any of the -a, -s, or -m options, just provide a tag name". There are also some different options to write a message on annotated tags:

• When you use git tag <tagname>, Git will create a tag at the current revision but will not prompt you for an annotation. It will be tagged without a message (this is a lightweight tag).
• When you use git tag -a <tagname>, Git will prompt you for an annotation unless you have also used the -m flag to provide a message.
• When you use git tag -a -m <msg> <tagname>, Git will tag the commit and annotate it with the provided message.
• When you use git tag -m <msg> <tagname>, Git will behave as if you passed the -a flag for annotation and use the provided message.

Basically, it just amounts to whether you want the tag to have an annotation and some other information associated with it or not.

What are you using to compile this? If there's an undefined reference error, usually it's because the .o file (which gets created from the .cpp file) doesn't exist and your compiler/build system is not able to link it.

Also, in your card.cpp, the function should be Card::Card() instead of void Card. The Card:: is scoping; it means that your Card() function is a member of the Card class (which it obviously is, since it's the constructor for that class). Without this, void Card is just a free function. Similarly,

void Card(Card::Rank rank, Card::Suit suit)

should be

Card::Card(Card::Rank rank, Card::Suit suit)

Also, in deck.cpp, you are saying #include "Deck.h" even though you referred to it as deck.h. The includes are case sensitive.

You can use Map.

• A new data structure introduced in JavaScript ES6.
• Alternative to JavaScript Object for storing key/value pairs.
• Has useful methods for iteration over the key/value pairs.

var map = new Map();
map.set('name', 'John');
map.set('id', 11);

// Get the full content of the Map
console.log(map); // Map { 'name' => 'John', 'id' => 11 }

Get value of the Map using key

console.log(map.get('name')); // John 
console.log(map.get('id')); // 11

Get size of the Map

console.log(map.size); // 2

Check key exists in Map

console.log(map.has('name')); // true
console.log(map.has('age')); // false

Get keys

console.log(map.keys()); // MapIterator { 'name', 'id' }

Get values

console.log(map.values()); // MapIterator { 'John', 11 }

Get elements of the Map

for (let element of map) {
  console.log(element);
}

// Output:
// [ 'name', 'John' ]
// [ 'id', 11 ]

Print key value pairs

for (let [key, value] of map) {
  console.log(key + " - " + value);
}

// Output: 
// name - John
// id - 11

Print only keys of the Map

for (let key of map.keys()) {
  console.log(key);
}

// Output:
// name
// id

Print only values of the Map

for (let value of map.values()) {
  console.log(value);
}

// Output:
// John
// 11

Simple node script to get you going without too much hassle. Using readline to combine outputs so the lines don't get mangled.

const { spawn } = require('child_process');
const readline = require('readline');

  spawn('npm', ['run', 'start-watch']),
  spawn('npm', ['run', 'wp-server'])
].forEach(child => {
    readline.createInterface({
        input: child.stdout
    }).on('line', console.log);

    readline.createInterface({
        input: child.stderr,
    }).on('line', console.log);
});

If you want to snap particular running Windows app you’ll have to acquire a handle by looping over all open windows in your system.

It’s easier if you can open this app from Python script. Then you can convert process pid into window handle.

Another challenge is to snap the app that runs in particular monitor. I have 3 monitor system and I had to figure out how to snap display 2 and 3.

This example will take multiple application snapshots and save them into JPEG files.

import wx

print(wx.version())
app=wx.App()  # Need to create an App instance before doing anything
dc=wx.Display.GetCount()
print(dc)
#e(0)
displays = (wx.Display(i) for i in range(wx.Display.GetCount()))
sizes = [display.GetGeometry().GetSize() for display in displays]

for (i,s) in enumerate(sizes):
    print("Monitor{} size is {}".format(i,s))   
screen = wx.ScreenDC()
#pprint(dir(screen))
size = screen.GetSize()

print("Width = {}".format(size[0]))
print("Heigh = {}".format(size[1]))

width=size[0]
height=size[1]
x,y,w,h =putty_rect

bmp = wx.Bitmap(w,h)
mem = wx.MemoryDC(bmp)

for i in range(98):
    if 1:
        #1-st display:

        #pprint(putty_rect)
        #e(0)

        mem.Blit(-x,-y,w+x,h+y, screen, 0,0)

    if 0:
        #2-nd display:
        mem.Blit(0, 0, x,y, screen, width,0)
    #e(0)

    if 0:
        #3-rd display:
        mem.Blit(0, 0, width, height, screen, width*2,0)

    bmp.SaveFile(os.path.join(home,"image_%s.jpg" % i), wx.BITMAP_TYPE_JPEG)    
    print (i)
    sleep(0.2)
del mem

You can always fall back to the good old WinAPI calls, although the amount of work involved is non-trivial. There is no requirement that .NET services be installed via a .NET-aware mechanism.

To install:

• Open the service manager via OpenSCManager.
• Call CreateService to register the service.
• Optionally call ChangeServiceConfig2 to set a description.
• Close the service and service manager handles with CloseServiceHandle.

To uninstall:

• Open the service manager via OpenSCManager.
• Open the service using OpenService.
• Delete the service by calling DeleteService on the handle returned by OpenService.
• Close the service and service manager handles with CloseServiceHandle.

The main reason I prefer this over using the ServiceInstaller/ServiceProcessInstaller is that you can register the service with your own custom command line arguments. For example, you might register it as "MyApp.exe -service", then if the user runs your app without any arguments you could offer them a UI to install/remove the service.

Running Reflector on ServiceInstaller can fill in the details missing from this brief explanation.

P.S. Clearly this won't have "the same effect as calling: InstallUtil MyService.exe" - in particular, you won't be able to uninstall using InstallUtil. But it seems that perhaps this wasn't an actual stringent requirement for you.

Using advanced wheres:

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) {
          $q->where('Cab', 2)
            ->orWhere('Cab', 4);
      })
      ->get();

Or, even better, using whereIn():

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->whereIn('Cab', $cabIds)
      ->get();

Kotlin

Based on Suragch's answer, here is an elegant way using View extension:

fun View.slideUp(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, this.height.toFloat(), 0f)
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

fun View.slideDown(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, 0f, this.height.toFloat())
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

And then wherever you want to use it, you just need myView.slideUp() or myView.slideDown()

Since others have already mentioned all the possible solutions, I am sharing my workaround solution.

In my situation with Postgres 9.4, while working with Jackson,

//Convert it to named native query.
List<String> list = em.createNativeQuery("select cast(array_to_json(array_agg(row_to_json(a))) as text) from myschema.actors a")
                   .getResultList();

List<ActorProxy> map = new ObjectMapper().readValue(list.get(0), new TypeReference<List<ActorProxy>>() {});

I am sure you can find same for other databases.

Also FYI, JPA 2.0 native query results as map

you can use sorted() method if you want it to return the sorted list. It's more convenient.

l1 = []
n = int(input())

for i in range(n):
  user = int(input())
  l1.append(user)
sorted(l1,reverse=True)

list.sort() method modifies the list in-place and returns None.

if you still want to use sort you can do this.

l1 = []
n = int(input())

for i in range(n):
  user = int(input())
  l1.append(user)
l1.sort(reverse=True)
print(l1)

If you want to rule out any problems with the else part, try removing the else and place the command on a new line. Like this:

IF EXIST D:\RPS_BACKUP\backups_temp\ goto tempexists
goto tempexistscontinue  

the proper way is:

.attr({target:'nw', title:'Opens in a new window'})

you can show one line output then set property Line=0 and show multiple line output then set property Line=1 and more

[self.yourLableName sizeToFit];

You can use

.floatybox {
     display: inline-block;
     width: 123px;
}

If you only need to support browsers that have support for inline blocks. Inline blocks can have width, but are inline, like button elements.

Oh, and you might wnat to add vertical-align: top on the elements to make sure things line up

I've used a technique similar to McVitie's, and only in stored procedures or scripts that are pretty long. I will break down certain functional portions like this:

BEGIN /** delete queries **/

DELETE FROM blah_blah

END /** delete queries **/

BEGIN /** update queries **/

UPDATE sometable SET something = 1

END /** update queries **/

This method shows up fairly nice in management studio and is really helpful in reviewing code. The collapsed piece looks sort of like:

BEGIN /** delete queries **/ ... /** delete queries **/

I actually prefer it this way because I know that my BEGIN matches with the END this way.

Yes! The HTML5 audio tag with the "controls" attribute uses the browser's default player. You can customize it to your liking by not using the browser controls, but rolling your own controls and talking to the audio API via javascript.

Luckily, other people have already done this. My favorite player right now is jPlayer, it is very stylable and works great. Check it out.

I found an easy way to do this -

Just enter a command like this -

>mvn -Dtest=TestClassName#methodname -Dmaven.surefire.debug test

It will start listening to 5005 port. Now just create a remote debugging in Eclipse through Debug Configurations for localhost(any host) and port 5005.

Short version of Franci's answer:

for(Iterator<String> iter = json.keys();iter.hasNext();) {
    String key = iter.next();
    ...
}

You can't call a non-static method without first creating an instance of its parent class.

So from the static method, you would have to instantiate a new object...

Vehicle myCar = new Vehicle();

... and then call the non-static method.

myCar.Drive();

It's worth to mention that using concerns is considered bad idea by many.

1. like this guy
2. and this one

Some reasons:

1. There is some dark magic happening behind the scenes - Concern is patching include method, there is a whole dependency handling system - way too much complexity for something that's trivial good old Ruby mixin pattern.
2. Your classes are no less dry. If you stuff 50 public methods in various modules and include them, your class still has 50 public methods, it's just that you hide that code smell, sort of put your garbage in the drawers.
3. Codebase is actually harder to navigate with all those concerns around.
4. Are you sure all members of your team have same understanding what should really substitute concern?

Concerns are easy way to shoot yourself in the leg, be careful with them.

I've found that the above solution will not work if you have to deal with control characters like 02 (STX) or 03 (ETX), anything under 10 will be read as a single digit and throw off everything after. I ran into this problem trying to parse through serial communications. So, I first took the hex string received and put it in a buffer object then converted the hex string into an array of the strings like so:

buf = Buffer.from(data, 'hex');
l = Buffer.byteLength(buf,'hex');
for (i=0; i<l; i++){

    char = buf.toString('hex', i, i+1);
    msgArray.push(char);

}

Then .join it

message = msgArray.join('');

then I created a hexToAscii function just like in @Delan Azabani's answer above...

function hexToAscii(str){
    hexString = str;
    strOut = '';
        for (x = 0; x < hexString.length; x += 2) {
            strOut += String.fromCharCode(parseInt(hexString.substr(x, 2), 16));
        }
    return strOut;    
}

then called the hexToAscii function on 'message'

message = hexToAscii(message);

This approach also allowed me to iterate through the array and slice into the different parts of the transmission using the control characters so I could then deal with only the part of the data I wanted. Hope this helps someone else!

I'd suggest the question you should be asking is how to inject services into controllers. Fat services with skinny controllers is a good rule of thumb, aka just use controllers to glue your service/factory (with the business logic) into your views.

Controllers get garbage collected on route changes, so for example, if you use controllers to hold business logic that renders a value, your going to lose state on two pages if the app user clicks the browser back button.

var app = angular.module("testApp", ['']);

app.factory('methodFactory', function () {
    return { myMethod: function () {
            console.log("methodFactory - myMethod");
    };
};

app.controller('TestCtrl1', ['$scope', 'methodFactory', function ($scope,methodFactory) {  //Comma was missing here.Now it is corrected.
    $scope.mymethod1 = methodFactory.myMethod();
}]);

app.controller('TestCtrl2', ['$scope', 'methodFactory', function ($scope, methodFactory) {
    $scope.mymethod2 = methodFactory.myMethod();
}]);

Here is a working demo of factory injected into two controllers

Also, I'd suggest having a read of this tutorial on services/factories.

MS SQL connect to php

1. Install the drive from microsoft link https://www.microsoft.com/en-us/download/details.aspx?id=20098

2. After install you will get some files. Store it in your system temp folder

3. Check your php version , thread or non thread , and window bit - 32 or 64 (Thread or non thread , this is get you by phpinfo() )

4. According to your system & xampp configration (php version and all ) copy 2 files (php_sqlsrv & php_pdo_sqlsrv) to xampp/php/ext folder .

5. Add to php.ini file extension=php_sqlsrv_72_ts_x64 (php_sqlsrv_72_ts_x64.dll is your file which your copy in 4th step ) extension=php_pdo_sqlsrv_72_ts_x64 (php_pdo_sqlsrv_72_ts_x64.dll is your file which your copy in 4th step )

6. Next Php Code

   $serverName ="DESKTOP-me\MSSQLSERVER01"; (servername\instanceName)

   // Since UID and PWD are not specified in the $connectionInfo array, // The connection will be attempted using Windows Authentication.

   $connectionInfo = array("Database"=>"testdb","CharacterSet"=>"UTF-8");

   $conn = sqlsrv_connect( $serverName, $connectionInfo);

   if( $conn ) { //echo "Connection established.
   "; }else{ echo "Connection could not be established.
   "; die( print_r( sqlsrv_errors(), true)); }

   //$sql = "INSERT INTO dbo.master ('name') VALUES ('test')"; $sql = "SELECT * FROM dbo.master"; $stmt = sqlsrv_query( $conn, $sql );

   while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) { echo $row['id'].", ".$row['name']."
   "; }

   sqlsrv_free_stmt( $stmt);

if all things were said didn't work, go back to basics and test if this is working:

<html>
  <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
  </head>
  <body>
    <script type="text/javascript">
      $('body').click(function() {
        // do something here like:
        alert('hey! The body click is working!!!')
      });
    </script>
  </body>
</html>

then tell me if its working or not.

This works in IE without even having to declare a var for the table and will delete all rows:

for(var i = 0; i < resultsTable.rows.length;)
{   
   resultsTable.deleteRow(i);
}

The site generates a unique token when it makes the form page. This token is required to post/get data back to the server.

Since the token is generated by your site and provided only when the page with the form is generated, some other site can't mimic your forms -- they won't have the token and therefore can't post to your site.

Use sorted TreeMap:

Map<String, Float> map = new TreeMap<>(yourMap);

It will automatically put entries sorted by keys. I think natural String ordering will be fine in your case.

Note that HashMap due to lookup optimizations does not preserve order.

You can set timeouts for all connections made from the jvm by changing the following System-properties:

System.setProperty("sun.net.client.defaultConnectTimeout", "10000");
System.setProperty("sun.net.client.defaultReadTimeout", "10000");

Every connection will time out after 10 seconds.

Setting 'defaultReadTimeout' is not needed, but shown as an example if you need to control reading.

If you want to wait for jobs to finish, use wait. This will make the shell wait until all background jobs complete. However, if any of your jobs daemonize themselves, they are no longer children of the shell and wait will have no effect (as far as the shell is concerned, the child is already done. Indeed, when a process daemonizes itself, it does so by terminating and spawning a new process that inherits its role).

#!/bin/sh
{ sleep 5; echo waking up after 5 seconds; } &
{ sleep 1; echo waking up after 1 second; } &
wait
echo all jobs are done!

If you want to simply access a global variable you just use its name. However to change its value you need to use the global keyword.

E.g.

global someVar
someVar = 55

This would change the value of the global variable to 55. Otherwise it would just assign 55 to a local variable.

The order of function definition listings doesn't matter (assuming they don't refer to each other in some way), the order they are called does.

To avoid the "however" in Erandac's answer in combination of Daniel's and Salman's answers, one may use one of the following "partition workarounds"

SELECT customerID, myDate

  -- partition ranking works only with CTE / from MySQL 8.0 on
  , RANK() OVER (PARTITION BY customerID ORDER BY dateFrom) AS rank, 

  -- Erandac's method in combination of Daniel's and Salman's
  -- count all items in sequence, maximum reaches row count.
  , IF(customerID=@_lastRank, @_curRank:=@_curRank, @_curRank:=@_sequence+1) AS sequenceRank
  , @_sequence:=@_sequence+1 as sequenceOverAll

  -- Dense partition ranking, works also with MySQL 5.7
  -- remember to set offset values in from clause
  , IF(customerID=@_lastRank, @_nxtRank:=@_nxtRank, @_nxtRank:=@_nxtRank+1 ) AS partitionRank
  , IF(customerID=@_lastRank, @_overPart:=@_overPart+1, @_overPart:=1 ) AS partitionSequence

  , @_lastRank:=customerID
FROM myCustomers, 
  (SELECT @_curRank:=0, @_sequence:=0, @_lastRank:=0, @_nxtRank:=0, @_overPart:=0 ) r
ORDER BY customerID, myDate

The partition ranking in the 3rd variant in this code snippet will return continous ranking numbers. this will lead to a data structur similar to the rank() over partition by result. As an example, see below. In particular, the partitionSequence will always start with 1 for each new partitionRank, using this method:

customerID    myDate   sequenceRank (Erandac)
                          |    sequenceOverAll
                          |     |   partitionRank
                          |     |     | partitionSequence
                          |     |     |    | lastRank

I think it's quite dangerous to rely on the order of the values in a enum and to assume that the first is always the default. This would be good practice if you are concerned about protecting the default value.

enum E
{
    Foo = 0, Bar, Baz, Quux
}

Otherwise, all it takes is a careless refactor of the order and you've got a completely different default.

inside the Android manifest file of your project, find the activity declaration of whose you want to fix the orientation and add the following piece of code ,

android:screenOrientation="landscape"

for landscape orientation and for portrait add the following code,

android:screenOrientation="portrait"

Use value instanceof YourClass

IF EXIST "somefile.txt" (
  IF EXIST "someotherfile.txt" (
    SET var="somefile.txt","someotherfile.txt"
  )
) ELSE (
  CALL :SUB
)
:SUB
ECHO Sorry... nothin' there.
GOTO:EOF

Is this feasible?

SETLOCAL ENABLEDELAYEDEXPANSION
IF EXIST "somefile.txt" (
  SET var="somefile.txt"
  IF EXIST "someotherfile.txt" (
    SET var=!var!,"someotherfile.txt"
  )
) ELSE (
  IF EXIST "someotherfile.txt" (
    SET var="someotherfile.txt"
  ) ELSE (
  GOTO:EOF
  )
)

This is not a function of Maven; it's a function of the compiler. Look closely; the information you're looking for is most likely in the following line.

If you are saying that your problem is how to left align the form labels, see if this helps:
http://jsfiddle.net/panchroma/8gYPQ/

Try changing the text-align left / right in the CSS

.form-horizontal .control-label{
    /* text-align:right; */
    text-align:left;
    background-color:#ffa;
}

Good luck!

You can't have optional arguments that default to a certain value in Java. The nearest thing to what you are talking about is java varargs whereby you can pass an arbitrary number of arguments (of the same type) to a method.

According to MSDN maxAllowedContentLength has type uint, its maximum value is 4,294,967,295 bytes = 3,99 gb

So it should work fine.

There are lot of GUI designers even like Eclipse plugins, just few of them could use both, Swing and SWT..

WindowBuilder Pro GUI Designer - eclipse marketplace

WindowBuilder Pro GUI Designer - Google code home page

and

Jigloo SWT/Swing GUI Builder - eclipse market place

The window builder is quite better tool..

But IMHO, GUIs created by those tools have really ugly and unmanageable code..

This function (ManagementQuery) works on Windows XP and later:

private static string ManagementQuery(string query, string parameter, string scope = null) {
    string result = string.Empty;
    var searcher = string.IsNullOrEmpty(scope) ? new ManagementObjectSearcher(query) : new ManagementObjectSearcher(scope, query);
    foreach (var os in searcher.Get()) {
        try {
            result = os[parameter].ToString();
        }
        catch {
            //ignore
        }

        if (!string.IsNullOrEmpty(result)) {
            break;
        }
    }

    return result;
}

Usage:

Console.WriteLine(BytesToMb(Convert.ToInt64(ManagementQuery("SELECT TotalPhysicalMemory FROM Win32_ComputerSystem", "TotalPhysicalMemory", "root\\CIMV2"))));

You can simply do this with help of AJAX... Here is a example which calls a python function which prints hello without redirecting or refreshing the page.

In app.py put below code segment.

#rendering the HTML page which has the button
@app.route('/json')
def json():
    return render_template('json.html')

#background process happening without any refreshing
@app.route('/background_process_test')
def background_process_test():
    print ("Hello")
    return ("nothing")

And your json.html page should look like below.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type=text/javascript>
        $(function() {
          $('a#test').on('click', function(e) {
            e.preventDefault()
            $.getJSON('/background_process_test',
                function(data) {
              //do nothing
            });
            return false;
          });
        });
</script>


//button
<div class='container'>
    <h3>Test</h3>
        <form>
            <a href=# id=test><button class='btn btn-default'>Test</button></a>
        </form>

</div>

Here when you press the button Test simple in the console you can see "Hello" is displaying without any refreshing.

$orderId = 1; // YOUR ORDER ID_x000D_
$items = $block->getOrderItems($orderId);_x000D_
 _x000D_
foreach ($items as $item) {_x000D_
    $options = $item->getProductOptions();        _x000D_
    if (isset($options['options']) && !empty($options['options'])) {        _x000D_
        foreach ($options['options'] as $option) {_x000D_
            echo 'Title: ' . $option['label'] . '<br />';_x000D_
            echo 'ID: ' . $option['option_id'] . '<br />';_x000D_
            echo 'Type: ' . $option['option_type'] . '<br />';_x000D_
            echo 'Value: ' . $option['option_value'] . '<br />' . '<br />';_x000D_
        }_x000D_
    }_x000D_
}

FWIW, htpasswd -n username will output the result directly to stdout, and avoid touching files altogether.

In python3, __init__.py is no longer necessary. If the current directory of the console is the directory where the python script is located, everything works fine with

import user

However, this won't work if called from a different directory, which does not contain user.py.
In that case, use

from . import user

This works even if you want to import the whole file instead of just a class from there.

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

I found a combination of jymdman's and Rahul Patil's answers is working best for me:

.mat-column-userId {
  flex: 0 0 75px;
}

Also, if you have one "leading" column which you want to always occupy a certain amount of space across different devices, I found the following quite handy to adopt to the available container width in a more responsive kind (this forces the remaining columns to use the remaining space evenly):

.mat-column-userName {
  flex: 0 0 60%;
}

Try looking at the java.awt.Robot class. It allows you to move the mouse programatically.

the command to get the effective push remote for the branch, e.g., master, is:

git config branch.master.pushRemote || git config remote.pushDefault || git config branch.master.remote

Here's why (from the "man git config" output):

branch.name.remote [...] tells git fetch and git push which remote to fetch from/push to [...] [for push] may be overridden with remote.pushDefault (for all branches) [and] for the current branch [..] further overridden by branch.name.pushRemote [...]

For some reason, "man git push" only tells about branch.name.remote (even though it has the least precedence of the three) + erroneously states that if it is not set, push defaults to origin - it does not, it's just that when you clone a repo, branch.name.remote is set to origin, but if you remove this setting, git push will fail, even though you still have the origin remote

If your code can sensibly be written as a case statement, this is pretty decent:

case mybool
when TrueClass, FalseClass
  puts "It's a bool!"
else
  puts "It's something else!"
end

According to the pytest docs, pytest --capture=sys should work. If you want to capture standard out inside a test, refer to the capsys fixture.

Engine must be before select:

CREATE TEMPORARY TABLE temp1 ENGINE=MEMORY 
as (select * from table1)

Basic error handling

If your test case runner returns a non-zero code for failed tests, you can simply write:

test_handler test_case_x; test_result=$?
if ((test_result != 0)); then
  printf '%s\n' "Test case x failed" >&2  # write error message to stderr
  exit 1                                  # or exit $test_result
fi

Or even shorter:

if ! test_handler test_case_x; then
  printf '%s\n' "Test case x failed" >&2
  exit 1
fi

Or the shortest:

test_handler test_case_x || { printf '%s\n' "Test case x failed" >&2; exit 1; }

To exit with test_handler's exit code:

test_handler test_case_x || { ec=$?; printf '%s\n' "Test case x failed" >&2; exit $ec; }

Advanced error handling

If you want to take a more comprehensive approach, you can have an error handler:

exit_if_error() {
  local exit_code=$1
  shift
  [[ $exit_code ]] &&               # do nothing if no error code passed
    ((exit_code != 0)) && {         # do nothing if error code is 0
      printf 'ERROR: %s\n' "$@" >&2 # we can use better logging here
      exit "$exit_code"             # we could also check to make sure
                                    # error code is numeric when passed
    }
}

then invoke it after running your test case:

run_test_case test_case_x
exit_if_error $? "Test case x failed"

or

run_test_case test_case_x || exit_if_error $? "Test case x failed"

The advantages of having an error handler like exit_if_error are:

• we can standardize all the error handling logic such as logging, printing a stack trace, notification, doing cleanup etc., in one place
• by making the error handler get the error code as an argument, we can spare the caller from the clutter of if blocks that test exit codes for errors
• if we have a signal handler (using trap), we can invoke the error handler from there

If it's worth adding another file / dependency to your project, I've just written a tiny little class that extends datetime.time with the ability to do arithmetic. If you go past midnight, it just wraps around:

>>> from nptime import nptime
>>> from datetime import timedelta
>>> afternoon = nptime(12, 24) + timedelta(days=1, minutes=36)
>>> afternoon
nptime(13, 0)
>>> str(afternoon)
'13:00:00'

It's available from PyPi as nptime ("non-pedantic time"), or on GitHub: https://github.com/tgs/nptime

The documentation is at http://tgs.github.io/nptime/

There are several ways to achieve this.

Probably the easiest would be to use JavaScript to change the form's action.

<input type="submit" value="SecondServlet" onclick="form.action='SecondServlet';">

But this of course won't work when the enduser has JS disabled (mobile browsers, screenreaders, etc).

Another way is to put the second button in a different form, which may or may not be what you need, depending on the concrete functional requirement, which is not clear from the question at all.

<form action="FirstServlet" method="Post">
    Last Name: <input type="text" name="lastName" size="20">
    <br><br>
    <input type="submit" value="FirstServlet">
</form>
<form action="SecondServlet" method="Post">
    <input type="submit"value="SecondServlet">
</form>

Note that a form would on submit only send the input data contained in the very same form, not in the other form.

Again another way is to just create another single entry point servlet which delegates further to the right servlets (or preferably, the right business actions) depending on the button pressed (which is by itself available as a request parameter by its name):

<form action="MainServlet" method="Post">
    Last Name: <input type="text" name="lastName" size="20">
    <br><br>
    <input type="submit" name="action" value="FirstServlet">
    <input type="submit" name="action" value="SecondServlet">
</form>

with the following in MainServlet

String action = request.getParameter("action");

if ("FirstServlet".equals(action)) {
    // Invoke FirstServlet's job here.
} else if ("SecondServlet".equals(action)) {
    // Invoke SecondServlet's job here.
}

This is only not very i18n/maintenance friendly. What if you need to show buttons in a different language or change the button values while forgetting to take the servlet code into account?

A slight change is to give the buttons its own fixed and unique name, so that its presence as request parameter could be checked instead of its value which would be sensitive to i18n/maintenance:

<form action="MainServlet" method="Post">
    Last Name: <input type="text" name="lastName" size="20">
    <br><br>
    <input type="submit" name="first" value="FirstServlet">
    <input type="submit" name="second" value="SecondServlet">
</form>

with the following in MainServlet

if (request.getParameter("first") != null) {
    // Invoke FirstServlet's job here.
} else if (request.getParameter("second") != null) {
    // Invoke SecondServlet's job here.
}

Last way would be to just use a MVC framework like JSF so that you can directly bind javabean methods to buttons, but that would require drastic changes to your existing code.

<h:form>
    Last Name: <h:inputText value="#{bean.lastName}" size="20" />
    <br/><br/>
    <h:commandButton value="First" action="#{bean.first}" />
    <h:commandButton value="Second" action="#{bean.Second}" />
</h:form>

with just the following javabean instead of a servlet

@ManagedBean
@RequestScoped
public class Bean {

    private String lastName; // +getter+setter

    public void first() {
        // Invoke original FirstServlet's job here.
    }

    public void second() {
        // Invoke original SecondServlet's job here.
    }

}

Delete the file(index.php) from your xampp folder, you will get the list of directories and files from htdocs folder.

FWIW, here is my approach = a simple one that works for me:

<div id="outerDivWrapper">
   <div id="outerDiv">
      <div id="scrollableContent">
blah blah blah
      </div>
   </div>
</div>

html, body {
   height: 100%;
   margin: 0em;
}

#outerDivWrapper, #outerDiv {
   height: 100%;
   margin: 0em;
}

#scrollableContent {
   height: 100%;
   margin: 0em;
   overflow-y: auto;
}

You can also use the PredicateBuilder from LinqKit to chain multiple typesafe lambda expressions using Or or And.

http://www.albahari.com/nutshell/predicatebuilder.aspx

The framework supports text-shadow but does not support text-outline. But there is a trick: shadow is something that is translucent and fades. Redraw the shadow a couple of times and all the alpha gets summed up and the result is an outline.

A very simple implementation extends TextView and overrides the draw(..) method. Every time a draw is requested our subclass does 5-10 drawings.

public class OutlineTextView extends TextView {

    // Constructors

    @Override
    public void draw(Canvas canvas) {
        for (int i = 0; i < 5; i++) {
            super.draw(canvas);
        }
    }

}


<OutlineTextView
    android:shadowColor="#000"
    android:shadowRadius="3.0" />

In general, when "Bad File Descriptor" is encountered, it means that the socket file descriptor you passed into the API is not valid, which has multiple possible reasons:

1. The fd is already closed somewhere.
2. The fd has a wrong value, which is inconsistent with the value obtained from socket() api

Not sure of the exact question but is this what you are looking for?

public class TestRun
{
     public static void main(String [] args)
     {
        Map<String, Integer[]> prices = new HashMap<String, Integer[]>();

        prices.put("milk", new Integer[] {1, 3, 2});
        prices.put("eggs", new Integer[] {1, 1, 2});
     }
}

Solution 1:

var AWS = require('aws-sdk');
var path = require("path");
var fs = require('fs');

const uploadDir = function(s3Path, bucketName) {

    let s3 = new AWS.S3({
    accessKeyId: process.env.S3_ACCESS_KEY,
    secretAccessKey: process.env.S3_SECRET_KEY
    });

    function walkSync(currentDirPath, callback) {
        fs.readdirSync(currentDirPath).forEach(function (name) {
            var filePath = path.join(currentDirPath, name);
            var stat = fs.statSync(filePath);
            if (stat.isFile()) {
                callback(filePath, stat);
            } else if (stat.isDirectory()) {
                walkSync(filePath, callback);
            }
        });
    }

    walkSync(s3Path, function(filePath, stat) {
        let bucketPath = filePath.substring(s3Path.length+1);
        let params = {Bucket: bucketName, Key: bucketPath, Body: fs.readFileSync(filePath) };
        s3.putObject(params, function(err, data) {
            if (err) {
                console.log(err)
            } else {
                console.log('Successfully uploaded '+ bucketPath +' to ' + bucketName);
            }
        });

    });
};

uploadDir("path to your folder", "your bucket name");

Solution 2:

aws s3 cp SOURCE_DIR s3://DEST_BUCKET/ --recursive

you can always convert your varchar-column to bigint as integer might be too short...

select cast([yourvarchar] as BIGINT)

but you should always care for alpha characters

where ISNUMERIC([yourvarchar] +'e0') = 1

the +'e0' comes from http://blogs.lessthandot.com/index.php/DataMgmt/DataDesign/isnumeric-isint-isnumber

this would lead to your statement

SELECT
  *
FROM
  Table
ORDER BY
   ISNUMERIC([yourvarchar] +'e0') DESC
 , LEN([yourvarchar]) ASC

the first sorting column will put numeric on top. the second sorts by length, so 10 will preceed 0001 (which is stupid?!)

this leads to the second version:

SELECT
      *
    FROM
      Table
    ORDER BY
       ISNUMERIC([yourvarchar] +'e0') DESC
     , RIGHT('00000000000000000000'+[yourvarchar], 20) ASC

the second column now gets right padded with '0', so natural sorting puts integers with leading zeros (0,01,10,0100...) in correct order (correct!) - but all alphas would be enhanced with '0'-chars (performance)

so third version:

 SELECT
          *
        FROM
          Table
        ORDER BY
           ISNUMERIC([yourvarchar] +'e0') DESC
         , CASE WHEN ISNUMERIC([yourvarchar] +'e0') = 1
                THEN RIGHT('00000000000000000000' + [yourvarchar], 20) ASC
                ELSE LTRIM(RTRIM([yourvarchar]))
           END ASC

now numbers first get padded with '0'-chars (of course, the length 20 could be enhanced) - which sorts numbers right - and alphas only get trimmed

I ran into the problem of not having set my sources root folder (project window--right click folder, mark directory as > sources root). If you don't set this IDEA doesn't parse the file.

private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivity(intent);
this.finish();

And then you can fetch it like this:

imageUri = Uri.parse(extras.getString("imageUri"));

There is an easy way

Instead of /pagename/ use index.php/pagename/ or if you don't use permalinks do the following :

Post

index.php?p=123

Page

index.php?page_id=42

Category

index.php?cat=7

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

After reading Paul's answer, I went on digging for more information on https://dev.mysql.com/doc/refman/5.7/en/query-log.html

I found a really useful code by a person. Here's the summary of the context.

(Note: The following code is not mine)

This script is an example to keep the table clean which will help you to reduce your table size. As after a day, there will be about 180k queries of log. ( in a file, it would be 30MB per day)

You need to add an additional column (event_unix) and then you can use this script to keep the log clean... it will update the timestamp into a Unix-timestamp, delete the logs older than 1 day and then update the event_time into Timestamp from event_unix... sounds a bit confusing, but it's working great.

Commands for the new column:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
ALTER TABLE `general_log_temp`
ADD COLUMN `event_unix` int(10) NOT NULL AFTER `event_time`;
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Cleanup script:

SET GLOBAL general_log = 'OFF';
RENAME TABLE general_log TO general_log_temp;
UPDATE general_log_temp SET event_unix = UNIX_TIMESTAMP(event_time);
DELETE FROM `general_log_temp` WHERE `event_unix` < UNIX_TIMESTAMP(NOW()) - 86400;
UPDATE general_log_temp SET event_time = FROM_UNIXTIME(event_unix);
RENAME TABLE general_log_temp TO general_log;
SET GLOBAL general_log = 'ON';

Credit goes to Sebastian Kaiser (Original writer of the code).

Hope someone will find it useful as I did.

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

An array "decays" into a pointer to its first element, so scanf("%s", string) is equivalent to scanf("%s", &string[0]). On the other hand, scanf("%s", &string) passes a pointer-to-char[256], but it points to the same place.

Then scanf, when processing the tail of its argument list, will try to pull out a char *. That's the Right Thing when you've passed in string or &string[0], but when you've passed in &string you're depending on something that the language standard doesn't guarantee, namely that the pointers &string and &string[0] -- pointers to objects of different types and sizes that start at the same place -- are represented the same way.

I don't believe I've ever encountered a system on which that doesn't work, and in practice you're probably safe. None the less, it's wrong, and it could fail on some platforms. (Hypothetical example: a "debugging" implementation that includes type information with every pointer. I think the C implementation on the Symbolics "Lisp Machines" did something like this.)

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

Let's start with a quote from the virtual machine spec:

Loading of a class or interface that contains a String literal may create a new String object (§2.4.8) to represent that literal. This may not occur if the a String object has already been created to represent a previous occurrence of that literal, or if the String.intern method has been invoked on a String object representing the same string as the literal.

This may not occur - This is a hint, that there's something special about String objects. Usually, invoking a constructor will always create a new instance of the class. This is not the case with Strings, especially when String objects are 'created' with literals. Those Strings are stored in a global store (pool) - or at least the references are kept in a pool, and whenever a new instance of an already known Strings is needed, the vm returns a reference to the object from the pool. In pseudo code, it may go like that:

1: a := "one" 
   --> if(pool[hash("one")] == null)  // true
           pool[hash("one") --> "one"]
       return pool[hash("one")]

2: b := "one" 
  --> if(pool[hash("one")] == null)   // false, "one" already in pool
        pool[hash("one") --> "one"]
      return pool[hash("one")] 

So in this case, variables a and b hold references to the same object. IN this case, we have (a == b) && (a.equals(b)) == true.

This is not the case if we use the constructor:

1: a := "one"
2: b := new String("one")

Again, "one" is created on the pool but then we create a new instance from the same literal, and in this case, it leads to (a == b) && (a.equals(b)) == false

So why do we have a String pool? Strings and especially String literals are widely used in typical Java code. And they are immutable. And being immutable allowed to cache String to save memory and increase performance (less effort for creation, less garbage to be collected).

As programmers we don't have to care much about the String pool, as long as we keep in mind:

• (a == b) && (a.equals(b)) may be true or false (always use equals to compare Strings)
• Don't use reflection to change the backing char[] of a String (as you don't know who is actualling using that String)

About horrible code:

int& getTheValue()
{
   return *new int;
}

So, indeed, memory pointer lost after return. But if you use shared_ptr like that:

int& getTheValue()
{
   std::shared_ptr<int> p(new int);
   return *p->get();
}

Memory not lost after return and will be freed after assignment.

vector.clear() is effectively the same as vector.erase( vector.begin(), vector.end() ).

If your problem is about calling delete for each pointer contained in your vector, try this:

#include <algorithm>

template< typename T >
struct delete_pointer_element
{
    void operator()( T element ) const
    {
        delete element;
    }
};

// ...
std::for_each( vector.begin(), vector.end(), delete_pointer_element<int*>() );

Edit: Code rendered obsolete by C++11 range-for.

And if you'd like to extract the differences between the two strings, you can use String::Diff.

If you didn't commit it to the master branch yet, its easy:

• get off the master branch (like git checkout -b oops/fluke/dang)
• commit your changes there (like git add -u; git commit;)
• go back the master branch (like git checkout master)

Your changes will be saved in branch oops/fluke/dang; master will be as it was.

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

You can simply write

hex(x)[2:]

to get the first two characters removed.

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

Generic:

ALTER TABLE table_name DROP COLUMN column_name;

In your case:

ALTER TABLE MEN DROP COLUMN Lname;

One other alternative is to use function name in #if. The #if will detect if the parameter is function and if it is then it will call it and use its return for truthyness check. Below myFunction gets current context as this.

{{#if myFunction}}
  I'm Happy!
{{/if}}

Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".

Start with finding out your PHP binary by typing in command line:

whereis php

The output should be something like:

php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

Specify correctly the full path in your command.

Type the following command to enter cronjob:

crontab -e

To see what you got in crontab.

EDIT 1:

To exit from vim editor without saving just click:

Shift+:

And then type q!

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

You control the access rights for members and functions using Private/Protected/Public right? so assuming the idea of each and every one of those 3 levels is clear, then it should be clear that we are missing something...

The declaration of a member/function as protected for example is pretty generic. You are saying that this function is out of reach for everyone (except for an inherited child of course). But what about exceptions? every security system lets you have some type of 'white list" right?

So friend lets you have the flexibility of having rock solid object isolation, but allows for a "loophole" to be created for things that you feel are justified.

I guess people say it is not needed because there is always a design that will do without it. I think it is similar to the discussion of global variables: You should never use them, There is always a way to do without them... but in reality, you see cases where that ends up being the (almost) most elegant way... I think this is the same case with friends.

It doesn't really do any good, other than let you access a member variable without using a setting function

well that is not exactly the way to look at it. The idea is to control WHO can access what, having or not a setting function has little to do with it.

If you don't want to use a function, you can use something like this

-- VIEW
CREATE VIEW [dbo].[vwPharmacyProducts]
AS
SELECT     PharmacyId, ProductId
FROM         dbo.Stock
WHERE     (TotalQty > 0)

-- Use of view inside a stored procedure
CREATE PROCEDURE [dbo].[usp_GetProductByFilter]
(   @pPharmacyId int ) AS

IF @pPharmacyId = 0 BEGIN SET @pPharmacyId = NULL END

SELECT  P.[ProductId], P.[strDisplayAs] FROM [Product] P
WHERE (P.[bDeleted] = 0)
    AND (P.[ProductId] IN (Select vPP.ProductId From vwPharmacyProducts vPP
                           Where vPP.PharmacyId = @pPharmacyId)
                       OR @pPharmacyId IS NULL
        )

Hope it will help

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

css3-mediaqueries-js is probably what you are looking for: this script emulates media queries. However (from the script's site) it "doesn't work on @imported stylesheets (which you shouldn't use anyway for performance reasons). Also won't listen to the media attribute of the <link> and <style> elements".

In the same vein you have the simpler Respond.js, which enables only min-width and max-width media queries.

There isn't one. If you really wanted to use the VB InputBox in C# you can. Just add reference to Microsoft.VisualBasic.dll and you'll find it there.

But I would suggest to not use it. It is ugly and outdated IMO.

If you run

cmake .

it will regenerate the CMake files. Which is necessary if you add a new file to a source folder that is selected by *.cc, for example.

While this isn't a "clean" per se, it does "clean" up the CMake files by regenerating the caches.

You can use boost::posix_time::time_duration to get the time range. E.g like this

boost::posix_time::time_duration diff = tick - now;
diff.total_milliseconds();

And to get a higher resolution you can change the clock you are using. For example to the boost::posix_time::microsec_clock, though this can be OS dependent. On Windows, for example, boost::posix_time::microsecond_clock has milisecond resolution, not microsecond.

An example which is a little dependent on the hardware.

int main(int argc, char* argv[])
{
    boost::posix_time::ptime t1 = boost::posix_time::second_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime t2 = boost::posix_time::second_clock::local_time();
    boost::posix_time::time_duration diff = t2 - t1;
    std::cout << diff.total_milliseconds() << std::endl;

    boost::posix_time::ptime mst1 = boost::posix_time::microsec_clock::local_time();
    boost::this_thread::sleep(boost::posix_time::millisec(500));
    boost::posix_time::ptime mst2 = boost::posix_time::microsec_clock::local_time();
    boost::posix_time::time_duration msdiff = mst2 - mst1;
    std::cout << msdiff.total_milliseconds() << std::endl;
    return 0;
}

On my win7 machine. The first out is either 0 or 1000. Second resolution. The second one is nearly always 500, because of the higher resolution of the clock. I hope that help a little.

step1:
class CNAME:
   ...
   def as_dict(self):
       return {item.name: getattr(self, item.name) for item in self.__table__.columns}

step2:
list = []
for data in session.query(CNAME).all():
    list.append(data.as_dict())

step3:
return jsonify(list)

I think the best way to do this with basic R is:

for( i in rownames(df) )
   print(df[i, "column1"])

The advantage over the for( i in 1:nrow(df))-approach is that you do not get into trouble if df is empty and nrow(df)=0.

Environment

My OS is Ubuntu 16.04 and jupyter is 4.3.0.

Method

First, i logged out jupyter at its homepage on browser(the logout button is at top-right)

Second, type in Ctrl + C in your terminal and it shows:

[I 15:59:48.407 NotebookApp]interrupted Serving notebooks from local directory: /home/Username 0 active kernels

The Jupyter Notebook is running at: http://localhost:8888/?token=a572c743dfb73eee28538f9a181bf4d9ad412b19fbb96c82

Shutdown this notebook server (y/[n])?

Last step, type in y within 5 sec, and if it shows:

[C 15:59:50.407 NotebookApp] Shutdown confirmed
[I 15:59:50.408 NotebookApp] Shutting down kernels

Congrats! You close your jupyter successfully.

You can add an alias to diff with its own pager with pager.alias, like so:

[alias]
  dc = diff
  dsc = diff --staged
[pager]
  dc = cat
  dsc = cat

This will keep the color on and use 'cat' as the pager when invoked at 'git dc'.

Also, things not to do:

• use --no-pager in your alias. Git (1.8.5.2, Apple Git-48) will complain that you are trying to modify the environment.
• use a shell with !sh or !git. This will bypass the environment error, above, but it will reset your working directory (for the purposes of this command) to the top-level Git directory, so any references to a local file will not work if you are already in a subdirectory of your repository.

I've played around with it and I think I have a solution. The following example shows how to set Box-Shadow so that it will only show a shadow for the inset top and bottom of an element.

Legend: insetOption leftPosition topPosition blurStrength spreadStrength color

Description
The key to accomplishing this is to set the blur value to <= the negative of the spread value (ex. inset 0px 5px -?px 5px #000; the blur value should be -5 and lower) and to also keep the blur value > 0 when subtracted from the primary positioning value (ex. using the example from above, the blur value should be -9 and up, thus giving us an optimal value for the the blur to be between -5 and -9).

Solution

.styleName {   
/* for IE 8 and lower */
background-color:#888; filter: progid:DXImageTransform.Microsoft.dropShadow(color=#FFFFCC, offX=0, offY=0, positive=true);  

/* for IE 9 */ 
box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7); 

/* for webkit browsers */ 
-webkit-box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7); 

/* for firefox 3.6+ */
-moz-box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7);   
}

Use the below code to convert a php array to CSV

<?php
   $ROW=db_export_data();//Will return a php array
   header("Content-type: application/csv");
   header("Content-Disposition: attachment; filename=test.csv");
   $fp = fopen('php://output', 'w');

   foreach ($ROW as $row) {
        fputcsv($fp, $row);
   }
   fclose($fp);

For users coming back to this post long after the initial answer was accepted, it may pay off to note that now you can use

data-fancybox-href="#" 

on any element (since data is an HTML-5 accepted attribute) to have the fancybox work on say an input form if for some reason you can't use the options to initiate for some reason (like say you have multiple elements on the page that use fancybox and they all share a similar class you call fancybox on).

First we'll consider loops where the number of iterations of the inner loop is independent of the value of the outer loop's index. For example:

 for (i = 0; i < N; i++) {
     for (j = 0; j < M; j++) {
         sequence of statements
      }
  }

The outer loop executes N times. Every time the outer loop executes, the inner loop executes M times. As a result, the statements in the inner loop execute a total of N * M times. Thus, the total complexity for the two loops is O(N2).

Right now with using Spring-Boot 2.0.4 - { } won't work.

@RequestMapping

still has String[] as a value parameter, so declaration looks like this:

 @RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)

** Update - Works With Spring-Boot 2.2**

 @RequestMapping(value={"/","/index","/login","/home"}, method = RequestMethod.GET)

Some precisions:

null and undefined are two different values. One is representing the absence of a value for a name and the other is representing the absence of a name.

What happens in an if goes as follows for if( o ):

The expression in the parentheses o is evaluated, and then the if kicks in type-coercing the value of the expression in the parentheses - in our case o.

Falsy (that will get coerced to false) values in JavaScript are: '', null, undefined, 0, and false.

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

ErrCatch()

Sub ErrCatch()
    Dim Res, CurrentStep

    On Error Resume Next

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

End Sub

Function UnSafeCode(Arg, ErrStep)

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

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

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

    ErrStep = 0
End Function

When a search engine spider finds 301 status code in the response header of a webpage, it understands that this webpage no longer exists, it searches for location header in response pick the new URL and replace the indexed URL with the new one and also transfer pagerank.

So search engine refreshes all indexed URL that no longer exist (301 found) with the new URL, this will retain your old webpage traffic, pagerank and divert it to the new one (you will not lose you traffic of old webpage).

Browser: if a browser finds 301 status code then it caches the mapping of the old URL with the new URL, the client/browser will not attempt to request the original location but use the new location from now on unless the cache is cleared.

When a search engine spider finds 302 status for a webpage, it will only redirect temporarily to the new location and crawl both of the pages. The old webpage URL still exists in the search engine database and it always attempts to request the old location and crawl it. The client/browser will still attempt to request the original location.

Read more about how to implement it in asp.net c# and what is the impact on search engines - http://www.dotnetbull.com/2013/08/301-permanent-vs-302-temporary-status-code-aspnet-csharp-Implementation.html

Try with JSToolNpp and follow the snap like this then Plugins | JSTool | JSFormat.

This will work

    a:hover, a:focus, a:active {
        outline: none;
    }

What this does is removes the outline for all the three pseudo-classes.

The solution is to copy your file ~/.android/adbkey.pub (on GNU/Linux, or %USERPROFILE%\.android\adbkey.pub on Windows) to Android, and place it as /data/misc/adb/adb_keys. You need root privileges to do that.

You can transfer the file any way you like (or are able to), be it USB, e-mail or a temporary file upload service. In my case, as it was a new Android-x86 installation in a Virtual Machine, no usable web browser, and with network/TCP adb not working, I had to actually type in the 715 characters.

At least it worked.

You can use Culture to get month name for your country like:

System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("ar-EG");
string FormatDate = DateTime.Now.ToString("dddd., MMM dd yyyy, hh:MM tt", culture);

why a[] doesn't equals b[]? Because equals function really called on Byte[] or byte[] is Object.equals(Object obj). This functions only compares object identify , don't compare the contents of the array.

hope this may help you:

SELECT  CAST(LoginTime AS DATE)
         FROM    AuditTrail 

If you want to have some filters over this datetime or it's different parts, you can use built-in functions such as Year and Month

If you want to have a new data frame then:

import pandas as pd
old = pd.DataFrame({'A' : [4,5], 'B' : [10,20], 'C' : [100,50], 'D' : [-30,-50]})
new=  old[['A', 'C', 'D']]

A subselect in the WHERE clause to retrieve the greatest BALANCE aggregated over all rows. If multiple ID values share that balance value, all would be returned.

SELECT

FROM CUSTOMERS
WHERE BALANCE = (SELECT MAX(BALANCE) FROM CUSTOMERS)

Bootstrap 3 now has Responsive tables out of the box. Hooray! :)

You can check it here: https://getbootstrap.com/docs/3.3/css/#tables-responsive

Add a <div class="table-responsive"> surrounding your table and you should be good to go:

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

To make it work on all layouts you can do this:

.table-responsive
{
    overflow-x: auto;
}

The simplest solution may be to add HINTS to each find_* request.

For example:

find_library(CURL_LIBRARY
    NAMES curl curllib libcurl_imp curllib_static
    HINTS "${CMAKE_PREFIX_PATH}/curl/lib"
)

For Boost I would strongly recommend using the FindBoost standard module and setting the BOOST_DIR variable to point to your Boost libraries.

I used the Visual Studio 2008 Uninstall tool and it worked fine for me.

You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Found here, on the MSDN Forum: MSDN forum topic.

I found this answer here

Be sure you run the tool with admin-rights.

I think the question is incomplete. if you meant that you wish to get the type information of some typeclass then below:

If you wish to print as you have specified then:

scala>  def manOf[T: Manifest](t: T): Manifest[T] = manifest[T]
manOf: [T](t: T)(implicit evidence$1: Manifest[T])Manifest[T]

scala> val x = List(1,2,3)
x: List[Int] = List(1, 2, 3)

scala> println(manOf(x))
scala.collection.immutable.List[Int]

If you are in repl mode then

scala> :type List(1,2,3)
List[Int]

Or if you just wish to know what the class type then as @monkjack explains "string".getClass might solve the purpose

@Logan said it perfectly. but i would like to add an alternative here,

if you want to view logs from just your application then you can make a custom method that keeps saving the log to a file in documents directory & then you can view that log file from your application.

There is one good advantage for developers of the app after the app has been released & users are downloading it. Because your app will be able to send logs & crash reports to the developers (of course with the permissions of the device user !!!) & it'll be the way to improve your application.

Let me know (To other SO users), if there is another way of doing the same thing. (Like default Apple feature or something)

Let me know if it helps or you want some more idea.

Reinstall everything??? no way! just add the path to SDK tools and platform tools in your classpath from Environment Variables. Then restart Eclipse.

other way go to Devices -> Reset adb, or simply open the task manager and kill the adb.exe process.

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

position: absolute will remove it from the layout flow and should solve your problem - the element will remain in the DOM but won't affect others.

In my case, I have setup like

AWS ELB >> ECS(nginx) >> ECS(php-fpm).

I had configured the wrong AWS security group for ECS(php-fpm) service, so Nginx wasn't able to reach out to php-fpm task container. That's why i was getting errors in nginx task log

499 0 - elb-healthchecker/2.0

Health check was configured as to check php-fpm service and confirm it's up and give back a response.

You should write something like this.

<a href="#" style="text-decoration:none;">BOOK NOW</a>

Using "setInterval" & "clearInterval" fixes the problem:

function drawMarkers(map, markers) {
    var _this = this,
        geocoder = new google.maps.Geocoder(),
        geocode_filetrs;

    _this.key = 0;

    _this.interval = setInterval(function() {
        _this.markerData = markers[_this.key];

        geocoder.geocode({ address: _this.markerData.address }, yourCallback(_this.markerData));

        _this.key++;

        if ( ! markers[_this.key]) {
            clearInterval(_this.interval);
        }

    }, 300);
}

Splat Method with Calculations

If you choose splat method, beware calculations that are made using other parameters. In practice, sometimes I have to set variables first then create the hash table. Also, the format doesn't require single quotes around the key value or the semi-colon (as mentioned above).

Example of a call to a function that creates an Excel spreadsheet

$title = "Cut-off File Processing on $start_date_long_str"
$title_row = 1
$header_row = 2
$data_row_start = 3
$data_row_end = $($data_row_start + $($file_info_array.Count) - 1)

# use parameter hash table to make code more readable
$params = @{
    title = $title
    title_row = $title_row
    header_row = $header_row
    data_row_start = $data_row_start
    data_row_end = $data_row_end
}
$xl_wksht = Create-Excel-Spreadsheet @params

Note: The file array contains information that will affect how the spreadsheet is populated.

Learn from another guy:

<a onclick="window.open(this.href,'_blank');return false;" href="http://www.foracure.org.au">Some Other Site</a>

It makes sense to me.

first , you dont need to use a local assigment for your job, just check the above answer

second, its simple to use locals() and globals() to got the variables table and then change the value

check this sample code:

print [locals().__setitem__('x', 'Hillo :]'), x][-1]

if you need to change the add a global variable to your environ, try to replace locals() with globals()

python's list comp is cool but most of the triditional project dont accept this(like flask :[)

hope it could help

This error happened on my server when I imported a view with an invalid definer.

Removing the faulty view fixed the error.

The error message didn't say anything about the view in question, but was "complaining" about one of the tables, that was used in the view.

Data in jQuery ajax() function accepts anonymous objects as its input, see documentation. So example of what you're looking for is:

dataString = {key: 'val', key2: 'val2'};
$.ajax({
        type: "POST",
        url: "script.php",
        data: dataString, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

You may also write POST/GET query on your own, like key=val&key2=val2, but you'd have to handle escaping yourself which is impractical.

Connect with SSH and follow these instructions to install Node on a shared hosting

In short you first install NVM, then you install the Node version of your choice with NVM.

wget -qO- https://cdn.rawgit.com/creationix/nvm/master/install.sh | bash

Your restart your shell (close and reopen your sessions). Then you

nvm install stable

to install the latest stable version for example. You can install any version of your choice. Check node --version for the node version you are currently using and nvm list to see what you've installed.

In bonus you can switch version very easily (nvm use <version>)

There's no need of PHP or whichever tricky workaround if you have SSH.

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

SELECT (sub)queries return result sets. So you need to use IN, not = in your WHERE clause.

Additionally, as shown in this answer you cannot modify the same table from a subquery within the same query. However, you can either SELECT then DELETE in separate queries, or nest another subquery and alias the inner subquery result (looks rather hacky, though):

DELETE FROM posts WHERE id IN (
    SELECT * FROM (
        SELECT id FROM posts GROUP BY id HAVING ( COUNT(id) > 1 )
    ) AS p
)

Or use joins as suggested by Mchl.

The main image manager in PIL is PIL's Image module.

from PIL import Image
import math

foo = Image.open("path\\to\\image.jpg")
x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)
foo = foo.resize((x2,y2),Image.ANTIALIAS)
foo.save("path\\to\\save\\image_scaled.jpg",quality=95)

You can add optimize=True to the arguments of you want to decrease the size even more, but optimize only works for JPEG's and PNG's. For other image extensions, you could decrease the quality of the new saved image. You could change the size of the new image by just deleting a bit of code and defining the image size and you can only figure out how to do this if you look at the code carefully. I defined this size:

x, y = foo.size
x2, y2 = math.floor(x-50), math.floor(y-20)

just to show you what is (almost) normally done with horizontal images. For vertical images you might do:

x, y = foo.size
x2, y2 = math.floor(x-20), math.floor(y-50)

. Remember, you can still delete that bit of code and define a new size.

You can use the @RequestHeader annotation with HttpHeaders method parameter to gain access to all request headers:

@RequestMapping(value = "/restURL")
public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers) {
    // Use headers to get the information about all the request headers
    long contentLength = headers.getContentLength();
    // ...
    StreamSource source = new StreamSource(new StringReader(body));
    YourObject obj = (YourObject) jaxb2Mashaller.unmarshal(source);
    // ...
}

Dim have had different meanings attributed to it.

I've found references about Dim meaning "Declare In Memory", the more relevant reference is a document on Dim Statement published Oracle as part of the Siebel VB Language Reference. Of course, you may argue that if you do not declare the variables in memory where do you do it? Maybe "Declare in Module" is a good alternative considering how Dim is used.

In my opinion, "Declare In Memory" is actually a mnemonic, created to make easier to learn how to use Dim. I see "Declare in Memory" as a better meaning as it describes what it does in current versions of the language, but it is not the proper meaning.

In fact, at the origins of Basic Dim was only used to declare arrays. For regular variables no keyword was used, instead their type was inferred from their name. For instance, if the name of the variable ends with $ then it is a string (this is something that you could see even in method names up to VB6, for example Mid$). And so, you used Dim only to give dimension to the arrays (notice that ReDim resizes arrays).

Really, Does It Matter? I mean, it is a keyword it has its meaning inside an artificial language. It doesn't have to be a word in English or any other natural language. So it could just mean whatever you want, all that matters is that it works.

Anyhow, that is not completely true. As BASIC is part of our culture, and understanding why it came to be as it is - I hope - will help improve our vision of the world.

I sit in from of my computer with a desire to help preserve this little piece of our culture that seems lost, replaced by our guessing of what it was. And so, I have dug MSDN both current and the old CDs from the 1998 version. I have also searched the documention for the old QBasic [Had to use DOSBox] and managed to get some Darthmouth manual, all to find how they talk about Dim. For my disappointment, they don't say what does Dim stand for, and only say how it is used.

But before my hope was dim, I managed to find this BBC Microcomputer System Used Guide (that claims to be from 1984, and I don't want to doubt it). The BBC Microcomputer used a variant of BASIC called BBC BASIC and it is described in the document. Even though, it doesn't say what does Dim stand for, it says (on page 104):

... you can dimension N$ to have as many entries as you want. For example, DIM N$(1000) would create a string array with space for 1000 different names.

As I said, it doesn't say that Dim stands for dimension, but serves as proof to show that associating Dim with Dimension was a common thing at the time of writing that document.

Now, I got a rewarding surprise later on (at page 208), the title for the section that describes the DIM keyword (note: that is not listed in the contents) says:

DIM dimension of an array

So, I didn't get the quote "Dim stands for..." but I guess it is clear that any decent human being that is able to read those document will consider that Dim means dimension.

With renewed hope, I decided to search about how Dim was chosen. Again, I didn't find an account on the subject, still I was able to find a definitive quote:

Before you can use an array, you must define it in a DIM (dimension) statement.

You can find this as part of the True BASIC Online User's Guides at the web page of True BASIC inc, a company founded by Thomas Eugene Kurtz, co-author of BASIC.

So, In reallity, Dim is a shorthand for DIMENSION, and yes. That existed in FORTRAN before, so it is likely that it was picked by influence of FORTRAN as Patrick McDonald said in his answer.

Dim sum as string = "this is not a chinese meal" REM example usage in VB.NET ;)

Bit late on this thread. angular.equals does deep check, however does anyone know that why its behave differently if one of the member contain "$" in prefix ?

You can try this Demo with following input

var obj3 = {}
obj3.a=  "b";
obj3.b={};
obj3.b.$c =true;

var obj4 = {}
obj4.a=  "b";
obj4.b={};
obj4.b.$c =true;

angular.equals(obj3,obj4);

The TableModel behind the JTable handles all of the data behind the table. In order to add and remove rows from a table, you need to use a DefaultTableModel

To create the table with this model:

JTable table = new JTable(new DefaultTableModel(new Object[]{"Column1", "Column2"}));

To add a row:

DefaultTableModel model = (DefaultTableModel) table.getModel();
model.addRow(new Object[]{"Column 1", "Column 2", "Column 3"});

You can also remove rows with this method.

Full details on the DefaultTableModel can be found here

The views are probably created using the WITH SCHEMABINDING option and this means they are explicitly wired up to prevent such changes. Looks like the schemabinding worked and prevented you from breaking those views, lucky day, heh? Contact your database administrator and ask him to do the change, after it asserts the impact on the database.

From MSDN:

SCHEMABINDING

Binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition. The view definition itself must first be modified or dropped to remove dependencies on the table that is to be modified.

I would use CSS to prevent the :hover event from changing the appearance of the link.

a{
  font:normal 12px/15px arial,verdana,sans-serif;
  color:#000;
  text-decoration:none;
}

This simple CSS means that the links will always be black and not underlined. I cannot tell from the question whether the change in the appearance is the only thing you want to control.

Invoke the windows port of md5sum.exe. It's about two times as fast as the .NET implementation (at least on my machine using a 1.2 GB file)

public static string Md5SumByProcess(string file) {
    var p = new Process ();

The concept of leading zero is meaningless for an int, which is what you have. It is only meaningful, when printed out or otherwise rendered as a string.

Console.WriteLine("{0:0000000}", FileRecordCount);

Forgot to end the double quotes!

open CMD and run this commands

NET STOP MSSQLSERVER
NET START MSSQLSERVER

this will restart the SQL Server instance. try to run again after your delete command

I have this command in a batch script and run it from time to time if I'm encountering problems like this. A normal PC restart will not be the same so restarting the instance is the most effective way if you are encountering some issues with your sql server.

Invoking an empty time.Time struct literal will return Go's zero date. Thus, for the following print statement:

fmt.Println(time.Time{})

The output is:

0001-01-01 00:00:00 +0000 UTC

For the sake of completeness, the official documentation explicitly states:

The zero value of type Time is January 1, year 1, 00:00:00.000000000 UTC.

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

Yes, you should set ServerName:

http://wiki.apache.org/httpd/CouldNotDetermineServerName

http://httpd.apache.org/docs/current/mod/core.html#servername

You can find information on the layouts used by the various httpd distributions here:

http://wiki.apache.org/httpd/DistrosDefaultLayout

In your case the file to edit is /etc/httpd/conf/httpd.conf

$DB_TYPE = 'mysql'; //Type of database<br>
$DB_HOST = 'localhost'; //Host name<br>
$DB_USER = 'root'; //Host Username<br>
$DB_PASS = ''; //Host Password<br>
$DB_NAME = 'database_name'; //Database name<br><br>

$dbh = new PDO("$DB_TYPE:host=$DB_HOST; dbname=$DB_NAME;", $DB_USER, $DB_PASS); // PDO Connection

This worked for me.

Yes, Its possible in SQL, but we can't set more than one primary keys in MsAccess. Then, I don't know about the other databases.

Goodluck

I am an old hand at programming and came back recently to my old passion and am struggling to fit in this Object oriented, event driven bright new world and while i see the advantages of the non sequential behavior of Javascript there are time where it really get in the way of simplicity and reusability. A simple example I have worked on was to take a photo (Mobile phone programmed in javascript, HTML, phonegap, ...), resize it and upload it on a web site. The ideal sequence is :

1. Take a photo
2. Load the photo in an img element
3. Resize the picture (Using Pixastic)
4. Upload it to a web site
5. Inform the user on success failure

All this would be a very simple sequential program if we would have each step returning control to the next one when it is finished, but in reality :

1. Take a photo is async, so the program attempt to load it in the img element before it exist
2. Load the photo is async so the resize picture start before the img is fully loaded
3. Resize is async so Upload to the web site start before the Picture is completely resized
4. Upload to the web site is asyn so the program continue before the photo is completely uploaded.

And btw 4 of the 5 steps involve callback functions.

My solution thus is to nest each step in the previous one and use .onload and other similar stratagems, It look something like this :

takeAPhoto(takeaphotocallback(photo) {
  photo.onload = function () {
    resizePhoto(photo, resizePhotoCallback(photo) {
      uploadPhoto(photo, uploadPhotoCallback(status) {
        informUserOnOutcome();
      });
    }); 
  };
  loadPhoto(photo);
});

(I hope I did not make too many mistakes bringing the code to it's essential the real thing is just too distracting)

This is I believe a perfect example where async is no good and sync is good, because contrary to Ui event handling we must have each step finish before the next is executed, but the code is a Russian doll construction, it is confusing and unreadable, the code reusability is difficult to achieve because of all the nesting it is simply difficult to bring to the inner function all the parameters needed without passing them to each container in turn or using evil global variables, and I would have loved that the result of all this code would give me a return code, but the first container will be finished well before the return code will be available.

Now to go back to Tom initial question, what would be the smart, easy to read, easy to reuse solution to what would have been a very simple program 15 years ago using let say C and a dumb electronic board ?

The requirement is in fact so simple that I have the impression that I must be missing a fundamental understanding of Javsascript and modern programming, Surely technology is meant to fuel productivity right ?.

Thanks for your patience

I followed below steps for resolution for this issue in Windows 10:

1. First make sure you have installed Angular CLI . You can use below to install same.

npm install -g @angular/cli@latest

2. Make sure that AppData is visible and navigate to path below.

C:\Users\rkota\AppData\Roaming\npm

Same path can be found by running below too:

npm config get prefix

3. Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
4. Close command prompt and now try to run below:

ng --version

you will be able to see CLI version.

I'm assuming from your question that you don't want directories names, just files.

Directory Structure Example

animals
+-- all.jpg
+-- mammals
¦   +-- cat.jpg
¦   +-- dog.jpg
+-- insects
    +-- bee.jpg

Walk function

Credits go to Justin Maier in this gist

If you want just an array of the files paths use return_object: false:

const fs = require('fs').promises;
const path = require('path');

async function walk(dir) {
    let files = await fs.readdir(dir);
    files = await Promise.all(files.map(async file => {
        const filePath = path.join(dir, file);
        const stats = await fs.stat(filePath);
        if (stats.isDirectory()) return walk(filePath);
        else if(stats.isFile()) return filePath;
    }));

    return files.reduce((all, folderContents) => all.concat(folderContents), []);
}

Usage

async function main() {
   console.log(await walk('animals'))
}

Output

[
  "/animals/all.jpg",
  "/animals/mammals/cat.jpg",
  "/animals/mammals/dog.jpg",
  "/animals/insects/bee.jpg"
];

Now you must have API key. You can generate that in google developer console. Here is LINK to the explanation.

Lexical (AKA static) scoping refers to determining a variable's scope based solely on its position within the textual corpus of code. A variable always refers to its top-level environment. It's good to understand it in relation to dynamic scope.

It looks like you just want:

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
    ? (DateTime?) null
    : DateTime.Parse(dateTimeEnd);

Note that this will throw an exception if dateTimeEnd isn't a valid date.

An alternative would be:

DateTime validValue;
eventCustom.DateTimeEnd = DateTime.TryParse(dateTimeEnd, out validValue)
    ? validValue
    : (DateTime?) null;

That will now set the result to null if dateTimeEnd isn't valid. Note that TryParse handles null as an input with no problems.

You can use following regular expression construct

Punctuation: One of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~

inputString.replaceAll("\\p{Punct}", "");

Please use this at class level for the bean:

@JsonIgnoreProperties(value={"hibernateLazyInitializer","handler","fieldHandler"})

if this structure is to be used by some other file func.c how to do it?

When a type is used in a file (i.e. func.c file), it must be visible. The very worst way to do it is copy paste it in each source file needed it.

The right way is putting it in an header file, and include this header file whenever needed.

shall we open a new header file and declare the structure there and include that header in the func.c?

This is the solution I like more, because it makes the code highly modular. I would code your struct as:

#ifndef SOME_HEADER_GUARD_WITH_UNIQUE_NAME
#define SOME_HEADER_GUARD_WITH_UNIQUE_NAME

struct a
{ 
    int i;
    struct b
    {
        int j;
    }
};

#endif

I would put functions using this structure in the same header (the function that are "semantically" part of its "interface").

And usually, I could name the file after the structure name, and use that name again to choose the header guards defines.

If you need to declare a function using a pointer to the struct, you won't need the full struct definition. A simple forward declaration like:

struct a ;

Will be enough, and it decreases coupling.

or can we define the total structure in header file and include that in both source.c and func.c?

This is another way, easier somewhat, but less modular: Some code needing only your structure to work would still have to include all types.

In C++, this could lead to interesting complication, but this is out of topic (no C++ tag), so I won't elaborate.

then how to declare that structure as extern in both the files. ?

I fail to see the point, perhaps, but Greg Hewgill has a very good answer in his post How to declare a structure in a header that is to be used by multiple files in c?.

shall we typedef it then how?

• If you are using C++, don't.
• If you are using C, you should.

The reason being that C struct managing can be a pain: You have to declare the struct keyword everywhere it is used:

struct MyStruct ; /* Forward declaration */

struct MyStruct
{
   /* etc. */
} ;

void doSomething(struct MyStruct * p) /* parameter */
{
   struct MyStruct a ; /* variable */
   /* etc */
}

While a typedef will enable you to write it without the struct keyword.

struct MyStructTag ; /* Forward declaration */

typedef struct MyStructTag
{
   /* etc. */
} MyStruct ;

void doSomething(MyStruct * p) /* parameter */
{
   MyStruct a ; /* variable */
   /* etc */
}

It is important you still keep a name for the struct. Writing:

typedef struct
{
   /* etc. */
} MyStruct ;

will just create an anonymous struct with a typedef-ed name, and you won't be able to forward-declare it. So keep to the following format:

typedef struct MyStructTag
{
   /* etc. */
} MyStruct ;

Thus, you'll be able to use MyStruct everywhere you want to avoid adding the struct keyword, and still use MyStructTag when a typedef won't work (i.e. forward declaration)

Edit:

Corrected wrong assumption about C99 struct declaration, as rightfully remarked by Jonathan Leffler.

Edit 2018-06-01:

Craig Barnes reminds us in his comment that you don't need to keep separate names for the struct "tag" name and its "typedef" name, like I did above for the sake of clarity.

Indeed, the code above could well be written as:

typedef struct MyStruct
{
   /* etc. */
} MyStruct ;

IIRC, this is actually what C++ does with its simpler struct declaration, behind the scenes, to keep it compatible with C:

// C++ explicit declaration by the user
struct MyStruct
{
   /* etc. */
} ;
// C++ standard then implicitly adds the following line
typedef MyStruct MyStruct;

Back to C, I've seen both usages (separate names and same names), and none has drawbacks I know of, so using the same name makes reading simpler if you don't use C separate "namespaces" for structs and other symbols.

None of the above was suitable, without calling session_start() in all php files that depend on $Session variables they will not be included. The Notice is so annoying and quickly fill up the Error_log. The only solution that I can find that works is this....

    error_reporting(E_ALL ^ E_NOTICE);
    session_start();

A Bad fix , but it works.

I'm using Eclipse Europa, which also has the Favorite preference section:

Window > Preferences > Java > Editor > Content Assist > Favorites

In mine, I have the following entries (when adding, use "New Type" and omit the .*):

org.hamcrest.Matchers.*
org.hamcrest.CoreMatchers.*
org.junit.*
org.junit.Assert.*
org.junit.Assume.*
org.junit.matchers.JUnitMatchers.*

All but the third of those are static imports. By having those as favorites, if I type "assertT" and hit Ctrl+Space, Eclipse offers up assertThat as a suggestion, and if I pick it, it will add the proper static import to the file.

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

I had a slightly different situation, when both JDK and JRE 1.8.0_112 were present on my system.

I imported the new CA certificates into [JDK_FOLDER]\jre\lib\security\cacerts using the already known command:

keytool -import -trustcacerts -keystore cacerts -alias <new_ca_alias> -file <path_to_ca_cert_file>

Still, I kept getting the same PKIX path building failed error.

I added debug information to the java CLI, by using java -Djavax.net.debug=all ... > debug.log. In the debug.log file, the line that begins with trustStore is: actually pointed to the cacerts store found in [JRE_FOLDER]\lib\security\cacerts.

In my case the solution was to copy the cacerts file used by JDK (which had the new CAs added) over the one used by the JRE and that fixed the issue.

The key is "I installed the postgres.app for mac." This application sets up the local PostgreSQL installation with a database superuser whose role name is the same as your login (short) name.

When Postgres.app first starts up, it creates the $USER database, which is the default database for psql when none is specified. The default user is $USER, with no password.

Some scripts (e.g., a database backup created with pgdump on a Linux systsem) and tutorials will assume the superuser has the traditional role name of postgres.

You can make your local install look a bit more traditional and avoid these problems by doing a one time:

/Applications/Postgres.app/Contents/Versions/9.*/bin/createuser -s postgres

which will make those FATAL: role "postgres" does not exist go away.

Unique key is actually an index. http://codeghar.wordpress.com/2008/03/28/drop-unique-constraint-in-mysql/

The following works for me in Node.js 12.x:

npm i node-fetch;

to initialize the Dropbox instance:

var Dropbox = require("dropbox").Dropbox;
var dbx = new Dropbox({
   accessToken: <your access token>,
   fetch: require("node-fetch")    
});

to e.g. upload a content (an asynchronous method used in this case):

await dbx.filesUpload({
  contents: <your content>,
  path: <file path>
});

Setting the id attribute when appending the svg element can also let d3 select so remove() later on this element by id :

var svg = d3.select("theParentElement").append("svg")
.attr("id","the_SVG_ID")
.attr("width",...

...

d3.select("#the_SVG_ID").remove();

I would like to add the speed issue - the current fastest way, on google chrome is the second one.

But pay attention, these things tend to change a lot with updates. Also the run time will differ between different browsers.

For example - the 2nd option that i mentioned, runs at 2 million [ops/second] on chrome, but if you'd try it on mozilla dev. you'd get a surprisingly higher rate of 23 million.

Anyway, I'd suggest you check it out, every once in a while, on different browsers (and machines), using site as such

Instead of the -f of make you might want to use the -C <path> option. This first changes the to the path '<path>', and then calles make there.

Example:

clean:
  rm -f ./*~ ./gmon.out ./core $(SRC_DIR)/*~ $(OBJ_DIR)/*.o
  rm -f ../svn-commit.tmp~
  rm -f $(BIN_DIR)/$(PROJECT)
  $(MAKE) -C gtest-1.4.0/make clean

I think this is easy way to drop the index.

set FOREIGN_KEY_CHECKS=0; //disable checks

ALTER TABLE mytable DROP INDEX AID;

set FOREIGN_KEY_CHECKS=1; //enable checks

Try moving the --exclude to before the include.

tar -pczf MyBackup.tar.gz --exclude "/home/user/public_html/tmp/" /home/user/public_html/ 

The problem is the padding of the font on the textview. Just add to your textview:

android:includeFontPadding="false"

Simplest way is to use dimensions in % or em. Just change the base font size everything will change.

@media (max-width: @screen-xs) {
    body{font-size: 10px;}
}

@media (max-width: @screen-sm) {
    body{font-size: 14px;}
}


h5{
    font-size: 1.4rem;
}

You could use viewport units (vh,vw...) but they dont work on Android < 4.4

Try this. It avoids mutating a thing you're iterating across, which is generally a code smell.

for i in xrange(0, 100, 3):
    print i

See xrange.

There’s a new HTML5 approach to this, the formaction attribute:

<button type="submit" formaction="/action_one">First action</button>
<button type="submit" formaction="/action_two">Second action</button>

Apparently this does not work in IE9 and earlier, but for other browsers you should be fine (see: w3schools.com HTML <button> formaction Attribute).

Personally, I generally use Javascript to submit forms remotely (for faster perceived feedback) with this approach as backup. Between the two, the only people not covered are IE<9 with Javascript disabled.

Of course, this may be inappropriate if you’re basically taking the same action server-side regardless of which button was pushed, but often if there are two user-side actions available then they will map to two server-side actions as well.

Edit: As noted by Pascal_dher in the comments, this attribute is also available on the <input> tag as well.

It is defined as:

typedef unsigned long       DWORD;

However, according to the MSDN:

On 32-bit platforms, long is synonymous with int.

Therefore, DWORD is 32bit on a 32bit operating system. There is a separate define for a 64bit DWORD:

typdef unsigned _int64 DWORD64;

Hope that helps.

It's the ternary operator ?

string newString = i == 1 ? "i is one" : "i is not one";

I found your question looking for a solution to the same problem; and what other answers fail to point is a way to use a variable to change the name of the table for every execution of your procedure in a permanent form, not temporary.

So far what I do is concatenate the entire SQL code with the variables to use. Like this:

declare @table_name as varchar(30)
select @table_name = CONVERT(varchar(30), getdate(), 112)
set @table_name = 'DAILY_SNAPSHOT_' + @table_name

EXEC('
        SELECT var1, var2, var3
        INTO '+@table_name+'
        FROM my_view
        WHERE string = ''Strings must use double apostrophe''
    ');

I hope it helps, but it could be cumbersome if the code is too large, so if you've found a better way, please share!

If you want to do this in VBA, then this is a shorter method:

Sub FillBlanksWithNull()

'This macro will fill all "blank" cells with the text "Null"

'When no range is selected, it starts at A1 until the last used row/column

'When a range is selected prior, only the blank cell in the range will be used.

On Error GoTo ErrHandler:

Selection.SpecialCells(xlCellTypeBlanks).FormulaR1C1 = "Null"

Exit Sub

ErrHandler:

MsgBox "No blank cells found", vbDefaultButton1, Error

Resume Next

End Sub
