' See Global Unlock Sample for sample code.

Dim mime As New Chilkat.Mime

Dim success As Boolean = mime.LoadMimeFile("qa_data/mime/sampleMime.txt")
If (success <> True) Then
    Debug.WriteLine(mime.LastErrorText)
    Exit Sub
End If


' Examine the structure in text format:
Dim txtStruct As String = mime.GetStructure("text")
Debug.WriteLine(txtStruct)

' The MIME structure as indented text is:
' multipart/alternative
'     text/plain
'     multipart/related
'         text/html
'         image/jpeg
' 

' Now examine the structure in XML format:
Dim xmlStruct As String = mime.GetStructure("xml")
Debug.WriteLine(xmlStruct)

' The MIME structure as XML is:
' <multipart-alternative>
'     <text-plain />
'     <multipart-related>
'         <text-html />
'         <image-jpeg />
'     </multipart-related>
' </multipart-alternative>
