hi,

I'm using globecontrol with bilboard layer, i'm trying to add an annotation to a layer, but does not appear, I see only a filled rectangle (the result in attach)

this is my code:

    Private Sub CreateLabel(ByVal pFLy As IFeatureLayer)

        Dim pGeoFLy As IGeoFeatureLayer
        Dim pAnnoLyrPropColl As IAnnotateLayerPropertiesCollection
        Dim pLblEngLyrProps As ILabelEngineLayerProperties
        Dim pAnnoLyrProps As IAnnotateLayerProperties

        Try

            pGeoFLy = pFLy

            pAnnoLyrPropColl = pGeoFLy.AnnotationProperties
            pAnnoLyrPropColl.Clear()

            Dim pPointPlacement As IPointPlacementPriorities = New PointPlacementPrioritiesClass
            pPointPlacement.AboveCenter = 0
            pPointPlacement.AboveLeft = 0
            pPointPlacement.AboveRight = 0
            pPointPlacement.BelowCenter = 1
            pPointPlacement.BelowLeft = 0
            pPointPlacement.BelowRight = 0
            pPointPlacement.CenterLeft = 0
            pPointPlacement.CenterRight = 0

            Dim pBasicOverposeterLayerProp As IBasicOverposterLayerProperties = New BasicOverposterLayerPropertiesClass
            pBasicOverposeterLayerProp.FeatureType = esriBasicOverposterFeatureType.esriOverposterPoint
            pBasicOverposeterLayerProp.FeatureWeight = esriBasicOverposterWeight.esriNoWeight
            pBasicOverposeterLayerProp.LabelWeight = esriBasicOverposterWeight.esriHighWeight
            pBasicOverposeterLayerProp.BufferRatio = 0
            pBasicOverposeterLayerProp.PointPlacementMethod = esriOverposterPointPlacementMethod.esriOnTopPoint 
            pBasicOverposeterLayerProp.PointPlacementPriorities = pPointPlacement

            pLblEngLyrProps = New LabelEngineLayerProperties

            With pLblEngLyrProps
                .Expression = "[Label]"
                .IsExpressionSimple = True
                .Symbol = CreateFontLabel()
                .BasicOverposterLayerProperties = pBasicOverposeterLayerProp
            End With

            pAnnoLyrProps = TryCast(pLblEngLyrProps, IAnnotateLayerProperties)

            With pAnnoLyrProps
                .AnnotationMinimumScale = m_SymbolProperties.Label_MinScale
                .AnnotationMaximumScale = m_SymbolProperties.Label_MaxScale
            End With

            pAnnoLyrPropColl.Add(pAnnoLyrProps)

            pGeoFLy.DisplayAnnotation = True

        Catch ex As Exception


        Finally
            pGeoFLy = Nothing
            pAnnoLyrPropColl = Nothing
            pLblEngLyrProps = Nothing
            pAnnoLyrProps = Nothing
        End Try

    End Sub

    Private Function CreateFontLabel() As ITextSymbol

        Dim pRGBColor As IRgbColor
        Dim pFont As IFont
        Dim pTextSymbol As ITextSymbol

        Try

            pRGBColor = New RgbColor

            With pRGBColor
                .Red = m_SymbolProperties.Label_Color.R
                .Green = m_SymbolProperties.Label_Color.G
                .Blue = m_SymbolProperties.Label_Color.B
            End With

            pFont = New SystemFont

            With pFont
                .Name = m_SymbolProperties.Label_Font.Name
                .Size = m_SymbolProperties.Label_Font.Size
                .Bold = m_SymbolProperties.Label_Font.Bold
                .Underline = m_SymbolProperties.Label_Font.Underline
                .Italic = m_SymbolProperties.Label_Font.Italic
            End With

            pTextSymbol = New TextSymbol

            With pTextSymbol
                .Color = pRGBColor
                .Font = pFont
                .HorizontalAlignment = esriTextHorizontalAlignment.esriTHALeft
            End With
            CreateFontLabel = pTextSymbol
        Catch ex As Exception
            CreateFontLabel = Nothing
        Finally
            pRGBColor = Nothing
            pFont = Nothing
            pTextSymbol = Nothing
        End Try
    End Function
