Working with Classes Tasks

|  Overview |  Details

ClassView, ClassWizard, and WizardBar are tools designed to make it easy to update or add to classes in your project workspace. Such tasks include creating new classes, adding new member functions and variables, mapping messages to member functions, defining Windows message handlers, overriding MFC virtual functions, and adding Automation methods and properties. These tools also let you easily navigate or browse through the class structure.
