    Question Win API file problem

    The following section of code is in my encryption programme that I am developing.
    If the file doesn't exist, there is no problem with writing the character string to the file.
    However, if I am overwriting the file, I cannot write the character string to the file. Just a blank file is produced.


    ofstream CiphertextF;

    CiphertextF.open(cipherfilename, ios:ut|ios::noreplace);
    if(!CiphertextF.is_open())
    {
    if(MessageBox(hwnd, "File Already Exists, Overwrite?","warning", MB_YESNO|MB_ICONQUESTION)==IDYES)
    CiphertextF.open(cipherfilename, ios:ut | ios::trunc);
    else
    break;
    }
    ....more code that is exectuted whether or not the file exists,
    ....including create ciphertext
    ....
    ....
    Ciphertextf<<ciphertextstring<<endl;



    any help would be much appreciated.
    Thanks,
    Donal
