#  The intent of this example is to modify Content-Disposition
#  header fields from this:
# 
#  Content-Disposition: attachment; filename="a4 manuscript.pdf"; size=0;
#  	creation-date="Thu, 12 Apr 2007 06:39:10 GMT";
#  	modification-date="Thu, 12 Apr 2007 06:39:10 GMT"
# 
#  to this:
# 
#  content-disposition: attachment;
#  	 filename="a4 manuscript.pdf"
# 

mime = chilkat.CkMime()

success = mime.UnlockComponent("Anything for 30-day trial")
if (success == False):
    print "Failed to unlock"
    sys.exit()

success = mime.LoadMimeFile("testMime.txt")
if (success == False):
    print mime.lastErrorText()
    sys.exit()

#  This example assumes the header fields to be modified
#  are located directly beneath the top-level MIME part.

numParts = mime.get_NumParts()

for i in range(0,numParts):
    mimePart = mime.GetPart(i)

    disposition = mimePart.disposition()
    if (disposition == "attachment"):
        filename = mimePart.filename()
        #  AddHeaderField replaces the existing field if it already exists.
        #  Discard the contents of the existing Content-Disposition
        #  and replace it with "attachment".
        mimePart.AddHeaderField("content-disposition","attachment")

        #  Now add the filename attribute:
        mimePart.put_Filename(filename)

success = mime.SaveMime("modifiedMime.txt")
