:upps danke ^^

Wie schaffe ich es jetzt, dass der mir den Verzeichnis-Inhalt auf dem verbundenen ftp-server anzeigt? im mom holt er es ja aus C:\Temp.

Also brauche ich den inhalt vom ftp-server und gleichzeitig bei der verbindung eine abfrage für Username und Password

Credentials mit großem C. Ein wenig mehr Sorgfalt bitte. Und auch ab und zu (z.B. vor dem Posten in einem Forum) in die Dokumentation gucken.
