Hi, I am developing application with different modules. I want to create library for each module and link to the application at runtime whenever necessary and detatch it when not used. Clearly saying, I want each NIB to be made a library so that all nib's will not be loaded initially. When ever user needs it, it must be loaded. I want to create something like DLL's in windows(C#). How can we achieve this? Regards, satyam.
