How to check whether a feature is changed on attribute or changed on shape?

[SuiHuang]

Hi Everybody:

    I am working on an ArcMap 10 extension and I am tryting to do some automatically attribute manipulation when the shape of the feature is changed. I found that if I just implement the IEditEvents_Event.OnChangeFeature event then I will need to check whether the shape is changed or just the attribute. How can I do that?
    Thank you!

Hi Everybody:

    I found that IFeatureChanges will work for me.
    Is there any better way? Is there any limitation for this way?
    Cheers!

I can't find where to tell which attributes changed. I get the new values but can I get any old values other than the geometry?

Thanks,
