   Device creation without window ?
  Hi,Is there a way to initialize a device without passing a valid window reference ? What I want to do is just a class used to convert image format via TextureLoader so screen rendering is not used in that case ...--Sinn 
  No, but if you just create the device and never call beginscene/clear/endscene/present nothing will happen, you won''t notice anything. ;  In fact what I m doing was create a surface to render in it ... I was just wondering I could not carry a window in my project .. ;  Well, you don''t have to create a window in the sense of MFC window.  All you really need is a window handle, which is returned by CreateWindow.  You don''t have to display a window or update it or anything.   Chris PergrossiMy Realm | "Good Morning, Dave"
