Data Abstract

I receive error during compile:
[BCC32 Error] NewLibrary_Intf.h(238): E2352 Cannot create instance of abstract class ‘TLoginService_Proxy’

this i the line 238:

TLoginService_Proxy* proxy = new TLoginService_Proxy(aMessage, aTransportChannel);

Hello,
Can you describe your project more detail?
What DA & Delphi version do you use? Can you provide your NewLibrary_Intf.h?
How did you install RO components?

Fwiw, TLoginService is abstract. You should be instantiating the proxy for your descendant login service?
