excel - 如何在 SelectionChange 之前触发 EXCEL 事件 BeforeDoubleClick？

Question

我要火灾 BeforeDoubleClick 事件 之前 EXCEL 工作表的 SelectionChange 事件。

顺序通常是相反的:选择更改事件 第一次，后来 BeforeDoubleClick-事件 .

我的目标是要么 运行 MyDoubleClickCode，如果有双击，或 如果不是，请运行 MyChangeSelectionCode。

问题取决于事件触发的顺序!

我的 最佳 解决方案来了:

    ' This Event is **MAYBE** fired secondly and runs the MyDoubleClickCode
    Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
        dblFlag = true
        ...
        MyDoubleClickCode
        ...
    End Sub

    ' This event is always fired AND runs first
    Private Sub Worksheet_SelectionChange(ByVal Target As Range)
        dblFlag = false
        alertTime = Now + TimeValue("00:00:01")
        Application.OnTime alertTime, "MyChangeSelectionSub"
    End Sub

    ' Userdefined subroutine which will run one second after an event ( doubleclick or not).
    public sub MyChangeSelectionSub() 
        If NOT dblFlag then
            ...
            MyChangeSelectionCode
            ...
        End if
    End Sub

我用 准时在我的 SelectionChange-event 中调用 MyChangeSelectionSub 一秒后触发选择更改。这给了处理 BeforeDoubleClick 事件和执行 MyDoubleClickCode 的时间 - 如果单元格也被双击。达到了我想要的逻辑，但是...

……当然很笨拙，不满意:我要等一秒在 MyChangeSelectionSub 开始之前，而不是 就在 之后已经处理了 BeforeDoubleClick 事件。

Maybee有一种逻辑 让这发生？任何想法？

编辑 :我已经编辑了代码示例，以便更清楚地了解我的问题!而且我现在知道我无法更改事件的顺序，但是如何不使用 onTime 解决方案？

这对我“有效”，但似乎不稳定。 OnTime 方法的计时可能会导致我们可能需要接受的执行中的“不舒服的暂停”。 (或改进。)

'worksheet (Name) is "Sheet17" in the VBA Properties window
'worksheet Name is "Sheet1" as shown in the worksheet tab in the application Excel

Private double_click_detected As Boolean
Private SelectionChange_target As Range

' This Event is **MAYBE** fired secondly and runs the MyDoubleClickCode
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
  double_click_detected = True
  '...
  MsgBox "MyDoubleClickCode"
  '...
End Sub

' This event is always fired AND runs first
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Set SelectionChange_target = Target
    alertTime = Now + TimeValue("00:00:01")
    Application.OnTime alertTime, "Sheet17.MyChangeSelectionSub"
End Sub

' Userdefined subroutine which will run one second after an event ( doubleclick or not).
Public Sub MyChangeSelectionSub()
  If Not double_click_detected Then
    '...
    MsgBox "MyChangeSelectionCode"
    '...
  End If
End Sub
