playing a video after another one has ended with shockwaveflash player in c#

Question

I have a code that takes should take video urls from queue and play next video on the queue after 1 has ended. I just can't get the program to know if the video has ended or not. How can I do this?

This is what I got:

{
    if (songrequests.Count > 0)
    {
        var url = songrequests.Dequeue();
        axShockwaveFlash1.Movie = url;
    }
}
