Searching for specific attributes

Q: I was trying out the LMD RTF wrapper (using BCB 6) and wanted to know what would be the best way to search for words or characters with a specific attribute. A:

• Use FindTextEx

Simply add wininet.lib to your project (file can be found in \lib directory of your C++ Builder / BDS / CRS installation). In recent IDEs you can also add

NG Serialization

How to serialize collections

Serializing collections, including custom or standard collections (like TList) requires writing custom converters. For example, lets consider the folowing collection declaration:

type
  TItem = class
  public
    X: Integer;
    Y: Integer;
  end;

  TItems = class(TObjectList<TItem>);

To be able to serialize it, we need to declare a converter class, and associate this class with our collection using Converter attribute:

type  
  TItemsConverter = class(TConverter)
  public
    function  GetReadMode: TReadMode; override;
    procedure Write(S: TSerializer; const V); override;
    procedure Read(D: TDeserializer; var V); override;
  end;

  [Converter(TItemsConverter)]
  TItems = class(TObjectList<TItem>);

The converter can be implemented like this:
