When we create our streaming provider, should we call StreamingDataProvider.UpdateQuote in the queue of windows messages?

You call .UpdateQuote when a streaming update occurs i.e. when your data feed sent a quote update for a symbol to which you have subscribed.

I have following problem:

1. I open two char windows.
2. Click "Stream" buttons on each windows
3. I close one of windows.

And then in the thread (which processes new quotes) I catch the exception InvalidOperationExceprion: "Invoke or BeginInvoke cannot be called on a control until the window handle has been created."

This is not "our" (Wealth-Lab) problem. It's not generic but is specific to your code.
