Description Of Files Included in JetVC.exe

Directions for Use of Jet OLE DB Support Files in Visual C++

If you are using just the core OLE DB interfaces with the Jet Provider, you need to include only Msjetoledb.h in your project.

If you are using one or more of the Jet extended OLE DB interfaces (IDBUserAttributes, IIdle, or IJetCompact), you need to include Jetoledb.h as well as link your project with the Jetoledb.lib file.

If you want to use the Jetoledb.idl file with your project, you also need to include Idlmulti.h in your project. Also note that Jetoledb.idl references the Oledb.idl file installed by the Microsoft Data Access SDK 2.1. The Oledb.idl file is installed under the MDACSDK\unsupported\idl folder. Note that Oledb.idl also references other .idl files in the same folder, so for best results you should append the MDACSDK\unsupported\idl folder to your project include folders if you are using Jetoledb.idl.

The updated version of this header file can also be found with Visual Studio 6.0 Service Pack 3 (SP3). See the Readme.htm file provided with the service pack for more information. This Readme file can also be downloaded from the service pack download site at the following location:
