delphi...need help

[bekuzofu]

I've downloaded a delphi source from a site.
But when i open the source file it says class TNMUDP not found. What does this mean? does it mean i dont have the component? What do i do then?

I am also missing class TsimpleTCPClient. PLease help, thanks

The NM set of components was available with Delphi 5. They are not in Delphi 7 (not sure about 6) - you need to spend some time to convert the functionality to use the Indy components. This is not a straight forward conversion as the two component sets use different properties and methods.
