Delphi has the ability, like Visual Basic and C++, to incorporate off the shelf controls. I make full use of this capability to build the SETI Net user interface. I have checked out the list of components and as of this date and they are alive.

If you plan to build your own version of SETI net contact me and I will send you the complete source code. You will have to change the code as you go to customize it for your hardware. For example I'm almost sure you don't have a rotor controller like mine so the antenna.pas unit will not work or will require lots of changes for your system.
