Hi I need read values from memeory using ReadProcessMemory win API what get for now is Code: Dim ptrWindowLoc As IntPtr ptrWindowLoc = FindWindow(Nothing, TextBox1.Text) Label3.Text = ptrWindowLoc.ToString Dim WindowThreadIdentifier As IntPtr Dim WindowProcessIdentifier As IntPtr WindowThreadIdentifier = GetWindowThreadProcessId(ptrWindowLoc, WindowProcessIdentifier) Label5.Text = WindowThreadIdentifier.ToString Label7.Text = WindowProcessIdentifier Dim process As IntPtr process = OpenProcess(PROCESS_VM_OPERATION Or PROCESS_VM_READ Or PROCESS_VM_WRITE Or _ PROCESS_QUERY_INFORMATION, False, WindowProcessIdentifier.ToInt32) Label9.Text = process.ToString Dim lvi As LVITEM = New LVITEM Dim ptrVirtualAddress As IntPtr Dim _ptrVirtualAddress As IntPtr = IntPtr.Zero 'ptrVirtualAddress = VirtualAllocEx(process, IntPtr.Zero, Marshal.SizeOf(GetType(LVITEM)), MEM_COMMIT and , PAGE_READWRITE) ptrVirtualAddress = VirtualAllocEx(process, IntPtr.Zero, 512, &H2000, PAGE_READWRITE) If ptrVirtualAddress = IntPtr.Zero Then Throw New SystemException("Failed to allocate memory in remote process") End If 'problem section Dim a As IntPtr = IntPtr.Zero Dim buffer(512) As Byte Dim x As Int32 = ReadProcessMemory(process, &H234343, buffer, 512, a) Dim strf As String = "" Dim i As Integer For i = 0 To 500 strf = strf + buffer(i).ToString Next MessageBox.Show(strf) the problem is i dont understand the read process parameter how can i get the pointer to value i want if i only have a running process Any 1 can help ThaNKS
