Get IMAPI2 error string
Ah hello.
I would like to know if there is any method, apart from a huge self-written switch statement, to obtain the descriptive string associated with an IMAPI2 error. For example
E_IMAPI_RECORDER_MEDIA_NO_
I thought that
_com_error_(<erroneous HRESULT>).ErrorMessage()
would do the trick, but it always comes back with "Unknown error".
Any ideas?
TIA

Thanks for the response. Unfortunately that does not work. I used
HRESULT_CODE(hResult)
to extract the integer error code then passed this along to FormatMessage. The integer error code is 514, which does not correspond to an error message using the tool ErrLookup. Sure enough, FormatMessage brings back an empty string.

Look into the Microsoft macros that are specifically intended for handling HRESULT values (your hex error code is an HRESULT).

Regarding the original question, use the Win32 WPI FormatMessage to get the system error message.
