How to display DirectSound Return Values in a Message Box

I have tried statements like:

Buffers.Add DSBuffer, strKey
MsgBox "Return code for Buffers.Add: " & Err.Description

However, these statements never return anything but a blank for Err.Description.

I would like to see values such as DS_OK, etc.

I am using DirectX8 and vb6.

Thank you in advance.
