In all but the most trivial dialog box, you add member variables to your derived dialog class to store data entered in the dialog box's controls by the user or to display data for the user. You can use the Add Variable wizard to create member variables and associate them with controls....
The declaration specifier before thestructkeyword applies to variablenode. The class key modifier after thestructkeyword applies to the typeBinaryTree. Rules for Using These Specifiers A symbol definition may be redeclared with a more restrictive specifier, but may not be redeclared with a less restr...
