SUMMARY
=======

In many cases, it is best to select or highlight the full text of a field when
that field gains the focus. This allows the user to simply begin typing to
replace the original text with new text or to press TAB to leave text as it is,
and move to the next field. This is particularly useful in screens where there
are multiple text boxes bound to a Data control for example.

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

1. Start a new project in Visual Basic. Form1 is created by default.

2. Place three text boxes on the form named Text1, Text2, and Text3.

3. Add the following code to the form1 code window:

     Option Explicit

     Sub Form_Load()
        Text1_lostfocus
        Text2_lostfocus
        Text3_lostfocus
     End Sub

     Sub SetSelected(ctl As Textbox)
        ctl.SelStart = 0
        ctl.SelLength = Len(ctl.Text)
     End Sub

     Private Sub text1_LostFocus()
         Call SetSelected(text1)
     End Sub

     Private Sub text2_LostFocus()
         Call SetSelected(text2)
     End Sub

     Private Sub text3_LostFocus()
         Call SetSelected(text3)
     End Sub

4. On the Run menu, click Start or press F5. You will notice that as you move to
  each text box, the text is highlighted as opposed to the default behavior of
  the mouse pointer remaining in front of the first letter in] the text box.
