Oracle Forms

Forms 10g, win2k

Before you get fired up to flame me that this has been asked before, this is not the garden variety "need to capture keystroke" question!

I need to capture keystrokes, including control characters, as they are typed. Ideally I would like to get an ASCII value when a single keystroke is typed. I want to avoid timers for the obvious performance reasons. I already tried a couple of javabeans with no success:

keyfilter.jar
This comes with the forms demo. Does NOT fire an event on a keypress. Returns a key_code, key_character and a key_modifier. Returns the same key_code for upper and lower letters (the uppercase value), but by examining the key_character and key_modifier (ctrl, alt, etc) I can determine the control character. If only it fired an event on a keypress. I tried to simulate it firing an event by making a 1 character field with the automatic skip set to yes and putting my code to examine the keystroke in the next field's WHEN-NEW-ITEM-INSTANCE trigger. However, entering a control character does not cause the automatic skip to work. Also, some control combinations are set in the fmrweb.res file and are interpreted by forms (ctrl-H brings up help) before I can catch it.

keytyped.jar
This is from the example provided by our friend Francois here:
http://forms.pjc.bean.over-blog.com/article-1827045.html.
It DOES fire an event on a keypress. Interestingly, it returns the same value for both upper and lowercase letters too, but it returns the lowercase value. I tried to enter control characters and the value for the lowercase letter is returned or a value of 191.

Does anyone have a modified version of the keyfilter bean that fires an event on a keypress? Or perhaps another bean I can try? Is there a mechanism to make this program use its own fmrweb.res file in order to turn off default forms control characters?

Thanks for your attention,
