   resize window
  hi:i found if i resize rendering window, the demo will be crashed at effect->end().when i resize the window,i used OnResetDevice to reset my effect. but, there is unusefull. so, why?thanks a lot!   
  D3D9? D3D8? D3D10?Have you resized buffers? (if not d3d10)   ;  Define "Crash". What is the exact error you get? What line does the error occur on in your code (The debugger will tell you)? Do the pointers look correct (Not null, vtable not 0xfeeefeee, etc)? Anything from the Debug Runtimes?
