How to make the cleanest code when reporting progress to a user?

Question

I\'ve struggled for the last couple of months to come up with some clean code to report progress to a user. Everything always seems to boil down to:

ReportProgr         


        

Answer 1

set up your tasks as an event stream, and have the event-processing 'engine' report progress. Each event instance can have its own name, progress-reporting blurb/template, etc. if you want to go that far

if this is a pattern that occurs often, it is worth the effort for the infrastructure. When you're done, the usable code might look something like:

EventQueue tasks = new EventQueue();
tasks.Add(new TaskEvent(this.doTask1,"Foo-ing the bar"));
tasks.Add(new TaskEvent(this.doTask2,"Bar-ing the foo"));
tasks.Add(new TaskEvent(this.doTask3,"Glitching and whinging"));
...
tasks.Execute(this.ProgressEventHandler);
