The Err object contains properties and methods that allow you to obtain information about a single runtime error in a VBScript script. It also allows you to generate errors and to reset the error object. Because the Err object is an intrinsic object (which means that it’s part of every VBScript script you create) with global scope, you don’t need to create an instance of it within your code.
When an error is generated in your application—whether it’s handled or not—the properties of the Err object are assigned values you can then access to gain information about the error that occurred. You can even generate your own errors explicitly using the Err.Raise method. You can also define your own errors to unify the error-handling process.
When your program reaches an
On Error Goto 0
statement, the Err object is cleared and its properties
reinitialized. This can also be achieved explicitly using the
The string associated with the given error number
A context ID within a VBScript Help file
The path to a VBScript Help file
A long integer used to describe an error (i.e., an error code)
Either the name of the current project or the class name of the application that generated the error
Resets all the properties of the Err object
Forces an error with a particular error code to be generated
