The Count property returns the number of parameters that are available to a particular type of texture fill.
Examples:
The following VBA example applies a texture fill to a rectangle and displays the number of parameters available to the fill.
Sub Test()
Dim s As Shape
Dim tf As TextureFill
Set s = ActiveLayer.CreateRectangle(0, 0, 2, 2)
Set tf = s.Fill.ApplyTextureFill("Vapor 2C")
MsgBox "Texture '" & tf.TextureName & "' has " & _
tf.Properties.Count & " parameters"
End Sub
