Open the long-time source of instant communication

I've seen some recent research on IM that has turned the past upside down to study this research.

Communication protocol UDP, chat peer-to-peer

This project simply realizes the basic function of early QQ.

1. Text chat
2. Emoticons, Pictures sent
3. Send offline messages, pictures
4. Online/offline, file transfer
5. Upload a custom Avatar
6. Group function
7. Voice, video Chat
8. Weather forecast
9. Custom tab
10. Function

Theoretically the function is implemented, but there is a problem with NAT penetration, so peer sometimes can't succeed, so the outside network, just a toy

Client Run

The Technical network communication involved

1. Message serialization, encryption
2. Data transfer Protocol definition, message chunked sending, message integrity judgment and duplicate sending, SOKET5 proxy
3. Nat Pierce, commonly known as punch hole
4. Message Caching/Forwarding

Interface interaction

1. Form interaction
2. Interface Drawing
3. Skin change

RTF Text Processing

1. Font size Color Control
2. RTF Picture Extraction Send

Compiled client, can connect to test server, need to register the account first

ActiveX Control Registration
Voice and video are ActiveX controls that need to be registered before they can be compiled by
The debug directory has a registration file
