The CCOW Context Management Architecture defines a set of exceptions that components can raise. There is no provision in the current standard for context participant applications to throw exceptions.
All automation and dual interface methods in ActiveX implementation return 32-bit encoded HRESULT error values. In addition, the Microsoft-defined IErrorInfo and ISupportErrorInfo interfaces can provide additional error information including a textual description of the error and the GUID of the interface that threw the error.
The of CCOW Context Management Architecture defined HRESULTS values are listed in the table below:
