VC实现的类似Windows Netstat命令查看开放端口的源码，并不是一个完整的程序。NPort.cpp : 显示端口及对应的文件名,相当于Netstat -noa命令. 适用于XP及较高级版本.所用的iphlpapi.dll中的函数原型定义，生成IP地址字符串。以下为与TCP相关的结构：

　　typedef struct tagMIB_TCPEXROW{

　　DWORD dwState // 连接状态.

　　DWORD dwLocalAddr // 本地计算机地址.

　　DWORD dwLocalPort // 本地计算机端口.

　　DWORD dwRemoteAddr // 远程计算机地址.

　　DWORD dwRemotePort // 远程计算机端口.

　　DWORD dwProcessId

　　} MIB_TCPEXROW, *PMIB_TCPEXROW -VC to achieve a similar Windows Netstat command to check open ports of the source, not a complete program. NPort.cpp: display port and the corresponding file name, which is equivalent Netstat-noa command for XP and higher versions of the definition of the function prototype iphlpapi.dll used in generating IP address string.. The following is the structure associated with the TCP:

typedef struct tagMIB_TCPEXROW {

DWORD dwState // connection status.

DWORD dwLocalAddr // local computer address.

DWORD dwLocalPort // local computer port.

DWORD dwRemoteAddr // remote computer address.

DWORD dwRemotePort // remote computer port.

DWORD dwProcessId　

} MIB_TCPEXROW,* PMIB_TCPEXROW
