Here is a module i use for VB
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Integer, ByVal bInheritHandle As Integer, ByVal dwProcessId As Integer) As Integer

and this is an exemple on how to use it :
WriteFloatPointer(&hADRESS, &HOFFSET, tweak.Text)
But before, learn how to use cheat engine. there is many tutorials on youtube.
