I made this code for 3D Effect in a Game, this code help change Possition and Zoom In + Out the screen!

But if I run it on win 7 64 bits, when scroll the mouse wheel, both forward and backward, it Zoom In only but it works correctly when run on Windows 7 32 bits!

How can I fix it for any win?
Thanks for any help!!!!
