Hi folks,
By instantiating a new LineLabelPosition class, I've made the properties set correctly in label placement properties dialog now.
However, labels are not showing up automatically for my layer. I have to go to the Layer Properties dialog, simply open the Placement Properties dialog and click OK to close it, and click Apply to make the labels show up.
I've searched the forums and found that people had the same problem back in 2003. Since ESRI is so great in helping our community, I wouldn't believe that the problem has not been solved after 10 years. I must have missed something simple. Please help! my code looks like this now:
Private Sub CreateLabels(ByRef layer As IGeoFeatureLayer)
Dim labelClasses As IAnnotateLayerPropertiesCollection
labelClasses = layer.AnnotationProperties
Dim labelClass As IAnnotateLayerProperties = Nothing
labelClasses.QueryItem(0, labelClass, Nothing, Nothing)
Dim label1 As ILabelEngineLayerProperties = labelClass
CType(label1, IAnnotateLayerProperties).Class = "Label at start"
CType(label1, IAnnotateLayerProperties).DisplayAnnotation = True
label1.Expression = "[Line_Name]"
Dim overposterLayerProperties As IBasicOverposterLayerProperties4
overposterLayerProperties = label1.BasicOverposterLayerProperties
Dim label1Position As ILineLabelPosition = New LineLabelPosition()
label1Position.Above = False
label1Position.OnTop = True
label1Position.AtStart = True
overposterLayerProperties.LineLabelPosition = label1Position
overposterLayerProperties.LabelWeight = 3
overposterLayerProperties.FeatureWeight = 3
End Sub
Thanks
