wireshark network monitoring

Recently, the company has been developing remote video and remote monitoring projects. We just have time to summarize them, I don't know much about it, just follow the feeling; Query a lot of information, all scattered, some good information on foreign websites, Many of them are implemented using C and C ++. I have limited technical skills and can only use C !! In the early stage of winform testing, it was just a simple step and a simple te

Upload an image first. Implementation Method: ThisProgramWMI is used to dynamically obtain data in WMI. And the calculated results are displayed on the interface. The main WMI classes used are win32_perfrawdata_tcpip_networkinterface and win32_networkadapter. First, use win32_networkadapter to obtain the names of all network adapters in the computer. After selecting different names, you can dynamically obtain the underlying information. The
