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...
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, 但是不保证所有编译器...
Args> void f(const int(&)[N], Args...); int main() { // To call f(int, Args...) when there is just one expression in the initializer list, remove the braces from it. f(3); } 这一新行为会导致重载解决方法要考虑比以往候选更适合的其他候选时,调用将明确地解析为新候选,导致程序...
