I am trying to work on this work in the VB.NET book in this chapter called " Accessing Database Files." the instructions call for a DataGridView control on the form and to click the smart tab arrow. When selecting add project data source from the drop down, it activates the data source configuration wizard. It then calls for clicking on database and selecting new connection which then asks to select the Microsoft SQL Server Database file (SQL Client). We then have to browse for the RnRBooks.mdf file and then test the connection from anywhere it is available but I cannot test my connection to continue, even from the CD. What can I do to fix this?
