email - Outlook 2010 VBA save attachments for certain date

I am trying to modify a macro to save all attachemnts from emails that arrived today. The problem is that I do not know how to reference the date property of an email object in Outlook VBA.

How can I do this and more importantly how can I find out how to reference objects on my own next time? I am not finding much reference material for the outlook object model.

my existing code is below:

Sub GetAllAttachments() 'Exports and saves all attachements in the inbox


Dim ns As NameSpace
Dim Inbox As MAPIFolder
Dim Item As Object
Dim Atmt As Attachment
Dim FileName As String
Dim i As Integer

Today = Format(Now(), "yyyy MM dd")

Set ns = GetNamespace("MAPI")

Set Inbox = ns.Folders("Secondary")
Set Inbox = Inbox.Folders("Inbox")

i = 0

If Inbox.Items.Count = 0 Then
   MsgBox "There are no messages in the Inbox.", vbInformation, _
          "Nothing Found"
   Exit Sub
End If


For Each Item In Inbox.Items
    If EMAIL_DATE = Today Then
        For Each Atmt In Item.Attachments
                   FileName = "C:\Email Attachments\" & Atmt.FileName
                   Atmt.SaveAsFile FileName
                   i = i + 1
        End If
    Next Atmt
Next Item


End Sub
