Programmatically setting engine to honor reference scales for selection.

Discussion created by matthewjhinds on Jun 23, 2011
A while ago I submitted a bug to ESRI that selections did not honor reference scales. This is now fixed and part of ArcGIS Desktop 10.

However - I need to do this programmatically. I set the option in ArcDesktop thinking that it may change a registry key that my engine application would recognize but no such luck.

Is there a particular API call that i should make to use this new feature?
