How to zoom to points?

[JoshPorter]

What is the best way to zoom to a group of points and also a single point?  I have this code, but it doesnt always seem to work when there is only 1 point in the list.  Any tips?

Dim inclusiveExtent As New ESRI.ArcGIS.Client.Geometry.Envelope With {.SpatialReference = esriMap.SpatialReference}
Dim  mp As ESRI.ArcGIS.Client.Geometry.MapPoint
        For Each pt As Point In pPoints
            mp = mercator.FromGeographic(New ESRI.ArcGIS.Client.Geometry.MapPoint(pt.X, pt.Y))
            inclusiveExtent = inclusiveExtent.Union(mp.Extent)
            'esriMap.ZoomToResolution(esriMap.Resolution )
        Next
        esriMap.ZoomTo(inclusiveExtent)

For me the answer is to check the extent of the group of objects you have to zoom to. If this extent is too small or has a zero size you might want to create a kind of rectangle around an object of interest and zoom to it. I usually have a so called "zoom tolerance" setting defining a linear size of a point :)))
