Err.Source Property

Err.Source Property

---

Class

Microsoft.VisualBasic.ErrObject

Syntax

 Err.Source 

Description

A read/write string property containing the name of the application or the object that has generated the error.

Rules at a Glance

• When a runtime error occurs in your code, the Source property is automatically assigned the project name (that is, the string that is assigned to the project's Name property). Note that this is not necessarily the filename of the project file.

• For clarity of your error messages, when you raise an error in a class module, the format of the source parameter should be project.class .

Programming Tips and Gotchas

Knowing what type of error has occurred within a program without knowing where the error was generated is often of little use to the programmer. However, if you enhance the standard Source by adding the name of the procedure, you can cut your debugging time dramatically.
