    Am I calling this in the wrong order?

    Code:
    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 char[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 ;
    
    	  
    	   waveOutOpen ((HWAVEOUT*)WaveOut, WAVE_MAPPER, &waveformat, NULL, 0, CALLBACK_WINDOW);
    	   
    	  
    	   WaveHeader->lpData=SoundData;
    	   WaveHeader->dwBufferLength=LengthOfSoundWave;
    	   WaveHeader->dwBytesRecorded = 0 ;
           WaveHeader->dwUser          = 0 ;
           WaveHeader->dwFlags         = 0 ;
           WaveHeader->dwLoops         = 1 ;
           WaveHeader->lpNext          = NULL ;
           WaveHeader->reserved        = 0 ;
    
    	   waveOutPrepareHeader (WaveOut, WaveHeader,sizeof (WAVEHDR)) ;
    
    
    	
    	   waveOutWrite (WaveOut, WaveHeader, sizeof (WAVEHDR)) ;
    
    
    
    
    
    }

    It's not producing any sounds.......please help.
    There are some real morons in this world please do not become one of them, do not become a victim of moronitis. PROGRAMMING IS THE FUTURE...THE FUTURE IS NOW!!!!!!!!!

    hope some of this might help

    Have you tried
    PlaySound(sFileName,NULL,SND_ASYNC| SND_LOOP| SND_FILENAME);//play sound on loop, no msgs sent no device prep needed

    or

    filling in the flag element of the struct
    WaveHdr1.dwFlags=WHDR_BEGINLOOP|WHDR_ENDLOOP;

    this is how I did this.

    Make sure you use waveOutReset() in between sounds.
    Check for errors in the loading of sounds and devices.

    Code:
    //when you have you sound
    if(MMSYSERR_NOERROR == waveOutOpen(blah,blah,..) ) will generate a MM_WOM_ msg
    
    //In the callback handle these MM_WOM_ msgs
    
    static 	WAVEHDR 			WaveHdr1;//ensure is init to zero ie ZeroMemory()
    	MMRESULT			MMResult;
    
    //*******************************
                     case MM_WOM_OPEN:
    				if(!Sound.SoundBuffer)
        					break;//no sound ready
    
    				WaveHdr1.lpData=Sound.SoundBuffer;
    				WaveHdr1.dwBufferLength=Sound.dwDataSize;
    				WaveHdr1.dwBytesRecorded=0;
    				WaveHdr1.dwUser=0;
    				WaveHdr1.dwFlags=WHDR_BEGINLOOP|WHDR_ENDLOOP;
    				WaveHdr1.dwLoops=dRepeat;
    				WaveHdr1.lpNext=NULL;
    				WaveHdr1.reserved=0;
    				MMResult=waveOutPrepareHeader(hWaveOut,&WaveHdr1,sizeof(WAVEHDR));
    				if(MMResult!=MMSYSERR_NOERROR)
    				{
    					iError=GetLastError();
    					sprintf(sBuffer,"Failed to prepare sound file header with error#%d.",iError);
    					ThreadMessageBox(hWnd,sBuffer,Ex_ERR,MBE);//my messagebox running in its own thread
    					break;
    				}
    				MMResult=waveOutWrite(hWaveOut,&WaveHdr1,sizeof(WAVEHDR));
    				if(MMResult!=MMSYSERR_NOERROR)
    				{
    					iError=GetLastError();
    					sprintf(sBuffer,"Failed to open sound device with error#%d.",iError);
    					ThreadMessageBox(hWnd,sBuffer,Ex_ERR,MBE);
    					break;
    				}
    				return TRUE;
    				break;
    //*******************************
    //*******************************
    		case MM_WOM_DONE:
    				waveOutUnprepareHeader(hWaveOut,&WaveHdr1,sizeof(WAVEHDR));
    				waveOutClose(hWaveOut);
    			return TRUE;
    				break;
    //*******************************
    //*******************************
    		case MM_WOM_CLOSE:
    				return TRUE;
    				break;
    //*******************************

    Code:
    	ReadFile(MusicFile,&LengthOfSoundWave,4,&LengthBufferWave,NULL);
    
    	//allocate enough memory to copy of sound data
    
    	SoundData=new char[LengthOfSoundWave];
    	ReadFile(MusicFile,SoundData,LengthOfSoundWave,&LengthBuffer,NULL);
    Is this a valid memory allocation tecnique? Does it matter if Sound data is a char* or a PBYTE?



    FUNCTIONRETURN=waveOutOpen ((HWAVEOUT*)WaveOut, WAVE_MAPPER, &waveformat, NULL, 0, CALLBACK_WINDOW);

    returns "An attempt was made to load a program with an incorrect format."

    When calling WaveOutOpen I get this error.....

    "The process cannot access the file because it is being used by another process. " what does this mean?

    It means that he process cannot access the file because it is being used by another process.
    Another app is reading the file, and Windows won't let you read it. Check that there are no other apps using it, and that you haven't already opened it.
