Colorier des polygones

Voici comment affecter une couleur à un polygone dans Mappoint:
Dim adoCn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim dbPath As String
Dim strQry As String
Dim i As Long
Dim lngPop As Long
Dim oShape As MapPoint.Shape


'Recupération de la valeur de palette qui est dans le fichier Kanalyse.conf , lu au démarrage
Select Case strPalette
    Case "vert"
        color1 = mpLightGreen
        color2 = mpBrightGreen
        color3 = mpSeaGreen
        color4 = mpGreen
        color5 = mpDarkGreen
    Case "bleu"
        color1 = mpPaleBlue
        color2 = mpSkyBlue
        color3 = mpAqua
        color4 = mpBlue
        color5 = mpDarkBlue
End Select

dbPath = "chemin de mabase"
'j'utilise une base access qui stocke la données attributaire
adoCn.Open ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " & dbPath & ";Persist Security Info=False")
'selection de la table qui contient des données à l'iris
strQry = "SELECT " & strTable & ".IRIS, " & strTable & ".val " _
& "From " & strTable & " ORDER BY " & strTable & ".val ;"
rs.Open strQry, adoCn, adOpenStatic, adLockOptimistic

rs.MoveLast
rs.MoveFirst
For i = 0 To rs.RecordCount - 1
    lngPop = rs.Fields(1).Value
    'ici le polygon mappoint , pour etre reconnu doit avoir un code iris valide
    Set oShape = frmCartoDso.MappointControl0.ActiveMap.Shapes(rs.Fields(0).Value)
    'oShape.Fill.ForeColor = vbBlack

    rs.MoveNext
Next i
'End If
End Function
