What is the difference between vba and vbscript

Unlike Visual Basic and Visual Basic for Applications, in which the developer can define the data type of a variable in advance, all variables in VBScript are variants. There are subtypes to handle different types of data, and you can use these as you would the traditional data types in Visual Basic.

For more information, see Chapter 3. That means that the code that you write is interpreted into machine language each time you run the script, which imposes a definite performance penalty. Visual Basic programmers who have worked with the language for a long time can remember when Visual Basic was also an interpreted language.

Is this a big deal for VBScript? And code portions whose performance are particularly sensitive can be removed from the VBScript code and placed in a compiled COM component that the VBScript code instantiates.

Because variables are untyped and code is not compiled, all external objects instantiated in VBScript code are necessarily late-bound. This has a number of implications. Generally, a scripting language can not be used to create a full-fledged binary application and it can not be compiled down to a executable binary file. NET are. They're all different, some of them dramatically so. Not going to repeat what other answers already indicate, but the following differences are missing from the other answers:.

VBScript code doesn't need procedure scopes: it can be written as a [drumroll] script that just executes a bunch of procedural operations top-to-bottom. In VBScript everything variables, function return values, etc. It is illegal to declare an explicit type when declaring a variable.

The As keyword is illegal! VBScript is a "lightweight" subset of Visual Basic with limited syntax that is used for scripting purposes like routine task automation rather than application development. While Visual Basic code is compiled into binary executables, VBScript code is interpreted and runs within a host environment e.
