   CreateDevice problem. I'm sure most of people have the same problem
  I have this weirred problem while running the defaul directx sdk samples, for all the samples. They can all be compiled and running successfully. But there always shows a series of same error messages in Immediate Window:"Invalid parameter passed to C runtime function"When I trace it while debugging, it directs to the API DXUT_Dynamic_D3D11CreateDevice, which is under DXUTmisc.cpp.Anyone knows the solution? Although the application still works well, but just annoying to see the error messages during the debugging.
