    1. COThanks Eduardo. However, I'm not sure how this would work to solve my problem. Following the above snippet: The MyFoo instance would have to raise the above event (ProgressChanged) on the background worker, and then the event would updates the MyFoo.ProgressValue property value? The MyFoo instance can of course update its own property (as it does in the code I showed), the problem is that the ProgressBar in the UI does not update.

    2. COThanks Matthieu, I thought about using that approach but due to the frequency of update it wasn't efficient enough for my needs. I ended up using an implementation that included a dictionary mapping items to their indexes in the queue, then having a method on the queue, UpdatePosition(Item item), that looks up the items index and then bubbled it to its new position. The queue then has an event that the items register against so that they notify the queue when their priorities change. That seems to work well.

    3. COThanks Dav but this is a standard priority queue. If I add an item to the queue and it's priority is changed (outside of the queue), the order of the queue might be incorrect. In other words, a standard priority queue only sorts items when they are added to teh queue and not later. I need to implement a queue that updates as the priority of its items updates. P.S. It's not a homework problem, I need to implement this as part of some simulation software. I have some ideas of how I can implement it but want to see if there is a better way of doing it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
