Workbook.BeforeClose 事件 (2007 系統)
更新:2007 年 11 月
在活頁簿關閉前發生。如果活頁簿已變更,則這個事件會在詢問使用者儲存變更前發生。
命名空間: Microsoft.Office.Tools.Excel
組件: Microsoft.Office.Tools.Excel.v9.0 (在 Microsoft.Office.Tools.Excel.v9.0.dll 中)
語法
Public Event BeforeClose As WorkbookEvents_BeforeCloseEventHandler
Dim instance As Workbook
Dim handler As WorkbookEvents_BeforeCloseEventHandler
AddHandler instance.BeforeClose, handler
public event WorkbookEvents_BeforeCloseEventHandler BeforeClose
範例
下列程式碼範例會示範 BeforeClose 事件的處理常式。如果活頁簿自上次儲存後已變更,下列程式碼便會提示使用者儲存變更、不儲存並更或取消關閉操作。如果使用者不儲存變更,則活頁簿的 Saved 屬性會設為 true,因此在執行關閉動作時,Microsoft Office Excel 不會提示使用者儲存活頁簿。如果使用者取消關閉動作,則 WorkbookEvents_BeforeCloseEventHandler 事件處理常式的 Cancel 參數設為 true,因此 Microsoft Office Excel 不會關閉活頁簿。
這是示範文件層級自訂的範例。
Sub ThisWorkbook_BeforeClose(ByRef Cancel As Boolean) _
Handles Me.BeforeClose
If Not Me.Saved Then
Dim result As DialogResult = _
MessageBox.Show("Do you want to save the " & _
"changes you made to " & Me.Name & "?", _
"Example", MessageBoxButtons.YesNoCancel)
Select Case result
Case DialogResult.Yes
Me.Save()
Case DialogResult.Cancel
Cancel = True
' The following code ensures that the default Save File
' dialog is not displayed.
Case DialogResult.No
Me.Saved = True
End Select
End If
End Sub
private void WorkbookBeforeClose()
{
this.BeforeClose +=
new Excel.WorkbookEvents_BeforeCloseEventHandler(
ThisWorkbook_BeforeClose);
}
void ThisWorkbook_BeforeClose(ref bool Cancel)
{
if (!this.Saved)
{
DialogResult result = MessageBox.Show("Do you want to save the " +
"changes you made to " + this.Name + "?", "Example",
MessageBoxButtons.YesNoCancel);
switch (result)
{
case DialogResult.Yes:
this.Save();
break;
case DialogResult.Cancel:
Cancel = true;
break;
// The following code ensures that the default Save File
// dialog is not displayed.
case DialogResult.No:
this.Saved = true;
break;
}
}
}
