Checks for the existence of records.

The CheckBorders method is a virtual method used to check for the existence of records after the FormVCR class has completed an update.

The CheckBorders method is called from the UpdateWindow, ResetSort, TakeRequestChanged methods, and set a number of private properties used to control the display state of the FormVCR controls.

Example:

 

FormVCRClass.UpdateWindow PROCEDURE

 CODE

   IF ~(SELF.Sort.Locator &= NULL)

     SELF.Sort.Locator.UpdateWindow

   END

   SELF.CheckBorders

   SELF.UpdateButtons

   IF ~SELF.Toolbar &= NULL

     SELF.Toolbar.DisplayButtons

   END
