C# - Reading Chats

[drakylucas]

Hello guys, here is a function for read chat in C#
you need GUI_POINTER address, you can get this in
http://www.blackdtools.net/showthrea...ddresses-10-71
"tibiachatlog_selchannel" is this.

so, Now, the function..

       public static uint GUI_POINTER= 0x8353A0 - 0x400000 + Kernel.Client.BaseAddress;
       public List<List<string>> readChatMessages(System.IntPtr handle, string channel)
        {
        List<string> mensagens = new List<string>();
        List<string> senders = new List<string>();

		List<List<string>> ret = new List<List<string>>();
		uint pointer;
		bool foundChannel = false;

        pointer = Memory.ReadUInt32(handle, GUI_POINTER);
        if (pointer == 0)
        {
	        return ret; // GUI Pointer is returning 0. Reasons could be that the character is not logged in.
        }

		pointer = Memory.ReadUInt32(handle, pointer + 0x40);
        pointer = Memory.ReadUInt32(handle, pointer + 0x38);	
		while (pointer > 0)
		{
				uint channelPointer;
				string channelName;
                channelPointer = Memory.ReadUInt32(handle, pointer + 0x24);
                channelPointer = Memory.ReadUInt32(handle, channelPointer + 0x10);
                

                channelName = Memory.ReadString(handle, Memory.ReadUInt32(handle, pointer + 0x2C));
            if (string.Compare(Convert.ToString(channelName), Convert.ToString(channel)) == 0)
				{
						foundChannel = true;

						while (channelPointer > 0)
						{
								/* We have found our desired channel pointer. We will retrieve all data for demonstration but only storing the actual messages */
								string sender;
								string message;
								string level;
								string time;
								byte type;
							    type = Memory.ReadByte(handle, channelPointer + 0x4);
                                sender = Memory.ReadString(handle, channelPointer + 0x14);
                                message = Memory.ReadString(handle, Memory.ReadUInt32(handle, channelPointer + 0x4C));
                                level = Memory.ReadString(handle, channelPointer + 0x3c);
                                time = Memory.ReadString(handle, channelPointer + 0x8);


                                mensagens.Add(message);//aqui
                                senders.Add(sender);
								//ret.push_back(message); // Store the message

								channelPointer = Memory.ReadUInt32(handle, channelPointer + 0x5C);
						}
				}
                if (foundChannel)
                    break;

                pointer = Memory.ReadUInt32(handle, pointer + 0x10);
                
        }
        ret.Add(mensagens);
        ret.Add(senders);
        return ret;
        }

(sorry for this identation, in my Visual studio, all is correctly)


this function returns two lists inside of an other list..
for use this function, i'm using like this:

            // this functions is the name of class where is located the readChatMessages
            functions read = new functions();

            List<List<string>> retorno = read.readChatMessages(Client.Handle, "Local Chat");
            List<string> mensagens = retorno[0];
            List<string> senders = retorno[1];
            if (mensagens.Count != 0 && senders.Count != 0)
            {
                   //do whatever you want here
                   for(int i = 0; i < mensagens.Count; i++)
                       Console.WriteLine("sender: " + senders[i] + " - full message: " +mensagens[i]);
            }

Draky, thanks for posting it!

I'm not into Pointers yet, but its nice to have this code in C#. Thanks again!

But if you allow me, i'd like to make some comments about your C# code.

A List<List<>> is basically a matrix, which is one of the worst programming techniques that you can use. It turns the code into a bloody mess.

As C# allows OOP, you definately should use it to make your code faster and readable.

Eg.:

I've created a class called Channel which stores:
-Name of the Channel (eg.: "Server Log")
-A List<Message> with every message read from this Channel

public class Channel
    {
        public string Name { get; set; }
        public List<Message> Messages { get; set; }
    }

On the other hand, Message class has the following properties:

public class Message
    {
        public Channel Channel { get; set; }

        public byte Type { get; set; }

        public string Sender { get; set; }

        public string Text { get; set; }

        public string Level { get; set; }

        public string Time { get; set; }

    }

Finally, my ReadChannels function returns a List<Channel>, which makes it fareasier to read the channels and it's messages.

List<Channel> result = _client.ReadChannels();

foreach (Channel _channel in result)
{
     Console.WriteLine(String.Concat("[", _channel.Name, "]"));
 
     foreach (Message _msg in _channel.Messages)
     {
          Console.WriteLine(_msg.Text);
      }
}

So, if you got interested on the improvements i've made, take a look at the project attached. I've create it on Visual Studio 2010.

      }

nice code, i am having problems disecting the chatlog structure, could you explain how you got the offsets in your code? the first 2 changes to the pointer in your code add 0x40 and 0x38 to gui pointer, then goes on to find channel pointer/offsets for message ect, but when i manually add this in cheat engine it just comes up with 0's, but the solution loads fine so i know the gui pointer is correct, any ideas?
