VBA to play wav file

I am trying to in Excel 2000 using vb 6 on event for a command button play a wav file. I have tried two different codes that were on the net. My problem is this....they use declaration statments and i keep getting a debug error message saying that you cannot use declaration statements. Below is the most current attempt but it still debugs at the public static statement. Any suggestions or is there a better code or way to do this?

Thank you in advance.


using System;
using System.Runtime.InteropServices;
using System.Resources;
using System.IO;
namespace Win32
{
public class Winmm
{
public const UInt32 SND_ASYNC = 1;
public const UInt32 SND_MEMORY = 4;
// these 2 overloads we dont need ...
// [DllImport("Winmm.dll")]
// public static extern bool PlaySound(IntPtr rsc, IntPtr hMod, UInt32 dwFlags);
// [DllImport("Winmm.dll")]
// public static extern bool PlaySound(string Sound, IntPtr hMod, UInt32 dwFlags);
// this is the overload we want to play embedded resource...
[DllImport("Winmm.dll")]
public static extern bool PlaySound(byte[] data, IntPtr hMod, UInt32 dwFlags);
public Winmm()
{
}
public static void PlayWavResource(string wav)
{
// get the namespace
string strNameSpace=
System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();
// get the resource into a stream
Stream str =
System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream( strNameSpace +"."+ wav );
if ( str == null )
return;
// bring stream into a byte array
byte[] bStr = new Byte[str.Length];
str.Read(bStr, 0, (int)str.Length);
// play the resource
PlaySound(bStr, IntPtr.Zero, SND_ASYNC | SND_MEMORY);
}
}
}
