"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hook up the below C++ function in your CV.
First make sure that below function get u the result I.e. length of wav file and then make DLL of it and import in your vb
DWORD GetSoundLength(LPSTR strFileName)


  CWaveFile* pWav;

  DWORD dwLen = 0;

  DWORD dwSize;



  pWav = new CWaveFile();

  if (SUCCEEDED(pWav->Open(strFileName, NULL, WAVEFILE_READ)))


    wfx = pWav->GetFormat();

    dwSize = pWav->GetSize();

    dwLen = (DWORD) (1000 * dwSize / wfx->nAvgBytesPerSec);



  if (pWav) delete pWav;
