Reads binary data from the registry.
BOOL GetSectionBinary( LPCTSTR lpszSubSection, LPCTSTR lpszEntry, LPBYTE* ppData, UINT* pBytes );
The lpszSubSection parameter is not an absolute path for a registry entry. It is a relative path that is appended to the end of the default registry key for your application. To get or set the default registry key, use the methods CWinAppEx::GetRegistryBase and CWinAppEx::SetRegistryBase respectively.
