Background Worker How To

Question

I\'m trying to implement background worker into my program, so that it wont freeze when i run the program and starts retrieving the data I need.

I\'m not quite sure

Answer 1

Background workers are threads that run in the background and do work without interrupting/blocking your main thread.

You can read more here.

In quick terms:

In DoWork do your blocking operation. Whenever you can, report how far through you are with the operation using (sender as BackgroundWorker).ReportProgress(50); for example to report 50% completion.

You can have your main thread subscribe to the "ProgressChanged" event, which can update GUI or do other tasks which should occur when the progress has changed.
