expression Required. An expression that returns one of the objects in the Applies To list.
Setting
This property setting contains a reference to the Form object that has the focus at run time.
This property is available by using a macro or Visual Basic and is read-only in all views.
Remarks
You can use the ActiveForm property to refer to an active form together with one of its properties or methods. The following example displays the Name property setting of the active form.
Dim frmCurrentForm As Form
Set frmCurrentForm = Screen.ActiveForm
MsgBox "Current form is " & frmCurrentForm.Name
If a subform has the focus, ActiveForm refers to the main form. If no form or subform has the focus when you use the ActiveForm property, an error occurs.
