i am trying to insert value using dataset but its giving me an error of null point exception(object was not created) at run time
'my code is
Dim cnCustomers As OleDbConnection cnCustomers = New OleDbConnection Try With cnCustomers ' If .State = ConnectionState.Open Then .Close() .ConnectionString = cnString .Open() End With Catch ex As OleDbException MsgBox(ex.ToString) End Try Dim dt As New DataTable dt = dsstudent.Tables("survey1") Dim dsnewRow As DataRow ---- giving error at this point dsnewRow = dt.NewRow()
Error is :-(System.NullReferenceException)
tip is "Use the New keyword to create the instance. " at dim dt as new table
did it but not working
