Subj : Using a Class from the main App in a DLL To : borland.public.cpp.borlandcpp From : "M.Kenner" Date : Wed Apr 14 2004 02:25 pm How can i use a Class from the main App in a DLL ? I have written a application with classes. For example a class for serial-communication. The class works inside the app very fine. Now i want write some dll's with some special funktion, which i load dynamically. This DLL's must use classes inside the main app and have a own Form. For Example a Form with Button which execute a function from a class (serial com) inside the app. How can I programm what ? Thanks .
