VB.net Data Relation Creation

I found the following example of creating a Data Relation. I get the error DataSet1 is not declared
What additional code do I need

http://msdn.microsoft.com/en-us/library/system.data.datarelation(v=vs.110).aspx

    Private Sub CreateRelation()
        ' Get the DataColumn objects from two DataTable objects  
        ' in a DataSet. Code to get the DataSet not shown here.
        Dim parentColumn As DataColumn = _
            DataSet1.Tables("Customers").Columns("CustID")
        Dim childColumn As DataColumn = DataSet1.Tables( _
            "Orders").Columns("CustID")

        ' Create DataRelation.
        Dim relCustOrder As DataRelation
        relCustOrder = New DataRelation( _
            "CustomersOrders", parentColumn, childColumn)

        ' Add the relation to the DataSet.
        DataSet1.Relations.Add(relCustOrder)
    End Sub

Hi murbro;

From the error it sounds like you have not created a DataSet object. In other words you need to instantiate a DataSet object and in that object add to the Tables collection the two tables Customers and Orders. Then to that same DataSet object add to the Relations collection the relationship you created to it. In your code you call this DataSet object DataSet1.
