Description
An MDI (Multiple-Document Interface) form is a window that acts as the background of an application and is the container for forms that have their MDIChild
Remarks
You create an MDI form by choosing New MDI Form from the File menu.
An application can have only one MDI form but many MDI child If an MDI child form has menus, the child form's menu bar automatically replaces the MDI form's menu bar when the child form is active. A minimized MDI child form appears as an icon within the MDI form.
MDI forms can contain only menu and picture box controls and custom controls that have an Align property. To place other controls on an MDI form, you can draw a picture box on the form and then draw other controls inside the picture box. You can use the Print method to display text in a picture box on an MDI form, but you can't use this method to display text on the MDI form itself.
An MDI form cannot be modal
Note that MDI child forms are designed independently of the MDI form, but are always contained within the MDI form at run time.
