images in mime format message

How can I read the content-id of an image in a body message that is in mime format?

I can get the child/content type and sub-type i.e image/gif for instance plus the actual image content. I however need the CONTENT-ID for referencing purposes in displaying my final output.

Is there a method in the MIMEEntity class or anywhere else like getContentAsText() or getContentType() etc that can be used but to get the content-id instead?

Thx

Use NotesMIMEEntity.ContentAsText property and then search the string returned by this property for content-id. For example, I use the following subroutine to concatenate all the header parts into a string called HeadersTextStr and all the content parts into a string called BodyTextStr:

(Declarations)
Dim HeadersTextStr As String
Dim BodyTextStr As String

Sub Concatenate

Dim mime As NotesMIMEEntity
Dim mime2 As NotesMIMEEntity

s.ConvertMime = False
HeadersTextStr = ""
BodyTextStr = ""
Set item = doc.GetFirstItem("Body")
If Not (item.Type = MIME_PART) Then
Exit Sub
End If
Set mime = item.GetMimeEntity

While Not (mime Is Nothing)
If Lcase$(mime.ContentType) = "text" Then
HeadersTextStr = HeadersTextStr & mime.Headers
BodyTextStr = BodyTextStr & mime.ContentAsText
End If
Set mime2 = mime.GetFirstChildEntity
If mime2 Is Nothing Then
Set mime2 = mime.GetNextSibling
End If
If mime2 Is Nothing Then
Set mime2 = mime.GetParentEntity
If Not (mime2 Is Nothing) Then
Set mime2 = mime2.GetNextSibling
End If
End If
Set mime = mime2
Wend

End Sub

I can then search the HeadersTextStr and BodyTextStr for whatever substrings I want:

Sub CheckMimeBody
If Instr(1,BodyTextStr,"content-id",5) Then
'Do some processing here
End If
End Sub

Hope this helps.

Thanks Scott worked fine however I realized that I left the setting part as well. I can't seem to then set the content-ID value of the new document I am creating. I tried setContentFromText(stream...) function but obviously this it is not recognised as a header setting.Part of my code is:

Stream stream = session.createStream();
MIMEEntity body = doc.createMIMEEEntity();
MIMEHeader header = body.createHeader("Content-Type");
header.setHeaderVal("multipart/mixed");
....
MIMEEntity child = body.createChildEntity();
stream.writeText(THE CONTENT-ID VALUE);
child.setContentFromText(stream,"image/gif",MIMEEntity.ENC_BASE64);

Obviously this isn't setting the header values coz when I read the headers of the new document it's returning:

Content-Transfer-Encoding: base64
Content-Type: image/gif

So I am still missing the content-id value in the header. How can i set this value maybe with something like setHeaderVal or what?

Thanks so much for the 1st pointer Scott.

I see ur point but it's getting a bit hectic. stream is just a way of passing any content to the entities I suppose nothing much to it. the real question is can I set the child entity's header value - Content-ID? As u can see that the funciton setContentFromText(...) does set the Content-Type (2nd parameter); and encoding (3rd parameter); All I need is to then set as well the Content-ID.

Will see if I can fit the socket idea in my situation.

NB: code above in java but nothing different or unique to lotuscript.
