C# COM visible Control (*.tlb) Events Needed?

Question

Hi I have a huge problem. I've created a COM control in c# which I wish to use in VB6. Everything is working perfectly except events.

I've created an event which I can see in my c# test harness but when I go to use the control in VB6 I see two strange methods have appeared (add_EventHandlerNameHere and remove_EventHandlerNameHere)
These both take in one parameter "value as unknown".

I can't figure out how to use these methods or how to see the event properly from with VB6. Any help would be really appreciated as I'm on a really tight schedule for this.

Many Thanks,
Kiran

No solution, but a little background information. Every COM interface must implement IUnknown. I guess that is why you see value as unknown. The method add_EventHandlerNameHere expects an instance of an class that implements IUnknown.

The methods probably do the same job the operators += and -= do in c#.
Try using it thinking like this.

Most likely reason is you are not implementing IDispatch. Is that so?
