close terminal window

Hi,

I make a program wich open the terminal window(C:\WINDOWS\system32\cmd.exe) at each time it's fired. I use it in a loop, so I got many useless terminal windows.

My question is : how to close a terminal window from matlab.

Greetings, Steven

Hi Steven,

"I make a program" needs some guessing about what you are doing. Perhaps you could describe this in more detail?

Titus

[Steven]

I rather mean, I call a program wich opens a terminal windows, make some calculus, but when it's finished, the terminal doesn't close

[Steven]

The point is not with the program itself, for example, just launch the cmd.exe from windows start-up menu, then how could you close it from matlab ?

[Dr. Seis]

I have a program that launches some xterm windows (on my Unix machine) to run other non-Matlab things in the background. Once they finish their job, the xterm automatically closes. Are you looking for a similar behavior, but with an MS-DOS command prompt?

[Steven]

It might be usefull, but I'm more looking for something simpler : I dont want to run anything in the background, I just want to close a windows.

[Titus Edelhofer]

Hi Steven,

O.K., I see. How do you call the other program (system? Using "!"?)

Titus

[Steven]

I know it uses java socket, but I can't tell you really more for now, but go ahead with some ideas using system, I'm interested.

Answer 1

[Steven]

I got it, I thought matlab could do it by itself, but instead I modify the batch file of the program.

Assume you run your MATLAB code as system('MyProgram.exe') and it brought up that ugly black window but never exits, you can do this:

system('MyProgram.exe < Exit.txt'), where Exit.txt is a text file you created ahead of time. The text file contains one line, which is 'exit' without both the single quotes.

[Steven]

It doesn't work, I got the following :

Microsoft Windows XP [version 5.1.2600]

(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\DA2191\Bureau\complexe_calib_MLEp\old>Plusÿ?

ans =

0

It like if I must add something to confirm (y/n) ?

[Fangjun Jiang]

So, you are using system(), right? Maybe I should emphasize that the text file should contain the text "exit" and then a carriage return. As if you are doing it manually. In one of the open command window, if you type exit and then return, it will close the window, right?

Answer 3

[Steven]

Yes, if I type exit in the terminal, it close the windows.

[Steven]

My text file is Exit.txt, it contains only : exit

[Fangjun Jiang]

Then add that carriage return in the text file after the exit, and save the file. It should work.

[Steven]

In my text file, when I add "return" at the second line, I got :

Microsoft Windows XP [version 5.1.2600]

(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\DA2191\Bureau\complexe_calib_MLEp\old>exit

But the terminal is not closed. If my text file is "exit return", well I got the samething as before.

[Fangjun Jiang]

Not the literal text "return". I mean the carriage return, the "Enter" key stroke!

[Steven]

Ok I see, well It doesn't work, I got as usual:

Microsoft Windows XP [version 5.1.2600]

(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\DA2191\Bureau\complexe_calib_MLEp\old>exit

ans =

0

[Fangjun Jiang]

I don't understand. You still have not answered the question how your program brought up the Cmd window. See this post yourself.

[Fangjun Jiang]

It should be the less than sign "<", not the greater than sign ">"!!!

Perhaps not so elegant, but if you incorporate the following it works just fine:

keyInject('C:\Windows\system32\cmd.exe','exit','C:\Windows\system32\cmd.exe');

keyInject('C:\Windows\system32\cmd.exe','\r','C:\Windows\system32\cmd.exe');
