Titelleiste im fullscreen

[FloLabu]

Hi!

Sorry, dass ich hier so nen langen quelltext posten muss. Doch ich hab anhand eines Tutorials mir ein kleines DirectDraw Programm geschrieben, wo es erst mal initialisiert wird und dann der hintergrund schwarz gezeichnet wird. Doch oben ist trotz fullscreen immernoch die titelleiste zu sehen. Ich kann den Fehler einfach nicht finden. In der Original-Source-Datei des Tutorials ist die Titelleiste nicht zu sehen, aber ich kann keine Unterschiede finden...

Mein Sourcecode:

#include <windows.h>

Tut mir Leid, wenn ihr euch so viel durchlesen müsst, doch ich kann den Fehler nicht lokalisieren.

Danke schonmal für eure Hilfe,

Probier mal, WS_OVERLAPPEDWINDOW bei wc.style mit anzugeben.

[FloLabu]

Nee, klappt leider auch nicht. Es scheint aber zu funktionieren, wenn ich das fenster statt mit WS_OVERLAPPEDWINDOW mit WS_POPUP erstelle, dass es dann geht... Ist doch auch ok, oder?

Trotzdem danke,
