hi I am trying to get PID from the foreground window, but this doesn't work because I am passing the wrong kind of handle to the function. This is under python.

How do I fix this?
thx!


Code: 
import ctypes
import time

time.sleep(2)
handle = ctypes.windll.user32.GetForegroundWindow()
print(handle)
PID = ctypes.windll.kernel32.GetProcessId(handle)
print (PID)
 
Solution
GetWindowThreadProcessId can be used to get the PID directly without the need for GetProcessId.

Well the handle being returned from GetForegroundWindow is actually a handle to the Window and not the parent process. You can get the Thread process Id of the Window with ctypes.windll.user32.GetWindowThreadProcessId(handle) and from there you may be able to get the spawning process handle and then call GetProcessId on that handle.
