Visual Basic is not case sensitive, which means that any combinations of upper and lower case letters in keywords are acceptable. Visual Studio automatically converts all Visual Basic keywords to the default capitalised forms, e.g. "Public", "If". C# is case sensitive and all C# keywords are in lower cases.
Visual Basic (VB), originally called Visual Basic .NET (VB.NET), is a multi-paradigm, object-oriented programming language, implemented on .NET, Mono, and the .NET Framework. Microsoft launched VB.NET in 2002 as the successor to its original Visual Basic language, the last version of which was Visual Basic 6.0.
There are tools to convert Visual Basic code to VB.NET, such as the Visual Basic Upgrade Wizard that was included in Visual Studio .NET 2002 and 2003. Conversion tools automatically insert a ByRef if necessary, preserving the semantics of the Visual Basic application.
Visual Basic .NET is Microsoft's successor to Visual Basic 6.0, and part of Microsoft's .NET ecosystem (which over time has sometimes been called framework and core). It is not backwards compatible with Visual Basic 6.0. An automated conversion tool exists, but fully automated conversion for most projects is not possible. [29]
The Is functions (also known as data information functions, [5] data inspection functions, [6] or data-testing functions [6]) are a set of functions in Microsoft's Visual Basic 6, Visual Basic for Applications, VBScript, and Visual Basic .NET. Several of them are also provided in Transact-SQL by the .NET Framework Data Provider for Microsoft ...
Small Basic supports basic data types, like strings, integers and decimals, and will readily convert one type to another as required by the situation. In the example, both the Read and ReadNumber methods read a string from the command line, but ReadNumber rejects any non-numeric characters.
COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y. Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)".
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
