FIX: Error Routine Not Called for USE Command

ID: Q129646

3.00 3.00b WINDOWS kbother kbbuglist kbfixlist

The information in this article applies to:

Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b

SYMPTOMS

Visual FoxPro will not trap for the error caused by trying to open a table that is part of a corrupted database.

Usually, the "USE customer" command will open the table and the database that the table is part of. If the Database is corrupt, the following message is displayed:

   The database for table C:\..\CUSTOMER.DBF could not be opened. Would you
   like to try to locate the owning database or delete the link (and free
   the table). Locate   Delete    Cancel

In a program with an error routine, the error routine is not called, and the above message is still displayed. Selecting Cancel ends the program.

RESOLUTION

Do not open a table that is part of a database without first opening the database. Then you can trap for the error generated by trying to open a corrupt database.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0 for Windows.
