'  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 file named "penguins2.jpg"
'  which is located in the "/Documents" folder.

Dim req As New Chilkat.HttpRequest
req.HttpVerb = "POST"
req.Path = "/_api/web/GetFileByServerRelativeUrl('/Documents/penguins2.jpg')"

'  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
Dim resp As Chilkat.HttpResponse = Await http.SynchronousRequestAsync("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req)
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


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

If (resp.StatusCode <> 200) Then
    Debug.WriteLine("Response status code = " & resp.StatusCode)
    Debug.WriteLine(xml.GetXml())

    '  For example, if the file did not exist, this would be the XML response:
    '  <?xml version="1.0" encoding="utf-8" ?>
    '  <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    '      <m:code>-2146232832, Microsoft.SharePoint.SPException</m:code>
    '      <m:message xml:lang="en-US">The file /Documents/penguins2.jpg does not exist.</m:message>
    '  </m:error>
    ' 

    Debug.WriteLine("Failed")

'  If successful, the response body is empty.
