You can start an email like this:

shellexecute(Handle, 'open', 'mailto:Fred@fred.com?Hi There!', nil, nil, sw_show);

Though the user then has to fill in the message and send it.

Or you can use something like this which uses mapi to set up a mail message including attachments and send it:

uses mapi;

function SendEMail(Handle :THandle;Mail :TStrings) :Cardinal;
 type
   TAttachAccessArray    = array [0..0] of TMapiFileDesc;
   PAttachAccessArray    = ^TAttachAccessArray;
 var
   MapiMessage : TMapiMessage;
   Receip      : TMapiRecipDesc;
   Attachments : PAttachAccessArray;
   AttachCount : Integer;
   i1          : integer;
   FileName    : String;

 begin
   fillChar(MapiMessage,SizeOf(MapiMessage),#0);
   Attachments:=nil;
   fillChar(Receip,SizeOf(Receip),#0);
   if Mail.Values['to']<>'' then
   begin
     Receip.ulReserved:=0;
     Receip.ulRecipClass:=MAPI_TO;
     Receip.lpszName:=StrNew(PChar(Mail.Values['to']));
     Receip.lpszAddress:=StrNew(PChar('SMTP:' + Mail.Values['to']));
     Receip.ulEIDSize:=0;
     MapiMessage.nRecipCount := 1;
     MapiMessage.lpRecips    := @Receip;
   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);

   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(Receip.lpszAddress)       then
 strDispose(Receip.lpszAddress);
   if assigned(Receip.lpszName)          then
 strDispose(Receip.lpszName);
 end;

procedure TForm1.Button1Click(Sender: TObject);
var
mail : tstringlist
begin
mail:=tstringlist.create;
mail.values['to']:='xyz@zz.com';
mail.values['subject']:='no subject';
mail.values['body']:='no subject';
mail.values['body']:='no subject';
mail.values['attachment0']:='c:\winnt\winnt256.bmp';
mail.values['attachment1']:='c:\winnt\winnt.bmp';
sendEMail(application.handle,mail);
mail.free;
end;

Or you can use something like the SakEmail component and send a mail like this:

procedure TSVOExceptForm.Button1Click(Sender: TObject);

begin
  SakSMTP1.host := 'smtp.trimble.co.nz';
   SakMsg1.CharSet := 'ISO-8859-1';  
   SakMsg1.TextEncoding := te8Bit;
       
SakMsg1.UserName := 'Fred';
   SakMsg1.From := '<Fred@fred.com'+'>';
   SakMsg1.SendTo := 'mary@fred.com';
   SakMsg1.Subject := 'Subject line';
   SakMsg1.Text.Assign(Memo2.Lines);
   SakMsg1.Text.append(' ');
   SakMsg1.Text.AddStrings(Memo1.lines);
   SakSMTP1.connect;
   if not SakSMTP1.SMTPError then
   begin
      SakSMTP1.SendTheMessage( SakMsg1);
      SakSMTP1.quit;
      ShowMessage('Message sent to '+ SakMsg1.SendTo);
   end;
end;

Cheers,

Raymond.

You can also use the TNMSMTP component which ships with delphi, for which I do not have a code sample.

SakEmail can be downloaded from here: http://info.perio.unlp.edu.ar/~sergio/html/sakemail.html

Cheers,

Raymond.
