Question

i started creating application only using dpr file in delphi 2009 , i think all basic things work i use system ,sysutils and more…. but now i want to use timer and some other non-visual components (some basic indy components to use internet) is there any ways to do this
i do not bother using units (but not forms)

Answer 1

You can put non-visual components on a Data Module.

I use that a lot because you still have the design-time benefits (properties and events in the object inspector, logical placement in your designer).
