This topic documents a feature of Visual Filters and Transitions, which is deprecated as of Windows Internet Explorer 9 and obsolete as of Internet Explorer 10.
Retrieves a value indicating the current progress of the transform effect.
Returns a value from 0.0 to 1.0 for the transform IDXEffect::Progress property.
When an effect transform is executed, it should use this value to control the effect's progress. This is typically only useful if your transform produces a transition effect. You can ignore this value if your transform is not a time-varying effect.
