SlimDX form problem

Hello,
I have small problem with SlimDX form problem.
I would like to use SlimDX window renderer - SlimDX::Windows::RenderForm.

Once, object is created and form->Activate(); function is used, but result is .... nothing... windows is not visible.
Message loop is working ok.

Can anyone help me how can I view the correct SlinDX rendering window ?

Many thanks

Jerry
