KB175484 - ACC97: References That You Must Set When You Work with Microsoft Access

MORE INFORMATION

Microsoft Access includes several components, each of which supplies its own set of objects. The component's object library contains information about the component's objects and their properties and methods. The objects are available to Microsoft Access only if a reference exists for the objects in the Available References box in the References box on the Tools menu.

Microsoft Access 97 Object Library References Set by Default

The following object libraries are set by default when you install Microsoft Access 97:

The Microsoft Access 8.0 Object Library (MSACC8.OLB)

The following objects and collections are found in the Microsoft Access 8.0 Object Library:

    - Application object
    - Form object
    - Forms collection
    - Report object
    - Reports collection
    - Control object
    - Controls collection
    - Module object
    - Modules collection
    - Reference object
    - References collection
    - DoCmd object
    - Screen object

The Visual Basic for Applications Object Library (VBA332.dll)

The following objects are found in the Visual Basic for Applications Object Library:
```
    - Debug object
    - Err object
    - Collection object
					
```

The Microsoft DAO 3.5 Object Library (DAO350.dll)

The following objects and collections are found in the DAO object library:

    - DBEngine object
    - Workspace object and Workspaces collections
    - Error object and Errors collection
    - Database object and Databases collection
    - TableDef object and TableDefs collection
    - Field object and Fields collection
    - Index object and Indexes collection
    - QueryDef object and QueryDefs collection
    - Parameter object and Parameters collection
    - Relation object and Relations collection
    - Recordset object and Recordsets collection
    - Group object and Groups collections
    - User object and Users collection
    - Container object and Containers collection
    - Document object and Documents collection
    - Properties collection

NOTE: In order to ease the conversion of applications that use older objects, methods, and properties, you can use the following type libraries instead of DAO350.dll:

     DAO 2.5 type library   (DAO2532.tlb)
     DAO 3.5 type library   (DAO2535.tlb)

These type libraries define the properties and methods that DAO can use. The DAO 2.5 type library is backward compatible with earlier versions of the Microsoft Jet database engine and supports all previous objects, methods, and properties. Use this type library if you want existing DAO code to work with Microsoft Jet database engine 3.0 or 3.5 without conversion.

Microsoft Office 8.0 Object Library Reference Included in the Package

Microsoft Access 97 also includes the Microsoft Office 8.0 Object Library. This is included for users who want to work with objects provided by Microsoft Office.

The Microsoft Office 8.0 Object Library (MS097.DLL)

The following objects are found in the Office 8.0 Object Library:
```
    - CommandBar object
    - FileSearch object
    - Assistant object
					
```

Setting a Reference to Other Applications

You can also set references to object libraries supplied by other applications or components when you want to use objects in those libraries for Automation operations in Microsoft Access. The following list gives some of the applications and the object libraries that you can reference.
