reading memory address

Question

How is this possible? For example, the following address: "00775BD7" shows how HP has a player in the game Counter Strike 1.6
So how do I get the value?

If it is not clear;
I want to read only

Answer 1

..net isn't really a good platform for this task, since the platform uses a virtual compiler to manage all memory uses (thats what makes .net type-safe). you need to use "unmanaged code" to read a block of memory raw.

This may get you started, but the code is Ms vC++.

note that you may be able to do this in a .net langague, but it will involve importing a windows API library, just like the sample above.

I found an example(works well):

Imports System.Runtime.InteropServices

Public Class Form1
    Private Declare Function ReadProcessMemory Lib "kernel32" Alias "ReadProcessMemory" (ByVal hProcess As Integer, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Integer, ByVal nSize As Integer, ByRef lpNumberOfBytesWritten As Integer) As Integer
    Private Declare Function CloseHandle Lib "kernel32" Alias "CloseHandle" (ByVal hObject As Integer) As Integer
    Private Declare Function OpenProcess Lib "kernel32" Alias "OpenProcess" (ByVal dwDesiredAccess As Integer, ByVal bInheritHandle As Integer, ByVal dwProcessId As Integer) As Integer
    Public Function ReadLong(ByVal ProcessN As String, ByVal Address As Integer, ByVal ByteL As Byte) As Long
        Dim value As Long
        Dim proc As Process = Process.GetProcessesByName(ProcessN)(0)
        Dim winhandle As IntPtr = OpenProcess(&H1F0FFF, True, proc.Id)

        If ReadProcessMemory(winhandle, Address, value, ByteL, 0) = 0 Then Return -1
        CloseHandle(winhandle)
        MsgBox(value)

        Return value
    End Function


    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        ReadLong("hl", &H3D53394, 4)
    End Sub
End Class

So that's my main problem has been resolved, but then another problem arose.

Now,I searched for some text:

The result I get is wrong(in my code, not on Chat Engine), of course, because the type should be text and not Byte.

So I need get type "text", and not "Byte" to solve it...

What can I do?

text info is stored in binary or hex, without any encoding. in order to turn it into text, you need to encode it with whatever scheme the data was originally in (ASCII and Unicode are the two most common text encoding types. )

this should get you started with en/decoding text stored in binary:
