In Microsoft Access 2000, all intrinsic constants are contained in type libraries and are visible in the Object Browser. Microsoft Access includes type libraries for Microsoft Access, ActiveX Data Objects (ADO), Data Access Objects (DAO), and Visual Basic. Each of these type libraries includes intrinsic constants.
Additionally, intrinsic constants in Microsoft Access 2000 are a mix of lowercase and uppercase, and parts of the constant are concatenated rather than separated by underscores. For example, the constant A_NORMAL in versions 1.x and 2.0 is now acNormal.
Intrinsic constants in databases created with previous versions of Microsoft Access won't automatically be converted to the new constant format, but old constants will continue to work without errors. However, it's recommended that you use the new format when writing new code.
