Here is how you retrieve the text from an edittext item in a dialog.
Remember to do this _before_ you DisposDialog() the dialog.

First, define a helper routine
/* GetDIHandle - return handle value of dialog item
 */
Handle GetDIHandle(i)short i;{
  short theType;
  Handle theHandle;
  Rect theRect;

  GetDItem(thePort, i, &theType, &theHandle, &theRect);
  return theHandle;
}

Then, you can fetch it like this:
Str255	s;

SetPort(myDialog);
GetIText(GetDIHandle(ITEM), s);
