CapeErrorInterfaceHR Enumeration

Extracted from "Strategies for Handling Errors in COM+", in Platform SDK help

Use the FACILITY_ITF range of errors to report interface-specific errors.

Interface-specific errors should be in the FACILITY_ITF range of errors,between 0x0200 and 0xFFFF. However, since Microsoft uses some codes after 0x0200, the CAPE-OPEN error codes will start at 0x0500

Use the MAKE_HRESULT macro in C++ to introduce an interface-specific error code, as shown in the following example:

const HRESULT ERROR_NUMBER = MAKE_HRESULT (SEVERITY_ERROR, FACILITY_ITF,10);

So, offset on FIRST_E_INTERFACE_HR must be between 1 and 64255 (0xFFFF-0x0500). We reserve the 0 offset.

const int FIRST_E_INTERFACE_HR = (int)0x80040500;

last HR value used for a CO error interface const int LAST_USED_E_INTERFACE_HR = (int)0x80040517;

highest HR value that could be used to represent a CO error interface const int LAST_E_INTERFACE_HR = (int)0x8004FFFF;
