chinman has asked for the wisdom of the Perl Monks concerning the following question:

Does anyone know if and how Perl can be used as an OLE automation server, e.g. other client applications such as Excel can control a Perl executable. I see it is possible to use Perl as the client with Win32::OLE...but not as the server. Any help would be appreciated.

    Yes, you can build a COM/ActiveX server using ActiveState's PerlCtrl, in the Dev Kit. I have used this for turning Perl modules into COM objects that can be accessed from VB. It does a remarkably good job of converting the COM datatypes into Perl's scalars, hashes and lists.

    There are a few quirks, and I suggest starting with a hello, world and moving on in short steps. The only downside is that the DLL starts at around 1Mb for the simplest object.

      Yeah, it is great!

      The DLL size can be as small as 20k if you don't go for a freestanding DLL. You only need the freestanding DLL if perl isn't installed on the target computer.

    I have not tried this, but I've thought about using "script components" with PerlScript. Bascically, this will run your script as a server, and it works with any scripting language installed as an ActiveX Scripting Engine.

    Also, ActiveState sells something for that in their DevKit.
