Question

Component Services -> Computers -> My Computer -> COM+ Applications

Open a COM+ Application object.

Open Components.

Right-click on a class and select Properties.

Under ‘Advanced’ there is a check box for ‘Allow IIS intrinsic properties’.

How do I check this check box programmatically?

I can create and delete COM+ Applications programmatically, but the ComApplication class doesn’t seem to have ways to change settings in the created application.

Answer 1

I found out how to do it.

Apparently I have to get a collection of COM+ applications, find the one I want (by name), then get a collection of components in the application, then go through the collection and set the attribute:

            //get collection of applications         COMAdminCatalog catalog = new COMAdminCatalog();          catalog.Connect('127.0.0.1');          COMAdminCatalogCollection applications = (COMAdminCatalogCollection)catalog.GetCollection('Applications');          applications.Populate(); //no idea why that is necessary, seems to be          // appId for the application we are looking for         object appId = new object();          int count = applications.Count;         ICatalogObject item;          if (count == 0) return;          //search collection for item with name we are looking for         for (int i = 0; i < count; i++)         {              item = (ICatalogObject)applications.get_Item(i);              if (applicationName == (string)item.get_Value('Name'))             {                  appId = item.Key;                  Console.WriteLine('appId found for ' + applicationName + ': ' + appId.ToString());              }          }          // get all components for the application         COMAdminCatalogCollection components;          components = (COMAdminCatalogCollection)applications.GetCollection('Components', appId);         components.Populate(); // again, no idea why this is necessary          // set the attribute in all components          foreach (COMAdminCatalogObject component in components)         {              Console.WriteLine('Setting IISIntrinsics attribute in ' + component.Name + '.');             component.set_Value('IISIntrinsics', true);             components.SaveChanges();          } 

I think this can be done better and with fewer castings. But I don’t know how.

This will do.
