Remarks
The IRowChanges interface allows clients of a row object to determine the values that were changed for the row object within a Store cycle. Once the Store method call returns to the calling application program, the information regarding the values that were changed is cleared and is no longer available. This information may be made use of by a custom object in its OnChanged or OnNew implementation and also by a related object in its implementation of the RelatedObjectChanged method.
The ValueChanged method returns true if the value for the specified field was changed since the last call to Store on the row object.
The OriginalValue method returns the value for the specified field as it existed prior to the first update made to the row object since the last call to Store on the row object.
