Hi again, Is it just me or is there a strange absence of online info with regards to developing standard uPNP media servers/renderers/control points. Sure there are white papers and specifications, but nothing you can grab and get quick answers. Where's all the on-line forums (this one is easy to find but is like a bone-yard)? I've used the Intel DeviceBuilder to create + export stacks based on servers and renderers running on my computer. Very nice..... But I have no idea as to how/when I should generate events and so-on within my code. For example, my renderer has been succesfully given a list of songs to play... My code can play the 1st song no problem, but when it finishes, I have no idea what events I should generate or how to tell the Control Point that the song is changing.... where's the use cases? I am so lost..... arrgh! Any pointers much appreciated.
