1. Beep on Enter in EditText controls
- Posted by jc at cowgar.com
Aug 29, 2003
Greetings.
I have created a onKeyUp handler to capture an Enter key press that will do
a query on the database to see if a duplicate record exists. This works
great but what I am having problems with is that Windows will cause a Beep
or Ding in the speaker.
Is their anyway to stop this from happening on this field?
Thank you,
Jeremy

Instead of a KeyUp event, trap the KeyPress event and when you finish processing
the VK_ENTER key, call returnValue(-1) to signal that you want Windows to ignore
the key.
procedure onKeyPress(int self, int event, seq parms)
if parms[1] = VK_ENTER then
-- Process the Enter key
. . .
returnValue(-1)
end if
end procedure

as your final statement before your routine exits, call returnValue(-1)
which will prevent Windows from seeing the Enter key. You can also use this
to forward a different key to Windows, such as creating a password field by
calling returnValue('*') for every key press.

Actually, the returnValue(xxx) technique only applies to w32HKeyPress =
event, and not the KeyDown or KeyUp events.
