Little bit of a pickle with My.Settings and Datatable...

[Herman]

        Using dtTemp As System.Data.DataTable = CType(My.Settings.dtScheduledJobs, System.Data.DataTable)
            dtTemp.Rows.Add(New String() {0, _
                                          GetDatabaseName(), _
                                          cmbFrequency.SelectedText, _
                                          "", _
                                          tpDate.Text & " " & tpTime.Text, _
                                          "", _
                                          txtSavePath.Text, _
                                          GetConnectionString()})

            My.Settings.dtScheduledJobs = dtTemp
            My.Settings.Save()
        End Using

What I am trying to do here is read the content of a datatable object stored in My.Settings, add a row, and write it back. The .Add method throws a null reference exception however, and I am unsure why.

Suggestions?

If there's a NullReferenceException then there's a null reference. Which reference on that line is Nothing?

Turns out the Nothing was the columns collection in the datatable... I got it all fixed up now though, thanks anyways.
