问题描述

以下代码不起作用。我的 VLOOKUP 函数出现 2042 错误,但是无论我做什么我都无法解决它。我一直在使用 if ISERROR ,但它仍然无法正确捕获它,从而损害了我的整个宏。如果我运行本地窗口,您可以看到要搜索的值存储在数组“arr”中,如果在“目标”范围内未找到,即使后续条目也返回 2042。

Sub test()
ThisWorkbook.Activate

Worksheets.add

Worksheets("Test4").Range("A1:T110").copy Destination:=ActiveSheet.Range("A1")

With ActiveSheet

    Dim Search_Array As Variant
    Search_Array = Range("C2", Range("C1").End(xlDown)) 'use this array to loop through the value to search for


    Dim Target_MatchValue As Integer
    Dim Target_Range As Range
    Dim arr As Variant
    Dim counter As Integer
    Dim n As Integer



    counter = 0
    n = 0
    Target_MatchValue = 0

    For counter = LBound(Search_Array) To UBound(Search_Array)
        Target_MatchValue = 0

        Target_MatchValue = Application.Match(Search_Array(counter, 1), .Range("H2:H200"), 0) - 1 
        Set Target_Range = .Range(.Cells(2 + n, 8), .Cells(1000, 9))           

        arr = Application.VLookup(Search_Array(counter, 1), Target_Range, 2, False)

            If IsError(arr) Then
                .Range(Cells(1 + counter, 6), Cells(1 + counter, 6)).value = "N/A"
            Else
                .Range(Cells(1 + counter, 6), Cells(1 + counter, 6)).value = arr 'Return the value of the array in this cell
            End If



        Target_Range.Select

        If Target_MatchValue = 0 Then

            n = n + 1

            ElseIf Target_MatchValue > 0 Then
            n = n + Target_MatchValue
        End If



Next counter

End With

End Sub

I used the MATCH function in order to set the start of the range. i.e. if there is a match in the target table the range will shift from the location of the match downwards. If the match is at on the same level then it does not shift the range in order to match the same-level entry afterwards it is supposed to shift by one unit in order to prevent repetitions.

声明你的Target_MatchValue As Variant所以不会引发错误,而是你必须处理你想要做什么IsError(Target_MatchValue)(当没有找到匹配项时)
