Controls are articles on a form or report that display data, perform actions, or enhance the object in question. Types of Controls Forms and Reports usually draw information from Tables or Queries. Forms and Reports use graphical objects called controls to link the object back to the underlying table or query. Three important controls are text boxes , frames , and labels. Text boxes display names and numbers stored in your underlying table or query.
Frames show pictures and graphs.
Labels display text as titles or other markers that describe data, but are not linked to information in the underlying table or query. Other kinds of controls, like lines and rectangles, visually organize the information and group data on-screen. This kind of control does not have a data source. You use unbound controls to enhance the presentation and clarity of your form by adding titles or descriptive labels, lines, and pictures. A text box is always a bound control.
