Call CFrameWndEx::DockPane to dock the tabbed window at the main frame. For an example of how to create a tabbed window as a docking control bar, see CTabbedPane Class. To use CMFCTabCtrl as a non-docking control, create a CMFCTabCtrl object and then call CMFCTabCtrl::Create. Inheri...

请注意两个派生类构造函数调用了不同的基类构造函数,区别就是派生类的构造函数写法 Daughter (inta)// nothing specified: call default constructorSon (inta) : Mother (a)// constructor specified: call this specific constructor 多继承 一个类可以继承多个基类,用逗号分隔,例如class Rectangle: public Polygon,...

__call() Calls the named method which is not a class method. CComponent __construct() Constructor. CStack __get() Returns a property value, an event handler list or a behavior based on its name. CComponent __isset() Checks if a property value is null. CComponent __set() Sets valu...
movl%eax,(%esp)call memset leave ret 通过汇编代码可以看出,{0}初始化方式,调用了memset函数! 对三种方法的选取: 1、for 最浪费时间,不建议(其实memset内部也是用循环实现的,只不过memset经过了严格优化,所以性能更高); 2、{0} 可能有移植性问题,虽然绝大多数编译器看到{0} 都是将数组全部初始化为0, 但是...
