获取IP地址，在XP中运行正常可以正常读取拨号IP，在WIN7中却无法读拨号IP而读取本地网卡IP，为什么？
//获取IP地址Function GetLocalIp(InternetIP:boolean):String;
type
TaPInAddr = Array[0..10] of PInAddr;
PaPInAddr = ^TaPInAddr;
var
phe: PHostEnt;
pptr: PaPInAddr;
Buffer: Array[0..63] of Char;
I: Integer;
GInitData: TWSAData;
IP: String;
begin
Screen.Cursor := crHourGlass;
try
WSAStartup($101, GInitData);
IP:='0.0.0.0';
GetHostName(Buffer, SizeOf(Buffer));
phe := GetHostByName(buffer);
if phe = nil then
begin
ShowMessage(IP);
Result:=IP;
Exit;
end;
pPtr := PaPInAddr(phe^.h_addr_list);
if InternetIP then
begin
I := 0;
while pPtr^[I] <> nil do
begin
IP := inet_ntoa(pptr^[I]^);
Inc(I);
end;
end
else
IP := inet_ntoa(pptr^[0]^);
WSACleanup;
Result:=IP;//如果上网则为上网ip否则是网卡ip
finally
Screen.Cursor := crDefault;
end;
end;
//Showmessage(GetLocalIp(true));
