An unhandled exception of type 'System.Configuration.ConfigurationException' occurred

Hello Thearon,

I am using an older book of yours, ISBN: 0764568000, to learn about vb.net, sql server, access, and maybe oracle. I've typed most of the code for TimeTracker and it was compiling fine until I began receiving this exception:
(An unhandled exception of type 'System.Configuration.ConfigurationException' occurred in system.dll
Additional information: Unrecognized configuration section appSetting)

This is occurring Public Class DALBase in the procedure:

Code:

Public Sub New()
        '   get the connection settings from the application configuration file
        Dim objAppSettings As Specialized.NameValueCollection
        objAppSettings = ConfigurationSettings.AppSettings()
        '   build the SQL connection string and initialize the Connection object
        Connection = New OleDbConnection("Provider=" & objAppSettings.Item("Provider") & ";" & _
                                         "Data Source=" & objAppSettings.Item("Data Source") & ";")
        objAppSettings = Nothing
    End Sub

Do you know what is causing this??

Thank you,
Jim
