Hi Andre, I’ve been working a little bit on the pending issues and will send you my codeunit with the most important functions that were missing: - read/write mp3 tag - read/write m3u playlist file I have been looking around for some CD player ocx but have not been succesful, VB examples use “winmm.dll”, but I have no been able to use it within Navision, I have found other CD player OCX but so far no time to work on it… On the other hand, I am also thinking of posting my complete mp3 player objects but I am still missing the testing phase … [xx(] Saludos Nils
