You can use the ControlType property in Visual Basic to determine the type of a control on a form.
Note The ControlType property applies only to controls on a form.
The ControlType property setting is a constant corresponding to an Integer value that specifies the control type.

| acRectangle | 101 | Rectangle |
| acLine | 102 | Line |
| acImage | 103 | Image |

The ControlType property can only be set using Visual Basic in form Design view but can be read in all views.
The ControlType property is useful not only for checking for a specific control type in code, but also for changing the type of control to another type. For example, you can change a text box to a combo box by setting the ControlType property for the text box to acComboBox while in form Design view.
You can use the ControlType property to change characteristics of similar controls on a form according to certain conditions. For example, if you don’t want certain users to edit existing data in text boxes, you can set the SpecialEffect property for all text boxes to Flat and set the form’s AllowEdits property to No. The SpecialEffect property does not affect whether data can be edited; it is used here to provide a visual clue that the control behavior has changed.
The ControlType property is also used to specify the type of control to create using the CreateControl function.
CreateControl, CreateReportControl Functions.
See the AllowAdditions property example.
