I'm use ReadProcessMemory to read Pointer in Step 8 Cheat Engine Tutorial

Code:

Private Sub cmdTest_Click()
Dim Game As Long, ProcessID As Long, Handle As Long
Dim lngTest1 As Long

Handle = FindWindow("TForm9", "Step 8")
If Handle <> 0 Then
GetWindowThreadProcessId Handle, ProcessID
hProc = OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID)
If hProc <> 0 Then
Dim lngAddress As Long
lngAddress = &H45CC18 + &HC
ReadProcessMemory hProc, lngAddress, VarPtr(lngTest1), 4, 0&
MsgBox lngTest1
End If
End If
End Sub

But it's return 0.
If i change

Code:

ReadProcessMemory hProc, lngAddress, lngTest1, 4, 0&

Code:

ReadProcessMemory hProc, lngAddress, lngTest1, 3, 0&

It's return FFFFFF.

So how can i read 4 byte value from an address. Question

GetWindowThreadProcessId Handle, ProcessID
hProc = OpenProcess(PROCESS_ALL_ACCESS, False, ProcessID)

Dim lngAddress As Long
lngAddress = &H45CC18 + &HC
ReadProcessMemory hProc, lngAddress, lngTest1, 4, 0&
MsgBox lngTest1
End If
End If
End Sub

This should work just fine by the looks of it ...
It reads 4 bytes from &H45CC18 + &HC which is &H45CC24 and stores the value in lngTest1.
I don't know why you used VarPtr =/
