VBA和数组

Keith · 发表于 2007-2-1 16:25:33

好吧，现在我完全迷失了我正在做的这个数组搜索的东西。我理解其中的逻辑，但没有任何效果。实际上，它第一次工作，但之后不起作用。代码 1 是我试图使工作的版本。代码2是一个简化的版本，我试图让它工作，所以我可以修复代码1。

Option Explicit
Dim FoundItems() As String, intType(0 To 1) As Integer, varData(0 To 1) As Variant
Dim objSelCol As AcadSelectionSets, objSelSet As AcadSelectionSet, objBlkRef As AcadBlockReference
Dim varArray1 As Variant, intCount As Integer
Public Sub PMS_v2()
Erase FoundItems
    Set objSelCol = ThisDrawing.SelectionSets
    For Each objSelSet In objSelCol
        If objSelSet.Name = "PMS" Then
            objSelSet.Delete
            Exit For
        End If
    Next
    Set objSelSet = objSelCol.Add("PMS")
    intType(0) = 0: varData(0) = "INSERT"
    intType(1) = 2: varData(1) = "*"
    objSelSet.Select Mode:=acSelectionSetAll, filtertype:=intType, filterdata:=varData
    For Each objBlkRef In objSelSet
        If objBlkRef.HasAttributes Then
            varArray1 = objBlkRef.GetAttributes
            For intCount = LBound(varArray1) To UBound(varArray1)
                Select Case varArray1(intCount).TagString
                    Case "STORESNUMBER"
                        strStoresNumber = varArray1(intCount).TextString
                        IncrimentCount strStoresNumber
                End Select
            Next intCount
        End If
    Next
    'Now Extract the Information
    'Extract to Tab Delimited File
    Dim fso, fl, fln, s
    Dim j As Integer
    fln = "M:\PARTS-LIST\PMS.txt"
    Set fso = CreateObject("Scripting.FileSystemObject")
    If fso.FileExists(fln) Then
        fso.DeleteFile fln
    End If
    Set fl = fso.CreateTextFile(fln)
    For j = 1 To UBound(FoundItems)
        s = GetPartInformation(FoundItems(j, 0), FoundItems(j, 1))
        fl.WriteLine s
    Next
    fl.Close
End Sub
Private Function GetPartInformation(StoresNumber As String, Quantity As String) As String
    Dim objXML As New DOMDocument
    Dim objRoot As IXMLDOMElement
    Dim objLNode As IXMLDOMElement
    Dim s As String
    objXML.Load "M:\PARTS-LIST\partslist.xml"
    Set objRoot = objXML.documentElement
    For Each objLNode In objRoot.childNodes
        If StoresNumber = objLNode.childNodes(0).Text Then
            s = Quantity & vbTab & StoresNumber & vbTab & objLNode.childNodes(1).Text & vbTab & objLNode.childNodes(2).Text & vbTab & objLNode.childNodes(3).Text
        End If
    Next objLNode
    Set objXML = Nothing
    GetPartInformation = s
End Function
Private Sub IncrimentCount(StoresNumber As String)
On Error Resume Next
Dim i As Integer, m As Integer
Dim found As Boolean
    found = False
    m = UBound(FoundItems, 1)
    If Err.Number = 9 Then
        m = 0
    Else
        For i = 1 To m
            If FoundItems(i, 0) = StoresNumber Then
                found = True
                FoundItems(i, 1) = CInt(FoundItems(i, 1)) + 1
            End If
        Next
    End If
    If found = False Then
        ReDim Preserve FoundItems(m + 1, m + 1)
        FoundItems(m + 1, 0) = StoresNumber
        FoundItems(m + 1, 1) = 1
    End If
End Sub

当您运行例程时，我会将您的FoundItems重置为零......即代替擦除......只有我......但是您可以使用擦除......我只是发现它不可靠......此外...你试图重拨数组的两个维度，你只能重拨最后一个维度...因此而不是
ReDim保留FoundItems（m+1， m+1）'这实际上是不正确的，因为你只有2个维度的第二个值（0&1），但是它必须被转过来，并且ReDim只有第二个维度...
ReDim保留FoundItems（1， m+1）因此您有无限的dims与2个值即FoundItems（0， x）和FoundItems（1， x）...
我已经编辑了下面的代码，因为我看到了它，但我还没有测试它，因为我这里没有任何方便测试它的东西.

我昨天回家前就知道了。回到绘图板。不过我有个主意。。。

fixo · 发表于 2007-2-2 10:14:56

几年前我尝试过XML。据我回忆，这相当简单明了。您必须为XML添加一个引用—记不清具体是什么了— Microsoft XML(某个版本号？)

fixo · 发表于 2008-10-27 17:52:39

我同意，写出XML应该很容易。这是我担心的阵列。我从来没有真正使用过它们。不过，这个概念看起来相当直截了当。我会随时通知你的

Keith · 发表于 2008-10-28 08:25:22

好吧，我卡住了。我不知道如何发送到XML。我知道我必须把它发送到子节点，但是我似乎不能让它们被识别。有人试过这个吗？

这是一个让你开始学习的例子
