hmmmm, not sure what you're after. if your looking to call vlc istelf and pass the playlist, this is a simple shellexecute using the windows api, look at my answer in this post. It has a very nice sample in doing just that.
I think just click on the options button of the playlist not so sure name but quite sure that was a 2nd last tab click on the tab there opio0n avaialable of playlist, click and past songs there which you want to play.
.CtlVisible = True
' Loop until user presses Cancel button and
' add files to the playlist. The code _does not_ check the type of the file!
Do Until OpenFileDialog1.ShowDialog() <> Windows.Forms.DialogResult.OK
.Toolbar = True
(Sorry about missing syntax coloring. I still haven't found how to do it!!!)
(Never mind :) It seems to come by itself...)
