CreateRecordset-Methode (Beispiel) (VBScript)
Wichtig
Ab Windows 8 und Windows Server 2012 sind RDS-Serverkomponenten nicht mehr im Windows-Betriebssystem enthalten (weitere Details finden Sie unter Windows 8 und Windows Server 2012 Compatibility Cookbook). RDS-Clientkomponenten werden in einer zukünftigen Version von Windows entfernt. Vermeiden Sie die Verwendung dieses Features in neuer Entwicklungsarbeit, und planen Sie, Anwendungen zu ändern, die derzeit dieses Feature verwenden. Anwendungen, die RDS verwenden, sollten zu WCF Data Servicemigrieren.
In diesem Codebeispiel wird ein Recordset- auf der Serverseite erstellt. Es verfügt über zwei Spalten mit jeweils vier Zeilen. Schneiden Sie den folgenden Code aus, und fügen Sie ihn in Editor oder einem anderen Texteditor ein, und speichern Sie ihn als CreateRecordsetVBS.asp.
