Step-by-Step Example

1. Create a program containing the following code:

      PUBLIC oRemoveIt
      oRemoveIt=CREATEOBJECT("RemoveIt")
      oRemoveIt.SHOW
      oRemoveIt.DOCK(0)      && This docks the toolbar on the top
   
      DEFINE CLASS RemoveIt AS toolbar
         Height = 27
         Left = 0
         Top = 0
         Width = 665
         Name = "RemoveIt"
   
         ADD OBJECT command1 AS commandbutton WITH ;
            Top = 4, ;
            Left = 6, ;
            Height = 24, ;
            Width = 24, ;
            FontSize = 8, ;
            Picture = "C:\VFP\Samples\Graphics\BMPs\Fox\Delete.bmp", ;
            Caption = "", ;
            Default = .F., ;
            ToolTipText = "Remove Objects From Active Form", ;
            Name = "Command1"
   
         PROCEDURE command1.Click
            IF TYPE('_screen.ActiveForm')=='O'
               IF NOT ISNULL (_Screen.ActiveForm)
                  =AMEMBERS(FormObjects,_Screen.ActiveForm,2)
                  FOR i = 1 to ALEN(FormObjects)
                     _Screen.ActiveForm.RemoveObject(FormObjects(i))
                  ENDFOR
               ENDIF
            ELSE
               =MESSAGEBOX("No Form is currently open.","")
            ENDIF
         ENDPROC
   
      ENDDEFINE
   						

2. Save and run the program. The result should be a single tool button on a toolbar that is docked at the top of the main Visual FoxPro window. If the tool button is clicked while a form is open, all of the form's objects will be removed.
