VISUAL BASIC

Detailed explanation-1: -Multiple-document interface (MDI) applications enable you to display multiple documents at the same time, with each document displayed in its own window. MDI applications often have a Window menu item with submenus for switching between windows or documents.

Detailed explanation-2: -MFC makes it easy to work with both single-document interface (SDI) and multiple-document interface (MDI) applications. SDI applications allow only one open document frame window at a time. MDI applications allow multiple document frame windows to be open in the same instance of an application.

Detailed explanation-3: -MDI (multi-document interface)-allows users to simultaneously view multiple documents. SDI (single-document interface)-unlike MDI, SDI only supports a single “active” document. A classic example of an SDI interface are static tabs.

Detailed explanation-4: -MDI applications usually have a main-menu item called Window. On this menu appear standard items for cascading, tiling, and activating child windows and arranging the icons of minimized child windows. Figure 4-8 shows a typical example. Such a menu is easy to create using the support in Windows Forms.

Detailed explanation-5: -Multiple Document Interface (MDI) is a Microsoft Windows programming interface for creating an application that enables users to work with multiple documents simultaneously. Each document is in a separate space with its own controls for scrolling.

Detailed explanation-6: -Application examples. Adobe Acrobat: MDI until version 7.0 (Windows-only); SDI default in 8.0 (configurable to MDI); SDI only in 9.0; MDI (with a tabbed interface) in version 2015. Corel Wordperfect: MDI.
