[APP] TF3D Music Sleep Timer - Windows Mobile Apps and Games

I was getting utterly annoyed by the fact that the TF3D music player had no sleep funtion (turn of the music after a set amount of time). After doing some searches I was unable to find anything that suits my needs (anything at all in fact).
Now I have been using an application that pauses my music when I press the headset button for 1 second. What that app in fact does is: run an executable that somehow pauses the TF3D music player.
So in combination with 3 lines of mortscript I had my sleep application. Just run it (you will need to have mortscript installed, http://www.sto-helit.de/index.php?module=page&entry=ms_overview&action=view) and enter the amount if time (in minutes) after which you wan't the music player to stop playing. I usually set this to 1 hour, put on my headphones and fall somewhere within that hour to sleep. The players turns off and I won't wake up at 3 'o clock in the morning when I would rather be sleeping because of some loud track that starts playing.
The sddialer.exe file (which pauses the player) was developed by DYNAMIC+ (http://forum.xda-developers.com/showthread.php?t=502881). If the original developer has any problems with me redistributing a piece of his work, contact me.
The mortscript file (for the interested ones)
Code:
t = Input("Minutes until sleep","TF3D Music Sleep",1);
Sleep(60000*t);
Run("SDDialer.exe");
That's all there is to it, the pausing is handled by the SDDialer.exe file. which I did NOT write myself. So in case you find any error related to SDDialer.exe, you should contact DYNAMIC+ (the original dev). Because the SDDialer.exe file was originally written to be used in conjuction with a headset, it only works when a headset is plugged in! (don't know how bluetooth headsets are handled though)
Cabbed using the wonderfully simple QuickCab!
After installation you will have a new shortcut in your startmenu, just tap it, enter the amount of minutes and lay back. This works when your device is in sleep-mode, as well as in normal active mode. One remark: the SDDialer.exe file in fact toggles the music playback, so when you don't play music, and you set the timer to for example 10 minutes, the music will start playing after 10 minutes. Could be useful for a countdowncounter with music or something
Test results are ALWAYS appreciated

ill post you the requested source....
Code:
#define AUDIO_MANAGER_COMMAND_PAUSE 0x3
HWND GetAudioManagerWindow( )
{
return FindWindow( TEXT("AUDIO_MANAGER_ENG"), NULL );
}
BOOL IsAudioManagerPlaying( )
{
BOOL bIsAudioManagerPlaying = FALSE;
HKEY hkAudioManagerInformation;
if ( ERROR_SUCCESS == RegOpenKeyEx(HKEY_LOCAL_MACHINE, TEXT("Software\\HTC\\AudioManager_Eng\\information"), 0, 0, &hkAudioManagerInformation) )
{
DWORD dwType, dwStatus, dwCbStatus = sizeof(dwStatus);
if ( ERROR_SUCCESS == RegQueryValueEx(hkAudioManagerInformation, TEXT("status"), 0, &dwType, (LPBYTE)&dwStatus, &dwCbStatus) && dwType == REG_DWORD )
{
if ( dwStatus == 4 )
bIsAudioManagerPlaying = TRUE;
}
RegCloseKey( hkAudioManagerInformation );
}
return bIsAudioManagerPlaying;
}
LRESULT SendAudioManagerMessage( HWND hAudioManagerWnd, DWORD dwCommand )
{
return SendMessage( hAudioManagerWnd, WM_USER + 1, dwCommand, 0 );
}
Code:
if ( IsAudioManagerPlaying() )
{
HWND hAudioManagerWnd = GetAudioManagerWindow( );
if ( hAudioManagerWnd )
SendAudioManagerMessage( hAudioManagerWnd, AUDIO_MANAGER_COMMAND_PAUSE );
}

Is it possible to make this work with the speaker function? I quite like the speaker quality on my TP2.

Another feature I would love to see is the gradual decrease in volume. I have a sleep machine that slowly lowers the volume, so when the sound stops it isnt abrupt and possibly causing the person to wake.
Id be a willing beta tester...

sleep machine functionality for TF3D
Nice one, thank you!
I'd second the above suggestion for a gradual lowering of volume, it would be great to have some sort of sleep machine functionality.

Please not that I won't be adding any features/fix bugs on this 'application'. In fact: I don't even use TF3D anymore (Titanium + Nitrogen music player). But if it works for you, I always like to hear that.
