Re: Prioprietary DLL link problem - Can't export...

[Robert Bercik <robertjbercik at yahoo dot com>]

Hi guys,

     I'm still trying to figure out how to fix this.
I've been scouring the internet looking for anyone
who's had a similar problem and someone mentioned
creating a definition file. Do I need to pass a .def
file to the linker. I really could use some help,
thanks guys...
