Using calldll with mciSendString

[Nikolai Kirsebom]

I'm trying to use the windll/calldll module to access the mciSendString
(winmm.dll) function.  One of the parameters to the function is a string
containing returned information.  I'm using wxPython as GUI to show a AVI /
MPEG movie (in a wxPanel).  The play command may be given a 'notify' flag,
which results in the player calling back to notify when movie is finished.
The last parameter to the mciSendString is a HANDLE (hwndCallback).

Can someone give an example how to retreive the returned information and
also how I set up the callback.


Thanks
