How do I check "Allow IIS intrinsic properties" in a COM+ application programmatically?

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 have no experience with this particular property, but it seems to be documented in MSDN.

Answer 2

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.
