Full screen windows form but with title bar

I am following this article, http://www.vesic.org/english/blog-eng/net/full-screen-maximize/

This makes my windows form to go full screen but it also hides Title bar.

I want to hide task bar but like to have my title bar.

" targetForm.FormBorderStyle = FormBorderStyle.None;" hides my title bar but removing this shows task bar so is there anyway to hide task bar and keep title bar in windows app? Thanks

public static int ScreenX
{

}

public static int ScreenY

SetWindowPos(hwnd, HWND_TOP, 0, 0, ScreenX, ScreenY, SWP_SHOWWINDOW);
}

Answer

You can set it to FormBorderStyle.FixedToolWindow;, than only the taskbar is hidden.
