Threading question

[Vadym Stetsyak]

Hello!

I've got a class, representing Windows Form (Form1);
When I launch new thread user interface e.g. Form1 stops responding until
the worker thread is completed.

So the question - how this can be avoided. Roughly speaking I need to
perform some job after the button click and while this job is completing
user GUI can respond.

Here is the code I'm using:
ThreadStart threadStart = new ThreadStart(DoSomething);

Thread thread = new Thread (threadStart);
thread.Start();

In the debuger thread.Start() returns immediately. But GUI freezes until the
work thread is completed.

Does "DoSomething" try to access UI components? That is *not* allowed.

Actually yes. I am quite a newbie to Windows Forms and C#.
Thanks for the answer.
