I have developed a ASP.NET Web Application using the CR.NET 2008 Basic (10.5.3700.0). I am ready to use the full version of Crystal Reports 2008 so I installed the Developers Edition.I have upgraded the reports/solution using the automatic tool see attached screenshot: CrystalReports2008Solut ionConver sion.png.
The Business Objects Visual Studio Integration Manager tool shows that I am using the full runtime (12.0.2000.0).The application compiles and runs fine. However when I load a report a into the CrystalReportViewer the first time I receive the error:Value cannot be null. Parameter name: inputStringThe second time the report viewer is empty (blank) no error. I have scoured my code and the report itself and I can not find the parameter/variable inputString.
Now development started in 2007 in Visual Studio 2005 with VB.NET and over the years has been migrated to C# in Visual Studio 2008. The reports however were always targetting the CR.NET Basic runtime. I need the full version to utilize the royalty free Developer's Advantage license from SAP.I am including screenshots to illustrate the report working and not working.I can change the assembly references in the web.config from 12.0.2000.0 back to 10.5.3700.0 and the report shows up correctly again. Mlmcc:I am including the markup code from the Master Page that hosts the CrystalReportsViewer. I use a tag prefix so I am including the appropriate lines from the web.config. The first defines the tag while the second as previously established determines the assembly reference.// ASPX Page Markup // Web.Config Select all.
