Reverse For Next Loop 未完全循环

Question

我有一个包含列表框和命令按钮的 excel 用户表单。我希望能够在列表框中选择多行，并在使用命令按钮时将它们从数据库范围中删除。

命名范围通过字典运行，其中键作为范围单元格值，项目作为单元格地址。通过字典弹出列表框选择，返回要删除的单元格位置。

目前，当我进行选择时，最底部的选择是唯一删除的条目。 For Next 循环应该从 listbox.count-1 开始，一直到 0。但是，它似乎没有完全循环并且没有错误消息。想法？

Private Sub RemoveAnalyst()
' Select Tools->References from the Visual Basic menu.
' Check box beside "Microsoft Scripting Runtime" in the list.
Dim ws          As Worksheet
Dim i           As Long
Dim Location    As String
Dim MsgDelete   As String
Dim xCount   As Integer
Dim xFound      As Integer
Dim Cell        As Range
Dim dict        As Scripting.Dictionary

Set ws = ThisWorkbook.Sheets("Lists")

'Build Dictionary
Set dict = New Scripting.Dictionary
    dict.CompareMode = vbTextCompare  'Capitalization does not apply to dictionary

    For Each Cell In Range("Name").Cells 'Add named range to dictionary
        With Cell
            dict(Cell.Value) = Cell.Address(RowAbsolute:=False, ColumnAbsolute:=False) 'Key = Cell value (ie. Analyst name), Item = Cell address (ie. A2)
        End With
    Next Cell

    Set xCount = RemoveAnalystLB.ListCount - 1
    For i = xCount To 0 Step -1 'Reverse For Loop
        If RemoveAnalystLB.Selected(i) Then
            With ws
                Location = dict(RemoveAnalystLB.List(i)) 'Find Cell location via dictionary function
                xFound = xFound + 1
                MsgDelete = MsgDelete & vbCrLf & RemoveAnalystLB.List(i)
                .Range(Location).Delete Shift:=xlUp 'Delete cell at specified location
            End With
        End If
    Next i

    Set dict = Nothing
    Unload Remove_Analyst_Form 'Close out userform

    If xFound <> 0 Then MsgBox ("Analyst(s):" & MsgDelete & vbCrLf & "have been deleted from the database.") 'Msg names have been deleted


End Sub

试试这个

Private Sub RemoveAnalyst()
'Tools ->References -> Microsoft Scripting Runtime
'-------------------------------------------------
Dim ws          As Worksheet
Dim dict        As Scripting.Dictionary
Dim cell        As Range
Dim rng         As Range
Dim location    As String
Dim msgDelete   As String
Dim xCount      As Integer
Dim xFound      As Integer
Dim i           As Long

Set ws = ThisWorkbook.Sheets("Lists")
Set dict = New Scripting.Dictionary
dict.CompareMode = vbTextCompare

For Each cell In Range("Name").Cells
    With cell
        dict(cell.Value) = cell.Address(RowAbsolute:=False, ColumnAbsolute:=False)
    End With
Next cell

xCount = RemoveAnalystLB.ListCount - 1

For i = xCount To 0 Step -1
    If RemoveAnalystLB.Selected(i) Then
        With ws
            location = dict(RemoveAnalystLB.List(i))
            xFound = xFound + 1
            msgDelete = msgDelete & vbCrLf & RemoveAnalystLB.List(i)
            If rng Is Nothing Then Set rng = .Range(location) Else Set rng = Union(rng, .Range(location))
        End With
    End If
Next i

Set dict = Nothing
Unload Remove_Analyst_Form

If Not rng Is Nothing Then rng.Delete Shift:=xlUp
If xFound <> 0 Then MsgBox ("Analyst(s):" & msgDelete & vbCrLf & "Have Been Deleted From The Database.")
End Sub
