Re: how to use activex in wxpython with event support

i have solve the problem.my solution is :since this activex(DICOM)
works fine in vb,and i know activex controls developed by vb works
fine in python,so why cant i develop an activex control which wrap
this activex(DICOM)? so i build a vb's activex project insert this
activex(DICOM) in it and delegate this control(DICOM) events into vb
control's event.

this activex developed by vb works fine in wxpython,MakeAc tiveXClass
works fine.

but i really dont understand why this method works,can you give me
some explanation?

best regards.
