I am working on an ArcObjects tool (for Desktop application) that was before for V9.3, but failed in V10.0.  I received such an error message:
Error HRESULT E_FAIL has been returned from a call to a COM component.  ???
at        mFeatCur = mFeatClass.Update(mQFeatures, false);
where   mFeatClass is an IFeatureClass, mFeatCur  is  an  IFeatureCursor.
I checked the references and found nothing is missing.
If you have any idea for this issue, please share.  Thanks.
