ofstream input wchar_t

[askalottaqs]

dont freak out by length of code! its commented out befiore each block so you dont have 2 read it all..

so anyway! i have a fairly simple question i wld say, all i need is a little guide,

i am trying to write an input stream to write to files, but the file being opened needs to change with each for loop, so i did this

ofstream out;
 
 
for (int j=0;j<24;j++){
 
    /////////int to string
            string jAsString;
            stringstream smStrngStrm;
            smStrngStrm << j;
            jAsString = smStrngStrm.str();
 
 
    //file path in string format, to be cnverted to wchar_t
    string filePath = "geo";
    filePath += jAsString;
    filePath += ".cache";
 
 
 
    // First convert to a char*
    string cstring = filePath;
    const size_t newsize = 100;
    char pathChar[newsize];
    strcpy_s(pathChar, cstring.c_str());
    strcat_s(pathChar, " (char *)");
 
    // Then convert to a wchar_t*
    size_t origsize = strlen(cstring.c_str()) + 1;
    size_t convertedChars = 0;
    wchar_t wcstring[newsize];
    mbstowcs_s(&convertedChars, wcstring, origsize, cstring.c_str(), _TRUNCATE);
    wcscat_s(wcstring, L" (wchar_t *)");
    const char *pathAsChar = filePath.c_str();
 
 
    out.open(wcstring, ios::out);
 
        out<<wcstring[0]<<"\n";
    out<< sizeof(wcstring)<<"\n";
 
 
        for(int i=0;i!=meshVertices.length();++i) {
 
 
 
                out        //<< pathToGeo
                        << i << " "
                        << meshVertices[i].x <<" "
                        << meshVertices[i].y <<" "
                        << meshVertices[i].z <<"\n";
 
                }
 
 
    out.close();
 
    }

but it doesnt seem to be opening the file with the string name wcstring, and when i try to print it out, i mean the variable, i get some hexadecimal stuff, does anyone have a clue???? thanks

}


out.close();

}

I don't think you need to do all of that code to open the file:

    string filePath = "geo";
    filePath += jAsString;
    filePath += ".cache";
 
    out.open(filePath.c_str(), ios::out);
