Getting RPC_E_SYS_CALL_FAILED in IDispatchEx::GetDispID() for an out-of-proc IDispatch pointer

SP42086 asked:

Hi there,
I’m trying to add few automation objects to the scripts (hosted via a separate process (ATL EXE server)). Also I am trying to sink the events from these automation objects inside my ATL EXE script engine.
To achive this I’m using CDispExSinkConnector as described in http://www.codeproject.com/Articles/3326/Extending-the-Internet-Explorer-Scripting-Engine
As described I’m using IDispatchEx::GetDispID()to create new members inside the scripting engine. Once the member DISPID has been created, I’m using InvokeEx()to set the property value.
But these method calls return RPC_E_SYS_CALL_FAILED.
Note- Here I get the IDispEx pointer from an OUT-OF-PROC IDispatch pointer.
Any quick guidance/ help will be much appreciated.
Thanks,
SP
