system exec and .bat files

[PaulG.]

I searched for this problem but I can't seem to find the exact solution. I have 4 batch files that I can double-click and they work fine. However, when I try to run these .bat files in LV with the System Exec VI I get "blahblablah file not found" errors. How can I duplicate double-clicking on a .bat file in LV?

Hi PaulG,

how do you call your bat files? Normally it should work with the System Exec vi.

Figured out part of my own problem, but now I have another related one. Now when the bat file completes the window stays open and I have to manually close it. This is not the same behavior as double-clicking the .bat file itself. With a double click I just press any key and the window closes. I guess what I want is a method in LV that exactly duplicates double-clicking a .bat file.

Hi PaulG,

maybe you get the same behavior as a double click if you use the "ShellExecute" function from the shell32.dll.

Hope it helps.

I've done very little with Call Library Function Node. I was hoping for something a little simpler.

Hi PaulG,

see the attached vi please. For me it works as expected.

Hi PaulG.,

I have found this article (KnowledgeBase 18T91CVJ:  After Running a Batch File with the System Exec VI, the Command Window Rema...), which offers a couple of options for forcing the .bat file to close.  I would try adding the "exit" command to your batch file.
