Wait, spoke a bit too soon. I noticed that you (Tim) apparently missed a zero in your first method of building the bits (8 with 6 zeros instead of 7), which generates only a 28bit number, not 32bits. (which i blindly copy pasted at first...). when i try to make an actual 32bit value, and then send it to the PostMessage function, i get the following exception:
win32api.PostMessage(self.subHwnd, win32con.WM_KEYDOWN, virtualKeyCode, keyDownBits) OverflowError: long int too large to convert to int as i understand it, then... PostMessage expects exactly 32bits... and my guess is that since python has no unsigned ints, a 32bit value needs more than 32bits, so python makes it a long, and then postmessage complains about longs because it expects an int-sized value. Would that be a bug in python's implementation of PostMessage, or am i missing something? btw, postmessage(keydown) works just as well with a 31-bit value... so i guess i have no problem with this, just asking out of curiosity.
