I'm trying to make a trainer in Visual Basic 2010 and I want to know how to write arrays of byte to addresses in different processes. I assume you use WriteProcessMemory or you can get a module from somewhere to add to my project.

API
Code:
Declare Function WriteProcessMemory Lib "kernel32" (ByVal hProcess As IntPtr, ByVal lpBaseAddress As Integer, ByVal buffer As Byte(), ByVal size As Integer, ByVal lpNumberOfBytesWritten As Integer) As Boolean


A very simple function, no pointers or modules.
Code:
    Function WriteBytes(ByVal ProcessName As String, ByVal Address As Integer, ByVal Bytes2Write As Byte()) As Boolean
        Dim Proc As Process() = Process.GetProcessesByName(ProcessName)
        If Proc.Length = 0 Then
            Return False
        End If
        Return WriteProcessMemory(Proc(0).Handle, Address, Bytes2Write, Bytes2Write.Length, 0)
    End Function


All you need now is the process name, address you're writing too and the array of bytes you wanna write.

example
Code:
WriteBytes("SomeGame", &H4000000, New Byte() {&H90, &H90, &H90, &H90, &H90})

Just change it to whatever you need.
