How to apply the action to several Outlook items selected?

问题

The code here works for one item only. How to modify that to run DisplayItemMetadata (see the code) for each item selected?

Upd. tried to do the following:

For Each individualItem In Application.ActiveExplorer.Selection
    With objButton
        .BeginGroup = True
        .Caption = "My &item"
        .FaceId = 1000
        .Tag = "DisplayItemMetadata"
        If Not IsNull(Selection.Item(1)) Then
            On Error GoTo 0
            ' Just in case the item selected
            ' doesn't have a valid EntryID.
            ' .Parameter = Selection.Item(1).EntryID
            .Parameter = individualItem.EntryID
            On Error GoTo ErrRoutine
        End If
        .OnAction = _
            "Project1.ThisOutlookSession.DisplayItemMetadata"
    End With

Next individualItem

You need to iterate over the Selection object, as follows:

Dim individualItem As Object
For Each individualItem In Application.ActiveExplorer.Selection
    'Perform some action on individualItem
Next Message

If you have a function that performs an action on a single selected item, then you should change that function to take a parameter (the item to perform the action on) and then call that function inside the above loop.
