VBA，当您手动更改单元格或单元格值范围时，可以触发事件驱动的编程。更改事件可能使事情变得容易，但是您可以非常快速地结束充满格式的页面。有两种事件。

  • 工作表事件
  • 工作簿活动

工作表事件

当工作表中发生更改时，将触发工作表事件。通过在工作表选项卡上单击鼠标右键，然后选择“查看代码”，然后粘贴代码，可以创建该代码。

用户可以选择这些工作表中的每个工作表，然后从下拉列表中选择“ WorkSheet”以获取所有受支持的工作表事件的列表。

输入框演示

以下是用户可以添加的受支持的工作表事件。

Private Sub Worksheet_Activate() 
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)    
Private Sub Worksheet_BeforeRightClick(ByVal Target As Range, Cancel As Boolean) 
Private Sub Worksheet_Calculate() 
Private Sub Worksheet_Change(ByVal Target As Range) 
Private Sub Worksheet_Deactivate() 
Private Sub Worksheet_FollowHyperlink(ByVal Target As Hyperlink) 
Private Sub Worksheet_SelectionChange(ByVal Target As Range)

例

让我们说，我们只需要在双击之前显示一条消息即可。

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
   MsgBox "Before Double Click"
End Sub

输出

双击任何单元格时，将向用户显示该消息框，如以下屏幕截图所示。

工作簿活动

整体上更改工作簿时，将触发工作簿事件。我们可以通过选择“ ThisWorkbook”并从下拉菜单中选择“ workbook”来添加工作簿事件的代码，如以下屏幕截图所示。立即将Workbook_open子过程显示给用户，如以下屏幕快照所示。

输入框演示

以下是用户可以添加的受支持的Workbook事件。

Private Sub Workbook_AddinUninstall() 
Private Sub Workbook_BeforeClose(Cancel As Boolean) 
Private Sub Workbook_BeforePrint(Cancel As Boolean) 
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean) 
Private Sub Workbook_Deactivate() 
Private Sub Workbook_NewSheet(ByVal Sh As Object) 
Private Sub Workbook_Open() 
Private Sub Workbook_SheetActivate(ByVal Sh As Object) 
Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, ByVal Target As Range, Cancel As Boolean) 
Private Sub Workbook_SheetBeforeRightClick(ByVal Sh As Object, ByVal Target As Range, Cancel As Boolean) 
Private Sub Workbook_SheetCalculate(ByVal Sh As Object) 
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range) 
Private Sub Workbook_SheetDeactivate(ByVal Sh As Object) 
Private Sub Workbook_SheetFollowHyperlink(ByVal Sh As Object, ByVal Target As Hyperlink) 
Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range) 
Private Sub Workbook_WindowActivate(ByVal Wn As Window) 
Private Sub Workbook_WindowDeactivate(ByVal Wn As Window) 
Private Sub Workbook_WindowResize(ByVal Wn As Window)

例

让我们说，只要创建新表，我们只需要向用户显示一条消息，即成功创建了新表。

Private Sub Workbook_NewSheet(ByVal Sh As Object)
   MsgBox "New Sheet Created Successfully"
End Sub

输出

创建新的Excel工作表后，将向用户显示一条消息，如以下屏幕截图所示。
