What is the necessity of using Application.DoEvents and when we should use it?
Application.DoEventsis usually used to make sure that events get handled periodicaly when you’re performing some long-running operation on the UI thread.A better solution is just not to do that. Perform long-running operations on separate threads, marshalling to the UI thread (either using
Control.BeginInvoke/Invokeor withBackgroundWorker) when you need to update the UI.Application.DoEventsintroduces the possibility of re-entrancy, which can lead to very hard-to-understand bugs.
