ActiveX controls implementation differences in VB6 & python using win32com. -
i have third party activex controls designed used in vb6. want migrate controls python. got win32com , ran 'makepy.py -i' on type library file. understand how dispatch executable container using win32com.client.dispatch() method , call subclasses. container called sterling , running when calls object made, don't exclusively mention container in vb code, figure it's not needed here either. have comm objects type library, however, seems work in vb6. vb6 code works , accesses com object after add reference sterling.tlb type library:
' declare activex type library class public withevents m_stiquote stiquote private sub form_load() ...................................... ' create instance of type library class set m_stiquote = new stiquote ...................................... end sub private sub form_unload(cancel integer) ......................................
