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

- Microsoft Visual FoxPro for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use ToolTips with a scrollable form under Visual FoxPro 6.0, the
ToolTip positions are based upon their location at form instantiation rather
than the currently visible window.

RESOLUTION
==========

You can use the control's StatusBarText property to display ToolTip text in the
status bar at the bottom of the Visual FoxPro window (assuming you have not
turned off the screen).

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

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

1. Paste the following code into a program file:

  PUBLIC loForm

  loForm = NEWOBJECT("frmToolScroll")
  loForm.Show()

  RETURN

  **************************************************
  *-- Form:         form1
  *-- ParentClass:  form
  *-- BaseClass:    form
  *-- Time Stamp:   08/04/00 09:45:06 AM
  *
  DEFINE CLASS frmToolScroll AS form

     Top = 0
     Left = 0
     Height = 259
     Width = 273
     ScrollBars = 3
     ShowTips = .F.
     Caption = "Scrolling Form"
     Name = "frmToolScroll"

     ADD OBJECT cmdAddControls AS commandbutton WITH ;
        Top = 10, ;
        Left = 10, ;
        Height = 31, ;
        Width = 130, ;
        Caption = "Click to add controls", ;
        Name = "cmdAddControls"

     PROCEDURE Load
        *!* some initialization
        WITH ThisForm
           .AutoCenter = .T.
           .ShowTips = .T.
           .Width = 300
           .Height = 300
        ENDwith
     ENDproc

     PROCEDURE cmdAddControls.Click
        *!* lcAddControl can also be replaced with 'commandbutton'
        lcAddControl = 'label'
        lnStartX = 150
        lnStartY = 150
        
        *!* add five controls
        FOR i = 1 TO 5
           *!* calculate new control's name
           lcAddControlName = lcAddControl + LTRIM(STR(i))
           
           *!* add it
           ThisForm.AddObject(lcAddControlName, lcAddControl)
           lcAddControlName = 'ThisForm.' + lcAddControlName
           WITH &lcAddControlName
              .BorderStyle = 1
              .Caption = lcAddControl + LTRIM(STR(i))
              .ToolTipText = .Caption
              
              *!* some added controls will not be visible initially, if
              *!* starting from less than form's width & height
              .Left = lnStartX + i * 50
              .Top = lnStartY + i * 50
              
              *!* show it
              .Visible = .T.
           ENDwith
        ENDfor
        
        ThisForm.Refresh()

        *!* do it only once, or else 'controls already exists' error
        THIS.Enabled = .F.
     ENDproc
  ENDdefine

2. Run the program, and click the Add Controls button.

3. Hover the mouse over the visible labels, and note that the ToolTips appear.

4. Scroll the form, hover the mouse over the controls that are now visible, and
  note that you do not see the ToolTips appear.

5. Hover the mouse over the location where the visible labels were before you
  scrolled them, and note that the ToolTips appear.
