Visual C++ Exception-Handling Instrumentation
By Eugene Gershnik, December 01, 2002
Here's an approach to handling exceptions in Visual C++ 6.0 and .NET. By using just a few lines of code, all the exceptions can be properly reported, regardless of what libraries you use and what C++ exceptions they throw.

Listing 1 A boilerplate _CxxThrowException implementation
#include <windows.h>
const DWORD CPP_EXCEPTION = 0xE06D7363;
const DWORD MS_MAGIC = 0x19930520;
extern "C"
void __stdcall _CxxThrowException(void * pObject,
_s__ThrowInfo const * pObjectInfo)
{
const ULONG_PTR args[] ={ MS_MAGIC,
(ULONG_PTR)pObject,
(ULONG_PTR)pObjectInfo };
RaiseException(CPP_EXCEPTION,
EXCEPTION_NONCONTINUABLE,
sizeof(args)/sizeof(args[0]),
args);
}
