在Delphi中選Project Import Type Library命令，在對話框中選Import Microsoft Shell Controls And Automation類型庫，點Install后，在Delphi的ActiveX控件板上就多了TShellFolderItem，TShellLinkObject，TShellFolderView，TShell，TSearchCommand等幾個組件

const
   discVerb = '禁用(&B)';
   connVerb = '啟用(&A)';

function TForm1.DisableEthernet(const EthName,State: String): Boolean;
