1. I have created an out of process COM Server(ciMultiInstance). No visual
behaviour
It works well & can interact between various clients. I was using a form to
do the initial development.
after that I remove the form, and started making it an NT Server

2. I want to make it a NT Service, so that it auto starts. I did this & the
NT service starts successfully
(configured as  Log On as System Account) The service starts successfully

3. I use a test application to create the COM object. Here another instance
of the exe starts
which dies(exits) after some time

AM I missing anything

TIA for any help

A COM/NT service also needs to have the LocalService subkey under the AppId.
You have to manually do that in D4. For info, go to my site and into the
downloads section: there's a simple sample there with readme instructions.

Hi,

Read my article about services with com server on my site
http://www.chat.ru/~aldyn/svcom_frame_art.html
This problem is much more complex then it seems.

Server(ciMultiInstance). No visual

My Server is not in the AppID section of the registry. The
DCOMHelloWorldService.Object1 comes. It is also not visible in the DCOMCNFG
tool.

Is there anything I need to do for this ? (My Server has two automation
objects in it.)

Manoj

I Got it working. Some snafu in the EXE (It was a ActiveX DLL project which
I changed by hand to program in the project source).
I created a new Service Application & added the com objects in this.
Everything worked.

Thanks a lot Binh

What is the criteria for an item appearing in the AppID RegKey, when a
Comserver is registered ?

Does Delphi (generated code i.e. applicaiotn) creates the entry, or is it
done be one of windows API calls ?

Manoj

The server is supposed to register its AppId. But DCOMCNFG is smart enough
to put one in for you if you don't have one - I think it picks the lowest
valued CLSID in your server and uses that as your server's AppId.

As of D4, the VCL source does not register the AppId. I believe D5 has a
function that puts in the LocalService key into the AppId.

Yes Binh, Thats the way it works. Thanks.

To accelerate the process
1. I create the APPID entries myself with the Class GUID (The lowest one), &
LocalService in my Service event AfterInstall usig TRegistry...
2. I then just run dcomcnfg & close it.

The above approach works & I feel shortens the admin work when I want to
deploy the components on the Production server.

As a precaution, I remove the APPID entry in the AfetUnInstall Event.
