Hi, I am trying to use a 32-bit dll to access the parralell port. My problem is that in trying to import the fucntions into my c++ program (using borland c 4.52) i get a message saying "unreferenced module 'main' in 'c0nt.asm'". also i get this same message with three different 32-bit i/o dlls. I assume this means there is a problem in the way i am including the library into my project. (i generated a .def and .lib file) and added it as a node on the project tree Has anyone used a 32-bit dll with borland C++ and can help ?? Thanx Tim Lunn
