I have application in ASP.NET (C#) in which I use Sap Crystal Reports for Visual Studio. In VS everything works perfect. But when I deploy it to IIS \"Database Logon Failed\" er
Thank you everyone for your time.
I used User DSN before and I had "Failed to open the connection. Failed to open the connection 'report name'.rpt" when I deployed my application. Afterwards I changed it to SystemDSN. Previous error was gone but this time "Database Logon failed" error occured.
Finally I have solved my problem by changing connection form System DSN to Oracle Server. Everything works very well now. Consider this if you have same problem.
