WinSDK function WinBioCaptureSample always return E_NOTIMPL with MS sample RRS feed

  • Question

  • Hi

    I am trying to call function WinBioCaptureSample but it always return E_NOTIMPL, all other functions of biometric are working well.

    in event viewer i can see this same error

    "The Windows Biometric Service failed to export data from sensor: Synaptics UWP WBDI SGX (USB\VID_06CB&PID_00BE\B45D3E005FB5)"

    I am using microsoft sample code without any change.

    hr = WinBioOpenSession(
    WINBIO_TYPE_FINGERPRINT,    // Service provider
    WINBIO_POOL_SYSTEM,         // Pool type
    WINBIO_FLAG_RAW,            // Access: Capture raw data
    NULL,                       // Array of biometric unit IDs
    0,                          // Count of biometric unit IDs
    WINBIO_DB_DEFAULT,          // Default database
    &sessionHandle              // [out] Session handle
    );
    if (FAILED(hr))
    {
    wprintf_s(L"\n WinBioOpenSession failed. hr = 0x%x\n", hr);
    goto e_Exit;
    }


    // Capture a biometric sample.
    wprintf_s(L"\n Calling WinBioCaptureSample - Swipe sensor...\n");
    hr = WinBioCaptureSample(
    sessionHandle,
    WINBIO_NO_PURPOSE_AVAILABLE,
    WINBIO_DATA_FLAG_RAW,
    &unitId,
    &sample,
    &sampleSize,
    &rejectDetail
    );

    here hr is always E_NOTIMPL

  • Did you try some other arguments for WinBioCaptureSample?

    By the way, since this does not seem Visual Basic, maybe you repost it to an appropriate forum?
