There's a thread in the newsgroups where someone is trying to show a Notification before his app does some long-running process. Here's an example of how it's done.

1. Create a WM 5.0 Windows app, then add a reference to 'Microsoft.WindowsCE.Forms'.
2. Add a single Button to the Form and name it 'workButton'
3. Add this to the top of the code page:
   
   

   using System.Threading;
   using Microsoft.WindowsCE.Forms;
   

4. Replace the entire non-designer Form class code with this:
   
   

   public partial class Form1 : Form
   {
     public Form1()
     {
       InitializeComponent();
       workButton.Click += new System.EventHandler(workButton_Click);
     }
   
     delegate void EventDelegate();
   
     Notification m_workNotify = new Notification();
     Control m_invoker = new Control();
     EventDelegate m_workCompleteDelegate;
   
     private void workButton_Click(object sender, EventArgs e)
     {
       // disable the button so it can't be clicked again until work is done
       workButton.Enabled = false;
       m_workCompleteDelegate = new EventDelegate(OnWorkComplete);
   
       Thread workThread = new Thread(new ThreadStart(WorkProc));
       m_workNotify.Text = "I'm doing important stuff";
       m_workNotify.Caption = "Please wait...";
       m_workNotify.InitialDuration = 5;
   
       m_workNotify.Visible = true;
   
       workThread.Start();
     }
   
     void OnWorkComplete()
     {
       // re-enable the button
       workButton.Enabled = true;
     }
   
     void WorkProc()
     {
       // simulate working
       Thread.Sleep(20000);
       m_invoker.Invoke(m_workCompleteDelegate);
     }
   }
