When we handle SSIS events using IDTSEvents callbacks as described here, will it in any way affect the event handlers already in that package? Eg will it override the existing package?

Why there is such a concern, frankly I do not understand how it could override the package itself? I am not sure what you built, but my understanding the events get processed as they occur, all depends what you placed into the event handlers.Arthur My Blog

Basically, the app I am writing loads a SSIS package which could be built by different third parties. My code is only supposed to load and execute it. What I also want is to report progress of its execution, hence the need to programatically hook into OnProgress event of the package. Since the package itself may implement OnProgress event handler, I was wondering if implementing the OnProgress event programatically will interfere in any way with the existing OnProgress event handler of the package?
