The System.Windows.Forms.Button class is the .NET implementation of a button control. When the user clicks the button with the stylus, a Click event is raised. You can handle this event by implementing a System.EventHandler delegate. The code that follows is an implementation of the EventHandler that displays the current time.
C# Private void button_Click(object sender, System.EventArgs e) { MessageBox.Show(DateTime.Now.ToShortTimeString(), "The Current Time Is", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1); } VB Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MessageBox.Show(DateTime.Now.ToShortTimeString(), "The Current Time Is", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1) End Sub
Figure 3.6 shows the GiveEmTime.exe running on the Pocket PC emulator. The button labeled What is the Time has been clicked, and the current time is being displayed in the dialog box.
