[Tutorial] How to VB.Net your trainer

Hello MPGH. I was writing module for VB.Net cause kyos tut interested me. However in kyo tut it was pretty strange lol. And there were a lot of problems with it. So i wrote a module, becouse copying and pasting code between subs and buttons sux, doesnt it? Now u will be able to change memory in 1 line of text (for pointers u'll need more :P). Pointers same as for VB6, read then add the offset and voila.

However reading isnt the same, here i got public variables storing read values. It is better becouse u dont need to declare variable every time u wanna read from some address. So reading will look like this (for byte, 2bytes, 4bytes, 8bytes):

Code:

ReadMemory(“someapp”, &Haddress)
Textbox1.Text = vBuffer

and for float:

Code:

ReadFloat(“someapp”, &Haddress)
Textbox1.Text = vBufferS

but before u can put ur greedy fingers on my module u need to figure out some parts of it. They were replaced with xxxxxx. Without figuring it out module won't work. Don't worry, errors displayed by VB will help you

And here comes the module:

Code:

Option Explicit On
Imports System
Imports System.diagnostics
Module ReadWriteMem
    Public vBuffer As Long 'public variable storing read values for Byte, 2 Bytes 4 Bytes and 8 Bytes
    Public vBufferS As Single 'public variable to store read floating point values

    'stuff
    Public Declare Function KeyPressed Lib "user32" Alias "GetAsyncKeyState" (ByVal Key As Integer) As Integer
    Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
    'reading
    Private Declare Function ReadMem Lib "kernel32" Alias "xxxxxx" (ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByRef buffer As Long, ByVal size As Int32, ByRef lpNumberOfBytesRead As Int32) As Boolean
    Private Declare Function ReadFloat Lib "kernel32" Alias "xxxxxx” (ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByRef buffer As Single, ByVal size As Int32, ByRef lpNumberOfBytesRead As Int32) As Boolean
    'writing
    Private Declare Function WriteMem Lib "kernel32" Alias "xxxxxx" (ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByVal buffer() As Long, ByVal size As Int32, ByRef lpNumberOfBytesRead As Int32) As Boolean
    Private Declare Function WriteFloat Lib "kernel32" Alias "xxxxxx " (ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByVal buffer() As Single, ByVal size As Int32, ByRef lpNumberOfBytesRead As Int32) As Boolean

    Private appProcess As Process

    Private Function SetProcess(ByVal ProcessName As String) As Boolean
        Dim processes As Process() = Process.GetProcessesByName(ProcessName)
        If (processes.Length > 0) Then
            appProcess = processes(0)
            Return True
        Else
            Return False
        End If
    End Function

    Public Function WriteMemory(ByVal appName As String, ByVal address As Integer, ByVal value As Object, ByVal bytes As Integer)
        If SetProcess((xxxxxx)) = False Then
            MsgBox(xxxxxx & " not found.", MsgBoxStyle.Critical, "Error")
            End
            Exit Function
        End If

        Dim buffer() As Long = New Long(0) {value}

        Return WriteMem(xxxxxxx.Handle, address, buffer, bytes, Nothing)

        CloseHandle(xxxxxxx.Handle)
    End Function

    Public Function ReadMemory(ByVal appName As String, ByVal address As Integer, ByVal bytes As Integer)
        If SetProcess((xxxxxxx)) = False Then
            MsgBox(xxxxxxx & " not found.", MsgBoxStyle.Critical, "Error")
            End
            Exit Function
        End If

        ReadMem(xxxxxxx.Handle, address, vBuffor, bytes, Nothing)

        Return vBuffer

        CloseHandle(xxxxxxx.Handle)
    End Function

    Public Function WriteFloat(ByVal appName As String, ByVal address As Integer, ByVal value As Single)
        If SetProcess((xxxxxx)) = False Then
            MsgBox(xxxxxx & " not found.", MsgBoxStyle.Critical, "Error")
            End
            Exit Function
        End If

        Dim buffer() As Single = New Single() {value}

        Return WriteFloat(xxxxxxx.Handle, address, buffer, 142, Nothing)

        CloseHandle(xxxxxxx.Handle)
    End Function

    Public Function ReadFloat(ByVal appName As String, ByVal address As Integer)
        If SetProcess((xxxxxx)) = False Then
            MsgBox(xxxxxx & " not found.", MsgBoxStyle.Critical, "Error")
            End
            Exit Function
        End If

        ReadMem(xxxxxxx.Handle, address, vBufferS, 834, Nothing)

        Return vBufferS

        CloseHandle(xxxxxxx.Handle)
    End Function

End Module

There are no comments since a few days ago my comp crashed and i lost whole module. When rewritting i didnt want to bother rewriting them.

btw except for xxxxxx-ed parts there are 2 code traps. :P But while reading u should notice them since they are kinda obvious (if u understand the code)

Thanks for posting. I'll start messing around with VB.Net right now.

Cheers for posting the TUT ill have to try it out sometime maybe tommorrow

well if u find the xxxxxx-ed parts too hard to figure out, just say it, i'll try to make it easier or consider removing it completely..

Omg, n00bz..

just give me credits in your trainers...

thx very much mate. Really wanted this for a long time. Going to make a new hack now.

How can I Freeze a value in Visual studio 2005? I can´t put a timer on interval 0. Then it gives me an error. What should I use instead?

thanks ill try it later
