I checked out some DILL articles. Nowhere is it explained whether a DILL can contain it's own resources. Can someone explain whether your DILL can contain Dialogs; and if so how can this be provided for linkage in a program.?

Since I don't know C#, or use the #include <windows.h> (because I use MFC exclusively), the articles you provided are useless to me. Thanks anyway.
