The term for that is "load-time dynamic linking." The other term frequently used for that in the Delphi world is "static linking" (but it's not called that in the rest of the Windows world since the linking is not static at all). It's not Delphi that loads the packages. It's the operating system that loads them before any application code ever runs. Reynaldi, can you please confirm that this is what you're talking about? > Never tried to unload one, the idea is that they are global to the app > (otherwise why preload them?). Not sure how you could unload it, unless > you can find the handle Delphi got when it pre-loaded it. Delphi doesn't receive a handle. It's easy to get a handle to a loaded package, though. Use GetModuleHandle.

The prefix "pre" implies that the loading is happening before something else, but we've never been told what that "something else" is. -- Rob
