我已经使用CreateObject("Scripting.Dictionary")在VBA中创建了一个字典，将源单词映射到要替换文本中的目标单词（实际上是用于混淆）。
不幸的是，当我按照下面的代码进行实际替换时，它会按照添加到字典中的顺序替换源单词。如果我有"Blue"和"Blue Berry"，那么"Blue Berry"中的"Blue"部分将被第一个目标替换，而"Berry"保持不变。
'This is where I replace the values
For Each curKey In dctRepl.keys()
largeTxt = Replace(largeTxt, curKey, dctRepl(curKey))
Next
我想通过首先按照最长的键长将字典的键排序，然后像上面那样进行替换来解决这个问题。问题是我不知道如何以这种方式对键进行排序。
看起来我自己已经想出来了。 我创建了以下函数，似乎可以完成任务：
Public Function funcSortKeysByLengthDesc(dctList As Object) As Object
Dim arrTemp() As String
Dim curKey As Variant
Dim itX As Integer
Dim itY As Integer
'Only sort if more than one item in the dict
If dctList.Count > 1 Then
'Populate the array
ReDim arrTemp(dctList.Count - 1)
itX = 0
For Each curKey In dctList
arrTemp(itX) = curKey
itX = itX + 1
Next
'Do the sort in the array
For itX = 0 To (dctList.Count - 2)
For itY = (itX + 1) To (dctList.Count - 1)
If Len(arrTemp(itX)) < Len(arrTemp(itY)) Then
curKey = arrTemp(itY)
arrTemp(itY) = arrTemp(itX)
arrTemp(itX) = curKey
End If
Next
Next
'Create the new dictionary
Set funcSortKeysByLengthDesc = CreateObject("Scripting.Dictionary")
For itX = 0 To (dctList.Count - 1)
funcSortKeysByLengthDesc.Add arrTemp(itX), dctList(arrTemp(itX))
Next
Else
Set funcSortKeysByLengthDesc = dctList
End If
End Function

我正在寻找一个简单的VBA函数，在Microsoft Excel中按键值升序排序字典。
我对neelsg的代码进行了一些小修改以适应我的需求（请参见下面的'//注释以获取修改详情）：
'/* Wrapper (accurate function name) */
Public Function funcSortDictByKeyAscending(dctList As Object) As Object
Set funcSortDictByKeyAscending = funcSortKeysByLengthDesc(dctList)
End Function
'/* neelsg's code (modified) */
Public Function funcSortKeysByLengthDesc(dctList As Object) As Object
'// Dim arrTemp() As String
Dim arrTemp() As Variant
...
...
...
'Do the sort in the array
For itX = 0 To (dctList.Count - 2)
For itY = (itX + 1) To (dctList.Count - 1)
'// If Len(arrTemp(itX)) < Len(arrTemp(itY)) Then
If arrTemp(itX) > arrTemp(itY) Then
...
...
...
'Create the new dictionary
'// Set funcSortKeysByLengthDesc = CreateObject("Scripting.Dictionary")
Set d = CreateObject("Scripting.Dictionary")
For itX = 0 To (dctList.Count - 1)
'// funcSortKeysByLengthDesc.Add arrTemp(itX), dctList(arrTemp(itX))
d(arrTemp(itX)) = dctList(arrTemp(itX))
Next
'// Added:
Set funcSortKeysByLengthDesc = d
Else
Set funcSortKeysByLengthDesc = dctList
End If
End Function

Set oArrayList = CreateObject("System.Collections.ArrayList")
' Transpose Keys into ones based array.
vKeys = oDictionary.Keys
vKeys = Application.WorksheetFunction.Transpose(vKeys)
For Each vKey In vKeys
Call oArrayList.Add(vKey)
Next
oArrayList.Sort
''oArrayList.Reverse
' Create a new dictionary with the same characteristics as the old dictionary.

End If
Next

Set oNewDictionary = Nothing: Set oArrayList = Nothing

可以通过在过程中添加代码而不创建函数来对键进行排序。
Dim sdkey,tamp As Variant
With CreateObject("Scripting.Dictionary")
sdkey = .keys
For i = LBound(sdkey) + 1 To UBound(sdkey) ' We've listed the unique values as alphabetically.
For j = LBound(sdkey) To UBound(sdkey) - 1
If sdkey(j) > sdkey(i) Then
tamp = sdkey(j)
sdkey(j) = sdkey(i)
sdkey(i) = tamp
End If
Next j
Next i
ReDim tamp(1 To UBound(sd_key) + 1, 1 To 2)
