There are two exception codes that can be raised when failures are encountered:
Here is the exception information:
//
// Exception information
//
#define FACILITY_VISUALCPP ((LONG)0x6d)
#define VcppException(sev,err) ((sev) | (FACILITY_VISUALCPP<<16) | err)
The exception codes thrown are the standard VcppException(ERROR_SEVERITY_ERROR, ERROR_MOD_NOT_FOUND) and VcppException(ERROR_SEVERITY_ERROR, ERROR_PROC_NOT_FOUND) values. The exception passes a pointer to a DelayLoadInfo structure in the LPDWORD value that can be retrieved by GetExceptionInformation in the EXCEPTION_RECORD structure, ExceptionInformation[0] field. See to Structure and Constant Definitions for more information.
