Microsoft Access does not have a built-in function to play sound files onevents, such as when a form is opened or closed. However, you can use theMicrosoft Windows 3.1 application program interface (API) through AccessBasic code to create a user-defined function to play sound files.

This article assumes you are familiar with Access Basic and Windows APIs.In this article, the use of error trapping has been omitted to keep theinformation as clear and concise as possible.

Follow these steps to create a user-defined function to play sound files:
  1. Create a new module with a single function named PlaySound().

    NOTE: In the following sample code, an underscore (_) is used as a line-continuation character. Remove the underscore from the end of the line when re-creating this code in Access Basic.
        '*****************************************************************    'Declarations section of the module.    '*****************************************************************      Option Explicit      Declare Function sndplaysound% Lib "mmsystem" (ByVal filename$, _                                                     ByVal snd_async%)    '================================================================    ' The following function PlaySound calls the Windows API function    '================================================================      Function PlaySound (msound)         Dim XX%         XX% = sndplaysound(msound, 1)' play mmwave sound         If XX% = 0 Then MsgBox "The Sound Did Not Play!"      End Function						
  2. Save the module as Play It Sam.

    The following steps use a command button to trigger the sound, but you can use other events to trigger the sound.
  3. Add a command button to a form that you want to play the sound from:

          Object: Command Button      -------------------------------------------      Name: Push_Button_1      Caption: Play Chimes      On Click: =PlaySound("C:\WINDOWS\CHIMES.WAV")      (Where C:\WINDOWS\ is the location of the sound file and CHIMES.WAV      is the sound file.)						
NOTE: The Name property is called the ControlName property and the OnClickproperty is called the OnPush property in Microsoft Access 1.x.

When the form is open in Form view, you can play the sound by clicking thecommand button. You can assign this function to the form's OnOpen propertyif you want chimes to play when you open a form.

NOTE: This example does not have error trapping. Unexpected results mayoccur if the sound file is not in the location specified or does not exist.

If the sound (.WAV file) is in the table as an OLE field, the sound can beadded to the form out of the field list. You can then use a macro that doesa GoToControl [olefield], DoMenuItem form-edit-object- <verb>. You can runthis from a button on the form. It will go to the OLE field and edit theobject (the default edit is play for a sound).
