I have no experience building a .NET desktop application, all my experience is with the web. A friend of mine has asked me to do a quick estimate for a small desktop application.
The application just displays a list of items from the database. When rows are deleted/added from the database, they need to be deleted/added from the list on the user’s desktop.
Is this done pretty easily in a desktop application, or do I need to do any sort of “reload” every X seconds?
The simplest design would involve polling the database every so often to look for new records. Adjust the number of seconds between polling to best reflect the appearance of real time and also for performance.
Any design that would allow the database management system to broadcast updates to a desktop application would be quite complicated and (depending on your needs) would most likely be overkill.
