SUMMARY
=======

This article demonstrates how to create a Visual Basic project that plays audio
files with the AU file extension. The project uses the DirectShow run-time file,
Quartz.dll, version 5.1.18.1024 or later. This DirectShow run-time file is
shipped with Internet Explorer 4.01 and Visual Studio 6.0.

MORE INFORMATION
================

This section assumes you are familiar with using objects and references in your
Visual Basic project and that you have a .AU file to use with the project. If
you are not familiar with using objects and references in your Visual Basic
project, see the REFERENCES section of this article.

Steps to Create the Project
---------------------------

1. Start a new Standard EXE project in Visual Basic. Form1 is created by
  default.

2. From the Project menu, select References, and add a reference to the
  DirectShow runtime file, quartz.dll. You may need to Browse for this file in
  your System directory. After you make a reference to this file, the
  ActiveMovie Control type library appears in the Available References list box
  of the References dialog box.

3. Add a CommandButton to Form1.

4. Paste the following code to the Code window of Form1. Change the String
  variable MyFile to the path and filename of your AU file:

  Option Explicit

  Private Sub Command1_Click()
     Static PMC As Object
     Dim MyFile As String

     MyFile = "<Path and Filename of the AU file>"
     Set PMC = New FilgraphManager
     PMC.RenderFile MyFile
     PMC.Run
  End Sub

5. On the Run menu, select Start, or press the F5 key to start the program.
  Click on Command1 and the AU file will start playing.
