excel - 特定の行で最後に使用された列を見つける - Excel VBA

Question

特定の行で最後に使用されたセルを取得する必要があります。

例: A1 を選択すると、最後に使用した列は 3 を返すはずです。

行/最後に使用した列 A1/ 3 A2 / 4 A3 / 3 A4 / 3 A5 / 1 A6 / 3 A7 / 4

Answer 1

ダンがチップ ピアソンから投稿した機能は非常に用途が広いです。しかし、おそらくほとんどのアプリケーションではやり過ぎです。もっとシンプルなものを探しているなら：

Sub GetLastColumn()
Dim colRange As Range
Dim rowNum As Long

rowNum = InputBox("Enter the row number")

Set colRange = Cells(rowNum, Columns.Count).End(xlToLeft)
lastCol = colRange.Column

MsgBox colRange.Address

End Sub

' GetLastCell
' By Chip Pearson, chip@cpearson.com, www.cpearson.com
'
' This returns the last used cell in a worksheet or range. If InRange
' is a single cell, the last cell of the entire worksheet if found. If
' InRange contains two or more cells, the last cell in that range is
' returned.
' If SearchOrder is xlByRows (= 1), the last cell is the last
' (right-most) non-blank cell on the last row of data in the
' worksheet's UsedRange. If SearchOrder is xlByColumns
' (= 2), the last cell is the last (bottom-most) non-blank cell in the
' last (right-most) column of the worksheet's UsedRange. If SearchOrder
' is xlByColumns + xlByRows (= 3), the last cell is the intersection of
' the last row and the last column. Note that this cell may not contain
' any value.
' If SearchOrder is anything other than xlByRows, xlByColumns, or
' xlByRows+xlByColumns, an error 5 is raised.
'
' ProhibitEmptyFormula indicates how to handle the case in which the
' last cell is a formula that evaluates to an empty string. If this setting
' is omitted for False, the last cell is allowed to be a formula that
' evaluates to an empty string. If this setting is True, the last cell
' must be either a static value or a formula that evaluates to a non-empty
' string. The default is False, allowing the last cell to be a formula
' that evaluates to an empty string.

' Example:
'       a   b   c
'               d   e
'       f   g
'
' If SearchOrder is xlByRows, the last cell is 'g'. If SearchOrder is
' xlByColumns, the last cell is 'e'. If SearchOrder is xlByRows+xlByColumns,
' the last cell is the intersection of the row containing 'g' and the column
' containing 'e'. This cell has no value in this example.
