单独的列表框项目为每个循环执行一次

Question

我在分离列表框项目时遇到问题，因此我可以循环运行它们。我知道这个自动取款机会收取所有物品并尝试将它们运行，但我不知道如何将它们分开。 代码如下：

Dim SelectedItems As String
Dim LastRow As Long

LastRow = ActiveSheet.Range("F1").SpecialCells(xlCellTypeLastCell).Row

For i = 0 To ListBox2.ListCount - 1
If ListBox2.Selected(i) = True Then
SelectedItems = SelectedItems & ListBox2.List(i) & vbNewLine
End If
Next i

If SelectedItems = "" Then
MsgBox "Please select minimum one country"
Else

For Each SelectedItems In ListBox2

    For i = 11 To LastRow

    If Range("F" & i).Value = SelectedItems Then
    Rows(i).EntireRow.Hidden = True
    Else: Rows(i).EntireRow.Hidden = False
    End If

    Next i
Next SelectedItems

有人可以帮忙吗？

Dim SelectedItems As String, LastRow As Long
Dim selItem As Variant, selItems As Variant

LastRow = ActiveSheet.Range("F1").SpecialCells(xlCellTypeLastCell).Row

For i = 0 To ListBox2.ListCount - 1
    If ListBox2.Selected(i) = True Then
        SelectedItems = SelectedItems & ListBox2.List(i) & vbNewLine
    End If
Next i

Stop
If SelectedItems = "" Then
    MsgBox "Please select minimum one country"
Else
    SelectedItems = left(SelectedItems, Len(SelectedItems) - 1)
    selItems = Split(SelectedItems, vbNewLine)
    For Each selItem In selItems
        For i = LastRow To 11 Step -1
            If CStr(Range("F" & i).value) = CStr(selItem) Then
                Stop
                Rows(i).EntireRow.Hidden = True
                'Else: Rows(i).EntireRow.Hidden = False
            End If
        Next i
    Next
End If

如果不将字符串拆分为元素，您的代码将无法识别字符串中的每个选定项目。 编辑：转换测试代码中的代码。我将（在评论中）向您解释如何检查。

注意：我只是想让你的代码可行。否则，您可以使用 Excel AutoFilter 直接进行过滤（当然是在 VBA 中）...

所以只是一个关于我如何解决这个问题的小例子，避免多个循环：

_{用户表单示例代码：}

Option Explicit

Private Sub CommandButton1_Click()

Dim dict As Object: Set dict = CreateObject("Scripting.Dictionary")
Dim x As Long, lr As Long
Dim rng As Range

'Check if anything has been selected at all
If Me.ListBox1.ListIndex = 0 Then Exit Sub

'Capture selected items in your ListBox
For x = 0 To Me.ListBox1.ListCount - 1
    If Me.ListBox1.Selected(x) Then
        dict(ListBox1.List(x)) = 1
    End If
Next x

'Filter the range accordingly
With Sheet1
    lr = .Cells(.Rows.Count, 1).End(xlUp).Row
    Set rng = .Range("A1:A" & lr)
    rng.AutoFilter 1, Array(dict.keys), xlFilterValues
End With

End Sub

Private Sub UserForm_Initialize()

Dim lr As Long

'Populate your ListBox
With Sheet1
    lr = .Cells(.Rows.Count, 1).End(xlUp).Row
    Me.ListBox1.RowSource = .Range("A2:A" & lr).Address
End With

End Sub
