Basic windows programming

I'm doing a lesson from a book call "Tricks of the Window Game Programming Gurus", where it trys to teach you how to make the basic parts of a window.
Sorry for cloggin the place up with comments but thats how I remember what the certain things do.
However, when linking the file i get 2 errors:

Code:

Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/Demo.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

Demo.exe - 2 error(s), 0 warning(s)

heres my code

Any suggestions? Oh yeah, I'm usin Visual C++.

I think, while creating project, you have choosen 'Win32 Console application'. And that is the reason, it is showing up the error.

Create Win32 Application..

Hopefully that will sovle this problem

aww man, you were right on the money.

TY roaring tiger

Also, GetMessage() returns one of THREE values: positive, zero, or negative (if an error occurs). So unless you want an infinite loop on error, change to:

while(GetMessage() > 0)
