Exception handler for a VO GUI application

The following code shows the exception message in a VO GUI messagebox. You should combine every exception handler with a logging functionality - a messagebox is gone too easily.

static class ExceptionHandler
static method ProcessException( oException as Exception ) as void
local cMessage as string
local oParent as object
local oBox as TextBox
	
cMessage := oException:Message
// log to disk here
do while oException:InnerException != NULL_OBJECT
  // log to disk here
  cMessage += CRLF + oException:Message
enddo
oParent := GetObjectByHandle( GetActiveWindow() )
if oParent == null_object
  oParent		:= nil
endif
oBox := TextBox{ oParent, "Error", cMessage }
oBox:Type := BOXICONHAND
oBox:Beep := true
oBox:Show()
