' See Global Unlock Sample for sample code.

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


' This example will delete the folder /Documents/ChilkatTest2

Dim req As New Chilkat.HttpRequest
req.HttpVerb = "POST"
' If your Sharepoint site is within a site collection, then use "/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents/ChilkatTest2')" where "teamA" is the name of the site.
req.Path = "/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest2')"

' We need to add a form digest value in the X-RequestDigest header field.
' See this example for details on
' how to get (and cache) a form digest value
req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST")

' Add additional required headers.
req.AddHeader("IF-MATCH","*")
req.AddHeader("X-HTTP-Method","DELETE")

' Send the POST using https (TLS). (Port 443 is the default port for https.)
Dim bUseTls As Boolean = True

' If failed, the response body contains XML 
Dim xml As New Chilkat.Xml
xml.LoadXml(resp.BodyStr)

' Note: It seems that if an attempt is made to delete a folder that does not exist,
' the response status code is 200, indicating success.
If (resp.StatusCode <> 200) Then
    Debug.WriteLine("Response status code = " & resp.StatusCode)
    Debug.WriteLine(xml.GetXml())

' If successful, the response body is empty.
