Yes you can get some information. It's more a question of how. You need to have your objects support IDispatch, then you can access the type lib information more easily - otherwise you would have to descend into C/C++ to read through the type library.
If you load the DLL, then call DllGetClassObject (or use the equivalent COM object call - get classFactory (I think that is the function call)) , passing in the class ID/GUID, you can get a reference to the class object factory. From there you can get the COM type info interface for the objects. Perhaps the easiest, would be to add another interface to your objects (or your factories) to supply the information you want. In either case look in the ActiveX and ComServ unit. If you have to you get class Id's etc from the registry (Yuk). Or you could add another method to your DLL to export the ComClassManager - which would make things very easy then (you could then use Delphi RTTI on the class factories and object instances).

If so how would I go about doing it? *Goes back to read "Delphi COM programming" hoping for a miracle* --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of "unsubscribe delphi" Web Archive at: http://www.mail-archive.com/delphi%40delphi.org.nz/ --------------------------------------------------------------------------- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of "unsubscribe delphi" Web Archive at: http://www.mail-archive.com/delphi%40delphi.org.nz/
