Hi, I am getting an InvalidCastException when I am calling a COM object RTCClient from ASP.NET. Below is the exception: Unable to cast COM object of type 'RTCCore.RTCClientClass' to interface type 'RTCCore.IRTCClient'. This operation failed because the QueryInterface call on the COM component for the interface. I got know the work arround for this is: "In your C#/VB.NET code you need to use the Activation Context APIs before you create your RTCClient object. You will need to use PInvoke to reference these APIs from your code. The main ones you need are: CreateActCtx ActivateActCtx DeactivateActCtx" But I am not sure of creating CreateActCtx and play with it. It would be great if some one can help me in doing this. Thanks in Advance:
