APPLIES TO

  • Microsoft Visual FoxPro 5.0 Standard Edition



This article was previously published under Q168526

SYMPTOMS

In Visual FoxPro 5.0, clicking the Close button (the "x" in the upper-right corner of the form) of a Top-Level form destroys undocked toolbars. However, a docked toolbar is not destroyed. Pressing the Close button should not destroy the undocked toolbar. This happens prior to the QueryUnload event of the form and cannot be controlled by the developer.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been corrected in Microsoft Visual FoxPro version 5.0a for Windows.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Place the following code in a .prg file and run it. A Top-Level form, Myform1, with a docked toolbar appears.

          **** Program Example****
    
           PUBLIC goForm
           goForm = CREATEOBJECT("myform")
           goForm.Show()
    
           DEFINE CLASS myform AS form
             BackColor = RGB(255,255,255)
             ShowWindow = 2
             oToolbar = .NULL.
    
             PROCEDURE Activate()
               IF ISNULL(THIS.oToolbar)
                 THIS.oToolbar = CREATEOBJECT("mytoolbar")
                 THIS.oToolbar.Show()
               ENDIF
             ENDPROC
    
             PROCEDURE QueryUnload()
               NODEFAULT
             ENDPROC
           ENDDEFINE
    
           DEFINE CLASS mytoolbar AS toolbar
             ShowWindow = 1
             ADD OBJECT mybutton AS commandbutton WITH ;
              Top = 5, ;
              Left = 5, ;
              Height = 22, ;
              Width = 24, ;
              Caption = ""
    
             PROCEDURE Init()
               THIS.Dock(0)
             ENDPROC
           ENDDEFINE
    
           ****End of Code Example****
  2. While the toolbar is docked, attempt to close Myform1 by clicking the close button of the form. Since the QueryUnload contains the NODEFAULT command, the form does not close.
  3. Now, undock the toolbar and attempt to close Myform1 again by clicking the close button of the form. The undocked toolbar disappears.
