ReadUint64 failed

[mskc33]

Hey guys, maybe you can help me.
Im stuck with an error trying to read from WoW's memory and I have no idea why. VC# and WoW were both started as administrator and in 32-bit mode.

try {
    StaticClientConnection = BaseAddress + (uint)Pointers.ObjectManager.CurMgrPointer;
    CurrentTargetGUID = BaseAddress + (uint)Pointers.StaticPointers.CurrentTargetGUID;
    ClientConnection = Magic.ReadUInt(StaticClientConnection + (uint)Pointers.ObjectManager.CurMgrOffset);
    FirstObject = Magic.ReadUInt(ClientConnection + FirstObjectOffset);
} catch (Exception ex) {
    setStatus("Exception while finding the first object");
    log("Exception while finding 'FirstObject': (BaseAddress=" + BaseAddress + ") (StaticClientConnection=" + StaticClientConnection + ") (CurrentTargetGUID=" + CurrentTargetGUID + ") (ClientConnection=" + ClientConnection + ")");
}

And I'm getting the exception:

ReadUint64 failed
Exception while finding 'FirstObject': (BaseAddress=4194304) (StaticClientConnection=17276128) (CurrentTargetGUID=16582576) (ClientConnection=0)

Im using WoW Version 3.3.5 Build 12340 and these are my offsets:

        internal enum General {
            IsInGame = 0x00BD0792,
        }

        internal enum StaticPointers {
            CurrentTargetGUID = 0x00BD07B0,             // 3.3.5a 12340
            LocalPlayerGUID = 0x00CA1238,               // 3.3.5a 12340
        }

        internal enum ObjectManager {
            CurMgrPointer = 0xC79CE0,                 // 3.3.5a 12340
            CurMgrOffset = 0x2ED0,                      // 3.3.5a 12340
            NextObject = 0x3C,                          // 3.3.5a 12340
            FirstObject = 0xAC,                         // 3.3.5a 12340
            LocalGUID = 0xC0                            // 3.3.5a 12340
        }

Any idea?

Have you checked if your offsets are 100% right?

[mskc33]

I think so. As seen in this post: http://www.ownedcore.com/forums/worl...ml#post1917706 ([WoW][3.3.5.12340] Info Dump Thread)

Maybe it's the way I'm reading the ClientConnection. I just tested the same code on Vanilla WoW (with different offsets ofcourse) and it works fine. Has anything in this regard changed from 1.12.1 to 3.3.5a?

[flowtek333]

i do not know much about that patch sry. but you could try a diffrent way to reading clientconnection and see if you get the same problem?

[mskc33]

What different way?

// Edit: I just read since 3.3.5a I have to add the "WoW Base". What is this and how can i read it?

[flowtek333]

IntPtr baseAddress = WowProcess.MainModule.BaseAddress;

this will add the wow base address

edit: it may be the problem in your code

[mskc33]

But I'm already adding the BaseAddress to the CurMgrPointer. Anywhere else I need to add it?

[flowtek333]

Sorry i cant see the problem right now.. give me some time to look it threw

//edit: try change the FirstObject = Magic.ReadUInt(ClientConnection + FirstObjectOffset);

to: FirstObject = Magic.ReadUInt(Baseaddress + FirstObjectOffset);

works?

[mskc33]

The problem is, the ClientConnection is 0 and I don't know why. If you want, I can upload my whole project?

[flowtek333]

mskc33 i do not know much about ClientConnection but you can upload it all to let people see and maybe help you with the problem you may have.

This is how it works with 3.3.5:

            CurrMgr = 0x00C79CE0,
            CurrMgrEx = 0x2ED0,
            FirstObjectOffset = 0xAC,

            ObjectManager = Magic.ReadUInt((uint)(Magic.ReadUInt((uint)(BaseAddress + ClientOffsets.CurrMgr)) + ClientOffsets.CurrMgrEx));
            FirstObject = Magic.ReadUInt((uint)(ObjectManager + ClientOffsets.FirstObjectOffset));

(taken from an old source)

Still doesn't work. I uploaded my code to pastebin:

[C#] Game.cs - Pastebin.com (the ReadUint64 failed happens in line 59)
[C#] Pointers.cs - Pastebin.com

I think I'm missing something very obvious here ... :confused:

Sorry dude, I've opend the cataclysmn source.

This one should now work properly:

            StaticClientConnection = Magic.ReadUInt((uint)0x00C79CE0);
            ClientConnection = Magic.ReadUInt((uint)(StaticClientConnection + (uint)0x2ED0));
            FirstObject =  Magic.ReadUInt((uint)(ClientConnection + (uint)0xAC));

            FirstObject =  Magic.ReadUInt((uint)(ClientConnection + (uint)0xAC));

And what about the BaseAddress?
