In your EasyHL7 solutions you should always make it a point to check the .IsRegistered property in all of your initialization code. If the objects are not registered, the components will not work. The components determine if they are registered by reading a license file from the folder where the DLL is physically located. Every license file is only valid for that particular computer.

Q: Does this mean that I have to purchase the components before I can test or evaluate them?

A: Absolutely not.

There are 3 types of license files.

1) A DEVELOPMENT license. This is the license which you purchase from the HermeTech International Ltd EasyHL7 website (www.hermetechnz.com). It is called EasyHL7.lic and the file is only good on a single computer. You purchase DEVELOPMENT licenses for your developer's computers as needed.

2) A RUNTIME license. If you own a DEVELOPMENT license you can create RUNTIME licenses using the EasyHL7 License Manager or also directly from your code using several built-in methods (an internet connection is required for that). See ActivateFromClipboard, ActivateComputerForDemo, ActivateComputerForRuntime.

3) A DEMO license. Any EasyHL7 customer who has registered on our website (which you had to do to download the software) can create DEMO licenses. Again, you can do this using the EasyHL7 License Manager or directly from code over the internet. DEMO licenses have a 30-45 day expiration period (You can test when a License expires by calling the .LicenseExpiresOn or .LicenseExpired property). If you own a DEVELOPMENT license you can create an unlimited number of DEMO licenses, if not you can create DEMO licenses for up to 5 different computers (if you need more, contact customer service).

RUNTIME and DEMO licenses will be named <.ProductID>.MC.lic and one is required for each computer.

Owners of a DEVELOPMENT license may generate RUNTIME licenses for up to 20 different computers with their initial purchase of their development license. Additional 'packs' of available RUNTIME licenses must be purchased for a very nominal fee (our commitment is for your cost to never exceed US$5.00 per license). See the EasyHL7 Website for more information.
