Q171983: PRB: SelectOnEntry Property Does Not Highlight Single Character

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

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When setting the SelectOnEntry property in Visual FoxPro 5.0 to True (.T.), a
single character is not highlighted when the object receives focus with some
objects.

Of all the objects in Visual FoxPro 5.0 that use the SelectOnEntry property, the
TextBox and ComboBox are the ones that do not highlight a single character
properly. The EditBox, Spinner, and Grid column objects highlight a single
character properly. If any of the object just mentioned has more than one
character in it, then the characters are highlighted properly when the
SelectOnEntry is set to True.

The same problem occurs when using the "K" setting in the Format property of the
TextBox or ComboBox. Setting the Format property to "K" selects all text when
the object receives focus. The SelectOnEntry property was not available in
Visual FoxPro 3.0. The Format property value of "K" works properly with just one
character in Visual FoxPro 3.0 and, therefore, the workaround below is not
necessary. The ComboBox in Visual FoxPro 3.0 does not have a Format property or
the SelectOnEntry property.

RESOLUTION
==========

To allow a single character to become highlighted in a TextBox or ComboBox,
check the length of the value to see if it is a single character. If it is only
one character in length, using the KEYBOARD command allows the character to be
highlighted. Place the following code into the Gotfocus event:

     IF LEN(ALLTRIM(THIS.VALUE)) = 1 && Use This.Value works for
     *                                  textboxes,
        KEYBOARD '{shift + home}'    && and This.DisplayValue for
     *                                 Comboboxes.
        KEYBOARD '{shift + rightarrow}'
     ENDIF

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. We are researching this problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.

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

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

1. Create a form and place a TextBox, ComboBox, and EditBox on the form.

2. Change the SelectOnEntry property to True for each of the objects.

3. After running the form, type one character into each of the objects. Tab
  through the objects and note that the single character in the EditBox is the
  only character that gets highlighted.

4. Type more than one character into each of the objects and tab through the
  objects. Note that the characters in each object gets highlighted properly.
