What are the different types of error handling techniques?

Proofreading, testing, and feedback are all important steps in finding and handling syntax and logic errors. Programmers also use software debugging tools to find and correct these errors. Run-time errors are errors that occur when a program is in use.

What is the difference between error handling in VBScript and Goto?

The primary difference is that VBScript does not support the concept of error handling by continuing execution at a label. In other words, you cannot use On Error GoTo in VBScript. Instead, use On Error Resume Next and then check both Err.Number and the Count property of the Errors collection, as shown in the following example:

How do I handle errorerrors in ASP scripts?

What are syntax and runtime errors in VBScript?

Syntax errors, also called parsing errors, occur at interpretation time for VBScript. For example, the following line causes a syntax error because it is missing a closing parenthesis − Runtime errors, also called exceptions, occur during execution, after interpretation.
