A reusable multi-language UI switching component on COM

Multi-language UI switching is an import software capability. Most of the previous methods rely on control identifiers, and are performed by the resource files or dynamic link libraries. Since they are closely related to current application, it is different for them to be reused in other systems. Database is a data storage medium independent of any development studios. Store UI texts in database can disassociate the association between texts and identifiers. Software Components are independent of programing languages, can plug and play in applications. Multi-language switching component is implemented by COM technology, it can be easily deployed in other systems; the component stores texts in the database, uses recursive algorithm dynamically converts menus, windows and its various sub-controls´ interface texts. Static UI texts and application-related database data are processed differently according to actual situation. Results show that the multi-language UI switching component has better reusability and reliability.
