将列表框的选择存储在数组中 VBA

Question

我正在尝试存储用户从用户表单中的列表框中选择的内容。我目前正在使用 public 属性 get 从另一个模块的用户表单中检索我的值。

这是我的用户表单：

Public Property Get DateFrom() As String
    DateFrom = TextBox1.Text
End Property
Public Property Get DateTo() As String
    DateTo = TextBox2.Text
End Property
Public Property Get Cost() As String
    Cost = TextBox3.Text
End Property
Public Property Get Expense() As String
    Expense = TextBox4.Text
End Property

从另一个模块调用时有效

Sub FormNLReport()

    With New NLTrans
    
    .Show vbModal
    
    On Error GoTo CloseF
    NLReport .DateFrom, .DateTo, .Cost, .Expense
   
   
  CloseF: Unload NLTrans
        Exit Sub
    
    End With

End Sub

然后链接到这个子 class:

Sub NLReport(DateFrom As String, DateTo As String, Cost As String, Expense As String)

但是，我现在想添加一个多选列表框，但对如何将其从用户窗体传递到模块感到困惑。目前我已经这样做了：

Public Property Get Items(ByRef i As Long) As String

For i = 0 To ListBox1.ListCount - 1
    If ListBox1.Selected(i) = True Then
    Items(i) = ListBox1.List(i)
    MsgBox (Items(i))
    End If
Next i
End Property

我的其他模块：

Sub FormNLReport()

    With New NLTrans
    
    .Show vbModal
    
    On Error GoTo CloseF
    NLReport .DateFrom, .DateTo, .Cost, .Expense, .Items()
   
   
CloseF: Unload NLTrans
        Exit Sub
    
    End With

End Sub

Sub NLReport(DateFrom As String, DateTo As String, Cost As String, Expense As String, Items() As String)

然后当我尝试从另一个模块调用它时出现错误：

这属性将 return 所选值的数组：

Public Property Get Items() As String()
    Dim i As Long, selected As Long
    Dim selectedItems() As String
    
    For i = 0 To ListBox1.ListCount - 1
        If ListBox1.selected(i) = True Then
            ReDim Preserve selectedItems(selected)
            selectedItems(selected) = ListBox1.List(i)
            selected = selected + 1
        End If
    Next i
    
    items = selectedItems
End Property

你可以这样传递：

NLReport Me.DateFrom, Me.Items

并像这样访问它：

Sub NLReport(DateFrom As String, ArrayItems() As String)
    MsgBox ArrayItems(0) '// assumes at lease 1 selected item
End Sub
