basically, you assign the results to a DataSet; since a DataSet contains a collection of DataTable,s you can then iterate through each datatable, or assign, say a grid's datasource to DataSet.Tables[0], for example.
Dim ds As New DataSet
ds = SqlHelper.ExecuteDataset(Me.ConnectionString, CommandType.Text, sql)
For Each dt As DataTable In ds.Tables
'do something with the results, like export?
