Custom Segment/Message Difficulties

Post by Milan Vydareny »

I am trying to learn how to create custom segments and messages for HL7 2.3. I downloaded the demo and discovered it uses 2.2 and 2.4, neither of which I have. Next, I took the sample code and modified all of the references to use 2.3 but it will not compile because of the final statement of the message INIT procedure. The statement is Parse(InitMsg) however the signature doesn't match the 2.3 version that also expects a second parameter of type TdiMessageInfo.

Can you post sample code that will successfully compile and execute using HL7 2.3?

Thanks for your help.

Hi,

Please download guide and see page 9
http://www.delphihl7.com/download/DelphiHL7_Guide.pdf
and demo contains custom segment and message example.
sample unit:

Code: Select all

unit uCustom;

interface
uses diHL7Base,diHL724, diHL7DT24, diHL7Grp24;
