DAO: Where Is...

OverviewHow Do IFAQSampleODBC Driver List

This article will help you locate topics of interest in the MFC DAO documentation and in the DAO Help topics. This article is organized as follows:

  • DAO Overviews

  • DAO Objects

  • Information By Topic

  • Key DAO Help Topics

Documentation for the MFC DAO classes consists of two components:

  • MFC-specific: MFC classes in the Class Library Reference and MFC encyclopedia articles in Visual C++ Programmer’s Guide. The articles all begin with the “DAO” prefix.

  • DAO-specific: Topics from the DAO Help files shipped with products such as Microsoft Office. These topics have been incorporated into the online documentation, but note that they are oriented toward the Basic programming language. They are included to provide DAO-specific details in areas where MFC neither modifies nor adds to DAO functionality.

DAO Overviews

For overviews and general information about MFC DAO, see:

DAO Objects

DAO consists of a number of objects. Here’s where to find information about each object type:

Where to find information about DAO objects

Querydef Object DAO Querydef
Recordset Object DAO Recordset
Tabledef Object DAO Tabledef
Workspace Object DAO Workspace

See Also   DAO Database: Using Workspaces and Databases, DAO: Creating, Opening, and Closing DAO Objects, DAO: Accessing Implicit MFC DAO Objects, DAO External: Working with External Data Sources, DAO Queries, DAO Record Field Exchange (DFX)
