获得机器IP地址

声明win32 API函数：

function int WSAStartup( uint UIVersionRequested, ref s_WSAData lpWSAData ) library "wsock32.dll"

function int WSACleanup() library "wsock32.dll"

function int WSAGetLastError ( ) library "wsock32.dll"

function int gethostname ( ref string name, int namelen ) library "wsock32.dll"

function string GetHost(string lpszhost, ref blob lpszaddress ) library "pbws32.dll"

使用方法：

s_wsadata l_WSAData

string ls_HostName = space(128)

string ls_IpAddress

int li_version = 257

blob{4} lb_hostaddress

IF wsastartup ( li_version, l_WSAData ) = 0 THEN

IF gethostname ( ls_HostName, len(ls_HostName) ) < 0 THEN

messagebox("GetHostName",WSAGetLastError())

ELSE

GetHost(ls_HostName, lb_HostAddress)

ls_IpAddress = string(asc(string(blobmid(lb_HostAddress,1,1))),"000") + "."

ls_IpAddress += string(asc(string(blobmid(lb_HostAddress,2,1))),"000") + "."

ls_IpAddress += string(asc(string(blobmid(lb_HostAddress,3,1))),"000") + "."

ls_IpAddress += string(asc(string(blobmid(lb_HostAddress,4,1))),"000")

END IF

WSACleanup()

ELSE

messagebox("GetHostName",WSAGetLastError())

END IF

sle_1.text=ls_hostname

sle_2.text=ls_ipaddress
