The Name property returns the name of a texture-fill parameter.
Examples:
The following VBA example displays the name of the third parameter of the texture Fire Flies from the library Samples 9.
Sub Test()
Dim s As Shape
Dim tf As TextureFill
Set s = ActiveLayer.CreateRectangle(0, 0, 2, 2)
Set tf = s.Fill.ApplyTextureFill("Fire Flies", "Samples 9")
MsgBox tf.Properties(3).Name
End Sub
