Hi,

I upgraded to boost version 1.43, but that did not help. Still file creation fails with wfstream and error code set is ERROR_FILE_NOT_FOUND.
Below code captures the error codes

#include "boost/filesystem/fstream.hpp"
int
main()
{
    boost::filesystem::path   pA("C:\\testA.txt");
    boost::filesystem::wpath  pW(L"C:\\testW.txt");
    boost::filesystem::fstream fileHandleA;
    boost::filesystem::wfstream fileHandleW;
    fileHandleA.open(pA, std::ios_base::out);
    cout << "fileHandleA.fail() return value is: " << fileHandleA.fail() << endl;
    cout << "Error code is: " << GetLastError() << endl;
    fileHandleW.open(pW, std::ios_base::out);
    cout << "fileHandleW.fail() return value is: " << fileHandleW.fail() << endl;
    cout << "Error code is: " << GetLastError() << endl;
    return 0;
}

Am I doing something wrong?

Regards,
Kiran
