I'm trying to control volume by Held down Media Button like the same in Headset
Droid<https://market.android.com/details?id=tvk.headvol&feature=search_resu....>(reset and rise volume). I'm doing my best, but can't to realize it
normally. Can you help me?

How are You doing (it)? как Вы это делаете? :-D

Можно по русски? =)
Когда зажимается кнопка - громкость сбрасывается до 4 (из 15), кастомная
переменная (например %HDVC) получает значение 1 . Когда отпускаю -
переменная получает значение 0 (в Exit Task)
Пока значение 1 идет рост громкости с проверкой %HDVC=1 на каждом шаге. Как
только %HDVC=0 → Stop
Это завершает рост громкости, но изменения не сохраняются =(

No Russian in group, please. :) That was a joke

paste related profile&task description. what kind of headset do You using?

Here is alternative solution. It requires Hold Media button for 1 sec to
start rising Volume over ring 0:1:13 and short click one to stop it. I
think after release of button for giving other apps to play with media
buttons we should Grab it again in some case....

A bit tuned version. There is no need to Grab keys with native HTC player
and BeyondPod. They shares Hold event as well. Plus my favorite method to
stop task - Abort Existing Task in collision setup with Stop-If action at
the beginning. So, now it rises volume while button held and stops when
released.

Two strange things (for Pent's attantion):
1. These profile and it's tasks are not catched in Run Log at all! Not
appears it %PACTIVE and %TRUN as well
2. Variable Add starts from non-zero and doesn't wrap, so VOLM rises to
maximum and stops.

Any suggestions?
