Unresolved Extrernal symbol problem.

[EDN Admin]

i am back again to ask another question.

i used this tutorial http://msdn.microsoft.com/en-us/library/bb384843.aspx" target="_blank
here
and i followed each step to the note. but im getting this :

error LNK2019: unresolved external symbol "long __stdcall WndProc(struct HWND__ *,unsigned int,unsigned int,long)" (?WndProc@@YGJPAUHWND__@@IIJ@Z) referenced in function _WinMain@16
the only parts of the code i have edited are the application title and adding buttons to the msgboxs
