这个事件是多余的吗?
程序代码:
[local]1[/local] Private Sub Form_Load() dispaly.FontSize = 20 End Sub Private Sub dispaly_Change() If underon.Value = 1 Then dispaly.FontUnderline = True ElseIf Italic.Value = 1 Then dispaly.FontItalic = True End If End Sub Private Sub Italic_Click() If Italic.Value = 1 Then dispaly.FontItalic = True Else dispaly.FontItalic = False End If End Sub Private Sub underon_Click() If underon.Value = 1 Then dispaly.FontUnderline = True Else dispaly.FontUnderline = False End If End Sub 感觉第二段dispaly_Change()事件完全是多余的,除掉之后程序还是能运行,谁能告诉我它干什么用的吗?
