Send to tray on Close

Question

How can I send the window minimized to tray when on click close button? Also how to show icon in tray when application start?

Answer 1

There is nothing that comes embedded with WPF. From implementations that you can find on the net, there is an "easy" one, that uses WinForms:

But I like this one more (can be used for balloon tips too)

Answer 2

WinForm:

One approach is to set the Cancel property of FormClosingEventArgs in the FormClosing event of your window and instead minimize to tray. For minimizing to tray, see this article:

Window Tray Minimizer

Code Project has more articles on the topic, but the one I linked worked for me.

WPF:

I've never had to do this in WPF but did poke around for a solution. I found this:

Creating a Tray Icon for a WPF Application

You'll find the code works but I recommend testing. The article addresses opening an application minimized to the tray.

You might also find this sample on MSDN useful:

In winforms you can overload WndProc and watch for the WM_CLOSE message.

    WM_CLOSE = 0x0010

    protected override void WndProc(ref Message m)
    {
      if(m.Msg == WM_CLOSE)
      {
        this.Hide();
        trayIcon.Show();
      }

    }
