windows form looping?

I want to add some while() loop to a windows form app, the problem is that when I try its freezing the window because of the loop.

There is any way or method to add a loop that won't freeze the window?

The best method (though I don't have any advice on it) is using a background worker: http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.aspx

Maybe you should add a thread.

Yep, background worker did the job!
I found a nice tutorial, for some reason you need to replace the "." with "->" but it really great tutorial:

(after all it isn't possible to learn C++ from MSDN which isn't understandable in most of the cases)
