[python-win32] Creating python com objects

[Alex Denham]

Thanks Tim, the program actually reacts when something is dragged over (much better than before).
However i'm receiving an error everytime.
>>> pythoncom error: Unexpected exception in gateway method 'DragEnter'
<type 'exceptions.AttributeError'>: DragEnterpythoncom error: Unexpected gateway error
 
Also, in the documentation it says:
 
Drop(pDataObj, pt, dwEffect)
Parameters

pDataObj : PyIDataObject * 
 
How do i link the IDataObject to the IDragTarget?
 
Thanks
Alex
