; Every part in a MIME messsage should include a Content-Type header field.
; The Content-Type indicates the type of content contained in the MIME part.
; For example: text/plain, image/jpeg, application/pdf, application/json, multipart/mixed, etc.

; Multipart content types are those where the MIME part's body is composed of N inner MIME messages,
; separated by a boundary string.
; This is how MIME gets a nested, tree-like structure.  The most common multipart MIME types
; are (for email related MIME) multipart/mixed, multipart/alternative, and multipart/related,
; and for HTTP related MIME, it is multipart/form-data.

; The Content-Type header field can be set or modified in two ways.
; 1) By setting the ContentType, Micalg, Name, Charset, Boundary, or Protocol properties.
;    Setting the ContentType property sets the primary value (such as "text/plain") of the header field.
;    Each of the other properties listed above will replace or add a particular attribute value.

; 2) By setting the entire contents of the ContentType header with the SetHeaderField method.
;    This updates each of the Content-Type related properties.

; For example:
$oMime.ContentType = "text/plain"
$oMime.Charset = "utf-8"

; The Content-Type header field contains this:
;     Content-Type: text/plain; charset=utf-8
ConsoleWrite($oMime.GetEntireHead() & @CRLF)
ConsoleWrite("-" & @CRLF)

$oMime.SetHeaderField("Content-Type","image/jpeg; name=""kitty.jpg""")
; The Content-Type header field now contains this:
;     Content-Type: image/jpeg; name="kitty.jpg"
ConsoleWrite($oMime.GetEntireHead() & @CRLF)
ConsoleWrite("-" & @CRLF)

; Notice how the properties have been updated:
ConsoleWrite("ContentType property: " & $oMime.ContentType & @CRLF)
ConsoleWrite("Charset property: " & $oMime.Charset & @CRLF)
ConsoleWrite("Name property: " & $oMime.Name & @CRLF)
ConsoleWrite("-" & @CRLF)

; To change a particular attribute value, set the property.
$oMime.Name = "doggy.jpg"
ConsoleWrite($oMime.GetEntireHead() & @CRLF)
ConsoleWrite("-" & @CRLF)

; To remove an attribute value from the Content-Type header,
; set the property to an empty string.
$oMime.Name = ""
ConsoleWrite($oMime.GetEntireHead() & @CRLF)
ConsoleWrite("-" & @CRLF)
