Winamp Control

Hej,
jeg har lavet et Winamp Control ud fra en guide jeg fandt et eller andet sted (kan ikke huske hvor).
Desværre virker det ikke :(

Jeg får en exception (den i koden nedenunder) fordi den ikke kan finde winduet.. "Winamp v1.x"

Men hvad hedder vinduet så??

Her er koden:
-----------------------------
        public Control()
        {
            // Try to find a Winamp window.
            WINDOW_HANDLER = FindWindow("Winamp v1.x",null);
   
            if(WINDOW_HANDLER == 0)
            {
                // Throw exception if we can not find a Winamp window.
                throw new System.Exception("Could not find a Winamp window!");
            }
        }

        /// <summary>
        ///    The value returned is a 32-bit value representing the window.
        ///    If no window is found, the return value will be 0 and we will
        ///    throw an exception. Since the method mentioned is a native API
        ///    method in the file user32.dll, we somehow need to declare a method
        ///    as having an implementation from a DLL export. This is where the
        ///    DllImport-attribute and the extern keyword is used.
        /// </summary>
        [System.Runtime.InteropServices.DllImport("user32.dll",EntryPoint="SendMessage")]
        private static extern int SendMessage(int _WindowHandler, int _WM_USER, int _data, int _id);

        /// <summary>
        ///    The first argument is of course the file, in which we expect to
        ///    find the method. The second argument, the entrypoint, is the actual
        ///    name of the method. This argument only has to be passed if we want
        ///    to name our extern C# method to something else. This is not the case,
        ///    and the argument is shown mostly for convinience. Note that extern
        ///    methods have to be declared as static and we must use the keyword
        ///    extern.
        /// </summary>
        [System.Runtime.InteropServices.DllImport("user32.dll",EntryPoint="FindWindow")]
        private static extern int FindWindow(string _ClassName, string _WindowName);
