The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When printing characters to the desktop in Microsoft Visual FoxPro 6.0, the
following error might occur:

  Memory is low, streaming output updating has been disabled.

This error does not appear to occur in Visual FoxPro 3.0, 5.0, or 5.0a.

RESOLUTION
==========

In the example below, removing the @...BOX command or the SAVE SCREEN TO and
RESTORE SCREEN FROM commands prevents the error message.

Also, using @...CLEAR instead of simply using CLEAR between the RESTORE SCREEN
commands prevents the error message.

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

This error most often occurs when converting legacy code from FoxPro 2.x for
Microsoft Windows or MS-DOS into Visual FoxPro 6.0. Upgrading to Microsoft
Visual Studio Service Pack 3 does not fix the problem. In the code example
below, the @...BOX, SAVE SCREEN, and RESTORE SCREEN commands act to cause the
error. However, printing other characters or using other commands to display
data to the desktop might also cause the problem.


Steps to Reproduce Behavior
---------------------------

Create a program containing the following code and execute it:

  FOR i=1 TO 10
  @1,1 SAY ""
  SAVE SCREEN && TO scrn2
  CLEAR
  @ 5,30,5,50 BOX
  RESTORE SCREEN && FROM scrn2
  CLEAR
  RESTORE SCREEN && FROM scrn2
  @ 15,1,15,33 BOX
  ENDFOR

Note that the error mentioned in the "Symptoms" section of this article appears
repeatedly.
