Hi,

I'm added a System tray icon to my C# application and I'm wanting to change the minimize function so that when the minimize button in clicked, only the System Tray icon is left, and the usual tab shown in the task bar is not shown until the application is restored.  How do I do this?

Many Thanks

Here is a simple way to do it (althought you could easily expand on this implementation, keeping track of the previous window state to avoid always calling the ShowInTaskbar setter method, for example).

In your form class place the following code:

  protected override void OnSizeChanged(System.EventArgs e)
  {
    if(this.WindowState==System.Windows.Forms.FormWindowState.Minimized)
      this.ShowInTaskbar = false;
    else
      this.ShowInTaskbar = true;
    base.OnSizeChanged(e);
  }

This will hide your form on the taskbar when it gets minimized.  To restore your form call the code, "this.WindowState = System.Windows.Forms.FormWindowState.Normal".  The taskbar tab will be visible again.
