There's an example in C# of how to use the IFeatureProgress interface here:

http://resources.arcgis.com/content/kbase?fa=articleShow&d=34908

Basically you need to create a class which implements this interface. Then the following methods are the ones you're interested in:

IFeatureProgress::FeatureClassName - IFeatureProgress_set_FeatureClassNameEventHandler
IFeatureProgress::MaxFeatures- IFeatureProgress_set_MaxFeaturesEventHandler
IFeatureProgress::FeatureClassName - IFeatureProgress_set_StepValueEventHandler
IFeatureProgress::StepValue- IFeatureProgress_StepEventHandler

Hope this helps.

Hi
Glad I've been able to help. All the methods you need to implement are in the link in my post above. So you need to implement the method IFeatureProgress::IsCancelled and return false instead of the line

mpChkOutIsCancelled = New IFeatureProgress_get_IsCancelledEventHandler(Addre ssOf GetCheckoutIsCancelled)
