What you're looking for is

[ConditionalAttribute("DEBUG")]

attribute.

If you for instance write a method like :

[ConditionalAttribute("DEBUG")]
public static void MyLovelyDebugInfoMethod(string message)
{
    Console.WriteLine("This message was brought to you by your debugger : ");
    Console.WriteLine(message);
}

any call you make to this method inside your own code will only be executed in debug mode. If you build your project in release mode, even call to the "MyLovelyDebugInfoMethod" will be ignored and dumped out of your binary.

Oh and one more thing if you're trying to determine whether or not your code is currently being debugged at the execution moment, it is also possible to check if the current process is hooked by a JIT. But this is all together another case. Post a comment if this is what you2re trying to do.

At first I would use http://ruby.railstutorial.org/.

And database.yml is place where you put setup for database your application use - username, password, host - for each database. With new application you dont need to change anything - simply use default sqlite setup.

I had similar problem (in bash terminal command was working correctly but zsh showed command not found error)

Solution:

just paste whatever you were earlier pasting in ~/.bashrc to:

~/.zshrc

If you don't want any separator after the last cell, then you need a close to zero but non-zero height for your footer.

In your UITableViewDelegate:

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return .leastNormalMagnitude
}

It works fine for me, but it's a little tricky :)

• First open the PuTTY configuration.
• Select the session (right part of the window, Saved Sessions)
• Click Load (now you have loaded Host Name, Port and Connection type)
• Then click Logging (under Session on the left)
• Change whatever settings you want
• Go back to Session window and click the Save button

Now you have settings for this session set (every time you load session it will be logged).

One of the most straightforward ways to do it is

git for-each-ref --format='%(refname:short)' refs/heads/

This works perfectly for scripts as well.

See .offset() here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset() and .position() confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop() and .scrollLeft() values to account for the scrolled position.

Here's an excerpt from the doc:

The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.

To combine these:

var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft(); 

You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/

Add this code to the beginning:

    Application.ScreenUpdating = False
     With ThisWorkbook
      Dim ws As Worksheet
       For Each ws In Worksheets: ws.Visible = True: Next ws
     End With

Add this code to the end:

    With ThisWorkbook
     Dim ws As Worksheet
      For Each ws In Worksheets: ws.Visible = False: Next ws
    End With
     Application.ScreenUpdating = True

Adjust Code at the end if you want more than the first sheet to be active and visible. Such as the following:

     Dim ws As Worksheet
      For Each ws In Worksheets
       If ws.Name = "_DataRecords" Then

         Else: ws.Visible = False
       End If
      Next ws

To ensure the new sheet is the one renamed, adjust your code similar to the following:

     Sheets(Me.cmbxSheetCopy.value).Copy After:=Sheets(Sheets.Count)
     Sheets(Me.cmbxSheetCopy.value & " (2)").Select
     Sheets(Me.cmbxSheetCopy.value & " (2)").Name = txtbxNewSheetName.value

This code is from my user form that allows me to copy a particular sheet (chosen from a dropdown box) with the formatting and formula's that I want to a new sheet and then rename new sheet with the user Input. Note that every time a sheet is copied it is automatically given the old sheet name with the designation of " (2)". Example "OldSheet" becomes "OldSheet (2)" after the copy and before the renaming. So you must select the Copied sheet with the programs naming before renaming.

git diff branch_1..branch_2

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

git diff branch_1...branch_2

I am working on a ten years old project at work. So 5.6 is my default. There are also older small projects which only works with 5.2 and I also want to work on new versions for my personal projects with 7.3.8

Here is what I did to add 5.2 and 7.3.8 on default 5.6 version.

1 - Downloaded php TS versions ;

• v7.3.8(latest) : https://windows.php.net/download/

• v5.2 : https://www.apachelounge.com/viewtopic.php?t=7349

2 - Extracted to c:\xampp\php738 and c:\xampp\php52 folder in order

3 - Added these lines to the bottom of httpd-xampp.conf (or httpd.conf) ;

*** IMPORTANT NOTICE : You should NOT use script alias name as your target folder name, they must be different. (for instance /php7x is ok , /php7 is not)

PHP 7.3.8 for folder D:\www\php7

ScriptAlias /php7x "C:/xampp/php738"
Action application/x-httpd-php7-cgi /php7x/php-cgi.exe
<Directory "C:/xampp/php738">
    AllowOverride None
    Options None
    Require all denied
    <Files "php-cgi.exe">
        Require all granted
    </Files>
</Directory>

<Directory "D:\www\php7">
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php7-cgi
    </FilesMatch>
</Directory>

PHP 5.2 for folder D:\www\php52

ScriptAlias /phpold "C:/xampp/php52"
Action application/x-httpd-phpold-cgi /phpold/php-cgi.exe
<Directory "C:/xampp/php52">
    AllowOverride None
    Options None
    Require all denied
    <Files "php-cgi.exe">
        Require all granted
    </Files>
</Directory>

<Directory "D:\www\php52">
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-phpold-cgi
    </FilesMatch>
</Directory>

Some helpful notes :

• If you have troubles with php5.x while using composer switch terminal to 7.3.8
• If you want to make php 7.3.8 your default command line php interpreter on windows just change your windows environment path for php to the 7.3.8 folder path.
• Don't forget to edit your relevant php.ini confs as you need in each version folder.

And as a last bonus note , if you need to set a virtual host with any of versions you can use similar approach. A sample laravel vhost conf for php 7.3.8;

<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "D:\www\vhosts\laravel.local\public"
ServerName  laravel.local
<FilesMatch "\.php$">
 SetHandler application/x-httpd-php7-cgi # escape for default php version
#SetHandler application/x-httpd-phpold-cgi # unescape for php 5.2
</FilesMatch>

ErrorLog "logs/laravel.local.log"
CustomLog "logs/laravel.local.log" combined

Thanks to @Munim Munna for detailed answer, I wanted to share a solid sample with the important notice above.

Here is a snippet for not only closing modals without page refresh but when pressing enter it submits modal and closes without refresh

I have it set up on my site where I can have multiple modals and some modals process data on submit and some don't. What I do is create a unique ID for each modal that does processing. For example in my webpage:

HTML (modal footer):

 <div class="modal-footer form-footer"><br>
              <span class="caption">
                <button id="PreLoadOrders" class="btn btn-md green btn-right" type="button" disabled>Add to Cart&nbsp; <i class="fa fa-shopping-cart"></i></button>     
                <button id="ClrHist" class="btn btn-md red btn-right" data-dismiss="modal" data-original-title="" title="Return to Scan Order Entry" type="cancel">Cancel&nbsp; <i class="fa fa-close"></i></a>
              </span>
      </div>

jQUERY:

$(document).ready(function(){
// Allow enter key to trigger preloadorders form
    $(document).keypress(function(e) {       
      if(e.which == 13) {   
          e.preventDefault();   
                if($(".trigger").is(".ok")) 
                   $("#PreLoadOrders").trigger("click");
                else
                    return;
      }
    });
});

As you can see this submit performs processing which is why I have this jQuery for this modal. Now let's say I have another modal within this webpage but no processing is performed and since one modal is open at a time I put another $(document).ready() in a global php/js script that all pages get and I give the modal's close button a class called: ".modal-close":

HTML:

<div class="modal-footer caption">
                <button type="submit" class="modal-close btn default" data-dismiss="modal" aria-hidden="true">Close</button>
            </div>

jQuery (include global.inc):

  $(document).ready(function(){
         // Allow enter key to trigger a particular button anywhere on page
        $(document).keypress(function(e) {
                if(e.which == 13) {
                   if($(".modal").is(":visible")){   
                        $(".modal:visible").find(".modal-close").trigger('click');
                    }
                }
         });
    });

You need to install the Visual C++ libraries: http://www.microsoft.com/en-us/download/details.aspx?id=30679

As mentioned by Stuart McLaughlin, make sure you get the x86 version even if you use a 64-bits OS because PHP needs some 32-bit libraries.

If you only want to remove the boundary quotes:

function stripquotes(a) {
    if (a.charAt(0) === '"' && a.charAt(a.length-1) === '"') {
        return a.substr(1, a.length-2);
    }
    return a;
}

This approach won't touch the string if it doesn't look like "text in quotes".

You can use the redirect() function. Like this

class ControllerA extends CI_Controller{
    public function MethodA(){
       redirect("ControllerB/MethodB");
    }
}

To get the value from a textarea with an id you just have to do

Edited

$("#area1").val();

If you are having more than one element with the same id in the document then the HTML is invalid.

the $("body").append(r) statement should be within the test function, also there was misplaced " in the test method

function test() {
    var r=$('<input/>').attr({
        type: "button",
        id: "field",
        value: 'new'
    });
    $("body").append(r);    
}

Demo: Fiddle

Update
In that case try a more jQuery-ish solution

<!DOCTYPE html>
<html>
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script type="text/javascript">
          jQuery(function($){
              $('#mybutton').one('click', function(){
                  var r=$('<input/>').attr({
                      type: "button",
                      id: "field",
                      value: 'new'
                  });
                  $("body").append(r);   
              })
          })
        </script>
    </head>
    <body>
        <button id="mybutton">Insert after</button> 
    </body>
</html>

I've stored a script in my gist to download an extension from the marketplace using a PowerShell script. Feel free to comment of share it.

In Sybase SQL Anywhere:

SELECT TOP 1 START AT n * from table ORDER BY whatever

Don't forget the ORDER BY or it's meaningless.

I never had any luck with that approach. I always do this (hope this helps):

var obj = {};

obj.first_name = $("#namec").val();
obj.last_name = $("#surnamec").val();
obj.email = $("#emailc").val();
obj.mobile = $("#numberc").val();
obj.password = $("#passwordc").val();

Then in your ajax:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify(obj),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
    });

InputStream in = getResources().openRawResource(resourceName);

This will work correctly. Before that you have to create the xml file / text file in raw resource. Then it will be accessible.

Edit
Some times com.andriod.R will be imported if there is any error in layout file or image names. So You have to import package correctly, then only the raw file will be accessible.

As of 2015, you can make it and center the text with as few as 15 lines of CSS (Fiddle):

body {_x000D_
  background-color: #fff;_x000D_
}_x000D_
#circle {_x000D_
  position: relative;_x000D_
  background-color: #09f;_x000D_
  margin: 20px auto;_x000D_
  width: 400px;_x000D_
  height: 400px;_x000D_
  border-radius: 200px;_x000D_
}_x000D_
#text {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  left: 50%;_x000D_
  transform: translate(-50%, -50%);_x000D_
  color: #fff;_x000D_
}

<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
_x000D_
<head>_x000D_
  <meta charset="UTF-8">_x000D_
  <title>circle with text</title>_x000D_
_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
  <div id="circle">_x000D_
    <div id="text">Text in the circle</div>_x000D_
  </div>_x000D_
</body>_x000D_
_x000D_
</html>

Without any -webkit-s, this works on IE11, Firefox, Chrome and Opera, and it is valid HTML5 (experimental) and CSS3.

Same on MS Edge (2020).

A simple solution would be to just write

this.date = new Date().toLocaleDateString();

date .toLocaleDateString() time .toLocaleTimeString() both .toLocaleString()

Hope this helps.

I have tried all the above solutions. But it was not working in any way.

Finally, I just uninstalled XAMPP and installed it again. Then it worked for me.

Now I am able to run the server on any port (including 80).

There are two ways. 1. if you want to implement app.module.ts file then:

import { Routes, RouterModule } from '@angular/router';_x000D_
_x000D_
const appRoutes: Routes = [_x000D_
  { path: '', component: HomeComponent },_x000D_
  { path: 'user', component: UserComponent },_x000D_
  { path: 'server', component: ServerComponent }_x000D_
];_x000D_
_x000D_
@NgModule({_x000D_
  imports: [_x000D_
    RouterModule.forRoot(appRoutes)_x000D_
  ]_x000D_
})_x000D_
export class AppModule { }

2. if you want to implement app-routing.module.ts (Separated Routing Module) file then:

//app-routing.module.ts_x000D_
import { NgModule } from '@angular/core';_x000D_
import { Routes, RouterModule } from '@angular/router';_x000D_
_x000D_
const appRoutes: Routes = [_x000D_
  { path: '', component: HomeComponent },_x000D_
  { path: 'users', component: UsersComponent },_x000D_
  { path: 'servers', component: ServersComponent }_x000D_
];_x000D_
_x000D_
@NgModule({_x000D_
  imports: [_x000D_
    RouterModule.forRoot(appRoutes)_x000D_
  ],_x000D_
  exports: [RouterModule]_x000D_
})_x000D_
export class AppRoutingModule { }_x000D_
_x000D_
//................................................................_x000D_
_x000D_
//app.module.ts_x000D_
import { AppRoutingModule } from './app-routing.module';_x000D_
_x000D_
@NgModule({_x000D_
  imports: [_x000D_
    AppRoutingModule_x000D_

export class AppModule { }

I fixed this problem today.

• Change your output directory to your WEB-INF/classes folder. (Project/Properties/Java Build Path, Default output folder)
• Assigne the module dependencies. (Project/Properties/Java EE Module Dependencies) they will be copied to the WEB-INF/lib folder where Eclipse looks for the tag lib definitions too.

I hope it helps.

You can use strstr. Example code here.

Note that the returned result is not null terminated.

Sam's solution should be sufficient. I've used combination of both histogram difference and template matching because not one method was working for me 100% of the times. I've given less importance to histogram method though. Here's how I've implemented in simple python script.

import cv2

class CompareImage(object):

    def __init__(self, image_1_path, image_2_path):
        self.minimum_commutative_image_diff = 1
        self.image_1_path = image_1_path
        self.image_2_path = image_2_path

    def compare_image(self):
        image_1 = cv2.imread(self.image_1_path, 0)
        image_2 = cv2.imread(self.image_2_path, 0)
        commutative_image_diff = self.get_image_difference(image_1, image_2)

        if commutative_image_diff < self.minimum_commutative_image_diff:
            print "Matched"
            return commutative_image_diff
        return 10000 //random failure value

    @staticmethod
    def get_image_difference(image_1, image_2):
        first_image_hist = cv2.calcHist([image_1], [0], None, [256], [0, 256])
        second_image_hist = cv2.calcHist([image_2], [0], None, [256], [0, 256])

        img_hist_diff = cv2.compareHist(first_image_hist, second_image_hist, cv2.HISTCMP_BHATTACHARYYA)
        img_template_probability_match = cv2.matchTemplate(first_image_hist, second_image_hist, cv2.TM_CCOEFF_NORMED)[0][0]
        img_template_diff = 1 - img_template_probability_match

        # taking only 10% of histogram diff, since it's less accurate than template method
        commutative_image_diff = (img_hist_diff / 10) + img_template_diff
        return commutative_image_diff


    if __name__ == '__main__':
        compare_image = CompareImage('image1/path', 'image2/path')
        image_difference = compare_image.compare_image()
        print image_difference

A SimpleDateFormat, as its name indicates, formats Dates. Not a Calendar. So, if you want to format a GregorianCalendar using a SimpleDateFormat, you must convert the Calendar to a Date first:

dateFormat.format(calendar.getTime());

And what you see printed is the toString() representation of the calendar. It's intended usage is debugging. It's not intended to be used to display a date in a GUI. For that, use a (Simple)DateFormat.

Finally, to convert from a String to a Date, you should also use a (Simple)DateFormat (its parse() method), rather than splitting the String as you're doing. This will give you a Date object, and you can create a Calendar from the Date by instanciating it (Calendar.getInstance()) and setting its time (calendar.setTime()).

My advice would be: Googling is not the solution here. Reading the API documentation is what you need to do.

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

malloc() and calloc() are functions from the C standard library that allow dynamic memory allocation, meaning that they both allow memory allocation during runtime.

Their prototypes are as follows:

void *malloc( size_t n);
void *calloc( size_t n, size_t t)

There are mainly two differences between the two:

• Behavior: malloc() allocates a memory block, without initializing it, and reading the contents from this block will result in garbage values. calloc(), on the other hand, allocates a memory block and initializes it to zeros, and obviously reading the content of this block will result in zeros.

• Syntax: malloc() takes 1 argument (the size to be allocated), and calloc() takes two arguments (number of blocks to be allocated and size of each block).

The return value from both is a pointer to the allocated block of memory, if successful. Otherwise, NULL will be returned indicating the memory allocation failure.

Example:

int *arr;

// allocate memory for 10 integers with garbage values
arr = (int *)malloc(10 * sizeof(int)); 

// allocate memory for 10 integers and sets all of them to 0
arr = (int *)calloc(10, sizeof(int));

The same functionality as calloc() can be achieved using malloc() and memset():

// allocate memory for 10 integers with garbage values   
arr= (int *)malloc(10 * sizeof(int));
// set all of them to 0
memset(arr, 0, 10 * sizeof(int)); 

Note that malloc() is preferably used over calloc() since it's faster. If zero-initializing the values is wanted, use calloc() instead.

$today = Carbon\Carbon::now()->format('Y-m-d').'%';
->where('created_at', 'like', $today);

Hope it will help you

You need to add a name attribute.

Since this is a multiple select, at the HTTP level, the client just sends multiple name/value pairs with the same name, you can observe this yourself if you use a form with method="GET": someurl?something=1&something=2&something=3.

In the case of PHP, Ruby, and some other library/frameworks out there, you would need to add square braces ([]) at the end of the name. The frameworks will parse that string and wil present it in some easy to use format, like an array.

Apart from manually parsing the request there's no language/framework/library-agnostic way of accessing multiple values, because they all have different APIs

For PHP you can use:

<select name="something[]" id="inscompSelected" multiple="multiple" class="lstSelected">

Simple, create multiple accordian div each representating one anchor tag like:

<div>
<div class="accordion">
<a href = "#">First heading</a>
</div>
<div class="accordion">
<a href = "#">First heading</a>
</div>
</div>

It adds up some markup. But works like a pro...

You don't always want your instance variables to be fully accessible from outside of the class. There are plenty of cases where allowing read access to an instance variable makes sense, but writing to it might not (e.g. a model that retrieves data from a read-only source). There are cases where you want the opposite, but I can't think of any that aren't contrived off the top of my head.

In Visual Studio Professional or Enterprise you can enable CodeLens by doing this:

Tools ? Options ? Text Editor ? All Languages ? CodeLens

This is not available in the Community Edition

You can also use

cd %localhost%

to set the directory to the folder the batch file was opened from. Your script would look like this:

@echo off
cd %localhost%
echo .> dblank.txt

Make sure you set the directory before you use the command to create the text file.

new Guid() makes an "empty" all-0 guid (00000000-0000-0000-0000-000000000000 is not very useful).

Guid.NewGuid() makes an actual guid with a unique value, what you probably want.

I had the same problem on windows "error: failed to execute prompt script (exit code 1) fatal: could not read Username for 'https://github.com': No error" trying to login to github through the login dialog. When I canceled the dialog git asked me for login and password in the command line and it worked fine.

Yes, the function is querySelectorAll (or querySelector for a single element), which allows you to use CSS selectors to find elements.

document.querySelectorAll('[property]'); // All with attribute named "property"
document.querySelectorAll('[property="value"]'); // All with "property" set to "value" exactly.

(Complete list of attribute selectors on MDN.)

This finds all elements with the attribute property. It would be better to specify a tag name if possible:

document.querySelectorAll('span[property]');

You can work around this if necessary by looping through all the elements on the page to see whether they have the attribute set:

var withProperty = [],
    els = document.getElementsByTagName('span'), // or '*' for all types of element
    i = 0;

for (i = 0; i < els.length; i++) {
    if (els[i].hasAttribute('property')) {
        withProperty.push(els[i]);
    }
}

Libraries such as jQuery handle this for you; it's probably a good idea to let them do the heavy lifting.

For anyone dealing with ancient browsers, note that querySelectorAll was introduced to Internet Explorer in v8 (2009) and fully supported in IE9. All modern browsers support it.

Putting this question in the context of NIO and NIO.2 in java 7, async IO is one step more advanced than non-blocking. With java NIO non-blocking calls, one would set all channels (SocketChannel, ServerSocketChannel, FileChannel, etc) as such by calling AbstractSelectableChannel.configureBlocking(false). After those IO calls return, however, you will likely still need to control the checks such as if and when to read/write again, etc.
For instance,

while (!isDataEnough()) {
    socketchannel.read(inputBuffer);
    // do something else and then read again
}

With the asynchronous api in java 7, these controls can be made in more versatile ways. One of the 2 ways is to use CompletionHandler. Notice that both read calls are non-blocking.

asyncsocket.read(inputBuffer, 60, TimeUnit.SECONDS /* 60 secs for timeout */, 
    new CompletionHandler<Integer, Object>() {
        public void completed(Integer result, Object attachment) {...}  
        public void failed(Throwable e, Object attachment) {...}
    }
}

Use the keys method: {"apple" => "fruit", "carrot" => "vegetable"}.keys == ["apple", "carrot"]

$.ajax({
                type: "GET",
                url: "/Home/Downloadexcel/",
                contentType: "application/json; charset=utf-8",
                data: null,
                success: function (Rdata) {
                    debugger;
                    var bytes = new Uint8Array(Rdata.FileContents); 
                    var blob = new Blob([bytes], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
                    var link = document.createElement('a');
                    link.href = window.URL.createObjectURL(blob);
                    link.download = "myFileName.xlsx";
                    link.click();
                },
                error: function (err) {

                }

            });

I have this in my .gitconfig file. It is still a draft, but proved useful as of now. It helps me to always reattach the submodules to their branch.

Delete every things (jar, pom.xml, etc) under your local ~/.m2/repository/phonegap/1.1.0/ directory if you are using a linux OS.

Try using TextView.setRawInputType() it corresponds to the android:inputType attribute.

My understanding is that you actually use script tags with JSONP, sooo...

The first step is to create your function that will handle the JSON:

function hooray(json) {
    // dealin wit teh jsonz
}

Make sure that this function is accessible on a global level.

Next, add a script element to the DOM:

var script = document.createElement('script');
script.src = 'http://domain.com/?function=hooray';
document.body.appendChild(script);

The script will load the JavaScript that the API provider builds, and execute it.

I had the same problem just now and it was solved by simply reinstalling to the latest version of VirtualBox.

For those on Mac OS High Sierra - the installation might fail at first but you need to go to System Preferences > Security & Policy and click on the "Allow" button to allow Oracle installing the software.

Go in the build.gradle and set the version code and name inside the defaultConfig element

defaultConfig { minSdkVersion 9 targetSdkVersion 19 versionCode 1 versionName "1.0" }

ubuntu users:

sudo apt-get install libc6-dev

specially ruby developers that have problem installing gem install json -v '1.8.2' on their VMs

The issue is with the facebook cache and solution is to refresh the facebook cache by going to the link. https://developers.facebook.com/tools/debug/og/object/

and pressing the button "Fetch New Scrape information".

Hope it helps

You could put it in the session:

session_start();
$_SESSION['array_name'] = $array_name;

Or if you want to send it via a form you can serialize it:

<input type='hidden' name='input_name' value="<?php echo htmlentities(serialize($array_name)); ?>" />

$passed_array = unserialize($_POST['input_name']);

Note that to work with serialized arrays, you need to use POST as the form's transmission method, as GET has a size limit somewhere around 1024 characters.

I'd use sessions wherever possible.

Unfortunately this is invalid HTML. An ID has to be unique in the whole HTML file.

When you use Javascript's document.getElementById() it depends on the browser, which element it will return, mostly it's the first with a given ID.

You will have no other chance as to re-assign your IDs, or alternatively using the class attribute.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

in my case it didn't work like following

@Query("select count(e)>0 from MyEntity e where ...")

You can return it as boolean value with following

@Query(value = "SELECT CASE  WHEN count(pl)> 0 THEN true ELSE false END FROM PostboxLabel pl ...")

I need to know way for converting uri to string and string to uri.

Use toString() to convert a Uri to a String. Use Uri.parse() to convert a String to a Uri.

this code doesn't work

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

Use .length refer to http://api.jquery.com/checked-selector/

if ($('input[name="html_elements"]:checked').length === 0) alert("Not checked");
else alert("Checked");

If you don't really like nested functions, you can also iterate over the keys:

myMap : Map<string, boolean>;
for(let key of myMap) {
   if (myMap.hasOwnProperty(key)) {
       console.log(JSON.stringify({key: key, value: myMap[key]}));
   }
}

Note, you have to filter out the non-key iterations with the hasOwnProperty, if you don't do this, you get a warning or an error.

If it's working in the debug, then wait must be the proper solution.
I will suggest to use the explicit wait, as given below:

WebDriverWait wait = new WebDriverWait(new ChromeDriver(), 5);
wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("#Passwd")));

Why stop at just the instance name? You can inventory your SQL Server environment with following:

SELECT  
    SERVERPROPERTY('ServerName') AS ServerName,  
    SERVERPROPERTY('MachineName') AS MachineName,
    CASE 
        WHEN  SERVERPROPERTY('InstanceName') IS NULL THEN ''
        ELSE SERVERPROPERTY('InstanceName')
    END AS InstanceName,
    '' as Port, --need to update to strip from Servername. Note: Assumes Registered Server is named with Port
    SUBSTRING ( (SELECT @@VERSION),1, CHARINDEX('-',(SELECT @@VERSION))-1 ) as ProductName,
    SERVERPROPERTY('ProductVersion') AS ProductVersion,  
    SERVERPROPERTY('ProductLevel') AS ProductLevel,
    SERVERPROPERTY('ProductMajorVersion') AS ProductMajorVersion,
    SERVERPROPERTY('ProductMinorVersion') AS ProductMinorVersion,
    SERVERPROPERTY('ProductBuild') AS ProductBuild,
    SERVERPROPERTY('Edition') AS Edition,
    CASE SERVERPROPERTY('EngineEdition')
        WHEN 1 THEN 'PERSONAL'
        WHEN 2 THEN 'STANDARD'
        WHEN 3 THEN 'ENTERPRISE'
        WHEN 4 THEN 'EXPRESS'
        WHEN 5 THEN 'SQL DATABASE'
        WHEN 6 THEN 'SQL DATAWAREHOUSE'
    END AS EngineEdition,  
    CASE SERVERPROPERTY('IsHadrEnabled')
        WHEN 0 THEN 'The Always On Availability Groups feature is disabled'
        WHEN 1 THEN 'The Always On Availability Groups feature is enabled'
        ELSE 'Not applicable'
    END AS HadrEnabled,
    CASE SERVERPROPERTY('HadrManagerStatus')
        WHEN 0 THEN 'Not started, pending communication'
        WHEN 1 THEN 'Started and running'
        WHEN 2 THEN 'Not started and failed'
        ELSE 'Not applicable'
    END AS HadrManagerStatus,
    CASE SERVERPROPERTY('IsSingleUser') WHEN 0 THEN 'No' ELSE 'Yes' END AS InSingleUserMode,
    CASE SERVERPROPERTY('IsClustered')
        WHEN 1 THEN 'Clustered'
        WHEN 0 THEN 'Not Clustered'
        ELSE 'Not applicable'
    END AS IsClustered,
    '' as ServerEnvironment,
    '' as ServerStatus,
    '' as Comments

for(n in 1:5) {

Try creating a javascript function which runs this:

document.getElementById("youriframeid").contentWindow.location.reload(true);

Or maybe use an HTML workaround:

<html>
<body>
<center>
      <a href="pagename.htm" target="middle">Refresh iframe</a>
      <p>
        <iframe src="pagename.htm" name="middle">
      </p>
</center>
</body>
</html>

Both might be what you're looking for...

use checked : true, false property of the checkbox.

jQuery:

if($('input[type=checkbox]').is(':checked')) {
    $(this).prop('checked',true);
} else {
    $(this).prop('checked',false);
}

perl -ne 'chomp; printf qq/%s="%s"\n/, split(/\s*:\s*/,$_,2)' file.yml > file.sh

Be Careful while using INPUT. This event fires on focus and on blur in IE 11. But it is triggered on change in other browsers.

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

another bit of code here:

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

Refer this link for more info

CODEPEN

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

Here is how I did it.

Populate the text box values in the Page Init event as opposed to using the Postback.

protected void Page_Init(object sender, EventArgs e)
{
    DropDownTitle();
}

In SQL Server Management Studio 2008 (R2) and newer, you can Right Click on the

DB -> Tasks -> Generate Scripts

• Select the tables you want to DROP.

• Select "Save to new query window".

• Click on the Advanced button.

• Set Script DROP and CREATE to Script DROP.

• Set Script Foreign Keys to True.

• Click OK.

• Click Next -> Next -> Finish.

• View the script and then Execute.

As others already said, there seems to be no good solution to do that easily.
But to keep your code clean I suggest creating a seperate class that hides the ugly XAML.

How to use after we created the ButtonEx-class:

Tip: You can add an UserControl with name "ButtonEx" to your project in VS Studio and then copy paste the stuff above in.

Probably depending on the XML feed you may/may not need to use __toString(); I had to use the __toString() otherwise it is returning the string inside an SimpleXMLElement. Maybe I need to drill down the object further ...

There is solution with all necessary details for Windows 7 x64:

It is in French, but you can understand everything! I solved same problem, even don't speak French. :-)

Many answers forget to mention that you need to add new version of php_curl.dll file from this location: http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

I added new version of php_curl.dll from archive php_curl-5.4.3-VC9-x64.zip to folders: C:\wamp\bin\php\php5.4.3\ext and C:\Windows\System32 and everything was fine!

Try swapspace http://pqxx.org/development/swapspace/

Most distros have it packaged.

On EC2 you might want to change "swappath" to /mnt or high-iops disk.

To see what version you have on your Mac(Window also can run that code.), run react-native -v and you should get something like this:

If you want to know what version your project is running, look in /node_modules/react-native/package.json and look for the version key:

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

use ONLY

function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

.innerHTML() sets or gets the HTML syntax describing the element's descendants., All you need is an object here.

Demo

public long getFibonacci( int number) {
    if ( number <=2) {
        return 1;
    }
    long lRet = 0;
    lRet = getFibonacci( number -1) + getFibonacci( number -2);
    return lRet;
}

sign of remainder will be same as the divisible and the sign of modulus will be same as divisor.

Remainder is simply the remaining part after the arithmetic division between two integer number whereas Modulus is the sum of remainder and divisor when they are oppositely signed and remaining part after the arithmetic division when remainder and divisor both are of same sign.

Example of Remainder:

10 % 3 = 1 [here divisible is 10 which is positively signed so the result will also be positively signed]

-10 % 3 = -1 [here divisible is -10 which is negatively signed so the result will also be negatively signed]

10 % -3 = 1 [here divisible is 10 which is positively signed so the result will also be positively signed]

-10 % -3 = -1 [here divisible is -10 which is negatively signed so the result will also be negatively signed]

Example of Modulus:

5 % 3 = 2 [here divisible is 5 which is positively signed so the remainder will also be positively signed and the divisor is also positively signed. As both remainder and divisor are of same sign the result will be same as remainder]

-5 % 3 = 1 [here divisible is -5 which is negatively signed so the remainder will also be negatively signed and the divisor is positively signed. As both remainder and divisor are of opposite sign the result will be sum of remainder and divisor -2 + 3 = 1]

5 % -3 = -1 [here divisible is 5 which is positively signed so the remainder will also be positively signed and the divisor is negatively signed. As both remainder and divisor are of opposite sign the result will be sum of remainder and divisor 2 + -3 = -1]

-5 % -3 = -2 [here divisible is -5 which is negatively signed so the remainder will also be negatively signed and the divisor is also negatively signed. As both remainder and divisor are of same sign the result will be same as remainder]

I hope this will clearly distinguish between remainder and modulus.

refer here: https://nathanhoad.net/how-to-colours-in-git/

steps:

1. Open ~/.gitconfig for editing

   vi ~/.gitconfig

2. Paste following code:

   [color]
     ui = auto
   [color "branch"]
     current = yellow reverse
     local = yellow
     remote = green
   [color "diff"]
     meta = yellow bold
     frag = magenta bold
     old = red bold
     new = green bold
   [color "status"]
     added = yellow
     changed = green
     untracked = cyan
   

3. Save the file.

Just change any file in your local repo and do

git status

tl;dr

1. In ECMAScript 5, it is not possible.
2. In ECMAScript 2015, it is possible with Maps.
3. In ECMAScript 2017, it would be readily available.

ECMAScript 5:

No, its not possible with objects.

You should either iterate with for..in, or Object.keys, like this

for (var key in dictionary) {
    // check if the property/key is defined in the object itself, not in parent
    if (dictionary.hasOwnProperty(key)) {           
        console.log(key, dictionary[key]);
    }
}

Note: The if condition above is necessary, only if you want to iterate the properties which are dictionary object's very own. Because for..in will iterate through all the inherited enumerable properties.

Or

Object.keys(dictionary).forEach(function(key) {
    console.log(key, dictionary[key]);
});

ECMAScript 2015

In ECMAScript 2015, you can use Map objects and iterate them with Map.prototype.entries. Quoting example from that page,

var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

var mapIter = myMap.entries();

console.log(mapIter.next().value); // ["0", "foo"]
console.log(mapIter.next().value); // [1, "bar"]
console.log(mapIter.next().value); // [Object, "baz"]

Or iterate with for..of, like this

'use strict';

var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

for (const entry of myMap.entries()) {
  console.log(entry);
}

Output

[ '0', 'foo' ]
[ 1, 'bar' ]
[ {}, 'baz' ]

Or

for (const [key, value] of myMap.entries()) {
  console.log(key, value);
}

Output

0 foo
1 bar
{} baz

ECMAScript 2017

ECMAScript 2017 would introduce a new function Object.entries. You can use this to iterate the object as you wanted.

'use strict';

const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
  console.log(key, value);
}

Output

a 1
b 2
c 3

In javascript the "+" operator is used to add numbers or to concatenate strings. if one of the operands is a string "+" concatenates, and if it is only numbers it adds them.

example:

1+2+3 == 6
"1"+2+3 == "123"

Here's my solution:

REM make sure ERRORLEVEL is 0
TYPE NUL

REM try to PUSHD into the path (store current dir and switch to another one)
PUSHD "insert path here..." >NUL 2>&1

REM if ERRORLEVEL is still 0, it's most definitely a directory
IF %ERRORLEVEL% EQU 0 command...

REM if needed/wanted, go back to previous directory
POPD

I ran into the same issue, for whatever reason Visual Studio did not update the web config when I first added the service. I found that updating the Service Reference also fixed this issue.

Steps:

1. Navigate to the Service Reference Folder
2. Expand it
3. Right Click and Select update Service Reference
4. Observe web Config be updated

Pandas >= 0.25.0, named aggregations

Since pandas version 0.25.0 or higher, we are moving away from the dictionary based aggregation and renaming, and moving towards named aggregations which accepts a tuple. Now we can simultaneously aggregate + rename to a more informative column name:

Example:

df = pd.DataFrame(np.random.rand(4,4), columns=list('abcd'))
df['group'] = [0, 0, 1, 1]

          a         b         c         d  group
0  0.521279  0.914988  0.054057  0.125668      0
1  0.426058  0.828890  0.784093  0.446211      0
2  0.363136  0.843751  0.184967  0.467351      1
3  0.241012  0.470053  0.358018  0.525032      1

Apply GroupBy.agg with named aggregation:

df.groupby('group').agg(
             a_sum=('a', 'sum'),
             a_mean=('a', 'mean'),
             b_mean=('b', 'mean'),
             c_sum=('c', 'sum'),
             d_range=('d', lambda x: x.max() - x.min())
)

          a_sum    a_mean    b_mean     c_sum   d_range
group                                                  
0      0.947337  0.473668  0.871939  0.838150  0.320543
1      0.604149  0.302074  0.656902  0.542985  0.057681

I'm using ng2-carouselamos (Angular 8 and Bootstrap 4)

Taking these steps fixed my problem:

1. Implement AfterViewChecked
2. Add constructor(private changeDetector : ChangeDetectorRef ) {}
3. Then ngAfterViewChecked(){ this.changeDetector.detectChanges(); }

I remember the way you described it using Visual Basic 6.0. In Visual Studio, the only way I have found so far is by specifying a breakpoint condition.

The .git folder is only stored in the root directory of the repo, not all the sub-directories like subversion. You should be able to just delete that one folder, unless you are using Submodules...then they will have one too.

To input AN ENTIRE LINE containing lot of spaces you can use getline(cin,string_variable);

eg:

string input;
getline(cin, input);

This format captures all the spaces in the sentence untill return is pressed

If you don't use the STL, then the code looks a lot bit like C.

#include <cstdlib>
#include <new>

template< class T >
void append_to_array( T *&arr, size_t &n, T const &obj ) {
    T *tmp = static_cast<T*>( std::realloc( arr, sizeof(T) * (n+1) ) );
    if ( tmp == NULL ) throw std::bad_alloc( __FUNCTION__ );
       // assign things now that there is no exception
    arr = tmp;
    new( &arr[ n ] ) T( obj ); // placement new
    ++ n;
}

T can be any POD type, including pointers.

Note that arr must be allocated by malloc, not new[].

The HAVING clause was added to SQL because the WHERE keyword could not be used with aggregate functions.

Check out this w3schools link for more information

Syntax:

SELECT column_name, aggregate_function(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name
HAVING aggregate_function(column_name) operator value

A query such as this:

SELECT column_name, COUNT( column_name ) AS column_name_tally
  FROM table_name
 WHERE column_name < 3
 GROUP 
    BY column_name
HAVING COUNT( column_name ) >= 3;

...may be rewritten using a derived table (and omitting the HAVING) like this:

SELECT column_name, column_name_tally
  FROM (
        SELECT column_name, COUNT(column_name) AS column_name_tally
          FROM table_name
         WHERE column_name < 3
         GROUP 
            BY column_name
       ) pointless_range_variable_required_here
 WHERE column_name_tally >= 3;

You can also add the --cached flag to auco's answer to maintain local .DS_store files, as Edward Newell mentioned in his original answer. The modified command looks like this: find . -name .DS_Store -print0 | xargs -0 git rm --cached --ignore-unmatch ..cheers and thanks!

You can store the array using serialize/unserialize. With that solution they cannot easily be used from other programming languages, so you may consider using json_encode/json_decode instead (which gives you a widely supported format). Avoid using implode/explode for this since you'll probably end up with bugs or security flaws.

Note that this makes your table non-normalized, which may be a bad idea since you cannot easily query the data. Therefore consider this carefully before going forward. May you need to query the data for statistics or otherwise? Are there other reasons to normalize the data?

Also, don't save the raw $_POST array. Someone can easily make their own web form and post data to your site, thereby sending a really large form which takes up lots of space. Save those fields you want and make sure to validate the data before saving it (so you won't get invalid values).

If both Column are numeric Then Use This code

Just Cast Column As Varchar(Size)

Example:

Select (Cast(Col1 as Varchar(20)) + '-' + Cast(Col2 as Varchar(20))) As Col3 from Table

You could also use a block

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
    [object method]; 
});

Most of time you will want to use dispatch_get_main_queue, although if there is no UI in the method you could use a global queue.

Edit:

Swift 3 version:

DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
    object.method()
}

Equally, DispatchQueue.global().asyncAfter(... might also be a good option.

If your are using Apache you may always count on

$_SERVER["REQUEST_SCHEME"]

to verify the scheme of the URL requested. But, as mentioned in other answers, it is prudent to verify other parameters before assuming SSL is really being used.

Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).

Either way works, I like to put that logic in the query so the report has to do less.

Try below code.

Random rnd = new Random();
int month = rnd.Next(1, 13); // creates a number between 1 and 12
int dice = rnd.Next(1, 7); // creates a number between 1 and 6
int card = rnd.Next(52); // creates a number between 0 and 51

It's also possible by using rsync, for example:

rsync -va --delete-after src/ dst/

where:

• -v, --verbose: increase verbosity
• -a, --archive: archive mode; equals -rlptgoD (no -H,-A,-X)
• --delete-after: delete files on the receiving side be done after the transfer has completed

If you've root privileges, prefix with sudo to override potential permission issues.

Something like this:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString
[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];

Then to retrieve:

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];

You should really check out Apple's NSUserDefaults Class Reference and also maybe this tutorial: iPhone Programming Tutorial – Saving/Retrieving Data Using NSUserDefaults

I've seen both methods been used in seed files.

// Uncomment the below to wipe the table clean before populating

DB::table('table_name')->truncate();

//or

DB::table('table_name')->delete();

Even though you can not use the first one if you want to set foreign keys.

Cannot truncate a table referenced in a foreign key constraint

So it might be a good idea to use the second one.

Yet another approach.

The following is now possible thanks to the recent PHP 7 version.

$theStdClass = (object) [
  'a' => 'Alpha',
  'b' => 'Bravo',
  'c' => 'Charlie',
  'd' => 'Delta',
];

$foo = new class($theStdClass)  {
  public function __construct($data) {
    if (!is_array($data)) {
      $data = (array) $data;
    }

    foreach ($data as $prop => $value) {
      $this->{$prop} = $value;
    }
  }
  public function word4Letter($letter) {
    return $this->{$letter};
  }
};

print $foo->word4Letter('a') . PHP_EOL; // Alpha
print $foo->word4Letter('b') . PHP_EOL; // Bravo
print $foo->word4Letter('c') . PHP_EOL; // Charlie
print $foo->word4Letter('d') . PHP_EOL; // Delta
print $foo->word4Letter('e') . PHP_EOL; // PHP Notice:  Undefined property

In this example, $foo is being initialized as an anonymous class that takes one array or stdClass as only parameter for the constructor.

Eventually, we loop through the each items contained in the passed object and dynamically assign then to an object's property.

To make this approch event more generic, you can write an interface or a Trait that you will implement in any class where you want to be able to cast an stdClass.

Looks like Xcode hides that menu when the window is a certain size. You have to make your window quite large before it comes back.

Depending on your needs, like if you want to allow the data to eventually expire or set limitations on how many records to store, you could also look at https://github.com/jmdobry/angular-cache which allows you to define if the cache sits in memory, localStorage, or sessionStorage.

that function replaces only one occurrence.. if you need to replace multiple occurrences you should try this function: http://phpjs.org/functions/str_replace:527

Not necessarily. see the Hans Kesting answer:

city_name = city_name.replace(/ /gi,'_');

I found a solution.

background-size:100% auto;

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

If all you want is to check if key exists or not

h = {'a': 1}
'b' in h # returns False

If you want to check if there is a value for key

h.get('b') # returns None

Return a default value if actual value is missing

h.get('b', 'Default value')

For me, it was very difficult to identify the problem because of a large number of methods and class involved.

What I did is commented (removed) some methods from the WebService interface and try, and then comment another bunch of methods and try, I kept doing this until I found the method that cause the problem.

In my case, it was using a complex object which cannot be serialized.

Good luck!

// copy /tmp/abc.txt to /tmp/abc.txt (target path)

// username and password of 10.1.1.2 is "username" and "password"

sshpass -p "password" scp /tmp/abc.txt [email protected]:/tmp/abc.txt

// install sshpass (ubuntu)

sudo apt-get install sshpass

I added both declarations on the a href which worked in outlook and gmail apps. outlook ignores the !important and gmail needs it. Web versions of email work with both/either.

text-decoration: none !important; text-decoration: none;

Don't use add for strings, you should define a custom tag like this :

Create a file : <appname>\templatetags\<appname>_extras.py

from django import template

register = template.Library()

@register.filter
def addstr(arg1, arg2):
    """concatenate arg1 & arg2"""
    return str(arg1) + str(arg2)

and then use it as @Steven says

{% load <appname>_extras %}

{% with "shop/"|addstr:shop_name|addstr:"/base.html" as template %}
    {% include template %}
{% endwith %}

Reason for avoiding add:

According to the docs

This filter will first try to coerce both values to integers... Strings that can be coerced to integers will be summed, not concatenated...

If both variables happen to be integers, the result would be unexpected.

Quick fix: Change how excel converts imported files. Go to 'File', then 'Options', then 'Advanced'. Scroll down and uncheck 'Use system seperators'. Also change 'Decimal separator' to '.' and 'Thousands separator' to ',' . Then simply 're-save' your file in the CSV (Comma delimited) format. The root cause is usually associated with how the csv file is created. Trust that helps. Point is, why use extra code if not necessary? Cross-platform understanding and integration is key in engineering/development.

You'll have to give an ID to the div you want to show/hide, then use this code:

html:

<div id="one">
    <div id="tow">
        This is text
    </div>
    <button onclick="javascript:showDiv();">Click to show div</button>
</div>

javascript:

function showDiv() {
    div = document.getElementById('tow');
    div.style.display = "block";
}

CSS:

?#tow { display: none; }?

Simply copy your script and put under """ your entire code """ ...

specify this line in a variable.. like,

a = """ your entire code """
print a.replace('    ','    ') # first 4 spaces tab second four space from space bar

print a.replace('here please press tab button it will insert some space"," here simply press space bar four times")
# here we replacing tab space by four char space as per pep 8 style guide..

now execute this code, in sublime using ctrl+b, now it will print indented code in console. that's it

it looks like you need a rule very similar to your checked rule

http://jsfiddle.net/VWBN4/3

#ck-button input:hover + span {
    background-color:#191;
    color:#fff;
}

and for hover and clicked state:

#ck-button input:checked:hover + span {
    background-color:#c11;
    color:#fff;
}

the order is important though.

if you really want an array instead you can use:

$getvidids->result_array()

which would return the same information as an associative array.

While the accepted answer is very true, just want to point out that AllowTransparency has some downfalls. It does not allow child window controls to show up, ie WebBrowser, and it usually forces software rendering which can have negative performance effects.

There is a better work around though.

When you want to create a window with no border that is resizeable and is able to host a WebBrowser control or a Frame control pointed to a URL you simply couldn't, the contents of said control would show empty.

I found a workaround though; in the Window, if you set the WindowStyle to None, ResizeMode to NoResize (bear with me, you will still be able to resize once done) then make sure you have UNCHECKED AllowsTransparency you will have a static sized window with no border and will show the browser control.

Now, you probably still want to be able to resize right? Well we can to that with a interop call:

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

    [DllImportAttribute("user32.dll")]
    public static extern bool ReleaseCapture();

    //Attach this to the MouseDown event of your drag control to move the window in place of the title bar
    private void WindowDrag(object sender, MouseButtonEventArgs e) // MouseDown
    {
        ReleaseCapture();
        SendMessage(new WindowInteropHelper(this).Handle,
            0xA1, (IntPtr)0x2, (IntPtr)0);
    }

    //Attach this to the PreviewMousLeftButtonDown event of the grip control in the lower right corner of the form to resize the window
    private void WindowResize(object sender, MouseButtonEventArgs e) //PreviewMousLeftButtonDown
    {
        HwndSource hwndSource = PresentationSource.FromVisual((Visual)sender) as HwndSource;
        SendMessage(hwndSource.Handle, 0x112, (IntPtr)61448, IntPtr.Zero);
    }

And voila, A WPF window with no border and still movable and resizable without losing compatibility with with controls like WebBrowser

function timeago(date) {
    var seconds = Math.floor((new Date() - date) / 1000);
    if(Math.round(seconds/(60*60*24*365.25)) >= 2) return Math.round(seconds/(60*60*24*365.25)) + " years ago";
    else if(Math.round(seconds/(60*60*24*365.25)) >= 1) return "1 year ago";
    else if(Math.round(seconds/(60*60*24*30.4)) >= 2) return Math.round(seconds/(60*60*24*30.4)) + " months ago";

    else if(Math.round(seconds/60) >= 2) return Math.round(seconds/60) + " minutes ago";
    else if(Math.round(seconds/60) >= 1) return "1 minute ago";
    else if(seconds >= 2)return seconds + " seconds ago";
    else return seconds + "1 second ago";
}

This process allows you to completely reproduce any Travis build job on your computer. Also, you can interrupt the process at any time and debug. Below is an example where I perfectly reproduce the results of job #191.1 on php-school/cli-menu .

Prerequisites

• You have public repo on GitHub
• You ran at least one build on Travis
• You have Docker set up on your computer

Set up the build environment

Reference: https://docs.travis-ci.com/user/common-build-problems/

1. Make up your own temporary build ID

   BUILDID="build-$RANDOM"
   

2. View the build log, open the show more button for WORKER INFORMATION and find the INSTANCE line, paste it in here and run (replace the tag after the colon with the newest available one):

   INSTANCE="travisci/ci-garnet:packer-1512502276-986baf0"
   

3. Run the headless server

   docker run --name $BUILDID -dit $INSTANCE /sbin/init
   

4. Run the attached client

   docker exec -it $BUILDID bash -l
   

Run the job

Now you are now inside your Travis environment. Run su - travis to begin.

This step is well defined but it is more tedious and manual. You will find every command that Travis runs in the environment. To do this, look for for everything in the right column which has a tag like 0.03s.

On the left side you will see the actual commands. Run those commands, in order.

Result

Now is a good time to run the history command. You can restart the process and replay those commands to run the same test against an updated code base.

• If your repo is private: ssh-keygen -t rsa -b 4096 -C "YOUR EMAIL REGISTERED IN GITHUB" then cat ~/.ssh/id_rsa.pub and click here to add a key
• FYI: you can git pull from inside docker to load commits from your dev box before you push them to GitHub
• If you want to change the commands Travis runs then it is YOUR responsibility to figure out how that translates back into a working .travis.yml.
• I don't know how to clean up the Docker environment, it looks complicated, maybe this leaks memory

1. Change to folder %PROGRAMFILES%\Git\etc
2. Edit file profile
3. Add to first line HOME="c:\location_were_you_want_gitconfig"
4. Done

Note: The file permissions are usually restricted, so change them accordingly or you won't be able to save your changes.

foreach (EMyEnum val in Enum.GetValues(typeof(EMyEnum)))

Its worth noting - and I only found this out after nearly 9 years of PHP coding that the best way of checking any variable exists is using the empty() function. This is because it doesn't generate errors and even though you turn them off - PHP still generates them! empty() however won't return errors if the variable doesn't exist. So I believe the correct answer is not to check if its null but to do the following

if (!empty($var) && is_null($var))

Note the PHP manual

variable is considered empty if it does not exist or if its value equals FALSE

As opposed to being null which is handy here!

put this line in parent construct : $this->load->database();

function  __construct() {
    parent::__construct();
    $this->load->library('lib_name');
    $model=array('model_name');
    $this->load->model($model);
    $this->load->database();
}

this way.. it should work..

Simple code to check pointer aliasing:

int main () {
    int a = 10, b = 20;
    int *p1, *p2, *p3, *p4;

    p1 = &a;
    p2 = &a;
    if(p1 == p2){
        std::cout<<"p1 and p2 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p1 and p2 do not alias each other"<<std::endl;
    }
    //------------------------
    p3 = &a;
    p4 = &b;
    if(p3 == p4){
        std::cout<<"p3 and p4 alias each other"<<std::endl;
    }
    else{
        std::cout<<"p3 and p4 do not alias each other"<<std::endl;
    }
    return 0;
}

Output:

p1 and p2 alias each other
p3 and p4 do not alias each other

If you have more as one Project in your Project Map use THE SAME hard coded PathFile PDB Name in all your Sub-Projects:

Use e.g.

D:\Visual Studio Projects\my_app\MyFile.pdb

Dont use e.g.

$(IntDir)\MyFile.pdb

in all the Sub-Projects !!!

From the documentation:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

From the mailing list thread linked by @kindall in a comment to the question:

I haven't tried to repro this particular example, but the reason is that we don't want to have to call getpwd() on every import nor do we want to have some kind of in-process variable to cache the current directory. (getpwd() is relatively slow and can sometimes fail outright, and trying to cache it has a certain risk of being wrong.)

What we do instead, is code in site.py that walks over the elements of sys.path and turns them into absolute paths. However this code runs before '' is inserted in the front of sys.path, so that the initial value of sys.path is ''.

For the rest of this, consider sys.path not to include ''.

So, if you are outside the part of sys.path that contains the module, you'll get an absolute path. If you are inside the part of sys.path that contains the module, you'll get a relative path.

If you load a module in the current directory, and the current directory isn't in sys.path, you'll get an absolute path.

If you load a module in the current directory, and the current directory is in sys.path, you'll get a relative path.

You can use the Element.scrollTo() method.

It can be animated using the built-in browser/OS animation, so it's super smooth.

function scrollToBottom() {
    const scrollContainer = document.getElementById('container');
    scrollContainer.scrollTo({
        top: scrollContainer.scrollHeight,
        left: 0,
        behavior: 'smooth'
    });
}

// initialize dummy content
const scrollContainer = document.getElementById('container');
const numCards = 100;
let contentInnerHtml = '';
for (let i=0; i<numCards; i++) {
  contentInnerHtml += `<div class="card mb-2"><div class="card-body">Card ${i + 1}</div></div>`;
}
scrollContainer.innerHTML = contentInnerHtml;

.overflow-y-scroll {
  overflow-y: scroll;
}

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="d-flex flex-column vh-100">
  <div id="container" class="overflow-y-scroll flex-grow-1"></div>
  <div>
    <button class="btn btn-primary" onclick="scrollToBottom()">Scroll to bottom</button>
  </div>
</div>

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

Simplest Way that i have tried Just now

from datetime import datetime
from django.utils import timezone





current = timezone.now()
if current.month == 1:
     month = 12
else:
     month = current.month - 1
current = datetime(current.year, month, current.day)

Wikipedia has the following information about USING:

The USING construct is more than mere syntactic sugar, however, since the result set differs from the result set of the version with the explicit predicate. Specifically, any columns mentioned in the USING list will appear only once, with an unqualified name, rather than once for each table in the join. In the case above, there will be a single DepartmentID column and no employee.DepartmentID or department.DepartmentID.

Tables that it was talking about:

The Postgres documentation also defines them pretty well:

The ON clause is the most general kind of join condition: it takes a Boolean value expression of the same kind as is used in a WHERE clause. A pair of rows from T1 and T2 match if the ON expression evaluates to true.

The USING clause is a shorthand that allows you to take advantage of the specific situation where both sides of the join use the same name for the joining column(s). It takes a comma-separated list of the shared column names and forms a join condition that includes an equality comparison for each one. For example, joining T1 and T2 with USING (a, b) produces the join condition ON T1.a = T2.a AND T1.b = T2.b.

Furthermore, the output of JOIN USING suppresses redundant columns: there is no need to print both of the matched columns, since they must have equal values. While JOIN ON produces all columns from T1 followed by all columns from T2, JOIN USING produces one output column for each of the listed column pairs (in the listed order), followed by any remaining columns from T1, followed by any remaining columns from T2.

Use $HTTP_RAW_POST_DATA instead of $_POST.

It will give you POST data as is.

You will be able to decode it using json_decode() later.

If you wish to not show the button moving back and forth, you can put the original placement into your code then just check against those. Turn off screen updating when button is clicked, check to see if the the placement is different on the control, change it back, if needed, turn screen updating back on

DP

SIGINT can be send to program using windows-kill, by syntax windows-kill -SIGINT PID, where PID can be obtained by Microsoft's pslist.

Regarding catching SIGINTs, if your program is in Python then you can implement SIGINT processing/catching like in this solution.

Check out the pack URI syntax. You want something like this:

<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/Subfolder/YourResourceFile.xaml"/>

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

You need to set oracle to listen on all ip addresses (by default, it listens only to localhost connections.)

Step 1 - Edit listener.ora

This file is located in:

• Windows: %ORACLE_HOME%\network\admin\listener.ora.
• Linux: $ORACLE_HOME/network/admin/listener.ora

Replace localhost with 0.0.0.0

# ...

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    )
  )

# ...

Step 2 - Restart Oracle services

• Windows: WinKey + r

  services.msc
  

• Linux (CentOs):

  sudo systemctl restart oracle-xe
  

If you have ERROR 1064 (42000) or ERROR 1046 (3D000): No database selected in Mysql 5.7, you must specify the location of the user table, the location is mysql.table_name Then the code will work.

sudo mysql -u root -p

UPDATE mysql.user SET authentication_string=password('elephant7') WHERE user='root';

Use

$(document).ready(function() {
    $('#createFormId').on('show.bs.modal', function(event) {
        $("#cafeId").val($(event.relatedTarget).data('id'));
    });
});

In a Groovy script the scoping can be different than expected. That is because a Groovy script in itself is a class with a method that will run the code, but that is all done runtime. We can define a variable to be scoped to the script by either omitting the type definition or in Groovy 1.8 we can add the @Field annotation.

import groovy.transform.Field

var1 = 'var1'
@Field String var2 = 'var2'
def var3 = 'var3'

void printVars() {
    println var1
    println var2
    println var3 // This won't work, because not in script scope.
}

ld is trying to find libcrypto.sowhich is not present as seen in your locate output. You can make a copy of the libcrypto.so.0.9.8 and name it as libcrypto.so. Put this is your ld path. ( If you do not have root access then you can put it in a local path and specify the path manually )

if ( $("#your_select_id option[value=<enter_value_here>]").length == 0 ){
  alert("option doesn't exist!");
}

I noticed this wasn't working with a static-first-then-reverse-proxy setup. Here's what that looks like:

location @app {
  proxy_pass http://localhost:3000$request_uri;
}

location / {
  try_files $uri $uri/ @app;
  error_page 405 @app;
}

Regex is not on the list of search features, and it was on (more or less, as Better message search functionality (i.e. Wildcard and partial word search)) the list of pre-canned feature requests, so the answer is "you cannot do this via the Gmail web UI" :-(

There are no current Labs features which offer this. SIEVE filters would be another way to do this, that too was not supported, there seems to no longer be any definitive statement on SIEVE support in the Gmail help.

Updated for link rot The pre-canned list of feature requests was, er canned, the original is on archive.org dated 2012, now you just get redirected to a dumbed down page telling you how to give feedback. Lack of SIEVE support was covered in answer 78761 Does Gmail support all IMAP features?, since some time in 2015 that answer silently redirects to the answer about IMAP client configuration, archive.org has a copy dated 2014.

With the current search facility brackets of any form () {} [] are used for grouping, they have no observable effect if there's just one term within. Using (aaa|bbb) and [aaa|bbb] are equivalent and will both find words aaa or bbb. Most other punctuation characters, including \, are treated as a space or a word-separator, + - : and " do have special meaning though, see the help.

As of 2016, only the form "{term1 term2}" is documented for this, and is equivalent to the search "term1 OR term2".

You can do regex searches on your mailbox (within limits) programmatically via Google docs: http://www.labnol.org/internet/advanced-gmail-search/21623/ has source showing how it can be done (copy the document, then Tools > Script Editor to get the complete source).

You could also do this via IMAP as described here: Python IMAP search for partial subject and script something to move messages to different folder. The IMAP SEARCH verb only supports substrings, not regex (Gmail search is further limited to complete words, not substrings), further processing of the matches to apply a regex would be needed.

For completeness, one last workaround is: Gmail supports plus addressing, if you can change the destination address to [email protected] it will still be sent to your mailbox where you can filter by recipient address. Make sure to filter using the full email address to:[email protected]. This is of course more or less the same thing as setting up a dedicated Gmail address for this purpose :-)

This should do it

RedirectPermanent /contact.php /contact-us.php 

Mozilla Developer Network's Guide to Regular Expressions provides this escaping function:

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Sub CheckValues1()
    Dim rwIndex As Integer
    Dim colIndex As Integer
    For rwIndex = 1 To 10
            For colIndex = 1 To 5
                If Cells(rwIndex, colIndex).Value <> 0 Then _
                    Cells(rwIndex, colIndex).Value = 0
            Next colIndex
    Next rwIndex
End Sub

Found this snippet on http://www.java2s.com/Code/VBA-Excel-Access-Word/Excel/Checksvaluesinarange10rowsby5columns.htm It seems to be quite useful as a function to illustrate the means to check values in cells in an ordered fashion.

Just imagine it as being a 2d Array of sorts and apply the same logic to loop through cells.

In order to approach to Modular design pattern, you need to understand these concept first:

Immediately-Invoked Function Expression (IIFE):

(function() {
      // Your code goes here 
}());

There are two ways you can use the functions. 1. Function declaration 2. Function expression.

Here are using function expression.

What is namespace? Now if we add the namespace to the above piece of code then

var anoyn = (function() {
}());

What is closure in JS?

It means if we declare any function with any variable scope/inside another function (in JS we can declare a function inside another function!) then it will count that function scope always. This means that any variable in outer function will be read always. It will not read the global variable (if any) with the same name. This is also one of the objective of using modular design pattern avoiding naming conflict.

var scope = "I am global";
function whatismyscope() {
    var scope = "I am just a local";
    function func() {return scope;}
    return func;
}
whatismyscope()()

Now we will apply these three concepts I mentioned above to define our first modular design pattern:

var modularpattern = (function() {
    // your module code goes here
    var sum = 0 ;

    return {
        add:function() {
            sum = sum + 1;
            return sum;
        },
        reset:function() {
            return sum = 0;    
        }  
    }   
}());
alert(modularpattern.add());    // alerts: 1
alert(modularpattern.add());    // alerts: 2
alert(modularpattern.reset());  // alerts: 0

jsfiddle for the code above.

The objective is to hide the variable accessibility from the outside world.

Hope this helps. Good Luck.

This is to get it working as an ALIAS, not a Symbolic link!

This will allow you to run additional commands in the terminal without interrupting the subl session. Using many of the symbolic link answers here (ln -s), cause the terminal process to endure while using Sublime text. If you want the separation, create an alias in the Bash profile like so:

1. Test subl from your ST installation:

   First, navigate to a folder in Terminal that you want ST to open and enter the following command:

   /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl .
   

   NOTE: You may need to replace Sublime\ Text.app in the command above to Sublime\ Text\ 3.app or Sublime\ Text\ 2.app depending upon where the application is stored in your Applications directory. The . at the end of the above command opens the current working directory you are located in (again make sure you're in a directory that only contains a few files!).

   If you DO NOT get Sublime Text opening your current working directory then the next set of steps will NOT work. If nothing happens or you get an error from Terminal it will be because it couldn't find the Sublime Text application. This would mean that you would have to check what you've typed (spelling, etc.) OR that Sublime Text isn't installed!

2. Check and update ".bash_profile":

   Now add the alias in your Bash Profile. Open it via vim ~/.bash_profile. These are the following lines that pertain to having subl work on the command line for Sublime Text:

   ## For Sublime Text 3 alias
   alias subl='/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl'
   ## For Sublime Text global editor preference **Optional
   export EDITOR='subl -w'
   

   I suggest always commenting your code in here with ##. The second line is OPTIONAL and just sets Sublime Text as the default editor. The flag -w has been added and you can find out more about flags by going to the Sublime Text docs: ST3 subl or ST2 subl

There are two ways to doing the same:

1. You may set the value of android:divider="#FFCCFF" in layout xml file. With this you also have to specify height of divider like this android:dividerHeight="5px".

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent">
   
     <ListView 
     android:id="@+id/lvMyList"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:divider="#FFCCFF"
     android:dividerHeight="5px"/>
   
   </LinearLayout>
   

2. You may also do this by programmatically...

   ListView listView = getListView();
   ColorDrawable myColor = new ColorDrawable(
       this.getResources().getColor(R.color.myColor)
   );
   listView.setDivider(myColor);
   listView.setDividerHeight();
   

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }
        }
    }
    return promo;
}

Use os.path.join to combine the path to the Documents directory with the completeName (filename?) supplied by the user.

import os
with open(os.path.join('/path/to/Documents',completeName), "w") as file1:
    toFile = raw_input("Write what you want into the field")
    file1.write(toFile)

If you want the Documents directory to be relative to the user's home directory, you could use something like:

os.path.join(os.path.expanduser('~'),'Documents',completeName)

Others have proposed using os.path.abspath. Note that os.path.abspath does not resolve '~' to the user's home directory:

In [10]: cd /tmp
/tmp

In [11]: os.path.abspath("~")
Out[11]: '/tmp/~'

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

Guys I found the issue

I just tried by adding the qualifier name in employee service finally it solved my issue.

@Service("employeeService")

public class EmployeeServiceImpl implements EmployeeService{

}

How about asking the UIApplication singleton for its keyWindow, and from that UIWindow ask for the root view controller (its rootViewController property):

UIViewController root = [[[UIApplication sharedApplication] keyWindow] rootViewController];

Add commons-lang3-3.1.jar in your application build path. Use the below code snippet to trim the String array.

String array = {" String", "Tom Selleck "," Fish "};
array = StringUtils.stripAll(array);

$ cat foo.md
Key 1 | Value 1
Key 2 | Value 2

$ kramdown foo.md
<table>
  <tbody>
    <tr>
      <td>Key 1</td>
      <td>Value 1</td>
    </tr>
    <tr>
      <td>Key 2</td>
      <td>Value 2</td>
    </tr>
  </tbody>
</table>

check if a key is pressed, if yes, then do stuff

Consider 'select()', if this (reportedly Posix) function is available on your os.

'select()' uses 3 sets of bits, which you create using functions provided (see man select, FD_SET, etc). You probably only need create the input bits (for now)

from man page:

'select()' "allow a program to monitor multiple file descriptors, waiting until one or more of the file descriptors become "ready" for some class of I/O operation (e.g., input possible). A file descriptor is considered ready if it is possible to perform a corresponding I/O operation (e.g., read(2) without blocking...)"

When select is invoked:

a) the function looks at each fd identified in the sets, and if that fd state indicates you can do something (perhaps read, perhaps write), select will return and let you go do that ... 'all you got to do' is scan the bits, find the set bit, and take action on the fd associated with that bit.

The 1st set (passed into select) contains active input fd's (typically devices). Probably 1 bit in this set is all you will need. And with only 1 fd (i.e. an input from keyboard), 1 bit, this is all quite simple. With this return from select, you can 'do-stuff' (perhaps, after you have fetched the char).

b) the function also has a timeout, with which you identify how much time to await a change of the fd state. If the fd state does not change, the timeout will cause 'select()' to return with a 0. (i.e. no keyboard input) Your code can do something at this time, too, perhaps an output.

fyi - fd's are typically 0,1,2... Remembe that C uses 0 as STDIN, 1 and STDOUT.

Simple test set up: I open a terminal (separate from my console), and type the tty command in that terminal to find its id. The response is typically something like "/dev/pts/0", or 3, or 17...

Then I get an fd to use in 'select()' by using open:

// flag options are: O_RDONLY, O_WRONLY, or O_RDWR
int inFD = open( "/dev/pts/5", O_RDONLY ); 

It is useful to cout this value.

Here is a snippet to consider (from man select):

  fd_set rfds;
  struct timeval tv;
  int retval;

  /* Watch stdin (fd 0) to see when it has input. */
  FD_ZERO(&rfds);
  FD_SET(0, &rfds);

  /* Wait up to five seconds. */
  tv.tv_sec = 5;
  tv.tv_usec = 0;

  retval = select(1, &rfds, NULL, NULL, &tv);
  /* Don't rely on the value of tv now! */

  if (retval == -1)
      perror("select()");
  else if (retval)
      printf("Data is available now.\n");  // i.e. doStuff()
      /* FD_ISSET(0, &rfds) will be true. */
  else
      printf("No data within five seconds.\n"); // i.e. key not pressed

The ContentList's Set method will not get called when you change a value inside the collection, instead you should be looking out for the CollectionChanged event firing.

public class CollectionViewModel : ViewModelBase
{          
    public ObservableCollection<EntityViewModel> ContentList
    {
        get { return _contentList; }
    }

    public CollectionViewModel()
    {
         _contentList = new ObservableCollection<EntityViewModel>();
         _contentList.CollectionChanged += ContentCollectionChanged;
    }

    public void ContentCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        //This will get called when the collection is changed
    }
}

Okay, that's twice today I've been bitten by the MSDN documentation being wrong. In the link I gave you it says:

Occurs when an item is added, removed, changed, moved, or the entire list is refreshed.

But it actually doesn't fire when an item is changed. I guess you'll need a more bruteforce method then:

public class CollectionViewModel : ViewModelBase
{          
    public ObservableCollection<EntityViewModel> ContentList
    {
        get { return _contentList; }
    }

    public CollectionViewModel()
    {
         _contentList = new ObservableCollection<EntityViewModel>();
         _contentList.CollectionChanged += ContentCollectionChanged;
    }

    public void ContentCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        if (e.Action == NotifyCollectionChangedAction.Remove)
        {
            foreach(EntityViewModel item in e.OldItems)
            {
                //Removed items
                item.PropertyChanged -= EntityViewModelPropertyChanged;
            }
        }
        else if (e.Action == NotifyCollectionChangedAction.Add)
        {
            foreach(EntityViewModel item in e.NewItems)
            {
                //Added items
                item.PropertyChanged += EntityViewModelPropertyChanged;
            }     
        }       
    }

    public void EntityViewModelPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        //This will get called when the property of an object inside the collection changes
    }
}

If you are going to need this a lot you may want to subclass your own ObservableCollection that triggers the CollectionChanged event when a member triggers its PropertyChanged event automatically (like it says it should in the documentation...)

You could change the compiler settings to accept Java 6 syntax but generate Java 5 output (as I remember). And set the "Generated class files compatibility" a bit lower if needed by your runtime. Update: I checked Eclipse, but it complains if I set source compatibility to 1.6 and class compatibility to 1.5. If 1.6 is not allowed I usually manually comment out the offending @Override annotations in the source (which doesn't help your case).

Update2: If you do only manual build, you could write a small program which copies the original project into a new one, strips @Override annotations from the java sources and you just hit Clean project in Eclipse.

I have solved it by discarding my local amended commit and adding the new changes on top:

# Rewind to commit before conflicting
git reset --soft HEAD~1

# Pull the remote version
git pull

# Add the new commit on top
git add ...
git commit
git push

The answer has already been given, but I'd like to share an issue that I discovered lately with Java standard libraries. While they take great care now of replacing password strings with char[] everywhere (which of course is a good thing), other security-critical data seems to be overlooked when it comes to clearing it from memory.

I'm thinking of e.g. the PrivateKey class. Consider a scenario where you would load a private RSA key from a PKCS#12 file, using it to perform some operation. Now in this case, sniffing the password alone wouldn't help you much as long as physical access to the key file is properly restricted. As an attacker, you would be much better off if you obtained the key directly instead of the password. The desired information can be leaked manifold, core dumps, a debugger session or swap files are just some examples.

And as it turns out, there is nothing that lets you clear the private information of a PrivateKey from memory, because there's no API that lets you wipe the bytes that form the corresponding information.

This is a bad situation, as this paper describes how this circumstance could be potentially exploited.

The OpenSSL library for example overwrites critical memory sections before private keys are freed. Since Java is garbage-collected, we would need explicit methods to wipe and invalidate private information for Java keys, which are to be applied immediately after using the key.

If you declare an empty object literal and then assign values later on, then you can consider those values optional (may or may not be there), so just type them as optional with a question mark:

type User = {
    Username?: string;
    Email?: string;
}

JavaScript

var myObj = {
   id: "c001",
   name: "Hello Test"
}

Result(JSON)

{
   "id": "c001",
   "name": "Hello Test"
}

Whats wrong in this?

<form class="navbar-form navbar-right" method="post" action="login.php">
  <div class="form-group">
    <input type="email" name="email" class="form-control" placeholder="email">
    <input type="password" name="password" class="form-control" placeholder="password">
  </div>
  <input type="submit" name="submit" value="submit" class="btn btn-success">
</form>

login.php

if(isset($_POST['submit']) && !empty($_POST['submit'])) {
  // if (!logged_in()) 
  echo 'asodj';
}

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

While this will render in a web browser, beware that:
??Nesting an html button in an html a (or vice-versa) is not valid html ??. If you want to keep your html semantic to screen readers, use another approach.

Do wrapping in the reverse way and you get the original button with the Link attached. No CSS changes required.

 <Link to="/dashboard">
     <button type="button">
          Click Me!
     </button>
 </Link>

Here button is HTML button. It is also applicable to the components imported from third party libraries like Semantic-UI-React.

 import { Button } from 'semantic-ui-react'
 ... 
 <Link to="/dashboard">
     <Button style={myStyle}>
        <p>Click Me!</p>
     </Button>
 </Link>

use if var is null

AngularJS form elements look for the required attribute to perform validation functions. ng-required allows you to set the required attribute depending on a boolean test (for instance, only require field B - say, a student number - if the field A has a certain value - if you selected "student" as a choice)

As an example, <input required> and <input ng-required="true"> are essentially the same thing

If you are wondering why this is this way, (and not just make <input required="true"> or <input required="false">), it is due to the limitations of HTML - the required attribute has no associated value - its mere presence means (as per HTML standards) that the element is required - so angular needs a way to set/unset required value (required="false" would be invalid HTML)

You're looking for the @content directive:

@mixin placeholder {
  ::-webkit-input-placeholder {@content}
  :-moz-placeholder           {@content}
  ::-moz-placeholder          {@content}
  :-ms-input-placeholder      {@content}  
}

@include placeholder {
    font-style:italic;
    color: white;
    font-weight:100;
}

SASS Reference has more information, which can be found here: http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#mixin-content

As of Sass 3.4, this mixin can be written like so to work both nested and unnested:

@mixin optional-at-root($sel) {
  @at-root #{if(not &, $sel, selector-append(&, $sel))} {
    @content;
  }
}

@mixin placeholder {
  @include optional-at-root('::-webkit-input-placeholder') {
    @content;
  }

  @include optional-at-root(':-moz-placeholder') {
    @content;
  }

  @include optional-at-root('::-moz-placeholder') {
    @content;
  }

  @include optional-at-root(':-ms-input-placeholder') {
    @content;
  }
}

Usage:

.foo {
  @include placeholder {
    color: green;
  }
}

@include placeholder {
  color: red;
}

Output:

.foo::-webkit-input-placeholder {
  color: green;
}
.foo:-moz-placeholder {
  color: green;
}
.foo::-moz-placeholder {
  color: green;
}
.foo:-ms-input-placeholder {
  color: green;
}

::-webkit-input-placeholder {
  color: red;
}
:-moz-placeholder {
  color: red;
}
::-moz-placeholder {
  color: red;
}
:-ms-input-placeholder {
  color: red;
}

i think this solution is shorter and simpler than older answers. This is Js Code:

const navbar = document.querySelector('.nav-fixed');
window.onscroll = () => {
    if (window.scrollY > 300) {
        navbar.classList.add('nav-active');
    } else {
        navbar.classList.remove('nav-active');
    }
};

And my css:

header.nav-fixed {
    width: 100%;
    position: fixed;
    transition: 0.3s ease-in-out;
}

.nav-active {
    background-color:#fff;
    box-shadow: 5px -1px 12px -5px grey;
}

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

I ran into the same issue and found that the individual that created the worksheet had several columns locked. I removed the protection and everything worked as designed.

If you want to enable CORS for all routes, then just install flask_cors extension (pip3 install -U flask_cors) and wrap app like this: CORS(app).

That is enough to do it (I tested this with a POST request to upload an image, and it worked for me):

from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app) # This will enable CORS for all routes

Important note: if there is an error in your route, let us say you try to print a variable that does not exist, you will get a CORS error related message which, in fact, has nothing to do with CORS.

SELECT a AS current_a, COUNT(*) AS b,
   (SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d
   from t group by a order by b desc

Use the command

git clone --help

to see whether your git supports the command

git clone --branch tag_name

If not, just do the following:

git clone repo_url 
cd repo
git checkout tag_name

you can't access your drawables via a path, so if you want a human readable interface with your drawables that you can build programatically.

declare a HashMap somewhere in your class:

private static HashMap<String, Integer> images = null;

//Then initialize it in your constructor:

public myClass() {
  if (images == null) {
    images = new HashMap<String, Integer>();
    images.put("Human1Arm", R.drawable.human_one_arm);
    // for all your images - don't worry, this is really fast and will only happen once
  }
}

Now for access -

String drawable = "wrench";
// fill in this value however you want, but in the end you want Human1Arm etc
// access is fast and easy:
Bitmap wrench = BitmapFactory.decodeResource(getResources(), images.get(drawable));
canvas.drawColor(Color .BLACK);
Log.d("OLOLOLO",Integer.toString(wrench.getHeight()));
canvas.drawBitmap(wrench, left, top, null);

Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

Here,

this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field

oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.

np.convolve() takes one dimension array. You need to check the input and convert it into 1D.

You can use the np.ravel(), to convert the array to one dimension.

In general, you want to go from XML to regular objects of your language (since there are usually reasonable tools to do this, and it's the harder conversion). And then from Plain Old Object produce JSON -- there are tools for this, too, and it's a quite simple serialization (since JSON is "Object Notation", natural fit for serializing objects). I assume Python has its set of tools.

Just import Android.app,then you can use: <br/>Application.getProcessName()<br/>

Get the current Application Process Name without context, view, or activity.

if you are using Maven 2.0.8+, then it will be very simple, run mvndebug from the console, and connect to it via Remote Debug Java Application with port 8000.

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

This is the configuration file for Maven. It can be specified at two levels:

1. User Level. This settings.xml file provides configuration for a single user, and is normally provided in ${user.home}/.m2/settings.xml.

             NOTE: This location can be overridden with the CLI option:
   
             -s /path/to/user/settings.xml
   

2. Global Level. This settings.xml file provides configuration for all Maven users on a machine (assuming they're all using the same Maven installation). It's normally provided in ${maven.home}/conf/settings.xml.

             NOTE: This location can be overridden with the CLI option:
   
             -gs /path/to/global/settings.xml
   

jspdf does not work with css but it can work along with html2canvas. You can use jspdf along with html2canvas.

include these two files in script on your page :

<script type="text/javascript" src="html2canvas.js"></script>
  <script type="text/javascript" src="jspdf.min.js"></script>
  <script type="text/javascript">
  function genPDF()
  {
   html2canvas(document.body,{
   onrendered:function(canvas){

   var img=canvas.toDataURL("image/png");
   var doc = new jsPDF();
   doc.addImage(img,'JPEG',20,20);
   doc.save('test.pdf');
   }

   });

  }
  </script>

You need to download script files such as https://github.com/niklasvh/html2canvas/releases https://cdnjs.com/libraries/jspdf

make clickable button on page so that it will generate pdf and it will be seen same as that of original html page.

<a href="javascript:genPDF()">Download PDF</a>  

It will work perfectly.

By specifying the @JoinColumn on both models you don't have a two way relationship. You have two one way relationships, and a very confusing mapping of it at that. You're telling both models that they "own" the IDAIRLINE column. Really only one of them actually should! The 'normal' thing is to take the @JoinColumn off of the @OneToMany side entirely, and instead add mappedBy to the @OneToMany.

@OneToMany(cascade = CascadeType.ALL, mappedBy="airline")
public Set<AirlineFlight> getAirlineFlights() {
    return airlineFlights;
}

That tells Hibernate "Go look over on the bean property named 'airline' on the thing I have a collection of to find the configuration."

pgAdmin has GUI for data import since 1.16. You have to create your table first and then you can import data easily - just right-click on the table name and click on Import.

The bug is probably somewhere else in your code, because it should work fine:

>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True

Or with tuples:

>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True

My 'hack' solution is

   <div class="col-sm-5">
        <laps
            [lapsData]="rawLapsData"
            [selectedTps]="selectedTps"
            (lapsHandler)="lapsHandler($event)">
        </laps>
    </div>
    <map
        [lapsData]="rawLapsData"
        [selectedTps]="selectedTps"   // <--------
        class="col-sm-7">
    </map>

selectedTps changes at the same time as rawLapsData and that gives map another chance to detect the change through a simpler object primitive type. It is NOT elegant, but it works.

Whatever you do to secure your secret keys is not going to be a real solution. If developer can decompile the application there is no way to secure the key, hiding the key is just security by obscurity and so is code obfuscation. Problem with securing a secret key is that in order to secure it you have to use another key and that key needs to also be secured. Think of a key hidden in a box that is locked with a key. You place a box inside a room and lock the room. You are left with another key to secure. And that key is still going to be hardcoded inside your application.

So unless the user enters a PIN or a phrase there is no way to hide the key. But to do that you would have to have a scheme for managing PINs happening out of band, which means through a different channel. Certainly not practical for securing keys for services like Google APIs.

IIS will create it again AFAIK.

No. The only you can do is to add content (and not an element) using :before or :after pseudo-element.

From Zvon.org XSLT Reference:

Hope this helps.

'&' performs both tests, while '&&' only performs the 2nd test if the first is also true. This is known as shortcircuiting and may be considered as an optimization. This is especially useful in guarding against nullness(NullPointerException).

if( x != null && x.equals("*BINGO*") {
  then do something with x...
}

MSTest (v2) now has an Assert.ThrowsException function which can be used like this:

Assert.ThrowsException<System.FormatException>(() =>
            {
                Story actual = PersonalSite.Services.Content.ExtractHeader(String.Empty);
            }); 

You can install it with nuget: Install-Package MSTest.TestFramework

You can do this programmatically with the below snippet. That provides white letters with black background:

textView.setTextColor(Color.WHITE);            
textView.setShadowLayer(1.6f,1.5f,1.3f,Color.BLACK);

The parameters of the method are radius,dx,dy,color. You can change them for you specific needs.

I hope I will help someone that creates TextView programmatically and not having it inside xml.

Cheers to the stackOverflow community!
