Event handling (C# vs VB6.0)

If you have it wrapped properly, you are most of the way there. In the
object declaration, add with Events (Dim with Events objectName as
TypeofWrapper). It is then a matter of matching the interface. You should
see the events on the COM wrapper and be able to bind to them.

I have the following code in C# to "sink" an event with an event
handler.

Obj.OnCallEvent +=new CallEventHandler(obj_OnCallEvent);

obj_OnCallEvent being the actual method and "obj.OnCallEvent" is the
actual event.

This events are provided by a 3rd party Dll.

I have converted that dll into a type library and used it in VB6.0

However, I'm not sure how to "sink" events in VB6.0!

Please advise what would be a compatible statement in VB6.0 for above
C# code?

You'll need to have a class or form level variable declare WithEvents
(e.g. Dim WithEvents Obj as TargetObject). You'll then be able to write
a function called Obj_OnCallEvent (or similar) which handles the event.
This is assuming that the event is one that VB can hook up to - e.g.
that it is declared in a COM interface as an event (IIRC).
