What is meant by error handling in VBScript?

Ordinarily, all runtime errors that are generated by the VBScript engine are fatal, since execution of the current script is halted when the error occurs. Error handling allows you to inform the user of the problem and either halt execution of the program or, if it is prudent, continue executing the program.

What are the types of errors that can occur in VBScript?

There are three types of errors in programming: (a) Syntax Errors, (b) Runtime Errors, and (c) Logical Errors.

• Runtime errors.
• Logical errors.
• Err Object.

What causes a script to fail in VBScript?

This usually is the result of a syntax error. The script loads OK, but the program runs with unexpected results or fails when executing a particular function or subroutine. This can be the result of a syntax error that goes undetected at compile time (such as an undefined variable) or of a logical error.

What are two types of errors in VBScript?

We have two types of Errors in VB Script; they are VBScript Run-time Errors and VBScript Syntax Errors VBScript run-time errors are errors that result when our VBScript script attempts to perform an action that the system cannot execute.
