Hi Andy,
Thanks for your reply.
Yes, I rebuilt the Crypto++ LIB and my wrapper DLL under VS2008. When
it wasn't working as expected, I built 5.5.2 under VS2003 and re-tried
with the original code and noticed the exception.
You are right - I once tried to call the VS2003 version of my wrapper
DLL from VS2008 and really nasty things happened.
