Answer / indira

This goes in SDI.....

when an event occurs first the command goes to frame, frame
passes it to view, if it doesnt handle the event it passes
to document, if it also doesnt handle it again passes to
doctemplate. if it doesnt handles it returns false to
document, document returns false to view, view also returns
false to frame then frame handles the event, if not it
passes to application object, if it also doesnt handle
default window procedure will handle.
