Ich hab mal ein klavir auf Winapi geschrieben und es funtz eigenlich wunderbar , aber wenn ich mehrere knöpf gleichzeitig drücken will funtz das nicht mehr

ps: den code hab ich von heneksoft.de /win32 programmierung ..

und immer wenn ich den code das 2te mal complieren möchte , schießt "Dev Cpp" ab - genau so wie alle anderen complirer

hier der ganze code: (fals wer noch anderes damit vor hat *g* :D:P )

(laüft erst mit den WINMM sound linker )

und noch was: wie wird der code in son weisen kästchen wieder gegeben?

#include <stdio.h>
