Hi,

running the following code as an console application:

#include <locale>
#include <iostream>
#include <sstream>
#include <tchar.h>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
// ----------------------------------------
const char* arrLocaleNames[] = {
"German_germany",
"german-austrian",
"german-swiss",
"german-austrian",
"C",
"French",
"",
};
ostringstream* poStrStream = new ostringstream;
*poStrStream << "output of double a=1234.56E0 using different
locales:" << endl;
double a = 1234.56E0;
for (int i=0; i < sizeof(arrLocaleNames)/sizeof(arrLocaleNames[0]);
i++) {
poStrStream->imbue(locale( arrLocaleNames[i] ) );
*poStrStream << a << " <- locale(\"" << arrLocaleNames[i] << "\")
getloc().name():\"" <<
poStrStream- >getloc().name().c_str() << "\"" << endl;
}
// ----------------------------------------

cout << poStrStream->str();
delete poStrStream;

int k;
cin >> k;
return 0;
}

leads to the correct output:

output of double a=1234.56E0 using different locales:
1.234,56 <- locale("German_germany")
getloc().name():"German_Germany.1252"
1.234,56 <- locale("german-austrian")
getloc().name():"German_Austria.1252"
1'234.56 <- locale("german-swiss")
getloc().name():"German_Switzerland.1252"
1.234,56 <- locale("german-austrian")
getloc().name():"German_Austria.1252"
1234.56 <- locale("C") getloc().name():"C"
1á234,56 <- locale("French") getloc().name():"French_France.1252"
1.234,56 <- locale("") getloc().name():"German_Germany.1252"

But compiling the code between the two comment lines in a WinForms-project
as it is created by the VC2005-IDE using the same header files and namespace
std statement as above, results in the following output:

output of double a=1234.56E0 using different locales:
1234.56 <- locale("German_germany") getloc().name():"German_Germany.1252"
1234.56 <- locale("german-austrian") getloc().name():"German_Austria.1252"
1234.56 <- locale("german-swiss")
getloc().name():"German_Switzerland.1252"
1234.56 <- locale("german-austrian") getloc().name():"German_Austria.1252"
1234.56 <- locale("C") getloc().name():"C"
1234.56 <- locale("French") getloc().name():"French_France.1252"
1234.56 <- locale("") getloc().name():"German_Germany.1252"

Obviously the locale function produces the same output as in the console
version but the stream output stays with the standard "C" settings!

What do I have to change (compiler settings, move the piece of code out of
the click-handler of the WinForm) to get the correct results?

Thanks for your help

Rainer

Hello Rainer,

Yes, I've reproduced this and confirmed that it is a known problem with /clrure complilation.
Apparently, the numpunct <char> facet is being initialized from the "C" locale instead of the instantiated and imbued locale.
