如何在Delphi程序中获取局域网中相关指定IP地址的计算机的硬盘,CPU,内存的使用情况?[?][?]
 
得到IP地址的方法如下:
function GetIpAddressLIP: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;
begin
try
WSAStartup($101, GInitData);
Result := '';
GetHostName(Buffer, SizeOf(Buffer));
phe :=GetHostByName(buffer);
if phe = nil then Exit;
pptr := PaPInAddr(Phe^.h_addr_list);
I := 0;
while pptr^ <> nil do begin
result:=StrPas(inet_ntoa(pptr^^));
Inc(I);
end;
WSACleanup;
except
on Exception do
Begin
Beep;
end;
end;
end;
 
得到ip地址同一楼,
其它的要用服务端才可能

楼上的CheckNet函数只能通过IP来判断
不知道通过机器名怎么来判断呢
