##Summary

This sample translates the currently selected text in a Word or Excel file into the specified language using the Microsoft Translator service.

This add-in gets the current selection from the Office document and then sends it to the Bing Translator service for a translation into the specified language.

##Prerequisites This sample requires the following:

• Visual Studio 2013 with Update 5 or Visual Studio 2015.
• A subscription to the Microsoft Translator API on Azure Marketplace.
• Word 2013 or later
• Internet Explorer 9 or later, which must be installed but doesn't have to be the default browser. To support Office Add-ins, the Office client that acts as host uses browser components that are part of Internet Explorer 9 or later.
• One of the following as the default browser: Internet Explorer 9, Safari 5.0.6, Firefox 5, Chrome 13, or a later version of one of these browsers.
• Familiarity with JavaScript programming and web services.

##Key components

• CodeSample_TranslateASPNET project
  • CodeSample_TranslateASPNET.xml manifest file
• CodeSample_TranslateASPNETWeb project
  • Home.html. It contains the HTML control for the add-in's user interface.
  • Home.js. It contains the event handler for the Office.initialize event of the add-in, handles the button click event for the add-in's button, calls the ASP.NET web service, parses the response, and updates the UI with the output.
  • Translate.asmx.cs. It defines the web service that handles the HTTP request from the add-in, stores the developer's client ID and client secret, and sends translation requests to the Microsoft Translator service.
  • AdminAccess.cs. It contains the AdmAuthentication and AdmAccess classes that update the access token for the server to communicate with the Microsoft Translator service.

##Description of the code

The sample demonstrates two specific techniques: how to add an ASP.NET web service to an Office Add-in and how to use the Microsoft Translator service. The ASP.NET web service in the solution stores the clientID and clientSecret parameters that the Microsoft Translator service requires to obtain an access token (which, in turn, is required for calling the Microsoft Translator service for a translation).

The Translate.asmx file in the code sample handles HTTP requests coming from the add-in, sends the translation request to the Microsoft Translator service, and then returns the results to the add-in. The AdminAccess.cs file in the App_Code folder handles the access tokens returned from the Microsoft Translator service.

##Build and debug

1. To configure the Translator app, get a client ID and client secret from the Azure DataMarket. For more information, see Obtaining an Access Token.
2. Replace the default values for clientID and clientSecret in the Translate.asmx.cs file with your own values.
3. Open the CodeSample_TranslateASPNET.sln file in Visual Studio.
4. Set the Start Document property of the CodeSample_TranslateASPNETWeb project to either New Excel Workbook or New Word Document.
5. Press F5 to build and deploy the sample add-in Excel or Word.
6. On the Home ribbon, click Open in the Translator group.
7. Type text in a cell of the new Excel workbook or in the new Word document. Select the text.
8. Select your From and To languages, and then press the Translate the selected word button.

Troubleshooting

• If the Translator group does not appear on the Home ribbon, choose Insert > My Add-ins > CodeSample_TranslateASPNET.
• If the app raises a "400: Bad request" exception, ensure that you have replaced the constants in the Translate.asmx.cs file with your own client ID and client secret values. Also, ensure that the HTTP request to the Microsoft Translator service has an Authorization header with a value set to Bearer, a space, and a current access token for the Microsoft Translator service.
