and methods that allow you to obtain information about a single runtime error in a Visual Basic program. The Err object also lets you generate errors and reset the error object. Because the Err object is an intrinsic object with global scope (which means that it is part of every VB project you create), you do not need to create an instance of it within your code. When an error is generated in your application — whether it is handled or not — the properties of the Err object are assigned values that 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 Exit Function, Exit Sub, Exit Property, Resume, or On Error statement, the Err object is cleared and its properties reinitialized. This can also be done explicitly using the Err.Clear method. Public Instance Properties Property name Description Description The

The Err object's properties are reset to zero or zero-length strings ("") after an On Error Resume Next statement and after an Exit Sub or Exit Function statement within an error-handling routine. The Clear method can be used to explicitly reset Err. Note Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Visual Studio Settings. To retrieve information from an error objectYou can filter for specific errors. This example checks to see if the error is a FileNotFound error and reacts if it is. VB Copy If Err.Number = 53 Then MsgBox("File Not Found") End If You can also examine specific properties of the error object, such as Description, Erl, HelpContext, Helpfile, LastDLLError, Number, and Source. This example displays the description in a message box.
