If you develop a Microsoft Foundation Classes (MFC) application by using Microsoft Visual Studio .NET 2003, and the application contains OLE components, all the components may not register successfully if one of the components has a NULL PROGID parameter. This problem may cause unexpected behavior when you run the application because component information may not appear in the registry.
When the IMPLEMENT_OLECREATE macro registers the components in an MFC application, if the value that is passed for the external_name parameter is NULL, the next call to the UpdateRegistry function returns FALSE and the UpdateRegistry function does not update the component information in the registry. This behavior causes MFC to abort the registration process. Therefore, information about the other components in the application is not updated in the registry.
