I dunno now how to fix it, also, you can recommend me a site for telling what is those errors?

Code:

  #if defined (_UNICODE) || defined (UNICODE)
#error "Unicode not supported - use Multi-Byte Character Set"
#endif

#include <windows.h>
#include <stdio.h>
#include <iostream>
#include <string>
#include <stdlib.h>
#include <sstream>

using namespace std;
string n;
string f1;
string flf;
string f2;
stringstream ss;
stringstream rr;

int main (void)
{
    WIN32_FIND_DATA FindFileData;
    HANDLE hFind;

    flf = "*.*";

    cout<<"Enter file's location: "<<endl;
    cin >> f1;

    rr = f1+flf;

    const char szInitialDir[] = (rr.str().c_str());

    printf ("Initial directory: %s", szInitialDir);
    hFind = FindFirstFileA (szInitialDir, &FindFileData);
    if (hFind == INVALID_HANDLE_VALUE)
    {
        printf ("Error: %lu ", GetLastError ());
        system ("pause");
        return EXIT_FAILURE;
    }
    do
    {
        printf ("\nFile: %s", FindFileData.cFileName);

    } while (FindNextFileA (hFind, &FindFileData));

    FindClose (hFind);
    system ("pause");

    cout<<"Witch you want to run?"<<endl;
    cin >> n;

    ss << "start " << f1 << n;
    system (ss.str().c_str());

    //the end

    return 0;

    return EXIT_SUCCESS;
}

error's:

Im new in c++, sorry for my english, this is not an homework, just an personal project! Thanks in advance!

rr = f1+flf; you can't assign a std::string to a std::stringstream.

rr << f1;
rr << flf;

Thank you but it fixed only 1 error, there's 2 more error's"

I still dunno now how to fix this :P
