I have been pining over implementing what seems to be a VB custom com interface for some time now, so I thought I would post to the list to see if anyone could help.
I have a com component on which I have run makepy. The function generates a couple of classes with functions and callbacks that all work fine when I DispatchWithEvents. However there is one interface that I cannot figure out how to use. This interface is only referenced in the vtables section as foo_vtables_dispatch_ = 0 foo_vtables_ = [ (( 'OnFunc1' , 'variable1' , ), 1610678272, (1610678272, (), [ (36, 1, None, None) , ], 1 , 1 , 4 , 0 , 12 , (3, 0, None, None) , 0 , )), (( 'OnFunc2' , 'variable2' , ), 1610678273, (1610678273, (), [ (36, 1, None, None) , ], 1 , 1 , 4 , 0 , 16 , (3, 0, None, None) , 0 , )), ] foo is also listed in the VTablesToClassMap and the NamesToIIDMap Now, OnFunc1 and OnFunc2 are callback functions of an interface that I need to implement. Once I implement the interface, I need to pass that object to another com object that will fire callbacks. So reading some of these lists, I thought I should register the interface, create a server, wrap the server and pass it to the other com function. For example: universal.RegisterInterfaces(CLSID,0,2,0,["foo"]) class F: _com_interfaces_=["foo"] _typelib_guid_ = CLSID _typelib_version_ = 2,0 _public_methods_ = [] or ['OnFunc1', 'OnFunc2'] -- i've tried both def OnFunc1: do some stuff def OnFunc2 do some other stuff o=wrap(F) otherDispatchedComObject.FunctionThatNeedsInterface(o, otherInputs) This does not produce any errors, but callbacks to OnFunc1 and OnFunc2 never fire-- and I know they are firing. Also wrapping with a debugging dispatcher adds produces no information. Callbacks to the regularly dispatched com objects do fire. So my question is: Is what I am trying to do possible using win32com? Does this seem like it should work? If not, does anyone have any suggestions using comtypes? I have read that vtable interfaces should be no problem for comtypes, but I can't find much in the way of documentation/examples. Basically, I'm lost here, to the point where I may have to switch to VB (eek)--so any help would be appreciated.
