    It's looking for main( ) because you have created a win32 console application instead of a win32 application probably. Just go into Project->Settings->Link .. then under Project Settings: look for the line:

    /subsystem:console

    and change that to

    /subsystem:windows

    You should be set. Next time make your project a Win32 Application , no console!

    Also, as you are creating an MFC app.....when you create the project chose MFC Application as opposed to Win32 Application or Console Application...this will bring in the nessasary settings and libraries
