Hi,

How do I modify the code below to export the data from the data table XML?

        Dim GGB As String
        GGB = "'" & ComboBox2.SelectedItem & "'"
        Dim SearchCriteriaZ As String = "COUNTRY IN (" & GGB & ")"
        xmlPath1 = System.IO.Path.Combine(Application.StartupPath + "\AOP40.xml")  'grid1
        dtsetcol1.Clear()
        dtsetcol1.ReadXml(xmlPath1)
        Dim FilteredDTA As DataTable
        Dim DVA As New DataView(dtsetcol1.Tables(0), SearchCriteriaZ, Nothing, DataViewRowState.CurrentRows)
        DVA.Sort = "SN"
        FilteredDTA = DVA.ToTable
        Me.C1Screen1.DataSource = FilteredDTA
     

Open in new window


Thanks,

Victor

Hi,
I tried it but it didn't  work. Seem to work from a dataset but not a table, is there away to convert the data table to a dataset to use the code.

Our Dev teams are like yours. They’re continually cranking out code for new features/bugs fixes, testing, deploying, testing some more, responding to production monitoring events and more. It’s complex. So, we thought you’d like to see what’s working for us.

Are you still programming for framework 1.0 or 1.1

WriteXML was not supported on a DataTable in these versions, but has been since 2.0 (Visual Studio 2005).

If you are still on an old version, do yourself a favor and move to a newer version of Visual Studio and the framework. You can have the Express version for free if you program only from time to time, but if you are a professional and work in a group of 5 programmers or less, you can get the Community Edition, that is a free edition of the Professional.
