Re: Creating event objects

Thank you very much, Vitaly,

Hmmm, about 3000 times...get type info...

I'll be in touch and let you know how it goes.

>I can give you an idea of custon interface (not Dispatchable) Event handling. Get COMDelegator OpenSource. There you will find code for intercepting function calls on VTLB. So create such class object wrapper with only one function, which is cloned to this VTLB about 3000 times. This function should have two parameters: Method Number and Argument Array. While init. this wrapper should get TypeInfo for this Event Interface. The rest you will find in COMDelegator OpenSource.
