Hi!

These methods require running of each forms to store control sources in the DBF file. Really only project scan required in development environment for that (Imagine change of classes, running each form and than change classes back).

As about use of Assign method - it is pure way of event dispatching for all form objects and all container objects. I used this, for example, to refresh properly grids on the form after grid lost focus, or se focus to the control that have special control source (for example, required field). Its very nice that SetAll fires assign method.
