Check again. Use debugger if must. My guess is that for some item in userResponseDetails this query finds no elements:

.Where(y => y.ResponseId.Equals(item.ResponseId))

so you can't call

.First()

on it. Maybe try

.FirstOrDefault()

if it solves the issue.

Do NOT return NULL value! This is purely so that you can see and diagnose where problem is. Handle these cases properly.

Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.

Normally it happens when the target is null. So better check the invoke target first then do the linq query.

I am using web service in my tool, where those service fetch the stored procedure. while more number of client tool fetches the web service, this problem arises. I have fixed by specifying the Synchronized attribute for those function fetches the stored procedure. now it is working fine, the error never showed up in my tool.

 [MethodImpl(MethodImplOptions.Synchronized)]
 public static List<t> MyDBFunction(string parameter1)
  {
  }

This attribute allows to process one request at a time. so this solves the Issue.

I had a similar situation with the 'An error occurred while executing the command definition' error. I had some views which were grabbing from another db which used current user security. The second db did not allow the login for the user of the first db causing this issue to occur. I added the db login to the server it was trying to get to from the original server and this fixed the issue. Check your views and see if there are any linked dbs which have different security than the db you are logging onto originally.

If anyone is having this exception and is building the query using Scala multi-line strings:

Looks like there is a problem with some JPA drivers in this situation. I'm not sure what is the character Scala uses for LINE END, but when you have a parameter right at the end of the line, the LINE END character seems to be attached to the parameter and so when the driver parses the query, this error comes up. A simple work around is to leave an empty space right after the param at the end:

SELECT * FROM some_table a
WHERE a.col = ?param
AND a.col2 = ?param2

So, just make sure to leave an empty space after param (and param2, if you have a line break there).

step-1) On Notepad++ Toolbar:

Plugins -> Plugin Manager -> Show Plugin Manager -> Available . Then select the Explorer. And click Install.

(Note: As in above comments some people like SherloXplorer. Pls, note that this requires .Net v2 )

step-2) Again on Notepad++ Toolbar:

Explorer->Explorer

Now you can view files with tree view.

Update: After adding Explorer, right click to edit a file in Notepad++ may stop working. To make it work again, restart Notepad++ afresh.

Editor's note: the approach below has serious security implications and, depending upon the version of jQuery you are using, may expose your users to XSS attacks. For more detail, see the discussion of the possible attack in the comments on this answer or this explanation on Security Stack Exchange.

You can use the location.hash property to grab the hash of the current page:

var hash = window.location.hash;
$('ul'+hash+':first').show();

Note that this property already contains the # symbol at the beginning.

Actually you don't need the :first pseudo-selector since you are using the ID selector, is assumed that IDs are unique within the DOM.

In case you want to get the hash from an URL string, you can use the String.substring method:

var url = "http://example.com/file.htm#foo";
var hash = url.substring(url.indexOf('#')); // '#foo'

Advice: Be aware that the user can change the hash as he wants, injecting anything to your selector, you should check the hash before using it.

var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");

function removeColumn(#){
// remove column #
}

Yet another approach - just set a flag on an element signaling which type of event should be handled:

function setRangeValueChangeHandler(rangeElement, handler) {
    rangeElement.oninput = (event) => {
        handler(event);
        // Save flag that we are using onInput in current browser
        event.target.onInputHasBeenCalled = true;
    };

    rangeElement.onchange = (event) => {
        // Call only if we are not using onInput in current browser
        if (!event.target.onInputHasBeenCalled) {
            handler(event);
        }
    };
}

well, as an easier alternative and shorter, you could do this too!!

var fd = new FormData();

var file_data = object.get(0).files[i];
var other_data = $('form').serialize(); //page_id=&category_id=15&method=upload&required%5Bcategory_id%5D=Category+ID

fd.append("file", file_data);

$.ajax({
    url: 'add.php?'+ other_data,  //<== just add it to the end of url ***
    data: fd,
    contentType: false,
    processData: false,
    type: 'POST',
    success: function(data){
        alert(data);
    }
});

If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-

[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb

Mysql would then open this file for each user account read the credentials and open the selected database.

Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.

As Eik says, UIStackView and UIScrollView play together nicely, see here.

The key is that the UIStackView handles the variable height/width for different contents and the UIScrollView then does its job well of scrolling/bouncing that content:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    scrollView.contentSize = CGSize(width: stackView.frame.width, height: stackView.frame.height)       
}

Works in SQL server

Declare @GivenDate datetime
SET @GivenDate = GETDATE()

Select DATEADD(MM,DATEDIFF(MM, 0, @GivenDate),0) --First day of the month 

Select DATEADD(MM,DATEDIFF(MM, -1, @GivenDate),-1) --Last day of the month

The summary is that I found ECMerge to be a great, though commercial product. http://www.elliecomputing.com/products/merge_overview.asp

I also agree with MrTelly that Ultracompare is very good. One nice feature is that it will compare RTF and Word docs, which is handy when you end up programming in word with the sales guys and they don't manage their docs correctly.

Persistence Context is an environment or cache where entity instances(which are capable of holding data and thereby having the ability to be persisted in a database) are managed by Entity Manager.It syncs the entity with database.All objects having @Entity annotation are capable of being persisted. @Entity is nothing but a class which helps us create objects in order to communicate with the database.And the way the objects communicate is using methods.And who supplies those methods is the Entity Manager.

EOF is -1 because that's how it's defined. The name is provided by the standard library headers that you #include. They make it equal to -1 because it has to be something that can't be mistaken for an actual byte read by getchar(). getchar() reports the values of actual bytes using positive number (0 up to 255 inclusive), so -1 works fine for this.

The != operator means "not equal". 0 stands for false, and anything else stands for true. So what happens is, we call the getchar() function, and compare the result to -1 (EOF). If the result was not equal to EOF, then the result is true, because things that are not equal are not equal. If the result was equal to EOF, then the result is false, because things that are equal are not (not equal).

The call to getchar() returns EOF when you reach the "end of file". As far as C is concerned, the 'standard input' (the data you are giving to your program by typing in the command window) is just like a file. Of course, you can always type more, so you need an explicit way to say "I'm done". On Windows systems, this is control-Z. On Unix systems, this is control-D.

The example in the book is not "wrong". It depends on what you actually want to do. Reading until EOF means that you read everything, until the user says "I'm done", and then you can't read any more. Reading until '\n' means that you read a line of input. Reading until '\0' is a bad idea if you expect the user to type the input, because it is either hard or impossible to produce this byte with a keyboard at the command prompt :)

I have also been through this problem,

First i tried setting my password of root to blank using command :

SET PASSWORD FOR root@localhost=PASSWORD('');

But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.

SET PASSWORD FOR [email protected]=PASSWORD('');

Just replace localhost with 127.0.0.1 and you are done .

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

From a Powershell script, you can try this. I only had a single version of the assembly in the GAC so this worked just fine.

cd "c:\Windows\Microsoft.NET\assembly\GAC_MSIL\"
Get-ChildItem assemblypath -Recurse -Include *.dll |  Copy-Item -Destination "c:\folder to copy to"

where the assembly path can use wildcards.

In Bootstrap 3 they do not have separate classes for different styles of labels.

http://getbootstrap.com/components/

However, you can customize bootstrap classes that way. In your css file

.lb-sm {
  font-size: 12px;
}

.lb-md {
  font-size: 16px;
}

.lb-lg {
  font-size: 20px;
}

Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label

<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>

They might add size classes for labels in future Bootstrap versions.

Use the static method Guid.NewGuid() instead of calling the default constructor.

var responseObject = proxy.CallService(new RequestObject
{
    Data = "misc. data",
    Guid = Guid.NewGuid()
});

This is one of those instances where jquery actually makes it more complicated than what the DOM already provides.

let { top, bottom, height, width, //etc } = $('#bottom')[0].getBoundingClientRect();
return top;

This is what I did:

1. Change project and solution name in Visual Studio
2. Close the project and open the folder containing the project (The Visual studio solution name is already changed).
3. Change the old project folder names to the new project name
4. Open the .sln file and the change the project folder names manually from old to new folder names.
5. Save the .sln file in the text editor
6. Open the project again with Visual Studio and the solution is ready to modify

in python the operators should be in quotes: db.ProductData.update({'fromAddress':'http://localhost:7000/'}, {"$set": {'fromAddress': 'http://localhost:5000/'}},{"multi": True})

Create custom helpers’ directory: First create Helpers directory in app directory. Create hlper class definition: Let’s now create a simple helper function that will concatenate two strings. Create a new file MyFuncs.php in /app/Helpers/MyFuncs.php Add the following code

<?php

namespace App\Helpers;

class MyFuncs {

    public static function full_name($first_name,$last_name) {
        return $first_name . ', '. $last_name;   
    }
}

namespace App\Helpers; defines the Helpers namespace under App namespace. class MyFuncs {…} defines the helper class MyFuncs. public static function full_name($first_name,$last_name) {…} defines a static function that accepts two string parameters and returns a concatenated string

Helpers service provide class

Service providers are used to auto load classes. We will need to define a service provider that will load all of our helper classes in /app/Helpers directory.

Run the following artisan command:

php artisan make:provider HelperServiceProvider

The file will be created in /app/Providers/HelperServiceProvider.php

Open /app/Providers/HelperServiceProvider.php

Add the following code:

<?php 

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class HelperServiceProvider extends ServiceProvider {

   /**
    * Bootstrap the application services.
    *
    * @return void
    */
   public function boot()
   {
      //
   }

   /**
    * Register the application services.
    *
    * @return void
    */
   public function register()
   {
        foreach (glob(app_path().'/Helpers/*.php') as $filename){
            require_once($filename);
        }
   }
}

HERE,

namespace App\Providers; defines the namespace provider
use Illuminate\Support\ServiceProvider; imports the ServiceProvider class namespace
class HelperServiceProvider extends ServiceProvider {…} defines a class HelperServiceProvider that extends the ServiceProvider class
public function boot(){…} bootstraps the application service
public function register(){…} is the function that loads the helpers
foreach (glob(app_path().'/Helpers/*.php') as $filename){…} loops through all the files in /app/Helpers directory and loads them.

We now need to register the HelperServiceProvider and create an alias for our helpers.

Open /config/app.php file

Locate the providers array variable

Add the following line

App\Providers\HelperServiceProvider::class,

Locate the aliases array variable

Add the following line

'MyFuncs' => App\Helpers\MyFuncs::class,

Save the changes Using our custom helper

We will create a route that will call our custom helper function Open /app/routes.php

Add the following route definition

Route::get('/func', function () {
    return MyFuncs::full_name("John","Doe");
});

HERE,

return MyFuncs::full_name("John","Doe"); calls the static function full_name in MyFuncs class

I was able to handle this in Spring 2 as following

 private boolean isInPath(ServletRequest request) {
   String PATH_TO_VALIDATE = "/path/";
   String path = ((HttpServletRequest) request).getRequestURI();
   return path != null && path.toLowerCase().contains(PATH_TO_VALIDATE);
}

You may try this code,

<textarea name="textarea" cols="70" rows="2" class="searchBox" id="textarea" onfocus="if(this.value == 'Please describe why') this.value='';" onblur="if(this.value == '') this.value='Please describe why';">Please describe why</textarea>

The approach

for item in all:
    item.start()

is simple, easy, readable, and concise. This is the main approach Python provides for this operation. You can certainly encapsulate it in a function if that helps something. Defining a special function for this for general use is likely to be less clear than just writing out the for loop.

On windows 10 (client) you can also script this using

Enable-WindowsOptionalFeature -Online -NoRestart -FeatureName WCF-HTTP-Activation45 -All

Note that this is a different command from the server skus

Sets versus list comprehension benchmark on Python 3.8

(adding up to Moinuddin Quadri's benchmarks)

tldr: Use Arkku's set solution, it's even faster than promised in comparison!

Checking existing files against a list

In my example I found it to be 40 times (!) faster to use Arkku's set solution than the pythonic list comprehension for a real world application of checking existing filenames against a list.

List comprehension:

%%time
import glob
existing = [int(os.path.basename(x).split(".")[0]) for x in glob.glob("*.txt")]
wanted = list(range(1, 100000))
[i for i in wanted if i not in existing]

Wall time: 28.2 s

Sets

%%time
import glob
existing = [int(os.path.basename(x).split(".")[0]) for x in glob.glob("*.txt")]
wanted = list(range(1, 100000))
set(wanted) - set(existing)

Wall time: 689 ms

I think the new preferred way might be to use IDataErrorInfo

Read more here

Starting from C# 2.0, you can use the nullable generic type Nullable, and in C# there is a shorthand notation the type followed by ?

e.g.

private void Example(int? arg1, int? arg2)
{
    if(arg1 == null)
    {
        //do something
    }
    if(arg2 == null)
    {
        //do something else
    }
}

None of the above solutions worked for me on Windows 8

But the following command works fine

SHIFT + Q

    public static void PrintFileToDefaultPrinter(string FilePath)
    {
        try
        {
            var file = File.ReadAllBytes(FilePath);
            var printQueue = LocalPrintServer.GetDefaultPrintQueue();

            using (var job = printQueue.AddJob())
            using (var stream = job.JobStream)
            {
                stream.Write(file, 0, file.Length);
            }
        }
        catch (Exception)
        {

            throw;
        }
    }

Try git config core.fileMode false

From the git config man page:

core.fileMode

If false, the executable bit differences between the index and the working copy are ignored; useful on broken filesystems like FAT. See git-update-index(1).

The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if appropriate when the repository is created.

According to catalina.sh customizations should always go into your own setenv.sh (or setenv.bat respectively) eg:

CATALINA_OPTS='-Xms512m -Xmx1024m'

My guess is that setenv.bat will also be called when starting a service.I might be wrong, though, since I'm not a windows user.

Contacts.add(objt.Data(name, address, contact));

This is not a perfect way to call a constructor. The constructor is called at the time of object creation automatically. If there is no constructor java class creates its own constructor.

The correct way is:

// object creation. 
Data object1 = new Data(name, address, contact);      

// adding Data object to ArrayList object Contacts.
Contacts.add(object1);                              

I’m tempted to say that both are bad practices.

The use of onclick or javascript: should be dismissed in favor of listening to events from outside scripts, allowing for a better separation between markup and logic and thus leading to less repeated code.

Note also that external scripts get cached by the browser.

Have a look at this answer.

Some good ways of implementing cross-browser event listeners here.

The stash command will stash any changes you have made since your last commit. In your case there is no reason to stash if you are gonna continue working on it the next day. I would only use stash to undo changes that you don't want to commit.

If you select a cell in an already selected range, it will not work. But, Selecting a range outside the original selection will clear the original selection.

'* The original selection *' ActiveSheet.range("A1:K10").Select

'* New Selections *' Activesheet.Range("L1").Select

'* Then *' Activesheet.Range("A1").Select

The important needs to be inside the ;

td.rule2 div {     background-color: #ffff00 !important; } 

in fact i believe this should override it

td.rule2 { background-color: #ffff00 !important; } 

If you want a dictionary you can import from a file by name, and also that adds entries that are nicely sorted, and contains strings you want to preserve, you can try this:

data = {'A': 'a', 'B': 'b', }

with open('file.py','w') as file:
    file.write("dictionary_name = { \n")
    for k in sorted (data.keys()):
        file.write("'%s':'%s', \n" % (k, data[k]))
    file.write("}")

Then to import:

from file import dictionary_name

I would take a look at Spring's abstract test classes and mock objects which are talked about here. They provide a powerful way of auto-wiring your Spring managed objects making unit and integration testing easier.

Hi solution mentioned by Damien McGivern, Works on IIS6 only,

It does not work on IIS7 and ASP.NET Development Server. I get page displaying "404 - File or directory not found."

Any ideas?

EDIT:

Got it... This solution still doesn't work on ASP.NET Development Server, but I got the reason why it was not working on IIS7 in my case.

The reason is IIS7 has a built-in request scanning which imposes an upload file cap which defaults to 30000000 bytes (which is slightly less that 30MB).

And I was trying to upload file of size 100 MB to test the solution mentioned by Damien McGivern (with maxRequestLength="10240" i.e. 10MB in web.config). Now, If I upload the file of size > 10MB and < 30 MB then the page is redirected to the specified error page. But if the file size is > 30MB then it show the ugly built-in error page displaying "404 - File or directory not found."

So, to avoid this, you have to increase the max. allowed request content length for your website in IIS7. That can be done using following command,

appcmd set config "SiteName" -section:requestFiltering -requestLimits.maxAllowedContentLength:209715200 -commitpath:apphost

I have set the max. content length to 200MB.

After doing this setting, the page is succssfully redirected to my error page when I try to upload file of 100MB

Refer, http://weblogs.asp.net/jgalloway/archive/2008/01/08/large-file-uploads-in-asp-net.aspx for more details.

    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [UIColor clearColor],UITextAttributeTextColor,
                                nil];

    [[UIBarButtonItem appearance] setTitleTextAttributes:attributes
                                                forState:UIControlStateNormal];

I was having a same problem and I did it this way.

--EDIT--

this is a solution when you really want to remove title text of all UIBarbuttonItem. If you only want to remove the title of the back bar button item, there is no one simple convenient solution. In my case, since I only have few UIBarButtonItems that need to show title text I just changed those specific buttons' titleTextAttributes. If you want to be more specific use the code below, which will only change navigation bar buttons:

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [UIColor clearColor],UITextAttributeTextColor,
                                nil];

[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:attributes
                                                forState:UIControlStateNormal];

1. You generate it once, and again when you'd like to change the version of Gradle you use in the project. There's no need to generate is so often. Here are the docs. Just add wrapper task to build.gradle file and run this task to get the wrapper structure.

   Mind that you need to have Gradle installed to generate a wrapper. Great tool for managing g-ecosystem artifacts is SDKMAN!. To generate a gradle wrapper, add the following piece of code to build.gradle file:

   task wrapper(type: Wrapper) {
      gradleVersion = '2.0' //version required
   }
   

   and run:

   gradle wrapper
   

   task. Add the resulting files to SCM (e.g. git) and from now all developers will have the same version of Gradle when using Gradle Wrapper.

   With Gradle 2.4 (or higher) you can set up a wrapper without adding a dedicated task:

   gradle wrapper --gradle-version 2.3
   

   or

   gradle wrapper --gradle-distribution-url https://myEnterpriseRepository:7070/gradle/distributions/gradle-2.3-bin.zip
   

   All the details can be found here

From Gradle 3.1 --distribution-type option can be also used. The options are binary and all and bin. all additionally contains source code and documentation. all is also better when IDE is used, so the editor works better. Drawback is the build may last longer (need to download more data, pointless on CI server) and it will take more space.

2. These are Gradle Wrapper files. You need to generate them once (for a particular version) and add to version control. If you need to change the version of Gradle Wrapper, change the version in build.gradle see (1.) and regenerate the files.

3. Give a detailed example. Such file may have multiple purposes: multi-module project, responsibility separation, slightly modified script, etc.

4. settings.gradle is responsible rather for structure of the project (modules, names, etc), while, gradle.properties is used for project's and Gradle's external details (version, command line arguments -XX, properties etc.)

Try the code below and.....

1 - change the name of the MENU as in my sample the menuitem was called 'Form7ToolStripMenuItem_Click'

2 - make SURE to paste it into an MDIFORM and not just a basic FORM

Then let me know if the CHILD form still shows OUTSIDE the parent form

Private Sub Form7ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form7ToolStripMenuItem.Click

    Dim NewForm As System.Windows.Forms.Form
    NewForm = New System.Windows.Forms.Form
    'USE THE NEXT LINE - to add an existing CUSTOM form you already have
    'NewForm = Form7                         
    NewForm.Width = 400
    NewForm.Height = 250
    NewForm.MdiParent = Me
    NewForm.Text = "CAPTION"
    NewForm.Show()
    DockChildForm(NewForm, "left")          'dock left
    'DockChildForm(NewForm, "right")         'dock right
    'DockChildForm(NewForm, "top")           'dock top
    'DockChildForm(NewForm, "bottom")        'doc bottom
    'DockChildForm(NewForm, "full")          'fill the client area (maximise the child INSIDE the parent)
    'DockChildForm(NewForm, "Anything-Else") 'center the form

End Sub

Private Sub DockChildForm(ByRef Form2Dock As Form, ByVal Position As String)

    Dim XYpoint As Point
    Select Case Position
        Case "left"
            Form2Dock.Dock = DockStyle.Left
        Case "top"
            Form2Dock.Dock = DockStyle.Top
        Case "right"
            Form2Dock.Dock = DockStyle.Right
        Case "bottom"
            Form2Dock.Dock = DockStyle.Bottom
        Case "full"
            Form2Dock.Dock = DockStyle.Fill
        Case Else
            XYpoint = New Point
            XYpoint.X = ((Me.ClientSize.Width - Form2Dock.Width) / 2)
            XYpoint.Y = ((Me.ClientSize.Height - Form2Dock.Height) / 2)
            Form2Dock.Location = XYpoint
    End Select
End Sub

There is no error when I use your code,

but I am calling the hasLetter method like this:

I've used MongoDB extensively (for the past 6 months), building a hierarchical data management system, and I can vouch for both the ease of setup (install it, run it, use it!) and the speed. As long as you think about indexes carefully, it can absolutely scream along, speed-wise.

I gather that Cassandra, due to its use with large-scale projects like Twitter, has better scaling functionality, although the MongoDB team is working on parity there. I should point out that I've not used Cassandra beyond the trial-run stage, so I can't speak for the detail.

The real swinger for me, when we were assessing NoSQL databases, was the querying - Cassandra is basically just a giant key/value store, and querying is a bit fiddly (at least compared to MongoDB), so for performance you'd have to duplicate quite a lot of data as a sort of manual index. MongoDB, on the other hand, uses a "query by example" model.

For example, say you've got a Collection (MongoDB parlance for the equivalent to a RDMS table) containing Users. MongoDB stores records as Documents, which are basically binary JSON objects. e.g:

{
   FirstName: "John",
   LastName: "Smith",
   Email: "[email protected]",
   Groups: ["Admin", "User", "SuperUser"]
}

If you wanted to find all of the users called Smith who have Admin rights, you'd just create a new document (at the admin console using Javascript, or in production using the language of your choice):

{
   LastName: "Smith",
   Groups: "Admin"
}

...and then run the query. That's it. There are added operators for comparisons, RegEx filtering etc, but it's all pretty simple, and the Wiki-based documentation is pretty good.

Old question but just had that problem /dumb jira having problems with java 10/ and didn't find a simple answer here so just gonna leave it:

$ /usr/libexec/java_home -V shows the versions installed and their locations so you can simply remove /Library/Java/JavaVirtualMachines/<the_version_you_want_to_remove>. Voila

This works for me:

Console.OutputEncoding = System.Text.Encoding.Default;

To display some of the symbols, it's required to set Command Prompt's font to Lucida Console:

1. Open Command Prompt;

2. Right click on the top bar of the Command Prompt;

3. Click Properties;

4. If the font is set to Raster Fonts, change it to Lucida Console.

Please add the shared dependency having jackson databind package . Hope this will clear the issue.

  <dependency>

It is always dependent on where is your html file that refers to the path of the static resource (in this case the image).

Example A:

src
|__assests
   |__images
      |__myimage.png
|__yourmodule
   |__yourpage.html

As you can see, yourpage.html is one folder away from the root (src folder), for this reason it needs one amount of ../ to go back to the root then you can walk to the image from root:

<img class="img-responsive" src="../assests/images/myimage.png">

Example B:

src
|__assests
   |__images
      |__myimage.png
|__yourmodule
   |__yoursubmodule
      |__yourpage.html

Here you have to go u in the tree by 2 folders:

<img class="img-responsive" src="../../assests/images/myimage.png">

I use FLTK because Qt is not free. I don't choose wxWidgets, because my first test with a simple Hello, World! program produced an executable of 24 MB, FLTK 0.8 MB...

I noticed the exact same issue when logging onto servers running Red Hat from an OSX Lion machine.

Try adding or editing the ~/.profile file for it to correctly export your locale settings upon initiating a new session.

export LC_ALL=en_US.UTF-8  
export LANG=en_US.UTF-8

These two lines added to the file should suffice to set the locale [replace en_US for your desired locale, and check beforehand that it is indeed installed on your system (locale -a)].

After that, you can start a new session and check using locale:

$ locale

The following should be the output:

LANG="en_US.UTF-8"  
LC_COLLATE="en_US.UTF-8"  
LC_CTYPE="en_US.UTF-8"  
LC_MESSAGES="en_US.UTF-8"  
LC_MONETARY="en_US.UTF-8"  
LC_NUMERIC="en_US.UTF-8"  
LC_TIME="en_US.UTF-8"  
LC_ALL="en_US.UTF-8"  

I just want to add some remarks to the great answer by Fredrik.

The Java Language Specification in Section 4.3.1 states

An object is a class instance or an array.

So array has indeed a very special role in Java. I do wonder why.

One could argue that current implementation array is/was important for a better performance. But than it is an internal structure, which should not be exposed.

They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

I agree with Fredrik, that a smart compiler optimazation would have been the better choice. This would also solve the problem, that even if you use a property for arrays, you have not solved the problem for strings and other (immutable) collection types, because, e.g., string is based on a char array as you can see on the class definition of String:

public final class String implements java.io.Serializable, Comparable<String>, CharSequence {           
    private final char value[]; // ...

And I do not agree with that it would be even more confusing, because array does inherit all methods from java.lang.Object.

As an engineer I really do not like the answer "Because it has been always this way." and wished there would be a better answer. But in this case it seems to be.

tl;dr

In my opinion, it is a design flaw of Java and should not have implemented this way.

Here is the C++ code:

bool FindSumZero(int a[], int n, int& x, int& y, int& z)
{
    if (n < 3)
        return false;

    sort(a, a+n);

    for (int i = 0; i < n-2; ++i)
    {
        int j = i+1;
        int k = n-1;

        while (k >= j)
        {
            int s = a[i]+a[j]+a[k];

            if (s == 0 && i != j && j != k && k != i)
            {
                x = a[i], y = a[j], z = a[k];
                return true;
            }

            if (s > 0)
                --k;
            else
                ++j;
        }
    }

    return false;
}

    select v.SQL_TEXT,
           v.PARSING_SCHEMA_NAME,
           v.FIRST_LOAD_TIME,
           v.DISK_READS,
           v.ROWS_PROCESSED,
           v.ELAPSED_TIME,
           v.service
      from v$sql v
where to_date(v.FIRST_LOAD_TIME,'YYYY-MM-DD hh24:mi:ss')>ADD_MONTHS(trunc(sysdate,'MM'),-2)

where clause is optional. You can sort the results according to FIRST_LOAD_TIME and find the records up to 2 months ago.

You can use also "void*" (void pointer) to send an address to the function.

typedef struct pstring_t {
    char * chars;
    int(*length)(void*);
} PString;

int length(void* self) {
    return strlen(((PString*)self)->chars);
}

PString initializeString() {
    PString str;
    str.length = &length;
    return str;
}

int main()
{
    PString p = initializeString();

    p.chars = "Hello";

    printf("Length: %i\n", p.length(&p));

    return 0;
}

Output:

Length: 5

for l in list1:
    val = 50 - l[0] + l[1] - l[2]
    print "val:", val

Loop through list and do operation on the sublist as you wanted.

I was looking for solution for exactly the same problem. To remove all classes starting with prefix "fontid_" After reading this article I wrote a small plugin which I'm using now.

(function ($) {
        $.fn.removePrefixedClasses = function (prefix) {
            var classNames = $(this).attr('class').split(' '),
                className,
                newClassNames = [],
                i;
            //loop class names
            for(i = 0; i < classNames.length; i++) {
                className = classNames[i];
                // if prefix not found at the beggining of class name
                if(className.indexOf(prefix) !== 0) {
                    newClassNames.push(className);
                    continue;
                }
            }
            // write new list excluding filtered classNames
            $(this).attr('class', newClassNames.join(' '));
        };
    }(fQuery));

Usage:

$('#elementId').removePrefixedClasses('prefix-of-classes_');

You have encoding problem with your sourcecode file. It is maybe ISO-8859-1 encoded, but the compiler was set to use UTF-8. This will results in errors when using characters, which will not have the same bytes representation in UTF-8 and ISO-8859-1. This will happen to all characters which are not part of ASCII, for example ¬ NOT SIGN.

You can simulate this with the following program. It just uses your line of source code and generates a ISO-8859-1 byte array and decode this "wrong" with UTF-8 encoding. You can see at which position the line gets corrupted. I added 2 spaces at your source code to fit position 74 to fit this to ¬ NOT SIGN, which is the only character, which will generate different bytes in ISO-8859-1 encoding and UTF-8 encoding. I guess this will match indentation with the real source file.

 String reg = "      String reg = \"^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[~#;:?/@&!\"'%*=¬.,-])(?=[^\\s]+$).{8,24}$\";";
 String corrupt=new String(reg.getBytes("ISO-8859-1"),"UTF-8");
 System.out.println(corrupt+": "+corrupt.charAt(74));
 System.out.println(reg+": "+reg.charAt(74));     

which results in the following output (messed up because of markup):

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=?.,-])(?=[^\s]+$).{8,24}$";: ?

String reg = "^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[~#;:?/@&!"'%*=¬.,-])(?=[^\s]+$).{8,24}$";: ¬

To fix this, save the source files with UTF-8 encoding.

This answer is for Mongo 3.2.1 Reference

Terminal 1:

$ mongod --auth

Terminal 2:

db.createUser({user:"admin_name", pwd:"1234",roles:["readWrite","dbAdmin"]})

if you want to add without roles (optional):

db.createUser({user:"admin_name", pwd:"1234", roles:[]})

to check if authenticated or not:

db.auth("admin_name", "1234")

it should give you:

else :

Error: Authentication failed.
0

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
    FROM DBA_SEGMENTS DS

    GROUP BY DS.TABLESPACE_NAME, SEGMENT_NAME;

The DOM methods getElementById(), nextSibling(), childNodes[n], parentNode() and so on return null (defined but having no value) when the call does not return a node object.

The property is defined, but the object it refers to does not exist.

This is one of the few times you may not want to test for equality-

if(x!==undefined) will be true for a null value

but if(x!= undefined) will be true (only) for values that are not either undefined or null.

You could do something like this, based on the ascii values of the characters:

char[26] alphabet;

for(int i = 0; i <26; i++)
{
     alphabet[i] = (char)(i+65); //65 is the offset for capital A in the ascaii table
}

(See the table here.) You are just casting from the int value of the character to the character value - but, that only works for ascii characters not different languages etc.

EDIT: As suggested by Mehrdad in the comment to a similar solution, it's better to do this:

alphabet[i] = (char)(i+(int)('A'));

This casts the A character to it's int value and then increments based on this, so it's not hardcoded.

In my case, I passed an async lambda to Console.CancelKeyPress, which won't work.

Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.

The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback) function from fs module:

var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
  if (err) {
    // append failed
  } else {
    // done
  }
})

But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options]) function instead:

var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
  flags: 'a' // 'a' means appending (old data will be preserved)
})

logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again

Node will keep appending new data to your file every time you'll call .write, until your application will be closed, or until you'll manually close the stream calling .end:

logger.end() // close string

This is a pretty old question, but perhaps this answer can still help someone else.

You can emulate a public constant that is restricted within a class scope by applying the final keyword to a method that returns a pre-defined value, like this:

class Foo {

    // This is a private constant
    final public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

The final keyword on a method prevents an extending class from re-defining the method. You can also place the final keyword in front of the class declaration, in which case the keyword prevents class Inheritance.

To get nearly exactly what Alex was looking for the following code can be used:

final class Constants {

    public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

class Foo {

    static public app()
    {
        return new Constants();
    }
}

The emulated constant value would be accessible like this:

Foo::app()->MYCONSTANT();

With [email protected] :

// declare
@mixin button( $bgcolor:blue ){
    background:$bgcolor;
}

and use without value, button will be blue

//use
.my_button{
    @include button();
}

and with value, button will be red

//use
.my_button{
    @include button( red );
}

works with hexa too

I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.

Here is a very contrived example:

IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));

Here is the extension method:

public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
    return obj == null ? new List<T>() : obj.ToList();
}

In case the given answers still don't help you remove that, try this:

• Manually delete the line in require from composer.json

• Run composer update

Not working for me.

The mode is true, the file perms have been changed, but git says there's no work to do.

git init
git add dir/file
chmod 440 dir/file
git commit -a

The problem seems to be that git recognizes only certain permission changes.

Think about what

if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51))

means. || means "or." The negation of this is (by DeMorgan's Laws):

state == 10 && state == 15 && state == 19...

In other words, the only way that this could be false if if a state equals 10, 15, and 19 (and the rest of the numbers in your or statement) at the same time, which is impossible.

Thus, this statement will always be true. State 15 will never equal state 10, for example, so it's always true that state will either not equal 10 or not equal 15.

Change || to &&.

Also, in most languages, the following:

if (x) {
  return true;
}
else {
  return false;
}

is not necessary. In this case, the method returns true exactly when x is true and false exactly when x is false. You can just do:

return x;

Same thing you'd expect from normal modulo .. e.g. 7 % 4 = 3, 7.3 % 4.0 = 3.3

Beware of floating point accuracy issues.

When you use Fabric for public beta releases (signed with prod config), DON'T USE Google Play App Signing. You will must after build two signed apks!

When you distribute to more play stores (samsung, amazon, xiaomi, ...) you will must again build two signed apks.

So be really carefull with Google Play App Signing.

It's not possible to revert it :/ and Google Play did not after accept apks signed with production key. After enable Google Play App Signing only upload key is accepted...

It really complicate CI distribution...

I think you should be able to use the HTML escape character (&). They can be found at http://www.theukwebdesigncompany.com/articles/entity-escape-characters.php

You can use the dict.fromkeys class method ...

>>> dict.fromkeys(range(5), True)
{0: True, 1: True, 2: True, 3: True, 4: True}

This is the fastest way to create a dictionary where all the keys map to the same value.

But do not use this with mutable objects:

d = dict.fromkeys(range(5), [])
# {0: [], 1: [], 2: [], 3: [], 4: []}
d[1].append(2)
# {0: [2], 1: [2], 2: [2], 3: [2], 4: [2]} !!!

If you don't actually need to initialize all the keys, a defaultdict might be useful as well:

from collections import defaultdict
d = defaultdict(True)

To answer the second part, a dict-comprehension is just what you need:

{k: k for k in range(10)}

You probably shouldn't do this but you could also create a subclass of dict which works somewhat like a defaultdict if you override __missing__:

>>> class KeyDict(dict):
...    def __missing__(self, key):
...       #self[key] = key  # Maybe add this also?
...       return key
... 
>>> d = KeyDict()
>>> d[1]
1
>>> d[2]
2
>>> d[3]
3
>>> print(d)
{}

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

This is the required source code :

public static void openKeypad(final Context context, final View v)

    @Override
    public void run() 
    {
        InputMethodManager inputManager =   (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE); 
        inputManager.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);    
        Log.e("openKeypad", "Inside Handler");
    }
},300);}

You can write your php file to the action attr of form element.
At the php side you can get the form value by $_POST['element_name'].

if a method is not static, that "tells" the compiler that the method requires access to instance-level data in the class, (like a non-static field). This data would not be available unless an instance of the class has been created. So the compiler throws an error if you try to call the method from a static method.. If in fact the method does NOT reference any non-static member of the class, make the method static.

In Resharper, for example, just creating a non-static method that does NOT reference any static member of the class generates a warning message "This method can be made static"

My BASIC interpreter chops beginning and ending quotes with

str->pop_back();
str->erase(str->begin());

Of course, I always expect well-formed BASIC style strings, so I will abort with failed assert if not:

assert(str->front() == '"' && str->back() == '"');

Just my two cents.

There are two operators in Python for the "not equal" condition -

a.) != If values of the two operands are not equal, then the condition becomes true. (a != b) is true.

b.) <> If values of the two operands are not equal, then the condition becomes true. (a <> b) is true. This is similar to the != operator.

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

Eager Loading: Eager Loading helps you to load all your needed entities at once. i.e. related objects (child objects) are loaded automatically with its parent object.

When to use:

1. Use Eager Loading when the relations are not too much. Thus, Eager Loading is a good practice to reduce further queries on the Server.
2. Use Eager Loading when you are sure that you will be using related entities with the main entity everywhere.

Lazy Loading: In case of lazy loading, related objects (child objects) are not loaded automatically with its parent object until they are requested. By default LINQ supports lazy loading.

When to use:

1. Use Lazy Loading when you are using one-to-many collections.
2. Use Lazy Loading when you are sure that you are not using related entities instantly.

NOTE: Entity Framework supports three ways to load related data - eager loading, lazy loading and explicit loading.

You can use .addAll() to add the elements of the second list to the first:

array1.addAll(array2);

Edit: Based on your clarification above ("i want a single String in the new Arraylist which has both name and number."), you would want to loop through the first list and append the item from the second list to it.

Something like this:

int length = array1.size();
if (length != array2.size()) { // Too many names, or too many numbers
    // Fail
}
ArrayList<String> array3 = new ArrayList<String>(length); // Make a new list
for (int i = 0; i < length; i++) { // Loop through every name/phone number combo
    array3.add(array1.get(i) + " " + array2.get(i)); // Concat the two, and add it
}

If you put in:

array1 : ["a", "b", "c"]
array2 : ["1", "2", "3"]

You will get:

array3 : ["a 1", "b 2", "c 3"]

A sha256 is 256 bits long -- as its name indicates.

Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar(64), or even a char(64), as the length is always the same, not varying at all.

And the demo :

$hash = hash('sha256', 'hello, world!');
var_dump($hash);

Will give you :

$ php temp.php
string(64) "68e656b251e67e8358bef8483ab0d51c6619f3e7a1a9f0e75838d41ff368f728"

i.e. a string with 64 characters.

Conditions to create a ACID table in Hive. 1. The table should be stored as ORC file .Only ORC format can support ACID prpoperties for now 2. The table must be bucketed

Properties to set to create ACID table:

set hive.support.concurrency =true;
set hive.enforce.bucketing =true;
set hive.exec.dynamic.partition.mode =nonstrict
set hive.compactor.initiator.on = true;
set hive.compactor.worker.threads= 1;
set hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;

set the property hive.in.test to true in hive.site.xml

After setting all these properties , the table should be created with tblproperty 'transactional' ='true'. The table should be bucketed and saved as orc

CREATE TABLE table_name (col1 int,col2 string, col3 int) CLUSTERED BY col1 INTO 4 
BUCKETS STORED AS orc tblproperties('transactional' ='true');

Now the Hive table can support UPDATE and DELETE queries

Use the sources tab, you can set breakpoints in JavaScript there. In the directory tree underneath it (with the up and down arrow in it), you can select the file you want to debug. You can get out of an error by pressing resume on the right-hand side of the same tab.

With \ you escape special characters

Escapes special characters to literal and literal characters to special.

E.g: /\(s\)/ matches '(s)' while /(\s)/ matches any whitespace and captures the match.

I'm writing an answer only because I do not have enough reputations to comment the accepted answer from apsillers. I agree with his answer, but

If you really want to test if a variable is undeclared, you'll need to catch the ReferenceError ...

is not the only way. One can do just:

this.hasOwnProperty("bar")

to check if there is a variable bar declared in the current context. (I'm not sure, but calling the hasOwnProperty could also be more fast/effective than raising an exception) This works only for the current context (not for the whole current scope).

You should add UIToolbar to top UITextView to make easy rather than using shouldChangeTextIn

In Swift 4

let toolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
        toolbar.barStyle = .default
        toolbar.items = [
            UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil),
            UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(doneAction))
        ]
        textView.inputAccessoryView = toolbar

@objc func doneAction(){
 self.textView.resignFirstResponder()
}

There's no need for all the code mentioned by galambalazs. The cross-browser way to do it in pure JavaScript is simply to test document.readyState:

if (document.readyState === "complete") { init(); }

This is also how jQuery does it.

Depending on where the JavaScript is loaded, this can be done inside an interval:

var readyStateCheckInterval = setInterval(function() {
    if (document.readyState === "complete") {
        clearInterval(readyStateCheckInterval);
        init();
    }
}, 10);

In fact, document.readyState can have three states:

Returns "loading" while the document is loading, "interactive" once it is finished parsing but still loading sub-resources, and "complete" once it has loaded. -- document.readyState at Mozilla Developer Network

So if you only need the DOM to be ready, check for document.readyState === "interactive". If you need the whole page to be ready, including images, check for document.readyState === "complete".

A simple intuitive implementation

public static List<PointF> RemoveDuplicates(List<PointF> listPoints)
{
    List<PointF> result = new List<PointF>();

    for (int i = 0; i < listPoints.Count; i++)
    {
        if (!result.Contains(listPoints[i]))
            result.Add(listPoints[i]);
    }

    return result;
}

Not sure about the exact reproduction steps for the error (HRESULT E_FAIL has been returned from a call to a COM component), but the solution for me was:

1. Close Visual Studio and Repair it through Control Panel.
2. Restart system

After the restart, the error was gone.

UPDATE urls
SET url = REPLACE(url, 'domain1.com/images/', 'domain2.com/otherfolder/')

I have been through a lot of trouble so I came up with my own solution, I created this script, just set the path inside script and db name and run it, it will do the trick

#!/bin/bash

FILES= #absolute or relative path to dump directory
DB=`db` #db name
for file in $FILES
do

    name=$(basename $file)
    collection="${name%.*}"
    echo `mongoimport --db "$DB" --file "$name" --collection "$collection"`

done

If you are using anaconda step 1: where python step 2: open anaconda prompt in administrator mode step 3: cd <python path> step 4: install the package in this location

Google led me to this solution (base64_encode). Hope this helps!

I'm doing the following:

getLocalStorageSizeLimit = function () {

    var maxLength = Math.pow(2,24);
    var preLength = 0;
    var hugeString = "0";
    var testString;
    var keyName = "testingLengthKey";

    //2^24 = 16777216 should be enough to all browsers
    testString = (new Array(Math.pow(2, 24))).join("X");

    while (maxLength !== preLength) {
        try  {

            preLength = testString.length;
            maxLength = Math.ceil(preLength + ((hugeString.length - preLength) / 2));

            testString = hugeString.substr(0, maxLength);
        } catch (e) {
            hugeString = testString;

            maxLength = Math.floor(testString.length - (testString.length - preLength) / 2);
            testString = hugeString.substr(0, maxLength);
        }
    }

    localStorage.removeItem(keyName);

    maxLength = JSON.stringify(this.storageObject).length + maxLength + keyName.length - 2;

    return maxLength;
};

DECLARE @LastChangeDate as date 
SET @LastChangeDate = GETDATE() 

I like a reverse order for loop such as:

int size = list.size();
for (int i = size - 1; i >= 0; i--) {
    if(remove){
        list.remove(i);
    }
}

because it doesn't require learning any new data structures or classes.

Anybody working on legacy software using Visual Studio 6.0 will find that $(Configuration) and $(ProjectDir) macro's are not defined. For post-build/pre-build events, give a relative path starting with the location of your .dsw file(workspace) as the starting point. In relative path dot represents the current directory and .. represents the parent directory. Give a relative path to the file that need to be processed. Example: ( copy /y .\..\..\Debug\mylib.dll .\..\MyProject\Debug\ )

Memcached is multithreaded and fast.

Redis has lots of features and is very fast, but completely limited to one core as it is based on an event loop.

We use both. Memcached is used for caching objects, primarily reducing read load on the databases. Redis is used for things like sorted sets which are handy for rolling up time-series data.

So, It looks something like this:

git rm --cached /config/deploy.rb
echo /config/deploy.rb >> .gitignore

Remove cache for tracked file from git and add that file to .gitignore list

Data can be pulled into an excel from another excel through Workbook method or External reference or through Data Import facility.

If you want to read or even if you want to update another excel workbook, these methods can be used. We may not depend only on VBA for this.

When you add yor map use:

getChildFragmentManager().beginTransaction()
    .replace(R.id.menu_map_container, mapFragment, "f" + shabbatIndex).commit();

instead of .add and instead of getFragmentManager.

Selecting an item in ng-options can be a bit tricky depending on how you set the data source.

After struggling with them for a while I ended up making a sample with most common data sources I use. You can find it here:

http://plnkr.co/edit/fGq2PM?p=preview

Now to make ng-options work, here are some things to consider:

1. Normally you get the options from one source and the selected value from other. For example:
   • states :: data for ng-options
   • user.state :: Option to set as selected
2. Based on 1, the easiest/logical thing to do is to fill the select with one source and then set the selected value trough code. Rarely would it be better to get a mixed dataset.
3. AngularJS allows select controls to hold more than key | label. Many online examples put objects as 'key', and if you need information from the object set it that way, otherwise use the specific property you need as key. (ID, CODE, etc.. As in the plckr sample)

4. The way to set the value of the dropdown/select control depends on #3,

   • If the dropdown key is a single property (like in all examples in the plunkr), you just set it, e.g.: $scope.dropdownmodel = $scope.user.state;

   • If you set the object as key, you need to loop trough the options, even assigning the object will not set the item as selected as they will have different hashkeys, e.g.:

     for (var i = 0, len = $scope.options.length; i < len; i++) {
       if ($scope.options[i].id == savedValue) { // Your own property here:
         console.log('Found target! ');
         $scope.value = $scope.options[i];
         break;
       }
     }
     

You can replace savedValue for the same property in the other object, $scope.myObject.myProperty.

The "this" is already coloured in Javascript.

View->Syntax-> and choose your language to highlight.

Just use:

function getData() {
    $.ajax({
        url : 'example.com',
        type: 'GET',
        success : handleData
    })
}

The success property requires only a reference to a function, and passes the data as parameter to this function.

You can access your handleData function like this because of the way handleData is declared. JavaScript will parse your code for function declarations before running it, so you'll be able to use the function in code that's before the actual declaration. This is known as hoisting.

This doesn't count for functions declared like this, though:

var myfunction = function(){}

Those are only available when the interpreter passed them.

See this question for more information about the 2 ways of declaring functions

This quote is taken from; Version Control with Git

Git runs garbage collection automatically:

• If there are too many loose objects in the repository

• When a push to a remote repository happens

• After some commands that might introduce many loose objects

• When some commands such as git reflog expire explicitly request it

And finally, garbage collection occurs when you explicitly request it using the git gc command. But when should that be? There’s no solid answer to this question, but there is some good advice and best practice.

You should consider running git gc manually in a few situations:

• If you have just completed a git filter-branch . Recall that filter-branch rewrites many commits, introduces new ones, and leaves the old ones on a ref that should be removed when you are satisfied with the results. All those dead objects (that are no longer referenced since you just removed the one ref pointing to them) should be removed via garbage collection.

• After some commands that might introduce many loose objects. This might be a large rebase effort, for example.

And on the flip side, when should you be wary of garbage collection?

• If there are orphaned refs that you might want to recover

• In the context of git rerere and you do not need to save the resolutions forever

• In the context of only tags and branches being sufficient to cause Git to retain a commit permanently

• In the context of FETCH_HEAD retrievals (URL-direct retrievals via git fetch ) because they are immediately subject to garbage collection

I simplification for Science_Fiction's answer I think is to use the exclusive or function so you can just have:

if(checkbox1.checked ^ checkbox2.checked)
{
//do stuff
}

That is assuming you want to do the same thing for both situations.

Try this:

$(document).ready(function(event) {
    $('#countrylist').change(function(e){
         // put code here
     }).change();
});

Define the change event, and trigger it immediately. This ensures the event handler is defined before calling it.

Might be late to answer the original poster, but someone else might benefit from the shorthand notation, and this follows jQuery's chaining, etc

-(void)saveToUserDefaults:(NSString*)string_to_store keys:(NSString *)key_for_the_String

    if (standardUserDefaults) {
        [standardUserDefaults setObject:string_to_store forKey:key_for_the_String];
        [standardUserDefaults synchronize];
    }
}

And call it by:

[self saveToUserDefaults:@"string_to_store" : @"key_for_the_string"];

Retrieve the string by using:

NSString * stored_string = [[NSUserDefaults standardUserDefaults] stringforkey:key_for_the_String]

A trick I learned from this PR if you don't want to define it as a static final variable but want to save a bit of overhead and guarantee thread safe.

private static final ThreadLocal<ObjectMapper> om = new ThreadLocal<ObjectMapper>() {
    @Override
    protected ObjectMapper initialValue() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        return objectMapper;
    }
};

public static ObjectMapper getObjectMapper() {
    return om.get();

According to your updated problem

<div class="home">
  <span>blah</span>
  <p class="red">first</p>
  <p class="red">second</p>
  <p class="red">third</p>
  <p class="red">fourth</p>
</div>

how about

.home span + .red{
      border:1px solid red;
    }

This will select class home, then the element span and finally all .red elements that are placed immediately after span elements.

Solution with 1 div and NO transparent image:

You can use the multibackground CSS3 feature and put two backgrounds: one with the image, another with a transparent panel over it (cause I think there's no way to set directly the opacity of the background image):

background: -moz-linear-gradient(top, rgba(0, 0, 0, 0.7) 0%, rgba(0, 0, 0, 0.7) 100%), url(bg.png) repeat 0 0, url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: -moz-linear-gradient(top, rgba(255,255,255,0.7) 0%, rgba(255,255,255,0.7) 100%), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0.7)), color-stop(100%,rgba(255,255,255,0.7))), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: -webkit-linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,0.7) 100%), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: -o-linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,0.7) 100%), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: -ms-linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,0.7) 100%), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

background: linear-gradient(to bottom, rgba(255,255,255,0.7) 0%,rgba(255,255,255,0.7) 100%), url(https://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png) repeat 0 0;

You can't use rgba(255,255,255,0.5) because alone it is only accepted on the back, so you I've used generated gradients for each browser for this example (that's why it is so long). But the concept is the following:

background: tranparentColor, url("myImage");

I was getting the same error when i switched to STS version 3.8.3 And imported my entire workspace to the new STS.

Apparently the "Boot Spring App" instance was defective. (i run from STS)

If this is your problem, Simply create the Boot run configuration again.

For those having optional props that need default values. Credit here :)

interface Props {
  firstName: string;
  lastName?: string;
}

interface DefaultProps {
  lastName: string;
}

type PropsWithDefaults = Props & DefaultProps;

export class User extends React.Component<Props> {
  public static defaultProps: DefaultProps = {
    lastName: 'None',
  }

  public render () {
    const { firstName, lastName } = this.props as PropsWithDefaults;

    return (
      <div>{firstName} {lastName}</div>
    )
  }
}

function getTrimmedUrl($link)
{
    $str = str_replace(["www.","https://","http://"],[''],$link);
    $link = explode("/",$str);
    return strtolower($link[0]);                
}

You can use the JSON.parse() for that.

See docs at MDN

Example:

var myObj = JSON.parse('{"p": 5}');
console.log(myObj);

Here's an alternate

req.hostname

Read about it in the Express Docs.

For some reason, I get that error unless I add the "bash" clarifier. Even adding "#!/bin/bash" to the top of my entrypoint file didn't help.

ENTRYPOINT [ "bash", "entrypoint.sh" ]

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

another solution is to a create a custom view that extend TextView as shown below

public class UnderLineTextView extends TextView {

    public UnderLineTextView(Context context) {
        super(context);
        this.setPaintFlags(Paint.UNDERLINE_TEXT_FLAG);
    }

    public UnderLineTextView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        this.setPaintFlags(Paint.UNDERLINE_TEXT_FLAG);
    }

}

and just add to xml as shown below

<yourpackage.UnderLineTextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="underline text"
 />

On git for Windows you can also reinstall and select the Windows native certificate validation method (OpenSSL is default). This will skip the OpenSSL verification and instead use the Windows native one, which doesn't require maintaining a separate tool (OpenSSL) and certificates.

Worked perfectly for me :)

The general solution could be a caching iterator. A properly implemented caching iterator works with any Iterator, and saves memory. PHP SPL has a CachingIterator, but it is very odd, and has very limited functionality. However, you can write your own lookahead iterator like this:

<?php

class NeighborIterator implements Iterator
{

    protected $oInnerIterator;

    protected $hasPrevious = false;
    protected $previous = null;
    protected $previousKey = null;

    protected $hasCurrent = false;
    protected $current = null;
    protected $currentKey = null;

    protected $hasNext = false;
    protected $next = null;
    protected $nextKey = null;

    public function __construct(Iterator $oInnerIterator)
    {
        $this->oInnerIterator = $oInnerIterator;
    }

This has worked for me in the past and it will even expand environment variables in the file if it can.

for /F "delims=" %%a in (LogName.txt) do (
     echo %%a>>MyDestination.txt
)

Change it to this:

switch (enumExample) {
    case VALUE_A: {
        //..
        break;
    }
}

The clue is in the error. You don't need to qualify case labels with the enum type, just its value.

I needed either: both -alpha background and -flatten, or -fill.

I made a new PNG with a transparent background and a red dot in the middle.

convert image.png -background green -alpha off green.png failed: it produced an image with black background

convert image.png -background green -alpha background -flatten green.png produced an image with the correct green background.

Of course, with another file that I renamed image.png, it failed to do anything. For that file, I found that the color of the transparent pixels was "#d5d5d5" so I filled that color with green:

convert image.png -fill green -opaque "#d5d5d5" green.png replaced the transparent pixels with the correct green.

The first set of errors, for the missing vtable, are caused because you do not implement takeaway::textualGame(); instead you implement a non-member function, textualGame(). I think that adding the missing takeaway:: will fix that.

The cause of the last error is that you're calling a virtual function, initialData(), from the constructor of gameCore. At this stage, virtual functions are dispatched according to the type currently being constructed (gameCore), not the most derived class (takeaway). This particular function is pure virtual, and so calling it here gives undefined behaviour.

Two possible solutions:

• Move the initialisation code for gameCore out of the constructor and into a separate initialisation function, which must be called after the object is fully constructed; or
• Separate gameCore into two classes: an abstract interface to be implemented by takeaway, and a concrete class containing the state. Construct takeaway first, and then pass it (via a reference to the interface class) to the constructor of the concrete class.

I would recommend the second, as it is a move towards smaller classes and looser coupling, and it will be harder to use the classes incorrectly. The first is more error-prone, as there is no way be sure that the initialisation function is called correctly.

One final point: the destructor of a base class should usually either be virtual (to allow polymorphic deletion) or protected (to prevent invalid polymorphic deletion).

Using this,

        String s = "03/24/2013 21:54";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
        try
        {
            Date date = simpleDateFormat.parse(s);

            System.out.println("date : "+simpleDateFormat.format(date));
        }
        catch (ParseException ex)
        {
            System.out.println("Exception "+ex);
        }

This is actually possible to do with Object.create. It will not work for "non defined" properties. But for the ones that has been given a default value.

var defaults = {
    a: 'test1',
    b: 'test2'
};

Then when you create your properties object you do it with Object.create

properties = Object.create(defaults);

Now you will have two object where the first object is empty, but the prototype points to the defaults object. To test:

console.log('Unchanged', properties);
properties.a = 'updated';
console.log('Updated', properties);
console.log('Defaults', Object.getPrototypeOf(properties));

You can try using the ReadDir function in the io/ioutil package. Per the docs:

ReadDir reads the directory named by dirname and returns a list of sorted directory entries.

The resulting slice contains os.FileInfo types, which provide the methods listed here. Here is a basic example that lists the name of everything in the current directory (folders are included but not specially marked - you can check if an item is a folder by using the IsDir() method):

package main

import (
    "fmt"
    "io/ioutil"
     "log"
)

func main() {
    files, err := ioutil.ReadDir("./")
    if err != nil {
        log.Fatal(err)
    }
 
    for _, f := range files {
            fmt.Println(f.Name())
    }
}

inline

import functools

#: not key(c) in d
d = {"a": "avalue", "b": "bvalue", "d": "dvalue"}

entitiesToREmove = ('a', 'b', 'c')

#: python2
map(lambda x: functools.partial(d.pop, x, None)(), entitiesToREmove)

#: python3

list(map(lambda x: functools.partial(d.pop, x, None)(), entitiesToREmove))

print(d)
# output: {'d': 'dvalue'}

Yet another option is binascii.hexlify:

a = [0,1,2,3,127,200,255]
print binascii.hexlify(bytes(bytearray(a)))

prints

000102037fc8ff

This is also the fastest version for large strings on my machine.

In Python 2.7 or above, you could improve this even more by using

binascii.hexlify(memoryview(bytearray(a)))

saving the copy created by the bytes call.

In java script calculate width using following code

var scrollX = $(window).width()*58/100;
var oTable = $('#reqAllRequestsTable').dataTable({
    "sScrollX": scrollX
    } );

Actually, a Swing component does have multiple dimensions, as:

• current size - setSize() and setBounds() sets this
• minimum size - setMinimumSize() sets this
• preferred size - setPerferredSize() sets this
• maximum size - setMaximumSize() sets this.

SetBounds is a shortcut for setting current size plus location of the widget if you don't use any layout manager.

If you use a layout manager, it is the responsibility of the layout manager to lay out your components, taking into account the preferred size you set, and ensuring that the comonent never gets smaller than its minimumSize or bigger than its maximumSize.

In this case, the layoutManager will call setSize (or setBounds), and you can not really control the position or dimension of the component.

The whole point of using a layout manager is to have a platform and window-size independent way of laying out your components automatically, therefore you don't expect to call setSize from your code.

(Personal comment: There are buggy layout managers, I personally hate all of them and rolled my own, which offers the flexibility of MigLayout without the learning curve.)

I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)

It supports:

• Comma Formatting E.g. 1234567 becomes 1,234,567.
• Prefixing with "Thousand(K),Million(M),Billion(B),Trillion(T)".
• Precision of 0 through 15.
• Precision re-sizing (Means if you want 6 digit precision, but only have 3 available digits it forces it to 3).
• Prefix lowering (Means if the prefix you choose is too large it lowers it to a more suitable prefix).

The code can be found here. You call it like this:

public static void main(String[])
{
   int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
   String formatted = ValueFormat.format(1234567, settings);
}

I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.

Although this thread is 3 years old, here is my solution:

$(function ()
{
    keep_fields_uptodate();
});

function keep_fields_uptodate()
{
    // Keep all fields up to date!
    var $inputDate = $("input[type='date']");
    $inputDate.blur(function(event)
    {
        $("input").trigger("change");
    });
}

Use Arrays.asList:

if( Arrays.asList("a","b","c").contains("a") )

I ended up finding git attributes. Trying it. Working so far. Did not check all scenarios yet. But it should be the solution.

Merge Strategies - Git attributes

There are a lot of great answers here, but I want to come with my 50 cents.

What all of these answers are missing is a simple analogy which would work for a person who just starts his journey in the programming languages.

Hopefully, I will fill this gap with this analogy:

Object Literal Creation vs Constructor-based Syntax

Feel the difference with a sentence creation.

If I have a sentence "I like cheese", I can tell you clearly and loudly (literally, or verbatim): I like cheese.

This is my literal (word by word) creation of the sentence.

All other ways are some tricky ways of making you to understand of what sentence I created exactly. For example, I tell you:

1. In my sentence, the subject is "I", the object is "cheese", and the predicate is "to like". This is another way of YOU to learn without any ambiguities the very same sentence: "I like cheese".

Or,

2. My sentence has 3 words: the first one is the n-th word in the English dictionary, the the second one is the m-th word in the English dictionary and the last one is the l-th word in the English dictionary.

In this case, you also come to the same result: you know exactly what the sentence is.

You can devise any other methods which would differ from "word-by-word" sentence creation (LITERAL), and which would be INDIRECT (non literal, non verbatim) method of sentence creation.

I think this is the core concept which lays here.

A late post, but for those who searched this post.

Imagine this:

    [Authorize(Roles = "Administrator")]
    [Authorize(Roles = "Director")]
    [Authorize(Roles = "Human Resources")]
    [HttpGet]
    public ActionResult GetUserData(string UserIdGuidKey)
    {
        if (UserIdGuidKey!= null)
        {
            var guidUserId = new Guid(UserIdGuidKey);
            var memuser = Membership.GetUser(guidUserId);
            var profileuser = Profile.GetUserProfile(memuser.UserName);
            var list = new {
                              UserName = memuser.UserName,
                              Email = memuser.Email ,
                              IsApproved = memuser.IsApproved.ToString() ,
                              IsLockedOut = memuser.IsLockedOut.ToString() ,
                              LastLockoutDate = memuser.LastLockoutDate.ToString() ,
                              CreationDate = memuser.CreationDate.ToString() ,
                              LastLoginDate = memuser.LastLoginDate.ToString() ,
                              LastActivityDate = memuser.LastActivityDate.ToString() ,
                              LastPasswordChangedDate = memuser.LastPasswordChangedDate.ToString() ,
                              IsOnline = memuser.IsOnline.ToString() ,
                              FirstName = profileuser.FirstName ,
                              LastName = profileuser.LastName ,
                              NickName = profileuser.NickName ,
                              BirthDate = profileuser.BirthDate.ToString() ,
            };
            return Json(list, JsonRequestBehavior.AllowGet);
        }
        return Redirect("Index");
    }

As you can see, I'm utilizing C# 3.0's feature for creating the "Auto" Generics. It's a bit lazy, but I like it and it works. Just a note: Profile is a custom class I've created for my web application project.

It is what it says, you just cannot instantiate an abstract class. You need to implement it first, then instantiate that class.

IUser user = new User();

$(<img />).attr('src','http://somedomain.com/image.jpg');

Should be better than ajax because if its a gallery and you are looping through a list of pics, if the image is already in cache, it wont send another request to server. It will request in the case of jQuery/ajax and return a HTTP 304 (Not modified) and then use original image from cache if its already there. The above method reduces an empty request to server after the first loop of images in the gallery.

Though I tend to agree with @AlekDavis' comment, there are nonetheless several ways to do this in the NT shell.

The approach I would take advantage of the SHIFT command and IF conditional branching, something like this...

@ECHO OFF

SET man1=%1
SET man2=%2
SHIFT & SHIFT

:loop
IF NOT "%1"=="" (
    IF "%1"=="-username" (
        SET user=%2
        SHIFT
    )
    IF "%1"=="-otheroption" (
        SET other=%2
        SHIFT
    )
    SHIFT
    GOTO :loop
)

ECHO Man1 = %man1%
ECHO Man2 = %man2%
ECHO Username = %user%
ECHO Other option = %other%

REM ...do stuff here...

:theend

You can use slice with no arguments to copy an array:

var foo,
    bar;
foo = [3,1,2];
bar = foo.slice().sort();

That's not JSON at all, it's just Javascript objects. JSON is a text representation of data, that uses a subset of the Javascript syntax.

The reason that you can't find any information about manipulating JSON using jQuery is because jQuery has nothing that can do that, and it's generally not done at all. You manipulate the data in the form of Javascript objects, and then turn it into a JSON string if that is what you need. (jQuery does have methods for the conversion, though.)

What you have is simply an object that contains an array, so you can use all the knowledge that you already have. Just use data.items to access the array.

For example, to add another item to the array using dynamic values:

// The values to put in the item
var id = 7;
var name = "The usual suspects";
var type = "crime";
// Create the item using the values
var item = { id: id, name: name, type: type };
// Add the item to the array
data.items.push(item);

The ps solution was nearly what I needed and with some bash thrown in does exactly what the original question asked for: to see per-core usage of specific processes

This shows per-core usage of multi-threaded processes too.

Use like: cpustat `pgrep processname` `pgrep otherprocessname` ...

#!/bin/bash

pids=()
while [ $# != 0 ]; do
        pids=("${pids[@]}" "$1")
        shift
done

if [ -z "${pids[0]}" ]; then
        echo "Usage: $0 <pid1> [pid2] ..."
        exit 1
fi

for pid in "${pids[@]}"; do
        if [ ! -e /proc/$pid ]; then
                echo "Error: pid $pid doesn't exist"
                exit 1
        fi
done

while [ true ]; do
        echo -e "\033[H\033[J"
        for pid in "${pids[@]}"; do
                ps -p $pid -L -o pid,tid,psr,pcpu,comm=
        done
        sleep 1
done

Note: These stats are based on process lifetime, not the last X seconds, so you'll need to restart your process to reset the counter.

You can use numpy.count_nonzero, converting the whole into a one-liner:

za = numpy.count_nonzero(numpy.asarray(o31)<200)  #as written in the code

See mozilla.org's write-up on how CORS works.

You'll need your server to send back the proper response headers, something like:

Access-Control-Allow-Origin: http://foo.example
Access-Control-Allow-Methods: POST, PUT, GET, OPTIONS
Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization

Bear in mind you can use "*" for Access-Control-Allow-Origin that will only work if you're trying to pass Authentication data. In that case, you need to explicitly list the origin domains you want to allow. To allow multiple domains, see this post

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

Thanks to this link: Less Aggressive Compilation with CSS3 calc

In this version, month, day, and year determines which days to block on the calendar.

$(document).ready(function (){
  var d         = new Date();
  var natDays   = [[1,1,2009],[1,1,2010],[12,31,2010],[1,19,2009]];

  function nationalDays(date) {
    var m = date.getMonth();
    var d = date.getDate();
    var y = date.getFullYear();

    for (i = 0; i < natDays.length; i++) {
      if ((m == natDays[i][0] - 1) && (d == natDays[i][1]) && (y == natDays[i][2]))
      {
        return [false];
      }
    }
    return [true];
  }
  function noWeekendsOrHolidays(date) {
    var noWeekend = $.datepicker.noWeekends(date);
      if (noWeekend[0]) {
        return nationalDays(date);
      } else {
        return noWeekend;
    }
  }
  $(function() { 
    $(".datepicker").datepicker({

      minDate: new Date(d.getFullYear(), 1 - 1, 1),
      maxDate: new Date(d.getFullYear()+1, 11, 31),

      hideIfNoPrevNext: true,
      beforeShowDay: noWeekendsOrHolidays,
     });

I had this exact same problem. I fixed it by adding the following line to my FindOpenCV.cmake file. Put it anywhere at the top before the rest of the code.

set (OpenCV_DIR /home/cmake/opencv/compiled) #change the path to match your complied directory of opencv

Basically you are telling FindOpenCV.cmake where to find opencv files assuming the other compilation can find the FindOpenCV.cmake

Use MomentJS.

function getXDaysBeforeDate(referenceDate, x) {_x000D_
  return moment(referenceDate).subtract(x , 'day').format('MMMM Do YYYY, h:mm:ss a');_x000D_
}_x000D_
_x000D_
var yourDate = new Date(); // let's say today_x000D_
var valueOfX = 7; // let's say 7 days before_x000D_
_x000D_
console.log(getXDaysBeforeDate(yourDate, valueOfX));

The below should work for you assuming Strings is the array that you are searching within:

Arrays.binarySearch(Strings,"mykeytosearch",mysearchComparator);

where mykeytosearch is the string that you want to test for existence within the array. mysearchComparator - is a comparator that would be used to compare strings.

Refer to Arrays.binarySearch for more information.

DECLARE @CMonth int=null
DECLARE @lCYear int=null

SET @lCYear=(SELECT  DATEPART(YEAR,GETDATE()))
SET @CMonth=(SELECT  DATEPART(MONTH,GETDATE()))

I've been fighting with this for quite a while. Since this is the first hit on Google when I searched for the solution, let me post where I've gotten so far.

SET @d := '2011-09-01';
SELECT @d AS d, cast( @d := DATE_ADD( @d , INTERVAL 1 DAY ) AS DATE ) AS new_d
  FROM [yourTable]
  WHERE @d <= '2012-05-01';

Replace [yourTable] with a table from your database. The trick is that the number of rows in the table you select must be >= the number of dates you want to be returned. I tried using the table placeholder DUAL, but it would only return one single row.

An other solution is to use the response.status function. This will give you the http status wich is returned by the ajax call.

function checkHttpStatus(url) {     
    $.ajax({
        type: "GET",
        data: {},
        url: url,
        error: function(response) {
            alert(url + " returns a " + response.status);
        }, success() {
            alert(url + " Good link");
        }
    });
}

You can do the following:

=Datevalue(text)+timevalue(text) .

Go into different types of date formats and choose:

dd-mm-yyyy mm:ss am/pm .

Precision, Scale, and Length in the SQL Server 2000 documentation reads:

Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2.

For rails 2.3.2 you can start server by:

ruby script/server

------------------------------------------

Use Navigator:-

The navigator is an object that contains all information about the client machine's browser.

navigator.appName returns the name of the client machine's browser.

navigator.appName === 'Microsoft Internet Explorer' ||  !!(navigator.userAgent.match(/Trident/) || navigator.userAgent.match(/rv:11/)) || (typeof $.browser !== "undefined" && $.browser.msie === 1) ? alert("Please dont use IE.") : alert("This is not IE")

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

string.join the list values separated by commas, and use the format operator to form a query string.

myquery = "select name from studens where id in (%s)" % ",".join(map(str,mylist))

Though this question has an answer, I resolved it differently when I had the same issue. I had this issue when I copied folders with the option Create Folder references; then the above solution of adding the folder to the build_path worked. But when the folder was added using the Create groups for any added folder option, the headers were picked up automatically.

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

In theory like so:

# BOLD
$ echo -e "\033[1mThis is a BOLD line\033[0m"
This is a BOLD line

# Using tput
tput bold 
echo "This" #BOLD
tput sgr0 #Reset text attributes to normal without clear.
echo "This" #NORMAL

# UNDERLINE
$ echo -e "\033[4mThis is a underlined line.\033[0m"
This is a underlined line. 

But in practice it may be interpreted as "high intensity" color instead.

Goto Current Project

RightClick->Properties->Java Build Path->Add Jar Files into Libraries -> Click OK

Then it is added into the Referenced Libraries File in your Current Project .

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

According to Wikipedia:

[...] A traditional pipe is "unnamed" because it exists anonymously and persists only for as long as the process is running. A named pipe is system-persistent and exists beyond the life of the process and must be "unlinked" or deleted once it is no longer being used. Processes generally attach to the named pipe (usually appearing as a file) to perform IPC (inter-process communication).

Easy to explain:

Lets assume the following

URI is your Name

URL is your address with your name in-order to communicate with you.

• my name is Loyola

  Loyola is URI

• my address is TN, Chennai 600001.

TN, Chennai 600 001, Loyola is URL

Hope you understand,

Now lets see a precise example

http://www.google.com/fistpage.html

in the above you can communicate with a page called firstpage.html (URI) using following http://www.google.com/fistpage.html(URL).

Hence URI is subset of URL but not vice-versa.

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

sys.path returns the list of paths

ref

sys.path

A list of strings that specifies the search path for modules. Initialized from the environment variable PYTHONPATH, plus an installation-dependent default.

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

import sys
dirs=sys.path
for path in dirs:
   print(path)

or you can print only first path by

print(dir[0])

try this

the solution is, work with callbacks like this

$(function() {

    var jForm = $('form[name=form]');
    var jPWField = $('#employee_password');

    function getCheckedState() {
        return jForm.data('checked_state');
    };

    function setChecked(s) {
        jForm.data('checked_state', s);
    };


    jPWField.change(function() {
        //reset checked thing
        setChecked(null);
    }).trigger('change');

    jForm.submit(function(){
        switch(getCheckedState()) {
            case 'valid':
                return true;
            case 'invalid':
                //invalid, don submit
                return false;
            default:
                //make your check
                var password = $.trim(jPWField.val());

                $.ajax({
                    type: "POST",
                    async: "false",
                    url: "checkpass.php",
                    data: {
                        "password": $.trim(jPWField.val);
                    }
                    success: function(html) {
                        var arr=$.parseJSON(html);
                        setChecked(arr == "Successful" ? 'valid': 'invalid');
                        //submit again
                        jForm.submit();
                    }
                    });
                return false;
        }

    });
 });

It's safer to add the underscore or $ to the term you're searching for so it's less likely to match other elements which end in the same ID:

$("element[id$=_txtTitle]")

(where element is the type of element you're trying to find - eg div, input etc.

(Note, you're suggesting your IDs tend to have $ signs in them, but I think .NET 2 now tends to use underscores in the ID instead, so my example uses an underscore).

Addressing the first question, if you need to take several rows grouped by certain criteria with the other column with max value you can do something like this:

var query =
    from u1 in table
    join u2 in (
        from u in table
        group u by u.GroupId into g
        select new { GroupId = g.Key, MaxStatus = g.Max(x => x.Status) }
    ) on new { u1.GroupId, u1.Status } equals new { u2.GroupId, Status = u2.MaxStatus}
    select u1;

Try forfiles:

forfiles /p C:\Temp /m file1.txt /c "cmd /c echo @fsize"

The forfiles command runs command c for each file m in directory p.

The variable @fsize is replaced with the size of each file.

If the file C:\Temp\file1.txt is 27 bytes, forfiles runs this command:

cmd /c echo 27

Which prints 27 to the screen.

As a side-effect, it clears your screen as if you had run the cls command.

I created a little javascript tool to style elements on screen size without using media queries or recompiling bootstrap css:

https://github.com/Heras/Responsive-Breakpoints

Just add class responsive-breakpoints to any element, and it will automagically add xs sm md lg xl classes to those elements.

As mentioned in previous posts already, OPTIONS requests are there for a reason. If you have an issue with large response times from your server (e.g. overseas connection) you can also have your browser cache the preflight requests.

Have your server reply with the Access-Control-Max-Age header and for requests that go to the same endpoint the preflight request will have been cached and not occur anymore.

I think you could do something like this

    authorsList = (from a in authorsList
                  where !authors.Contains(a)
                  select a).ToList();

Although I think the solutions already given solve the problem in a more readable way.

EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245

To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:

nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000

You can do multiple tests with:

while true; do printf '' | nc -l localhost 8000; done

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

Most of the time these settings are also defined in a jndi.properties file. Do you have that one lying around somewhere?

you could use exists with a filter:

Content.objects.filter(name="baby").exists()
#returns False or True depending on if there is anything in the QS

just an alternative for if you only want to know if it exists

That InvocationTargetException is probably wrapping up your ArrayIndexOutOfBoundsException. There is no telling upfront when using reflection what that method can throw -- so rather than using a throws Exception approach, all the exceptions are being caught and wrapped up in InvocationTargetException.

Add offset8 to your class, for example:

<div class="offset8">aligns to the right</div>

You can set it as a no title bar theme in the activity's xml in the AndroidManifest

    <activity 
        android:name=".AnActivity"
        android:label="@string/a_string"
        android:theme="@android:style/Theme.NoTitleBar">
    </activity>

require 'net/http'
result = Net::HTTP.get(URI.parse('http://www.example.com/about.html'))
# or
result = Net::HTTP.get(URI.parse('http://www.example.com'), '/about.html')
