Typed Dataset with Enterprise Library

Is there a way to populate a typed dataset with the Enterprise library? I am getting a "System.InvalidCastException" exception.

TypedDS dsRuns =new TypedDS(); Database dbMMS = DatabaseFactory.CreateDatabase("TestInstance"); string cmd = "SELECT* FROM blah"; DBCommandWrapper cmd = dbMMS.GetSqlStringCommandWrapper(cmd); cmd.AddInParameter(":SDATE", DbType.String, datetimepickerDate.Text); dsRuns = (TypedDS)dbMMS.ExecuteDataSet(cmd);

Also, is there a way to cast a value dynamically while it's being populated into a dataset? I have a database time field that is in seconds after midnight. I want to convert this field into the timespan type. Thanks.
