-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Following error is generated when you try to run the Trans.app sample
application:

  No update tables are specified. Use the Tables property of the cursor. Press
  any key to cleanup and exit...

Trans.app is a FoxPro version 2.x sample program that must be converted before it
will run in Visual FoxPro, but even after conversion, the error occurs.

CAUSE
=====

The ReadShow event handler contains a call to the REFRESH user-defined function
(UDF). Visual FoxPro now includes a built-in function by the same name that
takes precedence over the UDF.

RESOLUTION
==========

Modify the converted application, or revert to the 2.x version, make the
modifications there, and reconvert.

To modify the 2.x version of Trans.pjx:

1. Start FoxPro version 2.x.

2. Type the following command in the Command window:

  " MODIFY SCREEN Trans.scx. " (without the quotation marks)

3. Double-Click the Trans_Type popup, and edit the VALID clause. Change this
  line:

        = refresh()

  to this line:

        = myrefresh()

4. Open the Cleanup/Procs code snippet. Rename the REFRESH function in the
  Cleanup code to MYREFRESH.

5. Open the Read Show snippet. Change this line:

        = refresh()

  to this line:

        = myrefresh()

6. Close FoxPro version 2.x, and start Visual FoxPro.

7. Reconvert the application.

8. Build and run the Trans.app application.

To modify the already converted Visual FoxPro 3.0 version:

1. Start Visual FoxPro.

2. Modify the Trans.scx form. Select the frsTrans1 formset in the object popup
  of the Properties window. Click the Methods tab.

3. Edit the ReadShow method. Change this line:

        = refresh()

  to this line:

        = myrefresh()

4. Select cboTrans_Type19 in the object popup of the Properties window. Click
  the Methods tab.

5. Edit the Valid event. Change this line:

         = refresh()

  to this line:

         = myrefresh()

6. Edit the Trans.spr program from Trans.pjx. Rename the REFRESH function in
  Trans.spr to MYREFRESH.

7. Build and run the Trans.app application.

STATUS
======

This behavior is by design.
