The ADLINK HDV62A A/V Capture filter provides control of video
configuration by either property pages or access to COM inter-
faces.
3.2.1 Property Pages
The driver provides two embedded property pages. To show these
property pages, use Windows API: OleCreatePropertyFrame.

the Microsoft MSDN homepage.
Sample code for adding property pages is as follows.

ISpecifyPropertyPages *pSpecify;
HRESULT hr;
hr = pFilter->QueryInter-
face(IID_ISpecifyPropertyPages, (void **)&pSpecify);
if (SUCCEEDED(hr))
{
FILTER_INFO FilterInfo;
pFilter->QueryFilterInfo(&FilterInfo);
FilterInfo.pGraph->Release();
CAUUID caGUID;
pSpecify->GetPages(&caGUID);
pSpecify->Release();
