插入公式后的宏延迟问题 - Excel

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了插入公式后的宏延迟问题 - Excel相关的知识，希望对你有一定的参考价值。

我在Excel有一个中央数据库，它使用输入Column B的特定值，并根据此值隐藏/取消隐藏其他相关的Columns。这工作正常，直到我放入单独的公式，将不同的值复制到他们各自的sheets。

例如。如果A进入Column B它应该Columns D:E。然后一个单独的formula将row复制到一个单独的sheet，其中包含所有的A's。

问题是这个宏现在需要很长时间才能完成。我已禁用公式以使它们手动运行但它没有帮助。以下是隐藏/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("B:BQ").EntireColumn.Hidden = False
                    Columns("H:AD").EntireColumn.Hidden = True
                    Columns("AF:BL").EntireColumn.Hidden = True
                    Columns("BQ").EntireColumn.Hidden = True
                Case "B"
                    Columns("B:BQ").EntireColumn.Hidden = False

                 Case "V"

                    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)))

该数据库包含大约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，这使得它更快。但看起来不是很大的差别呢？

该文件通过OneDrive共享，许多用户实时使用它。用户后来提到他根本无法打开文件。它在打开时崩溃了。这可能是一个巧合，一个破碎的链接导致腐败？

答案

请注意，您可以将代码减少到只有一个Intersect(Target, Range("B:B"))并启动循环并使用Match函数。这样，您只会隐藏列一次，而不是每次在受影响的范围内出现值A时。

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
