Hi greco558,
Is the edit control inside a Window or a DialgoBox? If inside a Window, you should not have any problem. If inside a DialogBox, then you cannot change any children font (please see the Easy Code help File).
DialogBoxes are proportionally sized to its font, that is the reason why child controls always have their parent's font and cannot be changed. You just can change the DialogBox font and you will see how it and its children are proportionally resized.
Regards.
