Subtract current track time from total track time
Hey all i have a song playing that displays the time like so:

0:00 / 4:47

The first time is the tracks current time. The second is the total track time of that song playing.

I split it like so:
Code:

`Dim tmpTimes As Array = lblSongTime.Text.Split("/")`
So tmpTimes(0) gives me 0:00 and tmpTimes(1) gives me 4:47.

Now i tried to subtract the tmpTimes(1) from tmpTimes(0)
Code:

`Debug.Print(CDbl(tmpTimes(1).replace(":", "") - tmpTimes(0).replace(":", "")))`
and i get: 447.. 446... 445... etc

What kind of calculation do i need in order to return a descending count?

Example: 4:47...4:46.....4:45...etc using the current time tmpTimes(0)?

Re: Subtract current track time from total track time
Solved:

Code:

```Dim times As String() = lblSongTime.Text.Split("/"c) Dim elapsedTime As TimeSpan = TimeSpan.ParseExact(times(0).Trim(), "m\:ss", Nothing) Dim totalTime As TimeSpan = TimeSpan.ParseExact(times(1).Trim(), "m\:ss", Nothing) Dim remainingTime As TimeSpan = totalTime - elapsedTime Debug.WriteLine(remainingTime.ToString("m\:ss"))```
