Thank you Safiur
Can't get it to work though :(
All that happens is the page goes into busy mode (window disabled with 3
circles) and freezes :(

Debugging does not seem possible either, it just works or it freezes till i
figure out the error.

I have this added to lib.js...
    gettime: function(id, idx)
    {
      var elt = $_(id);
      $_(idx + ':entry').value = elt.currentTime;
    },

    settime: function(id, seconds)
    {
      var elt = $_(id);
      elt.currentTime = seconds;
    },

and i call it like this..

Public Sub WebButton1_Click()

WebForm1._AddJavascript("gw.sound.gettime(" & JS(WebAudio1.Name) & ", " &
JS(WebTextBox1.Name) & ")")

End

Public Sub WebButton2_Click()

WebForm1._AddJavascript("gw.sound.settime(" & JS(WebAudio1.Name) & ", 20)")

End

Neither work, just locks the window up :(
