Programming in VB is a combination of visually arranging components or controls on a form, specifying attributes and actions for those components, and writing additional lines of code for more functionality. Programmers can create both simple and complex GUI applications. Like the BASIC programming language, Visual Basic was designed to have an easy learning curve. Ī dialect of Visual Basic, Visual Basic for Applications (VBA), is used as a macro or scripting language within several Microsoft and ISV applications, including Microsoft Office. Visual Basic 6.0 was selected as the most dreaded programming language by respondents of Stack Overflow's annual developer survey in 2016, 2017, and 2018.

In 2014, some software developers still preferred Visual Basic 6.0 over its successor, Visual Basic.

The Microsoft Visual Basic team still maintains compatibility for Visual Basic 6.0 applications through its 'It Just Works' program on supported Windows operating systems. On April 8, 2008, Microsoft stopped supporting Visual Basic 6.0 IDE. Programs written in Visual Basic can also make use of the Windows API, which requires external functions declarations. Over time the community of programmers developed third-party components. Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects.Ī programmer can create an application using the components provided by the Visual Basic program itself.

Microsoft intended Visual Basic to be relatively easy to learn and use. The original Visual Basic (also referred to as Classic Visual Basic) is a third-generation event-driven programming language from Microsoft known for its Component Object Model (COM) programming model first released in 1991 and declared legacy during 2008.

Similarly, you might write CLng(i)*y.īut that is a work-around and it is not the preferred solution.Learn. Instead, we must write CLng(200)*300 - or use the implicit type Long constant 200& and/or 300&, which can be confusing. The same thing happens if we write CLng(200*300). In your case, the problem arises because the expression i*y is evaluated as type Integer, before it is converted to type Long to be stored into j. More importantly, using type Single can lead to incorrect values when the variables are converted to type Double for example, storing into an Excel cell.Īnd as you learned, using type Integer can lead to 'premature' overflows. And even that is debatable, considering the huge main memories, cache lines and secondary storage in modern computers. But that should matter only with humongous arrays. The only benefit might be in memory space. In modern computers, there is no performance benefit to using type Integer and type Single.

In fact, in general, always use type Long for integer variables and type Double for non-integer variables. Solution is to declare i and y type Long.
