ErrObject Class

The ErrObject module contains properties and procedures used to identify and handle run-time errors using the Err object.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public sealed class ErrObject

For more detailed information, see the Visual Basic topic ErrObject Module (Visual Basic).

The ErrObject module supports the Err object. For more information, see Err Object (Visual Basic).

This example uses the properties of the Err object in constructing an error-message dialog box. Notice what happens when you use the Clear method first: When you then generate a Visual Basic error with the Raise method, Visual Basic's default values become the properties of the Err object.

Dim Msg As String
' If an error occurs, construct an error message.
On Error Resume Next   ' Defer error handling.
Err.Clear
Err.Raise(6)   ' Generate an "Overflow" error.
' Check for error, then show message.
If Err.Number <> 0 Then
    Msg = "Error # " & Str(Err.Number) & " was generated by " _
        & Err.Source & ControlChars.CrLf & Err.Description
    MsgBox(Msg, MsgBoxStyle.Information, "Error")
End If
