# Language Configuration dialog box

How do I open the Language Configuration dialog box?

In FactoryTalk View Studio, from the Tools menu, select Languages.

Use the General tab of the Language Configuration dialog box to:

- Add or remove languages to the list available to the application. You can add up to 40 languages to your application at design time. At run time, up to 20 languages can be available for language switching.
- Export or import language strings
- Change the default language for the application
- Specify whether to show undefined strings as the default language strings or as undefined string "?" characters

The language list shows the languages added to the application, first with the language name and then with the language RFC1766 identification code.

The format for an RFC1766 identifier is: <languagecode2>-<country/regioncode2>

where <languagecode2> is a lower case two-letter code, and <country/regioncode2> is an upper case two-letter code. For example, the RFC1766 code for U.S. English is en-US. The RFC1766 name is not case sensitive.

The languages in the list are supported for language switching. Be sure that these languages are installed on the development and run-time computers before trying to switch languages.

The language in the list that has a check mark beside it is the default language.

The application's current language is shown below the list window. This is the language selected when the application was opened.

Tip: | When you save an application component at design time, the text strings associated with it, such as captions, local messages, and alike, are saved in the application's current language.
