The SQL string: "SELECT * FROM projectTbl" will return all fields and values from that table.
Depending on what you are using to view the records: datagrid, listview etc.. and how you want users to interact with the data (i.e. allow modification of data - updating changes back to the underlying source or just read-only) will determine what type of data access objects you will use and how the data will be displayed.
If you want to display multiple records in a table-like view that allows users to directly modify the data i would recommend using a dataset object, and in your case binding this to a datagrid.
