You can use the Controls property to reference the Controls collection of a form, subform, report or section.
Setting
The Controls property is available only by using Visual Basic and is read-only.
Remarks
Use the Controls property to refer to one of the controls on a form, subform, report, or section, within another control, or attached to another control. For example, the first code syntax would return the number of controls located on Form1. The second would reference the name of a property within a control.
Forms("Form1").Controls.Count
Forms("Form1").Controls("Textbox1").Properties(5).Name
