* This requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* If SharePoint Windows classic authentication is used, then set the 
* Login, Password, LoginDomain, and NtlmAuth properties.
loHttp.Login = "SHAREPOINT_USERNAME"
loHttp.Password = "SHAREPOINT_PASSWORD"
loHttp.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
loHttp.NtlmAuth = 1

* 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.HttpRequest')
loReq = CreateObject('Chilkat.HttpRequest')
loReq.HttpVerb = "POST"
loReq.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
loReq.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST")

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

* Send the POST using https (TLS). Port 443 is the default port for https.
lnBUseTls = 1
loResp = loHttp.SynchronousRequest("SHAREPOINT_HTTPS_DOMAIN",443,lnBUseTls,loReq)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    CANCEL
ENDIF

* If failed, the response body contains XML 
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXml = CreateObject('Chilkat.Xml')
loXml.LoadXml(loResp.BodyStr)

IF (loResp.StatusCode <> 200) THEN
    ? "Response status code = " + STR(loResp.StatusCode)
    ? loXml.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>
    * 

    ? "Failed"
