In Search of WinUnits >>>

Hi All,
          I'm just getting my head around the principles of BP7 and have
quite a few examples using various units regauarding windows i.e
WinCRT, WinTypes etc etc etc.   Any Idea where I could get a copy of these
units, or are they part of Delphi? I have a copy of Delphi but dont seem to
get on with it too well, so I'm hoping these units are for good old BP7 ..

   All replies most welcome

Cheers Martin
