    return registry subkeys values like vector TCHAR

    i have this code to list [COLOR=#0000ff !important][COLOR=#0000FF ! important]registry [COLOR=#0000FF ! important]key[/COLOR][/COLOR][/COLOR] values and subkeys

    TCHAR achKey[MAX_KEY_LENGTH]; // buffer for subkey name
    retCode = RegQueryInfoKey(
    hKey, // key handle
    achClass, // buffer for class name
    &cchClassName, // size of class string
    NULL, // reserved
    &cSubKeys, // number of subkeys
    &cbMaxSubKey, // longest subkey size
    &cchMaxClass, // longest class string
    &cValues, // number of values for this key
    &cchMaxValue, // longest value name
    &cbMaxValueData, // longest value data
    &cbSecurityDescriptor, // security descriptor
    &ftLastWriteTime); // last write time

    // Enumerate the subkeys, until RegEnumKeyEx fails.

    if (cSubKeys)
    printf( "\nNumber of subkeys: %d\n", cSubKeys);

    for (i=0; i<cSubKeys; i++)
    cbName = MAX_KEY_LENGTH;
    retCode = RegEnumKeyEx(hKey, i,
    if (retCode == ERROR_SUCCESS)
    _tprintf(TEXT("(%d) %s\n"), i+1, achKey);

    i want to return subkeys names like an array or vector of strings TCHAR,
    i tried:
    vector<TCHAR> getSubKeys(HKEY key)
        vector<TCHAR>> subkeys;
        for (i=0; i<cSubKeys; i++) 
            // get subkey name
        return subkeys;
    with this change it works but at t_main function when i try to list the vector to the console just show eight(the number of subkeys is correct) numbers like 65000 the same value for the eight vector elements, where's the problem or how can i compile with your code, thanks a lot
    thanks a lot

    A TCHAR is a *single* character. You need a vector of LPTSTR, each of which you will need to allocate and populate in your loop.
