Launching a report using RAS under VS.NET 2013



I am an experienced Crystal Reports developer and have built a very simple report using CR Developer 14. The report is designed to be used against a SQL Server database and an Oracle database. In the designer, I have no problem loading the same report, and when I run it, connecting to either the SQL Server or Oracle database.

Using the application I developed under VS.NET 2013 Professional, different story and bigger problem. Using the Crystal Reports Engine, I have no problem loading the report and displaying in the crystal reports viewer, provided I load the report first in the designer and save it for the target database. In other words, using the crystal reports engine/document objects under, I cannot dynamically set the datasource; the only logon property I cannot set is the db provider! Thus I am stuck.

However I have been told that the Report Application Server can dynamically set the datasource/all logon properties. But I have not been able to get a report to launch. I get the error message attached to this thread.

I do not understand what to do next; if I need to buy more Crystal components or install/configure my environment better or ?

Can someone please provide me with a list of steps/tasks I can look into that will launch this report? Again, my launch code is very simple, and it results in a very hard error that I've been grappling with all day. Please advise! Thank you.
