Multilingual part strings (or: string to variable)

Posted on 2002-03-28

While trying to translate a project, I got the
following problem:

The message string s
  s:= 'The file ' + fname + ' does not exist';
contains two constant strings ('The file ' and
 'does not exist');

The simple way would be to define string ressources or constants, which will be translated separately,
with this result:
  s:= Ressource[currentlanguage,_THE_FILE] + fname +    Ressource[currentlanguage,_DOES_NOT_EXIST];

Now I'm looking for a more advanced way (and easier way for the translator) to solve the problem.

E.g. if one could write all parts together into text-files
(one for each language), and parse the language-dependend file, somehow like this:

 FILE_DOES_NOT_EXIST = "The file" + fname + " does not exist";

The constant strings could easily be parsed (e.g. into
a stringlist Parts) and put together.
The problem would be fname, which will be
read as a string, but would have to be converted
into a variable-name. So I would need conversion
from a string to the content of the corresponding
variable name.

s:= Parts[0] + GetVariableContent(Parts[1]) +

Is there any way to achieve this?

Thanks for help,

Use Format().

s:= Format('The file %s does not exist',[fname]);

Format does also accept multiple parameters and allows to change their order. Therefore this makes it ideal for such tasks.

No way to convert a string into a variable-name?

Not for common variables, only for components. But trust me, you don't need this and it will work perfectly using Format()! That's what Format() is made for.

I think the best thing to do when creating multiple language app is to use Delphi's native support.
It comes with a wizard that turns to be a best!

Create a new project and click Project >Languages >Add Language on the Delphi main menu!

Hope it helps!
