Title: Getting the locale ID an application was made for
Question: When making multiple language applications it can often be useful, in code, to know what locale the application was made for..
This can be done by reading the \VarFileInfo\Translation block of the files resource data.
Answer:
Here is a function for getting the base language an application was made for.
Make sure that "windows" is in your uses clause.
---
type TLANGANDCODEPAGE = record
wLanguage : word;
wCodePage : word;
end;
function GetDefaultLCID(filename : string) : LCID;
var InfoSize,puLen : DWord;
Pt,InfoPtr : Pointer;
LngBlk : TLANGANDCODEPAGE;
begin
result := $0400;
InfoSize := GetFileVersionInfoSize(PChar(filename),puLen);
if InfoSize 0 then begin
GetMem(Pt,InfoSize);
try
fillchar(LngBlk,sizeof(TLANGANDCODEPAGE),0);
GetFileVersionInfo(PChar(filename),0,InfoSize,Pt);
VerQueryValue(Pt,'\VarFileInfo\Translation',InfoPtr,puLen);
move(InfoPtr^,LngBlk,sizeof(TLANGANDCODEPAGE));
result := LngBlk.wLanguage;
finally
FreeMem(Pt);
end;
end;
end;

You can use the Languages object to get the name of the language..
Like:
---
procedure TForm1.Button1Click(Sender: TObject);
var lp0 : integer;
BaseLng : LCID;
begin
BaseLng := GetDefaultLCID(Application.ExeName);
for lp0 := 0 to Languages.count-1 do begin
if (Languages.LocaleID[lp0] = BaseLng) then begin
Label1.Caption := Languages.Name[lp0];
break;
end;
end;
end;
