Hai all ,
i am doing a VB.NET Windows Application .. In that i am populating the datagrid with the contents of an XML File (using dataset) . In the datagrid if i make any changes , it should be updated to the XML File . How can i do this ? I did the coding like this .
Dim DS as new DataSet
Dim dsl As New DataSetDim onm, oc, od As StreamFileNam = "OrgXML.xml"
DS.ReadXml(FileNam, XmlReadMode.DiffGram)
dsl = DS.GetChanges(DataRowState.Modified)
dsl.WriteXml(FileNam, XmlWriteMode.DiffGram)
But this code is not working .. I am getting the error that "Object Reference not set to instance of an object" How can i resolve this ? Any body plz help . its urgent.
