Val() function which also parses a null value while converting into double (In c# Convert.ToDouble() is used to convert any object into a double type value, but which throws an exception in the case of a null value) CInt, CStr, CByte, CDbl, CBool, CDate, CLng, CCur, CObj and a wide variety of conversion functions built into the language
The same is true of VBScript, where any string that can be converted to a currency value in the current locale is considered to be numeric. VBScript does not, however, consider dates and times to be numeric. [27] IsObject(expression) This function determines whether the expression passed as its argument is an object rather than a value.

Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...
The VBScript language is modeled on classic Visual Basic. [13] Notable features include: A "procedure" is the main construct in VBScript for separating code into smaller modules. VBScript distinguishes between a function, which can return a result in an assignment statement, and a subroutine, which cannot.
VBScript is the default language for Active Server Pages. It can be used in Windows scripting and client-side web page scripting. It resembles VB in syntax, but is a separate language—executed by vbscript.dll instead of the VB runtime. ASP and VBScript should not be confused with ASP.NET, which uses the .NET Framework for compiled web pages.
Both Visual Basic 6 and Visual Basic .NET automatically generate the Sub and End Sub statements when the corresponding button is double-clicked in design view. Visual Basic .NET will also generate the necessary Class and End Class statements. The developer need only add the statement to display the "Hello, World" message box.
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 is a name for a family of programming languages from Microsoft. It may refer to: Visual Basic (.NET), the current version of Visual Basic launched in 2002 which runs on .NET
