在Delphi中选Project Import Type Library命令,在对话框中选Import Microsoft Shell Controls And Automation类型库,点Install后,在Delphi的ActiveX控件板上就多了TShellFolderItem,TShellLinkObject,TShellFolderView,TShell,TSearchCommand等几个组件
  const
     discVerb = '禁用(&B)';
     connVerb = '启用(&A)';
  function TForm1.DisableEthernet(const EthName,State: String): Boolean;
  var
    cpFolder: Folder;
    nwFolder: Folder;
    nVerbs: FolderItemVerbs;
    i,j,k: integer;
    aItem: TListItem;
  begin
    result := false;
    cpFolder := Form1.shell1.NameSpace(3);
    if cpFolder  nil then
    begin
      for i := 0 to cpFolder.items.Count-1 do
      begin
        if cpFolder.Items.Item(i).Name = '网络和拨号连接' then
        begin
          nwFolder := cpFolder.items.item(i).GetFolder as Folder;
          if nwFolder  nil then
          begin
            for j :=0 to nwFolder.items.Count-1 do
            begin
              if nwFolder.Items.Item(j).Name = EthName then
              begin
                nVerbs := nwFolder.Items.Item(j).Verbs;
                for k := 0 to  nVerbs.Count-1 do
               begin
                  if nVerbs.Item(k).Name = State then
                  begin
                    nVerbs.Item(k).DoIt;
                    aItem := Form1.lvLog.Items.Add;
                    aItem.Caption := FormatDateTime('yyyy-mm-dd hh:mm:ss',now);
                    aItem.SubItems.Add(EthName);
                    aItem.SubItems.Add(State);
                    Result := True;
                  end;
                end;
              end;
            end;
          end;
        end;
      end;
      if nwFolder = nil then
         showmessage('Network and Dial-up Connections not found');
    end
    else
      showmessage('control panel not found');
end;
  
  procedure TForm1.Button1Click(Sender: TObject);
  begin
    DisableEthernet('本地连接',discVerb);
  end;
  procedure TForm1.Button2Click(Sender: TObject);
  begin
    DisableEthernet('本地连接',connVerb);
  end;
