How to add a toolbar button & hotkey to empty the junk e-mail folder in Outlook 2003

I saw this discussion on Jonathan's blog, so here's one option:

#1: Follow the instructions in this article with this code:

Public Sub EmptyJunkEmailFolder()

    Dim outapp As Outlook.Application
Set outapp = CreateObject("outlook.application")
Dim olitem As Object
Dim fldJunk As Outlook.MAPIFolder

Set fldJunk = outapp.GetNamespace("MAPI").GetDefaultFolder(olFolderJunk)
For Each olitem In fldJunk.Items
olitem.Delete
Next

Set fldJunk = Nothing
Set olitem = Nothing
Set outapp = Nothing

End Sub

#2: Assign the above macro to a toolbar button as per the instructions in this article
#3: Change the icon for the macro as per the instructions in this article (stealing the icon from Tools | Empty Deleted Items for example)
