get application data folder path

Hi everybody!

I need to find the path to the application data folder. So I use the function SHGetFolderPath with the CSID: CSIDL_APPDATA

Here is my code

Code:

---

#include <iostream>
#include <sstream>
#include <Windows.h> // for MAX_PATH
#include <shlobj.h> // for getFolderPath function
 
using namespace std;
 
// Convert TCHAR to string
std::string TcharsToString(TCHAR const * scz)
{
    #ifdef UNICODE
    std::ostringstream ossA;
    ossA << scz;
    return ossA.str();
    #else
    return scz;
    #endif
}
 
int _tmain(int argc, _TCHAR* argv[])
{
        cout << "Get Application Data"<< endl;
        string path="";
        TCHAR szPath[MAX_PATH];
        if(SUCCEEDED(SHGetFolderPath(NULL,
                            CSIDL_APPDATA,
                            NULL,
                            0,
                            szPath)))
        {
                path = TcharsToString(szPath);
        }
        cout << path << endl;
        system("PAUSE");
        return 0;
}

The problemm is that the string "path" contains series of characters with numbers like "0012FD24"

But normally, I would rather have a string like "C:\documents and settings\user\... , no?

Is there a problem with the conversion TCHAR -> String?

So, How could I have the path in return?

Thanks in advance for your answers

Does SHGetFolderPath() take care of null-termination for the TCHAR*? Is ostringstream overloaded for TCHAR*? I'm on a linux system right now, so I can't poke around.

What is you exact output?

My exact output is

0012FD24

SHGetFolderPath is a Win32 api : you can ask on Win32 api group for the official code (MS internal...)

I'm fairly sure the OP is calling SHGetFolderPath correctly. However, I highly doubt that std::ostringstream is overloaded for TCHAR * -- how could it be, since it's templated on char? (And TCHAR != char if Unicode is defined.)

OP: Why do you want to convert to a char */std::string? What character set do you expect the output in the char * to be?
