#1 It depends on the reason if you need a separate control object.
If not - the base T3D camera is your way.
If you need it - you choose one of the camera systems and port it.
The last way is to write up your own camera system.

If you need a fixed camera like the old Resident Evil games, you need a separate control object and a simple look at controller.

#3 What version of Visual Studio are you using? If you're using the express version, you can't compile ActiveX controls, since ATL is not included.

#4 -

#5 Do you need the web plugin? If not, just remove it.
Otherwise, yes, you will need to upgrade to at least the Standard Edition: http://store.microsoft.com/microsoft/Visual-Studio-2008-Standard-Edition-Upgrade/product/99E69042

And since you have express, you actually do qualify for the upgrade version.

#6 Hey I would be really interested in the port code if you wouldn't mind putting it up as a resource and linking to it. I am sure others would as well.

I used a heavily modified version a long time ago and since they Tomas and others made quite a few updates to it and have just started looking at porting it, but if you have it up no since in redoing the work.
