Hi Tyrone,

You'll probably have to write and install something on the client. Javascript, and by extension pretty much anything on the client side, can't poke around on a client computer for information, for obvious security reasons. Research Activex objects; I've never used them, so I can't give you more help than that, but it's where you'll probably want to start.

public partial class MainFrm : Form
    {
        public MainFrm()
        {
            InitializeComponent();
            btnOK.Click += new EventHandler(btnOK_Click); Resize += new EventHandler(MainFrm_Resize);
            TB_Icon.MouseDoubleClick += new MouseEventHandler(TB_Icon_MouseDoubleClick);
            ContMenuStrip.Click += new EventHandler(ContMenuStrip_Click);
        }

        void btnOK_Click(object sender, EventArgs e)
        {
            WindowState = FormWindowState.Minimized;
        }

        void MainFrm_Resize(object sender, EventArgs e)
        {
            if (WindowState == FormWindowState.Minimized)
                Hide();
        }

        void TB_Icon_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            Show();
            WindowState = FormWindowState.Normal;
        }

        void ContMenuStrip_Click(object sender, EventArgs e)
        {
            Show();
            WindowState = FormWindowState.Normal;
        }
    }

Now, keep in mind that after the user completes the MainFrame form (clicks the "OK" button), a loop is constantly running

public partial class MainFrm : Form
    {
        Timer MyReminder = new Timer();

        public MainFrm()
        {

            TB_Icon.MouseDoubleClick += new MouseEventHandler(TB_Icon_MouseDoubleClick);
            ContMenuStrip.Click += new EventHandler(ContMenuStrip_Click);
            MyReminder.Interval = 2000; // 2 seconds
            MyReminder.Tick += new EventHandler(MyReminder_Tick);
        }

        void MyReminder_Tick(object sender, EventArgs e)
        {
            // Reminder stuff goes here
            Console.WriteLine("You have been reminded at " + DateTime.Now); 
        }

            else
            {
                MyReminder.Stop();
            }
        } 
        void TB_Icon_MouseDoubleClick(object sender, MouseEventArgs e)

            WindowState = FormWindowState.Normal;
