Remarks
This window traits class provides a simple method for standardizing the styles used for the creation of an ATL window object. Use a specialization of this class as a template parameter to CWindowImpl or another of ATL's window classes to specify the minimum set of standard and extended styles to be used for instances of that window class.
Use a specialization of this template if you want to ensure that certain styles are set for all instances of the window class while permitting other styles to be set on a per-instance basis in the call to CWindowImpl::Create.
If you want to provide default window styles that will be used only when no other styles are specified in the call to CWindowImpl::Create, use CWinTraits instead.
