The HL7+ Visual Studio API is a Class Library DLL for use in Visual Studio Windows Forms, Services, Command Line applications.
You can develop applications which are HL7 conversant using the API and distribute them royalty free to any computer running a valid HL7+ Client Installation. Unlike all of the other HL7+ features (Listener, Router, Notepad etc) the API DLL(s) do not install on the client computer with the Client Console software. To obtain the latest version of the library you simply contact us.
The technical documentation is too complex to go into on this short page so it's best to Open Online Help for the API and Other HL7+ Features.
