Listview inhalt drucken?

[celinaw]

Hi

Gibt es eine einfache Möglichkeit den Inhalt einer Listview Kopo zu Drucken?
Ich habe bereits sämtlich Foren nach dem Thema durchsucht. Doch die ganzen Beispiele sind zu komplieziert für mich.
Gibt es da nicht eine einfache Lösung wie Z.B die Daten zu exportieren und dan zu Drucken?

Gruß Celina

Hi,

Hier ein Coode von Mr. Google:
(ungetestet)

Delphi-Quellcode:

uses
  Printers;

Hi

Wie gesagt, ich habe bereits gesucht und auch gefunden. Nur nichts brauchbares :thuimb:

Aber ich habe bereits eine andere Interessante Lösung gefunden!

Mit dem Code von folgendem Link kannst du die Daten als HTML speichern! Also fertig zum Drucken :mrgreen:
