You will learn how to work with arrays in this tutorial. With the aid of examples, you will discover how to declare, c initialize array, and access array elements. An array is a type of variable that can store several values. For example, if you wanted to store 100 integers, you could...
如果不兼容,ReadClass将产生一个CArchiveException。例程必须使用DECLARE_SERIAL和IMPLEMENT_SERIAL,否则,ReadClass将产生一个CNotSupportedException。如果pSchema为NULL,则存储类的大纲可通过调用CArchive::GetObjectSchema来恢复,否则,*pSchema将会包含原先存储的运行时类的大纲。可以使用SerializeClass来代替ReadClass,它可以...

return array(); } Returns a list of actions that are used by this widget. The structure of this method's return value is similar to that returned byCController::actions. When a widget uses several actions, you can declare these actions using this method. The widget will then become an ac...
1、‘XXX’declare but never used 变量XXX已定义但从未用过。 2、‘XXX’is assigned a value which is never used 变量XXX已赋值但从未用过。 3、 Code has no effect 程序中含有没有实际作用的代码。 4、Non-portable pointer conversion 不适当的指针转换,可能是在应该使用指针的地方用了一个非0的数值。
