Hallo erstmal,
ich hab da mal ne frage ich hab jetzt angefangen mich in direct sound einzuarbeite und ma n kleines script geschrieben. Geht auch alles gut compiliert und so aber wenn ich dann die funktion CreateSoundBuffer() aufrufe um mir einen secondary buffer zu erstellen kommt meine fehlermeldung das dat net geklappt hat. woran könnte das liegen?
Hier der code:
//Datei: DirectSound.h
#include <dsound.h>
#define SND0 0

#define ANZ_SOUNDS_GESAMT 1
bool xxxDSound_Initialisieren(HWND hwnd);

bool xxxDSound_Buffer_erzeugen(const char* filename,
LPDIRECTSOUNDBUFFER* lpDSB);
bool xxxDSound_Wave_laden(const char* filename, WAVEFORMATEX* wf,
DWORD* pdwLaenge, PBYTE* ppbyWDat);
bool xxxDSound_Wave_Format(HMMIO hmmio, WAVEFORMATEX* wf);

Wenn mir da einer helfen könnte wäre ich da sehr dankbar drüber.
