Finding Client Machine Capabilities using Flex / Flash

In my current project Flipbook, we needed to tackle with the resolution settings on the Client side.

After googling for a while, we came to know about a very handy API from Action Script 3.0 named Capabilities. Many importent  system setting on Client machine can be viewed using it which includes …

• System Resoultions
• Operating System
• Version
• Player Type
• Audio Capabilities
• Video Encouder

Using various properties for Capabilities class, you can determine different client side settings in your application. For ex. I needed to set the  browser resolution based on the Current Client Resolution settings. Certainly it’s preety good to know this API.
