Access 2010の VBA オートメーションを使用して、 Excel 2010を使用してグラフを作成しています。私のコードは正常に動作しますが、孤立した Excel.exe プロセスが実行されたままになります。別のモジュールでの Excel VBA 関数の呼び出しに問題があることを突き止めました。この関数の呼び出しを削除すると、コードの終了時に Excel プロセスが閉じられます。この関数は、範囲を として宣言し、メソッドを として明示的に参照するFindAll
など、Access で実行できるように変更を加えたChip Pearson のものです。孤立した Excel プロセスが実行されたままにならないように、この関数をどのように変更する必要がありますか?Excel.Range
Union
Excel.Application.Union
次のコードは、メイン プロシージャで Excel アプリケーションをバインドします。
Dim oApp As New excel.Application
Dim oBook As excel.Workbook
Dim oSheet As excel.Worksheet
Set oBook = oApp.Workbooks.Add
Set oSheet = oBook.Worksheets(1)
次に、最後に:
oBook.Close False
oApp.Quit
Set oSheet = Nothing
Set oBook = Nothing
Set oApp = Nothing
そして、次の行を使用して FindAll を呼び出しています。
b = FindAll(oSheet.Range("a2", oSheet.Range("a2").End(xlDown)), strWellID).Rows.Count
FindAll
機能は以下です。

' This module is described at www.cpearson.com/Excel/FindAll.aspx
' Requires Excel 2000 or later.
'
' This module contains two functions, FindAll and FindAllOnWorksheets that are use
' to find values on a worksheet or multiple worksheets.
'
' FindAll searches a range and returns a range containing the cells in which the
' searched for text was found. If the string was not found, it returns Nothing.
' FindAllOnWorksheets searches the same range on one or more workshets. It return
' an array of ranges, each of which is the range on that worksheet in which the
' value was found. If the value was not found on a worksheet, that worksheet's
' element in the returned array will be Nothing.
'
' In both functions, the parameters that control the search have the same meaning
' and effect as they do in the Range.Find method.
