getting playtime in minutes/seconds for sound file in windows media player?

[Mad Scientist Jr]

i'm programming windows media player (using cfcom for pocket pc,
vb.net) and
while i can read the duration and current position in the file

Private mediaPlayer1 As Odyssey.WMPCE.MediaPlayer
Text1.text = mediaPlayer1.CurrentPosition.ToString
Text2.text = mediaPlayer1.Duration.ToString

the both of these are of type Double. How can I convert these to
minutes/seconds?

Or does someone have code to read a mp3 / wav / windows media file
header and get the length in minutes/seconds, and then I can convert
with that as a basis?

Also WMP only seems to be seeing Windows media format files when I
open them:

If openFileDialog.ShowDialog() = DialogResult.OK Then
mediaPlayer1.FileName = openFileDialog.FileName

How can I get it to play mp3 and WAV files?

thanks

i ended up using this mp3 header object to get the time in seconds,
and then it was merely a matter of conversion to get the elapsed time:
