Unable to connect to pubs database... help!
I'm trying to connect to the pubs database (using Visual Studio 2008 and SQL Server Express), but I'm unable to for some reason, and I can't figure out why. It would help if I received some error messages, but I'm not receiving any. The program runs, but only returns a window with no data. The code below was taken from Chapter 17 of the Visual Basic 2008 book and the only code that deviates from what is found in the book is the SqlConnection constructor, so I'm inclined to believe the error is there.
I ran a different program to see if I could manually connect the database to a form, and was able to do it with no problem. Any suggestions as to what the issue could be would be greatly appreciated!!! The code is below with the SqlConnection line highlighted...
Thanks in advance for your help!
