![]() However, memory is not infinite, and once an application fills the Heap memory space, garbage collection comes into play to free some memory. As long as free memory space is available in the managed Heap, the runtime continues to allocate space for new objects. Each time a new object is created, the common language runtime allocates memory for that object from the managed Heap. Reference types – Reference types store a reference to the value’s memory address and are allocated on the heap.Garbage collection is a low-priority process that serves as an automatic memory manager which manages the allocation and release of memory for the applications. Value types can be built-in, user-defined, or enumerations. Instances of value types are either allocated on the stack or allocated inline in a structure. Value types – value types directly contain their data. It also defines the rules to ensure that objects written in different languages can interact with each other.Ĭommon Type System supports following types: NET platform has a base set of data types provided by CTS.ĬTS ensure that the data types of objects written in various languages are able to interact with each other. It is a formal specification that documents how types are declared, used and managed in order to be used by the CLR.Įvery language running on the. Manages versioning, deployment support, and debugging. Provides various services required in execution of an application such as memory management, garbage collection, thread management, exception handling, security checks etc. NET Framework that converts the source code into an intermediate language called the Microsoft Intermediate Language. In VB.NET, we can create multi threaded applications. We cannot create multithreaded applications in VB6. VB6 uses ADODB for accessing database where as VB.NET uses ADO.NET which is comparatively more efficient and also supports the disconnected data access. It means handling versioning and deploying applications is easier in VB.NET than in VB6 VB6 uses COM (Component Object Model) as component architecture where as VB.NET uses assemblies as its component architecture. Moreover the compiled code is cached to increase efficiency VB6 interprets the code whereas VB.NET compiles the code. NET’s Common Language Runtime Which allows it to run on different platforms and operating systems VB6 uses the VB-Runtime for running programs whereas VB.NET uses the. ![]() VB6 uses ASP to build web applications where as VB.NET uses ASP.NET to build web Applications. NET Runtime and Framework that adds several features like faster program execution and better memory management etc. VB.NET is an enhancement to VB6 and used for developing web applications, distributed applications, web services etc. VB6 is a powerful and simple language used to create desktop Window applications or reusable ActiveX libraries. What is difference between VB and VB.NET?įollowing are the differences between VB and VB.NET: Microsoft AJAX Library – It is used to create highly responsive web applications with minimum efforts. so, it can be used in applications to connect to these data sources and retrieve, manipulate, and update data. Supports ADO.NET- It provides access to data sources such as Microsoft SQL server, XML etc. The library is organized as namespaces and can be easily used in any application by just including the namespaces at the top. NET allows exchanging of data type between programs developed in different languages.īase Class Library: It contains classes, value types, and interfaces required in application development. Language Independence: Through Common language infrastructure specifications (CLI). ![]() NET code including memory management, debugging and exception handling. a large library and supports several programming languages hence enable us to use codes written in different languages.Ĭommon Runtime Engine: It provides a runtime environment for the execution of code written in. It is a collection of tools, technologies, and languages that provides an environment to build and deploy robust enterprise applications easily. NET framework is a software development framework from Microsoft.
