Create *. Mht-file (Web Archive)

Question

Use the following representation of the function to generate a Web archive from a local html file

function TLessonConstructor2.CreateMHT( const FileName : string):boolean ;
 var
  oMSG:IMessage;
  oConfig: IConfiguration;
  sFileName: string;
  Stream: _Stream;
begin
  //CoInitializeEx(nil, COINIT_APARTMENTTHREADED);
  //CoInitialize(nil);
  try
    Result  := false;
    sFileName := ChangeFileExt(FileName, '.mht');
    DeleteFile(PAnsiChar(sFileName));
    try
    oConfig := CoConfiguration.Create();
    oMSG    := CoMessage.Create();
    oMSG.Configuration := oConfig;
    oMSG.CreateMHTMLBody(FileName,CdoSuppressNone,'','');
    Stream:=oMSG.GetStream;
    Stream.SaveToFile(sFileName,adSaveCreateOverWrite);
    Stream.Cancel;
    Stream.Close;
    Result := True;
    except
      on E: Exception do
      begin
       Result  := false;
       MessageDlg(E.Message, mtError, [mbOK], 0);
      end;
    end;
  finally
  //  CoUnInitialize;
    Stream:=nil;
    oConfig:=nil;
    oMSG:=nil;
  end;
end;

FileName - full path to the html.

After performing oMSG.CreateMHTMLBody (FileName, CdoSuppressNone,'',''); This file is locked for as long as the basic process is completed. However, this file should be removed after processing.

Any idea what the problem is?

CreateMHTMLBody requires URL so for a local file ensure preceded with file:///

CreateMHTMLBody(const URL: WideString; Flags: CdoMHTMLFlags; 
                          const UserName: WideString; const Password: WideString); safecall;
