Python Keypress in Nostale

Hi,
I wasn't able to simulate key press and key inputs in nostale using python, can anyone guide me in how to use a python script to simulate a key press in nostale? is it because of directx?

You can send keys to a window with PostMessage function:
[Only registered and activated users can see links. Click Here To Register...]

For key codes:
[Only registered and activated users can see links. Click Here To Register...]

If you already know this and still not work make sure you are running your program as an administrator

Thanks Hatz, it wasn't working because I wasn't running the script as admin, silly mistake >_<
