confirm window for analog

hi all,
using a zenon 7.10 5560.
I 'd like to make a confirm winodw when writing a set value.
now, under properties of numberic value > write set value
> write set value via : element.
so, on the Runtime, when changing a set value,
after click the numberic element and write a value customer want,
and then, we have to be push the "Enter" button.
just pushing the "Enter" button, confirm window is displayed.
and then, they can select a "ok" and "Cancel" on the confirm window.
any idea ??
