保存頁面為MHT的代碼

　　Here's how to save a web page as a single file (mht format) using Delphi code:

uses CDO_TLB, ADODB_TLB;
...
procedure WB_SaveAs_MHT(WB: TWebBrowser; FileName: TFileName);
var
  Msg: IMessage;
  Conf: IConfiguration;
  Stream: _Stream;
  URL : widestring;
begin
  if not Assigned(WB.Document) then Exit;
  URL := WB.LocationURL;

  Msg := CoMessage.Create;
  Conf := CoConfiguration.Create;
  try
    Msg.Configuration := Conf;
    Msg.CreateMHtmlBody(URL, cDOSuppressAll, '', '');
    Stream := Msg.GetStream;
    Stream.SaveToFile(FileName, adSaveCreateOverWrite);
  finally
    Msg := nil;
    Conf := nil;
    Stream := nil;
  end;
end; (* WB_SaveAs_MHT *)

　　Sample usage:

  //first navigate
  WebBrowser1.Navigate('http://Delphi.about.com');
  
  //then save
  WB_SaveAs_MHT(WebBrowser1,'c:WebBrowser1.mht');

　　Note 1: The _Stream class is defined in ADODB_TLB unit that you probably already have created. The IMessage and IConfiguration interfaces code from cDOSys.dll library. CDO stands for Collaboration Data Objects - object librarIEs designed to enable SMTP Messaging.
　　The CDO_TLB is an auto generated unit by Delphi. To create it, from the main menu select "Import Type Library", select "C:Windowssystem32cDOSys.dll" then click the "Create unit" button.
