关闭后反复打开Excel工作簿

Question

我使用了Application.ontime（）方法来调度一些宏，在关闭工作簿后，它会一次又一次地打开。 为解决此问题，我在工作簿上设置了另一个事件-BeforeClosed。 现在它显示运行时错误1004：'Object'_Application的方法'OnTime'失败。即使从Web上获得帮助上下文，我也无法理解为什么会发生这种情况。 给出以下代码。

Private Sub Workbook_Open()

starttime = Now + TimeValue("00:02:00")

Application.OnTime EarliestTime:=starttime, Procedure:="startapp", schedule:=True

rtime = TimeValue("14:30:00")

Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder",  Schedule:=True   

Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder_out",Schedule:=True  

Application.OnTime EarliestTime:=rtime, Procedure:="SendReminderFromProxy",Schedule:=True  


End Sub


Private Sub Workbook_BeforeClose(Cancel As Boolean)

MsgBox "Dear" & " " & Environ("USERNAME") & ", " & "Please do not forget to save before closing."

starttime = Now + TimeValue("00:02:00")

Application.OnTime EarliestTime:=starttime, Procedure:="startapp", Schedule:=False

rtime = TimeValue("14:30:00")

Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder", Schedule:=False       

Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder_out", Schedule:=False

Application.OnTime EarliestTime:=rtime, Procedure:="SendReminderFromProxy", Schedule:=False

End Sub

Answer 1

取消OnTime ，您需要使用与创建时相同的参数值（第三个参数除外）。

这意味着取消时您不能经过其他时间。

Dim starttime '<<< store the time values for later use...
Dim rtime

Private Sub Workbook_Open()

    starttime = Now + TimeValue("00:02:00")

    Application.OnTime EarliestTime:=starttime, Procedure:="startapp", schedule:=True

    rtime = TimeValue("14:30:00")

    Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder",  Schedule:=True   

    Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder_out",Schedule:=True  

    Application.OnTime EarliestTime:=rtime, Procedure:="SendReminderFromProxy",Schedule:=True  


End Sub


Private Sub Workbook_BeforeClose(Cancel As Boolean)

    MsgBox "Dear" & " " & Environ("USERNAME") & ", " & "Please do not forget to save before closing."

    'use the global variable here
    On Error Resume Next '<< prevent error if no schedule is set
                         '   or if already triggered
    Application.OnTime EarliestTime:=starttime, Procedure:="startapp", Schedule:=False
    Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder", Schedule:=False       
    Application.OnTime EarliestTime:=rtime, Procedure:="sendreminder_out", Schedule:=False
    Application.OnTime EarliestTime:=rtime, Procedure:="SendReminderFromProxy", Schedule:=False
    On Error Goto 0

End Sub
