Create Own Track / Volume Sliders / Even A Custom 'screen' To Play Visualisations / Movies?

I've recently been working on a simple media player (following some guide and using my small brain ). I have created a simple playlist, with load/ save ability, add remove track and play and all the normal bull . However I was wondering if I could get some help making it more advanced: How do I create my own track / volume sliders - and even a custom 'screen' to play visualisations / movies? how do I create skip buttons (the ones on the media player controller don't work :@)? I know how to make a button skip a track (I think), but how to I make it skip to the next track in my playlist box? [code] I have created a context menu for my playlist, with buttons such as play, add and remove, but I want it so that when I right click on song the code activates on the song I right clicked on. At the minute whatever song I right click on it still runs the code on the song that selected not the one I right clicked on.Also my playlist, displays the whole file location of the tracks, how to I make it display only the tracks name.Also I have an open dialog control, I know how to set a filter, but how do i set it to filter more than one extension.please note that most of this code is from various guises, and I have simply edited it and merged different codes to suit my needs.
