I doubt it -- that would be the mistake of a C/C++ beginner.

Duh.  Fernando's original problem was that the compiler couldn't find the
function prototype.  By including mapix.h and getting the error I did, I
showed that the prototype for MAPILogonEx is found and recognized by the
compiler.  No need to use LoadLibrary or GetProcAddress.  I'm leaving it up
to Fernando to figure out how to pass the correct arguments.

The point is, mapi.hpp (which is a Borland header file) does not include it,
even though one might think it should.
