Hi Leute, bin absoluter Neuling auf dem Gebiet der Windowsprogrammierung und habe so meine Schwierigkeiten. Folgendes ich möchte eine Dialogbox aus meinem Menu aufrufen. Das klappt auch irgendwie, allerdings wird die Dialogbox im
Hauptfenster angezeigt und nicht als verschiebbares Fenster (so wie eine Dialogbox eben sein sollte). Dann ist nichts mehr anwählbar und man muss das prog mit dem taskmanager schliessen (vielleicht auch weil die buttons nicht funktionieren.. aber warum?). Ich denke für jemanden, der Ahnung von der Materie hat, sollte das Lösen des Problems ein leichtes sein... Bitte um Hilfe, dennich trete seit tagen auf der stelle und alles gegoogle hat nichts geholfen. nutze visual studio 2005 c++ mit opengl.
vielen Dank im Voraus!
