If successful, an Int32 representing the zero-based position of the first unassigned editable position encountered; otherwise InvalidIndex.

The formatted string is composed of editable characters and literals copied from the mask. The editable character positions will either be occupied by the prompt character copied from the mask if they are unassigned, or with a valid input character if they have been assigned an input.

The FindNonEditPositionFrom and FindAssignedEditPositionFrom methods are complements of this method.
