I have a .NET engine application where I would like to show labels on a layer. I am not sure if labels is the correct term, perhaps annotations? Something which will show some information on the map such as a name for a feature. After searching for a couple of days now, I have only found out how to show the MapTips, not something which will show all of the time.
What I currently have is the following which doesn't work. Any ideas which piece I am missing?
Dim objLblEngineLyrProps As ILabelEngineLayerProperties
Dim objAnnoLyrPropsColl As IAnnotateLayerPropertiesCollection
Dim objAnnoLyrProps As IAnnotateLayerProperties
Dim objRGBColor As IRgbColor
Dim obj As IGeoFeatureLayer
'obj.DisplayFiel()
'objAnnoLyrProps = New LabelEngineLayerProperties
objRGBColor = New RgbColor
objRGBColor.Red = 0
objRGBColor.Green = 0
objRGBColor.Blue = 128
objLblEngineLyrProps = New LabelEngineLayerProperties
objLblEngineLyrProps.Expression = "STATE_NAME"
objLblEngineLyrProps.Symbol.Color = objRGBColor
objLblEngineLyrProps.Symbol.Size = 20.0
objAnnoLyrProps = TryCast(objLblEngineLyrProps, IAnnotateLayerProperties)
objAnnoLyrProps.LabelWhichFeatures = esriLabelWhichFeatures.esriVisibleFeatures
'objAnnoLyrPropsColl = objGeoFeatureLayer.AnnotationProperties
'objAnnoLyrPropsColl.Clear()
'objAnnoLyrPropsColl.Add(objAnnoLyrProps)
'objGeoFeatureLayer.AnnotationProperties = objAnnoLyrPropsColl
objGeoFeatureLayer.AnnotationProperties.Clear()
objGeoFeatureLayer.AnnotationProperties.Add(objAnnoLyrProps)
objGeoFeatureLayer.DisplayAnnotation = True
objAnnoLyrProps.DisplayAnnotation = True
AxMapControl1.ActiveView.Refresh()
