VBA 如何在什么都不做的情况下继续显示数组元素

Question

我的 excel 宏有问题。我想在 excel 文件中找到名称并将其复制到不同的单元格。我创建了一个带有名称和 FOR 循环的数组来检查它。在那个 for 循环中，我正在寻找数组中的名称。问题是：如果单元格中的数组中没有名称，程序将停止并给我 MsgBox "No name: " + persons(j) 并在此程序停止后。是否可以向用户提供“文件中没有该名称”的信息并跳过此迭代？

非常感谢您的帮助！

这是我的代码：

Sub wyszukaj()
    Dim persons As Variant
    persons = Array("Dawid", "Mikael", "John", "Alice", "Katerine")
    Dim rowNum As Long
    Dim foundRowNum As String
    Dim findName As String
    Dim j As Long

    For j = LBound(persons) To UBound(persons)
        Dim found As Range
        Dim curSheet As Worksheet
        Dim LastCell As Range
        Dim FirstAddr As String
        With Range("A:A")
            Set LastCell = .Cells(.Cells.Count)
        End With
        Dim nothingInCell As Object
        Set nothingInCell = Nothing

        Set FoundCell = Range("A:A").Find(persons(j), After:=LastCell)

        If FoundCell Is Nothing Then
            MsgBox ("No name: " + persons(j))
        End If

        Debug.Print FoundCell.Value

        If Not FoundCell <> persons(j) Then
            FirstAddr = FoundCell.Address
        End If
        Next j

        Dim counter As Integer
        Dim i As Integer
        counter = 0

        Do Until FoundCell Is Nothing
            counter = counter + 1
            Set FoundCell = Range("A:A").FindNext(After:=FoundCell)
            If FoundCell.Address = FirstAddr Then
                Exit Do
            End If
        Loop

        foundRowNum = FoundCell.Address
        rowNum = Range(foundRowNum).Row

        For i = rowNum To rowNum + counter - 1
            Cells(i, 1).Copy Cells(i, 8)
            Cells(i, 2).Copy Cells(i, 9)
        Next i
End Sub

您需要使用以下结构：

If FoundCell Is Nothing Then 
    'nothing found
Else
    'something found
End If

所有依赖FoundCell的部分都需要在上面的Else部分。

Sub wyszukaj()
    Dim persons As Variant
    persons = Array("Dawid", "Mikael", "John", "Alice", "Katerine")
    Dim rowNum As Long
    Dim foundRowNum As String
    Dim findName As String
    Dim j As Long

    For j = LBound(persons) To UBound(persons)
        Dim found As Range
        Dim curSheet As Worksheet
        Dim LastCell As Range
        Dim FirstAddr As String
        With Range("A:A")
            Set LastCell = .Cells(.Cells.Count)
        End With
        Dim nothingInCell As Object
        Set nothingInCell = Nothing

        Set FoundCell = Range("A:A").Find(persons(j), After:=LastCell)

        If FoundCell Is Nothing Then
            'nothing found
            MsgBox ("No name: " + persons(j))
        Else
            'something found
            Debug.Print FoundCell.Value
    
            If Not FoundCell <> persons(j) Then
                FirstAddr = FoundCell.Address
            End If
        End If
    Next j

    Dim counter As Long
    Dim i As Long
    counter = 0

    Do Until FoundCell Is Nothing
        counter = counter + 1
        Set FoundCell = Range("A:A").FindNext(After:=FoundCell)
        If FoundCell.Address = FirstAddr Then
            Exit Do
        End If
    Loop

    foundRowNum = FoundCell.Address
    rowNum = Range(foundRowNum).Row

    For i = rowNum To rowNum + counter - 1
        Cells(i, 1).Copy Cells(i, 8)
        Cells(i, 2).Copy Cells(i, 9)
    Next i
End Sub
