A Delegate type used to add an event handler for the WorkbookBeforeClose event. The WorkbookBeforeClose event occurs immediately before any open workbook closes.

Assembly: Microsoft.Office.Interop.Excel (in

Sub Sub1(Wb As Workbook, _
	Cancel As Boolean)
End Sub
Dim appEvents_WorkbookBeforeCloseEventHandler1 As New AppEvents_WorkbookBeforeCloseEventHandler(AddressOf Sub1)

	<InAttribute()> ByVal Wb As Workbook, _
	<InAttribute(), OutAttribute()> ByRef Cancel As Boolean _

	/*in*/Workbook Wb, 
	/*in*/boolean Cancel
In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

False when the event occurs. If the event procedure sets this argument to True, the workbook doesn't close when the procedure is finished.
