VCL Forms in COM+ Subscriber

[Ephraim]

D2006
I wishto split an application usimg COM+. <y understanfing is that yje
business logic will go inti the publishr which will trigger events to uodate
the UI. I thus need to create a VOM+ subscription which has at least one
form in it.

Mosy ecamoles show COM+ subscriptions usinf ShowMessage.
1) Can I desigb ab ActiveX library with a VCL Form in it?
2) Is this model correct i.e. COM+ for this splitting.
3) Should the UI be in an Automation Server and if so can I still use COM+
4) Is .Net a better approach

As these qustions must show I am inexperienced in COM+ and any decent
docs/tutorial other than ehat D007 offers woyld be appreciated.

TIA

Using COM means publishing the interface, etc. so that everything is
visible to the host application. This also means that other people will
also be able to use your hardwork. To prevent other from using it you
will have to implement some sort of Licensing system so that all the COM
objects/ActiveX that you create will not be callable by other software
except your own one.

You can desing an ActiveX with VCL forms in it.

I would advise you to use the Pluging architecture as described at
delphi.about.com
