✔ UPnP Description download mit http get() Methode

[chett]

Moin Moin,

ich beschäftige mich mit UpnP und versuche mit dem Cyberlink Developement Package eine "Control Punkt" zu entwickeln.

Ich habe also einen Control Punkt erzeugt, bekomme auch die Benachrichtungen anderer Upnp Geräte im netz mitgeteilt; was ich aber nicht auf dei Reihe bringe ist: Der Download der Geräte-Beschreibung.

Alle Informationen bisher bekam ich aus dem Object packet; wie ich aber an die Adresse der Beschreibung komme check ich nicht.

Kennt sich jemand aus?

ach ja der Code...
