Yesterday look at Q3 code, see there is a _intsaizeof macro, really dizzy a burst. Google, finally understand that the role of this macro is to find out the size of variables to occupy memory space, first look at the definition of _intsaizeof

In multi-threaded design mode, if multiple threads are using cout to print information, it is easy to have content alternation, for example:The code is as follows:If you replace cout with printf, then this problem does not occur and results such

Because the program is a 3-tier architecture, all the multi-threaded logging has become a tricky issue, before really did not care about the issue of writing logs, think it is just writing files ~~! Now found that the original to achieve file

#include void Main (){int i=0,j=0,many=100000,many1=100000,num,num1,num2,num4=0,s=0,s1=0;int a=123;int b;printf ("");for (i;i{printf ("*");}printf ("\ n");printf ("");printf ("*");for (i=0;i{printf ("");}printf ("*");printf ("\ n");printf

Several ways to register the OCX control.I. If you are writing a program, you can open vs as an administrator, and then register successfully after compiling.Two. change user Account Control settings, user account and home security, Control Panel,

Factory classes in simple Factory mode typically use static methods to return different object instances by varying the parameters that are received.If you do not modify the code, you cannot extend it.#include using namespace Std;class

1. Why do STL use iteratorsIterator pattern definition: Provides a way to patrol the individual elements contained in a polymer (container) in sequence without exposing the internal representation of the polymer.The main idea of STL is to separate

Factory Method (Factory mode): Defines an interface that is used to create an object, letting subclasses decide which class to instantiate. The Factory method defers the instantiation of a class to its subclasses.Factory mode (Factory)Please mm to

The acid properties of the transaction are as follows: Atomicity): All operations of a transaction are atomic units of work. Modifications to the transaction data are either executed or not executed. Atomicity eliminates the possibility of a subset
