Beispiel

Im folgenden Codebeispiel wird das Behandeln des Click-Ereignisses veranschaulicht. Dabei wird davon ausgegangen, dass Sie den Code in ein Formular eingefügt haben, das ein NotifyIcon-Objekt mit der Bezeichnung NotifyIcon1 enthält.

' Initalize the NofifyIcon object's shortcut menu.
Private Sub InitializeContextMenu()
    Dim menuList() As MenuItem = New MenuItem() _
                {New MenuItem("Sign In"), New MenuItem("Get Help"), _
                New MenuItem("Open")}
    Dim clickMenu As New ContextMenu(menuList)
    NotifyIcon1.ContextMenu = clickMenu
End Sub


' When user clicks the left mouse button display the shortcut menu.  
' Use the SystemInformation.PrimaryMonitorMaximizedWindowSize property
' to place the menu at the lower corner of the screen.
Private Sub NotifyIcon1_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles NotifyIcon1.Click
