[RESOLVED] Making a progressbar's length equal to music length ?

[Link]

How can i make a progressbars length the same as the music's length ?
Like if the song is halfways the progressbar is halfways.

progress = progressbar1
player = axWindowsMediaPlayer

' Hardcoded maximum, because i know the length of the song...
Progress.Maximum = 269
' setting the value to the current time
Progress.Value = player.Ctlcontrols.currentPosition

But how do i loop it so it is synchronized with the song ?
