jenkins.exe restart

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

I had faced same problem because I downloaded TestNG plugin from Eclipse. Here what I did to get the Job done :

1. After adding TestNG to your project library create one folder in your Project names as lib ( name can be anything ) :

2. Go to "C:\Program Files\Eclipse\eclipse-java-mars-R-win32-x86_64\eclipse\plugins" location and copy com.beust.jcommander_1.72.0.jar and org.testng_6.14.2.r20180216145.jar file to created folder (lib).

Note : Files are testng.jar and jcommander.jar

3. Now Launch CMD, and navigate to your project directory and then type :
   Java -cp C:\Users\User123\TestNG\lib*;C:\Users\User123\TestNG\bin org.testng.TestNG testng.xml

That's it !
Let me know if you have any more concerns.

Runas doesn't magically run commands as an administrator, it runs them as whatever account you provide credentials for. If it's not an administrator account, runas doesn't care.

Using the Drag and Drop method

1. From the windows search bar type in cmd to pull up the windows bar operation.
2. When the command line option is shown, right click it and select Open File Location.
3. The file explorer opens and the shortcut link is highlighted in the folder. If it is not highlighted, then select it.
4. Hold down the Control key and using the mouse drag the shortcut to the desktop. If you don't see Copy to Desktop while dragging and before dropping, then push down and hold the Control key until you see the message.
5. Drop the link on the desktop.
6. Change properties as needed.

FileZilla Works well. I Use FileZilla FTP Client "Manual Transfer" which supports Passive mode.

Example: Open FileZilla and Select "Transfer" >> "Manual Transfer" then within the Manual Transfer Window, perform the following:

1. Confirm proper Download / Upload option is selected
2. For Remote: Enter name of directory where the file to download is located
3. For Remote: Enter the name of the file to be downloaded
4. For Local: Browse to desired directory you want to download file to
5. For Local: Enter a file name to save downloaded file As (use same file name as file to be downloaded unless you want to change it)
6. Check-Box "Start transfer immediately" and Click "OK"
7. Download should start momentarily
8. Note: If you forgot to Check-Box "Start transfer immediately"... No Problem: just Right-Click on the file to be downloaded (within the Process Queue (file transfer queue) at the bottom of the FileZilla window pane and Select "Process Queue"
9. Download process should begin momentarily
10. Done

you can create batch file and insert into it the bellow line:

cmd /k start chrome "http://yourWebSite.com

after that you do just double click on this batch file.

Ok so I just found a really decent work around to this issue. CMDKEY works on windows 7+ and allows you to enter details into the windows cred manager from the cmd prompt, and if you use the /pass switch it provides its own password entry without exposing the password. It does not present ***** as you type but the password is hidden.

The script below requests the username as normal and creates a var called "%username%" it then checks to see if the cred manager already has an entry for the target server. If it does it just maps the drive to the usename and does not request a password. If there is no entry it then uses the CMDKEY to prompt for password and stores it in cred manager.

    set /p username="Enter School Username: "
    CMDKEY /list:SERVERNAME | FIND "NONE" > nul 2>&1
    IF %ERRORLEVEL% NEQ 0 GOTO MAPDRIVES
    CMDKEY /ADD:SERVERNAME /username:%username% /pass
    :MAPDRIVES
    NET USE Y: \\SERVERNAME\SHARE\%username%

An update to @rleelr:
It's possible to view proxy settings in Google Chrome:

chrome://net-internals/#http2

Then select

View live HTTP/2 sessions

Then select one of the live sessions (you need to have some tabs open). There you find:

[...]
t=504112 [st= 0] +HTTP2_SESSION  [dt=?]
                  --> host = "play.google.com:443"
                  --> proxy = "PROXY www.xxx.yyy.zzz:8080"
[...]
                              ============================

TL;DR

For experienced readers:

1. Find the Java path; it looks like this: C:\Program Files\Java\jdkxxxx\bin\
2. Start-menu search for "environment variable" to open the options dialog.
3. Examine PATH. Remove old Java paths.
4. Add the new Java path to PATH.
5. Edit JAVA_HOME.
6. Close and re-open console/IDE.

Welcome!

You have encountered one of the most notorious technical issues facing Java beginners: the 'xyz' is not recognized as an internal or external command... error message.

In a nutshell, you have not installed Java correctly. Finalizing the installation of Java on Windows requires some manual steps. You must always perform these steps after installing Java, including after upgrading the JDK.

Environment variables and PATH

(If you already understand this, feel free to skip the next three sections.)

When you run javac HelloWorld.java, cmd must determine where javac.exe is located. This is accomplished with PATH, an environment variable.

An environment variable is a special key-value pair (e.g. windir=C:\WINDOWS). Most came with the operating system, and some are required for proper system functioning. A list of them is passed to every program (including cmd) when it starts. On Windows, there are two types: user environment variables and system environment variables.

You can see your environment variables like this:

C:\>set
ALLUSERSPROFILE=C:\ProgramData
APPDATA=C:\Users\craig\AppData\Roaming
CommonProgramFiles=C:\Program Files\Common Files
CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files
CommonProgramW6432=C:\Program Files\Common Files
...

The most important variable is PATH. It is a list of paths, separated by ;. When a command is entered into cmd, each directory in the list will be scanned for a matching executable.

On my computer, PATH is:

C:\>echo %PATH%
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPower
Shell\v1.0\;C:\ProgramData\Microsoft\Windows\Start Menu\Programs;C:\Users\craig\AppData\
Roaming\Microsoft\Windows\Start Menu\Programs;C:\msys64\usr\bin;C:\msys64\mingw64\bin;C:\
msys64\mingw32\bin;C:\Program Files\nodejs\;C:\Program Files (x86)\Yarn\bin\;C:\Users\
craig\AppData\Local\Yarn\bin;C:\Program Files\Java\jdk-10.0.2\bin;C:\ProgramFiles\Git\cmd;
C:\Program Files\Oracle\VirtualBox;C:\Program Files\7-Zip\;C:\Program Files\PuTTY\;C:\
Program Files\launch4j;C:\Program Files (x86)\NSIS\Bin;C:\Program Files (x86)\Common Files
\Adobe\AGL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program
Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\iCLS Client\;
C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files
(x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\iCLS
Client\;C:\Users\craig\AppData\Local\Microsoft\WindowsApps

When you run javac HelloWorld.java, cmd, upon realizing that javac is not an internal command, searches the system PATH followed by the user PATH. It mechanically enters every directory in the list, and checks if javac.com, javac.exe, javac.bat, etc. is present. When it finds javac, it runs it. When it does not, it prints 'javac' is not recognized as an internal or external command, operable program or batch file.

You must add the Java executables directory to PATH.

JDK vs. JRE

(If you already understand this, feel free to skip this section.)

When downloading Java, you are offered a choice between:

• The Java Runtime Environment (JRE), which includes the necessary tools to run Java programs, but not to compile new ones – it contains java but not javac.
• The Java Development Kit (JDK), which contains both java and javac, along with a host of other development tools. The JDK is a superset of the JRE.

You must make sure you have installed the JDK. If you have only installed the JRE, you cannot execute javac because you do not have an installation of the Java compiler on your hard drive. Check your Windows programs list, and make sure the Java package's name includes the words "Development Kit" in it.

Don't use set

(If you weren't planning to anyway, feel free to skip this section.)

Several other answers recommend executing some variation of:

C:\>:: DON'T DO THIS
C:\>set PATH=C:\Program Files\Java\jdk1.7.0_09\bin

Do not do that. There are several major problems with that command:

1. This command erases everything else from PATH and replaces it with the Java path. After executing this command, you might find various other commands not working.
2. Your Java path is probably not C:\Program Files\Java\jdk1.7.0_09\bin – you almost definitely have a newer version of the JDK, which would have a different path.
3. The new PATH only applies to the current cmd session. You will have to reenter the set command every time you open Command Prompt.

Points #1 and #2 can be solved with this slightly better version:

C:\>:: DON'T DO THIS EITHER
C:\>set PATH=C:\Program Files\Java\<enter the correct Java folder here>\bin;%PATH%

But it is just a bad idea in general.

Find the Java path

The right way begins with finding where you have installed Java. This depends on how you have installed Java.

Exe installer

You have installed Java by running a setup program. Oracle's installer places versions of Java under C:\Program Files\Java\ (or C:\Program Files (x86)\Java\). With File Explorer or Command Prompt, navigate to that directory.

Each subfolder represents a version of Java. If there is only one, you have found it. Otherwise, choose the one that looks like the newer version. Make sure the folder name begins with jdk (as opposed to jre). Enter the directory.

Then enter the bin directory of that.

You are now in the correct directory. Copy the path. If in File Explorer, click the address bar. If in Command Prompt, copy the prompt.

The resulting Java path should be in the form of (without quotes):

C:\Program Files\Java\jdkxxxx\bin\

Zip file

You have downloaded a .zip containing the JDK. Extract it to some random place where it won't get in your way; C:\Java\ is an acceptable choice.

Then locate the bin folder somewhere within it.

You are now in the correct directory. Copy its path. This is the Java path.

Remember to never move the folder, as that would invalidate the path.

Open the settings dialog

That is the dialog to edit PATH. There are numerous ways to get to that dialog, depending on your Windows version, UI settings, and how messed up your system configuration is.

Try some of these:

• Start Menu/taskbar search box » search for "environment variable"
• Win + R » control sysdm.cpl,,3
• Win + R » SystemPropertiesAdvanced.exe » Environment Variables
• File Explorer » type into address bar Control Panel\System and Security\System » Advanced System Settings (far left, in sidebar) » Environment Variables
• Desktop » right-click This PC » Properties » Advanced System Settings » Environment Variables
• Start Menu » right-click Computer » Properties » Advanced System Settings » Environment Variables
• Control Panel (icon mode) » System » Advanced System Settings » Environment Variables
• Control Panel (category mode) » System and Security » System » Advanced System Settings » Environment Variables
• Desktop » right-click My Computer » Advanced » Environment Variables
• Control Panel » System » Advanced » Environment Variables

Any of these should take you to the right settings dialog.

If you are on Windows 10, Microsoft has blessed you with a fancy new UI to edit PATH. Otherwise, you will see PATH in its full semicolon-encrusted glory, squeezed into a single-line textbox. Do your best to make the necessary edits without breaking your system.

Clean PATH

Look at PATH. You almost definitely have two PATH variables (because of user vs. system environment variables). You need to look at both of them.

Check for other Java paths and remove them. Their existence can cause all sorts of conflicts. (For instance, if you have JRE 8 and JDK 11 in PATH, in that order, then javac will invoke the Java 11 compiler, which will create version 55 .class files, but java will invoke the Java 8 JVM, which only supports up to version 52, and you will experience unsupported version errors and not be able to compile and run any programs.) Sidestep these problems by making sure you only have one Java path in PATH. And while you're at it, you may as well uninstall old Java versions, too. And remember that you don't need to have both a JDK and a JRE.

If you have C:\ProgramData\Oracle\Java\javapath, remove that as well. Oracle intended to solve the problem of Java paths breaking after upgrades by creating a symbolic link that would always point to the latest Java installation. Unfortunately, it often ends up pointing to the wrong location or simply not working. It is better to remove this entry and manually manage the Java path.

Now is also a good opportunity to perform general housekeeping on PATH. If you have paths relating to software no longer installed on your PC, you can remove them. You can also shuffle the order of paths around (if you care about things like that).

Add to PATH

Now take the Java path you found three steps ago, and place it in the system PATH.

It shouldn't matter where in the list your new path goes; placing it at the end is a fine choice.

If you are using the pre-Windows 10 UI, make sure you have placed the semicolons correctly. There should be exactly one separating every path in the list.

There really isn't much else to say here. Simply add the path to PATH and click OK.

Set JAVA_HOME

While you're at it, you may as well set JAVA_HOME as well. This is another environment variable that should also contain the Java path. Many Java and non-Java programs, including the popular Java build systems Maven and Gradle, will throw errors if it is not correctly set.

If JAVA_HOME does not exist, create it as a new system environment variable. Set it to the path of the Java directory without the bin/ directory, i.e. C:\Program Files\Java\jdkxxxx\.

Remember to edit JAVA_HOME after upgrading Java, too.

Close and re-open Command Prompt

Though you have modified PATH, all running programs, including cmd, only see the old PATH. This is because the list of all environment variables is only copied into a program when it begins executing; thereafter, it only consults the cached copy.

There is no good way to refresh cmd's environment variables, so simply close Command Prompt and open it again. If you are using an IDE, close and re-open it too.

• What are PATH and other environment variables, and how can I set or use them?
• How do I set or change the PATH system variable?
• How to set the path and environment variables in Windows
• How to set Path environment variables in Windows 10

Easiest way to do this

1. Click "Start" and type "cmd" or "command prompt".
2. Select Top most search application named exactly same "cmd" or "command prompt".
3. Right Click on it and select "Send To"=>"Desktop".
4. On Your Desktop New "cmd" Shortcut will appear
5. Right Click on that icon and choose "properties"
6. Popup will appear, In "Shortcut" Tab Type the new location in "Start In" option (e.g D:\xyz)
7. Drag that icon and add/pin it in "Task Bar"

This can work too:

chmod -R 755 *  // All files and folders to 755.

chmod -R 644 *.*  // All files will be 644.

If you want to setup for temporary purpose, just execute below command.

1. open command prompt < run --> cmd >
2. Run below command.
   set PATH=C:\Program Files\Git\bin;%PATH%
3. Type git, it will work.

This is valid for current window/cell only, if you will close command prompt, everything will get vanish. For permanently setting, set GIT in environment variable.

a. press Window+Pause
b. click on Advance system setting.

c. Click on Environment variable under Advance Tab.

d. Edit Path Variable.

e. Add below line in end of statement.
;c:\Program Files\Git\bin;

f. Press OK!!
g. Open new command prompt .
h. Type git and press Enter

Thanks

There is an important detail:

set PATH="C:\linutils;C:\wingit\bin;%PATH%"

does not work, while

set PATH=C:\linutils;C:\wingit\bin;%PATH%

works. The difference is the quotes!

UPD also see the comment by venimus

You can minimize the command prompt on during the run but you'll need two additional scripts: windowMode and getCmdPid.bat:

@echo off

call getCmdPid
call windowMode -pid %errorlevel% -mode minimized

cd /d C:\leads\ssh 
call C:\Ruby192\bin\setrbvars.bat
ruby C:\leads\ssh\put_leads.rb

It looks like psexec -h is the way to do this:

 -h         If the target system is Windows Vista or higher, has the process
            run with the account's elevated token, if available.

Which... doesn't seem to be listed in the online documentation in Sysinternals - PsExec.

But it works on my machine.

1. Run Windows Command Prompt as Administrator
2. paste this code: cd C:\Windows\Microsoft.NET\Framework\v4.0.30319\ to go to folder
3. edit and run this too: installutil C:\ProjectFolder\bin\Debug\MyProject.exe

Note: To uninstall: installutil /u C:\ProjectFolder\bin\Debug\MyProject.exe

type sqlplus/"as sysdba" in cmd for connection in cmd prompt

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

It will give you all active sockets on a specific IP:

netstat -an | find "172.20.1.166"

Remove the file: C:/Sites/folder/Pids/Server.pids

Explanation In UNIX land at least we usually track the process id (pid) in a file like server.pid. I think this is doing the same thing here. That file was probably left over from a crash.

for /d %i in ("\Program Files\Java\jdk*") do set JAVA_HOME=%i
set JAVA_HOME

this solution worked to me

excellent point Calin Darie

I had a lot of scripts to use cacls I move them to icacls how ever I could not find a script to change the root mount volumes example: d:\datafolder. I finally crated the script below, which mounts the volume as a temporary drive then applies sec. then unmounts it. It is the only way I found that you can update the root mount security.

1 gets the folder mount GUID to a temp file then reads the GUID to mount the volume as a temp drive X: applies sec and logs the changes then unmounts the Volume only from the X: drive so the mounted folder is not altered or interrupted other then the applied sec.

here is sample of my script:

**mountvol "d:\%1" /L >tempDrive.temp && FOR /f "tokens=*" %%I IN (tempDrive.temp) DO mountvol X: %%I 
D:\tools\security\icacls.exe  %~2 /grant domain\group:(OI)(CI)F /T /C >>%~1LUNsec-%TDWEEK%-%TMONTH%-%TDAY%-%TYEAR%-%THOUR%-%TMINUTE%-%TAM%.txt
if exist x:\*.* mountvol X: /d**

If you already know the port number, it will probably suffice to send a software termination signal to the process (SIGTERM):

kill $(lsof -t -i :PORT_NUMBER)

cd has a parameter /d, which will change drive and path with one command:

cd /d d:\temp

( see cd /?)

The answer in "peculiarity" is correct and directly answers the question. As TimF answered, since the first parameter is in quotes, it is treated as a window title.

Also note that the Virtual PC options are being treated as options to the 'start' command itself, and are not valid for 'start'. This is true for all versions of Windows that have the 'start' command.

This problem with 'start' treating the quoted parameter as a title is even more annoying that just the posted problem. If you run this:

start "some valid command with spaces"

You get a new command prompt window, with the obvious result for a window title. Even more annoying, this new window doesn't inherit customized font, colors or window size, it's just the default for cmd.exe.

If splitting very large files, the solution I found is an adaptation from this, with PowerShell "embedded" in a batch file. This works fast, as opposed to many other things I tried (I wouldn't know about other options posted here).

The way to use mysplit.bat below is

mysplit.bat <mysize> 'myfile'

Note: The script was intended to use the first argument as the split size. It is currently hardcoded at 100Mb. It should not be difficult to fix this.

Note 2: The filname should be enclosed in single quotes. Other alternatives for quoting apparently do not work.

Note 3: It splits the file at given number of bytes, not at given number of lines. For me this was good enough. Some lines of code could be probably added to complete each chunk read, up to the next CR/LF. This will split in full lines (not with a constant number of them), with no sacrifice in processing time.

In the Windows command prompt you can disable tab completion, by launching it thusly:

cmd.exe /f:off

Then the tab character will be echoed to the screen and work as you expect. Or you can disable the tab completion character, or modify what character is used for tab completion by modifying the registry.

The cmd.exe help page explains it:

You can enable or disable file name completion for a particular invocation of CMD.EXE with the /F:ON or /F:OFF switch. You can enable or disable completion for all invocations of CMD.EXE on a machine and/or user logon session by setting either or both of the following REG_DWORD values in the registry using REGEDIT.EXE:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar

    and/or

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar

with the hex value of a control character to use for a particular function (e.g. 0x4 is Ctrl-D and 0x6 is Ctrl-F). The user specific settings take precedence over the machine settings. The command line switches take precedence over the registry settings.

If completion is enabled with the /F:ON switch, the two control characters used are Ctrl-D for directory name completion and Ctrl-F for file name completion. To disable a particular completion character in the registry, use the value for space (0x20) as it is not a valid control character.

For duplicating large files, xopy with /J switch is a good choice. In this case, simply pipe an F for file or a D for directory. Also, you can save jobs in an array for future references. For example:

$MyScriptBlock = {
    Param ($SOURCE, $DESTINATION) 
    'F' | XCOPY $SOURCE $DESTINATION /J/Y 
    #DESTINATION IS FILE, COPY WITHOUT PROMPT IN DIRECT BUFFER MODE
}
JOBS +=START-JOB -SCRIPTBLOCK $MyScriptBlock -ARGUMENTLIST $SOURCE,$DESTIBNATION
$JOBS | WAIT-JOB | REMOVE-JOB

you can use help on command prompt on cd command by writing this command cd /? as shown in this figure

typeperf "\processor(_total)\% processor time"

does work on Win7, you just need to extract the percent value yourself from the last quoted string.

For the benefit of searchers, there is another way you can produce this error message - by missing the $ off the script block name when calling it.

e.g. I had a script block like so:

$qa = {
    param($question, $answer)
    Write-Host "Question = $question, Answer = $answer"
}

I tried calling it using:

&qa -question "Do you like powershell?" -answer "Yes!"

But that errored. The correct way was:

&$qa -question "Do you like powershell?" -answer "Yes!"

You can use %systemdrive%%homepath% environment variable to accomplish this.

The two command variables when concatenated gives you the desired user's home directory path as below:

1. Running echo %systemdrive% on command prompt gives:

   C:
   

2. Running echo %homepath% on command prompt gives:

   \Users\<CurrentUserName>
   

When used together it becomes:

C:\Users\<CurrentUserName>

Specify /D to change the drive also.

CD /D %root%

Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:

If Not Exist "C:\Documents and Settings\John\Start Menu\Programs\SoftWareFolder\"

On OSX edit file:

/usr/local/Cellar/jenkins-lts/2.46.1/homebrew.mxcl.jenkins-lts.plist

and edit port to you needs.

"net send" is a command using a background service called "messenger". This service has been removed from Windows 7. ie You cannot use 'net send' on Vista nor Win7 / Win8.

Pity though , I loved using it.

There is alternatives, but that requires you to download and install software on each pc you want to use, this software runs as background services, and i would advise one to be very very very very careful of using these kind of software as they can potentially cause seriously damage one's system or impair the systems securities.

robocopy seems to be the most versatile. See it's other options in the help

Enabling delayed variable expansion solves you problem, the script produces "hi":

setlocal EnableDelayedExpansion

set var1=A
set var2=B

set AB=hi

set newvar=!%var1%%var2%!

You are logging in incorrectly; you should not include = in your login. So to log in, type:

mysql.exe -uroot -padmin

If that doesn't work, then you may not have your system configured. If so, then here's a good tutorial on getting started with the MySQL prompt: http://breakdesign.blogspot.com/2007/11/getting-started-with-php-and-mysql-in_11.html

Not sure if you are coding these programs, but this is a simple example of how you'd do it.

Compile both then run program1.exe "this subject has a submarine as a subsequence" | rgx.exe "\b(sub)([^ ]*)"

The | operator simply redirects the output of program1's printf operation from the stdout stream to the stdin stream whereby it's sitting there waiting for rgx.exe to pick up.

javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command

java -cp classpath-entries mainjava arg1 arg2 should run your code with 2 arguments

A simple

echo "Y Y N N Y N Y Y N" | ./your_script

This allow you to pass any sequence of "Y" or "N" to your script.

None of the answers are working for me on Windows 10, so here's what I use:

@echo off

set DNS1=8.8.8.8
set DNS2=8.8.4.4
set INTERFACE=Ethernet

netsh int ipv4 set dns name="%INTERFACE%" static %DNS1% primary validate=no
netsh int ipv4 add dns name="%INTERFACE%" %DNS2% index=2

ipconfig /flushdns

pause

This uses Google DNS. You can get interface name with the command netsh int show interface

I tried this commands in my PC.It is working fine....

To open notepad in minimized mode:

start /min "" "C:\Windows\notepad.exe"

To open MS word in minimized mode:

start /min "" "C:\Program Files\Microsoft Office\Office14\WINWORD.EXE"

After trying almost every key on my keyboard:

C:\Users\Tim>cd ^
Mehr? Desktop

C:\Users\Tim\Desktop>

So it seems to be the ^ key.

Things like these are why I switched to Powershell. Try it out, it's fun:

Get-ChildItem -Recurse -Include *.doc | % {
    Copy-Item $_.FullName -destination x:\destination
}

you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.

Expanding on roryhewitt answer.

An advantage to using .cmd files over DOSKEY is that these "aliases" are then available in other shells such as PowerShell or WSL (Windows subsystem for Linux).

The only gotcha with using these commands in bash is that it may take a bit more setup since you might need to do some path manipulation before calling your "alias".

eg I have vs.cmd which is my "alias" for editing a file in Visual Studio

@echo off
if [%1]==[] goto nofiles
start "" "c:\Program Files (x86)\Microsoft Visual Studio 
11.0\Common7\IDE\devenv.exe" /edit %1
goto end
:nofiles
start "" "C:\Program Files (x86)\Microsoft Visual Studio 
11.0\Common7\IDE\devenv.exe" "[PATH TO MY NORMAL SLN]"
:end

Which fires up VS (in this case VS2012 - but adjust to taste) using my "normal" project with no file given but when given a file will attempt to attach to a running VS opening that file "within that project" rather than starting a new instance of VS.

For using this from bash I then add an extra level of indirection since "vs Myfile" wouldn't always work

alias vs='/usr/bin/run_visual_studio.sh'

Which adjusts the paths before calling the vs.cmd

#!/bin/bash
cmd.exe /C 'c:\Windows\System32\vs.cmd' "`wslpath.sh -w -r $1`"

So this way I can just do

vs SomeFile.txt

In either a command prompt, Power Shell or bash and it opens in my running Visual Studio for editing (which just saves my poor brain from having to deal with VI commands or some such when I've just been editing in VS for hours).

You can use this jQuery function

function makePostRequest(url, data) {
    var jForm = $('<form></form>');
    jForm.attr('action', url);
    jForm.attr('method', 'post');
    for (name in data) {
        var jInput = $("<input>");
        jInput.attr('name', name);
        jInput.attr('value', data[name]);
        jForm.append(jInput);
    }
    jForm.submit();
}

Here is an example in jsFiddle (http://jsfiddle.net/S7zUm/)

Borrowing from this answer, it seems like the cleanest solution is to use io.TextIOWrapper. I managed to solve this problem for myself as follows:

from io import TextIOWrapper

...

with open(filename, 'wb') as csvfile, TextIOWrapper(csvfile, encoding='utf-8', newline='') as wrapper:
    csvwriter = csv.writer(wrapper)
    for data_row in data:
        csvwriter.writerow(data_row)

The above answer is not compatible with Python 2. To have compatibility, I suppose one would simply need to wrap all the writing logic in an if block:

if sys.version_info < (3,):
    # Python 2 way of handling CSVs
else:
    # The above logic

function getRemote() {
    return $.ajax({
        type: "GET",
        url: remote_url,
        async: false,
        success: function (result) {
            /* if result is a JSon object */
            if (result.valid)
                return true;
            else
                return false;
        }
    });
}

Here's my solution in: http://jsfiddle.net/marvo/3k3CC/2/

Solution posted by Denys S. in the question post:

I quite messed it up with c to c++ conversion (basically env variable stuff), but I got it working with the following code for C++:

#include <string.h>
#include <stdio.h>
#include <jni.h>

jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){

    jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
    jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
    jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
    jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);

    const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
    printf("%s\n", str);

    return (*env)->NewStringUTF(env, str);
}

And next code for java methods:

    public class MainActivity extends Activity {
    private static String LIB_NAME = "thelib";

    static {
        System.loadLibrary(LIB_NAME);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = (TextView) findViewById(R.id.textview);
        tv.setText(this.getJniString());
    }

    // please, let me live even though I used this dark programming technique
    public String messageMe(String text) {
        System.out.println(text);
        return text;
    }

    public native String getJniString();
}

ECMAScript 6 introduced the let statement. You can use it in a for statement.

var ids:string = [];

for(let result of this.results){
   ids.push(result.Id);
}

An other way to get only the filename without querystring is by using parse_url and basename functions :

$parts = parse_url("http://example.com/foo/bar/baz/file.php?a=b&c=d");
$filename = basename($parts["path"]); // this will return 'file.php'

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

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

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

One way to get this error is to forget to use the 'new' keyword when instantiating your Date in javascript like this:

> d = Date();
'Tue Mar 15 2016 20:05:53 GMT-0400 (EDT)'
> typeof(d);
'string'
> d.getFullYear();
TypeError: undefined is not a function

Had you used the 'new' keyword, it would have looked like this:

> el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:08:58 GMT-0400 (EDT)
> typeof(d);
'object'
> d.getFullYear(0);
2016

Another way to get that error is to accidentally re-instantiate a variable in javascript between when you set it and when you use it, like this:

el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:12:13 GMT-0400 (EDT)
> d.getFullYear();
2016
> d = 57 + 23;
80
> d.getFullYear();
TypeError: undefined is not a function

i find that this works for me

db.getCollection('collectionName').findOne({"fieldName" : {$ne: null}})

You can use following addon to handle all subquery related function from laravel 5.5+

https://github.com/maksimru/eloquent-subquery-magic

User::selectRaw('user_id,comments_by_user.total_count')->leftJoinSubquery(
  //subquery
  Comment::selectRaw('user_id,count(*) total_count')
      ->groupBy('user_id'),
  //alias
  'comments_by_user', 
  //closure for "on" statement
  function ($join) {
      $join->on('users.id', '=', 'comments_by_user.user_id');
  }
)->get();

The empty space char would be ' '. If you're looking for null that would be '\0'.

You can actually change the grey box around the dropdown arrow in IE:

        select::-ms-expand {
            width:12px;
            border:none;
            background:#fff;
        }

You should use double slash:

var regex = new RegExp("\\?", "g");

Why? because in JavaScript the \ is also used to escape characters in strings, so: "\?" becomes: "?"

And "\\?", becomes "\?"

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

As explained in the section 9 of the official ECMA specification (http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) in JSON, the following chars have to be escaped:

• U+0022 (", the quotation mark)
• U+005C (\, the backslash or reverse solidus)
• U+0000 to U+001F (the ASCII control characters)

In addition, in order to safely embed JSON in HTML, the following chars have to be also escaped:

• U+002F (/)
• U+0027 (')
• U+003C (<)
• U+003E (>)
• U+0026 (&)
• U+0085 (Next Line)
• U+2028 (Line Separator)
• U+2029 (Paragraph Separator)

Some of the above characters can be escaped with the following short escape sequences defined in the standard:

• \" represents the quotation mark character (U+0022).
• \\ represents the reverse solidus character (U+005C).
• \/ represents the solidus character (U+002F).
• \b represents the backspace character (U+0008).
• \f represents the form feed character (U+000C).
• \n represents the line feed character (U+000A).
• \r represents the carriage return character (U+000D).
• \t represents the character tabulation character (U+0009).

The other characters which need to be escaped will use the \uXXXX notation, that is \u followed by the four hexadecimal digits that encode the code point.

The \uXXXX can be also used instead of the short escape sequence, or to optionally escape any other character from the Basic Multilingual Plane (BMP).

This happens because the JSON format uses ""(Quotes) and anything in between these quotes is useful information (either key or the data).

Suppose your data was : He said "This is how it is done". Then the actual data should look like "He said \"This is how it is done\".".

This ensures that the \" is treated as "(Quotation mark) and not as JSON formatting. This is called escape character.

This usually happens when one tries to encode an already JSON encoded data, which is a common way I have seen this happen.

Try this

$arr = ['This is a sample','This is also a "sample"']; echo json_encode($arr);

OUTPUT:

["This is a sample","This is also a \"sample\""]

' add item to array
Function AddItem(arr, val)
    ReDim Preserve arr(UBound(arr) + 1)
    arr(UBound(arr)) = val
    AddItem = arr
End Function

Used like so

a = Array()
a = AddItem(a, 5)
a = AddItem(a, "foo")

String s = "xyz";
for(int i = 0; i < s.length(); i++)
{
   char c = s.charAt(i);
}

Also:

func getTime() -> (hour: Int, minute: Int,second: Int) {
    let hour = 1
    let minute = 2
    let second = 3
    return ( hour, minute, second)
}

Then it's invoked as:

let time = getTime()
print("hour: \(time.hour), minute: \(time.minute), second: \(time.second)")

This is the standard way how to use it in the book The Swift Programming Language written by Apple.

or just like:

let time = getTime()
print("hour: \(time.0), minute: \(time.1), second: \(time.2)")

it's the same but less clearly.

Very easily we can parse JSON content with the help of dictionary and JavaScriptSerializer. Here is the sample code by which I parse JSON content from an ashx file.

var jss = new JavaScriptSerializer();
string json = new StreamReader(context.Request.InputStream).ReadToEnd();
Dictionary<string, string> sData = jss.Deserialize<Dictionary<string, string>>(json);
string _Name = sData["Name"].ToString();
string _Subject = sData["Subject"].ToString();
string _Email = sData["Email"].ToString();
string _Details = sData["Details"].ToString();

Assuming your process is a single thread, and that you're using blocking I/O, your process will block waiting for the I/O to complete. The kernel will pick another process to run in the meantime based on niceness, priority, last run time, etc. If there are no other runnable processes, the kernel won't run any; instead, it'll tell the hardware the machine is idle (which will result in lower power consumption).

Processes that are waiting for I/O to complete typically show up in state D in, e.g., ps and top.

Just to elaborate on the etymology of the command name rev-parse, Git consistently uses the term rev in plumbing commands as short for "revision" and generally meaning the 40-character SHA1 hash for a commit. The command rev-list for example prints a list of 40-char commit hashes for a branch or whatever.

In this case the name might be expanded to parse-a-commitish-to-a-full-SHA1-hash. While the command has the several ancillary functions mentioned in Tuxdude's answer, its namesake appears to be the use case of transforming a user-friendly reference like a branch name or abbreviated hash into the unambiguous 40-character SHA1 hash most useful for many programming/plumbing purposes.

I know I was thinking it was "reverse-parse" something for quite a while before I figured it out and had the same trouble making sense of the terms "massaging" and "manipulation" :)

Anyway, I find this "parse-to-a-revision" notion a satisfying way to think of it, and a reliable concept for bringing this command to mind when I need that sort of thing. Frequently in scripting Git you take a user-friendly commit reference as user input and generally want to get it resolved to a validated and unambiguous working reference as soon after receiving it as possible. Otherwise input translation and validation tends to proliferate through the script.

Let obj be your object. Exec:

(_ => _[Object.keys(_).pop()])( obj )

You can use the localeCompare() method.

string_a.localeCompare(string_b);

/* Expected Returns:

 0:  exact match

-1:  string_a < string_b

 1:  string_a > string_b

 */

You can also use Json.NET. Just download it at http://james.newtonking.com/pages/json-net.aspx, extract the compressed file and add it as a reference.

Then just serialize the list (or whatever object you want) with the following:

using Newtonsoft.Json;

string json = JsonConvert.SerializeObject(listTop10);

Update: you can also add it to your project via the NuGet Package Manager (Tools --> NuGet Package Manager --> Package Manager Console):

PM> Install-Package Newtonsoft.Json

puts adds a new line to the end of each argument if there is not one already.

print does not add a new line.

For example:

puts [[1,2,3], [4,5,nil]] Would return:

1
2
3
4
5

Whereas print [[1,2,3], [4,5,nil]] would return:

[[1,2,3], [4,5,nil]]

Notice how puts does not output the nil value whereas print does.

Not as clean as bool(c) but it was an excuse to use ternary.

def myfunc(a,b):
    return True if a.intersection(b) else False

Also using a bit of the same logic there is no need to assign to c unless you are using it for something else.

def myfunc(a,b):
    return bool(a.intersection(b))

Finally, I would assume you want a True / False value because you are going to perform some sort of boolean test with it. I would recommend skipping the overhead of a function call and definition by simply testing where you need it.

Instead of:

if (myfunc(a,b)):
    # Do something

Maybe this:

if a.intersection(b):
    # Do something

I think the simplest way to just open a single database and start querying is:

sqlite> .open "test.db"
sqlite> SELECT * FROM table_name ... ;

Notice: This works only for versions 3.8.2+

As others said wc -l is the best solution, but for future reference you can use Perl:

perl -lne 'END { print $. }'

$. contains line number and END block will execute at the end of script.

Take a look at Multithreading Tutorial by John Kopplin.

In the section Synchronization Between Threads, he explain the differences among event, lock, mutex, semaphore, waitable timer

A mutex can be owned by only one thread at a time, enabling threads to coordinate mutually exclusive access to a shared resource

Critical section objects provide synchronization similar to that provided by mutex objects, except that critical section objects can be used only by the threads of a single process

Another difference between a mutex and a critical section is that if the critical section object is currently owned by another thread, EnterCriticalSection() waits indefinitely for ownership whereas WaitForSingleObject(), which is used with a mutex, allows you to specify a timeout

A semaphore maintains a count between zero and some maximum value, limiting the number of threads that are simultaneously accessing a shared resource.

Nobody mentioned this, but in some cases the other method fails to recognize the datetime...

You can try this instead, which will convert the specified string representation of a date and time to an equivalent date and time value

string iDate = "05/05/2005";
DateTime oDate = Convert.ToDateTime(iDate);
MessageBox.Show(oDate.Day + " " + oDate.Month + "  " + oDate.Year );

If you want to add REM at the beginning of each line instead of using GOTO, you can use Notepad++ to do this easily following these steps:

1. Select the block of lines
2. hit Ctrl-Q

Repeat steps to uncomment

When I get this kind of error I had to update the data type by a notch. For Example, if I have it as "tiny int" change it to "small int" ~ Nita

You have to sink "output" and "message" separately (the sink function only looks at the first element of type)

Now if you want the input to be logged too, then put it in a script:

script.R

1:5 + 1:3   # prints and gives a warning
stop("foo") # an error

And at the prompt:

con <- file("test.log")
sink(con, append=TRUE)
sink(con, append=TRUE, type="message")

# This will echo all input and not truncate 150+ character lines...
source("script.R", echo=TRUE, max.deparse.length=10000)

# Restore output to console
sink() 
sink(type="message")

# And look at the log...
cat(readLines("test.log"), sep="\n")

Candidate key is a super key from which you cannot remove any fields.

For instance, a software release can be identified either by major/minor version, or by the build date (we assume nightly builds).

Storing date in three fields is not a good idea of course, but let's pretend it is for demonstration purposes:

year  month date  major  minor
2008  01    13     0      1
2008  04    23     0      2
2009  11    05     1      0
2010  04    05     1      1

So (year, major, minor) or (year, month, date, major) are super keys (since they are unique) but not candidate keys, since you can remove year or major and the remaining set of columns will still be a super key.

(year, month, date) and (major, minor) are candidate keys, since you cannot remove any of the fields from them without breaking uniqueness.

You can actually put anything inside a toolbar. See the below code.

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:background="@color/colorPrimary">

</android.support.v7.widget.Toolbar>

Between the above toolbar tag you can put almost anything. That is the benefit of using a Toolbar.

There is no function exit equivalent to php die() in JS, if you are not using any function then you can simply use return;

return;

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

FROM openjdk:8-jdk-alpine RUN apk update && apk add wget openssl lsof procps curl RUN apk update RUN mkdir -p /apps/agent RUN mkdir -p /apps/lib ADD ./app/agent /apps/agent ADD ./app/lib /apps/lib ADD ./app/* /apps/app/ RUN ls -lrt /apps/app/ CMD sh /apps/app/launch.sh

by using DockerFile, I'm copying agent and lib directories to /apps/agent,/apps/lib directories and bunch of files to target.

How to get the First and Last Record of DB in c#.

SELECT TOP 1 * 
  FROM ViewAttendenceReport 
 WHERE EmployeeId = 4 
   AND AttendenceDate >='1/18/2020 00:00:00' 
   AND AttendenceDate <='1/18/2020 23:59:59'
 ORDER BY Intime ASC
 UNION
SELECT TOP 1 * 
  FROM ViewAttendenceReport 
 WHERE EmployeeId = 4 
   AND AttendenceDate >='1/18/2020 00:00:00' 
   AND AttendenceDate <='1/18/2020 23:59:59' 
 ORDER BY OutTime DESC; 

This works great for me:

public void clear() {
    int size = data.size();
    if (size > 0) {
        for (int i = 0; i < size; i++) {
            data.remove(0);
        }

        notifyItemRangeRemoved(0, size);
    }
}

Source: https://github.com/mikepenz/LollipopShowcase/blob/master/app/src/main/java/com/mikepenz/lollipopshowcase/adapter/ApplicationAdapter.java

or:

public void clear() {
    int size = data.size();
    data.clear();
    notifyItemRangeRemoved(0, size);
}

For you:

@Override
protected void onRestart() {
    super.onRestart();

    // first clear the recycler view so items are not populated twice
    recyclerAdapter.clear();

    // then reload the data
    PostCall doPostCall = new PostCall(); // my AsyncTask... 
    doPostCall.execute();
}

I recently had a similar problem. You can install node_modules elsewhere and set the NODE_PATH environment variable.

In the example below I installed node_modules into /install

worker/Dockerfile

FROM node:0.12

RUN ["mkdir", "/install"]

ADD ["./package.json", "/install"]
WORKDIR /install
RUN npm install --verbose
ENV NODE_PATH=/install/node_modules

WORKDIR /worker

COPY . /worker/

docker-compose.yml

redis:
    image: redis
worker:
    build: ./worker
    command: npm start
    ports:
        - "9730:9730"
    volumes:
        - worker/:/worker/
    links:
        - redis

I've created an example to show how to. Updated state definition would be:

  $stateProvider
    .state('home', {
      url: '/:foo?bar',
      views: {
        '': {
          templateUrl: 'tpl.home.html',
          controller: 'MainRootCtrl'

        },
        ...
      }

And this would be the controller:

.controller('MainRootCtrl', function($scope, $state, $stateParams) {
    //..
    var foo = $stateParams.foo; //getting fooVal
    var bar = $stateParams.bar; //getting barVal
    //..
    $scope.state = $state.current
    $scope.params = $stateParams; 
})

What we can see is that the state home now has url defined as:

url: '/:foo?bar',

which means, that the params in url are expected as

/fooVal?bar=barValue

These two links will correctly pass arguments into the controller:

<a ui-sref="home({foo: 'fooVal1', bar: 'barVal1'})">
<a ui-sref="home({foo: 'fooVal2', bar: 'barVal2'})">

Also, the controller does consume $stateParams instead of $stateParam.

Link to doc:

• URL Parameters

You can check it here

params : {}

There is also new, more granular setting params : {}. As we've already seen, we can declare parameters as part of url. But with params : {} configuration - we can extend this definition or even introduce paramters which are not part of the url:

.state('other', {
    url: '/other/:foo?bar',
    params: { 
        // here we define default value for foo
        // we also set squash to false, to force injecting
        // even the default value into url
        foo: {
          value: 'defaultValue',
          squash: false,
        },
        // this parameter is now array
        // we can pass more items, and expect them as []
        bar : { 
          array : true,
        },
        // this param is not part of url
        // it could be passed with $state.go or ui-sref 
        hiddenParam: 'YES',
      },
    ...

Settings available for params are described in the documentation of the $stateProvider

Below is just an extract

• value - {object|function=}: specifies the default value for this parameter. This implicitly sets this parameter as optional...
• array - {boolean=}: (default: false) If true, the param value will be treated as an array of values.
• squash - {bool|string=}: squash configures how a default parameter value is represented in the URL when the current parameter value is the same as the default value.

We can call these params this way:

// hidden param cannot be passed via url
<a href="#/other/fooVal?bar=1&amp;bar=2">
// default foo is skipped
<a ui-sref="other({bar: [4,5]})">

Check it in action here

total count the documents where the value of the field is not equal to the specified value.

async function getRegisterUser() {
    return Login.count({"role": { $ne: 'Super Admin' }}, (err, totResUser) => {
        if (err) {
            return err;
        }
        return totResUser;
    })
}

Goto workspace/rtc-ws/.metadata/.plugins/org.eclipse.m2e.core/lifecycle-mapping-metadata.xml then create lifecycle-mapping-metadata.xml file and paste below and reload configuration as below

If you are using Eclipse 4.2 and have troubles with mapping and won't put mess into yours pom.xml create new file lifecycle-mapping-metadata.xml configure it in Windows -> Preferences -> Lifecycle mapping (don't forget press Reload workspace lifecycle mappings metadata after each change of this file!). Here is example based on eclipse/plugins/org.eclipse.m2e.lifecyclemapping.defaults_1.2.0.20120903-1050.jar/lifecycle-mapping-metadata.xml

I've always kept this around in a util file. You can use it as a mixin on your own classes too.

class dotdict(dict):
    """dot.notation access to dictionary attributes"""
    __getattr__ = dict.get
    __setattr__ = dict.__setitem__
    __delattr__ = dict.__delitem__

mydict = {'val':'it works'}
nested_dict = {'val':'nested works too'}
mydict = dotdict(mydict)
mydict.val
# 'it works'

mydict.nested = dotdict(nested_dict)
mydict.nested.val
# 'nested works too'

This would be a simpler approach

#over > img{
    display: block;
    margin:0 auto; 
}

I would remove them. In my book, dead code like that should be considered errors because it makes you do a double-take and ask yourself "How would I ever execute that line?"

You don't need to go to 64-bit to see something like this. Consider int32_t on common 32-bit platforms. It might be typedef'ed as int or as a long, but obviously only one of the two at a time. int and long are of course distinct types.

It's not hard to see that there is no workaround which makes int == int32_t == long on 32-bit systems. For the same reason, there's no way to make long == int64_t == long long on 64-bit systems.

If you could, the possible consequences would be rather painful for code that overloaded foo(int), foo(long) and foo(long long) - suddenly they'd have two definitions for the same overload?!

The correct solution is that your template code usually should not be relying on a precise type, but on the properties of that type. The whole same_type logic could still be OK for specific cases:

long foo(long x);
std::tr1::disable_if(same_type(int64_t, long), int64_t)::type foo(int64_t);

I.e., the overload foo(int64_t) is not defined when it's exactly the same as foo(long).

[edit] With C++11, we now have a standard way to write this:

long foo(long x);
std::enable_if<!std::is_same<int64_t, long>::value, int64_t>::type foo(int64_t);

[edit] Or C++20

long foo(long x);
int64_t foo(int64_t) requires (!std::is_same_v<int64_t, long>);

You can list down the entries (certificates details) with the keytool and even you don't need to mention the store type.

keytool -list -v -keystore cert.p12 -storepass <password>

 Keystore type: PKCS12
 Keystore provider: SunJSSE

 Your keystore contains 1 entry
 Alias name: 1
 Creation date: Jul 11, 2020
 Entry type: PrivateKeyEntry
 Certificate chain length: 2

To do it in a Java file:

EditText input = new EditText(this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);

You can use code like this:

char *MyFunction(some arguments...)
{
    char *pointer = malloc(size for the new array);
    if (!pointer)
        An error occurred, abort or do something about the error.
    return pointer; // Return address of memory to the caller.
}

When you do this, the memory should later be freed, by passing the address to free.

There are other options. A routine might return a pointer to an array (or portion of an array) that is part of some existing structure. The caller might pass an array, and the routine merely writes into the array, rather than allocating space for a new array.

Why you are using row.Cells[row.Index]. You need to specify index of column you want to search (Problem #2). For example, you need to change row.Cells[row.Index] to row.Cells[2] where 2 is index of your column:

private void btnSearch_Click(object sender, EventArgs e)
{
    string searchValue = textBox1.Text;

    dgvProjects.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
    try
    {
        foreach (DataGridViewRow row in dgvProjects.Rows)
        {
            if (row.Cells[2].Value.ToString().Equals(searchValue))
            {
                row.Selected = true;
                break;
            }
        }
    }
    catch (Exception exc)
    {
        MessageBox.Show(exc.Message);
    }
}

ConfigurationManager.AppSettings returns the settings defined for the application, not for the specific DLL, you can access them but it's the application settings that will be returned.

If you're using you dll from another application then the ConnectionString shall be in the app.settings of the application.

Check the server configuration and folders' routes:

1. Open servers view (Window -> Open view... -> Others... -> Search for 'servers'.

2. Right click on server (mine is Tomcat v6.0) -> properties -> Click on 'Swicth Location' (check that location's like /servers...

3. Double click on the server. This will open a new servers page. In the 'Servers Locations' area, check the 'Use Tomcat Installation (takes control of Tomcat Installation)' option.

4. Restart your server.

5. Enjoy!

Another idea using mask and CSS variables to have better control over the whole shape. It's reponsive, transparent and allow any kind of background:

.box {
  --all:0px;
  width:200px;
  height:150px;
  display:inline-block;
  margin:10px;
  background:red;
  -webkit-mask:
     linear-gradient(  45deg, transparent 0 var(--bottom-left,var(--all)) ,#fff 0) bottom left,
     linear-gradient( -45deg, transparent 0 var(--bottom-right,var(--all)),#fff 0) bottom right,
     linear-gradient( 135deg, transparent 0 var(--top-left,var(--all))    ,#fff 0) top left,
     linear-gradient(-135deg, transparent 0 var(--top-right,var(--all))   ,#fff 0) top right;
   -webkit-mask-size:50.5% 50.5%;
   -webkit-mask-repeat:no-repeat;
}


body {
  background:grey;
}

<div class="box" style="--top-left:20px"></div>
<div class="box" style="--top-right:20px;--bottom-right:50px;background:radial-gradient(red,yellow)"></div>
<div class="box" style="--all:30px;background:url(https://picsum.photos/id/104/200/200)"></div>
<div class="box" style="--all:30px;--bottom-right:0px;background:linear-gradient(red,blue)"></div>
<div class="box" style="--all:50%;width:150px;background:green"></div>
<div class="box" style="--all:12%;width:150px;background:repeating-linear-gradient(45deg,#000 0 10px,#fff 0 20px)"></div>

And below in case you want to consider border:

.box {
  --all:0px;
  --b:pink;
  
  width:200px;
  height:150px;
  display:inline-block;
  margin:10px;
  border:5px solid var(--b);
  background:
     linear-gradient(  45deg, var(--b) 0 calc(var(--bottom-left,var(--all)) + 5px) ,transparent 0) bottom left /50% 50%,
     linear-gradient( -45deg, var(--b) 0 calc(var(--bottom-right,var(--all)) + 5px),transparent 0) bottom right/50% 50%,
     linear-gradient( 135deg, var(--b) 0 calc(var(--top-left,var(--all)) + 5px)    ,transparent 0) top left    /50% 50%,
     linear-gradient(-135deg, var(--b) 0 calc(var(--top-right,var(--all)) + 5px)   ,transparent 0) top right   /50% 50%,
     var(--img,red);
  background-origin:border-box;
  background-repeat:no-repeat;
  -webkit-mask:
     linear-gradient(  45deg, transparent 0 var(--bottom-left,var(--all)) ,#fff 0) bottom left,
     linear-gradient( -45deg, transparent 0 var(--bottom-right,var(--all)),#fff 0) bottom right,
     linear-gradient( 135deg, transparent 0 var(--top-left,var(--all))    ,#fff 0) top left,
     linear-gradient(-135deg, transparent 0 var(--top-right,var(--all))   ,#fff 0) top right;
   -webkit-mask-size:50.5% 50.5%;
   -webkit-mask-repeat:no-repeat;
}


body {
  background:grey;
}

<div class="box" style="--top-left:20px"></div>
<div class="box" style="--top-right:20px;--bottom-right:50px;--img:radial-gradient(red,yellow);--b:white;"></div>
<div class="box" style="--all:30px;--img:url(https://picsum.photos/id/104/200/200) center/cover;--b:orange;"></div>
<div class="box" style="--all:30px;--bottom-right:0px;--img:linear-gradient(red,blue)"></div>

<div class="box" style="--all:12%;width:150px;--img:repeating-linear-gradient(45deg,#000 0 10px,#fff 0 20px)"></div>

Let's also add some radius:

.box {
  --all:0px;
  --b:pink;
  
  width:200px;
  height:150px;
  display:inline-block;
  margin:10px;
  filter:url(#round);
}
.box::before {
  content:"";
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:0;
  background:var(--img,red);
  -webkit-mask:
     linear-gradient(  45deg, transparent 0 var(--bottom-left,var(--all)) ,#fff 0) bottom left,
     linear-gradient( -45deg, transparent 0 var(--bottom-right,var(--all)),#fff 0) bottom right,
     linear-gradient( 135deg, transparent 0 var(--top-left,var(--all))    ,#fff 0) top left,
     linear-gradient(-135deg, transparent 0 var(--top-right,var(--all))   ,#fff 0) top right;
   -webkit-mask-size:50.5% 50.5%;
   -webkit-mask-repeat:no-repeat;
}

It seems you don't import jquery. Those $ functions come with this non standard (but very useful) library.

Read the tutorial there : http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery It starts with how to import the library.

Regarding building a DLL using MinGW, here are some very brief instructions.

First, you need to mark your functions for export, so they can be used by callers of the DLL. To do this, modify them so they look like (for example)

__declspec( dllexport ) int add2(int num){
   return num + 2;
}

then, assuming your functions are in a file called funcs.c, you can compile them:

gcc -shared -o mylib.dll funcs.c

The -shared flag tells gcc to create a DLL.

To check if the DLL has actually exported the functions, get hold of the free Dependency Walker tool and use it to examine the DLL.

For a free IDE which will automate all the flags etc. needed to build DLLs, take a look at the excellent Code::Blocks, which works very well with MinGW.

Edit: For more details on this subject, see the article Creating a MinGW DLL for Use with Visual Basic on the MinGW Wiki.

If it's really important that you have the correct date and time; it's best to have a service on your server (which you of course have running in UTC) that returns the time. You can then create a new Date on the client and compare the values and if necessary adjust all dates with the offset from the server time.

Why do this? I've had bug reports that was hard to reproduce because I could not find the error messages in the server log, until I noticed that the bug report was mailed two days after I'd received it. You can probably trust the browser to correctly handle time-zone conversion when being sent a UTC timestamp, but you obviously cannot trust the users to have their system clock correctly set. (If the users have their timezone incorrectly set too, there is not really any solution; other than printing the current server time in "local" time)

document.getElementById("fName").style.border="1px solid black";

From the Java interface design FAQ by Philip Shaw:

Interface variables are static because Java interfaces cannot be instantiated in their own right; the value of the variable must be assigned in a static context in which no instance exists. The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned by program code.

Not sure if this one got mentioned yet but the ThreadStatic attribute is a realy useful one. This makes a static field static just for the current thread.

[ThreadStatic]
private static int _ThreadStaticInteger;

You should not include an initializer because it only get executed once for the entire application, you're better off making the field nullable and checking if the value is null before you use it.

And one more thing for ASP.NET applications threads are reused so if you modify the value it could end up being used for another page request.

Still I have found this useful on several occasions. For example in creating a custom transaction class that:

using (DbTransaction tran = new DbTransaction())
{
    DoQuery("...");
    DoQuery("...");    
}

The DbTransaction constructor sets a ThreadStatic field to its self and resets it to null in the dispose method. DoQuery checks the static field and if != null uses the current transaction if not it defaults to something else. We avoid having to pass the transaction to each method plus it makes it easy to wrap other methods that were not originaly meant to be used with transaction inside a transaction ...

Just one use :)

Make sure the script is placed in the bottom of the BODY element of the document you're trying to manipulate, not in the HEAD element or placed before any of the elements you want to "get".

It does not matter if you import the script or if it's inline, the important thing is the placing. You don't have to put the command inside a function either; while it's good practice you can just call it directly, it works just fine.

To add to x4u answer, which gives you the floor of the binary log of a number, this function return the ceil of the binary log of a number :

public static int ceilbinlog(int number) // returns 0 for bits=0
{
    int log = 0;
    int bits = number;
    if ((bits & 0xffff0000) != 0) {
        bits >>>= 16;
        log = 16;
    }
    if (bits >= 256) {
        bits >>>= 8;
        log += 8;
    }
    if (bits >= 16) {
        bits >>>= 4;
        log += 4;
    }
    if (bits >= 4) {
        bits >>>= 2;
        log += 2;
    }
    if (1 << log < number)
        log++;
    return log + (bits >>> 1);
}

Alternative way to check would be:

if (!$('#myModal').is(':visible')) {
    // if modal is not shown/visible then do something
}

I had this happen in Visual Studio 2015 too for an interesting reason. Just adding it here in case it happens to someone else.

I already had number of files in project and I was adding another one that would have main function in it, however when I initially added the file I made a typo in the extension (.coo instead of .cpp). I corrected that but when I was done I got this error. It turned out that Visual Studio was being smart and when file was added it decided that it is not a source file due to the initial extension.

Right-clicking on file in solution explorer and selecting Properties -> General -> ItemType and setting it to "C/C++ compiler" fixed the issue.

Have you tried:

echo "12|23|11" | awk '{split($0,a,"|"); print a[3],a[2],a[1]}'

is the ajax uploader refreshing your input element? if so you should consider using .live() method.

 $('#imageFile').live('change', function(){ uploadFile(); });

update:

from jQuery 1.7+ you should use now .on()

 $(parent_element_selector_here or document ).on('change','#imageFile' , function(){ uploadFile(); });

If I use Firefox then screen.width and screen.height works fine but in IE and Chrome they don't work properly instead it opens with the minimum size.

And yes I tried giving too large numbers too like 10000 for both height and width but not exactly the maximized effect.

this worked perfectly for me:

for(a in array)console.log(array[a])

you can extract any array created in console for find/replace cleanup and posterior usage of this data extracted

I like a lot of answers, particularly @saineshwar 's one. I'm using .net Core 3.0 with AutoMapper 9.0, so I feel it's time to update its answer.

What worked for me was in Startup.ConfigureServices(...) register the service in this way:

    services.AddAutoMapper(cfg => cfg.AddProfile<MappingProfile>(), 
                               AppDomain.CurrentDomain.GetAssemblies());

I think that rest of @saineshwar answer keeps perfect. But if anyone is interested my controller code is:

[HttpGet("{id}")]
public async Task<ActionResult> GetIic(int id)
{
    // _context is a DB provider
    var Iic = await _context.Find(id).ConfigureAwait(false);

    if (Iic == null)
    {
        return NotFound();
    }

    var map = _mapper.Map<IicVM>(Iic);

    return Ok(map);
}

And my mapping class:

public class MappingProfile : Profile
{
    public MappingProfile()
    {
        CreateMap<Iic, IicVM>()
            .ForMember(dest => dest.DepartmentName, o => o.MapFrom(src => src.Department.Name))
            .ForMember(dest => dest.PortfolioTypeName, o => o.MapFrom(src => src.PortfolioType.Name));
            //.ReverseMap();
    }
}

----- EDIT -----

After reading the docs linked in the comments by Lucian Bargaoanu, I think it's better to change this answer a bit.

The parameterless services.AddAutoMapper() (that had the @saineshwar answer) doesn't work anymore (at least for me). But if you use the NuGet assembly AutoMapper.Extensions.Microsoft.DependencyInjection, the framework is able to inspect all the classes that extend AutoMapper.Profile (like mine, MappingProfile).

So, in my case, where the class belong to the same executing assembly, the service registration can be shortened to services.AddAutoMapper(System.Reflection.Assembly.GetExecutingAssembly());
(A more elegant approach could be a parameterless extension with this coding).

Thanks, Lucian!

As mentioned above BOOL could be an unsigned char type depending on your architecture, while bool is of type int. A simple experiment will show the difference why BOOL and bool can behave differently:

bool ansicBool = 64;
if(ansicBool != true) printf("This will not print\n");

printf("Any given vlaue other than 0 to ansicBool is evaluated to %i\n", ansicBool);

BOOL objcBOOL = 64;
if(objcBOOL != YES) printf("This might print depnding on your architecture\n");

printf("BOOL will keep whatever value you assign it: %i\n", objcBOOL);

if(!objcBOOL) printf("This will not print\n");

printf("! operator will zero objcBOOL %i\n", !objcBOOL);

if(!!objcBOOL) printf("!! will evaluate objcBOOL value to %i\n", !!objcBOOL);

To your surprise if(objcBOOL != YES) will evaluates to 1 by the compiler, since YES is actually the character code 1, and in the eyes of compiler, character code 64 is of course not equal to character code 1 thus the if statement will evaluate to YES/true/1 and the following line will run. However since a none zero bool type always evaluates to the integer value of 1, the above issue will not effect your code. Below are some good tips if you want to use the Objective-C BOOL type vs the ANSI C bool type:

• Always assign the YES or NO value and nothing else.
• Convert BOOL types by using double not !! operator to avoid unexpected results.
• When checking for YES use if(!myBool) instead of if(myBool != YES) it is much cleaner to use the not ! operator and gives the expected result.

Wow, no really reusable solutions among answers yet.. I mean, a standart event handler should get only an event argument and doesn't have to use ids at all.. I'd use:

function handleSelectChange(event) {

    // if you want to support some really old IEs, add
    // event = event || window.event;

    var selectElement = event.target;

    var value = selectElement.value;
    // to support really old browsers, you may use
    // selectElement.value || selectElement.options[selectElement.selectedIndex].value;
    // like el Dude has suggested

    // do whatever you want with value
}

You may use this handler with each – inline js:

<select onchange="handleSelectChange(event)">
    <option value="1">one</option>
    <option value="2">two</option>
</select>

jQuery:

jQuery('#select_id').on('change',handleSelectChange);

or vanilla JS handler setting:

var selector = document.getElementById("select_id");
selector.onchange = handleSelectChange;
// or
selector.addEventListener('change', handleSelectChange);

And don't have to rewrite this for each select element you have.

Example snippet:

function handleSelectChange(event) {_x000D_
_x000D_
    var selectElement = event.target;_x000D_
    var value = selectElement.value;_x000D_
    alert(value);_x000D_
}

<select onchange="handleSelectChange(event)">_x000D_
    <option value="1">one</option>_x000D_
    <option value="2">two</option>_x000D_
</select>

I prefer following way to check whether rows contain any NAs:

row.has.na <- apply(final, 1, function(x){any(is.na(x))})

This returns logical vector with values denoting whether there is any NA in a row. You can use it to see how many rows you'll have to drop:

sum(row.has.na)

and eventually drop them

final.filtered <- final[!row.has.na,]

For filtering rows with certain part of NAs it becomes a little trickier (for example, you can feed 'final[,5:6]' to 'apply'). Generally, Joris Meys' solution seems to be more elegant.

This is the solution that I came up with trying to solve this problem for myself in order to systematically produce \n's as separators. It writes using a list of strings where each string is one line of the file, however it seems that it may work for you as well. (Python 3.+)

#Takes a list of strings and prints it to a file.
def writeFile(file, strList):
    line = 0
    lines = []
    while line < len(strList):
        lines.append(cheekyNew(line) + strList[line])
        line += 1
    file = open(file, "w")
    file.writelines(lines)
    file.close()

#Returns "\n" if the int entered isn't zero, otherwise "".
def cheekyNew(line):
    if line != 0:
        return "\n"
    return ""

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>

We face this error when permanent generation heap is full and some of us we use command prompt to build our maven project in windows. since we need to increase heap size, we could set our environment variable @ControlPanel/System and Security/System and there you click on Change setting and select Advanced and set Environment variable as below

• Variable-name : MAVEN_OPTS
• Variable-value : -XX:MaxPermSize=128m

best solution

install aria2c in system &

 echo exec("aria2c \"$url\"")

More clear example with es6 destructing

class Form extends Component {
    constructor(props) {
        super(props);
        this.state = {
            login: null,
            password: null,
            email: null
        }
    }

    onChange(e) {
        this.setState({
            [e.target.name]: e.target.value
        })
    }

    onSubmit(e) {
        e.preventDefault();
        let login = this.state.login;
        let password = this.state.password;
        // etc
    }

    render() {
        return (
            <form onSubmit={this.onSubmit.bind(this)}>
                <input type="text" name="login" onChange={this.onChange.bind(this)} />
                <input type="password" name="password" onChange={this.onChange.bind(this)} />
                <input type="email" name="email" onChange={this.onChange.bind(this)} />
                <button type="submit">Sign Up</button>
            </form>
        );
    }
}

In this simple example you can just put synchronized as a modifier after public in both method signatures.

More complex scenarios require other stuff.

select a.* , b.Aa , b.Ab, b.Ac from table1 a left join table2 b on a.id=b.id

this should select all columns from table 1 and only the listed columns from table 2 joined by id.

With an OR (||) operation, if any one of the conditions are true, the result is true.

I think you want an AND (&&) operation here.

In your HTML code

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

In your Typescript code

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

This works perfectly, it does not give any error.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

Using jQuery:

$('td:contains("male")')

I found that following these instructions helped with finding what the problem was. For me, that was the killer, not knowing what was broken.

http://mythinkpond.wordpress.com/2011/07/01/tomcat-6-infamous-severe-error-listenerstart-message-how-to-debug-this-error/

Quoting from the link

In Tomcat 6 or above, the default logger is the”java.util.logging” logger and not Log4J. So if you are trying to add a “log4j.properties” file – this will NOT work. The Java utils logger looks for a file called “logging.properties” as stated here: http://tomcat.apache.org/tomcat-6.0-doc/logging.html

So to get to the debugging details create a “logging.properties” file under your”/WEB-INF/classes” folder of your WAR and you’re all set.

And now when you restart your Tomcat, you will see all of your debugging in it’s full glory!!!

Sample logging.properties file:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

if(A == "haha" && B == "hihi") {
//hahahihi?
}

if(A == "haha" || B != "hihi") {
//hahahihi!?
}

This may happen because of the old and new IP address I have faced same issue which was solve by below method:

vim /etc/zabbix/web/zabbix.conf.php

$ZBX_SERVER = new ip address

then restart zabbix server

This is not exactly an answer, rather sharing my findings, and hopefully getting some critical argument for/against it, as specifically I am not aware how efficient it is.

I recently had a need to do this for my project. I did this using Object.assign, more precisely it is done something like this:Object.assign(new Person(...), anObjectLikePerson).

Here is link to my JSFiddle, and also the main part of the code:

function Person(firstName, lastName) {
  this.firstName = firstName;
  this.lastName = lastName;

  this.getFullName = function() {
    return this.lastName + ' ' + this.firstName;
  }
}

var persons = [{
  lastName: "Freeman",
  firstName: "Gordon"
}, {
  lastName: "Smith",
  firstName: "John"
}];

var stronglyTypedPersons = [];
for (var i = 0; i < persons.length; i++) {
  stronglyTypedPersons.push(Object.assign(new Person("", ""), persons[i]));
}

'some+multi+word+string'.replace(/\+/g, ' ');
                                   ^^^^^^

'g' = "global"

Cheers

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

^[A-Za-z0-9_.]+$

From beginning until the end of the string, match one or more of these characters.

Edit:

Note that ^ and $ match the beginning and the end of a line. When multiline is enabled, this can mean that one line matches, but not the complete string.

Use \A for the beginning of the string, and \z for the end.

See for example: http://msdn.microsoft.com/en-us/library/h5181w5w(v=vs.110).aspx

Just chain them together:

.a.b {
  color: #666;
}

Yeeeaaahhh.... you can now use var() function in CSS.....

The good news is you can change it using JavaScript access, which will change globally as well...

But how to declare them...

It's quite simple:

For example, you wanna assign a #ff0000 to a var(), just simply assign it in :root, also pay attention to --:

:root {
    --red: #ff0000; 
}

html, body {
    background-color: var(--red); 
}

The good things are the browser support is not bad, also don't need to be compiled to be used in the browser like LESS or SASS...

Also, here is a simple JavaScript script, which changes the red value to blue:

const rootEl = document.querySelector(':root');
root.style.setProperty('--red', 'blue');

As of October 3, 2012, a new "Elastic Beanstalk for Java with Apache Tomcat 7" Linux x64 AMI deployed with the Sample Application has the install here:

/etc/tomcat7/

The /etc/tomcat7/tomcat7.conf file has the following settings:

# Where your java installation lives
JAVA_HOME="/usr/lib/jvm/jre"

# Where your tomcat installation lives
CATALINA_BASE="/usr/share/tomcat7"
CATALINA_HOME="/usr/share/tomcat7"
JASPER_HOME="/usr/share/tomcat7"
CATALINA_TMPDIR="/var/cache/tomcat7/temp"

I had to use the "=" binding instead of "&" because that was not working. Strange behavior.

HTML5 says <input type="file" accept="image/*">. Of course, never trust client-side validation: Always check again on the server-side...

Encrypt something with the public key, and see which private key decrypts it.

This Code Project article by none other than Jeff Atwood implements a simplified wrapper around the .NET cryptography classes. Assuming these keys were created for use with RSA, use the asymmetric class with your public key to encrypt, and the same with your private key to decrypt.

str.replace(/\s/g,'')

Works for me.

jQuery.trim has the following hack for IE, although I'm not sure what versions it affects:

// Check if a string has a non-whitespace character in it
rnotwhite = /\S/

// IE doesn't match non-breaking spaces with \s
if ( rnotwhite.test( "\xA0" ) ) {
    trimLeft = /^[\s\xA0]+/;
    trimRight = /[\s\xA0]+$/;
}

Most of the time this compile error comes when unicode(UTF-8 encoded) file compiling

javac -encoding UTF-8 HelloWorld.java

and also You can add this compile option to your IDE ex: Intellij idea
(File>settings>Java Compiler) add as additional command line parameter

-encoding : encoding Set the source file encoding name, such as EUC-JP and UTF-8.. If -encoding is not specified, the platform default converter is used. (DOC)

If you use EcmaScript version >= 5.1, you can implement a functional version of chunk() using array.reduce() that has O(N) complexity:

function chunk(chunkSize, array) {_x000D_
    return array.reduce(function(previous, current) {_x000D_
        var chunk;_x000D_
        if (previous.length === 0 || _x000D_
                previous[previous.length -1].length === chunkSize) {_x000D_
            chunk = [];   // 1_x000D_
            previous.push(chunk);   // 2_x000D_
        }_x000D_
        else {_x000D_
            chunk = previous[previous.length -1];   // 3_x000D_
        }_x000D_
        chunk.push(current);   // 4_x000D_
        return previous;   // 5_x000D_
    }, []);   // 6_x000D_
}_x000D_
_x000D_
console.log(chunk(2, ['a', 'b', 'c', 'd', 'e']));_x000D_
// prints [ [ 'a', 'b' ], [ 'c', 'd' ], [ 'e' ] ]

Explanation of each // nbr above:

1. Create a new chunk if the previous value, i.e. the previously returned array of chunks, is empty or if the last previous chunk has chunkSize items
2. Add the new chunk to the array of existing chunks
3. Otherwise, the current chunk is the last chunk in the array of chunks
4. Add the current value to the chunk
5. Return the modified array of chunks
6. Initialize the reduction by passing an empty array

Currying based on chunkSize:

var chunk3 = function(array) {
    return chunk(3, array);
};

console.log(chunk3(['a', 'b', 'c', 'd', 'e']));
// prints [ [ 'a', 'b', 'c' ], [ 'd', 'e' ] ]

You can add the chunk() function to the global Array object:

Object.defineProperty(Array.prototype, 'chunk', {_x000D_
    value: function(chunkSize) {_x000D_
        return this.reduce(function(previous, current) {_x000D_
            var chunk;_x000D_
            if (previous.length === 0 || _x000D_
                    previous[previous.length -1].length === chunkSize) {_x000D_
                chunk = [];_x000D_
                previous.push(chunk);_x000D_
            }_x000D_
            else {_x000D_
                chunk = previous[previous.length -1];_x000D_
            }_x000D_
            chunk.push(current);_x000D_
            return previous;_x000D_
        }, []);_x000D_
    }_x000D_
});_x000D_
_x000D_
console.log(['a', 'b', 'c', 'd', 'e'].chunk(4));_x000D_
// prints [ [ 'a', 'b', 'c' 'd' ], [ 'e' ] ]

The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).

Your reference to "0x31 = 1" makes me think you're actually trying to convert ASCII values to strings - in which case you should be using something like Encoding.ASCII.GetString(Byte[])

Maybe this can help

string input = "hello123world";
bool isDigitPresent = input.Any(c => char.IsDigit(c));

answer from msdn.

One option would be

const styleElement = getComputedStyle(document.getElementById("myDiv"));
console.log(styleElement.height);

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.

If you use Express, express-mailerwrapsnodemailervery nicely and is very easy to use:

//# config/mailer.js    
module.exports = function(app) {
  if (!app.mailer) {
    var mailer = require('express-mailer');
    console.log('[MAIL] Mailer using user ' + app.config.mail.auth.user);

Quick Start

Run:

rsync -av --exclude='path1/in/source' --exclude='path2/in/source' [source]/ [destination]

Notes

• -avr will create a new directory named [destination].
• source and source/ create different results:
  • source — copy the contents of source into destination.
  • source/ — copy the folder source into destination.
• To exclude many files:
  • --exclude-from=FILE — FILE is the name of a file containing other files or directories to exclude.
• --exclude may also contain wildcards:
  • e.g. --exclude=*/.svn*

Modified from: https://stackoverflow.com/a/2194500/749232

Example

Starting folder structure:

.
+-- destination
+-- source
    +-- fileToCopy.rtf
    +-- fileToExclude.rtf

Run:

rsync -av --exclude='fileToCopy.rtf' source/ destination

Ending folder structure:

.
+-- destination
¦   +-- fileToExclude.rtf
+-- source
    +-- fileToCopy.rtf
    +-- fileToExclude.rtf

For those who want to add multiple Python version in their system: I easily add multiple interpreters by running the following commands:

• sudo apt update
• sudo apt install software-properties-common
• sudo add-apt-repository ppa:deadsnakes/ppa
• sudo apt install python 3.x.x
• then while making your virtual environment choose the interpreter of your choice.

If you are using an ActionBarActivity then you can tell Android to use the Toolbar as the ActionBar like so:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);

And then calls to

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);

will work. You can also use that in Fragments that are attached to ActionBarActivities you can use it like this:

((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);

If you are not using ActionBarActivities or if you want to get the back arrow on a Toolbar that's not set as your SupportActionBar then you can use the following:

mActionBar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
mActionBar.setNavigationOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
       //What to do on back clicked
   }
});

If you are using android.support.v7.widget.Toolbar, then you should add the following code to your AppCompatActivity:

@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}

If you want a specific order, then you must use an array, not an object. Objects do not have a defined order.

For example, using an array, you could do this:

var myobj = [{"A":["B"]}, {"B": ["C"]}];
var firstItem = myobj[0];

Then, you can use myobj[0] to get the first object in the array.

Or, depending upon what you're trying to do:

var myobj = [{key: "A", val:["B"]}, {key: "B",  val:["C"]}];
var firstKey = myobj[0].key;   // "A"
var firstValue = myobj[0].val; // "["B"]

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

There is a project called Open Traffic which is not fully functional right now but seems to be the right answer in the future.

OpenTraffic is a global data platform to process anonymous positions of vehicles and smartphones into real-time and historical traffic statistics. We're building this in the open, using fully open-source software, with involvement from a growing list of partners.

Technically you can apply styles programmatically, with custom views anyway:

private MyRelativeLayout extends RelativeLayout {
  public MyRelativeLayout(Context context) {
     super(context, null, R.style.LightStyle);
  }
}

The one argument constructor is the one used when you instantiate views programmatically.

So chain this constructor to the super that takes a style parameter.

RelativeLayout someLayout = new MyRelativeLayout(new ContextThemeWrapper(this,R.style.RadioButton));

Or as @Dori pointed out simply:

RelativeLayout someLayout = new RelativeLayout(new ContextThemeWrapper(activity,R.style.LightStyle));

Now in Kotlin:

class MyRelativeLayout @JvmOverloads constructor(
    context: Context, 
    attributeSet: AttributeSet? = null, 
    defStyleAttr: Int = R.style.LightStyle,
) : RelativeLayout(context, attributeSet, defStyleAttr)

or

 val rl = RelativeLayout(ContextThemeWrapper(activity, R.style.LightStyle))

It is simple just write java -XshowSettings:properties on your command line in windows and then paste all the files in the path shown by the java.library.path.

The difference is simple: they cause different warning messages to be emitted when compiling:

1156942.c:7:31: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int *’ [-Wformat=]
     printf("memory address = %d\n", &a); // prints "memory add=-12"
                               ^
1156942.c:8:31: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 2 has type ‘int *’ [-Wformat=]
     printf("memory address = %u\n", &a); // prints "memory add=65456"
                               ^

If you pass your pointer as a void* and use %p as the conversion specifier, then you get no error message:

#include <stdio.h>

int main()
{
    int a = 5;
    // check the memory address
    printf("memory address = %d\n", &a); /* wrong */
    printf("memory address = %u\n", &a); /* wrong */
    printf("memory address = %p\n", (void*)&a); /* right */
}

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false:

Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.

For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.

In windows, type rmdir .git or rmdir /s .git if the .git folder has subfolders.

If your git shell isn't setup with proper administrative rights (i.e. it denies you when you try to rmdir), you can open a command prompt (possibly as administrator--hit the windows key, type 'cmd', right click 'command prompt' and select 'run as administrator) and try the same commands.

rd is an alternative form of the rmdir command. http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/rmdir.mspx?mfr=true

For the go up, you just need to use scrollTop instead of scrollBottom:

$("#upClick").on("click", function () {
    scrolled = scrolled - 300;
    $(".cover").stop().animate({
        scrollTop: scrolled
    });
});

Also, use the .stop() method to stop the currently-running animation on the cover div. When .stop() is called on an element, the currently-running animation (if any) is immediately stopped.

The newest, most recent, up to date answer
This post is really old (it's 7 years old when I answered it), so no one of the other answers used the new and recommended way, which is HttpClient class.

HttpClient is considered the new API and it should replace the old ones (WebClient and WebRequest)

string url = "page url";
HttpClient client = new HttpClient();
using (HttpResponseMessage response = client.GetAsync(url).Result)
{
   using (HttpContent content = response.Content)
   {
      string result = content.ReadAsStringAsync().Result;
   }
}

for more information about how to use the HttpClient class (especially in async cases), you can refer this question

NOTE 1: If you want to use async/await

string url = "page url";
HttpClient client = new HttpClient();   // actually only one object should be created by Application
using (HttpResponseMessage response = await client.GetAsync(url))
{
   using (HttpContent content = response.Content)
   {
      string result = await content.ReadAsStringAsync();
   }
}

NOTE 2: If use C# 8 features

string url = "page url";
HttpClient client = new HttpClient();
using HttpResponseMessage response = await client.GetAsync(url);
using HttpContent content = response.Content;
string result = await content.ReadAsStringAsync();

1. Open Visual Studio Code terminal (Ctrl + `)

2. Write the Git clone command. For example,

   git clone https://github.com/angular/angular-phonecat.git
   

3. Open the folder you have just cloned (menu File → Open Folder)

   

Here:

public class Tree<T> {
    private Node<T> root;

    public Tree(T rootData) {
        root = new Node<T>();
        root.data = rootData;
        root.children = new ArrayList<Node<T>>();
    }

    public static class Node<T> {
        private T data;
        private Node<T> parent;
        private List<Node<T>> children;
    }
}

That is a basic tree structure that can be used for String or any other object. It is fairly easy to implement simple trees to do what you need.

All you need to add are methods for add to, removing from, traversing, and constructors. The Node is the basic building block of the Tree.

The delete operator removes a property from an object. It cannot remove a variable. So the answer to the question depends on how the global variable or property is defined.

(1) If it is created with var, it cannot be deleted.

For example:

var g_a = 1; //create with var, g_a is a variable 
delete g_a; //return false
console.log(g_a); //g_a is still 1

(2) If it is created without var, it can be deleted.

g_b = 1; //create without var, g_b is a property 
delete g_b; //return true
console.log(g_b); //error, g_b is not defined

Technical Explanation

1. Using var

In this case the reference g_a is created in what the ECMAScript spec calls "VariableEnvironment" that is attached to the current scope - this may be the a function execution context in the case of using var inside a function (though it may be get a little more complicated when you consider let) or in the case of "global" code the VariableEnvironment is attached to the global object (often window).

References in the VariableEnvironment are not normally deletable - the process detailed in ECMAScript 10.5 explains this in detail, but suffice it to say that unless your code is executed in an eval context (which most browser-based development consoles use), then variables declared with var cannot be deleted.

2. Without Using var

When trying to assign a value to a name without using the var keyword, Javascript tries to locate the named reference in what the ECMAScript spec calls "LexicalEnvironment", and the main difference is that LexicalEnvironments are nested - that is a LexicalEnvironment has a parent (what the ECMAScript spec calls "outer environment reference") and when Javascript fails to locate the reference in a LexicalEnvironment, it looks in the parent LexicalEnvironment (as detailed in 10.3.1 and 10.2.2.1). The top level LexicalEnvironment is the "global environment", and that is bound to the global object in that its references are the global object's properties. So if you try to access a name that was not declared using a var keyword in the current scope or any outer scopes, Javascript will eventually fetch a property of the window object to serve as that reference. As we've learned before, properties on objects can be deleted.

Notes

1. It is important to remember that var declarations are "hoisted" - i.e. they are always considered to have happened in the beginning of the scope that they are in - though not the value initialization that may be done in a var statement - that is left where it is. So in the following code, a is a reference from the VariableEnvironment and not the window property and its value will be 10 at the end of the code:

   function test() { a = 5; var a = 10; }
   

2. The above discussion is when "strict mode" is not enabled. Lookup rules are a bit different when using "strict mode" and lexical references that would have resolved to window properties without "strict mode" will raise "undeclared variable" errors under "strict mode". I didn't really understand where this is specified, but its how browsers behave.

You can memcpy structs, or you can just assign them like any other value.

struct {int a, b;} c, d;
c.a = c.b = 10;
d = c;

A literally insane answer, but if you have some kind of replication system set up (for a system with a billion rows, I hope you do), you can use a rough-estimator (like MAX(pk)), divide that value by the number of slaves you have, run several queries in parallel.

For the most part, you'd partition the queries across slaves based on the best key (or the primary key I guess), in such a way (we're going to use 250000000 as our Rows / Slaves):

-- First slave
SELECT COUNT(pk) FROM t WHERE pk < 250000000
-- Ith slave where 2 <= I <= N - 1
SELECT COUNT(pk) FROM t WHERE pk >= I*250000000 and pk < (I+1)*250000000
-- Last slave
SELECT COUNT(pk) FROM t WHERE pk > (N-1)*250000000

But you need SQL only. What a bust. Ok, so let's say you're a sadomasochist. On the master (or closest slave) you'd most likely need to create a table for this:

CREATE TABLE counter_table (minpk integer, maxpk integer, cnt integer, slaveid integer)

So instead of only having the selects running in your slaves, you'd have to do an insert, akin to this:

INSERT INTO counter_table VALUES (I*25000000, (I+1)*250000000, (SELECT COUNT(pk) FROM ... ), @@SLAVE_ID)

You may run into issues with slaves writing to a table on master. You may need to get even more sadis- I mean, creative:

-- A table per slave!
INSERT INTO counter_table_slave_I VALUES (...)

You should in the end have a slave that exists last in the path traversed by the replication graph, relative to the first slave. That slave should now have all other counter values, and should have its own values. But by the time you've finished, there probably are rows added, so you'd have to insert another one compensating for the recorded max pk in your counter_table and the current max pk.

At that point, you'd have to do an aggregate function to figure out what the total rows are, but that's easier since you'd be running it on at most the "number of slaves you have and change" rows.

If you're in the situation where you have separate tables in the slaves, you can UNION to get all the rows you need.

SELECT SUM(cnt) FROM (
    SELECT * FROM counter_table_slave_1
      UNION
    SELECT * FROM counter_table_slave_2
      UNION
    ...
  )

Or you know, be a bit less insane and migrate your data to a distributed processing system, or maybe use a Data Warehousing solution (which will give you awesome data crunching in the future too).

Do note, this does depend on how well your replication is set up. Since the primary bottleneck will most likely be persistent storage, if you have cruddy storage or poorly segregated data stores with heavy neighbor noise, this will probably run you slower than just waiting for a single SELECT COUNT(*) ...

But if you have good replication, then your speed gains should be directly related to the number or slaves. In fact, if it takes 10 minutes to run the counting query alone, and you have 8 slaves, you'd cut your time to less than a couple minutes. Maybe an hour to iron out the details of this solution.

Of course, you'd never really get an amazingly accurate answer since this distributed solving introduces a bit of time where rows can be deleted and inserted, but you can try to get a distributed lock of rows at the same instance and get a precise count of the rows in the table for a particular moment in time.

Actually, this seems impossible, since you're basically stuck with an SQL-only solution, and I don't think you're provided a mechanism to run a sharded and locked query across multiple slaves, instantly. Maybe if you had control of the replication log file... which means you'd literally be spinning up slaves for this purpose, which is no doubt slower than just running the count query on a single machine anyway.

So there's my two 2013 pennies.

Call this method to change app locale:

public void settingLocale(Context context, String language) {

    Locale locale;

    Configuration config = new Configuration();

     if(language.equals(LANGUAGE_ENGLISH)) {

        locale = new Locale("en");

        Locale.setDefault(locale);

        config.locale = locale;

    }else if(language.equals(LANGUAGE_ARABIC)){

        locale = new Locale("hi");

        Locale.setDefault(locale);

        config.locale = locale;

    }

    context.getResources().updateConfiguration(config, null);

    // Here again set the text on view to reflect locale change

    // and it will pick resource from new locale

    tv1.setText(R.string.one); //tv1 is textview in my activity

}

Note: Put your strings in value and values- folder.

If you are using Constraint Layout, you can set any view inside it, to fill a percentage of the screen with:

layout_constraintWidth_percent="0.8"

So, for example, if you have a ScrollView inside the dialog and you want to set it to a percentage of the screen height. It would be like this:

<ScrollView
            android:id="@+id/scrollView"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintHeight_percent="0.8">

Hope it helps someone !!

Here is PostgreSQL example without trigger if someone need it on PostgreSQL:

CREATE SEQUENCE messages_seq;

 CREATE TABLE IF NOT EXISTS messages (
    id CHAR(20) NOT NULL DEFAULT ('message_' || nextval('messages_seq')),
    name CHAR(30) NOT NULL,
);

ALTER SEQUENCE messages_seq OWNED BY messages.id;

Use this code, it is working perfectly. I have create a sql function that accept two parameters, the first param is the long string that we want to search into it,and it can accept string length up to 1500 character(of course you can extend it or even change it to text datatype). And the second parameter is the substring that we want to calculate the number of its occurance(its length is up to 200 character, of course you can change it to what your need). and the output is an integer, represent the number of frequency.....enjoy it.

CREATE FUNCTION [dbo].[GetSubstringCount]
(
  @InputString nvarchar(1500),
  @SubString NVARCHAR(200)
)
RETURNS int
AS
BEGIN 
        declare @K int , @StrLen int , @Count int , @SubStrLen int 
        set @SubStrLen = (select len(@SubString))
        set @Count = 0
        Set @k = 1
        set @StrLen =(select len(@InputString))
    While @K <= @StrLen
        Begin
            if ((select substring(@InputString, @K, @SubStrLen)) = @SubString)
                begin
                    if ((select CHARINDEX(@SubString ,@InputString)) > 0)
                        begin
                        set @Count = @Count +1
                        end
                end
                                Set @K=@k+1
        end
        return @Count
end

Assuming you have an ArrayList that contains characters, you could do this:

List<Character> list = new ArrayList<Character>();
list.addAll(Arrays.asList('+', '-', '*', '^'));

select distinct 'GRANT '||privilege||' ON '||OWNER||'.'||TABLE_NAME||' TO '||RP.GRANTEE
from DBA_ROLE_PRIVS RP join ROLE_TAB_PRIVS RTP 
on (RP.GRANTED_ROLE = RTP.role)  
where (OWNER in ('YOUR USER') --Change User Name
   OR RP.GRANTEE in ('YOUR USER')) --Change User Name
and RP.GRANTEE not in ('SYS', 'SYSTEM')
;

Simple date example using $filter in a controller would be:

var myDate = new Date();
$scope.dateAsString = $filter('date')(myDate, "yyyy-MM-dd"); 

As explained here - https://stackoverflow.com/a/20131782/262140

map isn't particularly pythonic. I would recommend using list comprehensions instead:

map(f, iterable)

is basically equivalent to:

[f(x) for x in iterable]

map on its own can't do a Cartesian product, because the length of its output list is always the same as its input list. You can trivially do a Cartesian product with a list comprehension though:

[(a, b) for a in iterable_a for b in iterable_b]

The syntax is a little confusing -- that's basically equivalent to:

result = []
for a in iterable_a:
    for b in iterable_b:
        result.append((a, b))

What about

Form1.textBox1.text = "change text";

note: 1. you have to "include" Form1 to your second form source file by using Form1;

1. textBox1 should be public

In MySQL, @variable indicates a user-defined variable. You can define your own.

SET @a = 'test';
SELECT @a;

Outside of stored programs, a variable, without @, is a system variable, which you cannot define yourself.

The scope of this variable is the entire session. That means that while your connection with the database exists, the variable can still be used.

This is in contrast with MSSQL, where the variable will only be available in the current batch of queries (stored procedure, script, or otherwise). It will not be available in a different batch in the same session.

You've nearly got it. The problem is that the Class Under Test (CUT) is not built for unit testing - it has not really been TDD'd.

Think of it like this…

• I need to test a function of a class - let's call it myFunction
• That function makes a call to a function on another class/service/database
• That function also calls another method on the CUT

In the unit test

• Should create a concrete CUT or @Spy on it
• You can @Mock all of the other class/service/database (i.e. external dependencies)
• You could stub the other function called in the CUT but it is not really how unit testing should be done

In order to avoid executing code that you are not strictly testing, you could abstract that code away into something that can be @Mocked.

In this very simple example, a function that creates an object will be difficult to test

public void doSomethingCool(String foo) {
    MyObject obj = new MyObject(foo);

    // can't do much with obj in a unit test unless it is returned
}

But a function that uses a service to get MyObject is easy to test, as we have abstracted the difficult/impossible to test code into something that makes this method testable.

public void doSomethingCool(String foo) {
    MyObject obj = MyObjectService.getMeAnObject(foo);
}

as MyObjectService can be mocked and also verified that .getMeAnObject() is called with the foo variable.

With HTML5 and without using jQuery, you can using the input event:

var input = document.querySelector('input');

input.addEventListener('input', function()
{
    console.log('input changed to: ', input.value);
});

This will fire each time the input's text changes.

Supported in IE9+ and other browsers.

Try it live in a jsFiddle here.

Can you Try:

<script type="text/javascript">_x000D_
    function go_full_screen(){_x000D_
      var elem = document.documentElement;_x000D_
      if (elem.requestFullscreen) {_x000D_
        elem.requestFullscreen();_x000D_
      } else if (elem.msRequestFullscreen) {_x000D_
        elem.msRequestFullscreen();_x000D_
      } else if (elem.mozRequestFullScreen) {_x000D_
        elem.mozRequestFullScreen();_x000D_
      } else if (elem.webkitRequestFullscreen) {_x000D_
        elem.webkitRequestFullscreen();_x000D_
      }_x000D_
    }_x000D_

My scenario is I open the project, and the local.properies shows my sdk.dir. But it keeps telling me it need the sdk from the previous other user's dir.

So I close the project and re-import the project, and everything works fine.

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:

ng update @angular/core @angular/cli

That will update your local angular version to 9. Then, just to sync material, run: ng update @angular/material

For those strictly looking for a solution that works for input or textarea, this is the simplest solution I've came across. Only a few lines of CSS and one line of JS.

The JavaScript sets a data-* attribute on the element equal to the value of the input. The input is set within a CSS grid, where that grid is a pseudo-element that uses that data-* attribute as its content. That content is what stretches the grid to the appropriate size based on the input value.

The hidden input element trick still appears to work (Chrome 43) to prevent autofill, but one thing to keep in mind is that Chrome will attempt to autofill based on the placeholder tag. You need to match the hidden input element's placeholder to that of the input you're trying to disable.

In my case, I had a field with a placeholder text of 'City or Zip' which I was using with Google Place Autocomplete. It appeared that it was attempting to autofill as if it were part of an address form. The trick didn't work until I put the same placeholder on the hidden element as on the real input:

<input style="display:none;" type="text" placeholder="City or Zip" />
<input autocomplete="off" type="text" placeholder="City or Zip" />

XML:

<foo>
   <bar>
      <type foobar="1"/>

import xml.etree.cElementTree as ET

tree = ET.parse("foo.xml")
root = tree.getroot() 
root_tag = root.tag
print(root_tag) 

for form in root.findall("./bar/type"):
    x=(form.attrib)
    z=list(x)
    for i in z:
        print(x[i])

Output:

foo

I think that equality is something that can be absolutely determined. The trouble with null is that it's inherently unknown. Null combined with any other value is null - unknown. Asking SQL "Is my value equal to null?" would be unknown every single time, even if the input is null. I think the implementation of IS NULL makes it clear.

You could put your text in a select statement such as...

SELECT 'Querying Table1' FROM dual;

This will work fast:

Case 1 - File2 = File1 + extra text appended.

grep -Fxvf File2.txt File1.txt >> File3.txt

File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

Good quote taken from a blog

The DOM component is "garbage collected", as is the JScript component, which means that if you create an object within either component, and then lose track of that object, it will eventually be cleaned up.

For example:

function makeABigObject() {
var bigArray = new Array(20000);
}

When you call that function, the JScript component creates an object (named bigArray) that is accessible within the function. As soon as the function returns, though, you "lose track" of bigArray because there's no way to refer to it anymore. Well, the JScript component realizes that you've lost track of it, and so bigArray is cleaned up--its memory is reclaimed. The same sort of thing works in the DOM component. If you say document.createElement('div'), or something similar, then the DOM component creates an object for you. Once you lose track of that object somehow, the DOM component will clean up the related.

If you are using the Postgres Mac app (by Heroku) and Bundler, you can add the pg_config directly inside the app, to your bundle.

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

...then run bundle again.

Note: check the version first using the following.

ls /Applications/Postgres.app/Contents/Versions/

Here is an awesome and precise explanation I found.

TIMESTAMP used to track changes of records, and update every time when the record is changed. DATETIME used to store specific and static value which is not affected by any changes in records.

TIMESTAMP also affected by different TIME ZONE related setting. DATETIME is constant.

TIMESTAMP internally converted a current time zone to UTC for storage, and during retrieval convert the back to the current time zone. DATETIME can not do this.

TIMESTAMP is 4 bytes and DATETIME is 8 bytes.

TIMESTAMP supported range: ‘1970-01-01 00:00:01' UTC to ‘2038-01-19 03:14:07' UTC DATETIME supported range: ‘1000-01-01 00:00:00' to ‘9999-12-31 23:59:59'

Recent Clang compiler has a __FILE_NAME__ macro (see here).

Parcelable much faster than serializable with Binder, because serializable use reflection and cause many GC. Parcelable is design to optimize to pass object.

Emulator:

Consider a situation that you know only English and you are in China. In order to interact with a Chinese person you need a translator. Now, role of translator is that it will seek input from you in English and convert to Chinese and and give that input to the Chinese person and gets response from the Chinese person and convert to English and give the output to you in English. Now that translator and Chinese person is the emulator. Both combine will provide similar functionality as if you were communicating with the English person. So hardware may be different but functionality will be same.

Simulator:

I can't give better example than SPICE or flight simulator. Both will replace hardware component behavior with the software or mathematical model which will behave similar to the hardware.

In the end it depends on the context that which solution better suits project needs.

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

The easiest solution is to just run your own counter thus:

int i = 0;
for (String s : stringArray) {
    doSomethingWith(s, i);
    i++;
}

The reason for this is because there's no actual guarantee that items in a collection (which that variant of for iterates over) even have an index, or even have a defined order (some collections may change the order when you add or remove elements).

See for example, the following code:

import java.util.*;

public class TestApp {
  public static void AddAndDump(AbstractSet<String> set, String str) {
    System.out.println("Adding [" + str + "]");
    set.add(str);
    int i = 0;
    for(String s : set) {
        System.out.println("   " + i + ": " + s);
        i++;
    }
  }

  public static void main(String[] args) {
    AbstractSet<String> coll = new HashSet<String>();
    AddAndDump(coll, "Hello");
    AddAndDump(coll, "My");
    AddAndDump(coll, "Name");
    AddAndDump(coll, "Is");
    AddAndDump(coll, "Pax");
  }
}

When you run that, you can see something like:

Adding [Hello]
   0: Hello
Adding [My]
   0: Hello
   1: My
Adding [Name]
   0: Hello
   1: My
   2: Name
Adding [Is]
   0: Hello
   1: Is
   2: My
   3: Name
Adding [Pax]
   0: Hello
   1: Pax
   2: Is
   3: My
   4: Name

indicating that, rightly so, order is not considered a salient feature of a set.

There are other ways to do it without a manual counter but it's a fair bit of work for dubious benefit.

Surely you want to know about window.requestIdleCallback(), which queues a function to be called during a browser's idle periods.

You can see an elegant usage of this API in the Quicklink repo.

const requestIdleCallback = window.requestIdleCallback ||
  function (cb) {
    const start = Date.now();
    return setTimeout(function () {
      cb({
        didTimeout: false,
        timeRemaining: function () {
          return Math.max(0, 50 - (Date.now() - start));
        },
      });
    }, 1);
  };

The meaning of the code above is: if the browser supports requestIdleCallback (check the compatibility), uses it. If is not supported, uses a setTimeout(()=> {}, 1) as fallback, which should queue the function to be called at the end of the event loop.

Then you can use it like this:

requestIdleCallback(() => {...}, {
    timeout: 2000
  });

The second parameter is optional, you might want to set a timeout if you want to make sure the function is executed.

First letter of file name and class name must be in Uppercase.

Your model class will be

class Logon_model extends CI_Model

and the file name will be Logon_model.php

Access it from your contoller like

$this->load->model('Logon_model');

You need to use data: {title: title} to POST it correctly.

In the PHP code you need to echo the value instead of returning it.

I find the easiest way to use timeit is from the command line:

Given test.py:

def InsertionSort(): ...
def TimSort(): ...

run timeit like this:

% python -mtimeit -s'import test' 'test.InsertionSort()'
% python -mtimeit -s'import test' 'test.TimSort()'

HTH!

You can use Len(StrFile) > 0 in loop check statement !

Sub openMyfile()

    Dim Source As String
    Dim StrFile As String

    'do not forget last backslash in source directory.
    Source = "E:\Planning\03\"
    StrFile = Dir(Source)

    Do While Len(StrFile) > 0                        
        Workbooks.Open Filename:=Source & StrFile
        StrFile = Dir()
    Loop
End Sub

Your code works, but the fadeIn doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut → load → fadeIn:

var auto_refresh = setInterval(function () {
    $('.View').fadeOut('slow', function() {
        $(this).load('/echo/json/', function() {
            $(this).fadeIn('slow');
        });
    });
}, 15000); // refresh every 15000 milliseconds

Try it here: http://jsfiddle.net/kelunik/3qfNn/1/

Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax and $.ajaxSetup ({ cache: false }); or the random-hack, he mentioned.

If you want to align center on left attribute.
The same thing is for top alignment, you could use margin-top: (width/2 of your div), the concept is the same of left attribute.
It's important to set header element to position:relative.
try this:

#logo {
    background:red;
    height:50px;
    position:absolute;
    width:50px;
    left:50%;
    margin-left:-25px;
}

DEMO

If you would like to not use calculations you can do this:

#logo {
  background:red;
  width:50px;
  height:50px;
  position:absolute;
  left: 0;
  right: 0;
  margin: 0 auto;
}

For new MySQL 5.6 family you need to install php5-mysqlnd, not php5-mysql.

Remove this version of the mysql driver

sudo apt-get remove php5-mysql

And install this instead

sudo apt-get install php5-mysqlnd

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

Non-recursively List Only Directories

The only question that direct asked this has been erroneously closed, so I have to put it here.

It also gives the ability to filter directories.

In Javascript the idea of boolean is fairly ambiguous. Consider this:

 var bool = 0 
 if(bool){..} //evaluates to false

 if(//uninitialized var) //evaluates to false

So when you're using an if statement, (or any other control statement), one does not have to use a "boolean" type var. Therefore, in my opinion, the "=== true" part of your statement is unnecessary if you know it is a boolean, but absolutely necessary if your value is an ambiguous "truthy" var. More on booleans in javscript can be found here.

You should find installed packages in :

anaconda's directory / lib / site_packages

That's where i found mine.

If you are using ajax, you may want to get updated value of select right after the selection.

//Part 1

$(".element").select2(/*Your code*/)    

//Part 2 - continued 

$(".element").on("select2:select", function (e) { 
  var select_val = $(e.currentTarget).val();
  console.log(select_val)
});

Swift 4.2 and Xcode 10. Somewhere in ViewController:

private lazy var debugInfoLabel: UILabel = {
    let label = UILabel()
    label.textColor = .white
    label.translatesAutoresizingMaskIntoConstraints = false
    yourView.addSubview(label)
    NSLayoutConstraint.activate([
        label.centerXAnchor.constraint(equalTo: suggestionView.centerXAnchor),
        label.centerYAnchor.constraint(equalTo: suggestionView.centerYAnchor, constant: -100),
        label.widthAnchor.constraint(equalToConstant: 120),
        label.heightAnchor.constraint(equalToConstant: 50)])
    return label
}()

...

Using:

debugInfoLabel.text = debugInfo

I put the code together from the accepted answer in a generic extension method, so it could be used for all kinds of objects:

public static string DescriptionAttr<T>(this T source)
{
    FieldInfo fi = source.GetType().GetField(source.ToString());

    DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(
        typeof(DescriptionAttribute), false);

    if (attributes != null && attributes.Length > 0) return attributes[0].Description;
    else return source.ToString();
}

Using an enum like in the original post, or any other class whose property is decorated with the Description attribute, the code can be consumed like this:

string enumDesc = MyEnum.HereIsAnother.DescriptionAttr();
string classDesc = myInstance.SomeProperty.DescriptionAttr();

Another options is to use the open source tool NuGet Package Explorer for this.

From a Nuget package (.nupkg) you could check the PublicKeyToken, or drag the binary (.dll) in the tool. For the latter select first "File -> new"

If you are already restricted/hardcoded your algorithm to using a std::vector::iterator and std::vector::iterator only, it doesn't really matter which method you will end up using. Your algorithm is already concretized beyond the point where choosing one of the other can make any difference. They both do exactly the same thing. It is just a matter of personal preference. I would personally use explicit subtraction.

If, on the other hand, you want to retain a higher degree of generality in your algorithm, namely, to allow the possibility that some day in the future it might be applied to some other iterator type, then the best method depends on your intent. It depends on how restrictive you want to be with regard to the iterator type that can be used here.

• If you use the explicit subtraction, your algorithm will be restricted to a rather narrow class of iterators: random-access iterators. (This is what you get now from std::vector)

• If you use distance, your algorithm will support a much wider class of iterators: input iterators.

Of course, calculating distance for non-random-access iterators is in general case an inefficient operation (while, again, for random-access ones it is as efficient as subtraction). It is up to you to decide whether your algorithm makes sense for non-random-access iterators, efficiency-wise. It the resultant loss in efficiency is devastating to the point of making your algorithm completely useless, then you should better stick to subtraction, thus prohibiting the inefficient uses and forcing the user to seek alternative solutions for other iterator types. If the efficiency with non-random-access iterators is still in usable range, then you should use distance and document the fact that the algorithm works better with random-access iterators.

I am using Spring Boot with Thymeleaf. This is what worked for me. There are similar answers with JSP but note that I am using HTML, not JSP, and these are in the folder src/main/resources/templates like in a standard Spring Boot project as explained here. This could also be your case.

@InjectMocks
private MyController myController;

@Before
public void setup()
{
    MockitoAnnotations.initMocks(this);

    this.mockMvc = MockMvcBuilders.standaloneSetup(myController)
                    .setViewResolvers(viewResolver())
                    .build();
}

private ViewResolver viewResolver()
{
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();

    viewResolver.setPrefix("classpath:templates/");
    viewResolver.setSuffix(".html");

    return viewResolver;
}

Hope this helps.

when you add a new data set to a geom you need to use the data= argument. Or put the arguments in the proper order mapping=..., data=.... Take a look at the arguments for ?geom_line.

Thus:

p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red") 

Or:

p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red")

If you want the script to run in the current shell (e.g. you want it to be able to affect your directory or environment) you should say:

. /path/to/script.sh

or

source /path/to/script.sh

Note that /path/to/script.sh can be relative, for instance . bin/script.sh runs the script.sh in the bin directory under the current directory.

implements means a behaviour will be defined for abstract methods (except for abstract classes obviously), you define the implementation.

extends means that a behaviour is inherited.

With interfaces it is possible to say that one interface should have that the same behaviour as another, there is not even an actual implementation. That's why it makes more sense for an interface to extends another interface instead of implementing it.

On a side note, remember that even if an abstract class can define abstract methods (the sane way an interface does), it is still a class and still has to be inherited (extended) and not implemented.

Actually most of the answers here doesn't really scale the image to the width of itself.

We need to have a width and height of auto on the img element itself so we can start with it's original size.

After that a container element can scale the image for us.

Simple HTML example:

<div style="position: relative;">
    <figure>
       <img src="[email protected]" />
    </figure>
</div>

And here are the CSS rules. I use an absolute container in this case:

figure {
    position: absolute;
    left: 0;
    top: 0;
    -webkit-transform: scale(0.5); 
    -moz-transform: scale(0.5);
    -ms-transform: scale(0.5); 
    -o-transform: scale(0.5);
    transform: scale(0.5);
    transform-origin: left;
} 

figure img {
    width: auto;
    height: auto;
}

You could tweak the image positioning with rules like transform: translate(0%, -50%);.

PHP uses weak typing (which it calls 'type juggling'), which is a bad idea (though that's a conversation for another time). When you try to use a variable in a context that requires a boolean, it will convert whatever your variable is into a boolean, according to some mostly arbitrary rules available here: http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting

Just add a >NUL at the end of the lines producing the messages.

For example,

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >NUL

Use this:

var memoryStream = new MemoryStream();
stream.CopyTo(memoryStream);

This will convert Stream to MemoryStream.

For those people using Python, you may consider using Selenium Wire, which can set request headers, as well as provide you with the ability to inspect requests and responses.

from seleniumwire import webdriver  # Import from seleniumwire

# Create a new instance of the Firefox driver (or Chrome)
driver = webdriver.Firefox()

# Create a request interceptor
def interceptor(request):
    del request.headers['Referer']  # Delete the header first
    request.headers['Referer'] = 'some_referer'

# Set the interceptor on the driver
driver.request_interceptor = interceptor

# All requests will now use 'some_referer' for the referer
driver.get('https://mysite')
