When I am running batch file through LabVIEW by using System Exec.vi, two cmd windows are appearing. The second one executes command of the batch file and closes after that, while the first one doesn't close. I have tried to use this solution, but it doesn't work. Is there any way to close that first cmd ?
P.S. If I run batch file not through LabVIEW, but just by double clicking on it, two cmd windows close after execution
It's hard to tell, but I think you've misunderstood the directions given at that link. The batch file should contain the executable and its options, but you just pass the batch file to the System Exec VI. I'm guessing what's happening here is the batch file is getting called twice, and some process that the first call depends on is getting hijacked by the second call, so that when the process ends, the second call gets notified and stops itself, but the first call is left hanging. Or something like that.

I'm trying to open a command script, say command1.cmd, from command.cmd, but I want to do this without opening a new console window. I tried start command1.cmd, but it opens a new window. Please can someone tell me how to do this.
Use call or if you're not need to return back to the first script just call the second script directly by its name.
Calls one batch program from another.
CALL [drive:][path]filename [batch-parameters]
batch-parameters Specifies any command-line information required
by the
batch program.
I have a simple VBScript, which executes a batch file in the background. It starts correctly and it's working, but I can't stop it.
I already checked all of these answers, but I have no cscript.exe and no wscript.exe running
Any ideas?
You could try adding an "exit" statement at the end of your batch as long as you don't need to visually see the results (you could just write them to a text file). Just saying, in case you're experiencing this problem in the future.
My programming teacher is requiring that everyone participate in the science fair this year, and now they accept computer-related projects. So, knowing only one language (Windows batch), I asked if I could make some kind of text based game in batch code. She said that I can only write the code, but not execute it.
She said that if we're even caught on the command prompt, we apparently get in big trouble and never get access to a school computer for the rest of the time I'm at the high school, or something like that... Even if all the code contains is a bunch of echos and simple variables, she won't let me and my partner run it. She also said that we must work on the project during school in her class.
So to sum all that up, she's letting me write a game/program, but I'm not allowed to test it to make sure it works in school, which will be when I'm writing it most...
So is there any way to run/test a batch script with simple echo and set /p commands without the "dangerous, black command prompt" showing up?
I think she has no idea what she's talking about, because on the board, she wrote "back script" lol
A batch file runs like any other executable file by double-clicking the file within Windows. However, because a batch file runs in a command line it immediately exits when done, so you may only see a black box for a second.
If the batch file is closing too fast, or you want to read the output from the batch file you can edit the batch file and add a pause to the end of the file. The pause command waits for user input before continuing.
A .BAT file can be made into a .EXE or .COM file to keep the program's source hidden from a user. You could use the .BAT to .EXE converter file to convert the batch files to .EXE file. In this program you can point to the batch file you want to convert into an executable file, include additional files, change the icon of the file, and add file details.
For Information on Batch files, this is one of the best resource.
Try this:
#echo off
color F0
mode con lines=25 cols=60
cls
title "Notepad - MyProgram.bat"
set /P "name=What is your name? "
echo Hello %name%, glad to see you...
pause
Execute it via a double click or enter in files browser...
When i click on a .rb file to run it a CMD window pops up for a brief second and then closes again. This is probably a really nooby question thats easily fixed but i've looked everywhere for help. But like i said it pops up for a brief second and i THINK while its up its executing the code but when the codes done it closes so i don't know if i'm making mistakes in code or other important things like that.
Run the program through the command prompt (CMD), that way you can see the result, otherwise the window closes when the program exits.
Alternatively, you can prevent the program from exiting by putting some sort of blocking instruction at the end of the script, such that the program waits for user input before exiting.
Press Windows_Key+R and then type CMD. Browse to the location of the file and then type ruby your_ruby_file.rb. The program is running, but Windows automatically closes the window upon completion of the command.
To get Windows to run your *.rb files through Ruby when you click on them in the UI, you have to associate the .rb extension with the ruby.exe executable. Such an association is called a "Windows File Association." Here's a Microsoft Knowledge Base article that'll tell you how to create such a thing.

There is a VB6 application. It can be run with command line parameters to create some report in a text file.
The problem is that when started from a batch file, application returns control immediately, so the following commands start executing. I need these following commands to wait until the VB6 app finishes its work.
How to achieve that?
The Start command has a wait switch which does exactly what you want.
c:\start /w notepad
You could rewrite the VB6 program as a console application.
