  • was geht ab!
    hab n kleines problem.
    erstelle grad ne trackbar mit burningcontrol aus nem tutorial.
    nach einigen fehlern die ich nach langer zeit endlich mal geloest hab zeigt der compiler an das der code keine fehler hat und zeigt auch keine warnungen an.trotzdem kommt kein resultat.nicht mal ein leeres fenster.
    kann mir einer helfen bitte.denn ohne das ich die headerfiles nicht nutzen kann macht das keinen sinn so richtig.

    hier der code:

    #if defined(UNICODE) && !defined(_UNICODE)
    #define _UNICODE
    #elif defined(_UNICODE) && !defined(UNICODE)
