How do I code pointers in Visual Basic? (Relating to Cheat Engine) I'm so confused!
I use Cheat Engine and in Cheat Engine you have Memory Addresses and Pointers. In Cheat Engine I got my Memory and Pointers to work just fine.
Now trying to do this Visual Basic is a pain. I must be misunderstanding something. This is what Cheat Engine has and this is what I am trying to code in Visual Basic:
Here is the code I am trying:
Variables:
Code:
Code:
baseaddress = 00007FF73EE70000
GV.addresses = 01DB81B0
pointer = A4
When I add 'baseaddress' and 'GV.addresses' I get: '7FF740C281B0 ' Which is Mathematically correct.
Now I know a Pointer points to a Memory Address that has a Memory Address in it which is a 4Byte. Then you read that address and add the pointer.
My Code will show the correct value of '00007FF73EE70000' + '01DB81B0' (which is '7FF740C281B0')
Code:
Code:
Dim testt As Long
testt = (Convert.ToInt64(baseaddress, 16) + (GV.addresses))
MsgBox(Hex(testt))
But no matter how much I play with '7FF740C281B0' I can't get Cheat Engines Value of '1C6B64B70F4'.
I thought it worked like you read the Address in Hex stored at '00007FF73EE70000' + '01DB81B0' (baseaddress + GV.addresses). Then you take that addressed that is stored there and add the pointer 'A4'.
But the value in Cheat Engine stored at ('00007FF73EE70000' + '01DB81B0') is '3058397264'
And none of those will point to '1C6B64B70F4'.
I need to get the Address '1C6B64B70F4' to add the pointer of 'A4'
What am I doing wrong here????
I am so confused on this... Can anyone help sort this mess out for me?
AND OF COURSE THANKS IN ADVANCED!
I hope that because I am referencing Cheat Engine here that it does not break any rules. But I am relating this to a Visual Basic issue, so I thought it would be ok. If not, I apologize.
PLEASE NOTE:
I should note that this has NOTHING TO WITH CHEATING in a game. I am trying to read memory addresses in a game and display them to help keep track of a Characters Progress.
I am reading variables such as HP, MP, and Coordinates. I then want to store the variables and keep track of there changes.
I am not trying to modify any memory addresses.
I am just reading memory addresses.

Re: How do I code pointers in Visual Basic? (Relating to Cheat Engine) I'm so confuse
what is pointer defined as and is A4 a literal value or a variable?
Always use [code][/code] tags when posting code.

Here is the complete listing of the source code: (just copy it into a project and run it).
HTML Code:
Option Explicit
Private Declare Sub CopyMemory Lib "kernel32" _
Alias "RtlMoveMemory" (Destination As Any, _
Source As Any, ByVal Length As Long)
Private Declare Function GetProcessHeap Lib "kernel32" () As Long
Private Declare Function HeapAlloc Lib "kernel32" _
(ByVal hHeap As Long, ByVal dwFlags As Long,_
ByVal dwBytes As Long) As Long
Private Declare Function HeapFree Lib "kernel32" _
(ByVal hHeap As Long, ByVal dwFlags As Long, lpMem As Any) As Long
Private Declare Sub CopyMemoryWrite Lib "kernel32" Alias _
"RtlMoveMemory" (ByVal Destination As Long, _
Source As Any, ByVal Length As Long)
Private Declare Sub CopyMemoryRead Lib "kernel32" Alias _
"RtlMoveMemory" (Destination As Any, _
ByVal Source As Long, ByVal Length As Long)
Private Sub Form_Load()
Dim ptr As Long 'int * ptr;
Dim hHeap As Long
hHeap = GetProcessHeap()
ptr = HeapAlloc(hHeap, 0, 2) 'an integer in Visual Basic is 2 bytes
If ptr <> 0 Then
'memory was allocated
'do stuff
Dim i As Integer
i = 10
CopyMemoryWrite ptr, i, 2 ' an intger is two bytes
Dim j As Integer
CopyMemoryRead j, ptr, 2
MsgBox "The adress of ptr is " & CStr(ptr) & _
vbCrLf & "and the value is " & CStr(j)
HeapFree GetProcessHeap(), 0, ptr
End If
End Sub
