I am new in VB. I need to load the tables and columns of a databse into a windows form treeview. I know how to bring the information back as a dataset but all the stuff online doesn't show how to load all the tables in a database and all the columns in the the treeview as a dataset. I have to allow the person to build their SQL statment from the things they select in the treeview. I can't get the treeview working, let alone trying to work on the rest.
