Article: Q159269
Product(s): Microsoft FoxPro
Version(s): WINDOWS:5.0
Operating System(s): 
Keyword(s): kbvfp600fix
Last Modified: 24-MAR-2000

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

- Microsoft Visual FoxPro for Windows, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Visual FoxPro 5.0 causes a General Protection Fault (GPF) when the caption
property of a Label is set more than 255 characters.

WORKAROUND
==========

Set the caption property of a Label to something less than 255 characters.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

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

This behavior happens only in Visual FoxPro 5.0; it works as expected in Visual
FoxPro 3.0 or 3.0b.

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

1. Create a Form and place a Label on it.

2. In the INIT method of the form, put in the following code:

        ThisForm.Label1.Caption = Replicate("X",256)

3. Save and run the form.

NOTE: Visual FoxPro terminates immediately when the form runs. (Generally the
fault is an "Invalid Page Fault.")
