*  The Content-Disposition header field provides a suggestion to the receiver for how the content is to be processed.
*  The standard dispositions are "inline" and "attachment".  

*  A disposition of "attachment" indicates the content is something to be saved to a file and not processed (such as rendering for viewing inline).
*  A disposition of "inline" indicates the content should be processed (displayed) inline with the other parts of the MIME message.

*  For example, an email client could handle a JPG image based on the disposition.  If the disposition is "attachment",
*  the email client (such as Thunderbird, GMail, or Outlook) might simply list the JPG image as one of the email's attachments,
*  but won't display the JPG image.  If the disposition is "inline", the email client might display the JPG image, but not list
*  it as an attachment.

*  The Content-Disposition header field can also include a "filename" attribute.  This is the suggested default filename if the content
*  is to be saved to a file.

loMime = CreateObject('Chilkat.Mime')

*  The Content-Disposition header field can be set or modified in two ways.
*  1) By setting the Disposition and Filename properties.

*  2) By setting the entire contents of the Content-Disposition header with the SetHeaderField method.
*     Setting the Content-Disposition header automatically updates the Disposition and Filename properties.

*  For example:
loMime.Disposition = "attachment"
loMime.Filename = "ghost.jpg"

*  The Content-Disposition header field contains this:
*      Content-Disposition: attachment; filename="ghost.jpg"
? loMime.GetEntireHead()
? "-"

*  If we set the entire header field..
loMime.SetHeaderField("Content-Disposition",'attachment; filename="zombie.jpg"')
*  The Content-Disposition header field now contains this:
*      Content-Disposition: attachment; filename="zombie.jpg"
? loMime.GetEntireHead()
? "-"

*  Notice how the Filename property has been updated
? "Filename property: " + loMime.Filename
? "-"

*  To change a particular attribute value, set the property.
loMime.Filename = "skeleton.jpg"
? loMime.GetEntireHead()
? "-"

*  To remove the filename from the Content-Disposition header,
*  set the property to an empty string.
loMime.Filename = ""
? loMime.GetEntireHead()
? "-"
