Screen Saver Konfigurationsdialog

[Shaggy]

Hi,

ich habe einen netten Screensaver programmiert und mich da an das Beispiel aus der MSDN gehalten. Der Saver läuft auch problemlos, leider wird der Konfigurationsdialog nicht angezeigt. Und das, obwohl ich bisher nur die Sachen aus der MSDN kopiert habe.

Hier die Dateien:

// SyMe.rc
#include "resource.h"
#include "afxres.h"

Ich hoffe, es kann mir jemand erklären woran das liegt und was ich anders machen muss.

Thanks im Voraus,
