ContentID Property

Value of "Content-ID" header of the attachment (usually it is non-empty for embedded images and other documents related in the message body as CIDs). Such documents are called inline objects (and their IsInline property is set to True).

Note: ContentID property is often enclosed in "<>" symbols. To get the pure value of Content-ID, use PureContentID property instead.

Value Type:	String

Parameters:	None

Remarks:	This property is read-only

Usage example:

Dim Mailer, Msg, Attach
'Using visual basic to create object
Set Mailer = CreateObject("MailBee.POP3")
'Using ASP to create object
'Set Mailer = Server.CreateObject("MailBee.POP3")
'In ASP use Response.Write instead of MsgBox
Mailer.LicenseKey = "put your license key here"
Mailer.Connect "mailserver.com", 110, "MyName", "MyPassword"
If Mailer.Connected Then
  If Mailer.MessageCount > 0 Then
    Set Msg = Mailer.RetrieveSingleMessage(1)
    If Not Msg Is Nothing Then
      For Each Attach In Msg.Attachments
        MsgBox "ContentID: " & Attach.ContentID
      Next
    End If
  End If
  Mailer.Disconnect
End If
