How to programmatically switch active windows in LabView

I am currently executing a third party software using the System Exec.vi from LabView. I need to send some keyboard input to this program, but it can't be through the standard input, but rather like Windows (i.e. if you click Alt+F4 the window closes, Alt+F goes to the File Menu, etc.). I already have a way of inserting this keyboard combinations into the program, but the problem I'm having is that as soon as I execute it with the System Exec, this program goes somehow to the background. This happens even when I have "run minimized" set to false, and regardless of the state of "wait until completion".

Since I can't figure out what is making the program window go to the background, what I need is to switch from the LabView window (which always remains active) to the program one. Does anyone know a way of doing this?

Thanks!

If you know the Name of the Window you'd like to activate, you could use FindWindowA and SetForegroundWindow of the Windows API user32.dll via "Call Library Function".
