DI API - Retrieve specific message object when you already have the code?

Question

The MessagesService object lets you retrieve a message using the message header. It also lets you retrieve a list of message headers from the inbox or sent mail.
Unfortunately, I don't see any way to create a single message header if I already know the code. The MessageHeaders collection has an Add method for a single MessageHeader but there does not appear to be a public constructor for the MessageHeader object.
Trying to create a new message header like
oMsgHeader = new MessageHeader();
or
oMsgHeader = new MessageHeaderClass();
both compile but cause a COM exception when actually executed.
So, other than retrieving all of the message headers and finding the message I want is there any way to retrieve a specific message when the key (Code) is known?

Dear William Faulk,
My previous reply is not accurate. The MessageHeader can initialized by Inbox our Outbox but can not to initialize a single message header individually by now.
So the code will as follows
For i = 0 To oUserInbox.Count - 1
    oMessageHeader = oUserInbox.Item(i)
    If oMessageHeader.Code = "myKey" Then
        oMessage = oMessageService.GetMessage(oMessageHeader)
    End If
Next
