It takes a little while getting used to, especially if you've
never used message boards before - but it shouldn't be *too*
bad.

That's one of the problems with having limited space available,
iirc attachments are auto-pruned after a while. But if you look
naer the bottom of that thread, you will see a post from Scronty
containing this: http://www.scrontsoft.com/win32asm/webcamapp.zip

Webcam stuff might not be the easiest to interface with; never
looked at the APIs myself, so it's just a guess.

There's a whole couple of things you'll need to look into, I
guess. One would be the APIs for interfacing with webcams.
Then there's how file I/O works in win32 (pretty easy, but since
the win32 api is very flexible, there are a lot of parameters
and such). And then of course there's dealing with bitmap files.
Topics that aren't too bad taken one by one, but quite a
mouthfull if you start from scratch and want to do it all :)

Closed-source 'shell' without terribly good documentation? Ach!
If your camera follows the windows standards (ie., isn't 5+ years
old or worse), then you can probably dump the logitech SDK and
just use the Windows APIs, unless you want to do something very
specific.

Getting the PlatformSDK is a smart idea, but if you aren't on
broadband you can always use the online version at
http://msdn.microsoft.com/ ("search MSDN for").
