Delphi开发的IP地址修改工具

用Delphi进行开发的，直接修改注册表，需重启电脑后才生效

procedure TForm1.SpeedButton3Click(Sender: TObject);
var
  reg:TRegistry;
  IP,WG,ZY:array [0..255] of char;
  ID,CardNum:string;
  Psize:Dword;
  DNS:string;
begin
  reg:=TRegistry.Create;
  name:='';
  reg.RootKey:=HKEY_LOCAL_MACHINE;
  ID:=RGcardList.Items.Strings[RGCardList.itemindex];
  cardNum:=copy(ID,pos(';',ID)+1,length(ID));
  reg.CloseKey;
  if length(CardNum) < 2 then
    CardNum:='00'+CardNum;
  if LengTh(CardNum) < 3 then
    CardNum:='0'+CardNum;
  reg.OpenKey('SYSTEM\ControlSet'+CardNum+'\Services',false);
  reg.OpenKey('Tcpip\Parameters\Interfaces',false);
  ID:=CardIdLt.Strings[CardIDLt.IndexOf(ID)+1];
  reg.OpenKey(id,false);
  DNS:=Reg.ReadString('NameServer');
  RegqueryValueEx(reg.CurrentKey,'IPAddress',nil,nil,@IP,@Psize);
  Edit1.Text:=copy(IP,0,strlen(IP));
  RegqueryValueEx(reg.CurrentKey,'SubnetMask',nil,nil,@ZY,@Psize);
  Edit2.Text:=copy(ZY,0,strlen(ZY));
  RegqueryValueEx(reg.CurrentKey,'DefaultGateway',nil,nil,@WG,@Psize);
  Edit3.Text:=copy(WG,0,strlen(WG));
  RegqueryValueEx(reg.CurrentKey,'SubnetMask',nil,nil,@ZY,@Psize);
  Edit2.Text:=copy(ZY,0,strlen(ZY));
  RegqueryValueEx(reg.CurrentKey,'IPAddress',nil,nil,@ZY,@Psize);
  Edit1.Text:=copy(ZY,0,strlen(ZY));
  Reg.CloseKey;
  reg.Free;
  if pos(',',DNS)<=0 then begin Edit4.Text:=DNS;  end;
  if pos(',',DNS)>0 then
    begin
      Edit4.Text:=Copy(DNS,0,Pos(',',DNS)-1);
      Edit5.Text:=Copy(DNS,Pos(',',DNS)+1,Length(DNS));
    end;
end;
