I didn't find any examples in the documentation and I could not figure out in the framework where to utilize this method. Any assistance would be appreciated.

Ultimately, you don't want the business object to get the user name from the environment since that breaks the rules of n-tier programming. Ultimately, if this is something you want to do for all of your business objects, and an approach that works for both Web and Windows apps, you can create a constructor in your business objects that accepts the user name (or id??) and then have the business object store the value in a property for later use. This property can be defined at the ABusinessObject level so it is inherited by all your business objects.

When you're ready to save, you can then retrieve this value from the business object property and then store it in the business entity (or DataTable if you aren't using entities). You can put this code in one of the business object's HookPreSave methods.

Best Regards,
