how SendMailMAPI is adjusted to support multiple file attachments
- by Tom
I have this code that sends just one attachment by time, how can I adjust this code to send 1-2 attachments?
function SendMailMAPI(const Subject, Body, FileName, SenderName, SenderEMail,
RecepientName, RecepientEMail: String) : Integer;
var
message: TMapiMessage;
lpSender,
lpRecepient: TMapiRecipDesc;
FileAttach: TMapiFileDesc;
SM: TFNMapiSendMail;
MAPIModule: HModule;
begin
FillChar(message, SizeOf(message), 0);
with message do
begin
if (Subject<>'') then
begin
lpszSubject := PChar(Subject)
end;
if (Body<>'') then
begin
lpszNoteText := PChar(Body)
end;
if (SenderEMail<>'') then
begin
lpSender.ulRecipClass := MAPI_ORIG;
if (SenderName='') then
begin
lpSender.lpszName := PChar(SenderEMail)
end
else
begin
lpSender.lpszName := PChar(SenderName)
end;
lpSender.lpszAddress := PChar('SMTP:'+SenderEMail);
lpSender.ulReserved := 0;
lpSender.ulEIDSize := 0;
lpSender.lpEntryID := nil;
lpOriginator := @lpSender;
end;
if (RecepientEMail<>'') then
begin
lpRecepient.ulRecipClass := MAPI_TO;
if (RecepientName='') then
begin
lpRecepient.lpszName := PChar(RecepientEMail)
end
else
begin
lpRecepient.lpszName := PChar(RecepientName)
end;
lpRecepient.lpszAddress := PChar('SMTP:'+RecepientEMail);
lpRecepient.ulReserved := 0;
lpRecepient.ulEIDSize := 0;
lpRecepient.lpEntryID := nil;
nRecipCount := 1;
lpRecips := @lpRecepient;
end
else
begin
lpRecips := nil
end;
if (FileName='') then
begin
nFileCount := 0;
lpFiles := nil;
end
else
begin
FillChar(FileAttach, SizeOf(FileAttach), 0);
FileAttach.nPosition := Cardinal($FFFFFFFF);
FileAttach.lpszPathName := PChar(FileName);
nFileCount := 1;
lpFiles := @FileAttach;
end;
end;
MAPIModule := LoadLibrary(PChar(MAPIDLL));
if MAPIModule=0 then
begin
Result := -1
end
else
begin
try
@SM := GetProcAddress(MAPIModule, 'MAPISendMail');
if @SM<>nil then
begin
Result := SM(0, Application.Handle, message, MAPI_DIALOG or
MAPI_LOGON_UI, 0);
end
else
begin
Result := 1
end;
finally
FreeLibrary(MAPIModule);
end;
end;
if Result<>0 then
begin
MessageDlg('Error sending mail ('+IntToStr(Result)+').', mtError, [mbOk],
0)
end;
end;
