How do I open my closed form through the notifyicon in the taskbar?

Question

Currently I am developing a windows form application in c# that has several forms.

I am running a background form that operates the notifyicon property that allows the icon to appear in the taskbar.

When I launch the program, it will launch a loginForm, after which logging in it will go into a mainForm. After closing the mainForm, the application does not close yet, which in this case works like Windows Live Messenger.

How do I make my program in a way that after I the mainForm, through double clicking it will bring the form back up? (Like how MSN works.)

Or is it a better solution for me to close the whole application when I press the X button in the title bar. Which brings up another problem for me as I cant seem to exit the application when I close other forms other than the main form.

Probably you have NotifyIcon on your main form. Subscribe on the DoubleClick event of this control and change state of your main form in the handler:

    private void notifyIcon1_DoubleClick(object sender, EventArgs e)
    {
        this.Show();
        this.Visible = true;
        this.WindowState = FormWindowState.Normal;
    }
