VS2010中的BackgroundWorker不在其他线程中运行

Question

I created a WinForm in Visual Studio 2010 (c++), almost the same as this example: http://msdn.microsoft.com/en-us/library/waw3xexc.aspx

but when I click on the button that "lunch" the BackgroundWorker it "stucks" the WinForm, so I can't move it or click on "stop button" for the time the function runs.

The function runs as desired - is returns the expected result, and also the progress bar is ok. It seems that the BackgroundWorker runs in the same thread as the WinForm.

What might be the problem?

Thanks!

Answer 1

I found the problem.

The BackgroundWorker actually runs on another thread but it send Events of update progress too often and those events "lunch" function in the main form - that updates ProgressBar - and this funcion "stucks" the form.
