c# - 現在実行中のアプリケーションを削除せずにマウスフックを設定しますか？

Question

実行時にGUIを開くプログラムがあります。次に、dllimportsを使用してマウスフックを設定したいのですが、それを機能させるには、この同じクラスで新しいApplication.Run（）を呼び出す必要があります。ただし、残念ながら、これにより元のGUIが削除されます。元のメッセージループでマウスフックを実行する方法はありますか？私はここで少し迷っています。

コードのいくつかの重要な部分は次のとおりです。

//main

public static GUI GUIref;

static void Main()
{
     Application.EnableVisualStyles();
     Application.SetCompatibleTextRenderingDefault(false);
     Application.Run(GUIref = new GUI());
}

。

//Initializing constructor    

    public partial class GUI : Form
    {
        public GUI()
        {
            InitializeComponent();
            keyReceive kR = new keyReceive();
            mouseReceive mR = new mouseReceive();
        }
    }

。

//mousehook class:

    public class mouseReceive : Form
    {
        private static LowLevelMouseProc _proc = HookCallback;
        private static IntPtr _hookID = IntPtr.Zero;
        public mouseReceive()
        {
            _hookID = SetHook(_proc);
            //***This is where I have been putting Application.Run() to make the mousehook work***
            UnhookWindowsHookEx(_hookID);
        }

        private static IntPtr SetHook(LowLevelMouseProc proc)
        {
            using (Process curProcess = Process.GetCurrentProcess())
            using (ProcessModule curModule = curProcess.MainModule)
            {
                return SetWindowsHookEx(WH_MOUSE_LL, proc,
                    GetModuleHandle(curModule.ModuleName), 0);
            }
        }

        private delegate IntPtr LowLevelMouseProc(int nCode, IntPtr wParam, IntPtr lParam);

        private static IntPtr HookCallback(
            int nCode, IntPtr wParam, IntPtr lParam)
        {

            if (nCode >= 0 &&
                MouseMessages.WM_LBUTTONDOWN == (MouseMessages)wParam)
            {
                MessageBox.Show("");

            }
            return CallNextHookEx(_hookID, nCode, wParam, lParam);
        }

        private const int WH_MOUSE_LL = 14;

        private enum MouseMessages
        {
            WM_LBUTTONDOWN = 0x0201
        }


        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern IntPtr SetWindowsHookEx(int idHook,
            LowLevelMouseProc lpfn, IntPtr hMod, uint dwThreadId);

        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
