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

Ephraim

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
