Get the text body content of a MIME part.

Explains and demonstrates the GetBodyEncoded and GetBodyDecoded methods. This example uses the MIME test data located at http://www.chilkatsoft.com/testData/sampleMime1.txt

The sampleMime1.txt contains:

Content-Type: multipart/mixed;
 boundary="------------070404010201060604000708"

This is a multi-part message in MIME format.

Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8"

Download Chilkat MIME ActiveX

LOCAL loMime
LOCAL lnSuccess
LOCAL loPart1
LOCAL loPart2
LOCAL loPart3

loMime = CreateObject('Chilkat.Mime')

lnSuccess = loMime.UnlockComponent("Anything for 30-day trial.")
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    QUIT
ENDIF

*  Load the sampleMime1.txt file into the MIME object.
*  (This file is available at http://www.chilkatsoft.com/testData/sampleMime1.txt )

lnSuccess = loMime.LoadMimeFile("sampleMime1.txt")
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    QUIT
ENDIF

*  The sampleMime1.txt is a MIME document with a top-level
*  multipart/mixed containing 3 sub-parts, each of which has the
*  same body text but with different content-transfer-encodings and
*  using different character encodings (utf-8 and iso-8859-1).

*  Calling mime.GetBodyEncoded or mime.GetBodyDecoded on the
*  top-level multipart/mixed MIME object will return an empty string.
*  It is because the "body" of a multipart MIME object is always empty.
*  A multipart MIME object contains sub-parts (each a MIME object),
*  and it is only the leaf-objects that can have non-empty bodies.

*  Get GetBodyDecoded method returns the body text decoded
*  from whatever the content-transfer-encoding may be, and
*  converted from whatever charset encoding might be used.
*  In this case, calling GetBodyDecoded on each of the three
*  sub-parts will return the same string.
*  To demonstrate:

loPart1 = loMime.GetPart(0)
? loPart1.GetBodyDecoded()

loPart2 = loMime.GetPart(1)
? loPart2.GetBodyDecoded()

loPart3 = loMime.GetPart(2)
? loPart3.GetBodyDecoded()

*  The GetBodyEncoded method will NOT decode from
*  whatever content-transfer-encoding is used.  However, it will
*  convert from whatever internal character encoding
*  may be used to return a string appropriate for the calling
*  programming language (for example, in .NET or any language
*  using ActiveX, all strings are Unicode..)
