I  downloaded crystal reports 2008 trial version recently and I am faced with some queries.Kindly assist me as to how I can use the html preview option.Do I also need to download RAS server?Kindly provide me some download links for it as I was unable to find any.I would also like to know whether I would also need RAS SDK for dotnet if I wish to integrate the reports designed in crystal reports 2008 with Visual studio 2005 or higher in order to allow end users to  create and modify the reports at run time.If yes,kindly provide me some links from where I can download RAS SDK for dotnet.Besides the above,any additional information   to achieve runtime creation and modification of reports is welcome.Kindly provide me  some insight into this matter at the earliest as i need it quite urgently.
