If I write this: CComPtr<IBaseFilter> pSobel;

The first error of my program is this one:

Did you try Google?

First match for "ccomptr site:microsoft.com":

http://msdn2.microsoft.com/en-us/library/ezzw7k98.aspx

Shows you need to #include <atlbase.h>

If you don't know how to fix such basic errors, IMO, you are tackling a
project that is beyond your abilities.

Also, the CComPtr suggestion is on my site (though I reference <atlcom.h>
instead of <atlbase.h>):
