I need to translate a program in others languages, actually I have the same program in 3 languages (english, spanish, portuguese), but I translated, recompiled, and I have 3 separate executables. And add more languages, and keep links, and adding new functions is driving me crazy.
So now I decided to keep a single executable, and a external language file, so adding new languages does not need recompiling, just editing the language file with a text editor, and everything is ok.
I want to keep all languages in a single external file. like international.lang
[portuguese]
greeting="Bem-vindo"
[spanish]
greeting="Ben venido"
if the file international.lang
is not there, or your language is not on the file, the program will launch in english by default, with no errors. Just like most multi-languages programas based on resources.
So the question is, how detect the Windows language in delphi? Any thoughts on my approach? There is any way to replace all captions on dialogs programaticly?
ps: I'm using delphi7, and I can't find any component that is free that is good.
You can use the GetSystemDefaultLCID
function to get the locale identifier and then use the VerLanguageName
function to resolve the language associated name. or use the GetLocaleInfo
function
Check this sample
{$APPTYPE CONSOLE}
uses
Windows,
SysUtils;
procedure Test_VerLanguageName;
var
wLang : LangID;
szLang: Array [0..254] of Char;
begin
wLang := GetSystemDefaultLCID;
VerLanguageName(wLang, szLang, SizeOf(szLang));
Writeln(szLang);
end;
procedure Test_GetLocaleInfo;
var
Buffer : PChar;
Size : integer;
begin
Size := GetLocaleInfo (LOCALE_USER_DEFAULT, LOCALE_SENGLANGUAGE, nil, 0);
GetMem(Buffer, Size);
try
GetLocaleInfo (LOCALE_USER_DEFAULT, LOCALE_SENGLANGUAGE, Buffer, Size);
Writeln(Buffer);
finally
FreeMem(Buffer);
end;
end;
begin
try
Test_VerLanguageName;
Test_GetLocaleInfo;
except
on E: Exception do
Writeln(E.ClassName, ': ', E.Message);
end;
Readln;
end.
Note : Starting with Windows Vista exists new functions to get the same locale information, check these functions GetLocaleInfoEx, GetUserDefaultLocaleName and GetSystemDefaultLocaleName
