How do you execute the bat file? Do you use RUN?

By default this should stop processing until the bat has run its course.

If you use ShellExecute you can use the window handle that is passed back in the structure and check the window existence with the IsWindow api.

Alternatively, you might want to look in the downloads section for Ed Rauh's Launch App or something like this. He has already has written code to launch external utilities and has parameters to wait etc.
