    Playing a Wave File

    this is what I have so far.........


    Code:
    
    class Sound
    {
    public:
    
    	Sound(char* FileName);
    	PBYTE GetMusicData(){ return SoundData;}
    
    
    
    
    private:
    	HANDLE MusicFile;
    	char Buffer [5];//we add one for the null terminator
    	char DataBuffer[4];
    	unsigned long FmtRead;
    	unsigned long RiffRead;
    	unsigned long WaveRead;
    	unsigned long LengthOfSound;
    	unsigned long LengthBuffer;
    	unsigned long LengthOfSoundWave;
    	unsigned long LengthBufferWave;
    
    	unsigned long GetPastHugeChunks;
    	unsigned long GetPastHugeChunksBuffer;
    
    	unsigned long LengthOfChunk;
    	unsigned long LengthOfChunkBuffer;
    	char* TEMP;
    	PBYTE SoundData;
    
    	PWAVEHDR     WaveHeader;
    	WAVEFORMATEX waveformat ;
    	HWAVEOUT     WaveOut;
    
    
    };
    
    
    
    Sound::Sound(char* FileName)
    {
    	//Load our Wave File
    	
    	Buffer[4]='\0';
    
    	MusicFile=CreateFile(FileName,GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
    	ReadFile(MusicFile,Buffer,4,&RiffRead,NULL);
    	ReadFile(MusicFile,&LengthOfSound,4,&LengthBuffer,NULL);
    	ReadFile(MusicFile,Buffer,4,&WaveRead,NULL);
    	ReadFile(MusicFile,Buffer,4,&FmtRead,NULL);
    	ReadFile(MusicFile,&LengthOfChunk,4,&LengthOfChunkBuffer,NULL);
    	TEMP=new char[LengthOfChunk];
    	ReadFile(MusicFile,TEMP,LengthOfChunk,&RiffRead,NULL);
    	
    	ReadFile(MusicFile,Buffer,4,&WaveRead,NULL);
    	ReadFile(MusicFile,&LengthOfSoundWave,4,&LengthBufferWave,NULL);
    
    	//allocate enough memory to copy of sound data
    
    	SoundData=new BYTE[LengthOfSoundWave];
    	ReadFile(MusicFile,SoundData,LengthOfSoundWave,&LengthBuffer,NULL);
    
    
    	WaveHeader=new WAVEHDR [sizeof (WAVEHDR)];
    
    
    	   waveformat.wFormatTag      = WAVE_FORMAT_PCM ;
                       waveformat.nChannels       = 1 ;
                       waveformat.nSamplesPerSec  = 11025;
                       waveformat.nAvgBytesPerSec = 11025;
                      waveformat.nBlockAlign     = 1 ;
                       waveformat.wBitsPerSample  = 8 ;
                       waveformat.cbSize          = 0 ;
    
    	   
    	   
    	   
    	   WaveHeader->lpData=SoundData;
    	   WaveHeader->dwBufferLength=LengthOfSoundWave;
    	   waveOutOpen (WaveOut, WAVE_MAPPER, &waveformat, NULL, 0, CALLBACK_WINDOW)
                                
    
    	
    	   waveOutWrite (WaveHeader, pWaveHdr2, sizeof (WAVEHDR)) ;
