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

ID: Q192576

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:

Type _SCREEN.Visible in the Watch Window and then press the ENTER key.

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

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.

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

Press the "Press to display Debugger" command button.

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

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
