Active X Event Handling

If I use an Active X control in my application that fires events, will those events be queued up so that I can respond to them one at a time. If there is a queueing effect, how deep is the queue? What happens if the queue overflows? Is there any ill effect on the Active X control if I do not respond right away to an event?

Based on the behavior I have seen, I am thinking that events are being fired as interrupts. This worries me. Anybody know what really happens?

I ask these questions because I am concerned that an Active X control I am using might go through periods where it bursts events to my application and I may not be able to respond to them all as quickly as they come in. I would like to avoid spinning a thread for each event that fires.

The events will be queued up. However, what you should do is to process them as quickly as you can. The queue can overflow. If you cannot process them quickly enough, what you should do is to save the information about the event and save that in your own queue. Then return from the event handler. When you have some time, process the information in the queue.
