Property Value

Type Description

Returns a Form that represents the currently active MDI child window, or a null reference (Nothing in Visual Basic) if there are currently no child windows present.


You can use this property to determine whether there are any MDI child forms open in your MDI application. You can also use this property to perform operations on an MDI child window from its MDI parent form or from another form that is displayed in your application.

If the currently active form is not an MDI child form, you can use the ActiveForm property to obtain a reference to it.
