Is there way to wire up a block of code to execute when a DNN module/extension is installed and/or upgraded?

 I'm looking for a method of programatically creating an Admin page within the DNN instance as part of my custom module, and have that page automatically get setup when the extension is installed. Also, a method of automatically removing that page when the module/extension is uninstalled would be nice too.

Thank you for any suggestions.

   As far as I know. DNN doesn't provide any method to let you execute your code after install (or uninstall). I recommend you try do it in your module instance. For example, when user put your module on a page first time, you can execute your code (to create page, or something else). Of course, you need to create something to indicate that it is the first run.

you can implement the IUpgradeable interface in your module and use that - see http://www.dnnsoftware.com/wiki/page/...

Are there any more recent articles and/or examples on implementing IUpgradable?

The Code Project article link at the link you posted is from 2009 and from a much older version of DNN.

Sure, there's load's in platform code (taxonomy, journal, htmleditorprovider, htmleditor etc.) - grab a source download from http://www.dnnsoftware.com/community/... 

Here's a simple example from DNN Platform\Modules\HTML\Components\HtmlTextController.cs

public class HtmlTextController : ModuleSearchBase, IPortable, IUpgradeable

...removed various content

        public string UpgradeModule(string Version)

        {

            switch (Version)

            {

                case "05.01.02":

                    //remove the Code SubDirectory

                    Config.RemoveCodeSubDirectory("HTML");

                    //Once the web.config entry is done we can safely remove the HTML folder

                    var arrPaths = new string[1];

                    arrPaths[0] = "App_Code\\HTML\\";

                    FileSystemUtils.DeleteFiles(arrPaths);

                    break;

                case "06.00.00":

                    DesktopModuleInfo desktopModule = DesktopModuleController.GetDesktopModuleByModuleName("DNN_HTML", Null.NullInteger);

                    desktopModule.Category = "Common";

                    DesktopModuleController.SaveDesktopModule(desktopModule, false, false);

                    break;

                case "06.02.00":

                    AddNotificationTypes();

                    break;

            }

           return string.Empty;

        }

If you look into DNN Platform\Modules\HTML\dnn_HTML.dnn you'll see the module definition businessControllerClass mode referencing the class above, and declaring that it supports Upgradeable i.e.

  <component type="Module">

          <desktopModule>

            <moduleName>DNN_HTML</moduleName>

            <foldername>HTML</foldername>

            <shareable>Supported</shareable>

            <businessControllerClass>DotNetNuke.Modules.Html.HtmlTextController, DotNetNuke.Modules.Html</businessControllerClass>

            <supportedFeatures>

              <supportedFeature type="Portable" />

              <supportedFeature type="Searchable" />

              <supportedFeature type="Upgradeable" />

            </supportedFeatures>

            <moduleDefinitions>
