Playing a music file with QuickTime

Question

I am new to QuickTime programming. I am using Quick Time Version 7.4.5 on Windows Vista. I am simply trying to play a music file as a movie, no video. It successfully creates the movie object and the control displays but no music is played. I am using QTOControl (COM libraries for use with .net) for Windows. Can anyone tell me what I am missing in the below code snippet?
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using QTOControlLib;
using QTOLibrary;
namespace WindowsApplication2
public partial class Form1 : Form
public Form1()
InitializeComponent();
private void Form1_Load(object sender, EventArgs e)
string errMsg = "";
try
axQTControl1.ErrorHandling = (int)QTErrorHandlingOptionsEnum.qtErrorHandlingRaiseException;
axQTControl1.URL = "C:\\path to music file.m4a";
axQTControl1.CreateNewMovie();
if (axQTControl1.Movie != null)
axQTControl1.Sizing = QTSizingModeEnum.qtMovieFitsControl;
axQTControl1.Movie.AutoPlay = true;
axQTControl1.MovieControllerVisible = true;
axQTControl1.Movie.Play(1.0);
catch (COMException ex)
// catch COM exceptions from QT control
errMsg = "Error Code: " + ex.ErrorCode.ToString("X") + "\n";
QTUtils qtu = new QTUtils();
errMsg += "QT Error code : " + qtu.QTErrorFromErrorCode(ex.ErrorCode).ToString();
catch (Exception ex)
// catch any exception
errMsg = ex.ToString();
if (errMsg != "")
string msg = "Unable to create movie:\n\n";
msg += errMsg;
MessageBox.Show(msg, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

Open the activity window while the MP3 plays. You will see it (Xbytes of Ybytes incrementing higher). Double click on it. Winds up in your downloads folder and you probably have to rename it.
You can often right click on embedded video and the save as source/as quicktime is there as well.
You can set preferences to open Quicktime in a player vs. embedded (which is what I do) and then you can saveas in the player window.
