TITLE   :PRB: Pressing ESC Key Clears Contents of Text Box in a Toolbar
PRODUCT :Microsoft FoxPro
PROD/VER:WINDOWS:3.0
OPER/SYS:
KEYWORDS:kbcode

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

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

SYMPTOMS
========

Pressing the ESC key before pressing the ENTER key when the insertion point is
in a text box, clears the content of the text box. However, doing the same thing
in a combo box does not produce the same behavior.

CAUSE
=====

The ESC key is seen as a cancel operation for a text box object. In the combo
box object, the ESC key is a terminator for the drop-down list only.

WORKAROUND
==========

In the text box object, it is possible to use the Keypress event to trap for the
ESC key. If the ESC key is pressed, a dialog box prompting the user to save the
data can be displayed. Please see the "Step-by-Step Example" section of this
article.

STATUS
======

This behavior is by design.

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

The following example creates a form with a text box, and traps for the ESC key
in the text box. When the escape key is pressed, a dialog is displayed, and if
the user answers No, the data is not cleared from the text box.

Step-by-Step Example
--------------------

1. Create a form.

2. Place a text box on the form.

3. Place the following code in the Keypress event handler:

      * Visual FoxPro Header file. This file contains named constants for many
      * Visual FoxPro functions
      #INCLUDE "FOXPRO.H"
      IF nkeycode = 27  && The escape key is pressed.
         nresponse=MESSAGEBOX("Do you want to Cancel?",  MB_YESNO)
         IF nresponse=IDNO
           NODEFAULT
         ENDIF
      ENDIF

4. Save and run the form. When the form displays, type something in the text
   box. Then press the ESC key.
