Não Repita Código! Otimize seu Sistema VBA (Aula 3)

Lesson 3 – Optimization and Security in the Input/Output System | Excel VBA Welcome to the third lesson in the Input/Output System in Excel VBA series, developed by Helix Academy! In this lesson, we will transform our system into a much smarter, safer, and more professional project. You will learn how to reuse the same programming routine to register new products and edit existing products, avoiding code duplication and making system maintenance much simpler. In addition, we will implement one of the most important features in any management system: the validation of duplicate codes, preventing the database from receiving repeated information. We will also see how to automatically locate records using the Find method, load data directly from the spreadsheet to the form, and better organize the project using Public Variables. In this lesson you will learn: ✅ Code reuse for Registration and Modification. ✅ How to create Public Variables. ✅ Automatic search using the Find method. ✅ How to prevent duplicate product codes. ✅ Using On Error GoTo for error handling. ✅ Automatic loading of codes into a ComboBox. ✅ Professional organization of the VBA project.
