Domeniul - abonati telefonici Observatii - TipAbonament, Clienti, Plati, ExtraOptiuni Cerintele 1. Declare / implement the entities (classes) 2. Create forms that allow users to input / update / delete data 3. Add data validation (ErrorProvider control, Validating/Validated events, standard exceptions, custom exceptions) 4. Implement Alt Shortcuts 5. Add data serialization / deserialization 6. Add the option to export a report as a txt file 7. Use the following menu controls: MenuStrip, ToolStrip, StatusStrip, ContextMenuStrip 8. Draw a chart using the [login to view URL] class, in order to represent some statistics that are meaningful for your application. You should not use an existing chart control, like the one available in the ToolBox (the goal is to create such a control yourself). The control should be different from the ones available on [login to view URL] (discussed during the course / during the labs). You can check the charts in Microsoft Excel for inspiration. 9. Offer the possibility to print a document (with PrintPreview) 10. Implement the drag & drop functionality 11. Use a relational database in order to persist data (for at least two different entities / classes) in your app 12. Implement a UserControl (so that it can be distributed to other developers) in a separate project and use it in your app. The UserControl should provide a useful functionality for your app (please don't copy&paste a clock usercontrol from the internet ;) ) Rules: - only upload *.zip archives (no *.rar, *.bin, etc); - don't include the "bin" and "obj" folders
