Answer 1

You have to escape double quotes (") in string with double double quotes( "" ).

Try this

Dim sqlString As String = "Data Source=.\SQLEXPRESS; AttachDbFilename=""c:\users\cj\documents\visual studio 2010\Projects\WindowsApplication1\WindowsApplication1\cj.mdf"";Integrated Security=True;User Instance=True"
