Address Value Changer. (Like Cookies)

[Jorndel]

Well, won't do much.
Basically the same as for cookies dll.

(PS: Would be nice with a comment. Ask if you want snippets.)

Do it in a DLL project. OR, change it for your purpose. (Need some removing and editing.)
(If you have used Cookies DLL, then you understand how to use this in a WinForm Project.)

Good Luck guys, just ask if anything needed.
