问题描述：
如何在PB中编写PING代码？
解决方案：
声明外部函数：
Function ulong IcmpCreateFile () Library "icmp.dll"
Function long IcmpSendEcho (ulong IcmpHandle, ulong DestinationAddress, string RequestData,long RequestSize, long RequestOptions, Ref icmp_echo_reply ReplyBuffer, long ReplySize, long Timeout ) Library "icmp.dll" Alias for "IcmpSendEcho"
Function long IcmpCloseHandle (ulong IcmpHandle) Library "icmp.dll"
Function ulong .net_addr (string cp) Library "ws2_32.dll" Alias for "inet_addr"
代码：
ULong lul_address, lul_handle
Long ll_rc, ll_size
String ls_reply
icmp_echo_reply lstr_reply
lul_address = inet_addr(as_ipaddress)
If lul_address > 0 Then
lul_handle = IcmpCreateFile()
ll_size = Len(as_echomsg)
ll_rc = IcmpSendEcho(lul_handle, lul_address, &
as_echomsg, ll_size, 0, &
lstr_reply, 278, 200)
IcmpCloseHandle(lul_handle)
If ll_rc <> 0 Then
If lstr_reply.Status = 0 Then
ls_reply = String(lstr_reply.Data)
If ls_reply = as_echomsg Then
Return True
End If
End If
End If
End If
Return False
//True 表示PING成功，反之失败
