UserRoles in ASP.net app

I am developing an app in asp.net (VB) where I have reached a dead end, the whole scenario is along these lines: To start with there are multiple roles there is a contract which has users assigned to it with a role, but the same user can have multiple roles on the same contract. till here its fine I can retrieve these roles , I need to store these roles and then store them into an array list. so on the main contract page then I can display the information according to the user's role privilleges.(also the roles are not in hierarchy so cant assume that what role6 has role1 will also have). I am using similiar pattern like the one in the [www.asp.net][1] starter kit (timeentry) if you see the documentation its all there([login to view URL], [login to view URL], [login to view URL]). regards ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform win xp
