Base pointers!

[marekrndr]

I've cracked my head on this long enough to finally ask for any help.

Below I've included an image containing the 'Addresses' of the values I need. As my VB.NET memory reading application is not that advanced it needs the base pointers to grab the values from in-game.


Can someone point me to the correct direction to get these?

Usually you work with Pointer in C++, not vb.

If I remember right, you have the functions "WriteProcessMemory" & "ReadProcessMemory" (not sure about the Read[...], I never used such things in C#).

This is how it would look in C++ (I took it from a Tut here, because I like that function xD)

void CMemory::m_Lesen(void)
{
	if (pWnd = CWnd::FindWindowExW(NULL,NULL,NULL,_T("PROCESSNAME-HERE"))) { 

		hWnd = HWND(pWnd->GetSafeHwnd());  

	}else{ 
		AfxMessageBox(_T("Fenster nicht gefunden!")); 
	}
	UpdateData(true);  
	//unsigned long address1 = 0x0015B778; 
	//unsigned long offset = 0x00000014; 
	unsigned long address1 = 0xFF7D0FB8; 
	unsigned long offset = 0x170; 
	unsigned long address2 ; 
	int value ; 

	DWORD numBytesRead; 
	HANDLE hProc; 
	DWORD procID;  
	GetWindowThreadProcessId(hWnd,&procID);  
	hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID);  
	ReadProcessMemory(hProc, (LPCVOID)address1, &address2, sizeof(long), &numBytesRead);  
	address2 = address2+offset ;  
	ReadProcessMemory(hProc, (LPCVOID)address2, &value, sizeof(int), &numBytesRead);  
	m_Value.Format(_T("%i"),value);  
	UpdateData(false);  
	CloseHandle(hProc);  
}


void CMemory::m_schreiben(void)
{
	if (pWnd = CWnd::FindWindowExW(NULL,NULL,NULL,_T("PROCESS-NAME"))) { 

		hWnd = HWND(pWnd->GetSafeHwnd());  

	}else{ 
		AfxMessageBox(_T("Fenster nicht gefunden!")); 
	}
	UpdateData(true);  
	unsigned long address1 = 0xFFAA5F78; 
	unsigned long offset = 120; 
	unsigned long address2 ; 
	int value ; 

	DWORD numBytesRead; 
	HANDLE hProc; 
	DWORD procID;  
	GetWindowThreadProcessId(hWnd,&procID);  
	hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID);  
	ReadProcessMemory(hProc, (LPCVOID)address1, &address2, sizeof(long), &numBytesRead);  
	address2 = address2+offset ;  
	value = _wtoi (m_Value);  
	WriteProcessMemory(hProc,(LPVOID)address2,&value,sizeof(value),NULL);  
	m_Value.Format(_T("%i"),value);  
	UpdateData(false);  
	CloseHandle(hProc);  
}

Jep, I'm more confused as I was before.


To make things more clear - I only need to read the memory.

C#:

[DllImport("kernel32.dll")]
static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, byte[] lpBuffer, UIntPtr nSize, ref uint lpNumberOfBytesWritten); // including WinAPI function

public byte[] vReadMemory(IntPtr handle, IntPtr baseAdress) // handle would be your Process, the BaseAdress would be the Pointer
{
	byte[] bytes = new byte[24]; // The Output
	uint size = sizeof(int); 
	uint rw = 0;
	ReadProcessMemory(handle, (IntPtr)baseAdress, bytes, (UIntPtr)size, ref rw);
	return bytes; // remember to convert them to an int / string.
}

vb.net:

	Dim rw As UInteger = 0
	ReadProcessMemory(handle, DirectCast(baseAdress, IntPtr), bytes, DirectCast(size, UIntPtr), rw)
	Return bytes

End Function

And to read the memory I was planning to use this :

Label1.Text = ReadInt((BaseAddress + POINTER))

The actualy problem is that I can't find the pointer for it.. I only have the mere address.
