I wrote a program to send email in delphi xe3 , and it works fine , when I copy the program to another computer (windows 8) it works fine but on Computer (Windows 7) the stmp.send did not respond Unless I install embarcadero on it .I Think the problem is in the files libeay32.dll and ssleay32.dll
Here is the code
var
SMTP: TIdSMTP;
Email: TIdMessage;
SSLHandler: TIdSSLIOHandlerSocketOpenSSL;
begin
SMTP := TIdSMTP.Create(nil);
Email := TIdMessage.Create(nil);
SSLHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
try
SSLHandler.MaxLineAction := maException;
SSLHandler.SSLOptions.Method := sslvTLSv1;
SSLHandler.SSLOptions.Mode := sslmUnassigned;
SSLHandler.SSLOptions.VerifyMode := [];
SSLHandler.SSLOptions.VerifyDepth := 0;
SMTP.IOHandler := SSLHandler;
SMTP.Host := 'smtp.gmail.com';
SMTP.Username := 'Username#gmail.com';
SMTP.UseTLS := utUseExplicitTLS;
SMTP.Port := 587;
SMTP.Password := 'Password';
SMTP.Connect;
Email.Clear;
Email.AttachmentEncoding:='MIME' ;
Email.IsEncoded := true;
Email.Charset := 'utf-8';
Email.ContentType :='multipart/alternative';
Email.Encoding := meMime;
Email.UseNowForDate := true;
Email.From.Address := 'Address' ;
Email.Recipients.EmailAddresses := 'Recipients';
Email.Subject := 'Subject';
Email.Body.Text :='Body' ;
SMTP.Send(Email);
SMTP.Disconnect;
except on E:Exception do
Button1.Caption:=E.Message;
end;
SMTP.Free;
Email.Free;
SSLHandler.Free;
end;
Any idea Thanks
The files libeay32.dll and ssleay32.dll are needed by the executable. Place them in the same folder as the executable and it should work, even when you don't install Delphi on the target computer.

Regards,
Where is this strins resources is stored on the Windows?
I need to show size corectly on native language of installed Windows.
Strings are very specific to the application that is using it. There are no generic string resouce in windows that an application can use. Of course you can write a program to search the resource in the windows folder to see which resource dll has the string that you are looking for and then use that resource dll in your application, but that is unadvisable. The reason being that, any new update of the windows that brings in resource dll changes can break your application.
As the other poster advises, you are better of writing your own resource dll and localize it in the languages that you want to support your application.
This is possible with disk quota library which is available since Windows XP:
function FindStringResourceEx(AInstance: HINST; AStringID: UINT; ALangID: UINT): PWideChar;
var
Res: HRSRC;
LoadedRes: HGLOBAL;
I: Integer;
begin
Result := nil;
Res := FindResourceEx(AInstance, RT_STRING, MAKEINTRESOURCE(AStringID div 16 + 1), ALangID);
if Res <> 0 then begin
LoadedRes := LoadResource(AInstance, Res);
if LoadedRes <> 0 then
try
Result := PChar(LockResource(LoadedRes));
if Assigned(Result) then
try
for I := 0 to (AStringID and 15) - 1 do
Inc(Result, PWord(Result)^ + 1);
finally
UnlockResource(THandle(Result));
end;
finally
FreeResource(LoadedRes);
end;
end;
end;
function GetSizeStrings(out sBytes, sKB, sMB, sGB, sTB, sPB, sEB: string): Boolean;
var
hLib: HMODULE;
sRes: string;
I: Integer;
SL: TStringList;
begin
Result := False;
hLib := LoadLibrary('dskquoui.dll');
if hLib > 0 then
try
SL := TStringList.Create;
try
sRes := FindStringResourceEx(hLib, 14472, MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL));
Result := sRes <> '';
if Result then begin
sRes := sRes.Remove(0, 1);
I := sRes.IndexOf(#$B);
if I > -1 then
sRes := sRes.Remove(I);
SL.Delimiter := #2;
SL.DelimitedText := sRes;
sBytes := SL[0]; // bytes
sKB := SL[1]; // KB
sMB := SL[2]; // MB
sGB := SL[3]; // GB
sTB := SL[4]; // TB
sPB := SL[5]; // PB
sEB := SL[6]; // EB
end;
finally
SL.Free;
end;
finally
FreeLibrary(hLib);
end;
if not Result then begin
sBytes := 'bytes';
sKB := 'KB';
sMB := 'MB';
sGB := 'GB';
sTB := 'TB';
sPB := 'PB';
sEB := 'EB';
end;

My problem is that when I use Indy to send email using Gmail it works ok in this computer where RAD Studio is installed. But when I copy my release version to different computer where is installed Windows 10 it gives an error "SSL negotiation failed"
My code is:
lIOHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
lIOHandler.SSLOptions.Method := sslvTLSv1;
lIOHandler.SSLOptions.Mode := sslmClient;
strA := EditOsoite.Text;
charArray[0] := ';';
o := 0;
IdSMTP1.IOHandler := lIOHandler;
IdSMTP1.UseTLS := utUseRequireTLS;
IdSMTP1.Host := 'smtp.gmail.com'; // EditPalvelin.Text;
//IdSMTP1.Authenticate;
// IdSMTP1.UseTLS := utUseExplicitTLS;
IdSMTP1.Username := EditPalvelin.Text;
IdSMTP1.Password := EditSalasana.Text;
IdSMTP1.Port := 587;
try
try
IdSMTP1.Connect;
IdSMTP1.Send(IdMessage1);
IdMessage1.Clear;
Sleep(1000);
//IdMessage1.Free;
except on E:Exception do begin
ShowMessage('Virhe lähetettäessä');
ShowMessage('There was an error: ' + E.Message);
//StatusMemo.Lines.Insert(0, 'ERROR: ' + E.Message) ;
end;
end;
finally
if IdSMTP1.Connected then begin
IdSMTP1.Disconnect;
//IdSMTP1.Free;

How to programmatically add an application or port to Windows Firewall on Windows XP?
Try this code extracted from our open source SQlite3UI.pas unit:
function GetXPFirewall(var fwMgr, profile: OleVariant): boolean;
begin
Result := (Win32Platform=VER_PLATFORM_WIN32_NT) and
(Win32MajorVersion>5) or ((Win32MajorVersion=5) and (Win32MinorVersion>0));
if result then // need Windows XP at least
try
fwMgr := CreateOleObject('HNetCfg.FwMgr');
profile := fwMgr.LocalPolicy.CurrentProfile;
except
on E: Exception do
result := false;
end;
end;
const
NET_FW_PROFILE_DOMAIN = 0;
NET_FW_PROFILE_STANDARD = 1;
NET_FW_IP_VERSION_ANY = 2;
NET_FW_IP_PROTOCOL_UDP = 17;
NET_FW_IP_PROTOCOL_TCP = 6;
NET_FW_SCOPE_ALL = 0;
NET_FW_SCOPE_LOCAL_SUBNET = 1;
procedure AddApplicationToXPFirewall(const EntryName, ApplicationPathAndExe: string);
var fwMgr, profile, app: OleVariant;
begin
if GetXPFirewall(fwMgr,profile) then
try
if profile.FirewallEnabled then begin
app := CreateOLEObject('HNetCfg.FwAuthorizedApplication');
try
app.ProcessImageFileName := ApplicationPathAndExe;
app.Name := EntryName;
app.Scope := NET_FW_SCOPE_ALL;
app.IpVersion := NET_FW_IP_VERSION_ANY;
app.Enabled :=true;
profile.AuthorizedApplications.Add(app);
finally
app := varNull;
end;
end;
finally
profile := varNull;
fwMgr := varNull;
end;
end;
procedure AddPortToXPFirewall(const EntryName: string; PortNumber: cardinal);
var fwMgr, profile, port: OleVariant;
begin
if GetXPFirewall(fwMgr,profile) then
try
if profile.FirewallEnabled then begin
port := CreateOLEObject('HNetCfg.FWOpenPort');
port.Name := EntryName;
port.Protocol := NET_FW_IP_PROTOCOL_TCP;
port.Port := PortNumber;
port.Scope := NET_FW_SCOPE_ALL;
port.Enabled := true;
profile.GloballyOpenPorts.Add(port);
end;
finally
port := varNull;
profile := varNull;
fwMgr := varNull;
end;
end;
It will allow you to add an application or a port to the XP firewall.
Should work from Delphi 6 up to XE.
