ASP-VB-Dateien Hochladen, nicht mit original-Datei-Namen! Verwenden Sie ein URL-Schema, um den Namen der hochgeladenen Dateien.

Guten Tag An Alle!

Arbeite ich an einer ASP VB-Skript, das ich online gefunden kostenlos. Es funktioniert Super auf meinem web server, aber die Lösung verwenden Sie nur den original-Dateinamen zu speichern, um die web-server-Verzeichnisse.

Ich bin auf der Suche nach einem ASP-Datei-Uploader Lösung, wo ich kann, übergeben Sie eine URL:

http://globalbanke.com/uploadFiles.asp?CustomName=Red

Dann der uploader öffnet sich die Seite und der Benutzer kann die Datei laden und dann die Datei auf dem server gespeichert, die als "Rot"

Ich bin mit dem hochladen.save () - Methode.
Diese Zeile hier:

filePath = Pfad & request.querystring("CustomName")

Gibt mir ein server-Fehler, aber wenn ich es zu ändern "test.txt" es speichert es als solche.

Also meine Frage ist, Wie verwende ich die URL Abfrage mit dem Namen für den server?

Hier ist die ASP-Klasse Methoden
