Volume buttons override problem on WM 2003 SE phon

[Guest Serg]

I have problem with mpx220 (and other SE phones, for example, I-Mate SP3, I-Mate SP3i): I can’t trap press/release of volume buttons separately. I am using SHCMBM_OVERRIDEKEY message to override default action of this keys. But WM_HOTKEY messages can be received only simultaneously: only if I press and then release volume up/down buttons. If I press and hold volume down button no messages was send until I release this button. If I press and hold volume up button, speech recognition (or voice recorder) program was started. I am trying SHCMBM_OVERRIDEKEY for VK_TRECORD button, but with no result.

May be anybody know how this problem can be solved on SE phones? (Override default action of volume buttons, receive separately key down/up events for this keys and don't start speech recognition (or voice recorder) program if volume up button was not released).

Thanks.

you are aware that some hardware only gives instantaneous keystrokes, either on initial down or release on the volume buttons?

original SPV was a readable down state, and readable release - C500's work a different way as the hold down has a secondary function
