This Demo shows how to use embedded and external language resources.

You can comment or uncomment defs in Unit1.pas to change type of language resources.
There are three options:

1.
{$DEFINE EMBEDDED_LANGUAGE_RESOURCES} 
{$DEFINE EMBEDDED_LANGUAGE_RESOURCES_ALL}

All resources are linked to the exe file on compilation time. 
See list of resources in EhLibEmbeddedLangConsts.pas file.

2.
{$DEFINE EMBEDDED_LANGUAGE_RESOURCES}
//{$DEFINE EMBEDDED_LANGUAGE_RESOURCES_ALL}

Only selected resources are linked to the exe file on compilation time.

3. 
//{$DEFINE EMBEDDED_LANGUAGE_RESOURCES}
