VBScripting Fundamentals (Updated 2026)

Learn VBScript array handling with LBound and UBound to get lower and upper indices, IsArray to test arrays, and Erase to clear arrays through practical examples.

Use the vbscript filter function to extract array items that contain the letter a, print matches, and demonstrate the inverse with not matched criteria.

Explore two dimensional arrays in vbscript, using column index and row index with zero based indexes; learn to declare, populate, and access a phonebook example with column and row concepts.

Explore vb scripting conditional statements, including if, else if, else, and nested if, plus select case, and learn to handle message box responses to drive different workflows.

Explore the select case construct to handle multiple conditions, including examples with 100, 300, 400, 500, and 600 values, default else, and real-world usage like payment processing and weekday-based branching.

Handle message box responses by checking the return value against vbYes, vbNo, and vbCancel. Use these constants to drive conditional workflows or actions based on user selection.

Explore the for each loop and its difference from a for loop, iterating a one-dimensional array and printing each item with wscript.echo to demonstrate the construct.

Explore VBScript procedures, including sub procedures and functions, learn how functions return values, see hands-on examples with simple scripts, input, and a temperature conversion using a function.

Demonstrates VBScript procedures and functions, showing how to call add, subtract, multiply, and divide, include external scripts, and use the file system object.

Explore built-in VBScript string functions, including mid for substrings, length, reverse, lowercase, uppercase, replace, left, right, and trim variants.

Explore built-in string functions in vb scripting, such as replace, string compare, and end string to locate positions within a string, with case-sensitive and text compare options.

Understand how VBScript built-in functions null and empty differentiate uninitialized variables from truly empty values, and learn to check is empty and is null in sample code.

Explore VBScript built-in checks such as is numeric, is date, is array, and is object, with examples using variables and a file system object.

Learn to explicitly declare variables and use the file system object in VBScript to create folders with the create folder method, specifying paths and names.

Create a file system object, enumerate drives with a for each loop, and use the drive letter and count properties to display drive letters.

Explore how to obtain a drive object using the file system object and retrieve available space, free space, and total size for the C drive, converting bytes to gigabytes.

Learn to create a folder with a file system object in VBScript, using the create folder method and a folder exists check, plus message box feedback for creation or existence.

Learn to delete a folder in VBScript using a file system object and the delete folder method; the video shows checking existence before deletion and handling not found errors.

Move a folder using the move folder method by specifying a source and destination location, demonstrated with a file system object.

Learn the basics of the file system object model for files, including creating, opening, reading, writing, and closing with file system and file objects, text streams, and file modes.

Demonstrate writing to files using fso and file objects, creating or opening text files, and using write, write line, and write blank line with modes for reading, writing, and appending.
