Article: Q140792
Product(s): Microsoft FoxPro
Version(s): 3.0 3.0b
Operating System(s): 
Keyword(s): kbvfp kbvfp300bBUG kbvfp500aBUGkbbuglist
Last Modified: 23-MAR-2000

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

- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b 
-------------------------------------------------------------------------------

SYMPTOMS
========

Setting the Readonly property to True for a column that contains a check box
does not prevent the check from being changed at run-time. Setting the Readonly
property of a column containing a text box to true prevents the entries in that
column from being changed at run-time.

STATUS
======

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

WORKAROUND
==========

Set the Enabled property of the column to false. The column displays but the
colors are dimmed. You can change these colors. However, the column will not
display disabledforecolor as black even with an entry of 0,0,0. The check box
also remains dimmed.

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

Steps to Reproduce Problem
--------------------------

1. Create a form, and place the Products table in the data environment of the
  form. Drag the Products table onto the form to place a grid on the form.

2. Change the grid's Columncount property to 2.

3. Make the controlsource for column1 product_id, and set the Readonly property
  to true.

4. Add a check box to column2, and make the controlsource for column2
  discontinu, which is a logical field. Set the column2 Readonly property to
  true. Change the sparse setting for column2 to false.

5. Remove text1 under column2 by selecting it in the property sheet, clicking
  the title bar of the form, and pressing the DELETE key.

6. Set the Readonly property for the grid to true.

7. Run the form. You will not be able to change the product_id in column1, but
  you will be able to select and clear the check box in column2 to change the
  field.
