VB6 アプリケーションが C:\ProgramData\ フォルダー内のファイルに書き込もうとしています。これを行う理由は、コンピューター上のユーザーがアプリケーションを使用して同じファイルに書き込むことができるようにするためです。ProgramData フォルダーには、すべてのユーザーが共有するアプリケーション データを格納できることがわかっています。

したがって、

C:\Users\[UserName]\AppData\Local
C:\Users\[UserName]\AppData\LocalLow
C:\Users\[UserName]\AppData\Roaming

特定のユーザー名を持つこれらのパスは、私のアプリケーションには適していません。

しかし、Windows 7 で標準ユーザーとして実行すると、ProgramData フォルダー内のファイルに書き込む権限がないことがわかりました。タスクを実行できる他の方法はありますか?

本当にSHGetSpecialFolderPath()APIを使用する必要があります。

これをモジュール (またはフォームに入れて非公開に変更) に入れます。

Private Declare Function SHGetSpecialFolderPath Lib "SHELL32.DLL" Alias "SHGetSpecialFolderPathA" (ByVal hwndOwner As Long, ByVal pszPath As String, ByVal nFolder As Long, ByVal fCreate As Long) As Long

Public Function GetSpecialFolder(ByVal csidl As Long) As String
    Dim X As Long
    GetSpecialFolder = Space$(261&)
    If SHGetSpecialFolderPath(0&, GetSpecialFolder, csidl, 1&) Then
        GetSpecialFolder = Left$(GetSpecialFolder, InStr(1&, GetSpecialFolder, vbNullChar, vbBinaryCompare) - 1&)
    Else
        Err.Raise -1&, , "Could not find special folder " & csidl & "."
    End If
End Function

次に、次GetSpecialFolder()の定義のいずれかでこれを呼び出すことができます。

これにより、すべてのオペレーティング システムとの互換性が保証されます。各定義の値を取得するには、Google で検索するか、Win32 API ツールを確認してください。ここにたくさんあります：

次のパスは、すべてのユーザーが使用でき、特別な権限がなくても書き込み可能です。
