hi,welcome to here.
I only want to get the Device handle.what's wrong with my Code?

WAVEFORMATEX waveFormat;
    HWAVEIN hWaveIn;

    waveFormat.wFormatTag = WAVE_FORMAT_PCM;
    waveFormat.nChannels = 1;
    waveFormat.nSamplesPerSec = 11025L;
    waveFormat.nAvgBytesPerSec = 11025L;
    waveFormat.nBlockAlign = 1;
    waveFormat.wBitsPerSample = 1000;
    waveFormat.cbSize = 8;

    err = waveInOpen(&hWaveIn,1,&waveFormat,NULL,0,CALLBACK_NULL );

unsigned long nResult;
HWAVEOUT waveHandle;
WAVEFORMATEX waveFormat;

/* Initialize the WAVEFORMATEX for 16-bit, 44KHz, stereo */
waveFormat.wFormatTag = WAVE_FORMAT_PCM;
waveFormat.nChannels = 2;
waveFormat.nSamplesPerSec = 44100;
waveFormat.wBitsPerSample = 16;
waveFormat.nBlockAlign = waveFormat.nChannels * (waveFormat.wBitsPerSample/8);
waveFormat.nAvgBytesPerSec = waveFormat.nSamplesPerSec * waveFormat.nBlockAlign;
waveFormat.cbSize = 0;

/* Open the preferred Digital Audio Out device.*/
nResult = waveOutOpen(&waveHandle, WAVE_MAPPER, &waveFormat, (DWORD)myWindow, 0, CALLBACK_WINDOW);
if (nResult)
printf("There was an error opening device!");
