how to write/Read game memory with vb 2008

[CodeHPro]

this tut will show you how to read & write memory in any game
first go to vb 2008 add a module paste this into it

Module Memory

    End Sub
End Module

then go to your form add a button to read the address name it "read" and add a label then double click the read button you just made and paste this code

     
'if your address you got from Cheat Engine or anything else has 
gamename+address then use this 
 Label1.Text = ReadInt((BaseAddress + put address here))
'if it doesn't have the + then use this 
 Label1.Text = ReadInt((put address here))

now add a button to write to the address
then paste this

'again if the address had + then use this
WriteInt((BaseAddress + 5350952), value you want to set it to)
if it didnt have + then use this 
WriteInt((5350952), value you want to set it to)

now paste this code in your form load event

  Dim MyProcess As Process() = Process.GetProcessesByName("halo2") ' Replace that with the games window text
        Dim mainModule As ProcessModule
        mainModule = MyProcess(0).MainModule
        BaseAddress = CInt(mainModule.BaseAddress)
        BaseAddress = CInt(mainModule.BaseAddress)

add this code right under where it says
Public Class form1

Dim BaseAddress As Integer
    Dim MyProcess As Process() = Process.GetProcessesByName("halo2") ' Replace that with the games window text

and your done! if you have any other questions add me on Xfire or msn

here are some pic;s of what it should look like when your done
