Regional Date Formats

[csi95]

Forgive me if this is an obvious question, but I've done hours of searching, and I can't figure this out.

VC++ 6 / Win32 platforms

I'm trying to use strftime with the %x option to give me a date in the format specified in the users Control Panel. Though I live in the US, for example, I may have told windows that I want to see dates as dd/mm/yyyy instead of mm/dd/yyyy.

It seems that no matter what I change -- local, format, etc., I get mm/dd/yy.

This is the code:

#include "stdafx.h"
#include <time.h>
#include <ctime>


int main(int argc, char* argv[])
{
time_t oTime;
tm* oDate;
char sThis[25];

time(&oTime);
oDate = localtime(&oTime);

strftime(sThis, 25, &quot;%x&quot;, oDate);

printf(sThis);
return 0;
}


Any ideas?

Is there a Windows API procedure that will accomplish this for me? Any help would be much appreciated.

Call setlocale() with LC_TIME before using strftime():
Example :

char *pLocale = setlocale(LC_TIME, &quot;German&quot;
if (pLocale)
{
// locale to German successfuly set
strftime();
//
}
See also _tzset() function for timezone environment variables.

obislavu -- thanks for the post. That's part of what I need. Now the question is, how do I know what locale the persons computer is set to?

In the Control Panel, a user can set their region, and also set any date, time and currency formating they like. My question is, how do I format the date based on their preferences?

There must be some Widows API call to do this, but I just haven't come across it yet.

Any ideas?

Use setlocale with NULL like here:
setlocale( LC_TIME, NULL );
and it returns the following string
LC_TIME=English_USA.1252
but to get more involved on that see the National Language Support Functions and use EnumDateFormat()
to get the date format.
