ENROLL: A Sample MFC Database Application

  • Article

ENROLL is an example of a Microsoft Foundation Class Library (MFC) database application. The ENROLL sample has four subdirectories, named STEP1, STEP2, STEP3 and STEP4. The first three subdirectories correspond to steps in the . STEP4, which adds more advanced features to the ENROLL database application, is not discussed in the tutorial but is discussed below.

The first three steps of ENROLL illustrate the following.

  • Code created by the AppWizard database option.

  • CRecordset and CRecordView classes.

  • Using MFC database classes in conjunction with the framework's document/view architecture.

  • Adding, updating, and deleting database records.

  • Handling database exceptions.

STEP4 of ENROLL illustrates the following.

  • Using multiple CRecordView-derived classes.

  • Switching views in a frame window.

  • Using update hints and CDocument::UpdateAllViews to coordinate multiple record views.

ENROLL STEP4 has the same user interface as ENROLL STEP3, with the addition of a new Form menu and a Course form. The Form menu lets you toggle between the Sections form and the Course form. When you add or delete a course in the Course form, the change is automatically reflected in the list of courses displayed in the dialog box in the Section form.

****Note   ****To run the ENROLL application, you must first set up the Student Registration Database and register it with ODBC. For information about how to do this, see .
