C# windows forms not updating in method

Im trying to call some windows forms code (like setting label.visible = true in some event code, everything compiles ok, but form does not react to change! What could be the problem?

Problem is in lines:

labelNewCall.Visible = true;
timerNewCall.Enabled = true;

code : http://pastebin.com/gV28PN4P

also other code did not work, until i reordered some of it (order is not important but it did not work otherwise... )

Use invoke to access object in a windows forms/controls thread

You can also try a handy little method that you can place in your inner-loop:

Application.DoEvents();

Here's the MSDN write up:

This could be because the soundCapture_BufferThrown callback function is not run on the GUI thread. Read this post for more details about threading in WinForms.

Do you call this method in another than UI thread? If so, you should use Invoke and/or BeginInvoke method.

Look at article What's up with BeginInvoke?.
