Each iteration of Windows has meant a corresponding improvement in the techniques used for transferring data among its applications. Today's leading technique is called Automation. It allows you to work directly with objects in an application's interface using their object models. But if you want to write code in a programming language, such as Visual Basic, in order to work with the apps that support Automation, you must understand the inner workings of an application's object model--or in the case of Microsoft's Access, its two-object models. Microsoft Access is the bestselling stand-alone relational database program for Windows offering both power and ease of use. And in many respects, Microsoft has made Automation the centerpiece of its vision for application development. DAO Object Model: The Definitive Reference will guide you through the Access object models, allowing you, with the support of Automation, to reference the application components you want to manipulate. An understanding of the object models is essential for developers who work with data in Access tables, or who want to manipulate components of the Access interface from other Office apps.
The Data Access Objects (DAO) model is used to write and read data in Access tables. The Access object model is used to manipulate forms, reports, queries, macros, and other components of the Access interface, including most of the commands by means of the DoCmd object. This book includes an introduction and a brief description of the differences between VBA (used in most Office applications) and VBScript (used in Outlook). This chapter will also cover Office utilities and add-ons helpful in writing and debugging code, such as the Object Browser, the Integrated Development Environment (IDE) for VBA and the Interactive Debugger for VBScript. The book will then be divided into two parts; one covering the Access Object Model and the other, the Data Access Objects. Each section will have a description of what the object represents; listings of properties, events, and methods; and one or more code samples illustrating its use in VBA and/or VBScript code. Each property, event, or method section will have an explanation of the language element, and many will have code samples (either VBA or VBScript) as well.
The book details, to an advanced user or keen intermediate user, the Access object models and how they are used.

Helen Feddema grew up in New York City. She was ready for computers when she was 12, but computers were not ready for her yet, so she got a B.S. in philosophy from Columbia and an M.T.S. in theological studies from Harvard Divinity School, while working at various office jobs. It was at HDS that she got her first computer, an Osborne, and soon computers were her primary interest. She started with word processing and spreadsheets, went on to learn dBASE, and did dBASE development for six years, part of this time as a corporate developer. After being laid off in a flurry of corporate downsizing, she started doing independent consulting and development, using dBASE, ObjectVision, WordPerfect and Paradox. Always looking for something new and better, Helen beta tested Access 1.0, and soon recognized that this was the database she had been looking for ever since Windows 3.0 was introduced and she saw the gap waiting to be filled by a great Windows database. Since then she has worked as a developer of Microsoft Office applications, concentrating on Access, Word, and Outlook. Helen coauthored Inside Microsoft Access, (New Riders, 1992), and wrote two books for Pinnacle's "The Pros Talk Access" series, Power Forms and Power Reports (1994). She also coauthored Access How-Tos for the Waite Group Press (1995), and more recently contributed to The Microsoft Outlook Handbook (Osborne-McGraw-Hill), Que's Special Edition: Using Microsoft Outlook 97 (1997), Office Annoyances (O'Reilly, 1997), and Outlook Annoyances (O'Reilly, 1998). She also contributed chapters to Que's Special Edition: Using Microsoft Project 98 (1997) and Teach Yourself Project (1998). Most recently, Helen co-authored Sybex' MCSD: Access 95 Study Guide (1998). She has also been a regular contributor to Pinnacle's Smart Access and Office Developer journals, Woody's Underground Office newsletter, PC Magazine's Undocumented Office and the MS Office and VBA Journal. She recently contributed articles on Menu Manager and Outlook Automation Access add-ins and Access-Word data merging to Smart Access, as well as writing the Access Archon column for the Woody's Office Watch e-zine. Helen is a big-time beta tester, sometimes having 7 or 8 betas running at once, mostly Microsoft, but with some from other vendors as well. She lives in the mid-Hudson area of New York state, with three cats and three computers. Helen maintains a Web page (www.ulster.net/~hfeddema) with a large selection of code samples concentrating on connecting Access, Outlook, Word and Excel. She is an MVP on the WOPR Lounge, a threaded discussion group devoted to Microsoft Office.
