Visual Basic is a 3rd generation occasion driven programming language first introduced and delivered by Microsoft in 1991. It developed from the previous DOS form called BASIC which is a first-generation computer language formed as Beginners’ All-purpose Symbolic Instruction Code. From that point forward Microsoft has delivered numerous forms of Visual Basic, from Visual Basic 1.0 to the latest version Visual Basic 6.0. Visual Basic is an easy-to-use programming language intended for beginners, and it empowers to create GUI window applications without any problem.
In 2002, Microsoft delivered Visual Basic.NET (VB.NET) to supplant Visual Basic 6. From there on, Microsoft pronounced VB6 a heritage programming language in 2008. Fortunately, Microsoft actually gives some type of help to VB6. VB.NET is a completely object- oriented programming language executed in the .NET Framework. It was made to provide catering the needs for the improvement of the web just as portable mobile applications. However, numerous designers actually favour Visual Basic 6.0 over its replacement Visual Basic.NET.
The Visual Basic 6 Integrated Development Environment
Before writing programs in VB 6, it needs to introduce Visual Basic 6 compiler on PC. One can buy a duplicate of Microsoft Visual Basic 6.0 Learning Edition or Microsoft Visual Basic Professional Edition or Microsoft Visual Basic 6.0 6 Professional PRO MSDN Library Manual Service Pack. If it is already pre-installed Microsoft Office utilize the implicit Visual Basic Application in Excel to begin making Visual Basic projects without going through additional money to purchase the VB6 compiler.
The Form is the essential structure square of a Visual Basic 6 application. A Visual Basic 6 application can actually include numerous structures, yet we will focus in on building up an application with one structure first. We will figure out how to create applications with numerous structures later. Before you continue to assemble the application, it is a decent practice to save the task first. You can save the venture by choosing Save Project from the File menu, appoint a name to your task and save it in a specific organizer. You will presently continue to take in Visual Basic programming from the following exercise onwards.
Managing Visual Basic Data
We go over a wide range of information in our everyday life. For instance, we need to deal with information like names, addresses, cash, date, stock statements, insights and all the more consistently. Also, in Visual Basic, we need to manage a wide range of information, some can be numerically determined while some are in the structure text or different structures. Visual Basic isolates information into various kinds so they are simpler to oversee when we need to compose the code including that information.
- Numeric Data Types
- Non-numeric Data Types
- Suffixes for Literals
Managing Variables in Visual Basic
Variables resemble letter boxes in the mail centre. The substance of the variables changes occasionally, actually like the letter boxes. In term of VB, factors are zones allotted by the PC memory to hold information. Like the letter boxes, every factor should be given a name. To name a variable in Visual Basic, you need to observe a bunch of rules.
- Variable Names
- Declaring Variables Explicitly
- Scope of Declaration
Overview of Visual Basic
Visual Basic programming language is an Integrated Development Environment, which was first evolved by Microsoft. This language is created from BASIC that will empower the web designers to construct site pages utilizing pre-characterized devices other than giving Rapid Application Development (RAD) of an engaging graphical UI. This is the straightforward yet intriguing language that will have no muddled codes and engineers can move the controls that are as of now characterized. This is known as Object arranged programming language which is today collaborated with .NET and is called by VisualBasic.NET. Visual Basics in short is called as VBA. This is the broadly utilized programming language to create programming, application records just as ActiveX control documents. The same to that of other programming dialects, understudies who are doing their software engineering certificate should deal with Visual Basic tasks.
- Choice and Repetition structure: Similar to other programming dialects, circles and designs are imperative to learn inside and out about VBA. Assuming/else and if/else/are not many components that are utilized in the determination structure.
- Factors and constants: These are utilized to store various qualities. The variable qualities will continue changing with the execution level, while values identified with constants will continue as before.
- Operators and expressions: There are a wide scope of administrators that are utilized. Not many of them incorporate – <, >, <=,>=, <>, is, isn’t, and so forth
- Tools used to design application: VBA will offer you with the apparatuses that are needed to plan the application and site pages without coding.
Advantages of Visual Basic
- The construction of the Basic programming language is basic, especially concerning the executable code.
- VB isn’t just a language yet basically an incorporated, intelligent advancement climate.
- The VB-IDE has been exceptionally improved to help fast application advancement. It is especially simple to create graphical UIs and to interface them to overseer capacities given by the application.
- The graphical UI of the VB-IDE gives naturally engaging perspectives to the administration of the program structure in the huge and the different sorts of substances like classes, modules, methodology, structures framework.
- When altering program messages, the “IntelliSense” innovation advises you in a little popup window about the kinds of develops that might be entered at the current cursor area.
- VB is a part joining language which is sensitive to Microsoft’s Component Object Model.
- COM segments can be written in various dialects and afterward integrated utilizing VB.
- Interfaces of COM parts can be effortlessly called distantly through Distributed COM, which makes it simple to develop dispersed applications.
- COM segments can be installed in/connected to your application’s UI and furthermore in/to put away archives Object Linking and Embedding “OLE”, “Compound Documents”.
Applications of Visual Basic
- Data Related Tasks
- Doing Workbook Tasks
- Creating Pivot Table
- Adding User forms & Add-ins
- Process Automation
- VB Applications in MS Office – Access, Power-point, Excel, Outlook, Word, Publisher, Project, Visio.
