Deleting a Member Function

  • Article

|  Overview |  How Do I | 

You can delete a member function by using ClassWizard, ClassView, or WizardBar. Deleting a function with ClassView or WizardBar removes the function declaration from the header (.h) file, removes any associated map entry from the MSG, MESSAGE or DISPATCH map, and comments out the function definition, if one exists. The function body remains selected so that you can easily delete it permanently if you wish.

If you delete a member function in the ClassWizard dialog box, the declaration is deleted from the class in the header file, and (if it is a message handler) any message-map entry is deleted from the implementation file. However, you must also manually remove the function definition, as well as any references to the function, from the implementation file. Browse through the class structure with ClassWizard to help you locate these references.
