How to use

Server connect to repeater

The approach below use a user(not system) to run the service, when the user's screen has been locked, which will lead to black screen, thus, it's better to use system account to run, in other words run as service.

// 命令行参数如下
// id number: 被控制端编号（只能是数字，唯一，且至少三位，即最小是 100，最大是 2147483647，源码中此为 int 类型）
// ip: repeater 中继器服务器 IP
// port: 中继器 UltraVNC Server 监听端口
winvnc.exe -autoreconnect ID:[id number]-connect [repeater ip]:[server listen port] -run

// Example
winvnc -autoreconnect ID:1001 -connect 101.43.21.21:5500 -run

• How to connect server via service
  Step 1: Open config file ultravnc.ini,
