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

// Download a URL into an in-memory MHT web archive contained
// in a string variable.
// The following URL is randomly picked and was valid at the time of writing this example:

// Extract the HTML and embedded objects:

ls_PartsSubdir = "objects"

// Extract to C:/AAWorkarea/mhtTesting/lodge.html.
// images and other embedded objects are placed in
// C:/AAWorkarea/mhtTesting/objects.  Directories are automatically
// created if they don't already exist.
