Microsoft Access PDF Erzeugung / PDF Drucker

Dieses Codebeispiel zeigt wie Sie aus einem Access Report programatisch über VBA Macrocode ein PDF erzeugen. Sie erkennen, wie Sie das COM Interface dazu verwenden können um aus einem VBA Programm programatisch einen PDF Druck anzustarten.

Zuerst wird der 7-PDF Printer ermittelt und als Standarddrucker festgelegt, danach erfolgt der Druck des Access Reports in das PDF Format. Dabei werden benutzerdfinierte Einstellungen gesetzt die unter anderem einen Wasserzeichentext in den PDF Report rendern. Danach erfolgt die PDF Ausgabe und der ursprünglich als Standarddrucker definierte Drucker wird wieder als Standard gesetzt.
