VB源码：海康登录窗口，视频监控相关实例，实现了查询各路图像，测试编译前请将最新的网络sdk放在程序目录下面，否则程序可能达不到预期功能，测试界面截图如下图示。源代码内涉及了IPC获取CCD参数配置、获取抓拍机IO输入参数、设置IO闪光灯输出参数、获取单IO触发抓拍功能配置、输入的IO口状态，0-下降沿，1-上升沿，2-上升沿和下降沿，3-高电平，4-低电平、红绿灯功能（2个IO输入一组）、测速功能、白平衡配置等相关编写要点。

-VB source: Haikang login window, video surveillance related examples, the realization of the query each image, test before compiling the new network SDK under the program directory, otherwise the program may not reach the expected function, test interface screenshots as shown below. The source code to IPC for CCD parameter configuration, access to capture IO input parameters, set the IO flash output parameters, to obtain single IO triggered snapping function configuration, the input port IO, 0- falling edge, the rising edge of 1-, the rising edge of 2- and falling edge of 3-, high level, low level, 4- traffic lights function (2 IO inputs a group), speed, white balance allocation and other related writing points
