hi friend, Open a new Visual Basic .NET console application. In the Solution Explorer window, right-click the References node and select Add Reference . 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. 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 . In the Solution Explorer window, right-click Module1.vb and click View Code . Delete all of the code from the code window. Here is the code Copy and paste it to your module: Module Module1 Sub Main() Dim jro As JRO.JetEngine jro = New JRO.JetEngine() jro.CompactDatabase("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:
wind.mdb", _ "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\NewNwind.mdb;Jet OLEDB:Engine Type=5") MsgBox("Finished Compacting Database!") End Sub End Module Change the path to the Source and Destination .mdb files as appropriate. Press F5 to build and run the project. You can change the providers if you want it to higher versions. The compacted database will be in Access 2000 (Jet 4.0) format. Please mark as answer if it helps
