Error!!!

Code:
LIBCMTD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
I am trying to rig a project I already have going, which was created as a console application.
I basically added winmain and it's not recognizing it as the main function.

Is there any way I can change my project settings (vs2005 express) to support my new main function?

Or do I have to create a windows application from scratch?
