    A couple of questions .. please read

    1. How can I get some info from the registry, and store it into a variable. i.e. I want to get the info on where the quake3.exe is located by going into the registry and get it, and then store it into the variable q3dir.

    2. After the a function returns the value 0, shouldn't it go back to main() then?

    3. What data type should I use in order to get blank spaces .. i.e. how do I store a string like "c:\program files"? when I try to have it as char it shows up as c:\program .. not program files.

    thanks

    Whithout any code, it is hard to get anyone to answer these questions, so post some code.
    Posting code shows that you are putting an effort into your project, which makes people willing to answer you.
    For starters, i dont understand what these questions have in common.
    Second, for question #2&3 get a little deper into programming and you will find these answers.

    umm .. they have something incommon when it comes to my app .. and if you want some code .. well here you go.

    #include <iostream.h>
    #include <stdlib.h>
    #include <conio.h>
    #include <windows.h>

    void clrscr()
    {
    COORD coordScreen = { 0, 0 };
    DWORD cCharsWritten;
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    DWORD dwConSize;
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hConsole, &csbi);
    dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
    FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
    GetConsoleScreenBufferInfo(hConsole, &csbi);
    FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
    SetConsoleCursorPosition(hConsole, coordScreen);
    }

    int end()
    {
    clrscr();
    return 0;
    }

    int start()
    {
    system("q3dir +set fs_game mod");

    return 0;
    }

    int setextra()
    {
    clrscr();
    cout << "### Ignite Q3 ### - by Teabag Productions";
    cout << "\n - Set Extra Options";
    cout << "\n\n # Please enter the dir name of the mod you want to play";
    cout << "\n # e.g. q3ut2";
    cout << "\n\n #:";
    char mod [99];
    cin >> mod;

    return 0;
    }

    int setloc()
    {
    clrscr();
    cout << "### Ignite Q3 ### - by Teabag Productions";
    cout << "\n - Set Location of Quake3.exe";
    cout << "\n\n # Please enter the full path of your quake3 executable";
    cout << "\n # e.g. c:\\quake III arena\\quake3.exe";
    cout << "\n\n #:";
    char q3dir [99];
    cin >> q3dir;

    // cout << q3dir;

    return 0;
    }

    int main()
    {
    clrscr();

    cout << "### Ignite Q3 ### - by Teabag Productions";
    cout << "\n\n ### MENU ###";
    cout << "\n\n #1 Set Location of .exe";
    cout << "\n #2 Set Extra Options";
    cout << "\n #3 Start Quake3";
    cout << "\n #4 Quit";
    cout << "\n\n #:";

    int MenuChoice;
    cin >> MenuChoice;
    if (MenuChoice == 1)
    setloc();
    else
    if (MenuChoice == 2)
    setextra();
    else
    if (MenuChoice == 3)
    start();
    else
    if (MenuChoice == 4)
    end();

    return 0;
    }
