Development of a Vietnamese-English user interface for the Mathematical Modeling and Simulation software

Abstract

Using the source code of the Vietnamese version and the Delphi integrated development environment, this study implemented a Vietnamese - English user interface switching feature for the Mathematical Modeling and Simulation (MM&S) software. The implementation of the Vietnamese - English language switching feature began with the identification and declaration of variables representing notifications, terms, text strings, and prompts used throughout the software. Subsequently, Vietnamese or English text values corresponding to the user-selected language were assigned to the menus and to the variables previously declared within each module. Language switching procedures for all modules are performed when the user selects a language option. When the language is switched, only the user interface is translated, while the names of system elements and variables remain unchanged in both the simulation diagram and in the model output tables. As a result, users require only a single version of MM&S, and future feature development can be carried out using a single codebase.
