Private Sub ThisDocument_BeforePrint(ByVal sender As Object, ByVal e As System. _
    ComponentModel.CancelEventArgs)
    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    If System.Windows.Forms.MessageBox.Show("Do you want to print the document?", "BeforePrint", _
