I've successfully migrated our web apps and reports through VS2005 and VS2008 using the same login code for the Crystal report viewer (dynamic database information from web.config. We migrated to VS2012 and the same login code will work for MSSQL default instance, as well as MSSQL\SQLExpress, however it fails with the new (localDB) engine provided by MS with the following error: Failed to open the connection. Details: [Database Vendor Code: 17 ] Failed to open the connection. rptVASCodes {988AC187-9046-4B3A-B132-D32138E57C88}.rpt Details: [Database Vendor Code: 17 ] This is on a Windows 7 Pro (32), VS2012, .net 4.5 and the just released SAP Crystal Reports version for Visual Studio. Database name passed as default of (localdb)\V11.0. Any ideas would be appreciated as this is a show stopper for us at this point.
Thanks - Paul
