Visual DataFlex is a powerful programming language that is specifically designed for building business applications. It has been in use for over three decades and has a loyal following of developers who appreciate its power and flexibility. In this beginner's guide, we will take a look at the history of Visual DataFlex, how to write code using the language, and some of the best applications for it.
History of Visual DataFlex:
Visual DataFlex was first released in 1992 by Data Access Worldwide, a company based in Miami, Florida. It was originally created as a successor to the DataFlex language, which had been in use since the early 1980s. Visual DataFlex was designed to be a modern, object-oriented language that could run on Windows-based platforms. Since its release, Visual DataFlex has gone through several iterations and upgrades, and it remains a popular language for building business applications.
How to Write Code in Visual DataFlex:
Visual DataFlex is a language that is relatively easy to learn, even for beginners. One of the key features of the language is its use of visual components, which can be used to build user interfaces quickly and easily. To get started with Visual DataFlex, you will need to install the development environment, which includes the Visual DataFlex Studio, the language's integrated development environment (IDE). Once you have installed the IDE, you can start creating new projects and writing code.
Here is an example of a simple Visual DataFlex program that displays a message box:
```
Program MessageDemo
Begin
Message("Hello, World!")
End_Program
```
In this program, we define a new program called MessageDemo. The `Begin` keyword indicates the beginning of the program code, and the `End_Program` keyword indicates the end of the program. Inside the `Begin` and `End_Program` keywords, we call the `Message()` function, which displays a message box with the text "Hello, World!".
Best Applications for Visual DataFlex:
Visual DataFlex is an ideal language for building business applications, particularly those that require a high level of customization or integration with other systems. Some of the best applications for Visual DataFlex include:
- Enterprise Resource Planning (ERP) systems
- Customer Relationship Management (CRM) systems
- Order entry and fulfillment systems
- Inventory management systems
- Accounting and finance systems
Conclusion:
Visual DataFlex is a powerful and versatile programming language that is well-suited to building business applications. Whether you are a beginner or an experienced developer, Visual DataFlex offers a wide range of tools and features that can help you create powerful and customized applications. With its intuitive visual components and powerful object-oriented architecture, Visual DataFlex is a language that is worth exploring for anyone who is looking to build business applications.
