' The following comments apply to SharePoint Windows classic authentication.
' -------------------------------------------------------------------------
' For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
' The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
' The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
' Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
' for example, "chilkat" instead of "chilkat@mycompany.com"

Dim http As New Chilkat.Http

' If SharePoint Windows classic authentication is used, then set the 
' Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME"
http.Password = "SHAREPOINT_PASSWORD"
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
http.NtlmAuth = True

' -------------------------------------------------------------------------
' The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
' If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
' establish the cookie as shown at SharePoint Online Authentication
' -------------------------------------------------------------------------

' Indicate that we want an XML reply
http.Accept = "application/atom+xml"

' The contents of a SharePoint list can be downloaded by it's URI,
' which has the following URL format:
' https://xyzoffice.mycompany.com/_api/Web/Lists(guid'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx')/items

' To get the URI's for all SharePoint lists, 
' See Get SharePoint Lists.

' The output of this program (when I ran w/ my test SharePoint data) looks something like this:

' I found that not every item has a Title,  but as viewed in a browser, I can see each of the item's name.
' (The number of items agrees with what I can interactively see in a browser.) The mystery of what
' is being shown for the name (or title) in the browser will be investigated further as Chilkat
