[Excel VBA] Rangeオブジェクトの2次元配列の作成

指定のセル範囲の各Rangeオブジェクトを２次元配列に格納

Public Function CreateRangeArray( _
        TargetRange As Range, _
        RangeArray() As Range, _
        Optional BaseIndex As Long = 0 _
    )

    If Not TypeOf TargetRange Is Range Then
        CreateRangeArray = 1
        Exit Function
    End If

    If BaseIndex < 0 Then
        CreateRangeArray = 2
        Exit Function
    End If

    Dim RowList As Object, ColList As Object
    Set RowList = CreateObject("System.Collections.SortedList")
    Set ColList = CreateObject("System.Collections.SortedList")

    Dim Cell As Range
    For Each Cell In TargetRange.Cells
        If Not RowList.ContainsKey(Cell.Row) Then
            Call RowList.Add(Cell.Row, 0)
        End If
        If Not ColList.ContainsKey(Cell.Column) Then
            Call ColList.Add(Cell.Column, 0)
        End If
    Next

    ReDim RangeArray( _
            0 + BaseIndex To RowList.Count - 1 + BaseIndex, _
            0 + BaseIndex To ColList.Count - 1 + BaseIndex _
        ) As Range

    Dim r As Long, c As Long
    For Each Cell In TargetRange.Cells
        r = RowList.IndexOfKey(Cell.Row)
        c = ColList.IndexOfKey(Cell.Column)
        Set RangeArray(r + BaseIndex, c + BaseIndex) = Cell
    Next

    CreateRangeArray = 0

End Function

[Excel VBA] 選択範囲の正規化（？）

複数のセル範囲を正規化します。

Public Function NormalizeRange(Ranges As Range) As Range

    Dim Retval As Range
    Dim i As Long

    If Not Ranges Is Nothing Then
        Set Retval = Ranges.Areas(1)
        For i = 2 To Ranges.Areas.Count Step 1
            Set Retval = Application.Union(Retval, Ranges.Areas(i))
        Next
    End If

    Set NormalizeRange = Retval

End Function

[Excel VBA] 正規表現パターンと一致する文字列を置換処理するワークシート関数

Public Function RegexReplace( _
        Source As String, _
        Pattern As String, _
        Replacement As String, _
        Optional Flags As String = "" _
    )

    With New VBScript_RegExp_55.RegExp
        If Flags = "" Then
            .Global = False
            .IgnoreCase = False
            .MultiLine = False
        Else
            .Global = Flags Like "*g*"
            .IgnoreCase = Flags Like "*i*"
            .MultiLine = Flags Like "*m*"
        End If
        .Pattern = Pattern
        RegexReplace = .Replace(Source, Replacement)
    End With
