Windows GUI programs begin at the function WinMain.  OWL programs begin at
the function OwlMain.  EasyWin programs begin at the function main (and are
static linked).

I don't think you are writing an OWL program since it already has things
such as you show in that class and more.  You can't be creating an EasyWin
program because if you were you would already have created a function main,
so you must be trying for a normal Windows GUI program.

Right click on the EXE name in the project window and select TargetExpert
from the menu which appears.  In the TargetExpert dialog adjust the type of
target to be the type you intended.
