What is the problem you are having with your code?

One thing, I believe if you want it to auto play when the selected item changes, you need to set the auto postback property on the listbox control to true.
ex: <asp:ListBox ID="ListBox1" runat="server" AutoPostBack="True">

Sorry, i assumed you were using asp.net for some reason.

I put together a quick windows form application with the windows media conrol and a listbox containing a list of media files.

When the listbox selected item is changed, this works for me to play the selected item in the listbox.

VB

Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ListBox1.SelectedIndexChanged
        AxWindowsMediaPlayer1.URL = ListBox1.SelectedItem
        AxWindowsMediaPlayer1.Ctlcontrols.play()
    End Sub

sir. i already done this but in the AxWindowsMediaPlayer1_PlayStateChange event, the code will not execute properly. any other idea?

Sorry, i am out of ideas for you. Based on what you posted is your code, the selected index changed event is empty. You have the code to play the movie on button1 click, which i dont understand what you are doing there. I would say the code is good, maybe the problem is the which events you have it in. Good luck!
