Syntax

C++/CLI

Java

Python

public WebClient WebClient { get; set; }

public:  
   property System::Net::WebClient^ WebClient 
   { 
      System::Net::WebClient^ get() 
      void set(System::Net::WebClient^ value) 
   }

public void setURIConnecter(IURIConnecter value)

WebClient # get and set (LoadDocumentOptions)

Property Value

The .NET System.Net.WebClient object to use when downloading or uploading data from a remote URL. Default value is null.

Remarks

LEADTOOLS uses a System.Net.WebClient object when downloading or uploading data from a remote URL. This object contain many options for handling the credentials and proxy settings. If this value is null, LEADTOOLS will create a new System.Net.WebClient object with default options, use it for the operation and then disposes it.

If the operation requires custom settings for the credentials and proxy, or to subscribe to the System.Net.WebClient events for debugging and logging purposes, then the user can create their own object and set it in this property. LEADTOOLS will then use this instance instead of creating a new one. In this mode, the user is responsible for disposing the object when it is no longer used.

   options.FirstPageNumber = 1; 
   options.LastPageNumber = -1; 
   options.Password = null; 
   options.WebClient = null; 
   options.CachePolicy = new CacheItemPolicy(); 
   using (var document = DocumentFactory.LoadFromFile(Path.Combine(LEAD_VARS.ImagesDir, "Leadtools.pdf"), options))
