Most Popular & Common Industrial Application Software Scripting

Difference between Visual Basic and old BASIC?

VBA Visual Basic for Applications VBA is a powerful scripting tool that is fully integrated into many industrial SCADA and supporting applications to let you quickly and easily automate operator tasks and create automation solutions. VBA scripts can be as simple or complex as you need them to be, allowing you to add custom functionality and extend your SCADA software as needed to accommodate your automation strategy. Its powerful and easy-to-use development environment allows you to reuse existing Visual Basic code.
VBA is an implementation of Microsoft's event-driven programming language Visual Basic 6, which was declared legacy in 2008, and its associated integrated development environment (IDE). Although pre-.NET Visual Basic is no longer supported or updated by Microsoft, the VBA programming language was upgraded in 2010 with the introduction of Visual Basic for Applications 7 in Microsoft Office applications and it is still popular in industrial applications and customizations.




How it differ from the old BASIC?


  • In BASIC, programming is done in a text-only environment and the program is executed sequentially.
  • In Visual Basic, programming is done in a graphical environment.
  • Users may click on a certain object randomly, so each object has to be programmed independently to be able to response to those actions (events).
  • A VISUAL BASIC Program is made up of many subprograms, each has its own program codes, and each can be executed independently and at the same time each can be linked together in one way or another.
