Description:

Auto Saver is an application that will send a user defined key stroke to a designated application through the user32.dll api based on a timer,
the numlock key is used to suspend sending of the key sequence. If either the numlock key is off, or the user defined application is not running,the application will do nothing.

The application was designed to introduce a autosave feature to EA’s spore video game, and thus its name was derived.

The key sequences used follow this format.

Code used to make sure desired process is running, set the process to forground, and send key sequence

        static public IntPtr getWin(string process_name)
        {
            Process[] processes = Process.GetProcessesByName(process_name);

            {
                win_handle = p.MainWindowHandle;
            }
            return win_handle;
        }

        // Activate an application window.
        [DllImport("USER32.DLL")]
        public static extern bool SetForegroundWindow(IntPtr hWnd);
         

        private void saver_fire(object sender, EventArgs e)
        {

            IntPtr applicationHandle = getWin(processName);

            // Verify that application is a running process.
            if (applicationHandle != IntPtr.Zero && Console.NumberLock)
            {
                // Make application the foreground application and send it 
                // the keys you want.
                SetForegroundWindow(applicationHandle);
                string keySeq = Properties.Settings.Default.txtSequence.ToString();
                SendKeys.SendWait(keySeq);
