Hi, how can I calculate the current position of the progress bar if I know the length of a music track or movie?

scale to 100%, position is at X% (very simple 12 year old math)

Specialize a type, not a var.

@Thaddy
Sometimes your advice is negated by the way you belittle the questioner. Suppose the questioner is a refugee who has had no formal education at primary or teenage level?
If you can't resist adding a snide comment to complete your advice I feel it would be better that you not offer any response.

@Thaddy,
I have to concur with @howardpc and, FYI, putting people down doesn't make you look good, on the contrary.
