How to get Programs from IGuideData?

[silenceboy]

I use VC6++, DX9.0b, DVB-T card.

I can get Services through GetServices() and GetServiceProperties() of IGuideData.
There are many samples about what is in IEnumGuideDataProperties about sevice info.

I think I should also get programs info throught GetProgramProperties().
However, there is no much info about what is in IEnumGuideDataProperties about program info.

Does anyone know the details about those IGuideDataProperty got from IEnumGuideDataProperties for program info?

Thx!

Solved, I found sample code, that shows how to use data from GetServiceProperties().
Actually, MSDN already said, but I ignored them before.
