第一句的function int WSAStartup( uint UIVersionRequested, ref s_WSAData lpWSAData ) 其中s_WSAData 是illegal data
我也是同样的问题，我是获取本机IP，别人给的程序差不多完全一样，但是声明过程有错

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
