excel - 无法在 Excel VBA 用户窗体中设置多列列表框的选定属性

Question

我无法检查多列用户表单列表框中的项目。行lstPreConditionLogic.Selected(lstPreConditionLogic.ListCount) = True生成以下错误:

Run-time error '380': Could not set the Selected property. Invalid property value

我尝试将值设置为 -1 , checked但它没有用。

VBA代码

Private Function FillPreConditionLogicList()
    Dim varTemp             As Variant
    Dim intLoop             As Integer
    Dim strExpression       As String
    Dim PreConditionLogic   As clsPreConditionLogic

    With lstPreConditionLogic
        .ColumnCount = 3
        .ListStyle = fmListStyleOption
        .MultiSelect = fmMultiSelectMulti
        strExpression = TrimBlank(shtExpressionEditor.Range("rngExpText").Offset(, 1).Value)
        For intLoop = 0 To mDicPreConditionLogic.Count - 1
            Set PreConditionLogic = mDicPreConditionLogic.Items(intLoop)
            .AddItem
            .List(intLoop, 0) = PreConditionLogic.Name
            .List(intLoop, 1) = PreConditionLogic.StartEnclosure
            .List(intLoop, 2) = PreConditionLogic.EndEnclosure
            varTemp = GetEnclosedString(strExpression, PreConditionLogic.StartEnclosure, PreConditionLogic.EndEnclosure)
            If varTemp <> "" Then
                lstPreConditionLogic.Selected(lstPreConditionLogic.ListCount) = True '//Gives Error
                strExpression = varTemp
            End If
        Next
    End With
End Function

您必须减去 -1来自您的.ListCount …

lstPreConditionLogic.Selected(lstPreConditionLogic.ListCount - 1) = True

因为列表索引统计在 0但例如如果 ListCount = 5那么这5个条目的索引是 0 , 1 , 2 , 3 , 4这意味着最后一个有效索引是 .ListCount - 1 .
