How to create an application using different national languages

Switching OS Windows into the respective language setting

If an application has to be operated in a foreign language, then the support for this language has to be installed in OS Windows. It goes about the language fonts and also about setting the keyboard layout for the language. The support of individual national languages is set for greater groups in OS Windows, for example:
a) Central Europe with the code page 1250 (Czechia, Slovakia, Poland, Hungary, etc.)
b) Cyrillic with the code page 1251 (Russia)

In OS Windows 2000 and higher it is possible to set the support even for more language groups concurrently. Though it is possible to display texts in various languages in the application concurrently (even from different code pages), based on the installed language groups.

We set the languages itself in Regional Options in Control panel of OS Windows. We set the support for the language groups, the default language, the language for time, currency, etc. format. Further we can set the keyboard layout (even several layouts concurrently and the key sequence for switching between them).

Setting the PROMOTIC system and the application into the respective language

Now we create a new application or open an existing application in the PROMOTIC system and in the development environment of the PROMOTIC system we set the language of the development environment. This language has no impact on the language of the resultant application. The setting is in the Development system language configurator in the "Options > PROMOTIC settings" menu of the application editor.

In the application itself we set the language version of the application. We perform the setting itself in the PmRoot > Application > Main language of runtime configurator. This setting defines the language of system texts in PROMOTIC windows, components, viewers etc. The language setting of the application is accessible by using the Pm.RtLang property.

Next directions

It is possible to create an application that can be switched between more national languages when running. This functionality can be achieved so that in all situations when the national text has to be entered (e.g. the Text configurator of the PmiText graphic item), Macro expression $.text is written instead of the real text. If the macro expression cannot be used (e.g. text is created dynamically in the algorithm), then the Pm.EvalMacro method can be used.
 
The PmWebLang object can be used for creating application, offering HTML pages as Web server and these pages wil be available in multiple language versions. For example the local PROMOTIC application will be running in English, but the Web pages will be offered independently in English/German/Russian ... language version.
 
The example of switching the languages in the runtime mode and offering the Web pages in another languages can be found in the following example: Demo application of PROMOTIC system.

Fully supported languages in the PROMOTIC system

A list of languages with full support and all system texts in the runtime mode PROMOTIC. These texts are contained in the text_sys.xml file that is located in the PROMOTIC installation folder and in the text_rt0.xml file that can be found in the Syst folder. The selection of these languages in running application is done by the All used languages configurator and the main language by the PmRoot > Application > Main language of runtime configurator. In Macro expression $.text, there is a description and syntax of user texts in the application. The example of language switching can be found in Example of language runtime.

Languages without system texts in runtime mode

FOr these languages, the system texts in the runtime mode will be displayed in development mode language or in English. In the configurator All used languages, it is necessary to enter the identifier (id) of the corresponding language(s). In the configurator PmRoot > Application > Main language of runtime, also enter the default runtime language. In Macro expression $.text, there is a description and syntax of user texts in the application. The example of language switching can be found in Example of language runtime.
