    Writing to a File

    Quik noob question. Suppose I want to have my program out put a file called "Scores.txt" to the desktop what would the syntax be for doing that.
    I have the ofstream out_stream;
    but what would i put here -> out_stream.open ( "Scores.txt"); to get it to the desktop? As of right now it just writes it to the project dirictory. but i need it to go to the desktop.

    thx
    ben

    Code:
    #include <windows.h>
    #include <shlobj.h>
    #include <iostream>
    #include <fstream>
    #include <cstring>
    using namespace std;
    
    int main()
    {
        char desktop_path[MAX_PATH];
    
        // Get a token for this process. 
        HANDLE hToken;
        if (!OpenProcessToken(GetCurrentProcess(), 
                              TOKEN_IMPERSONATE | TOKEN_QUERY, &hToken))
        {
            cerr << "OpenProcessToken() failed, ec = " << GetLastError() << endl;
            return 1; 
        }//if
    
        // Get the desktop folder for the user of this process
        HRESULT res = SHGetFolderPathA(NULL, CSIDL_DESKTOPDIRECTORY, 
                                       hToken, 0, desktop_path);
        
        CloseHandle(hToken);
    
        if (!SUCCEEDED(res))
        {
            cerr << "SHGetFolderPathA() failed, ec = " << GetLastError() << endl;
            return 2;
        }//if
    
        strcat(desktop_path, "\\Scorse.txt");
    
        ofstream touch(desktop_path);
        touch.close();
    
        cout << desktop_path << endl;
    
        return 0;
    }//main

    thx codeplug. But i think thats a little advanced for me. Im just starting out and wrote a little program. Hers the part im trying to get to the desktop.
    Code:
    ofstream out_stream;
    	out_stream.setf(ios::fixed);
    	out_stream.setf(ios::showpoint);
    	out_stream.precision(2);
    	out_stream.open("Scores.txt");
    	out_stream << "Scores By: Kimberly" << endl<< endl;
    	out_stream << setw(48) << "* Service Scores *" << endl << endl;
    	out_stream << "Advisor" << setw(34) << "Score" << setw(37) << "Total Surveys" << endl;
    	out_stream << "-------" << setw(35) << "-------" << setw(36) << "-------------" << endl;
    	out_stream << "Jeremy " << setw(35) << Jeremy  << setw(31) << sJeremy <<endl;
    	out_stream << "Harry "  << setw(36) << Harry   << setw(31) << sHarry << endl;
    	out_stream << "Tina "   << setw(37) << Tina    << setw(31) << sTina << endl;
    	out_stream << "Louis"   << setw(37) << Louis   << setw(31) << sLouis << endl;
    	out_stream << "Mike "   << setw(37) << Mike    << setw(31) << sMike << endl;
    	out_stream << "Chris"   << setw(37) << Chris   << setw(31) << sChris << endl;
    	out_stream << "Antonio" << setw(35) << Antonio << setw(31) << sAntonio <<endl;
    	out_stream << "Gary "   << setw(37) << Gary    << setw(31) << sGary << endl;
    	out_stream << "Irene"   << setw(37) << Irene   << setw(31) << sIrene <<endl << endl << endl;
    	out_stream << "OSS " << setw(37) << "Rec." << setw(34) << "FRFT" << endl;
    	out_stream << "-----"  << setw(37) << "-----" << setw(34) << "-----" << endl;
    	out_stream << oss << setw(36) << rec << setw(34) << frft_score << endl << endl << endl;
    	out_stream << setw(48) << "* Sales Scores *" << endl << endl;
    	out_stream << setw(24) << "OSS" << setw(36) << "Rec." << endl;
    	out_stream << setw(24) << "-----" << setw(36) << "-----" << endl;
    	out_stream << setw(24) << sales_oss << setw(36) << sales_rec << endl << endl;
    	out_stream << setw(45) << "* VOC * " << endl;
    	out_stream << setw(44) << "-------" << endl;
    	out_stream << setw(43) << voc_score << endl << endl << endl;
    	out_stream.close();
    	cout << "Hit Any Key And Press Enter To Exit: ";
    	cin >> dummy;
    	return 0;
    }
    This is just a little console app that I wrote as im learning to program.(chapter 4) How could I get it to the desktop using this?

    Change
    >> out_stream.open("Scores.txt");
    to
    >> out_stream.open(desktop_path);
    and run the code that populates desktop_path before hand.

    As easy as it gets.

    That won't work on my machine....but feel free to hardcode the full path if you only care about it running correctly on your machine.

    Thanks codeplug and prog-bman for the help. I see what your saying about portability codeplug.But this program is just going to be on my wifes computer so it wont matter for now.but thanks for the code ill use it later when i get there.

    prog-bman that did the trick. I had the " \ " this way instead of this way " / ". once i changed it it wrote to the desktop.

    thanks to the both of you for the help I appreciate it.
