Error message strategy for a C++/ATL COM server

I have developed a C++/ATL COM server application that needs a better error return strategy than I'm using at the moment. Basically I have lots of possible errors that need returning as codes and optional string descriptions. I've had a look around and it looks like I need to use MAKE_HRESULT(SEVERITY_ERROR, FACILITY_ITF, code_200_hex_and_above) to define my codes and then join them up with the message strings in some kind of table.  Then I can use an HRESULT and Error("Message goes here") to pass the code and description over. Can someone please show me a nice way of implementing this (should I be using the resource compiler?)

I just built my own error handling in the end.
