Description:
    Generate the default code for OCX events as well as PROGESS triggers.
    This function is expected to be only called for OCX controls.
    
        
Input Parameters:
    p_event    - The event.
    p_template - the type of code to generate (see list above).
    p_recid    - the RECID(_U) for the window (or dialog-box) [or widget]
 
Output Parameters:
    p_code     - the text created for this widget.
