VBScript Requires Chilkat v11.0.0+

Extract Files from Binary SOAP MTOM MIME

See more MIME Examples

This example demonstrates how to extract files from a binary SOAP MTOM MIME document. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

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

set mime = CreateObject("Chilkat.Mime")

'  In this example, we have a MIME file containing 8bit (non-encoded) binary data,
'  and it is what I call "headless".  MIME is headless when it omits
'  the top-level header.  The file we have here begins with the first
'  boundary string.

'  The structure the MIME to be loaded is:

'  multipart/mixed (inferred because it is headless)
'      application/xop+xml
'      image/jpeg
'      image/gif
'      image/gif
'  

success = mime.LoadMimeFile("qa_data/mime/headless_binary_soap_mtom_mime.mim")
If (success = 0) Then
    outFile.WriteLine(mime.LastErrorText)
    WScript.Quit
End If
