SendKeys for .NETCF

Because System.Windows.Forms SendKeys does not support in .NETCF,
So I have to implement it thru APIs,

here is the solutions: SendInput, keybd_event, PostKeybdMessage and SendMessage

        [DllImport("coredll.dll", SetLastError = true)]

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

        static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);



        [DllImport("coredll", SetLastError = true)]

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

        public static extern IntPtr FindWindow(string _ClassName, string _WindowName);



        [DllImport("coredll", SetLastError = true)]

        //[DllImport("user32.dll")]

        private static extern bool SetForegroundWindow(IntPtr hWnd);



        public static void SendIt()

        {

            IntPtr ip = FindWindow("notepad", null);





            SetForegroundWindow(ip);



            const int KEYEVENTF_KEYUP = 0x2;



            const int KEYEVENTF_KEYDOWN = 0x0;



            byte VK_TAB = 0x0D;



            keybd_event(VK_TAB, 0, KEYEVENTF_KEYDOWN, 0);

            keybd_event(VK_TAB, 0, KEYEVENTF_KEYUP, 0);

       }
