title: How do I update a website custom property in Sharepoint?
body: <p>I have some code which does the following:</p>
  
  <pre><code>const string KEY_CHK = "Microsoft.IW.PartCheck";
  SPWeb curWeb = SPContext.Current.Web;
  if (!curWeb.Properties.ContainsKey(KEY_CHK))
  { 
     curWeb.Properties.Add(KEY_CHK, "true");
     curWeb.Properties.Update();
  }
  </code></pre>
  
  <p>This runs as a webpart in a master page in Sharepoint 2007.</p>
  
  <p>I would like to be able to update the value of a property in a non-code way.<br>
  Through Sharepoint admin screens, or via Sharepoint designer.</p>
  
  <p>Is this possible? Where/how can I do it?</p>
