Issue Details

I need to programmatically determine which window is active on my computer using LabVIEW. 


Call GetForegroundWindow function from Windows' user32.dll using the Call Library Function node on your block diagram to return the handle of the active window. You can also call the GetWindowText function to return the name of the active window.
