Try these urls for all you need for PInvoke(platform invoke), one from MSDN and the other with all the functions.  Hope this helps.

hi This is sachin,
I want to know is there any method to use the callback COM interfaces? I am trying to use an unmamaged COM  interface named IDebugEventCallbacks which can be found in "Dbgeng.h" file.

Thanks
Sachin
