ifstream wchar_t minGW c++

Question

I use eclipse with minGW 32. I created a class:

Data(HWND hwnd,  wchar_t szFileName[MAX_PATH])
{
std::vector<std::string> fileRows;  
    string sIn;
    ifstream infile;
    infile.open(szFileName);
    infile.seekg(0,ios::beg);

    // fill vector with file rows
    while ( getline(infile,sIn ) )
    {
       fileRows.push_back(sIn);
    }
}

but the ifstream in MinGW could not resolve the wchar_t. How can I store the file lines int the fileRows vector? Absolutely sure that the file lines are string not wstring. So I should store the lines in a std::vector<std::string>

I would avoid unicode filenames where possible. Meanwhile, read this: http://stackoverflow.com/questions/402283/stdwstring-vs-stdstring — paddy, Apr 02 '13 at 01:04

If you intend to read text data using wchar_t, use std::wifstream to read it and std::wstring to store it.

std::ifstream and std::string are designed specifically to use char.

Is it possible to convecrt my wchar_t szFileName[MAX_PATH] to char? – Carl Mark Apr 02 '13 at 01:28
@CarlMark That's both surprising and correct. http://stackoverflow.com/questions/1316962 – Drew Dormann Apr 02 '13 at 01:29

"*Is it possible...*" Take advantage of Stack Overflow! I could attempt an answer, but why not pose a new question to everyone? Good luck! :) – Drew Dormann Apr 02 '13 at 01:31
