Unable to get text from window

[fattysc]

I've been trying to get text from a certain window. I'm fairly certain I'm really close. So maybe someone can give me a little push in the right direction.

namespace MW2KICKER
{

    public partial class MW2KICKER : Form
    {
        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);
        [DllImport("user32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Ansi)]
        public static extern IntPtr FindWindow(string className, string windowName);
        [DllImport("user32.dll", SetLastError = true)]
        public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, IntPtr windowTitle);
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        static extern IntPtr SendMessage(IntPtr hWnd, Int32 Msg, IntPtr wParam, StringBuilder lParam);
        [DllImport("User32.Dll", EntryPoint = "PostMessageA")]
        static extern bool PostMessage(IntPtr hWnd, uint msg, int wParam, IntPtr lParam);
        [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
        static extern int GetWindowTextLength(IntPtr hWnd);
        



        private const int WM_SETTEXT = 0x000C;
        private const int VK_RETURN = 0x0D;
        private const int WM_KEYDOWN = 0x100;
        private const int WM_KEYUP = 0x101;
        private const int WM_GETTEXTLENGTH = 0x000E;
        private const int GW_CHILD = 5;
        private const int GW_HWNDNEXT = 2;

        public MW2KICKER()
        {
            InitializeComponent();
        }

        private void bStatus_Click(object sender, EventArgs e)
        {
            //Find the console edit box aswell as send the status command - works fine.
            string message = "status";
            StringBuilder sb = new StringBuilder(message);
            IntPtr MW4CONSOLE = FindWindow("IW4 WinConsole", null);
            IntPtr MW4EDIT = FindWindowEx(MW4CONSOLE, IntPtr.Zero, "Edit", IntPtr.Zero);
            SendMessage(MW4EDIT, WM_SETTEXT, IntPtr.Zero, sb);
            PostMessage(MW4EDIT, WM_KEYDOWN, VK_RETURN, IntPtr.Zero);
            PostMessage(MW4EDIT, WM_KEYUP, VK_RETURN, IntPtr.Zero);

            //Get the console text - works and finds the correct window - cross checked with api spy
            IntPtr MW4TEXT = FindWindowEx(MW4CONSOLE, MW4EDIT, "Edit", IntPtr.Zero);

            //does not work
            int length = GetWindowTextLength(MW4TEXT);
            StringBuilder sbtext = new StringBuilder(length + 1);

            GetWindowText(MW4TEXT, sbtext, sbtext.Capacity);
            lbUserNames.Items.Add(sbtext.ToString());

        }
       

    }
}

Here is a picture of the program running. Note, that I can send text fine to said window.



I have the handle of the window I want to extract text from. But, like I said it isn't working. Any ideas?
