Simple remote desktop implementation (viewing only, not controlled)

With the original intention of technical research, you can get a remote desktop.ProgramThere are no technical difficulties in this. Even if there is such a well-developed network, it will be quickly solved.

To achieve Remote Desktop, you must first have a network connection. There is nothing to say. I chose TCP: a client receives data playback, and a server saves screen images and sends them out, this is the idea of the program.

Specific implementation: on the server side, the screen is stored in the memory. After zlib is compressed (the compression ratio is considerable), the packet header contains the size of the compressed data, the size of the screen, and the color depth, the specific compressed data is followed and then sent out. After receiving the data, the client parses the packet header, prepares the memory DC based on the color depth and screen size, and then draws it out.
