VB.NET

Save a Related Item to Disk

Demonstrates the Chilkat Email.SaveRelatedItem method, which saves the related item at a given zero-based index to a directory. If the directory or any of its components do not exist, Chilkat creates them. This example adds a related style sheet and saves it.

Background: Related items are the inline resources (images, style sheets) an HTML email carries in its multipart/related enclosure. SaveRelatedItem writes one of them out as a file — a building block for tasks like extracting a specific embedded image, or manually unpacking a message when you want finer control than the all-in-one UnpackHtml / AspUnpack methods provide.
