Remarks

The GetVersion method returns nonzero results only if the writer was initialized by calling the CVssWriterEx::InitializeEx method and explicit version information was specified. If the writer is initialized by calling the CVssWriter::Initialize method, or if no version information was specified in the call to the CVssWriterEx::InitializeEx method, the GetVersion method returns zero in the pdwMajorVersion and pdwMinorVersion parameters.
