I am writing a COM client prog in MFC / Visual studio 2003. The COM server has an event (callback) interface and a "normal" interface. I have created the class for the "normal" interface thru the class wizard Add Class from the TLB file of the server object. I use this class thru ::CreateDispatch. For the callback interface, I have found that the wizard Add Claas does not create something I could use, so I have created by hand a class, derived from CCmdTarget with automation capabilities. Now the question : How do I use the class wizard to create in that class (with the correct DISPATCH TABLE entries) the callback functions I want to implement from my object ? And how do I instanciate that class ? Thanks for helping me. Franois.

The article is good on COM evnets, but I am really seeking for is as the article says how can I fit an event handler into my code via the wizard. There are some ms KB explaining how to do it by hand (DISP_FUNCTION_IDand so), but I am trying to do it with the wizard.
