• Name of the control currently in edit,
• Empty string ("") if no control is currently in edit (no control has focus).

If the control currently in edit is not an edit control, <Result> is an empty string ("").

If the control currently in edit does not belong to the window that owns the code, the returned string has the following format: "<Window name>.<Control name>".
If the control corresponds to a table cell, <Result> contains the name of the column.
If the control belongs to a supercontrol, <Result> has the following format: <Supercontrol name>.<Control name>.
Caution: The case of the control name (uppercase/lowercase characters) corresponds to the one used when the control was created in the editor.

The case of controls belonging to supercontrols is not processed in this version.
