Suprotim is also the founder and primary contributor to Dev Curry, Dot Net Curry and SQLServer Curry.You can download VS 2008 SP1 and Visual Web Developer 2008 Express SP1 here.Two weeks ago we shipped a patch that you can apply to VS 2008 SP1 and VWD 2008 Express SP1 that causes Visual Studio to check for the presence of an optional "-vsdoc.js" file when a Java Script library is referenced, and if present to use this to drive the Java Script intellisense engine. We've worked with the j Query team to put together a j file that provides help comments and support for Java Script intellisense on chained j Query selector methods.He is the Editor of a Developer Magazine called DNC Magazine.He has also written two EBooks 51 Recipes using j Query with ASP. 2- In additiaon, when I include the file I am getting errorrs like: " Validation (CSS 2.1): 'opacity' is not a known CSS property name in jquery-ui.css".
