BeforeSave Event [Excel 2003 VBA Language Reference]
Occurs before the workbook is saved.
Private Sub Workbook_BeforeSave(ByVal SaveAsUi As Boolean, Cancel As Boolean)
SaveAsUi True if the Save As dialog box will be displayed.
Cancel False when the event occurs. If the event procedure sets this argument to True, the workbook isn't saved when the procedure is finished.
This example prompts the user for a yes or no response before saving the workbook.
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, _ Cancel as Boolean) a = MsgBox("Do you really want to save the workbook?", vbYesNo) If a = vbNo Then Cancel = True End Sub
