iQualityControl Notify Error

Hard coded break point

"IQualityControl::Notify not over-ridden from CBasePin. (IGNORE is OK)"
At line 2346 of C:\DXSDK\Samples\C++\DirectShow\BaseClasses\amfilter.cpp

Solution :

This Error is displayed at runtime in a filter graph. So

for This Error I added the code as follows :
HRESULT Notify(IBaseFilter *pSelf,Quality q ) { return S_OK;}


in classes derived from CBasePin, Now it is working well...
