c# - How to capture volume control keys in IBM/Lenovo ThinkPad? -


i have ibm thinkpad notebook , pcmcia sound card.

volume control works integrated sound card. want fix somehow writing small application.

i tried find codes of these keys this:

private void form1_keyup(object sender, keyeventargs e) {     labelkeycode.text = e.keycode.tostring(); }

however not working. im not getting codes. looks these keys not part of "keyboard device".

note: code code preview, in application want use winapi global keyboard capture.

how can capture these keys?

edit:

i tried reverse-engineer little, , browsed "hkvolkey.dll" (file ibm hotkey software) dependency walker, found 2 function names there: registervolumehotkey , deregistervolumehotkey.

i think approach wrong. have @ this: disable keyboard globally wpf window

as input keys might registered, not regular input control keys.

maybe of use more direct approach: http://naudio.codeplex.com/

naudio open source .net audio , midi library, containing dozens of useful audio related classes intended speed development of audio related utilities in .net.

i've written small piece of code once mute volumes using naudio: mute windows volume using c#

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
