I must be the only one around that wants to make a Windows program just for the desktop using VB .NET and XML. And do not want to use SQL, OLEDB, ODBC, Access. I just want to use XML to store the Data, read the Data into a DataGrid, add or delete rows, and edit the rows then write the changed Data back to the file. So far I have an XML file, an XSD file, a form with a DataGrid, I have made a DataSet with the following line of code Dim dsContacts As New DataSet("contacts") I placed a mainmenu control on the form and use menuitem3 as below. Which populates the DataGrid. Now I understand I have to have a DataTable to be able to do anything with the data. I have read the help files in VB .NET but the more I read them the more confused I get. Can someone please tell me how to make a DataTable using the information below to construct it? 'This code populates the DataGrid Private Sub MenuItem3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MenuItem3.Click Me.DataGrid1.Visible = True 'Reads the data from the contacts.xml file dsContacts.ReadXml(Application.StartupPath & "\contacts.xml") With DataGrid1 .DataSource = dsContacts .DataMember = "contacts" .CaptionText = .DataMember End With End Sub ------------------------------------------------------------------------------------------------------------------------ This is the file containing the Data. The name of the file is contacts.xml.
