When you build you SQL insert string instead of somthing like
SQL = "INSERT INTO MyTable (Lastname, firstname) VALUES ('Andrew', 'Duff')"
You replace the values with the following based on 2 textboxs
SQL = "INSERT INTO MyTable (Lastname, firstname) VALUES ('" & Textbox1.Text & "', '" & Textbox2.Text & "')"
Hope this helps
