(Visual FoxPro) 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";

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Mime')
loMime = CreateObject('Chilkat.Mime')

* 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
    RELEASE loMime
    CANCEL
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..)
? loPart1.GetBodyEncoded()
