# UI Threading Helper Classes

By Roy Osherove May 17, 2003 In [.Net Original](https://osherove.com/blog/category/net-original)

**Historical article** · Originally published May 17, 2003; technical details may be outdated.

Following up on my post about how [UI threading sucks](http://dotnetweblogs.com/rosherove/posts/6554.aspx) , and [Julie's post](http://dotnetweblogs.com/jlerman/posts/6562.aspx) about the subject (Julie or Julia? which is it?), I've decided to create some helper classes for working with UI threads. Meet **UIThreadHandler** and **UIThreadManager**.

Basically, they save you a lot of time by saving you the trouble of creating method stubs which call Invoke() on the form (which is what you need to do when getting events from a separate thread).

You can read all about them and how to use them - [here](http://dotnetweblogs.com/rosherove/story/7171.aspx), or you can just [download the code](http://www.codeproject.com/useritems/VSNetRegHelper/UIManager.zip) and look.

**but here's a taste**: This is all I need to do to call events from a separate thread - no need to create a method stub   - just creating a new **UIThreadHandler** does the job:

EventThrower e = new EventThrower();

UIThreadHandler h = UIManager.CreateHandler(this,new EventHandler(this.UpdateProgressBar));

e.OnEventThrow+=new MyHandler(h.BaseEventHandler);

e.Start();

I think these classes could be expended much further, but for now they save me a bunch of time already. Have fun :)
