Office Objects and Object Models

Each Microsoft® Office XP application contains a powerful set of tools designed to help you accomplish a related set of tasks. For example, Microsoft® Access provides powerful data-management and query capabilities, Microsoft® Excel provides mathematical, analytical, and reporting tools, Microsoft® Outlook® provides tools for sending and receiving e-mail, for scheduling, and for contact and task management, and Microsoft® Word makes it possible for you create and manage documents, track versions of documents among different users, and create forms and templates. As powerful as these and the other Office applications are on their own, you also can integrate the features from two or more Office applications into a single solution to amplify and focus users' productivity.

The key technology that makes individual Office applications programmable and makes creating an integrated Office solution possible is the Component Object Model (COM) technology known as automation.

Automation makes it possible for a developer to use Microsoft® Visual Basic® for Applications (VBA) code to create and control software objects exposed by any application, dynamic-link library (DLL), or Microsoft® ActiveX® control that supports the appropriate programmatic interfaces. VBA and automation make it possible for you to program individual Office applications, as well as to run other applications from within a host application. For example, you can run a hidden instance of Excel from within Access to perform mathematical and analytical operations on your Access data. The key to understanding automation is to understand objects and object models: what they are, how they work, and how they work together.

Note   To master the use of automation in your Office solutions, you must have a detailed working knowledge of the applications you are integrating. That is the kind of knowledge and experience that can be gained only with further application-specific training and hands-on experience.
