Hi!

About the scrollbar I don't know.

About the soundwave, maybe you can use ShellExecute. This is a windows function that runs a file with the default application for its extension.

First you need to declare the function:

Public Declare Function ShellExecute Lib "shell32.dll" Alias _
           "ShellExecuteA" (ByVal hWnd As Long, ByVal lpOperation As String, _
           ByVal lpFile As String, ByVal lpParameters As String, _
           ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Then, you can invoke it from your click event:

Call ShellExecute(0, vbNullString, sFile, vbNullString, sFilePath, 1)

Both sFile and sFilePath are variables you'll need to initialize with you file and its path.

HTH,
