when I try the dataset example out in chapter 16, I was failed. because it couldn't be executed. it stoped at "myconnection.open()" the pop-up window told me like that
"An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll
Additional information: System error.

I don't know what happened,coz I used the downloaded codes...please help me!
