1.Run AppWizard(.exe),check SDI.Choose CFormView base class instead of CView.
2.Insert->Resource->Dialog->IDD_Dialog1.
3.Project->Add to project->New->Student.h and Student.cpp.
4.Define a student class that inherits the base class Cobject to make the class serializable and override the function serialize().
5.Modify the Document and View class.
6.Build and test the application.
