Call an external executable through system exec.vi. Problems:

[winterishere8]

I have a executable (Fortran i think). I am using System exec.vi to call it and execute. I write a .bat file to configure the execution. It executes fine, but the executable pops up whenever labview calls it. I want to suppress the executable pop-up. Any suggestions ? Do i need to change this in the .bat file or is there any utility in Labview ? Let me know.

The System Exec has an input called "Run Minimized" which defaults to False. Try making it True!

Yours Sincerely

It is already True. That minimizes the dos window. But there is another window (The fortran executable) which runs even after I turn the "Run Minimized" to true.

Hi!

You will need to edit the .bat file or use the "command.com /C" command to close the executable pop-up. Refer to this KnowledgeBase on how to do this.

Hope this helps!

Thanks for your reply. I guess I've not explained the problem properly. I run like 10 iterations, for each iteration a window pops up, some calculation takes place and it closes. This happens for 10 iterations. What I want to do is suppress that window from appearing to the front end user. I want all processes taken place in the background.
