Example not working

[Mark H]

Hi,

I'm very new to this but wondered if you can help.

I'm trying to get a basic example running within VS.NET 2008 but getting errors when I use the example code provided.

I'm using 2.0.2.0 DLL's as the newer versions were not working.

when i use the following:
PipeParser parser = new PipeParser();
NHapi.Model.V231.Message.QRY_R02 qry = new
NHapi.Model.V231.Message.QRY_R02();
qry.MSH.MessageType.MessageType.Value ="QRY";
qry.MSH.MessageType.TriggerEvent.Value = "R02";
qry.MSH.MessageType.MessageStructure.Value = "QRY_R02";
qry.MSH.FieldSeparator.Value = "|";
qry.MSH.SendingApplication.NamespaceID.Value="CohieCentral";
qry.MSH.SendingFacility.NamespaceID.Value = "COHIE";
qry.MSH.ReceivingApplication.NamespaceID.Value="Clinical Data Provider";
qry.MSH.ReceivingFacility.NamespaceID.Value=facility;
qry.MSH.EncodingCharacters.Value = @"^~\&";
qry.MSH.VersionID.VersionID.Value = "2.3.1";
qry.MSH.DateTimeOfMessage.TimeOfAnEvent.SetLongDate(DateTime.Now);
qry.MSH.MessageControlID.Value = messageControlId;
qry.MSH.ProcessingID.ProcessingID.Value="P";
XCN st = qry.QRD.getWhoSubjectFilter(0);
st.AssigningAuthority.UniversalID.Value = facility;
st.IDNumber.Value = mrn;
qry.QRD.QueryDateTime.TimeOfAnEvent.SetLongDate(DateTime.Now);
qry.QRD.QueryFormatCode.Value = "R";
qry.QRD.QueryPriority.Value = "I";
CE what = qry.QRD.getWhatSubjectFilter(0);
what.Identifier.Value = "RES";
return parser.encode(qry);

Im getting an error with this line:
XCN st = qry.QRD.getWhoSubjectFilter(0);
getWhoSubjectFilter is not available.

Hope you can advise or help.

Regards,
