Как послать e-mail, чтобы пользователь даже не знал об этом(с вложенным файлом)!

Когда я компилирую данный код он выдаёт ошибки.
Вот код модуля программы:

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs;

type
TForm1 = class(TForm)
function SendEmail(const RecipName, RecipAddress, Subject, Attachment: string): Boolean;

function IsOnline: Boolean;

private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.dfm}
function SendEmail(const RecipName, RecipAddress, Subject, Attachment: string): Boolean;
var
MapiMessage: TMapiMessage;
MapiFileDesc: TMapiFileDesc;
MapiRecipDesc: TMapiRecipDesc;
i: integer;
s: string;
begin
with MapiRecipDesc do begin
ulRecerved:= 0;
ulRecipClass:= MAPI_TO;
lpszName:= PChar(RecipName);
lpszAddress:= PChar(RecipAddress);
ulEIDSize:= 0;
lpEntryID:= nil;
end;

with MapiFileDesc do begin
ulReserved:= 0;
flFlags:= 0;
nPosition:= 0;
lpszPathName:= PChar(Attachment);
lpszFileName:= nil;
lpFileType:= nil;
end;

with MapiMessage do begin
ulReserved := 0;
lpszSubject := nil;
lpszNoteText := PChar(Subject);
lpszMessageType := nil;
lpszDateReceived := nil;
lpszConversationID := nil;
flFlags := 0;
lpOriginator := nil;
nRecipCount := 1;
lpRecips := @MapiRecipDesc;
if length(Attachment) > 0 then begin
nFileCount:= 1;
lpFiles := @MapiFileDesc;
end else begin
nFileCount:= 0;
lpFiles:= nil;
end;
end;

Result:= MapiSendMail(0, 0, MapiMessage, MAPI_DIALOG
or MAPI_LOGON_UI or MAPI_NEW_SESSION, 0) = SUCCESS_SUCCESS;
end;

function IsOnline: Boolean;
var
RASConn: TRASConn;
dwSize,dwCount: DWORD;
begin
RASConns.dwSize:= SizeOf(TRASConn);
dwSize:= SizeOf(RASConns);
Res:=RASEnumConnectionsA(@RASConns, @dwSize, @dwCount);
Result:= (Res = 0) and (dwCount > 0);
end;

end.
