MediaPlayer und Playliste?

[mlspider]

Hi,

ich bin seit längerem dabei, meinen Player auf eine neuere Version zu bringen. Ich möchte einen CD-Player mit einer Playlist proggen, die sich die Titelinfos von Freedb.org holt. Soweit klappt auch alles. Meine Listbox, was die Playliste darstellen soll wird mit den Titeln gefüllt.

Nun mein Problem, da ich denke, dass ich mir eine Sackgasse gebaut habe. Wie kann ich nun den MediaPlayer dazu bringen auf Klick in meiner Listbox den entsprechenden Titel abzuspielen? Und wie könnte die automatische Selektion des gerade laufenden Titels realisiert werden.

Hier mal der "unsaubere" Quellcode meines Projekts.

Hätte ich fast vergessen. Listbox3 soll die Playliste sein.

Sorry, das ich hier die gesamte Unit poste.

Delphi-Quellcode:

wäre für jede Hilfe dankbar, da ich der Meinung bin, in eine Sackgasse geraten zu sein.
