Thank you Jurgen for the valuable information. I would not have been able to get my plugin to do the update I need to have it with out your kindness.
Is there anywhere such items are explained? Is that part of the api doc through inheritance? If so I would try to look into it more and do my homework so that I am not a asking too many questions. But just the same, I am also ashamed to ask, and take your valuable time and I spend quite a bit of my time wandering around. Thank you Jurgen again and I also say, God bless you.

Changes to the feature buffer filled by QgsVectorLayer::nextFeature() are not propagated to the layer. Use QgsVectorLayer::changeAttributeValue() [1].
