write string to running program

Hello Experts!!

I have a simple question;

I make use of a Windows-DOS program, and needs to send a string to that program, like "add user brian". How can I do that? I work in VB5_pro.

I expect that I have to make use of SENDKEYS, but how do I call the right program. Not shell - since I do not want to execute the program, it is already running.

Can some one help with this question?

Thank you!

Do you have access to the code of the program you wish to receive the message (the Windows/DOS one)?  If so, you could have it constantly reading a file that another one writes commands to.  Or look into DCOM.

If you do not have access to the code, you may not be able to send a message to the other program.  How does the other program work?  Command line arguments?  Can't you stop that program and reload it?
SendKeys can't send text to a DOS window, but there is a work-around that usually works just fine.
(Note: DOS app may need to be running in a window instead of full-screen for this to work)


Appactivate Caption_Of_Window_To_Activate, True
ClipBoard.SetText Text_To_Send, vbCFText
SendKeys "% ", True
SendKeys "ep", True

Hope this helps!

Well I could not get it working, tried a little, but then found out another way. Seems there is a commandline thing included with my server that this was for ~:\

Anyway I grade KDivad. But thanks to you all experts!
