Fat client with VB.net, VB6 and VBA

A fat client, also known as a thick client or rich client, is a software application that performs a significant portion of its processing and functionality on the user's local computer or device, rather than relying heavily on remote servers or the cloud. Unlike thin clients, which depend on server-side processing and minimal local resources, fat clients are characterized by their substantial computational capabilities and storage capacity. This approach often results in a more responsive and feature-rich user experience but may require more resources and maintenance on the client side. Fat clients are commonly used in scenarios where offline functionality, extensive local processing, and user interactivity are essential, such as desktop applications and some mobile apps.

Visual Basic .NET (VB.NET) is a modern, object-oriented programming language developed by Microsoft, known for its ease of use and suitability for developing Windows applications. In contrast, Visual Basic 6 (VB6) is an older, now largely obsolete version of the language, valued for its simplicity and productivity in building Windows software. On the other hand, Visual Basic for Applications &40;VBA) is a scripting language used to automate tasks and extend functionality in Microsoft Office applications, providing a means to create macros and customize Office software for improved productivity and tailored functionality.
