CLSID_DVBSLocator2 defined anywhere?

Question

Hello,

I'm using VS2008 + Windows SDK 7.0

I got following error compiling this:

CComPtr<IDVBSLocator2> pDVBSLocator2;<br/>
hr = pDVBSLocator2.CoCreateInstance(CLSID_DVBSLocator2);<br/>
if (FAILED( hr)) return hr;<br/>
hr = pDVBSLocator2->put_DiseqLNBSource(DiseqLNBSourceVal);<br/>
if (FAILED( hr)) return hr;

error C2065: 'CLSID_DVBSLocator2' : undeclared identifier

It was not defined in Tuner.h.....

Any idea would be greatly appreciated.

Answer 1

What makes you think CLSID_DVBSLocator2 exist at all?

Answer 2

Hi Roman, To be honest, I had no clue. I was going through a DVB-S sample and the codes were like this:

CComPtr pDVBSLocator;
hr = pDVBSLocator.CoCreateInstance(CLSID_DVBSLocator);
if (FAILED( hr)) return hr;
hr = pDVBSLocator->put_CarrierFrequency(Frequency_kHz);
if (FAILED( hr)) return hr;
hr = pDVBTuneRequest->put_Locator(pDVBSLocator);
if (FAILED (hr)) return hr;
 hr = pITuner->put_TuneRequest(pDVBTuneRequest);

So I thought for DVB-S2 there would be a CLSID as well.....

Thanks for the reply

Answer 3

I'd try querying DVB-S Locator for this interface:

CComPtr<IDVBSLocator2> pDvbSLocator;
HRESULT nResult = pDvbSLocator.CoCreateInstance(CLSID_DVBSLocator);

I think this has chance to work out, and with Windows 7 only as documentation states.
