Remarks

The QueryPositions method queries the positional values along the source feature from which this edge element was created.  The position values range from 0.0 to 1.0, where 0.0 is at the from-end of the feature and 1.0 is at the to-end of the feature.

If the Direction property is esriNEDAlongDigitized, then the fromPosition value will be less than or equal to the toPositionValue.  If the Direction property is esriNEDAgainstDigitized, then the fromPosition value will be greater than or equal to the toPositionValue.
