Dim mht As New Chilkat.Mht

' This should be an absolute or relative path to the MHT file.
' It is the MHT to be unpacked.
Dim mhtPath As String = "qa_data/mht/test.mht"

Dim unpackDir As String = "C:/AAWorkarea/mht_unpack"
Dim htmlFilename As String = "test.html"

' Unpacking will create the HTML file C:/AAWorkarea/mht_unpack/test.html
' The image files are unpacked to C:/AAWorkarea/mht_unpack/images
' The unpackDir and partsSubDir are automatically created if needed.
