Chat. Getting last message.

[furang]

I'm working on whisper signalizing.
I've reversed wow a bit and have found chat offset. It's 0x0117938C. And offset to the next mesage is 0x17C0. There are 60 messages saved in memory. Next one comes from the begginig. And so on.
Does someone happen to know how can i determine the last chat message?
As i've searched i haven't found the solution.
If they are <60 it's not a problem, but if they are >60....
PS. I'll contribute my code as soon as it gets work and looks like not so rude

Very nice links! 10x
But nothing new( I've looked through them and hadn't found the solution of my problem(

Now there's just one more problem, when you start up the client the first message will be at 0x104BCE4, the second at 0x104BCE4 + 0x17C0, third at 0x104BCE4 + (2*0x17C0) and so on...
This continues until the 60 message at (0x104BCE4 + (59*0x17C0)). If there's a new Chat-Message after this point the message will be stored at beginning again (0x104BCE4). However the old ones remain in memory until new messages overwrite them. The way I handled this, is just to check for different messages in between 2 reading loops, which seems to work well enough.

<Too short.>

Save all the messages to an array and check if they have changed when the 60th messaged is saved?

[furang]

I see. But it seems rather brute, isn't it?
But i guess it's the only one solution. Thanks all you.

[bolototo]

saves just whispers in a table and you compare them when there is a new post

Use WoW's LUA event system. Hook into whatever event is responsible for the type of chat you're after.

If all he is doing is memory reading then thats cool if you can use LUA even better! I am having trouble with this though...

I would really like to see your code if you will share it.

Thanks,

I'm not absolutely sure (not able to run WoW right now), but I think for 3.2 the current message index is at 0x011260EC. At least this one seems to be the only address whose content is multiplied by 17C0 in the client, and the function where this address is found also makes reference to 0x10CCB58 (which seems to be the base address to the chat array, there are 0x3c bytes before each string proper).

[furang]

You're damn right!!!
10x. But now i'm using method "diff between 2 loops".
Gonna post my code soon.

Public Sub DumpChat()

Dim retString As String = ""

For yy As UInt32 = 0 To 59
retString += Environment.NewLine & memReader.ReadString(New IntPtr(modEnums.wowChatOffsets.Firstmessage + (yy * modEnums.wowChatOffsets.NextMessage)))
Next
MessageBox.Show("Chat Dump" & Environment.NewLine & retString)

End Sub
