How to get access to an object between dynamically loaded packages?

Question

I need to know the user name and other data of the logged-in user in a project organized using BPLs. That is, how and where do I need to declare the user object and its creation, and how to get access to that object when a package is loaded at runtime? I don't have enough experience working with packages.

Answer 1

In a regular app, for the programmer there is no difference between using runtime packages or all in a single exe You can change the project to go with runtime packages or not, and your code won't change at all

That changes when you make a modular app that loads BPL modules on demand, chosing at runtime if a given module will be load, and doing it dynamically (ex. app made with a plugin-architecture in mind), then you need to design your own strategy to handle that

Myself, I work in that second way, and I do have some main modules wich give services to the "plugins", so when they are loaded, they do register themselves with the system: user control, navigation, whatever

Answer 2

There is nothing special to use objects in a package. You just add the unit name where the object is defined to the uses clause of the unit where the object is to be used.

You should really read the documentation on this topic. The you may ask more questions to clarify things you don't understand.
