Method 1 (Preferred Method):Chris Dziemborowicz's Orzeszek Timer.exe supports Command Line, but I couldnt get the Alarm to sound..
Chris said he would modify it in the next few days to read Sounds from the .exe files directory, instead of the sounds folder...
if that works, I'll post that one up here, since its an awesome timer.. maybe some of you guys will have better luck
He said he created it on a Windows 7 64-bit, and now he uses Windows 8 64, and says he can use it..
when I launch it from the command line, I get the timer, but when it counts down, no sound plays, and no sound is shown in the options..
it works fine when launched just from the .exe file though..
it only supports WAV files.. the 1st method above can use any audio file..
Chris also said that there'll be a Whole New Version 2 of his Orzeszek Timer that'll be out in a couple months.. he said its only about one full days work, but he's got alot of other things going on right now.. he said he's planning on adding command line location parameters for the audio file, and other command-line buffs.. and i think support for more audio file types
so we should all definitely be looking forward to that
