TEdit hint in OnKeyPress

[DrShepard 0]

Hello! I need to make hint appears in OnKeyPress event like in NumbersOnly-property (see attach). Because I use another input logic (not only numbers, but some special symbols too). I know that hint message is generated by Windows itself. What should I do?

in short: you can use BaloonHint for simulate this

see sample in StackOverFlow and adapt it for you case

I know about TBalloonHint component, but I want to make system hint as I said. See attach again.

good way (path) is verify the sources on Delphi for this components (teditnumber) and see like this event works

What you're searching for are called tooltips. Window with TOOLTIPS_CLASS class, TTM_* messages and so on.
