COM/DCOM Exception Class

This article includes an updated SYSEX exception class. I would like to thank Dale Nagata for testing out the earlier version with an in-process server (something I had not done) and for pointing some nasty problems. The updated version includes fixes to these as well as some other enhancements.

The updated version now propagates error line number and file occurences in the source window as demonstrated above. It also includes some additional macros which you may or may not find useful. One of the issues pointed out by Dale was the inability of the previous version to display the correct module name in the source window when using an in-process server. The fix I decided on was to include an external global variable initialized as follows HINSTANCE g_hMODInstance=NULL which you can set in DLLMain.

#include "sysex.h"

                    DWORD dwReason, 
                    LPVOID /* lpReserved */)
 if (dwReason == DLL_PROCESS_ATTACH)
  _Module.Init(ObjectMap, hInstance, &LIBID_SYSEXSERVERLib);
 else if (dwReason == DLL_PROCESS_DETACH)
 return TRUE;    // ok

I apologize for the delay in getting the fixes done. Please feel free to modify the code if you see fit.
