模擬鼠標(biāo)發(fā)送點(diǎn)擊
怎么樣能模擬鼠標(biāo)快速點(diǎn)擊 

                    PostMessage(ip, WM_LBUTTONDOWN, 1, lparam);

                    Thread.Sleep(100);

                    PostMessage(ip, WM_LBUTTONUP, 1, lparam);

PostMessage中間不加Thread的話 會失常  有沒有更快點(diǎn)擊的辦法
------解決方案--------------------
    [DllImport("User32.dll", EntryPoint = "SendMessage")]
        private static extern int SendMessage(
        IntPtr hWnd,
        int Msg,
        int wParam,
        int lParam
        );
        private void button1_Click(object sender, EventArgs e)
        {

            SendMessage((IntPtr)comboBox2.Handle, 0x0201, 0, 0);
            SendMessage((IntPtr)comboBox2.Handle, 0x0202, 0, 0);

        }

其中API參數(shù)的含義為：

        //按下鼠標(biāo)左鍵
        public static int WM_LBUTTONDOWN = 0x0201;
        //釋放鼠標(biāo)左鍵
        public static int WM_LBUTTONUP = 0x0202;


這個中間不用延時，因?yàn)镾endMessage是等待消息返回再執(zhí)行下一個，而PostMessage不等待消息返回就執(zhí)行下一個
