This document will explain how to use the HL7 ActiveX Control v1.0.  The HL7 ActiveX Control is used to simplify the complicated task of parsing HL7 messages.   The HL7 control is based on the work that Allen Rueter did with his implementation of hl7imexa. The HL7 control is used by application developers who what to process HL7 messages in an easy and efficient manner. The control supports the creation of HL7 messages and the parsing of HL7 messages. The HL7 ActiveX control has support for TCP/IP, so the developer can send and receive HL7 messages over the network. When using TCP/IP support, the developer has the ability to include envelope support where the HL7 message has a start character indicator and an end character indicator. Below is a list of options:
