Hi *,
consider following sample program:

var
  b: array[0..255] of char; 
begin
  if getlocaleinfoa(LOCALE_USER_DEFAULT, LOCALE_SSHORTDATE, b, 
sizeof(b)) > 0 then
      writeln('LOCALE_USER_DEFAULT:',b);
  if getlocaleinfoa(LOCALE_SYSTEM_DEFAULT, LOCALE_SSHORTDATE, b, 
sizeof(b)) > 0 then
      writeln('LOCALE_SYSTEM_DEFAULT:',b);
  if getlocaleinfoa(GetThreadLocale, LOCALE_SSHORTDATE, b, sizeof(b)) > 
0 then
      writeln('GetThreadLocale:',b);  
end;

In Windows XP/Vista returns:
LOCALE_USER_DEFAULT:d. M. yyyy
LOCALE_SYSTEM_DEFAULT:d. M. yyyy
GetThreadLocale:d. M. yyyy                             <--IS OK

In Windows 7 returns:
LOCALE_USER_DEFAULT:d. M. yyyy
LOCALE_SYSTEM_DEFAULT:d. M. yyyy
GetThreadLocale:M/d/yyyy                                 <--HERE IS PROBLEM

So because calls to getlocaleinfo with argument GetThreadLocale is used 
to initialize DefaultFormatSettings, in Windows 7 are some locale 
specific global variables (ShortDateFormat, DateSeparator etc.) 
initialized incorrectly.
Has anybody else this experience ?

Now I find:

 http://stackoverflow.com/questions/1767946/getthreadlocale-returns-different-value-than-getuserdefaultlcid

So can you fix this problem somewhere in initialization process ?
Thanks
