Translating Languages In Delphi - delphi

Question

I have been looking for ages now for some code that can translate any language to another but none of the code I find works.
I know Google has a good translate API but I can't get anyone's Delphi code on it to work.
There is always an error that comes in the way.
Any help would be much appreciated, I need a program that can translate ASAP of my final school project.

Answer 1

The Google Translate API is a good option, but now is available only as a paid service. Instead you can try the Microsoft Translator V2 API, check this article Using the Microsoft Translator V2 API from delphi for more details about how use this API from delphi.
UPDATE
This is the same demo project of the article modified to be compatible with your version of delphi.
program MicrosoftTranslatorApi;
{$APPTYPE CONSOLE}
uses
ShellApi,
ActiveX,
Classes,
ComObj,
Variants,
Windows,
WinInet,
SysUtils;
const
MicrosoftTranslatorTranslateUri = 'http://api.microsofttranslator.com/v2/Http.svc/Translate?appId=%s&text=%s&from=%s&to=%s';
MicrosoftTranslatorDetectUri = 'http://api.microsofttranslator.com/v2/Http.svc/Detect?appId=%s&text=%s';
MicrosoftTranslatorGetLngUri = 'http://api.microsofttranslator.com/v2/Http.svc/GetLanguagesForTranslate?appId=%s';

Answer 2

Maybe you did not find Marco Cantu's works?Works with REST/AJAX/Delphi
But as RRUZ said, the Google Translate API is only available now as a paid service.

Answer 3

First of all, you can not find a 100% tool to translate from a language to another. You can have a tool which is doing some(more or less) of the job for you, but you need to 'polish' the rest. As RRUZ said, you can use the Microsoft's translator but what I've said applies also in this case. Any tool of this type will cost you money. Google's translate is quite good, but you need to pay for it.
PS: I don't think that at school they ask you to create a tool which is translating from any language to any language. Maybe a small tool which can prove you got the concept. just my 2 cents...
