Example of a typical host class

class Host : Component, IWndProcProvider //Note derivation from component is not mandatory

{

    ExtNativeWindow _nw;

    public Host()

    {

        _nw=new ExtNativeWindow(this);

    }

    void IWndProcProvider.WndProc(ref Message m, ExtNativeWindow defWndProcProvider)

    {

        //Do WndProc loop here... and call the defWndProcProvider.DefWndProc(ref m) for all unhandled messages

    }

}

class Host : Component, IWndProcProvider //Note derivation from component is not mandatory

{

    ExtNativeWindow _nw;

    public Host()

    {

        _nw=new ExtNativeWindow(this);

    }

    void IWndProcProvider.WndProc(ref Message m, ExtNativeWindow defWndProcProvider)

    {

        //Do WndProc loop here... and call the defWndProcProvider.DefWndProc(ref m) for all unhandled messages

    }
