TITLE   :FIX: Error Routine Not Called for USE Command
PRODUCT :Microsoft FoxPro
PROD/VER:WINDOWS:3.0,3.0b
OPER/SYS:
KEYWORDS:kbvfp kbvfp300bBUG kbvfp500fixkbbuglist 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.

MORE INFORMATION
================

Steps to Reproduce Problem

record. Run the following program:

      SET DEFAULT TO C:\VFP\SAMPLES\DATA
      ON ERROR DO errhand WITH ERROR(), MESSAGE()

      USE customer

      ON ERROR

      PROCEDURE errhand
      PARAMETERS  errno, errmsg
