CWndClassInfo::m_szAutoName
Holds the name of the window class.
TCHAR m_szAutoName[13];
Remarks
CWndClassInfo uses m_szAutoName only if NULL is passed for the WndClassName parameter to DECLARE_WND_CLASS, the DECLARE_WND_CLASS_EX or DECLARE_WND_SUPERCLASS. ATL will construct a name when the window class is registered.
