First, the basic knowledge of verification code
1. The main purpose of the verification code is to force human-computer interaction to withstand machine automation attacks.
2. Most of the verification code designers do not have the essentials, do not understand image processing, machine vision, pattern recognition, the basic concept of artificial intelligence.
Chapter 4 CopyOnWriteArraySet source code parsing: copyonwritearrayset
Note: Before reading this article, if you are not clear about the bottom layer of CopyOnWriteArrayList, we recommend that you first check the source code parsing of CopyOnWriteArrayList.

In this article, we will not use ajax to upload a non-refreshing file, but use iframe to simulate ajax to implement a non-refreshing File Upload. If you need it, you can refer to the example below.
Let's take a look.
Let's download the full instance source code of the plug-in.

There's no point in using printf in a compilation, it's just a matter of writing, and the use of printf in __asm is a bit complicated. Let's look at the following code:
void Main (){int t = 10;char *szformat = "T =%d/n";printf (Szformat, T);}
===Output
t = 10Press any key to continue
Debug the resulting assembly code:

message ends.
The message header + message body is a fixed-length message. The first few bytes are the message header followed by the message header.What is used in Mina is
The message length + the first four bytes are used to store the message length and determine when the current message ends.

In the network, information is transmitted in bytes. When we write our own code, it is a specific object, if we want our objects to
