Regards the Timed Camera Capture sample I posted last month, lots of you came across a bug in my code that slipped through my rigorous testing. I did a little code tidy up before I posted the ZIP and inadvertently removed an important line from the graph setup steps. Of course I tested it thoroughly before posting but its never a good thing to test your own code!
Anyway I have updated the ZIP file and posted over the top of the old ZIP. Here is the link: http://marcusperryman.members.winisp.net/BlogStuff/TimedCamera.zip
The error was in CGraphManager::CreateCaptureGraphInternal() where the filter graph is initially built. To make sure you have the right ZIP its 46.7kb (reported by explorer download window).
We apologies for the inconvenience.
