Answer 1

To Create a system Tray application in Windows-CE, put some code like:

CSystemTray m_TrayIcon;   // Member variable of some class

... 
// in some member function maybe...

m_TrayIcon.Create(pParentWnd, WM_MY_NOTIFY, "Click here", 
                  hIcon, nTrayIconID);

Eg. For a non-MFC tray icon, do the following:

Collapse
CSystemTray m_TrayIcon;   // Member variable of some class

... 
// in some member function maybe...

m_TrayIcon.Create(hInstance, NULL, WM_MY_NOTIFY, 
                  "Click here", hIcon, nID);

// Send all menu messages to hMyMainWindow

m_TrayIcon.SetTargetWnd(hMyMainWindow);

To create a system tray application in Windows XP or Windows 7/Vista, put some code like this in your project:

private void Form1_Resize(object sender, System.EventArgs e)
{
   if (FormWindowState.Minimized == WindowState)
      Hide();
}

and this to handle the system tray click

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

It's not implemented in the CF, but the NotifyIcon class is what you're after. The SDF does implement it. It would be used something like this:

m_notifyIcon = new NotifyIcon();
m_notifyIcon.Icon = this.Icon;
m_notifyIcon.Visible = true;
m_notifyIcon.Click += new EventHandler(m_notifyIcon_Click);
m_notifyIcon.DoubleClick += new EventHandler(m_notifyIcon_DoubleClick);

EDIT

If you want to implement this yourself, the place to start is with the Shell_NotifyIcon API. You'll want to pass it the handle to a MessageWindow class and handle the WM_NOTIFY messages.
