QuestionStuck in WaveInProc Pin
AmbiguousName2-Feb-13 7:21
AmbiguousName2-Feb-13 7:21 
Hello guys. I am trying to write a small recording program but am stuck in basics. I can not pass the pointer of the WaveInProc function properly. I am trying it in two ways, both of them widely used on online examples.
1 - rResult = ::waveInOpen(&phWaveIn, WAVE_MAPPER, &pcmWaveFormat, (DWORD)WaveInProc, 0, CALLBACK_FUNCTION);

2 - rResult = ::waveInOpen(&phWaveIn, WAVE_MAPPER, &pcmWaveFormat, (DWORD)&WaveInProc, 0, CALLBACK_FUNCTION);

// then tried this one as well, generating error c2440
3 - rResult = ::waveInOpen(&phWaveIn, WAVE_MAPPER, &pcmWaveFormat, (DWORD)(VOID*)WaveInProc, 0, CALLBACK_FUNCTION);

Their corresponding error messages are shown as under
1 - error C2440: 'type cast' : cannot convert from 'void (__stdcall CWaveApiDlg::* )(HWAVEIN,UINT,DWORD,DWORD,DWORD)' to 'DWORD'

2 - error C2276: '&' : illegal operation on bound member function expression

This is what WaveInProc looks like in my .cpp file
void CALLBACK WaveInProc(HWAVEIN hDevice, UINT uMsg, DWORD dwInstance, DWORD dwParam1, DWORD dwParam2)
{
}

Everything seems to be fine ... what is wrong here? Thanks for any help.

This world is going to explode due to international politics, SOON.
