Message creation question

[JerryB123]

Hello,

I am trying out DelphiHL7 to create HL7 messages. I do not see any examples of using multiple parameters, so I do not know if I need to explicitly create other objects or if they are created automatically or if there is some other mechanism that needs to be invoked.

Do you have an example of creating a complete TdiORU_R01_26 message with multiple reading results? (BP: 120/80@75, Temperature: 98.6°F, SpO2: 98%) That would be very helpful in showing me how to use DelphiHL7 components to create messages that I need.

Thank you.
Jerry

Hi,
Please check this link : http://www.delphihl7.com/?action=sample
The following codes are taken from that page.

First example is "Parsing Message" ORU_R01 for V 2.2

Code: Select all

uses diHL722, diHL7DT22, diHL7Grp22;

procedure TForm1.diMessageParseClick(Sender: TObject);
var
    msg : TdiORU_R01_22;
    Patient : TdiPN_22;
    observation : TdiORU_R01_PATIENT_RESULT_ORDER_OBSERVATION_OBSERVATION_22;
    MsgStr : AnsiString;
    i : integer;
begin

    MsgStr :=

For create a message :
You can create HL7 message using AsString property or XML message using AsXML property

Code: Select all

procedure TForm1.bGenerateXMLMsg(Sender: TObject);
