I am creating an application that I want to print to the windows fax service, automatically using a fax number extracted from a database table. I want to use the windows 2000 fax service if possible. How can I do this in delphi code? I know I can set the printer index to the fax printer, but this will only bring up the fax wizard. I want to use a fax number from the application.

Regards

Gee!

I think the fax service is registered as a DDE service and can be accessed using a DDe client components .

Actually there is an easier way of doing this. If you are using microsoft outlook then you can send a fax simply by sending an email using mapisendmail. You put the fax number in the To: item.

To enable outlook to send faxes all you do is File New Fax and you will be prompted for the outlook cd to add the fax software components.

I can post some mapi mail samples if you want to install the outlook fax software and send using email

Here is some mapi code to send an email too outlook as a fax , the email part was posted on another question recently . I cannot find it anymore but it is someone elses code I have modified, apologies for this.

Remember you must install the fax software in outlook. You can also send the fax to someone in the address book also.

procedure TSMTPForm.Button1Click(Sender: TObject);
var
  R: cardinal;
  mail: TStringList;
begin
  mail:=tstringlist.create;
  try
    mail.values['to']:='FAX@01224878484';
    mail.values['Subject']:='my fax subject';
    mail.values['body']:='my fax body';
    R:=sendEMail(Application.Handle,mail);
  finally
    mail.free;
  end;
end;

function TSMTPForm.SendEMail(Handle :THandle;Mail :TStrings) :Cardinal;
type
  TAttachAccessArray    = array [0..0] of TMapiFileDesc;
  PAttachAccessArray    = ^TAttachAccessArray;
var
  MapiMessage : TMapiMessage;
  R: array [0..2 ] of TMapiRecipDesc;
  Attachments : PAttachAccessArray;
  AttachCount : Integer;
  i1          : integer;
  FileName    : String;
begin
  fillChar(MapiMessage,SizeOf(MapiMessage),#0);
  Attachments := nil;
  fillChar(R[0],SizeOf(R[0]), #0);
  fillChar(R[1],SizeOf(r[0]), #0);
  if Mail.Values['to'] <> '' then begin
    R[0].ulReserved       := 0;
    R[0].ulRecipClass     := MAPI_TO;
    R[0].lpszName         := StrNew(PChar(Mail.Values['to']));
    R[0].lpszAddress      := StrNew(PChar('SMTP:' +Mail.Values['to']));
    R[0].ulEIDSize        := 0;
    MapiMessage.nRecipCount := 1;
    MapiMessage.lpRecips    := @R;
  end;
  if Mail.Values['Cc'] <> '' then begin
    R[1].ulReserved       := 0;
    R[1].ulRecipClass     := MAPI_CC;
    R[1].lpszName         := StrNew(PChar(Mail.Values['Cc']));
    R[1].lpszAddress      := StrNew(PChar('SMTP:' +Mail.Values['Cc']));
    R[1].ulEIDSize        := 0;
    inc(MapiMessage.nRecipCount);
    MapiMessage.lpRecips    := @R;
  end;
  AttachCount := 0;
  for i1 := 0 to MaxInt do begin
    if Mail.Values['attachment'+inttostr(i1)] = '' then
      break;
    inc(AttachCount);
  end;
  if AttachCount > 0 then begin
    GetMem(Attachments, SizeOf(TMapiFileDesc) * AttachCount);
    for i1 := 0 to AttachCount -1 do begin
      FileName := Mail.Values['attachment'+inttostr(i1)];
      Attachments[i1].ulReserved    := 0;
      Attachments[i1].flFlags       := 0;
      Attachments[i1].nPosition     := ULONG($FFFFFFFF);
      Attachments[i1].lpszPathName  := StrNew(PChar(FileName));
      Attachments[i1].lpszFileName  :=StrNew(PChar(ExtractFileName(FileName)));
      Attachments[i1].lpFileType    := nil;
    end;
    MapiMessage.nFileCount := AttachCount;
    MapiMessage.lpFiles    := @Attachments^;
  end;
  if Mail.Values['subject'] <> '' then
    MapiMessage.lpszSubject := StrNew(PChar(Mail.Values['subject']));
  if Mail.Values['body'] <> '' then
    MapiMessage.lpszNoteText :=  StrNew(PChar(Mail.Values['body']));
  Result := MapiSendMail(0,Handle ,MapiMessage,MAPI_DIALOG*Ord(Handle<>0) or
    MAPI_LOGON_UI or MAPI_NEW_SESSION, 0);
  // use this if you don't want the dialog box to come up
  //Result := MapiSendMail(0,Handle ,MapiMessage,0, 0);
  for i1 := 0 to AttachCount-1 do begin
    strDispose(Attachments[i1].lpszPathName);
    strDispose(Attachments[i1].lpszFileName);
  end;
  if assigned(MapiMessage.lpszSubject) then
    strDispose(MapiMessage.lpszSubject);
  if assigned(MapiMessage.lpszNoteText) then
    strDispose(MapiMessage.lpszNoteText);
  if assigned(R[0].lpszAddress) then strDispose(R[0].lpszAddress);
  if assigned(R[0].lpszName) then strDispose(R[0].lpszName);
  if assigned(R[1].lpszAddress) then strDispose(R[1].lpszAddress);
  if assigned(R[1].lpszName) then strDispose(R[1].lpszName);
end;

Hi,

if you don't want to use the API and use the windows 2000 fax service, you have to import the Type Library faxcom 1.0 type library. This option is in your project menu. Install it and then you can use something like this code to send any printable file to the fax. This will open a new window with the application corresponding to the extension and print it. If you want more control, you can explore the other components created after importing the type lib.

var fd: olevariant;
      fs: tfaxserver;
begin
   fs := tfaxserver.Create(application);
   fs.Connect1('');
   fd := fs.CreateDocument('c:\test.txt'); // can be any type of file here as long as you have an application to open it
   fd.FaxNumber := '123';
   fd.Send;
   fs.Disconnect;
end;

hey, where is stated "if you don't want to use the API", should be "... want to use Outlook"

Thanks everybody for the pointers, jduncan for the code. I think Bruno's answer is what I am looking for though, as I did not want to install any other applications such as outlook to send the fax with.

Thanks again for your help
