I am using win32 to make my bassic window for my OpenGl app. I want to be able to switch from windowed to full screen modes and vise versa. Here are the steps I do. I Init my app by telling it to be either Full or Windowed, then for full screen I use createwindowex with ws_popup and for windowed I use ws_overlapped. This is ok. What I want to do is lets say I am in windowed and I press a key to switch to fullscreen I want the window to change from overlapped to popup so bassicly loose the title bar etc... and when I switch bak to restore the style. I know there is ModifyStyle function for MFC is there anything similar for win32?

Both ModifyStyle and ModifyStyleEx are Win32API functions as well as MFC functions. Take a look at the CWindow:: form of both in your help files for function parameter information.
