You will have to implement an enumerator for your TCountryAddressFormats class that returns TCountryAddressFormat references.
This isn't a language feature that "just works" - you have to put some infrastructure in place to support it. The feature appears to "just work" for a bunch of VCL types (TStringList etc) because the VCL already contains the necessary infrastructure additions (and which should provide the examplar implementations on which you could base your own). -----Original Message----- From: delphi-boun...@delphi.org.nz [mailto:delphi-boun...@delphi.org.nz] On Behalf Of Robert martin Sent: Thursday, 15 October 2009 10:06 a.m. To: NZ Borland Developers Group - Delphi List Subject: [DUG] Stupid /easy question Hi After the D2010 presentation yesterday I decided I should actually use some of the D2007 features I had not gotten around to using. Specifically the For .. in construct. I am sure I am missing something but here iss what I want to do I have the following 'old school code' (note the base class here inherits from TObjectList) procedure TCountryAddressFormats.LoadStringListWithCompanies(Strings: TStrings); var Counter : Integer; begin for Counter := 0 to Self.Count - 1 do begin Strings.AddObject( TCountryAddressFormat(Self.Items[Counter]).CountryName, Tobject(TCountryAddressFormat(Self.Items[Counter]).CountryRefAsInteger) ); end; end; I wanted to replace it with procedure TCountryAddressFormats.LoadStringListWithCompanies(Strings: TStrings); var CountryAddressFormat : TCountryAddressFormat; begin for CountryAddressFormat in Self do begin Strings.AddObject( CountryAddressFormat.CountryName, TObject(CountryAddressFormat.CountryRefAsInteger) ); end; end; but I get the following error [DCC Error] AddressFormat.pas(157): E2010 Incompatible types: 'TCountryAddressFormat' and 'Pointer' what am I missing ?
