I've build an application in Vs2005. For the dataaccesslayer i've create the dataset with the datasource tool. After that i build stored procedures for doing actions on the database. Now i want to return the error messages to my application. It's possible to give the errornumber back to the application, but i want also the error message to return F/E: Msg 8114, Level 16, State 1, Procedure DeleteStopDefinition, Line 0 Error converting data type nvarchar to int. How can i fix this?
