保存页面为MHT的代码-优快云博客

介绍了使用Delphi代码将网页保存为单个MHT文件的方法。提到_Stream类在ADODB_TLB单元中，IMessage和IConfiguration接口代码来自cdosys.dll库，还说明了通过Delphi主菜单“Import Type Library”选择“C:\\WINDOWS\\system32\\cdosys.dll”创建CDO_TLB单元。

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;

Sample usage:

  
  WebBrowser1.Navigate();
  
  
  WB_SaveAs_MHT(WebBrowser1,'');

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:\WINDOWS\system32\cdosys.dll" then click the "Create unit" button.
