myinteger i;// is equivalent to int i;mystring s;// is the same as char *s;myfunc f;// compile equally as void (*f)(); 回调函数(Callback Function) 如果说 函数指针 是语言相关的话**,回调函数 就是一个语言无关的概念了。回调函数这个名字起的很好,可以明显感受到它有点 “返过来调用的...
事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来讲述...

When the callback is specified as a string, it will be first assumed to be a method of the current controller class. If the method does not exist, it is assumed to be a global PHP function. Note, the callback should return the dynamic content instead of echoing it....

The constructor is protected because you must derive your own dialog-box class to implement a modeless dialog box. Construction of a modeless dialog box is a two-step process. First call the constructor; then call the Create member function to create a resource-based dialog box, or call ...
The framework calls this function to determine whether the pane supports auto-hide mode.During construction, you can set this ability by passing the AFX_CBRS_AUTOHIDE flag to CBasePane::CreateEx.The default implementation checks for the AFX_CBRS_AUTOHIDE flag. Override this method in a derived...
