The Type property returns the type of the current effect. Depending on the type of effect, an object of the effect's properties (for example, blend, contour, distortion, and so on) is accessible. The Type property returns a read-only value of cdrEffectType.
Examples:
The following VBA example changes all blends attached to the selected shape so that they have only two steps.
Sub Test()
Dim s As Shape
Dim eff As Effect
Set s = ActiveShape
For Each eff In s.Effects
If eff.Type = cdrBlend Then
eff.Blend.Steps = 2
End If
Next eff
End Sub
