Q192576: FIX: Fix From Debugger Does Not Show VFP Desktop if Visible=.F.

Article: Q192576
Product(s): Microsoft FoxPro
Version(s): WINDOWS:5.0,5.0a
Operating System(s): 
Keyword(s): 
Last Modified: 11-DEC-1999

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

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

SYMPTOMS
========

When viewing and executing program code in the Debugger Trace Window, you can
select Debug then Fix from the Debugger menu. Normally, this closes your
currently executing program and brings up the code you were tracing in the
appropriate editor or designer. If the application you are tracing uses a Top
Level form, and the Visual FoxPro desktop is hidden with _SCREEN.Visible = .F.,
the Visual FoxPro desktop will not become visible, and the code is not displayed
in the appropriate editor or designer.

RESOLUTION
==========

To cause the Visual FoxPro desktop to display, you can do the following:

1. Type "_SCREEN.Visible" (without the quotation marks) in the Watch Window and
  then press the ENTER key.

2. Click the .F. in the Value column adjacent to _SCREEN.Visible to edit it,
  change it to .T., and then press the ENTER key.

This causes the Visual FoxPro desktop to display, and the code is now visible in
the appropriate editor.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem was corrected in Visual FoxPro 6.0
for Windows.

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

1. Make sure you have configured the Debugger to use the Debug Frame. To do
  this, from the Tools menu, select Options, and then click the Debug tab in
  the Options dialog box. The Environment drop-down list box must be set to
  Debug Frame. Note that the Debugger must be closed for this drop- down list
  box to be enabled.

2. Run the following code from a program (.PRG) file:

        PUBLIC oform
        oform=CREATEOBJECT("TL_form")
        oform.SHOW()
        READ EVENTS

        DEFINE CLASS TL_form AS FORM
           ShowWindow = 2
           AutoCenter = .T.
           lIsFormUp=.F.
           ADD OBJECT command1 AS COMMANDBUTTON WITH ;
              TOP = 180, ;
              LEFT = 80, ;
              HEIGHT = 27, ;
              WIDTH = 195, ;
              CAPTION = "Press to display Debugger", ;
              NAME = "Command1"

           PROCEDURE DESTROY
              Clear EVENTS
              _SCREEN.VISIBLE=.T.
           ENDPROC

           PROCEDURE ACTIVATE
              IF !THIS.lIsFormUp
                 _SCREEN.VISIBLE = .F.   && We wait till now to hide desktop
                    && to ensure Top Level form is active window.
                 THIS.lIsFormUp = .T.
              ENDIF
           ENDPROC

           PROCEDURE command1.CLICK
             SET STEP ON
             x = 1
           ENDPROC
        ENDDEFINE

3. Press the "Press to display Debugger" command button.

4. In the Debugger, select Debug then Fix from the menu.

5. Select Yes to cancel the program.

RESULTS: The Debugger remains displayed, and the Visual FoxPro desktop does not
reappear with program in the editor.

NOTE: You can get the Visual FoxPro desktop back by typing the following into the
Watch window, and changing its value from .F. to .T.:

  " _SCREEN.Visible" (without the quotation marks)
