Need Help with This program

Hey all i to complie a program that i copied out of a book, however when i do i get this error :
--------Configuration: skeleton - Win32 Debug-------
Compiling...
skeleton.cpp
C:\Documents and settings\NTD\My Documents\skeleton.cpp(7) : error c2146: syntax error : missing ';' before identifer 'CALLBACK'
C:\Documents and settings\NTD\My Documents\skeleton.cpp(7) :error c2501: 'LRESULT' : missing storage-class or type specifiers
C;\Documents and settings\NTD\My Documents\Skeleton.cpp(7) : fatal error c1004: unexpected end of file found
Error executing cl.exe

Line 7 looks like this: LRESULT CALLBACK WndProc(HWND hWindow, UINT msg, WPARAM wParam, LPARAM lParam);

Since i copied the code from a book i then decided to use the CD-ROM and change the cpp files i did and when i complied it i got these errors:-

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

I am using windows.h for the header file. And the books cd comes with Borland C++ but i already have Microsoft's one would that make a difference?

-------By the way----------
