插入公式后的宏延迟问题-Excel

标签： excel vba excel-formula latency

我在Excel中有一个中央数据库，该数据库使用在Column B中输入的特定值，并基于该值隐藏/取消隐藏其他相关的Columns。在我输入单独的公式将不同的值复制到各自的sheets之前，这一直很好。

例如如果在A中输入了Column B，则应该Columns D:E。然后，单独的formula会将row复制到包含所有sheet的单独A's中。

问题在于此宏现在需要很长时间才能执行。我禁用了公式以使其手动运行，但这无济于事。这是隐藏/取消隐藏列的宏的示例。

Private Sub Worksheet_Change(ByVal Target As Range)

    If Not Intersect(Target, Range("B:B")) Is Nothing Then
        On Error GoTo safe_exit
        Application.EnableEvents = False
        Dim t As Range
        For Each t In Intersect(Target, Range("B:B"))
            Select Case (t.Value)
                Case "A"

                    Columns("BQ").EntireColumn.Hidden = True 
                    'do nothing
            End Select
        Next t
        ActiveWindow.Zoom = 100 '<<<
    End If

safe_exit:
    Application.EnableEvents = True

End Sub

这是公式：

=IF(IFERROR(INDEX('XXXXX'!B$5:B$9963,MATCH($A5,'XXXXX'!$A$5:$A$9963,0)),"")="","",INDEX('XXXXX'!B$5:B$9963,MATCH($A5,'XXXXX'!$A$5:$A$9963,0)))

数据库包含大约3000行。文件大小约为7-8MB。我删除了所有公式，但存在相同的延迟。我删除了2000行数据，这使其速度更快。但这似乎并没有很大的作用？

该文件通过OneDrive与许多使用它的实时用户共享。此后，用户提到他根本无法打开文件。打开时崩溃。可能是巧合，链接断开导致损坏吗？

答案 0 :(得分：1)

请注意，您可以将代码减少到一个Intersect(Target, Range("B:B"))，然后踢出循环并使用Match函数。这样，您将只隐藏该列一次，而不是每次 都会在受影响的范围内出现一个值A。

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)

    Dim AffectedRange As Range
    Set AffectedRange = Intersect(Target, Range("B:B")) 'intersect olny once and set into variable for re-use

    If Not AffectedRange Is Nothing Then
        On Error GoTo safe_exit
        Application.EnableEvents = False

        Dim FoundAt As Long
        On Error Resume Next
        FoundAt = Application.WorksheetFunction.Match("A", AffectedRange, False)
        On Error GoTo 0

        If FoundAt <> 0 Then
            Columns("B:BQ").EntireColumn.Hidden = False
            Columns("H:AD").EntireColumn.Hidden = True
            Columns("AF:BL").EntireColumn.Hidden = True
            Columns("BQ").EntireColumn.Hidden = True
        End If

        ActiveWindow.Zoom = 100 '<<<
    End If

safe_exit:
    Application.EnableEvents = True
End Sub
