Private Sub menuItemHelpAbout_Click(sender As Object, _ e As EventArgs) Handles menuItemHelpAbout.Click ' Create and display a modless about dialog box. Dim about As New AboutDialog() about.Show() ' Draw a blue square on the form. ' NOTE: This is not a persistent object, it will no longer be ' visible after the next call to OnPaint. To make it persistent, ' override the OnPaint method and draw the square there Dim g As Graphics = about.CreateGraphics() g.FillRectangle(Brushes.Blue, 10, 10, 50, 50) End Sub
