Question

I’ve got the following code and I’m trying to update a new db row with the information. I’m pretty sure i’ve done it this way before but it falls over with a ‘NullReferenceExcetption’ on the line

dtItemsFeed = taItemsFeed.GetData()

The code (trimmed down) is as follows:

Public Partial Class downloaditems

    Private dtItemsFeed As dsItems.ItemsFeedDataTable
    Private taItemsFeed As dsItemsTableAdapters.ItemsFeedTableAdapter

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        checkSite("http://www.tiag.me/whatever/header.html", "Header")

    End Sub

    Private Sub checkSite(ByVal URL As String, ByVal Type As String)

        dtItemsFeed = taItemsFeed.GetData()
        Dim rFeed As dsItems.ItemsFeedRow

        rFeed = dtItemsFeed.NewItemsFeedRow

      ### Code that loads items ###

        rFeed.HeaderCode = sourcecode
        rFeed.LastImport = System.DateTime.Now
        rFeed.Verified = "True"

        dtItemsFeed.AddItemsFeedRow(rFeed)
        taItemsFeed.Update(dtItemsFeed)

    End Sub

End Class

The data works when I look through with edit dataset so I know it is connecting

error:

Any help will be really appreciated. Tom

You have to create an object of dsItemsTableAdapters.ItemsFeedTableAdapter.

Private taItemsFeed As new dsItemsTableAdapters.ItemsFeedTableAdapter
