Why use VB.NET Application Framework

The word frame (framework) has several meanings. In this case, it refers to the foundation on which the application is created and run. Having such a foundation makes it easier to create applications while using a consistent and simplified programming model. As a Visual Basic 6.0developer, you are satisfied with this programming language, which makes it easy to create a variety of applications. The Visual Basic language itself provides inherent data types, such as Integer, Long, and String, as well as some of the most commonly used functions, such as string handling and data type conversion. As your application becomes more complex, you can use Win32 API to perform functions that standard Visual Basic functions cannot do-such as getting arbitrary registration keys and values. In many cases, you can also use the COM (Component Object Model, component object Model) component library to extend the functionality of your application; the most obvious example is the ADO (ActiveX Data Objects) library, which your application can use for data access.

Although Visual Basic is flexible enough to provide these different extensibility mechanisms, this flexibility still requires you to learn several complex API architectures. You need to understand how Win32 works and how to call them in Visual Basic, which can be a time-consuming and error-prone task. You also need to know how to use various COM components in Visual Basic, each with a different object model. * when you use Win32 API, ADO, and possibly many other COM components to create your own Visual Basic applications, you need to manage the deployment of these applications and their dependencies. A typical VB.NET application's dependency list includes much more than the Visual Basic runtime (runtime); it must include all the object libraries used by the application, such as ADO 2.6. The idea behind the common framework is to solve these problems and make it easier for users to create robust applications without having to learn many different API architectures and to deploy and deal with versions of multiple object libraries.

What is. NET Framework

The term .NET Framework refers to the set of technologies that form the basis of the development of the Microsoft .NET platform. The key technologies in this group are runtime and class libraries.

The runtime is responsible for managing the code and providing services to it at execution time, which is similar to the role of the Visual Basic 6. 0 runtime. .net programming languages-including extensions to Visual Basic .NET, Microsoft Visual C #, C++ Management, and a variety of programming languages from different developers-take advantage of various services and features through a common set of unified classes.

The .NET unified class provides the foundation for creating applications, no matter what language you use. Whether you simply concatenate a string or create a Windows service or a multi-tier web-based application, you need to use these unified classes.

Unified classes provide a consistent way to access the functionality of the platform. Once you have learned to use class libraries, you will find that all tasks follow the same consistent architecture. To write your own applications, you don't need to learn and master different API architectures.

Because of the .NET Framework, it is easier to deploy VB.NET application frameworks. Unlike VB.NET applications, you do not need to configure dependencies, such as separate data access libraries, XML parsers, and web API, because all of these features are part of the .NET Framework. By creating your own applications on top of a unified, integrated framework, you can achieve a return on the time it takes to learn such a framework, and you will have more robust applications that are easier to deploy and use.

.net Framework and Visual Basic .NET

The Visual Basic 6. 0 runtime is important in simplifying many common programming tasks. But simplifying this layer means that you can't use new operating system features such as DirectX until you have a package that Visual Basic can use. As a Visual Basic developer, the most important benefit you get from the .NET Framework is that you can access the .NET platform directly and easily using a consistent programming model. This means that you can use Visual Basic .NET to create applications that are difficult or impossible to create using Visual Basic 6.0. As a Visual Basic 6.0developer, you will now appreciate being able to use the same features and functions as other platform languages. To create a Windows service, for example, you no longer have to write it in Microsoft Visual C++, nor do you have to resort to hackers or assembly machines. You can do this elegantly, cleanly, and easily using Visual Basic .NET. To give you some examples of using .NET Framwork, we will discuss four common tasks that you may need to perform in your application: tracing and event logging, multithreading, file system monitoring, and creating Windows services.
