Visual Studio problem

I have a problem with one of my projects in Microsoft Visual Studio.
I have made a SWF loader and I have it to where you can upload the SWF from your hard drive or from a URL.

My problem is that is there a code that I could put on a button to make the flash go full screen? this is the code I tried and it didnt work.

 Private Sub FS_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FS.Click
        flashob.AllowFullScreen = True
    End Sub

flashob is my flash object and FS is my button

the link to my Forums(which is were my program is) is in my sig, if you want to try it out, it’s Called “Flash Player Project”
