Using SQL Server Data from Outlook 2000 Two ways you can incorporate SQL Server data into your Outlook 2000 solution include:  Office Web Components and Data Access Pages. Microsoft Office Web components are Component Object Model (COM) controls that you can use to publish interactive spreadsheets, charts, Microsoft PivotTable ® lists, and databases for the Web. Data access pages are interactive Web pages that maintain a live link to a host Access or SQL Server database. With this live link, users can view, edit, and manipulate data within a browser window. These components can be placed in a folder home page or an Outlook 2000 form to provide quick access to SQL Server data.  Microsoft Visual Basic ® or Visual Basic for Applications and ADO in Outlook 2000. Within Outlook 2000, you can use ADO from Microsoft Visual Basic, Scripting Edition (VBScript), Visual Basic for Applications, or a COM add-in. You can use ADO to view, manipulate, add, or delete records in a SQL Server database. Slide Objective To provide an overview of the data access tools and technologies. Lead-in There are several ways that you can use client-side data access from the Outlook 2000 client to SQL Server and Exchange Server directory data sources. Module 11: Accessing Data from the Outlook 2000 Client 3 Using the Exchange Server Directory from Outlook 2000 The Exchange Server directory contains information that you can use in your Outlook 2000 solutions. For example, you can use the objects contained in the directory to set up mailboxes or to obtain information about mail recipients. Several ways that you can access Exchange Server directory data from Outlook 2000 include:  Outlook Object Model. The Outlook object model provides objects that you can use to gain read-only access the Exchange Server address book.  CDO. The CDO Library is an interface to MAPI that provides an easy method for gaining access to the directory information stored within an Exchange Server Global Address List (GAL).  ADSI. ADSI is a set of specifications of COM objects and interfaces that you can use to manipulate Exchange Server directory services and other directory services. You can use the ADSI objects to perform common administrative operations, such as adding new users or managing a print queue. 4 Module 11: Accessing Data from the Outlook 2000 Client    Using Office Web Components  Introduction to Office Web Components  Publishing an Interactive Web Page from Excel  Using Data Access Pages  Using the Data Source Control The Office Web components are COM controls that you can use to publish interactive spreadsheets, charts, PivotTable lists, and databases for the Web.
