The following code example creates a ToolBar and three ToolBarButton controls. The toolbar buttons are assigned to the button collection, the collection is assigned to the toolbar, and the toolbar is added to the form. On the ButtonClick event of the toolbar, the Button property of the ToolBarButtonClickEventArgs is evaluated, and the appropriate dialog box opened. This code requires that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have been created.

Public Sub InitializeMyToolBar()
    ' Create and initialize the ToolBar and ToolBarButton controls.
    Dim toolBar1 As New ToolBar()
    Dim toolBarButton1 As New ToolBarButton()
    Dim toolBarButton2 As New ToolBarButton()
    Dim toolBarButton3 As New ToolBarButton()

    ' Set the Text properties of the ToolBarButton controls.
    toolBarButton1.Text = "Open"
    toolBarButton2.Text = "Save"
    toolBarButton3.Text = "Print"

    ' Add the ToolBarButton controls to the ToolBar.

    ' Add the event-handler delegate.
    AddHandler toolBar1.ButtonClick, AddressOf Me.toolBar1_ButtonClick

    ' Add the ToolBar to the Form.
End Sub    

Private Sub toolBar1_ButtonClick(ByVal sender As Object, _
ByVal e As ToolBarButtonClickEventArgs)

    ' Evaluate the Button property to determine which button was clicked.
    Select Case toolBar1.Buttons.IndexOf(e.Button)
        Case 0
            ' Insert code to open the file.
        Case 1
            ' Insert code to save the file.
        Case 2
            ' Insert code to print the file.
    End Select
End Sub
