BUG: HalfHeight Forms Closable Even If Closable = False

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0, 5.0a

SYMPTOMS

If you create a form with a halfheight title bar and set the Closable property of the form to false (.F.), you can still close the form.

WORKAROUND

To avoid the problem, use the QueryUnload event. Put a NODEFAULT in its code to make it impossible to close the form:

   x = CREATEOBJECT( 'myform' )
   x.Show
   READ EVENTS

   DEFINE CLASS myform AS Form

     HalfHeightCaption = .t.

     Add Object cmdclose AS CommandButton
     cmdclose.Caption = "Close"

     PROCEDURE cmdclose.click
          thisform.release
     ENDPROC

     PROCEDURE QueryUnload
          NODEFAULT
     ENDPROC

     PROCEDURE Destroy
          CLEAR EVENTS
     ENDPROC

   ENDDEFINE

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
