You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.

According to the page:

This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.

Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.

Just use the following for a "minimal" C# installation:

vs_Community.exe --layout f:\vs2017c --lang en-US --add Microsoft.VisualStudio.Workload.ManagedDesktop

This works for sure. The error in your first commandline was the trailing backslash. Without it it works. You don't have to download all..

You can add for example the following workloads (or a subset) to the commandline:

Microsoft.VisualStudio.Workload.Data Microsoft.VisualStudio.Workload.NetWeb Microsoft.VisualStudio.Workload.Universal Microsoft.VisualStudio.Workload.NetCoreTools

Sometimes the downloader seems to not like too much packages. But you can download the packages (add the other workloads) step-by-step, this works. Like you want.

The interesting thing. The installer afterwards will download (only) the packages you selected which you have NOT downloaded before, so it is quite smart (in this point).

(Of course there are more packages available).

I have created step by step instructions on how to do this as I also was very confused about how to get this working.

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

I had the same issue when trying to use php composer install in a local directory on my Apache server for a laravel project I cloned from Github. My problem was I had already setup composer globally on my Ubuntu 18 machine.
Adding sudo instead of php started the install of a whole slew of packages listed in the json.lock file i.e. sudo composer install.

Assuming you're dealing with Windows 7 x64 and something that was previously installed with some sort of an installer, you can open regedit and search the keys under

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

(which references 32-bit programs) for part of the name of the program, or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

(if it actually was a 64-bit program).

If you find something that matches your program in one of those, the contents of UninstallString in that key usually give you the exact command you are looking for (that you can run in a script).

If you don't find anything relevant in those registry locations, then it may have been "installed" by unzipping a file. Because you mentioned removing it by the Control Panel, I gather this likely isn't then case; if it's in the list of programs there, it should be in one of the registry keys I mentioned.

Then in a .bat script you can do

if exist "c:\program files\whatever\program.exe" (place UninstallString contents here)
if exist "c:\program files (x86)\whatever\program.exe" (place UninstallString contents here)

you need to edit the "c:\Program Files\wamp\bin\php\php5.3.13\php.ini" file search for: ;extension=php_openssl.dll

remove the semicolon at the beginning

note: if saving the file doesn't work then you need to edit it as administrator. (on win7) go to start menu, search for notepad, right-click on notepad, click "Run As Administrator"

in the composer installation windows just click back then next (or close it and start again) and it should work

May be I am really late for reply, Seriously guys this error resolution took hours of time, i tried every possible solution.

1. installing IIS
2. changing Power Shell from environment variable.
3. Deleting the local group

While, the solution is really really simple. If you look closely in environment variable PSModulePath there will be commas at end of the value simply remove those and enjoy

$ErrorActionPreference = "Stop" will get you part of the way there (i.e. this works great for cmdlets).

However for EXEs you're going to need to check $LastExitCode yourself after every exe invocation and determine whether that failed or not. Unfortunately I don't think PowerShell can help here because on Windows, EXEs aren't terribly consistent on what constitutes a "success" or "failure" exit code. Most follow the UNIX standard of 0 indicating success but not all do. Check out the CheckLastExitCode function in this blog post. You might find it useful.

PUSHD and POPD should help in your case.

@echo off
:: Create a temporary drive letter mapped to your UNC root location
:: and effectively CD to that location
pushd \\server\soft

:: Do your work
WP15\setup.exe
robocopy.exe "WP15\Custom" /copyall "C:\Program Files (x86)\WP\Custom Templates"
Regedit.exe /s WPX5\Custom\Migrate.reg

:: Remove the temporary drive letter and return to your original location
popd

Type PUSHD /? from the command line for more information.

There's no supported way to do this, but won't you have to examine the files related to each installer to figure out how to actually install them after extracting them? Assuming you can spend the time to figure out which command-line applies, here are some candidate parameters that normally allow you to extract an installation.

MSI Based (may not result in a usable image for an InstallScript MSI installation):

• setup.exe /a /s /v"/qn TARGETDIR=\"choose-a-location\""

  or, to also extract prerequisites (for versions where it works),

• setup.exe /a"choose-another-location" /s /v"/qn TARGETDIR=\"choose-a-location\""

InstallScript based:

• setup.exe /s /extract_all

Suite based (may not be obvious how to install the resulting files):

• setup.exe /silent /stage_only ISRootStagePath="choose-a-location"

As paxdiablo said make -f pax.mk would execute the pax.mk makefile, if you directly execute it by typing ./pax.mk, then you would get syntax error.

Also you can just type make if your file name is makefile/Makefile.

Suppose you have two files named makefile and Makefile in the same directory then makefile is executed if make alone is given. You can even pass arguments to makefile.

Check out more about makefile at this Tutorial : Basic understanding of Makefile

As in the answer of Escobar Ceaser, I suggest to use quotes arround the whole path. It's the common way to wrap the whole path in "", not only separate directory names within the path.

I had a similar issue that it didn't work for me. But it was no option to use "" within the path for separate directory names because the path contained environment variables, which theirself cover more than one directory hierarchies. The conclusion was that I missed the space between the closing " and the (

The correct version, with the space before the bracket, would be

If NOT exist "C:\Documents and Settings\John\Start Menu\Programs\Software Folder" (
 start "\\filer\repo\lab\software\myapp\setup.exe"
 pause
) 

.msi files are windows installer files without the windows installer runtime, setup.exe can be any executable programm (probably one that installs stuff on your computer)

You can put this in your .h file for your class and define it as property, in XCode 7:

@property int  (*stuffILike) [10];

In order to have a popop with Chrome 14+, you need to do the following :

jQuery(window).bind('beforeunload', function(){
    return 'my text';
});

The user will be asked if he want to stay or leave.

This should fix your problem: android:layout_weight="1".

This excellent answer to a similar question (that I could not find before, unfortunately) helped me solve the problem.

Copying Content from referenced answer :

SQL Developer will look in the following location in this order for a tnsnames.ora file

$HOME/.tnsnames.ora
$TNS_ADMIN/tnsnames.ora
TNS_ADMIN lookup key in the registry
/etc/tnsnames.ora ( non-windows )
$ORACLE_HOME/network/admin/tnsnames.ora
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

If your tnsnames.ora file is not getting recognized, use the following procedure:

Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...
In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

Confirm the os is recognizing this environmental variable

From the Windows command line: echo %TNS_ADMIN%

From linux: echo $TNS_ADMIN

Restart SQL Developer Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

A very simple method for single-line files, requiring GNU echo from coreutils:

/bin/echo -n $(cat $file)

This script helps you to switch over from a Parent window to a Child window and back cntrl to Parent window

String parentWindow = driver.getWindowHandle();
Set<String> handles =  driver.getWindowHandles();
   for(String windowHandle  : handles)
       {
       if(!windowHandle.equals(parentWindow))
          {
          driver.switchTo().window(windowHandle);
         <!--Perform your operation here for new window-->
         driver.close(); //closing child window
         driver.switchTo().window(parentWindow); //cntrl to parent window
          }
       }

I used jQuery .scroll() function to track the event of the toolbar scroll value using scrollTop. I then used a conditional to determine if it was greater than the value on what I wanted to replace. In the below example it was "Results". If the value was true then the results-label added a class 'fixedSimilarLabel' and the new styles were then taken into account.

    $('.toolbar').scroll(function (e) {
//console.info(e.currentTarget.scrollTop);
    if (e.currentTarget.scrollTop >= 130) {
        $('.results-label').addClass('fixedSimilarLabel');
    }
    else {      
        $('.results-label').removeClass('fixedSimilarLabel');
    }
});

It looks like that's an "unhandled exception", meaning the cmdlet itself hasn't been coded to recognize and handle that exception. It blew up without ever getting to run it's internal error handling, so the -ErrorAction setting on the cmdlet never came into play.

Update 2015-06

Based on antoinepairet's comment/example:

Using uib-collapse attribute provides animations: http://plnkr.co/edit/omyoOxYnCdWJP8ANmTc6?p=preview

<nav class="navbar navbar-default" role="navigation">
    <div class="navbar-header">

        <!-- note the ng-init and ng-click here: -->
        <button type="button" class="navbar-toggle" ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="#">Brand</a>
    </div>

    <div class="collapse navbar-collapse" uib-collapse="navCollapsed">
        <ul class="nav navbar-nav">
        ...
        </ul>
    </div>
</nav>

Ancient..

I see that the question is framed around BS2, but I thought I'd pitch in with a solution for Bootstrap 3 using ng-class solution based on suggestions in ui.bootstrap issue 394:

The only variation from the official bootstrap example is the addition of ng- attributes noted by comments, below:

<nav class="navbar navbar-default" role="navigation">
  <div class="navbar-header">

    <!-- note the ng-init and ng-click here: -->
    <button type="button" class="navbar-toggle" ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
  </div>

  <!-- note the ng-class here -->
  <div class="collapse navbar-collapse" ng-class="{'in':!navCollapsed}">

    <ul class="nav navbar-nav">
    ...

Here is an updated working example: http://plnkr.co/edit/OlCCnbGlYWeO7Nxwfj5G?p=preview (hat tip Lars)

This seems to works for me in simple use cases, but you'll note in the example that the second dropdown is cut off… good luck!

Stack Overflow has solved a similar problem with long lines of code by using a DIV and having overflow-x:auto. CSS can't break up words for you.

select * from tempdb.sys.columns where object_id =
object_id('tempdb..#mytemptable');

You can set its startup type to manual in services.msc. This way it will not start automatically unless required. Simply get the name of the service from services.msc as shown here:

You can create batch files to start and stop the service fairly easily as well. Now use this name in batch files.

Your start.bat:

net start "mysql"

And in your stop.bat:

net stop "mysql"

I can't find toByteArray() as @atrioom said, so I use StringWriter, please try:

public void writeListToJsonArray() throws IOException {  

    //your list
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));


    final StringWriter sw =new StringWriter();
    final ObjectMapper mapper = new ObjectMapper();
    mapper.writeValue(sw, list);
    System.out.println(sw.toString());//use toString() to convert to JSON

    sw.close(); 
}

Or just use ObjectMapper#writeValueAsString:

    final ObjectMapper mapper = new ObjectMapper();
    System.out.println(mapper.writeValueAsString(list));

What helped me was to register the source directory for jni files in the build.gradle file. Add this to your gradle file:

android {
    sourceSets {
        main {
            jniLibs.srcDir '[YOUR_JNI_DIR]' // i.e. 'libs'
        }
    }
}

I use PowerShell to re-launch the script elevated if it's not. Put these lines at the very top of your script.

net file 1>nul 2>nul && goto :run || powershell -ex unrestricted -Command "Start-Process -Verb RunAs -FilePath '%comspec%' -ArgumentList '/c %~fnx0 %*'"
goto :eof
:run
:: TODO: Put code here that needs elevation

I copied the 'net name' method from @Matt's answer. His answer is much better documented and has error messages and the like. This one has the advantage that PowerShell is already installed and available on Windows 7 and up. No temporary VBScript (*.vbs) files, and you don't have to download tools.

This method should work without any configuration or setup, as long as your PowerShell execution permissions aren't locked down.

All Elements

If developing with your own NuGet server, make sure the assembly versions are all the same:

[assembly: AssemblyVersion("0.2.6")]
[assembly: AssemblyFileVersion("0.2.6")]
[assembly: AssemblyInformationalVersion("0.2.6")]

I used couple of hours trying to figure how to remove background from launched modal, so far tried

.modal-backdrop {    background: none; }

Didn't work even I have tried to work with javascript like

 <script type="text/javascript">   
 $('#modal-id').on('shown.bs.modal',  function () {
       $(".modal-backdrop.in").hide();     })
</script>

Also didn't work either. I just added

data-backdrop="false"

to

<div class="modal fade" id="myModal" data-backdrop="false">......</div>

And Applying css CLASS

.modal {     background-color: transparent !important;  }

Now its working like a charm This worked with Bootstrap 3

When you use EF 6.x code first

    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid Id { get; set; }

and initialize a database table, it will put a

(newsequentialid())

inside the table properties under the header Default Value or Binding, allowing the ID to be populated as it is inserted.

The problem is if you create a table and add the

[DatabaseGenerated(DatabaseGeneratedOption.Identity)]

part later, future update-databases won't add back the (newsequentialid())

To fix the proper way is to wipe migration, delete database and re-migrate... or you can just add (newsequentialid()) into the table designer.

This is easier:

location.href = 'http://address.com';

Or

location.replace('http://address.com'); // <-- No history saved.

If you've checked all the things from the above answers (which are common mistakes) and you're sure that your view is at the location in the exceptions, then you may need to restart Visual Studio.

:(

As RPM1984 refers to, this is mostly likely caused by the fact that your script is loading before jQuery is loaded.

C# code

IWebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((ITakesScreenshot)driver).GetScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

I think the answer is here now : https://bugs.mysql.com/bug.php?id=83822

So, you should write :

GRANT ALL PRIVILEGES ON mydb.* to myuser@'xxx.xxx.xxx.xxx' IDENTIFIED BY 'mypassword';

And i think that could be work :

SET PASSWORD FOR myuser@'xxx.xxx.xxx.xxx' IDENTIFIED BY 'old_password' = PASSWORD('new_password');

There is an operator in C called the comma operator. It executes each expression in order and returns the value of the last statement. It's also a sequence point, meaning each expression is guaranteed to execute in completely and in order before the next expression in the series executes, similar to && or ||.

This is a simple fix. Open the project you are getting this error on. Click "Project" at the top. Then click " Properties" ( Will be the name of the opened project) then click "Security" then uncheck "Enable ClickOnce security settings."

That should fix everything.

:%s/string/string/g will give the answer.

I have faced with the same issue on Ubuntu(both local.properties and ANDROID_HOME was added), but build fail persisted. So workaround is to add following lines

export ANDROID_HOME=/home/<user>/Android/Sdk export PATH=$PATH:/home/<user>/Android/Sdk/tools

directly to the studio.sh script (inside /usr/local/android-studio/bin)

Maybe it will be helpful.

You can try this:

        <td class="shrink">element1</td>
        <td class="shrink">data</td>
        <td class="shrink">junk here</td>
        <td class="expand">last column</td>
    </tr>
    <tr>
        <td class="shrink">elem</td>
        <td class="shrink">more data</td>
        <td class="shrink">other stuff</td>
        <td class="expand">again, last column</td>
    </tr>
    <tr>
        <td class="shrink">more</td>
        <td class="shrink">of </td>
        <td class="shrink">these</td>
        <td class="expand">rows</td>
    </tr>
</table>

CSS

table {
    border: 1px solid green;
    border-collapse: collapse;
    width:100%;
}

table td {
    border: 1px solid green;
}

table td.shrink {
    white-space:nowrap
}
table td.expand {
    width: 99%
}

It's a very difficult problem to validate something like a name due to all the corner cases possible.

Corner Cases

• Anything anything here

Sanitize the inputs and let them enter whatever they want for a name, because deciding what is a valid name and what is not is probably way outside the scope of whatever you're doing; given the range of potential strange - and legal names is nearly infinite.

If they want to call themselves Tricyclopltz^2-Glockenschpiel, that's their problem, not yours.

The answers provided are great as long as you only want to handle Arabic numerals, and are working in an encoding where those numerals are sequential, and in the same place as ASCII.

This is almost always the case.

If it isn't then you need a proper library to help you.

Let's start with ICU.

1. First convert the byte-string to a unicode string. (Left as an exercise for the reader).
2. Then use uchar.h to look at each character.
3. if we the character is UBool u_isdigit (UChar32 c)
4. then the value is int32_t u_charDigitValue ( UChar32 c )

Or maybe ICU has some function to do it for you - I haven't looked at it in detail.

I came across a similar situation after publishing a ClickOnce application, and one of my colleagues on a different domain reported that it fails to launch.

To find out what was going on, I added a try catch statement inside the MainWindow method as @BradleyDotNET mentioned in one comment on the original post, and then published again.

public MainWindow()
{
    try
    {
        InitializeComponent();
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.ToString());
    }
}

Then my colleague reported to me the exception detail, and it was a missing reference of a third party framework dll file.

Added the reference and problem solved.

You need to call both clear() from ArrayAdapter and notifyDataSetChanged() both.

I assume you are loading the XML from an external file. With $.ajax(), it's quite simple actually:

$.ajax({
    url: 'xmlfile.xml',
    dataType: 'xml',
    success: function(data){
        // Extract relevant data from XML
        var xml_node = $('Pages',data);
        console.log( xml_node.find('Page[Name="test"] > controls > test').text() );
    },
    error: function(data){
        console.log('Error loading XML data');
    }
});

Also, you should be consistent about the XML node naming. You have both lowercase and capitalized node names (<Page> versus <page>) which can be confusing when you try to use XML tree selectors.

Another way simpler than me has worked with SQL Developer 4 in Windows 7

spool "path_to_file\\filename.txt"
query to execute
spool of

You have to execute it as a script, because if not only the query will be saved in the output file In the path name I use the double character "\" as a separator when working with Windows and SQL, The output file will display the query and the result.

Here is what I am doing to solve this issue. I agree this is because of the timing issue and needed a pause to execute the code.

var delayInMilliseconds = 1000; 
setTimeout(function() {
 //add your code here to execute
 }, delayInMilliseconds);

This new code will pause it for 1 second and meanwhile run your code.

-t: specifies name of JMX file that contains the Test Plan

Once you have you configuration checked and completion is still not working:

• make sure you have the right directory structure.

Do you see the right icon beside the file?:

It will tell you how the file will be treated by Eclipse:

I am posting this answer as I had that story with with Maven webapp artifact. By default Maven-WebApp does not create folder for sources and I put my Java into resources, wondering for 5 minutes what was going on... :)

"Closing" the current iFrame is not possible but you can tell the parent to manipulate the dom and make it invisible.

In IFrame:

parent.closeIFrame();

In parent:

function closeIFrame(){
     $('#youriframeid').remove();
}

Try using the InStr function which returns the index in the string at which the character was found. If InStr returns 0, the string was not found.

If InStr(myString, "A") > 0 Then

InStr MSDN Website

For the error on the line assigning to newStr, convert oldStr.IndexOf to that InStr function also.

Left(oldStr, InStr(oldStr, "A"))

#include? should work, it works for general objects, not only strings. Your problem in example code is this test:

unless @suggested_horses.exists?(horse.id)
  @suggested_horses<< horse
end

(even assuming using #include?). You try to search for specific object, not for id. So it should be like this:

unless @suggested_horses.include?(horse)
  @suggested_horses << horse
end

ActiveRecord has redefined comparision operator for objects to take a look only for its state (new/created) and id

OP wants to decrease brightness, not increase it. Opacity makes the image look brighter, not darker.

You can do this by overlaying a black div over the image and setting the opacity of that div.

<style>
#container {
    position: relative;
}
div.overlay {
    opacity: .9;
    background-color: black;
    position: absolute;
    left: 0; top: 0; height: 256px; width: 256px;
}
</style>

Normal:<br />

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

I'm using the change-case extension and it works fine. I defined the shortcuts:

{ 
  "key": "ctrl+shift+u", 
  "command": "extension.changeCase.upper", 
  "when": "editorTextFocus" 
},
{ 
  "key": "ctrl+u",
  "command": "extension.changeCase.lower", 
  "when": "editorTextFocus" 
},

In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia

In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict) into its valid JSON pendant (object).

• Python's True will be converted to JSONs true and the dictionary itself will then be encapsulated in quotes.
• You can easily spot the difference between a Python dictionary and JSON by their Boolean values:
  • Python: True / False,
  • JSON: true / false
• Python builtin module json is the standard way to do serialization:

Code example:

data = {
    "president": {
        "name": "Zaphod Beeblebrox",
        "species": "Betelgeusian",
        "male": True,
    }
}

import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize

# serialized json_data now looks like:
# {
#   "president": {
#     "name": "Zaphod Beeblebrox",
#     "species": "Betelgeusian",
#     "male": true
#   }
# }

You don't really need a regex.

printf "%s\n" *[!\ -~]*

This will show file names with control characters in their names, too, but I consider that a feature.

If you don't have any matching files, the glob will expand to just itself, unless you have nullglob set. (The expression does not match itself, so technically, this output is unambiguous.)

First give the link of logout.php page in that logout button.In that page make the code which is given below:

Here is the code:

<?php
 session_start();
 session_destroy();
?>

When the session has started, the session for the last/current user has been started, so don't need to declare the username. It will be deleted automatically by the session_destroy method.

The Literal meaning of instance is "an example or single occurrence of something." which is very closer to the Instance in Java terminology.

Java follows dynamic loading, which is not like C language where the all code is copied into the RAM at runtime. Lets capture this with an example.

   class A
    {
    int x=0;
    public static void main(String [] args)    
     {
    int y=0;
    y=y+1;
    x=x+1;
     }   

    }

Let us compile and run this code.

step 1: javac A.class (.class file is generated which is byte code)

step 2: java A (.class file is converted into executable code)

During the step 2,The main method and the static elements are loaded into the RAM for execution. In the above scenario, No issue until the line y=y+1. But whenever x=x+1 is executed, the run time error will be thrown as the JVM does not know what the x is which is declared outside the main method(non-static).

So If by some means the content of .class file is available in the memory for CPU to execute, there is no more issue.

This is done through creating the Object and the keyword NEW does this Job.

"The concept of reserving memory in the RAM for the contents of hard disk (here .class file) at runtime is called Instance "

The Object is also called the instance of the class.

Try this

$objPHPExcel->getActiveSheet()->mergeCells('A1:C1');

yes, if( (A) && (B) ) will fail on the first clause, if (A) evaluates false.

this applies to any language btw, not just C derivatives. For threaded and parallel processing this is a different story ;)

I tried @NorthCat answer using pdfkit.

It required wkhtmltopdf to be installed. The install can be downloaded from here. https://wkhtmltopdf.org/downloads.html

Install the executable file. Then write a line to indicate where wkhtmltopdf is, like below. (referenced from Can't create pdf using python PDFKIT Error : " No wkhtmltopdf executable found:"

import pdfkit


path_wkthmltopdf = "C:\\Folder\\where\\wkhtmltopdf.exe"
config = pdfkit.configuration(wkhtmltopdf = path_wkthmltopdf)

pdfkit.from_url("http://google.com", "out.pdf", configuration=config)

Try this very simple approach:

/*make sure that value is included in the options value of the dropdownlist 
e.g. 
(<select><option value='CA'>California</option><option value='AK'>Alaska</option>      </select>)
*/

$('#mycontrolId').val(myvalue).attr("selected", "selected");

If anyone else is stuck on this,

nothing of the above worked for me. I had to remove

implementation group: "ch.qos.logback", name: "logback-classic", version: "1.2.3"
implementation group: 'com.typesafe.scala-logging', name: "scala-logging_$scalaVersion", version: '3.9.2'

from my build.gradle for the logs to disappear. TLDR: Don't import any other logging frameworks, you should be fine just using org.apache.log4j.Logger

Quick and dirty:

LP == Long Pointer. Just think pointer or char*

C = Const, in this case, I think they mean the character string is a const, not the pointer being const.

STR is string

the T is for a wide character or char (TCHAR) depending on compile options.

Steps to resolve this issue 1.Right click on your project 2.Click on validate option

Result :TODO issue resolved

For HTML5, you can use the 'hidden' attribute.

<option hidden>Hidden option</option>

It is not supported by IE < 11. But if you need only to hide a few elements, maybe it would be better to just set the hidden attribute in combination with disabled in comparison to adding/removing elements or doing not semantically correct constructions.

<select>  _x000D_
  <option>Option1</option>_x000D_
  <option>Option2</option>_x000D_
  <option hidden>Hidden Option</option>_x000D_
</select>

Reference.

This will give you duplicate rows:

vocabulary[duplicated(vocabulary$id),]

This will give you the number of duplicates:

dim(vocabulary[duplicated(vocabulary$id),])[1]

Example:

vocabulary2 <-rbind(vocabulary,vocabulary[1,]) #creates a duplicate at the end
vocabulary2[duplicated(vocabulary2$id),]
#            id year    sex education vocabulary
#21639 20040001 2004 Female         9          3
dim(vocabulary2[duplicated(vocabulary2$id),])[1]
#[1] 1 #=1 duplicate

EDIT

OK, with the additional information, here's what you should do: duplicated has a fromLast option which allows you to get duplicates from the end. If you combine this with the normal duplicated, you get all duplicates. The following example adds duplicates to the original vocabulary object (line 1 is duplicated twice and line 5 is duplicated once). I then use table to get the total number of duplicates per ID.

#Create vocabulary object with duplicates
voc.dups <-rbind(vocabulary,vocabulary[1,],vocabulary[1,],vocabulary[5,])

#List duplicates
dups <-voc.dups[duplicated(voc.dups$id)|duplicated(voc.dups$id, fromLast=TRUE),]
dups
#            id year    sex education vocabulary
#1     20040001 2004 Female         9          3
#5     20040008 2004   Male        14          1
#21639 20040001 2004 Female         9          3
#21640 20040001 2004 Female         9          3
#51000 20040008 2004   Male        14          1

#Count duplicates by id
table(dups$id)
#20040001 20040008 
#       3        2 

You can also make sure you run the Command Prompt - or whatever terminal you use - As Administrator. I am using Visual Studio Code and the ng serve command gives me that exact error when not running VS Code as admin.

You can use like this:

import os
from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello():
     # Redirect from here, replace your custom site url "www.google.com"
    return redirect("https://www.google.com", code=200)

if __name__ == '__main__':
    # Bind to PORT if defined, otherwise default to 5000.
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

Here is the referenced link to this code.

Use extension methods. Replace NameOfContext with the name of your object context.

public static class Extensions{
   public static IQueryable<Company> CompleteCompanies(this NameOfContext context){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country") ;
     }

     public static Company CompanyById(this NameOfContext context, int companyID){
         return context.Companies
             .Include("Employee.Employee_Car")
             .Include("Employee.Employee_Country")
             .FirstOrDefault(c => c.Id == companyID) ;
      }

}

Then your code becomes

     Company company = 
          context.CompleteCompanies().FirstOrDefault(c => c.Id == companyID);

     //or if you want even more
     Company company = 
          context.CompanyById(companyID);

I have developed a double Splitter (Takes two split characters) as requested Here. Could be of some value in this thread seeing its the most referenced for queries relating to string splitting.

            NULL AS SecondarySplitID,
            SValue
       FROM @FResult

RETURN

Usage:

--FirstSplit
SELECT * FROM uft_DoubleSplitter('ValueA=ValueB=ValueC=ValueD==ValueE&ValueA=ValueB=ValueC===ValueE&ValueA=ValueB==ValueD===','&',NULL)

--Second Split
SELECT * FROM uft_DoubleSplitter('ValueA=ValueB=ValueC=ValueD==ValueE&ValueA=ValueB=ValueC===ValueE&ValueA=ValueB==ValueD===','&','=')

Possible Usage (Get second value of each split):

SELECT fn.SValue
FROM uft_DoubleSplitter('ValueA=ValueB=ValueC=ValueD==ValueE&ValueA=ValueB=ValueC===ValueE&ValueA=ValueB==ValueD===', '&', '=')AS fn
WHERE fn.mid = 2

While I appreciate you believe absolute paths is not an option, it is a better option than relative paths and updating the PHP include path.

Use absolute paths with an constant you can set based on environment.

if (is_production()) {
    define('ROOT_PATH', '/some/production/path');
}
else {
    define('ROOT_PATH', '/root');
}

include ROOT_PATH . '/connect.php';

As commented, ROOT_PATH could also be derived from the current path, $_SERVER['DOCUMENT_ROOT'], etc.

I know this has been answered with a very high-quality answer. But, in short, you cant have spaces.

#!/bin/bash
STR = "Hello World"
echo $STR

Didn't work because of the spaces around the equal sign. If you were to run...

#!/bin/bash
STR="Hello World"
echo $STR

It would work

In this case you should add .clearfix at the end of container with floated elements.

        <a href="#" class="btn btn-default btn-sm">## Move</a>
    </div>
    <span class="clearfix"></span>

I wanted to provide with a solution inspired by physics.

Imagine a force applied along the line and you are measuring the torque of the force about the point. If the torque is positive (counterclockwise) then the point is to the "left" of the line, but if the torque is negative the point is the "right" of the line.

So if the force vector equals the span of the two points defining the line

fx = x_2 - x_1
fy = y_2 - y_1

you test for the side of a point (px,py) based on the sign of the following test

var torque = fx*(py-y_1)-fy*(px-x_1)
if  torque>0  then
     "point on left side"
else if torque <0 then
     "point on right side"  
else
     "point on line"
end if

Try this

Using Classes in Node -

Here we are requiring the ReadWrite module and calling a makeObject(), which returns the object of the ReadWrite class. Which we are using to call the methods. index.js

const ReadWrite = require('./ReadWrite').makeObject();
const express = require('express');
const app = express();

class Start {
  constructor() {
    const server = app.listen(8081),
     host = server.address().address,
     port = server.address().port
    console.log("Example app listening at http://%s:%s", host, port);
    console.log('Running');

  }

  async route(req, res, next) {
    const result = await ReadWrite.readWrite();
    res.send(result);
  }
}

const obj1 = new Start();
app.get('/', obj1.route);
module.exports = Start;

ReadWrite.js

Here we making a makeObject method, which makes sure that a object is returned, only if a object is not available.

class ReadWrite {
    constructor() {
        console.log('Read Write'); 
        this.x;   
    }
    static makeObject() {        
        if (!this.x) {
            this.x = new ReadWrite();
        }
        return this.x;
    }
    read(){
    return "read"
    }

    write(){
        return "write"
    }


    async readWrite() {
        try {
            const obj = ReadWrite.makeObject();
            const result = await Promise.all([ obj.read(), obj.write()])
            console.log(result);
            check();
            return result
        }
        catch(err) {

    }
}

You need to put the data before render

Should be like this:

var data = [
  {author: "Pete Hunt", text: "This is one comment"},
  {author: "Jordan Walke", text: "This is *another* comment"}
];

React.render(
  <CommentBox data={data}/>,
  document.getElementById('content')
);

Instead of this:

React.render(
  <CommentBox data={data}/>,
  document.getElementById('content')
);

var data = [
  {author: "Pete Hunt", text: "This is one comment"},
  {author: "Jordan Walke", text: "This is *another* comment"}
];

Using with FILEPATH option might work:

set(CMAKE_CXX_COMPILER:FILEPATH C:/MinGW/bin/gcc.exe)

Installing CuDNN just involves placing the files in the CUDA directory. If you have specified the routes and the CuDNN option correctly while installing caffe it will be compiled with CuDNN.

You can check that using cmake. Create a directory caffe/build and run cmake .. from there. If the configuration is correct you will see these lines:

-- Found cuDNN (include: /usr/local/cuda-7.0/include, library: /usr/local/cuda-7.0/lib64/libcudnn.so)

-- NVIDIA CUDA:
--   Target GPU(s)     :   Auto
--   GPU arch(s)       :   sm_30
--   cuDNN             :   Yes

If everything is correct just run the make orders to install caffe from there.

This answer didn't work for me, but I found the answer myself. No one, however, has posted my question. I'm too lazy to ask it and then answer it, so will just put it here.

This is for the following query:

data = Leaderboard.objects.filter(id=custom_user.id).values(
    'value1',
    'value2',
    'value3')

In template:

{% for dictionary in data %}
  {% for key, value in dictionary.items %}
    <p>{{ key }} : {{ value }}</p>
  {% endfor %}
{% endfor %}

Just pieced this together for the same problem:

before_filter :validate_params

private

def validate_params
  return head :bad_request unless params_present?
end

def params_present?  
  Set.new(%w(one two three)) <= (Set.new(params.keys)) &&
  params.values.all?
end

the first line checks if our target keys are present in the params' keys using the <= subset? operator. Enumerable.all? without block per default returns false if any value is nil or false.

$(document).ready(function() {
            
   var url = window.location.href;
            
   $('a[href*="'+url+'"]').addClass("active");
            
});

The basic difference :

Linear regression is basically a regression model which means its will give a non discreet/continuous output of a function. So this approach gives the value. For example : given x what is f(x)

For example given a training set of different factors and the price of a property after training we can provide the required factors to determine what will be the property price.

Logistic regression is basically a binary classification algorithm which means that here there will be discreet valued output for the function . For example : for a given x if f(x)>threshold classify it to be 1 else classify it to be 0.

For example given a set of brain tumour size as training data we can use the size as input to determine whether its a benine or malignant tumour. Therefore here the output is discreet either 0 or 1.

*here the function is basically the hypothesis function

Complementing the previous answers, one big difference between both is that Visual Studio Code comes in a so called "portable" version that does not require full administrative permissions to run on Windows and can be placed in a removable drive for convenience.

Yes, but note: since the attribute selector (of course) targets the element's attribute, not the DOM node's value property (elem.value), it will not update while the form field is being updated.

Otherwise (with some trickery) I think it could have been used to make a CSS-only substitute for the "placeholder" attribute/functionality. Maybe that's what the OP was after? :)

You can directly check the version with one line only by invoking PowerShell externally, such as from Command Prompt

powershell -Command "$PSVersionTable.PSVersion"

According to @psaul you can actually have one command that is agnostic from where it came (CMD, PowerShell or Pwsh). Thank you for that.

powershell -command "(Get-Variable PSVersionTable -ValueOnly).PSVersion"

I've tested and it worked flawlessly on both CMD and PowerShell.

=Sum(C:C)-Sum(C1:C5)

Sum everything then remove the sum of the values in the cells you don't want, no Volatile Offset's, Indirect's, or Array's needed.

Just for fun if you don't like that method you could also use:

=SUM($C$6:INDEX($C:$C,MATCH(9.99999999999999E+307,$C:$C))

The above formula will Sum only from C6 through the last cell in C:C where a match of a number is found. This is also non-volatile, but I believe more costly and sloppy. Just added it in case you'd prefer this anyways.

If you would like to do function like CountA for text using the last text value in a column you could use.

=COUNTIF(C6:INDEX($C:$C,MATCH(REPT("Z",255),$C:$C)),"T")

you could also use other combinations like:

=Sum($C$6:$C$65536) 

or

=CountIF($C$6:$C$65536,"T") 

The above would do what you ask in Excel 2003 and lower

=Sum($C$6:$C$1048576) 

or

=CountIF($C$6:$C$1048576,"T")

Would both work for Excel 2007+

All above functions would simply ignore all the blank values under the last value.

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

This code was adapted from Ozgrid

and as jkf points out, from Mr Excel

It's not possible to change web-kit browsers use user's computer or mobiles default date format. But if you can use jquery and jquery UI there is a date-picker which is designable and can be shown in any format as the developer wants. the link to the jquery UI date-picker is on this page http://jqueryui.com/datepicker/ you can find demo as well as code and documentation or documentation link

Edit:-I find that chrome uses language settings that are by default equal to system settings but the user can change them but developer can't force users to do so so you have to use other js solutions like I tell you can search the web with queries like javascript date-pickers or jquery date-picker

After I stopped banging my head on the desk thinking of the entire week I spent running down this problem, I am sharing what worked for me. I have Win7 64 bit, 32-bit Oracle Client, and have my MVC 5 project set to run on x86 platform because of the Oracle bitness. I kept getting the same errors:

Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.

I reloaded the NuGet packages, I used copies of the DLLs that worked for others in different apps, I set the codebase in the dependent assembly to point to my project's bin folder, I tried CopyLocal as true or false, I tried everything. Finally I had enough else done I wanted to check in my code, and as a new contractor I didn't have subversion set up. While looking for a way to hook it into VS, I tripped over the answer. What I found worked was unchecking the "Use the 64 bit version of IIS Express for Web Sites and Projects" option under the Projects and Solutions => Web Projects section under the Tools=>Options menu.

Using .NET 3.5 FIX

All of you are slightly wrong, but the combination of all of your efforts has paid off!

Instead of eval('([' + jsonData + '])'); do

success: function(msg){
var data = eval(msg.d);
var i=0;
for(i=0;i<data.length;i++){
    data[i].parametername /// do whatever you want here.
};

I don't know anything about the whole "don't use eval," but what I do know is that by doing the '([' + msg + '])' you are nesting those objects deeper, instead of up a level.

This javascript is nice that it doesn't open a new window or tab.

window.location.assign(url);

It sets the default collation for the table; if you create a new column, that should be collated with latin_general_ci -- I think. Try specifying the collation for the individual column and see if that works. MySQL has some really bizarre behavior in regards to the way it handles this.

Coordinating access to a single file at the OS level is fraught with all kinds of issues that you probably don't want to solve.

Your best bet is have a separate process that coordinates read/write access to that file.

Here is a function I used to remove all possible special characters from the string

let name = name.replace(/[&\/\\#,+()$~%!.„'":*‚^_¤?<>|@ª{«»§}©®™ ]/g, '').toLowerCase();

For older git versions (1.8 and before)

I could find no suitable way to enable SSH debugging in an older git and ssh versions. I looked for environment variables using ltrace -e getenv ... and couldn't find any combination of GIT_TRACE or SSH_DEBUG variables that would work.

Instead here's a recipe to temporarily inject 'ssh -v' into the git->ssh sequence:

$ echo '/usr/bin/ssh -v ${@}' >/tmp/ssh
$ chmod +x /tmp/ssh
$ PATH=/tmp:${PATH} git clone ...
$ rm -f /tmp/ssh

I had a similar problem: In my test-cases executions I always got this error. I found out, that my "Distributed Transaction Service" was not started (run: services.msc -> start "Distributed Transaction Service" (best to set it to start automatic)). After I did that, it worked like a charm...

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

You could use cat file.txt | head -1, but it would probably be better to use head directly, as in head -1 file.txt.

This was the good option for SEO because SEO gives the H1 tag high priority, inside the h1 tag should be your site name. Using this method if you search the site name in SEO it will show your site logo as well.

you want to hide the site name OR text please use text-indent in negative value. ex

h1 a {
 text-indent: -99999px;
}

No you cannot. The only thing you can do is to insert content. Like so:

p:after {
    content: "yo";
}

x(end+1) = newElem is a bit more robust.

x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem, however, works for both row- and column-vectors.

In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)

I would put an absolutely positioned, z-index: 100; span (or spans) with the background: url("myImageWithRoundedCorners.jpg"); set on it inside the #mainWrapperDivWithBGImage .

An other way:

Add library in the tree view. Right click on this one. Select menu "Add As Library". A dialog appear, let you select module. OK and it's done.

bool Square::IsOverlappig(Square &other)
{
    bool result1 = other.x >= x && other.y >= y && other.x <= (x + width) && other.y <= (y + height); // other's top left falls within this area
    bool result2 = other.x >= x && other.y <= y && other.x <= (x + width) && (other.y + other.height) <= (y + height); // other's bottom left falls within this area
    bool result3 = other.x <= x && other.y >= y && (other.x + other.width) <= (x + width) && other.y <= (y + height); // other's top right falls within this area
    bool result4 = other.x <= x && other.y <= y && (other.x + other.width) >= x && (other.y + other.height) >= y; // other's bottom right falls within this area
    return result1 | result2 | result3 | result4;
}

You can use array_walk_recursive() to get a general-case solution for your problem (the one when each inner array can possibly have unique keys).

$final = array();

array_walk_recursive($input, function($item, $key) use (&$final){
    $final[$key] = isset($final[$key]) ?  $item + $final[$key] : $item;
});

Example with array_walk_recursive() for the general case

Also, since PHP 5.5 you can use the array_column() function to achieve the result you want for the exact key, [gozhi], for example :

array_sum(array_column($input, 'gozhi')); 

Example with array_column() for the specified key

If you want to get the total sum of all inner arrays with the same keys (the desired result that you've posted), you can do something like this (bearing in mind that the first inner array must have the same structure as the others) :

$final = array_shift($input);

foreach ($final as $key => &$value){
   $value += array_sum(array_column($input, $key));
}    

unset($value);

Example with array_column() in case all inner arrays have the same keys

If you want a general-case solution using array_column() then at first you may consider to get all unique keys , and then get the sum for each key :

$final = array();

foreach($input as $value)
    $final = array_merge($final, $value);

foreach($final as $key => &$value)
    $value = array_sum(array_column($input, $key));

unset($value);

Example with array_column() for the general case

There are several options and none of them are the official correct way and none of them are really incorrect, though they can convey different information to the computer and to others reading your code.

For the given example I think the clearest option would be to supply an identity default value, in this case do something like:

fooBar <- function(x, y=0) {
  x + y
}

This is the shortest of the options shown so far and shortness can help readability (and sometimes even speed in execution). It is clear that what is being returned is the sum of x and y and you can see that y is not given a value that it will be 0 which when added to x will just result in x. Obviously if something more complicated than addition is used then a different identity value will be needed (if one exists).

One thing I really like about this approach is that it is clear what the default value is when using the args function, or even looking at the help file (you don't need to scroll down to the details, it is right there in the usage).

The drawback to this method is when the default value is complex (requiring multiple lines of code), then it would probably reduce readability to try to put all that into the default value and the missing or NULL approaches become much more reasonable.

Some of the other differences between the methods will appear when the parameter is being passed down to another function, or when using the match.call or sys.call functions.

So I guess the "correct" method depends on what you plan to do with that particular argument and what information you want to convey to readers of your code.

string root = HttpContext.Current.Server.MapPath("~/App_Data");

I recommend always using a named range (as you have suggested you are doing) because if any columns or rows are added or deleted, the name reference will update, whereas if you hard code the cell reference (eg "H1" as suggested in one of the responses) in VBA, then it will not update and will point to the wrong cell.

So

Range("RefNo") = InputBox("....") 

is safer than

Range("H1") = InputBox("....") 

You can set the value of several cells, too.

Range("Results").Resize(10,3) = arrResults()

where arrResults is an array of at least 10 rows & 3 columns (and can be any type). If you use this, put this

Option Base 1

at the top of the VBA module, otherwise VBA will assume the array starts at 0 and put a blank first row and column in the sheet. This line makes all arrays start at 1 as a default (which may be abnormal in most languages but works well with spreadsheets).

$('document').ready(function () {
    $("#imgload").change(function () {
        if (this.files && this.files[0]) {
            var reader = new FileReader();
            reader.onload = function (e) {
                $('#imgshow').attr('src', e.target.result);
            }
            reader.readAsDataURL(this.files[0]);
        }
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="file" id="imgload" >
<img src="#" id="imgshow" align="left">

That works for me in jQuery.

You could break by RETURN. For example

  def a = [1, 2, 3, 4, 5, 6, 7]
  def ret = 0
  a.each {def n ->
    if (n > 5) {
      ret = n
      return ret
    }
  }

It works for me!

Ensure the user that is executing the git pull is the same user that created the repository. The file permissions are incorrect.

I didn't get the interrupt to work in Android, so I used this method, works perfectly:

boolean shouldCheckUpdates = true;

private void startupCheckForUpdatesEveryFewSeconds() {
    threadCheckChat = new Thread(new CheckUpdates());
    threadCheckChat.start();
}

private class CheckUpdates implements Runnable{
    public void run() {
        while (shouldCheckUpdates){
            System.out.println("Do your thing here");
        }
    }
}

 public void stop(){
        shouldCheckUpdates = false;
 }

You can use the .Clear method:

Sheets("Zeros").UsedRange.Clear

Using this you can remove the contents and the formatting of a cell or range without affecting the rest of the worksheet.

I used the data from Shawn's answer but generalized and shortened the regex a little. The key difference with this one is that it won't test for a valid Youtube URL, it'll just look for a video ID. Meaning it will still return a video ID for www.facebook.com?wtv=youtube.com/v/vidid. Works for all the test cases, but is a bit more lax. Consequently, it will output a false positive for something like https://www.twitter.com/watch?v=vidid. Use this method if the data is super inconsistent, otherwise use a more specific regex or parse_url() and parse_str().

preg_match("/([\?&\/]vi?|embed|\.be)[\/=]([\w-]+)/",$url,$matches);
print($matches[2]);

attr accepts two strings.

The correct way is:

jQuery("#radio_1").attr('checked', 'true');

Angular Reactive Forms:

onCancel(): void {
  this.registrationForm.reset();
  this.registrationForm.controls['name'].setErrors(null);
  this.registrationForm.controls['email'].setErrors(null);
}

As a reflex answer, I would recommend using rem, because it allows you to change the "zoom level" of the whole document at once, if necessary. In some cases, when you want the size to be relative to the parent element, then use em.

But rem support is spotty, IE8 needs a polyfill, and Webkit is exhibiting a bug. Moreover, sub-pixel calculation can cause things such as one pixel lines to sometimes disappear. The remedy is to code in pixels for such very small elements. That introduces even more complexity.

So, overall, ask yourself whether it's worth it - how important and likely it is that you change the "zoom level" of the whole document within CSS?

For some cases it's yes, for some cases it'll be no.

So, it depends on your needs, and you have to weight pros and cons, because using rem and em introduces some additional considerations in comparison to the "normal" pixel-based workflow.

Keep in mind that it's easy to switch (or rather convert) your CSS from px to rem (JavaScript is another story), because the following two blocks of CSS code would produce the same result:

html {
}

body {
  font-size:14px;
}

.someElement {
  width: 12px;
}

html {
  font-size:1px;
}

body {
  font-size:14rem;
}

.someElement {
  width: 12rem;
}

//LinearLayOut Setup
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

linearLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));

//ImageView Setup
ImageView imageView = new ImageView(this);

//setting image resource
imageView.setImageResource(R.drawable.play);

//setting image position
imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 
LayoutParams.WRAP_CONTENT));

//adding view to layout
linearLayout.addView(imageView);
//make visible to program
setContentView(linearLayout);

The default password is empty. More accurately, you don't even NEED a password to login as root on the localhost. You just need to BE root. But if you need to set the password the first time (if you allow remote access to root), you need to use:

sudo mysql_secure_installation

Enter empty password, then follow the instructions.

The problem you are having is that you need to BE root when you try to login as root from the local machine.

On Linux: mariadb will accept a connection as root on the socket (localhost) ONLY IF THE USER ASKING IT IS ROOT. Which means that even if you try

mysql -u root -p

And have the correct password you will be refused access. Same goes for

mysql_secure_installation

Mariadb will always refuse the password because the current user is not root. So you need to call them with sudo (or as the root user on your machine) So locally you just want to use:

sudo mysql

and

sudo mysql_secure_installation

When moving from mysql to mariadb it took I will for me to figure this out.

This is from antiquated technology: The old fashion typewriter style of printer. There was a roller (platen) that advanced the paper and a print head that hammered a metal key against an ink fabric.

\r Return the print head to the left side.

\n Advance the platen one line.

If the \n was not issued, you would type over what was on a line (used mostly for underlining text).

Great question!

There are many websites and free web apps implemented in PHP that run on Apache, lots of people use it so you can mash up something pretty easy and besides, its a no-brainer way of serving static content. Node is fast, powerful, elegant, and a sexy tool with the raw power of V8 and a flat stack with no in-built dependencies.

I also want the ease/flexibility of Apache and yet the grunt and elegance of Node.JS, why can't I have both?

Fortunately with the ProxyPass directive in the Apache httpd.conf its not too hard to pipe all requests on a particular URL to your Node.JS application.

ProxyPass /node http://localhost:8000

Also, make sure the following lines are NOT commented out so you get the right proxy and submodule to reroute http requests:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then run your Node app on port 8000!

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello Apache!\n');
}).listen(8000, '127.0.0.1');

Then you can access all Node.JS logic using the /node/ path on your url, the rest of the website can be left to Apache to host your existing PHP pages:

Now the only thing left is convincing your hosting company let your run with this configuration!!!

feedgnuplot is another front end to gnuplot, which handles piping in data.

    $ seq 5 | awk '{print 2*$1, $1*$1}' |
      feedgnuplot --lines --points --legend 0 "data 0" --title "Test plot" --y2 1
                  --terminal 'dumb 80,40' --exit

                                     Test plot

For Laravel 5.x we can redirect with just

return redirect()->to($url);

I had the same problem and solved with '%' operator:

select 12.54 % 1;

There's no need to use a lambda, when you can remove all the null ones, and put one back if the input size changes:

input = [Object(name=""), Object(name="fake_name"), Object(name="")] 
output = [x for x in input if x.name]
if(len(input) != len(output)):
    output.append(Object(name=""))

In addition to Telmo Marques answer: I use Virtual Router for this.

Like connectify it creates an accesspoint on your Windows 8, Windows 7 or 2008 R2 machine, but it's open-source.

Here is the script... 

#!/bin/bash
echo "Please enter username:"
read username
echo "Please enter the new password:"
read -s password1
echo "Please repeat the new password:"
read -s password2

# Check both passwords match
if [ $password1 != $password2 ]; then
echo "Passwords do not match"
 exit    
fi

# Does User exist?
id $username &> /dev/null
if [ $? -eq 0 ]; then
echo "$username exists... changing password."
else
echo "$username does not exist - Password could not be updated for $username"; exit 
fi

# Change password
echo -e "$password1\n$password1" | passwd $username

Refer the link below as well...

http://www.putorius.net/2013/04/bash-script-to-change-users-password.html

$(document).ready(function(){

    $('.container').each(function(){  
        var highestBox = 0;

        $(this).find('.column').each(function(){
            if($(this).height() > highestBox){  
                highestBox = $(this).height();  
            }
        })

        $(this).find('.column').height(highestBox);
    });    


});

If the schema of id is not of type ObjectId you cannot operate with function : findbyId()

There's, however, slight difference among all these options which

I found out that

If you do

    string URL = Server.MapPath("~");

or

    string URL = Server.MapPath("/");

or

    string URL = HttpRuntime.AppDomainAppPath;

your URL will display resources in your link like this:

    "file:///d:/InetPUB/HOME/Index/bin/Resources/HandlerDoc.htm"

But if you want your URL to show only virtual path not the resources location, you should do

    string URL = HttpRuntime.AppDomainAppVirtualPath; 

then, your URL is displaying a virtual path to your resources as below

    "http://HOME/Index/bin/Resources/HandlerDoc.htm"        

Support for OFFSET and LIMIT was recently added to DB2 for i 7.1 and 7.2. You need the following DB PTF group levels to get this support:

• SF99702 level 9 for IBM i 7.2
• SF99701 level 38 for IBM i 7.1

See here for more information: OFFSET and LIMIT documentation, DB2 for i Enhancement Wiki

A common reason occurs is if you don't also load jqueryui after loading jquery.

For example:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" type="text/javascript"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js" type="text/javascript"></script>

EDIT. Replace the version number for each library with appropriate or latest values for jquery and jqueryui.

If this doesn't solve the issue, review suggestions in the many other answers.

Use __new__ when you need to control the creation of a new instance.

Use __init__ when you need to control initialization of a new instance.

__new__ is the first step of instance creation. It's called first, and is responsible for returning a new instance of your class.

In contrast, __init__ doesn't return anything; it's only responsible for initializing the instance after it's been created.

In general, you shouldn't need to override __new__ unless you're subclassing an immutable type like str, int, unicode or tuple.

From April 2008 post: When to use __new__ vs. __init__? on mail.python.org.

You should consider that what you are trying to do is usually done with a Factory and that's the best way to do it. Using __new__ is not a good clean solution so please consider the usage of a factory. Here you have a good factory example.

If you want to set a max width or height (so that it will not be very large) while keeping the images aspect-ratio, you can do this:

img{
   object-fit: contain;
   max-height: 70px;
}

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

There is no such function; the easiest way to do this is to use a dict comprehension:

my_dictionary = {k: f(v) for k, v in my_dictionary.items()}

In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn't introduced until python 2.7.

Note that there is no such method on lists either; you'd have to use a list comprehension or the map() function.

As such, you could use the map() function for processing your dict as well:

my_dictionary = dict(map(lambda kv: (kv[0], f(kv[1])), my_dictionary.iteritems()))

but that's not that readable, really.

I have just solved the same issue upon setting up my Windows 8.1 PC. Exactly like @George Papatheodorou mentioned above (sorry I cannot add a comment), Eclipse and JRE must be both 64 bit or 32 bit.

However, it seems for Windows 8/8.1 environment, you are going to get 32-bit JRE by default (and I do not know where to change that default for the download), as explained here: http://java.com/en/download/faq/win8_faq.xml

I was using 64-bit Eclipse so there was a discrepancy. I then installed 32-bit Eclipse and everything works fine this time.

So before bothering changing any environment variables, check your JRE and Eclipse version.

Of course you can use 64-bit JRE with 64-bit Eclipse. Just make sure they match because Windows 8.1 will give you 32-bit by default.

import json

list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

Write to json File:

with open('/home/ubuntu/test.json', 'w') as fout:
    json.dump(list , fout)

Read Json file:

with open(r"/home/ubuntu/test.json", "r") as read_file:
    data = json.load(read_file)
print(data)
#list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

One thing you can do is to set your axis range by yourself by using matplotlib.pyplot.axis.

matplotlib.pyplot.axis

from matplotlib import pyplot as plt
plt.axis([0, 10, 0, 20])

0,10 is for x axis range. 0,20 is for y axis range.

or you can also use matplotlib.pyplot.xlim or matplotlib.pyplot.ylim

matplotlib.pyplot.ylim

plt.ylim(-2, 2)
plt.xlim(0,10)

Make sure that you have the child class explicitly inherit the parent class:

public class Ext : Base { // stuff }

Try with this code:

InputStream in = address.openStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder result = new StringBuilder();
String line;
while((line = reader.readLine()) != null) {
    result.append(line);
}
System.out.println(result.toString());

I know this question already has a chosen answer, but I found this article that evidently shows that string interpolation works faster than concatenation. It might be helpful for those who are still in doubt.

Try this:

$(":focus").each(function() {
    alert("Focused Elem_id = "+ this.id );
});

You can use the DataGridView refresh method. But... in a lot of cases you have to refresh the DataGridView from methods running on a different thread than the one where the DataGridView is running. In order to do that you should implement the following method and call it rather than directly typing DataGridView.Refresh():

    private void RefreshGridView()
    {
        if (dataGridView1.InvokeRequired)
        {
            dataGridView1.Invoke((MethodInvoker)delegate ()
            {
                RefreshGridView();
            });
        }
        else
            dataGridView1.Refresh();
    }  

Have you thinked about using instanceof ? Like, say

if(myObject instanceof Collection) {
     Collection myCollection = (Collection) myObject;

Although not that pure OOP style, it is however largely used for so-called "type escalation".

Very easy, actually.

VB.NET:

Private Function SplitOnNewLine(input as String) As String
    Return input.Split(Environment.NewLine)
End Function

C#:

string splitOnNewLine(string input)
{
    return input.split(environment.newline);
}

Problem

While the pattern for testing multiple values

>>> 2 in {1, 2, 3}
True
>>> 5 in {1, 2, 3}
False

is very readable and is working in many situation, there is one pitfall:

>>> 0 in {True, False}
True

But we want to have

>>> (0 is True) or (0 is False)
False

Solution

One generalization of the previous expression is based on the answer from ytpillai:

>>> any([0 is True, 0 is False])
False

which can be written as

>>> any(0 is item for item in (True, False))
False

While this expression returns the right result it is not as readable as the first expression :-(

Shorter than accepted A, easily extensible and addresses 0 and below:

=if(or(A2<=0,A2>2000),"?",if(A2<500,"Less than 500","Between "&500*int(A2/500)&" and "&500*(int(A2/500)+1))) 

You will need to make sure that if you're using a test environment like WAMP set your username as root. Here is an example which connects to a MySQL database, issues your query, and outputs <option> tags for a <select> box from each row in the table.

<?php

mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT PcID FROM PC";
$result = mysql_query($sql);

echo "<select name='PcID'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['PcID'] . "'>" . $row['PcID'] . "</option>";
}
echo "</select>";

?>

Click on the file and hover on Preferences. there you will find the first option as Settings and click on that. There search run code. and scroll and find the option code runner: Run in Terminal. now check the option below it

Have you tried using Unix style slashes (/ instead of \)?

\ is often an escape or command character, and may be the source of confusion. I have never had issues with this, but I also do not have Windows, so I cannot test it.

Additionally, the permissions may be based on the user running psql, or maybe the user executing the postmaster service, check that both have read to that file in that directory.

You can also use unionBy for 4.0.0 and later, as follows: let uniques = _.unionBy(data, 'id')

On windows:

chrome --allow-file-access-from-files file:///C:/test%20-%203.html

On linux:

google-chrome --allow-file-access-from-files file:///C:/test%20-%203.html

Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(this);

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    if(v.getId() == R.id.button1){
        Toast.makeText(context, "Button 1 Click", Toast.LENGTH_LONG).show();
    }
}

Personally I extract the POST array and then have if(!$login || !$password) then echo fill out the form :)

I just closed all the files and reopened them, and voila!!! Hope this helps someone in the future ;)

SlowCheetah and FastKoala from the VisualStudio Gallery seem to be very good tools that help out with this problem.

However, if you want to avoid addins or use the principles they implement more extensively throughout your build/integration processes then adding this to your msbuild *proj files is a shorthand fix.

Note: this is more or less a rework of the No. 2 of @oleksii's answer.

This works for .exe and .dll projects:

  <Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
  </Target>

This works for web projects:

  <Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
  </Target>

Note that this step happens even before the build proper begins. The transformation of the config file happens in the project folder. So that the transformed web.config is available when you are debugging (a drawback of SlowCheetah).

Do remember that if you create the App_Config folder (or whatever you choose to call it), the various intermediate config files should have a Build Action = None, and Copy to Output Directory = Do not copy.

This combines both options into one block. The appropriate one is executed based on conditions. The TransformXml task is defined first though:

<Project>
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="TransformOnBuild" BeforeTargets="PrepareForBuild">
    <TransformXml Condition="Exists('App_Config\app.Base.config')" Source="App_Config\app.Base.config" Transform="App_Config\app.$(Configuration).config" Destination="app.config" />
    <TransformXml Condition="Exists('App_Config\Web.Base.config')" Source="App_Config\Web.Base.config" Transform="App_Config\Web.$(Configuration).config" Destination="Web.config" />
</Target>

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

import psycopg2
connection_psql = psycopg2.connect( user="admin_user"
                                  , password="***"
                                  , port="5432"
                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

Using

public String replaceAll(String regex, String replacement)

will work.

Usage would be str.replace("X", "");.

Executing

"Xlakjsdf Xxx".replaceAll("X", "");

returns:

lakjsdf xx

npm install -g npm@4

This will install the latest version on the major release 4, no no need to specify version number. Replace 4 with whatever major release you want.

Use .splice to remove item from array. Using delete, indexes of the array will not be altered but the value of specific index will be undefined

The splice() method changes the content of an array by removing existing elements and/or adding new elements.

Syntax: array.splice(start, deleteCount[, item1[, item2[, ...]]])

var people = ["Bob", "Sally", "Jack"]_x000D_
var toRemove = 'Bob';_x000D_
var index = people.indexOf(toRemove);_x000D_
if (index > -1) { //Make sure item is present in the array, without if condition, -n indexes will be considered from the end of the array._x000D_
  people.splice(index, 1);_x000D_
}_x000D_
console.log(people);

Edit:

As pointed out by justin-grant, As a rule of thumb, Never mutate this.state directly, as calling setState() afterward may replace the mutation you made. Treat this.state as if it were immutable.

The alternative is, create copies of the objects in this.state and manipulate the copies, assigning them back using setState(). Array#map, Array#filter etc. could be used.

this.setState({people: this.state.people.filter(item => item !== e.target.value);});

If you are using git for Windows.

• Open the git GUI.
• Open the local git repository in git GUI.
• Add the remote or push if the remote already exists.
• Answer "yes" to the question about whether you want to continue.

The GUI client adds the key for you to ~/.ssh/known_hosts. This is easier to remember if you don't do it often and also avoids the need to use the git command line (the standard Windows command lines don't have the ssh-keyscan executable.

Very probable that your VISUAL environment variable is set to something else. Try:

export VISUAL=vi

I found more accurate way to adding views like linear layouts in kotlin (Pass parent layout in inflate() and false)

val parentLayout = view.findViewById<LinearLayout>(R.id.llRecipientParent)
val childView = layoutInflater.inflate(R.layout.layout_recipient, parentLayout, false)
parentLayout.addView(childView)

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

A Container can take a BoxDecoration (going off of the code you had originally posted) which takes a boxShadow:

decoration: BoxDecoration(
    borderRadius: BorderRadius.circular(10),
    boxShadow: [
        BoxShadow(
            color: Colors.grey.withOpacity(0.5),
            spreadRadius: 5,
            blurRadius: 7,
            offset: Offset(0, 3), // changes position of shadow
        ),
    ],
),

I had the same problem. The cause was that I had the same jquery several times. He was placed in a loop.

$ (". AddProduct"). click (function () {});
$ (". AddProduct"). click (function () {});
$ (". AddProduct"). click (function () {});
$ (". AddProduct"). click (function () {});
$ (". AddProduct"). click (function () {});

For this reason was firing multiple times

#register a:link
{
color:#fffff;
}

In Visual Studio 2017 Spanish version.

"Depurar" -> "Ventanas" -> "Configuración de Excepciones"

and search "ContextSwitchDeadlock". Then, uncheck it. Or shortcut

Ctrl+D,E

Best.

I was successful using tidy command line utility. On linux I installed it quickly with apt-get install tidy. Then the command:

tidy -q -asxml --numeric-entities yes source.html >file.xml

gave an xml file, which I was able to process with xslt processor. However I needed to set up xhtml1 dtds correctly.

Hyphens, underscores, periods, colons, numbers and letters are all valid for use with CSS and JQuery. The following should work but it must be unique throughout the page and also must start with a letter [A-Za-z].

Working with colons and periods needs a bit more work but you can do it as the following example shows.

<html>
<head>
<title>Cake</title>
<style type="text/css">
    #i\.Really\.Like\.Cake {
        color: green;
    }
    #i\:Really\:Like\:Cake {
        color: blue;
    }
</style>
</head>
<body>
    <div id="i.Really.Like.Cake">Cake</div>
    <div id="testResultPeriod"></div>

    <div id="i:Really:Like:Cake">Cake</div>
    <div id="testResultColon"></div>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
    <script type="text/javascript">
        $(function() {
            var testPeriod = $("#i\\.Really\\.Like\\.Cake");
            $("#testResultPeriod").html("found " + testPeriod.length + " result.");

            var testColon = $("#i\\:Really\\:Like\\:Cake");
            $("#testResultColon").html("found " + testColon.length + " result.");
        });
    </script>
</body>
</html>

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.

This means that a TCP RST was received and the connection is now closed. This occurs when a packet is sent from your end of the connection but the other end does not recognize the connection; it will send back a packet with the RST bit set in order to forcibly close the connection.

This can happen if the other side crashes and then comes back up or if it calls close() on the socket while there is data from you in transit, and is an indication to you that some of the data that you previously sent may not have been received.

It is up to you whether that is an error; if the information you were sending was only for the benefit of the remote client then it may not matter that any final data may have been lost. However you should close the socket and free up any other resources associated with the connection.

The only viable solution in my opinion is to use

• an ID INT IDENTITY(1,1) column to get SQL Server to handle the automatic increment of your numeric value
• a computed, persisted column to convert that numeric value to the value you need

So try this:

CREATE TABLE dbo.tblUsers
  (ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
   UserID AS 'UID' + RIGHT('00000000' + CAST(ID AS VARCHAR(8)), 8) PERSISTED,
   .... your other columns here....
  )

Now, every time you insert a row into tblUsers without specifying values for ID or UserID:

INSERT INTO dbo.tblUsersCol1, Col2, ..., ColN)
VALUES (Val1, Val2, ....., ValN)

then SQL Server will automatically and safely increase your ID value, and UserID will contain values like UID00000001, UID00000002,...... and so on - automatically, safely, reliably, no duplicates.

Update: the column UserID is computed - but it still OF COURSE has a data type, as a quick peek into the Object Explorer reveals:

I have made a little example using css

  position: relative;_x000D_
  top: 50px;_x000D_
  left: 50px;_x000D_
}_x000D_
_x000D_
.tooltip {_x000D_
  /* hide and position tooltip */_x000D_
  top: -10px;_x000D_
  background-color: black;_x000D_
  color: white;_x000D_
  border-radius: 5px;_x000D_
  opacity: 0;_x000D_
  position: absolute;_x000D_

_x000D_
.hover:hover .tooltip {_x000D_
  /* display tooltip on hover */_x000D_
  opacity: 1;_x000D_

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

This is being described in this article. Think about forEach of Collections.

List<?> list = …
list.forEach(…);

The forEach isn’t declared by java.util.List nor the java.util.Collection interface yet. One obvious solution would be to just add the new method to the existing interface and provide the implementation where required in the JDK. However, once published, it is impossible to add methods to an interface without breaking the existing implementation.

The benefit that default methods bring is that now it’s possible to add a new default method to the interface and it doesn’t break the implementations.

In jQueryUI 1.8.9 using className rather than classes works.

$('#element').dialog({
  buttons:{
    "send":{
      text:'Send',
      className:'save'
    },
    "cancel":{
      text:'Cancel',
      className:'cancel'
    }
  });

my_var = (int)my_var;

As simple as that. Basically you don't need it if the variable is int.

public static byte[] serialize(Object obj) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(out);
    os.writeObject(obj);
    return out.toByteArray();
}
public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {
    ByteArrayInputStream in = new ByteArrayInputStream(data);
    ObjectInputStream is = new ObjectInputStream(in);
    return is.readObject();
}

You can change action bar color on this way:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/green_action_bar</item>
</style>

Thats all you need for changing action bar color.

Plus if you want to change the status bar color just add the line:

 <item name="android:colorPrimaryDark">@color/green_dark_action_bar</item>

Here is a screenshot taken from developer android site to make it more clear, and here is a link to read more about customizing the color palete

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>
    This page code gets rendered.
</c:if>

When it gets to real world usage of these datatypes, it is very important that you understand that using certain integer types could just be an overkill or under used. For example, using integer datatype for employeeCount in a table say employee could be an overkill since it supports a range of integer values from ~ negative 2 billion to positive 2 billion or zero to approximately 4 billion (unsigned). So, even if you consider one of the US biggest employer such as Walmart with roughly about 2.2 million employees using an integer datatype for the employeeCount column would be unnecessary. In such a case you use mediumint (that supports from 0 to 16 million (unsigned)) for example. Having said that if your range is expected to be unusually large you might consider bigint which as you can see from Daniel's notes supports a range larger than I care to decipher.

For protobuf 2.5, use the dependency:

"com.googlecode.protobuf-java-format" % "protobuf-java-format" % "1.2"

Then use the code:

com.googlecode.protobuf.format.JsonFormat.merge(json, builder)
com.googlecode.protobuf.format.JsonFormat.printToString(proto)

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

The statement a = a + " " + b + " " + c can be broken down based upon pointers.

a + " " says give me what a points to, which can't be changed, and add " " to my current working set.

memory:

working_set = "Dog "
a = "Dog" 
b = "eats"
c = "treats"

+ b says give me what b points to, which can't be changed, and add it to current working set.

memory:

working_set = "Dog eats"
a = "Dog" 
b = "eats"
c = "treats"

+ " " + c says add " " to the current set. Then give me what c points to, which can't be changed, and add it to current working set. memory:

working_set = "Dog eats treats"
a = "Dog" 
b = "eats"
c = "treats"

Finally, a = says set my pointer to point to the resulting set.

memory:

a = "Dog eats treats"
b = "eats"
c = "treats"

"Dog" is reclaimed, because no more pointers connect to it's chunk of memory. We never modified the memory section "Dog" resided in, which is what is meant by immutable. However, we can change which labels, if any, point to that section of memory.

Just putting it out there:

JsonPath jsonPathEvaluator = response.jsonPath();
return jsonPathEvaluator.get("user_id").toString();

This should work for you:

Consider Table1 has a column by the name of activity which may have the same value in more than one record. This is how you will extract ONLY the unique entries of activity field within Table1.

#An array of multiple data entries
@table1 = Table1.find(:all) 

#extracts **activity** for each entry in the array @table1, and returns only the ones which are unique 

@unique_activities = @table1.map{|t| t.activity}.uniq 

Even after this my code is working fine , so i just removed all warning messages with this statement at line 1 .

<?php error_reporting(E_ERROR); ?>

Yes, 1 byte does encode a character (inc spaces etc) from the ASCII set. However in data units assigned to character encoding it can and often requires in practice up to 4 bytes. This is because English is not the only character set. And even in English documents other languages and characters are often represented. The numbers of these are very many and there are very many other encoding sets, which you may have heard of e.g. BIG-5, UTF-8, UTF-32. Most computers now allow for these uses and ensure the least amount of garbled text (which usually means a missing encoding set.) 4 bytes is enough to cover these possible encodings. I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings, not just ASCII. The final character may only need a byte to function or be represented on screen, but requires 4 bytes to be located in the rather vast global encoding "works".

Just use com.google.common.io.Resources class. Example:

 URL url = Resources.getResource("file name")

After that you have methods like: .getContent(), .getFile(), .getPath() etc

Something like this should do it too :

$last = $wpdb->get_row("SHOW TABLE STATUS LIKE 'table_name'");
$lastid = $last->Auto_increment;
