title: Where should I put my utility methods? How can I used my customized form? (Delphi)
body: <p>I've been using Delphi for a little over a month, but I still do not know the proper way of doing things.</p>
  
  <p>If I have methods which I can use on a lot of projects should I put them on a Unit, Form or DataModule?
  I have not used a unit (in itself), New-> Unit. Should I put my utility methods there? If so, is there an example I can look at, a tutorial or whatever.
  I've used DataModules in the past, though it gives me the impression that it should only be used when I'm dealing with databases and such.</p>
  
  <p>Another thing, I'm customizing some forms (for instance a form with some TEdits that do specific things). 
  To use this, first I add this to the uses in the .dpr<br>
  <code>CustomizedForm in '\CForm\CustomizedForm.pas' ;</code><br>
  then I add <code>CustomizedForm</code> to the uses in my mainform (where I'll be using it).<br>
  Is this the correct way to do it? I'm was just guessing, it seems to work though I'm not particularly confident that it's the proper way.</p>
