HL7Connect COM Library

HL7Connect includes a COM library. The COM library offers a set of HL7 v2 messaging and CDA document services that are useful for healthcare applications. The services include message/document:

  • Parsing
  • Encoding
  • Building
  • Scripting
  • Analysis

Consult the API documentation for further information.


No license, either developer or run-time, is required to use the COM Library. It is free for any of kind of use. The COM library and a standalone COM Library installer is included in any installation of HL7Connect, and can be installed separately.

Server Support

The HL7Connect COM Library can be configured to connect to the HL7Connect server at startup. In this mode, the COM Library offers an additional series of services that are extensions of the HL7Connect server itself, most importantly including the ability to send and receive messages or documents. The server needs to have an Enterprise Edition License for this use.

In addition, the HL7Connect Type Library includes a number of server side interface declarations. HL7Connect users can implement these interfaces in any COM-capable language, and handle message/document sending/receiving and other HL7Connect extensibility events in their own code.
