I am very novice when it comes to programming , but I am employed with the task of getting an ASP website running. I have been able to overcome several obstacles, but I cannot figure this part out. I need to know if these paths are causing an error, as this was coded in a different environment and the drive letter 'E' does not exist here, which I imagine they are attributing to some errors, and where can I find the code to modify or remark them out?? This is the error I receive: Object reference not set to an instance of an object. Source File: c:\inetpub\wwwroot\******\index.aspx Line: 8 Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] US.SqlHelper.SqlHelper.get__connectionString() in E:\2011项目_LXZ\春风动力项目\春风动力\å¼€å‘\trunk\CFMT\Source\US.
