对（键、字符串）对的动态集进行排序VB6

谁能告诉我用VB6对键设置的动态（键、字符串）排序的最佳方法是什么。 我尝试过使用VBA.collections和2D数组。但他们似乎有一个大的解决办法来做这类事情。 我还尝试了本文中提到的

mscomctlib.ListView

但添加此项时会出现一个错误，即“未设置对象或带块变量”。如果我能看完这些，我就可以按列对列表视图进行排序，并继续前进

请任何人告诉我一个克服这个问题的方法，或者如果你有其他方法，请告诉我

谢谢。

尝试使用记录集对象进行如下排序

Option Explicit

Private Function pvSortImpl(vData As Variant, _
            ByVal lKeyType As Long, _
            ByVal lKeySize As Long, _
            ByVal lValueType As Long, _
            ByVal lValueSize As Long) As Variant
    Const adFldIsNullable As Long = 32
    Dim rs              As Object
    Dim vElem           As Variant
    Dim vFields         As Variant
    Dim vRetVal         As Variant

    Dim oFldValue       As Object

    Set rs = CreateObject("ADODB.Recordset")
    rs.Fields.Append "Key", lKeyType, lKeySize, adFldIsNullable
    rs.Fields.Append "Value", lValueType, lValueSize, adFldIsNullable
    rs.Open
    vFields = Array(0, 1)
    For Each vElem In vData
        rs.AddNew vFields, vElem
    Next
    If rs.RecordCount = 0 Then
        vRetVal = Array()
    Else
        rs.Sort = "Key"
        ReDim vRetVal(0 To rs.RecordCount - 1) As Variant
        Set oFldKey = rs.Fields("Key")
        Set oFldValue = rs.Fields("Value")
        rs.MoveFirst
        Do While Not rs.EOF
            vRetVal(lIdx) = Array(oFldKey.Value, oFldValue.Value)
            lIdx = lIdx + 1
            rs.MoveNext
        Loop
    End If
    pvSortImpl = vRetVal
End Function

Public Function SortNumeric(vData As Variant) As Variant
    Const adDouble      As Long = 5
    Const adVarWChar    As Long = 202

    SortNumeric = pvSortImpl(vData, adDouble, 0, adVarWChar, 1000)
End Function

Public Function SortStrings(vData As Variant) As Variant
    Const adVarWChar    As Long = 202

    SortStrings = pvSortImpl(vData, adVarWChar, 202, adVarWChar, 1000)
End Function

Private Sub Form_Load()
    Dim vResult         As Variant

    vResult = SortStrings(Array(Array("bbb", "test"), Array("aaa", Now)))
    Debug.Print Join(vResult(0), "=>")
    Debug.Print Join(vResult(1), "=>")
    vResult = SortNumeric(Array(Array("33", "test"), Array("2.2", Now), Array("22", "Proba")))
    Debug.Print Join(vResult(0), "=>")
    Debug.Print Join(vResult(1), "=>")
    Debug.Print Join(vResult(2), "=>")
End Sub

这在即时窗口中打印

aaa=>9/21/2018 11:50:19 AM
bbb=>test
2.2=>9/21/2018 11:50:19 AM
22=>Proba
33=>test

您是否使用了

Set

新建

lvSelectedStyles

？我尝试过，但设置lvSelectedStyles=New。。。vb在这里没有给出mscomctlib.ListView的建议。我被卡住了。似乎无法使用New创建ListView，所以我看到了几个选项：首先，可以将ListView放到隐藏窗体上。其次，您可以使用字典并编写一些自定义代码对其进行排序。这个网站和其他网站上都有一些例子。@BrianMStafford我在表单中创建了一个listview（不可见），使用listview.sort，我现在可以按照自己的意愿进行排序了。谢谢。可以创建一个VB（.NET）或C#类，它可以使用.NET framework集合执行此操作，并从VB6访问该类。但这可能不是最方便/直接的方法。您是否使用
