Using VS 2005, creating win app, I do not have neither "SqlConnection" nor "OleDbConnection" in toolbox.Why?

At first u've to add a Database to ur solution, after adding it u'll find in the toolbox "SQL connection adapter" or somethin like that. If u dunno how to add a DB to ur solution, right-click ur solution as if ur going to add a new cpp or cs file (depending on the programming language ur using) and finally choose to add a database:) Hope this helps :)
