You could think all values with 0x80000000 set is an error. In C++, FAILED() macro is the one you should rely on. #define FAILED(Status) ((HRESULT)(Status)<0)
In C#, you could write the same logic, or call Marshal.ThrowExceptionForHR(), which throws appropriate exception for the value, or simply returns if hr is non-error value. -----Original Message----- From: dotnet discussion [mailto:[EMAIL PROTECTED]] On Behalf Of Erick Thompson Sent: Tuesday, May 21, 2002 10:00 AM To: [EMAIL PROTECTED] Subject: Re: [DOTNET] RCW for IFilter and LoadIFilter Mattias, Thanks for your response.

So if the result is E_FAIL, but the severity is a warning, does that I can continue processing, so should I abort the process, or continue? > Why do you want to OR it? My mistake, I want to AND it. If I am going to continue on a warning, I would assume that I would do if ((hResult & 0x07FFFFFFF )>0) I guess I'm just not sure how to interpret various hresults, and documentation isn't very verbose on this.
