If you are not familiar with network programming, we recommend that you first learn the network programming section of Linux + signal model (or Windows Network Programming + complete port model ). Ace is a good package. It encapsulates these models, but there is no good theoretical basis. It is unlikely to design a high-performance network server.
For more information about network server models, see c10k. Of course, in Linux, the best model would be epoll ?). Currently, a server supports access
Client and server program templates supported by network programming:
1. connect multiple clients to the server at the same time, that is, the service program can serve multiple clients at the same time;
2. The server supports socket pair reuse, that is, even in the time_wait status, the server can be restarted;
3. The server can check whether the client is disconnected;
4. The standard input of the client
3. Updater Application Block: This module is mainly responsible for automatic updating of programs. In the fat client mode, it is very troublesome to deploy and update programs. Especially when there are hundreds of clients, we have to process them one by one, in this way, we will waste a lot of time and energy, and it is very easy to make mistakes. The Updater Application Block provides a good solution. Each time the client starts, the program checks

After reading the system demo you developed earlier, I thought that you are fully capable of developing our system. I am not planning to talk to anyone else, because I am not allowed to do this during my time. If you think that the demand content and Development price are both appropriate, then we will start to cooperate.

mentioned above, the development of cab-Based Smart Clients is case-centric. Therefore, it is critical to understand the client-based business. First, there are three aspects that affect the development process: shell, infrastructure services, and specific use cases. Therefore, to design a complex Smart Client, follow the following three principles:
1. First, you must have a deep understanding of the general requirements for most use cases. General f
Program requirements:
Programs are divided into server programs and client programs. The client initiates a request for a specified file and transmits the file to the client.
One server supports communication between multiple clients.
Data packets must have a verification mechanism.
There is a packet loss retransmission mechanism.
Supports resumable data transfer.
Can handle various exceptions normally.

As we all know, iOS9 has begun to force the use of Https to replace the original Http request in terms of networking. Although Http and Https have their own advantages, in general, it is now in this secure information age, developers can no longer leave Https.
There are a lot of Https tutorials on the Internet, but they
