Thanks Siddaharth,

My COM DLL is already in use by VB and .NET clients. The problem I am facing is actually that the new methods that I have add to the COM DLL are not exposed to VB/.NET clients (probably not exposed to any body).

My IDL interface defination confirms to what you have suggested:
Code:
  interface IMyComClass : IDispatch
  {
  }
Even after updating .IDL, .CPP and .H file for new methods, my new methods are still not exposed.

Regards,
