Updating Access DB in C#

I'm using C# to write a windows form application that updates an Access DB using textboxes and a button to save. I can pull in the information from the DB. My problem is when I enter values into the textboxes and click the save button, it won't update in the actual database DB. I get no errors, so I'm not understanding why it won't update it.it will chane the data base in bin directory.
