 |
|
Anyone know how to catch the key presses on them extended keys like "Pause", "Play", "Stop" and other keys associated with that?
I want to catch those so I can assign them to the XMPlay audio player.
Thanks,
~Garrett

Garrett,
Try using the GetAsyncKeyState with the following values.
| Code: |
%%VK_VOLUME_MUTE = $AD
# Windows 2000/XP: Volume Mute key
%%VK_VOLUME_DOWN = $AE
# Windows 2000/XP: Volume Down key
%%VK_VOLUME_UP = $AF
# Windows 2000/XP: Volume Up key
%%VK_MEDIA_NEXT_TRACK = $B0
# Windows 2000/XP: Next Track key
%%VK_MEDIA_PREV_TRACK = $B1
# Windows 2000/XP: Previous Track key
%%VK_MEDIA_STOP $B2
# Windows 2000/XP: Stop Media key
%%VK_MEDIA_PLAY_PAUSE = $B3
# Windows 2000/XP: Play/Pause Media key
LoadLib user32.dll
%R = @lib(user32,GetAsyncKeyState,INT:,INT:%%VK_MEDIA_PLAY_PAUSE)

You will need to put GetAsyncKeyState in a tight loop to capture this way.
Information about the GetAsyncKeyState function can be found here http://msdn.microsoft.com/en-us/library/ms646293.aspx
I found the virtual keycodes here http://msdn.microsoft.com/en-us/library/ms645540(VS.85).aspx
But this will not get the state of those keys globally... I think CodeScript had a list of keyboard codes that would work with the VDS @HOTKEY() function which will trap key states globally. If I get a chance I will see if I can translate these Virtual Key codes to Scan codes.

That is what I needed, and it mostly works, even when vds is not the app in focus at the time.
Mute and volume up didn't want to work for me though.
Thanks
