HELP - we need an expert please.... we lack experience to solve this problem

Sorry but we do not know how to fix this:

I pass the code that applies symbolization a layer of points with
ClassBreaksRenderer and "Quantities" and mode "Graduated Colors" from a .NET aplication, but at the end of the process, No way to update the table of contents.

If we use ArcMap, right click, properties on the layer and look at the symbolization form, ALL is perfect and if you click the OK button, all is well.
We refresh contents with
pMxDoc.UpdateContents()
and the activeView with
pMxDoc.ActiveView.Refresh()

Someone could tell us where we fail?

Have you tried refreshing the TOC directly (contentsview)
something like this:
for i=0 to pMxDoc.contentsviewcount -1
  pMxDoc.Contentsview(i).refresh()
next

Thanks Alexander.
It does not work.
I think it's a matter of classbreaksRenderer renderer update, but not like you can do.
Maybe some configuration errors and the legend has not updated why not ...

Hi,

try to change the order of instructions :

define the style before defining proprieties outline, outlinesize and outlinecolor, ...

Dim pSym2 As ISimpleMarkerSymbol
Set pSym2 = New SimpleMarkerSymbol
pSym2.Color = pColor2

pSym2.Style = esriSMSCircle

pSym2.Outline = True
pSym2.OutlineSize = 0.4
pSym2.OutlineColor = pColor3

pSym2.size = 5
pRender.Symbol(1) = pSym2

Finally, we have seen, how to correct the ClassBreaksRenderer error.
The time lost is the worst.
The solution has been not to create a new symbol with 'NEW SimpleMarkerSymbol' :

  Dim pSimpleRend As ISimpleRenderer

        pMxDoc = m_pDoc
        pLayer = pMxDoc.ActiveView.FocusMap.Layer(0)
        pFLayer = pLayer
        pGeoLayer = pFLayer
        pSimpleRend = pGeoLayer.Renderer
        Good -> pSFSym1 = pSimpleRend.Symbol     
        Bad -> pSFSym1= New SimpleMarkerSymbol

the rest of code is the same.

Thanks to those who have tried to help.
