11 VBScript Interview Questions (Sample Answers)
VBScript is a computer programming language that lets you make powerful tools for managing computers. If you are applying for a job as a VBScript developer or something similar, the interviewer may ask you both basic and advanced questions about this scripting language to see how much you know about it. If you know what the most common VBScript interview questions are and have answers ready ahead of time, you can answer them correctly and with confidence. This article talks about some of the most important VBScript interview questions and shows you how to answer them with tips and examples.
Sample answers to questions about VBScript asked at job interviews
Here are some common questions and answers about VBScript, as well as some tips:
1.What is VBScript and how do you use it?
This is a question that interviewers may ask at the start of the meeting. They want to know how much you know in general about VBScript. Talk about what type of programming language it is and how it can be used.
“VBScript is an Active Scripting language. It stands for Visual Basic Scripting Edition. It helps a lot when Microsoft Windows system administrators make tools to manage computers. It handles errors and runs subroutines by using the Component Object Model (COM). The Quick Test Professional (QTP) tool uses this simple scripting language to automate the scripts.
2. What types of environment does VBScript support?
This question is asked to see how well you can use VBScript in different situations. In your answer, list the three different types of environments where VBScript can be run.
Example: “VBScript can be run in three different environments: IIS, WSH, and IE” (Internet Explorer). Internet Explorer is the most simple of the three environments. In this hosting environment, most of what we do is run VBScript. IIS is Microsoft’s web server, while WSH is the environment that comes with the operating system.
3.What are the pros and cons of using VBScript?
Interviewers want to know if you know when to use VBScript and when to look for a different solution. First, say a few words about two or three of the most important reasons to use VBScript. Then, talk about a few things that are wrong with this language.
4.Procedures in VBScript are a way to do things. Talk about the different types of VBScript procedures.
This question checks how well you know how to write code in the VBScript language. Explain why procedures are used in VBScript. Talk about the Sub procedures and the Function procedures in your answer.
“VBScript procedures are the statements that are used to make and organize codes that can be used more than once. For example, if we need to add three numbers together in a script more than once, we can make a function or procedure for it. There are two kinds of procedures in VBScript: Function procedures and Sub procedures.
A Sub procedure is a set of statements between the Sub and End Sub statements. It can do what you tell it to do, but it doesn’t give anything back. It never needs to be different. A Function procedure is a group of statements that go between the Function and End Function statements. It can carry out commands and return a value. It might need help, but that’s not always the case.”
5. How do you tell a VBScript function which arguments to use?
This question is meant to find out how well you can use VBScript functions. In your answer, include both “by value” and “by reference” as ways to pass arguments. Explain briefly how these two ways of doing things are different from each other.
Example: “We can send a value to a VBScript function by using the ByVal and ByRef parameters. The argument is sent as the value when the ByVal parameter is used. The called procedure’s changes to the value of a variable are not kept in this method. ByRef uses a reference to send an argument. When this method is used, changes to the value of a variable are kept.
6. What rules are there for naming a variable?
There are rules about how to name a variable in VBScript. The people who are interviewing you want to make sure you know about them. Give a few important rules, like how long a variable can be and what kinds of characters can be used.
“The word “Dim” must be used to name a variable in VBScript. We can call a variable anything we want, but it’s best to call it something that makes sense. For example, instead of “ABC” or “XYZ,” you could use “student” or “salary” as a name. Also, we need to remember three important rules: a variable’s name must always start with a letter and shouldn’t have a period (.) in it. The name can’t contain more than 255 characters.”
7.What is a VBScript RegExp object, and what are its properties?
In VBScript, search is an important part of programming. Interviewers want to know how good you are at it. The InStr function and the RegExp object are two important ways to search in VBScript. Talk about the RegExp object’s properties and when and how to use it.
“RegExp object makes it easy to look for strings using regular expressions or special text patterns.” The RegExp object can search for and match patterns against things like file names and URLs, so we can use it to make sure data is correct. We need to make a RegExp object and use the to test a search string. How to check.
The three most important properties of a RegExp object are Pattern, IngnoreCase, and Global. Pattern is a string that defines the meaning of the regular expression. Both the IgnoreCase property and the Global property are Boolean. IgnoreCase tells you if a search cares about case or not. Global lets you know if you want to compare a regular expression to all possible matches in a string. Both IgnoreCase and Global start out set to “False.”
8.When should the Option Explicit statement be used, and what are the rules for it?
This question tests your ability to write an Option Explicit statement. After you explain how to use this statement in VBScript programming, give some important rules, such as where to use it and what happens to variables that aren’t declared.
Example: “The Option Explicit statement is used when we want the expression language to automatically check for Dim, Public, and Private Statements. It keeps us from making mistakes when we write code. When we try to use a variable that hasn’t been declared and the Option Explicit statement has been set, we get an error message.
The most important rule about the Option Explicit statement is that it must come before any other statements. Variables that haven’t been declared are automatically treated as variants if a module doesn’t have the Option Explicit statement. Once the Option Explicit statement is set, all variables must be named using a Dim, ReDim, Public, or Private statement.
9.What makes VBA different from VBScript?
People who are interviewing you might want to make sure you don’t mix up VBScript and VBA. Use the main differences between these two languages to show how well you understand the topic.
“VBA is short for the language Visual Basic for Applications. The VBA set includes VBScript. VBScript is not a full-fledged application development language like VBA. Instead, it is a scripting language. So, VBScript lacks many of the features that VBA has. In VBA, the user can choose the data type of a variable. This is not possible in VBScript. Another big difference between the two is this. VBA is a compiled language, but VBScript is not. This means that every time we run a script, a machine language reads the code and figures out what it means. Named arguments and early binding are not possible in VBScript, but they are in VBA.
10.What are the different types of Arrays that VBScript can use?
In VBScript, an array is like a list. It makes it easier to use one variable to get to more than one data value. This question is meant to see how much you know about Arrays in VBScript. Give a short explanation of the two kinds of Arrays in VBScript.
“There are two kinds of arrays in VBScript: arrays with one dimension and arrays with more than one dimension. It’s easier to understand and more common in scripts to use a one-dimensional array. A list with more than one dimension is called a multi-dimensional array. It can have up to 60 dimensions, but most arrays are only two dimensions.
11. When do you use the ReDim statement in VBScript?
Interviewers ask this important question to see how well you can write VBScript statements in real life. How does a ReDim statement work? You could also add a sentence about how important Preserve keyword is to your answer.
Example: “If we declare an array without specifying its size, we can use the ReDim statement to declare the array again and change its size.” By using the ReDim statement more than once, we can change the size and number of items in an array. By using the Preserve keyword, we can change the size of an array without changing what’s in it.
