Resource Scheduling

Hi All, Looking for a Staff Scheduling App. Something very Basic as i will be building on this. I basically need a GNATT type form. Multiple Staff down the side and the ability to create tasks (Allocatiing a amount of days to the task, and grouping tasks by Project Name) and then drag and drop on the GNATT Chart. It must also have the ability to show Day, Week, Month, and 3 Month Calander views It must show tasks that have been allocated and also show tasks which have not been allocated by some means? Maybe a Red or Green Indicator? It must also show task which are overdue.. It must be written in C#. and Must use a MS Access Database for its Data. Full working code in Visual Studio C# must be supplied. For some examples, something like: [login to view URL] [login to view URL] The use of DOTNETBAR Scheduling Control would be prefared but is not essential: [login to view URL] - A Trial version is available. Cheers NDB
