Some programs which use dBase as their back-end support often require the users to have a direct interaction with the DBF file. But these DBF files are easily prone to corruption. Improper saving of files is one of the major reasons behind DBF corruption. However, several new features have been included in Fox Pro and other development platforms to avoid any such type of corruption, sometimes it is difficult to trace the real cause of corruption. Corruption causes restructuring of the data present in the DBF file, which makes it unrecognizable to the database management system. To overcome such data loss instances, you need to go for DBF recovery through a reliable third-party utility.

Lets consider a scenario. Suppose, you are developing a web-based application using the ASP.NET technology. The application uses dBase III as its back-end. It has a login form wherein the customers are required to sign in by providing their respective user-id and password. The following error message may appear while a customer attempts to login to your website:

“ERROR [42S02] [Microsoft][ODBC Visual FoxPro Driver]File 'table.dbf' does not exist.”

Cause:

The following reasons may be responsible for the above error message-
The ASP.NET application do not has permissions to access the DBF table specified in the error message. The table might be present on a remote server
The DBF file may be corrupt.

Corruption in a DBF file may occur due to damaged headers, virus infections, application bugs etc. All these reasons could make your DBF file inaccessible and may cause subsequent data loss. You can use a backup to repair corrupt DBF file and restore all its valuable data. If the backup is not there, you should follow the below mentioned steps.

Resolution:

To resolve the above problem you need to take help of a third-party DBF repair tool. These software are safe and reliable. They allow you to choose the root database application and the respective version. They repair and restore DBF database files created in various versions of dBase and MS Visual FoxPro. They are capable of recovering almost all the database components, such as table name, column name, column data type, views, indexes etc.
