MediaPlayer Timers Help

[Nezoic]

Im writing a media player to be extended into another program at a later time. Currently Im working on the control functions and am having problems pausing the timer (which counts for a slide bar as well as elapsed time. Ive noticed SCiTE comes up with a TimerStop function but does this actually exist? If so where?

Ive also checked into a few DLL Functions and found a media timer MMTIMER on MSDN. Im not sure if something like this would be better to use or not. But Im sure the complication would increase quite a bit.

Any suggestions on how to pause this timer, or alternative timers would be a great help.

Here is the code along with two UDFs by Svennie and Simucal, respectively.

Anyone?

Well I found a sort of a work around by adding a global pause timestamp

Case $btnPause
            if $PlayingFile = 1 Then
                _MediaPause($Media)
                ;TimerPause($Timer)
                $PauseTime = $Pausetime + TimerDiff($timer)
                $resume_pause = 1
                AdlibDisable()
                $PlayingFile = 2 ;paused
            elseif $PlayingFile = 2 Then
                _MediaResume($Media)
                $Timer = TimerInit() ; reset init to zero to add pausetime and continue
                AdlibEnable("Timer", 50)
                $PlayingFile = 1
            EndIf

Seems to be fairly accurate however, I think I'll continue searching on the MediaPosition/MMTIME functions and see if i can work up something better.
