Board index » Visual Studio » CanBeDone: unmanaged IntPtr to Delegate?

Visual Studio281
Hello:

I am trying to write a wrapper for the WabApi (wich manages the Windows

Adress Book).

It uses some "kind of" interfaces, like IWABObject. But these interfaces

dont have Guids, and QueryInterface fails.

So I am thinking of getting the VTable and calling its methods.

I allready have the Vtable wich is something like this:



public structure IWABObjectVtbl

QueryInterface as IntPtr

etc.

...

end structure



The question is How can i cast the IntPtr to a delegate so I can call the

method?



Thanks a lot!!

Alejandro,



That's currently not possible, but will be in Whidbey.



In the meantime, I would suggest handling things like this in a VC++

component.

Thank you for the answer!!!



I have never did any programming in C++ but after spending an hour I dont

find it so difficult (for this kind of small project).
