Enabling a DLL to Run on DCOM

  • Article

The following steps outline how to enable a business object .dll to use both DCOM and Microsoft® Internet Information Services (HTTP) via Component Services.

  1. Create a new empty package in the Component Services MMC snap-in.

    You will use the Component Services MMC snap-in to create a package and add the DLL into this package. This makes the .dll accessible through DCOM, but it removes the accessibility through IIS. (If you check in the registry for the .dll, the Inproc key is now empty; setting the Activation attribute, explained later in this topic, adds a value in the Inproc key.)

  2. Install a business object into the package.

    -or-

    Import the RDSServer.DataFactory object into the package.

  3. Set the Activation attribute for the package to In the creator's process (Library application).

    To make the .dll accessible through DCOM and IIS on the same computer, you must set the component's Activation attribute in the Component Services MMC snap-in. After you set the attribute to In the creator's process, you will notice that an Inproc server key in the registry has been added that points to a Component Services surrogate .dll.
