Hello, I'm writing a custom usercontrol for Umbraco. I need to access to page content. When I try something like: Code:Dim myPage As New umbraco.presentation.nodeFactory.Node(pageId) I get a NullReferenceException error [System.NullReferenceException - Object reference not set to an instance of an object.] The same happens also writing something like this: Code:Dim myPage As New umbraco.presentation.nodeFactory.Node() Any idea? Thanks to all. Lorenzo.

I have no problem with the first code line. So Do you test this running in umbraco? If not this will be your problem. The functions are only availible running in the scope of an umbraco installation. Cheers, Thomas

Thanks for your reply. I simply created a new solution referencing cms, businesslogic and umbraco dlls and created the usercontrol. Web.config replicate exactly the production environment. Importing the resulting dll into umbraco and putting my control in the usercontrols directory, gives the same result. I developed other usercontrols but usually I simply integrate my existing businesslogic into umbraco. This is the first time I need to get umbraco contents. What I'm doing wrong? Thanks. Lorenzo.

Ok I don't know your configuration. So I did my own usercontrol to get all informations via umbraco.presentation. Something like that: Code:
Dim n As new umbraco.presentation.nodeFactory.Node(nodeID)
Me.lblMessage.Text = "Nodename: " + n.Name
For Each p As umbraco.presentation.nodeFactory.Property In n.Properties
Me.lblMessage.Text += "<br/>Property '" + p.Alias + "': " + p.Value
next
You can get the dll and the ascx here: http://www.diehoehlers.de/media/432/getnode.zipThe complete project here: http://www.diehoehlers.de/media/429/th.zipTry this. If this doesn't work it must something other. Then you can get a complete information via adding ?umbDebugShowTrace=true to the end of your URL. hth, Thomas

Thank you for your help. I putted your usercontrol in usercontrols directory. I putted your dll in bin directory. I created the macro 'test'. I putted the macro on a page. Now I'm getting the following error: Code:renderMacro Rendering started (macro: Test, type: 3, cacheRate: 0) 0.010988 0.000033
umbracoMacro Usercontrol added (UserControls/GetNode.ascx) 0.011034 0.000046

The dll is made with .net 2.0. Are you using .Net 1.1? Thomas

Yes, I use Framework 1.1. I have installed your dll as you send me on Umbraco 2.1.4 which is compiled under .NET 1.1.
