Adding a new Interface to Existing component

[BicycleTheif]

Hi i have added a new interface to an existing component.but when i tried to access the interface in the client program it is saying "access to QueryInterface failed". In this i have two interface both are derived from IDispatch. In COM_INTERFACE_ENTRY i have a ambigiuty error..i solved it with COM_INTERFACE_ENTRY2 macro. Is this have any effect onthe previous error.. Thanks in Advance

Which interface showed error. first one or second one? and how did u call. thru IDispatch or queryinterface? COM_INTERFACE_ENTRY2 has impact on the calling mechanism, if u have more than IDispatch interfaces in a single CoClass. U can't invoke the second interface bu using IDspatch Invoke mthd. You have to use QueryInterface for that . Only the first Interface can have IDispatch Invokation. rgds...mil10
