Shape.LayerCount Property (Visio)
Returns the number of layers to which a shape is assigned. Read-only.
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the LayerCount property to determine the number of layers to which a shape is assigned. It also uses the Layers property to add a layer to a drawing and the Name property to get the name of the current layer.

Set vsoShape = vsoPage.DrawRectangle(1, 5, 5, 1) 'Get the Layers collection. Set vsoLayers = vsoPage.Layers 'Create a layer named ExampleLayer1 and add the shape to it. Set vsoLayer = vsoLayers.Add("ExampleLayer1") vsoLayer.Add vsoShape, 1 'Create a layer named ExampleLayer2 and add the shape to it. Set vsoLayer = vsoLayers.Add("ExampleLayer2") vsoLayer.Add vsoShape, 1 'Verify that the shape has been assigned to 2 layers. Debug.Print "The shape is assigned to " & vsoShape.LayerCount & " layers." 'Get a reference to the first layer. Set vsoLayer = vsoShape.Layer(1) 'Verify by using the Name property. Debug.Print "Current layer name is """ & vsoLayer.Name & ".""" End Sub
