VB 2010 MS Access Compact and Repair Database



MS Access 2003/2007/2010 Compact and Repair

VB.Net Compact and Repair Database - MS Access

Neither ActiveX Data Objects (ADO) nor ADO .NET provide the means to compact or repair Microsoft Access databases. However, you can accomplish this task by using the Microsoft Jet OLE DB Provider and Replication Objects (JRO) that was introduced with Microsoft Data Access Components (MDAC) version 2.1. ADO .NET allows the use of COM-based object libraries through the Interop layer.

This article demonstrates how to compact an Access database by using Visual Basic .NET.

Requirements

  • Microsoft Visual Basic .NET
  • Microsoft Jet and Replication Objects 2.1, 2.5, or 2.6 Library

Steps to build example

  1. Open a new Visual Basic .NET console application.
  2. In the Solution Explorer window, right-click the References node and select Add Reference.
  3. In the Add Reference dialog box, click the COM tab, and then select Microsoft Jet and Replication Objects 2.x Library. Click Select to add it to Selected Components. Click OK.

    Note In this step, x is a placeholder for the actual version number of the Microsoft Jet and Replication Objects Library component.
  4. A warning will be displayed if there is no wrapper found for the selected library. Click Yes to generate a wrapper. Microsoft ActiveX Data Objects Library (ADODB) and JRO references will be added to the project's References.
  5. In the Solution Explorer window, right-click Module1.vb and click View Code.
  6. Delete all of the code from the code window.
  7. Copy the following code and paste it into the code window: 
  8.  

     
  1. Change the path to the Source and Destination .mdb files as appropriate. Press F5 to build and run the project.

    The compacted database will be in Access 2000 (Jet 4.0) format. For a different Jet format, see "References."

Pitfalls

In order to compact a database, the Jet Database Engine requires exclusive access to the database file. Attempting to compact a database file that is currently in use will result in an exception. This exception can be caught using a Try...Catch structure.

  1. I have better Acces Database Repair application which comes with all the major options and features with ribbon arrangement. So, there is no need to browse along the software for longer.It also repairs corrupt MS Access (.MDB or .ACCDB) database file and then recover tables, queries, forms, macros, reports, etc.
