I'm working on some project and I want to write multiple .c files (each .c file for a dialog). Now I have main.c and about.c files and if I want to compile this I get these errors:
About.obj : error LNK2005: _szAppName already defined in main.obj
Release/Address Book.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.
What is wrong and how to use multiple files?
I'm using Visual C++ 5.0 on Win98.
