And what happens if you do this:
Form f = new Form();
f.Show();

the problem after the form is shown it flashes for once and it is ok, as you refresh it.

System.Windows.Forms? Tag "Forms".

Not a question. You don't show where you create "uc", you don't show how this fragment of code is called. How do you know that it's called at all?

Well I had problems creating, communicating and opening new forms in c#.
I would recommend you design the form first, then create it on code and modificate its properties for a customize use. For the flashing problem (supposing it flashes and closes) I would depurate it and use form.ShowDialog() preventing it gets disposed before user decides it.
