Game Programming and Event Handlers

I haven't programmed games for about 10 years (My last experience was DJGPP + Allegro), but I thought I'd check out XNA over the weekend to see how it was shaping up. I am fairly impressed, however as I continue to piece together a game engine, I have a (probably) basic question. How much should you rely on C#'s Delegates and Events to...

How do I connect to a USB webcam in .NET?

I want to connect to a USB Webcam in .NET, specifically using C#. Being new to .NET I don't know what kind of support there is in the standard libraries for doing so.

Full Resolution Camera Access in j2me

I'm trying to do an image capture on a high end Nokia phone (N95). The phone's internal camera is very good (4 megapixels) but in j2me I only seem to be able to get a maximum of 1360x1020 image out. I drew largely from this example http://developers.sun.com/mobility/midp/articles/picture/ What I did was start with 640x480 and increase...

Extended Camera control on Windows Mobile

Hi, I know how to capture a camera snaphot on Windows Mobile 5.0/6 using SHCameraCapture. But is there something more extensive that allows me much finer control? Namely to get available zoom levels and to set the zoom level programmatically, also e.g. different ISO modes / lightsensitivity and setting of macro mode if available. (I.e. ...

I know that I can access the camera or show the image picker to the user, but what if I just wanted to pick 10 photos, randomly, from the images stored on the device with no user interaction?

Android : Getting file name from camera?

I have run into a small issue with something that I am probably just overlooking. I want to take a picture from the surface preview of the camera, and save it to the sd_card.

How can you programmatically control a Casio Exilim EX-F1 digital camera?

I would like to be able to programmatically emulate a shutter button press on my Casio Exilim EX-F1 digital camera.
