SUMMARY

This article describes the Microsoft Jet 2.0/Visual Basic 3.0 Compatibility Layer that allows owners of Microsoft Access 2.0 and Visual Basic 3.0 to use and create Jet 2.0 databases in Visual Basic 3.0.

MORE INFORMATION

How to Obtain the Compatibility Layer

To obtain the Compatibility Layer, choose one of the following methods:
The Compatibility Layer that you download from the MSL or that is included in the ODK does not include the Microsoft Access version 2.0 (Jet 2.0) database engine file. The 2.0 database engine comes with Microsoft Access or the ADT. Therefore, to use the Compatibility Layer, you need to purchase Microsoft Access version 2.0 or the ADT. The license in the ODK permits distribution of this file with Visual Basic version 3.0-based applications. Suggested retail price for Microsoft Access version 2.0 is $495. Until August 31, 1994, current Microsoft Access version 1.x users can upgrade for $99. And those users upgrading from competing products and from Microsoft Office can purchase Microsoft Access version 2.0 for $129.

How to Distribute the Compatibility Layer

After obtaining the Compatibility Layer from any of the options listed above, Microsoft allows propagation of the Compatibility Layer files free- of-charge to other eligible Visual Basic licenses within the same organization.

Applications created with Visual Basic and the Microsoft Access version 2.0 (Jet 2.0) database engine are, as before with Microsoft Access version 1.1, fully distributable royalty-free to application end users. The following files may be distributed with your Visual Basic applications:
MSAJT200.DLL  -- The Microsoft Access 2.0 database engine
MSAJT112.DLL  -- The Microsoft Access 2.0 compatibility layer.
VBDB300.DLL   -- Microsoft Visual Basic to Access support DLL.

BTRV200.DLL   -- Btrieve ISAM driver library.
PDX200.DLL    -- Paradox ISAM driver library.
XBS200.DLL    -- Microsoft FoxPro ISAM driver library.

PDBJET.DLL    -- Crystal Reports file.
PDCTJET.DLL   -- Crystal Reports file.
PDIRJET.DLL   -- Crystal Reports file.
