Q172088: FIX: SelText in Edit Box Limited to 255 Characters

Article: Q172088
Product(s): Microsoft FoxPro
Version(s): MACINTOSH:3.0b; WINDOWS:3.0,3.0b,5.0,5.0a
Operating System(s): 
Keyword(s): kbcode
Last Modified: 23-MAR-2000

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

- Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a 
- Microsoft Visual FoxPro for Macintosh, version 3.0b 
-------------------------------------------------------------------------------

SYMPTOMS
========

In Visual FoxPro 3.x and 5.x for Windows and Visual FoxPro 3.0b for the
Macintosh, the SelText property for an Editbox selects only up to 255
characters.

RESOLUTION
==========

The workaround is to use the SUBSTR function as illustrated below:

     SelectedText = SUBSTR(ThisForm.edit1.Value, ;
                           ThisForm.edit1.SelStart + 1, ;
                           ThisForm.edit1.SelLength)

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This has been corrected in Visual FoxPro 6.0.

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

1. Create a program with the following code:

        PUBLIC x
        x=CREATEOBJECT('form1')
        x.Show

        DEFINE CLASS form1 AS form

           Top = 0
           Left = 0
           Height = 250
           Width = 425
           DoCreate = .T.
           Caption = "Form1"
           Name = "Form1"

           ADD OBJECT edit1 AS editbox WITH ;
             Height = 229, ;
             Left = 11, ;
             Top = 10, ;
             Width = 276, ;
             Name = "Edit1"

           ADD OBJECT command1 AS commandbutton WITH ;
             Top = 25, ;
             Left = 300, ;
             Height = 27, ;
             Width = 84, ;
             Caption = "Click Me", ;
             Name = "Command1"

           PROCEDURE edit1.Init
             This.HideSelection = .F.
             This.Value = REPLICATE( "abcedfghijklmnopqrstuvwxyz", 15 )
             This.SelStart = 0
             This.SelLength = LEN( This.Value )
           ENDPROC

           PROCEDURE command1.Click
             =MESSAGEBOX("SelLegth "+STR(Thisform.edit1.SelLength))
             =MESSAGEBOX("SelText "+STR(LEN(Thisform.edit1.SelText)))
             =MESSAGEBOX(Thisform.edit1.SelText)
           ENDPROC

        ENDDEFINE

2. Run the .prg file and click the CLICK ME button.

The second message box shows only 255 characters for the SelText property instead
of 390.
