URL で指定されたファイルをダウンロードします。
サポートされているプラットフォーム: Windows のみ
VBA:
object.GetRemoteFile URL, LocalFile, IgnoreCache
タイプ: Utility
このメソッドが適用されるオブジェクト。
アクセス: 入力のみ
タイプ: 文字列
ダウンロードするファイルの URL。
アクセス: 出力のみ
タイプ: 文字列
指定した URL のファイル。
アクセス: 入力のみ
タイプ: ブール型
戻り値はありません。
現在または以前のセッション(キャッシュ)に、既にダウンロードしたファイルのリストがある場合、転送の重複を避け、ローカルで使用可能なファイルのコピーを作るのに有効です。IgnoreCache パラメータを True に設定することにより、明示的にダウンロードを強制することができます。この場合、キャッシュは完全に無視されます。
セキュア URL にアクセスするとき、パスワードの入力を求めるダイアログ ボックスが表示されます。このときに、メッセージ ボックスも表示されます(ブラウザでこの動作をオフにしていない場合)。
ファイルをダウンロードするときに内部処理用のテンポラリ ファイルが作成されます。このテンポラリ ファイルにはアクセスしないでください。このファイル内の情報は、AutoCAD セッションが終了する時点で削除されます。
