I'm working on a simple localization effort in D2010. I'm handling all strings on forms because ETM seems like overkill for my needs, as did other 3rd party tools... (although I'm not so sure at this point!)

Is the code below for changing the Const.pas strings considered safe to change the button labels on standard message boxes?

procedure HookResourceString(rs: PResStringRec; newStr: PChar);
var
  oldprotect: DWORD;
begin
  VirtualProtect(rs, SizeOf(rs^), PAGE_EXECUTE_READWRITE, @oldProtect);
  rs^.Identifier := Integer(newStr);
  VirtualProtect(rs, SizeOf(rs^), oldProtect, @oldProtect);
end;

const
  NewOK: PChar = 'New Ok';
  NewCancel: PChar = 'New Cancel';

Procedure TForm.FormCreate;
begin
  HookResourceString(@SMsgDlgOK, NewOK);
  HookResourceString(@SMsgDlgCancel, NewCancel);     
end;
