You are using IntToStr, a function which takes an int, a signed
number.  Automatic conversion between signed and unsigned integral
types is part of the language specification.  If the high bit is set
you then get a string representing a negative number, which is what
asked it to do.

There are several ways it could be done.
  AnsiString has a constructor which takes an unsigned long
  AnsiString's has a sprintf function
  Both sprintf and wsprintf will write to a character array that
    can then be assigned to an AnsiString
