Base Address: 0a200e68
Offset: 30
I can't figure out how to read it =/
Any way I try even if it compiles it doesn't return the correct value.

Not exact code but you'll get the idea:
intptr base;
intptr addy;
ReadProcessMemory (0x0a200e68, &base, 4)
ReadProcessMemory(base+0x30, &addy, 4)

Erm, I understand what you are trying to say but perhaps a slightly more complete snippet would give me a better concept of the idea.

| Code: |
IntPtr Base = 0x0A200E68, Offset = 0x30;
int BaseValue,OffsetValue,dwReadBytes;
ReadProcessMemory(Process.Handle,Base,out BaseValue,4,out dwReadBytes);
ReadProcessMemory(Process.Handle,BaseValue + Offset,out OffsetValue,4, out dwBytesRead);
|
i'm pretty sure in C# it goes like that

Can I see the signature you use to import?
I seem to have a different one.

| Code: |
//using System.Runtime.InteropServices;
[DllImport("kernel32.dll", SetLastError = true)]
internal static bool ReadProcessMemory(
IntPtr hProcess,

ount uint lpNumberOfBytesRead
);
public int ReadValue(IntPtr hProcess)
{
byte[] val = new byte[4]; uint BytesRead;
if (!ReadProcessMemory(hProcess, 0x0A200E68, ref val, 4, out BytesRead) || BytesRead != 4)
throw new Exception("Unable to read process! Error code: " + Marshal.GetLastWin32Error());
if (!ReadProcessMemory(hProcess, BitConverter.ToInt32(val, 0) + 0x30, ref val, 4, out BytesRead) || BytesRead != 4)
throw new Exception("Unable to read process! Error code: " + Marshal.GetLastWin32Error());
return BitConverter.ToInt32(val, 0);
}

you probably opened your process with PROCESS_ALL_ACCESS flag
you should use PROCESS_VM_READ flag

GetWindowThreadProcessId(WindowHandle, out ProcID); // Get the Process ID (PID) from the targeted window/window class

this.Text = ReadValue(ProcessHandle).ToString();
