Hi Ray, I kind of found the problem. The import should be:
from ctypes import *
Now I am getting a message box but the characters in it are garbage. I
was tried to send an image but apparently this list does not allow that.
Here is my trivial test program:
#!/usr/bin/python
from ctypes import *
user32=cdll.LoadLibrary('/cygdrive/c/Windows/System32/User32.dll')
mbw=getattr(user32,"MessageBoxW")
mbw(0,'Hello world!!','Hello',2)
