My boss just asked me if i could move our .net Application from .net 2.0 to 1.1 because of most users dont have 2.0 ( cant see the reason why microsoft just didnt include 2.0 in autoupdate but well ). anyway... the application is made in VS2005 with as base language C#.

• Audio and Video Development TIMING :Using "inherit" for an animated property and more

  I have two questions: 1. Can "inherit" or "auto" be used for an animated property, If yes then, Does "style" inheritance occurs from the loaded DOM or the live DOM 2.
