The most frequently used control is the text box, but other controls include command buttons, labels, check boxes, and subform/subreport controls. Controls let you view and work with data in your database application. Calculated control A control whose source of data is an expression, rather than a field, is called a calculated control.Ĭontrols are the parts of a form or report that you use to enter, edit, or display data. For example, a label that displays the title of a form is an unbound control. You use unbound controls to display information, pictures, lines or rectangles. For example, the criterion can be whether the user is in a certain department, or whether they are working on a certain project. Label-based access control You can use label-based access control (LBAC), an implementation of multi-level security (MLS), to control who has read access and who has write access to individual rows and columns of data.Ī security label component is a database object that represents a criterion you want to use to determine if a user should access a piece of data. When you create a label by using the Label tool, the label stands on its own-it isn't attached to any other control. This label appears as a column heading in the Datasheet view of a form. When you create a text box, for example, it has an attached label that displays a caption for that text box. When you create a label by using the Label tool, the label stands on its own - it isn't attached to any other control.Ī label can be attached to another control.
