    Apending to a .dat File using ofstream

    Hey evrbdy, Iam.TheJinx(who *cares);

    Alas, another problem has arisen in my desparate attemp at VC. I am tryig to use the ofstream method of appending to a file. What is wrong with this source:
    (Already declared the CStrings m_str's below, IDC_NAME is an Edit Box, and make sure to #include fstream.h)


    void::OnSave()
    {
    char m_strName[100];
    CDataDlg::GetWindowText(IDC_NAME, <--need help here-->);

    <--Something to put the IDC_NAME string to strName[100];-->

    ofstream dFile;
    dFile.Open("data.dat");
    dFile<<"Name: "<<m_strName<<"\n";
    dFile<<"-------------------------------\n\n\n";
    //etc. of dFile<<".." below
    dFile.close();
    }
    Weeel, itss aboot tieme wee goo back too Canada, eeehy boyss.

    try:

    Open("filename.dat", ios::out | ios::app);

    to open a ofstream in append mode

    Code:
    void::OnSave() 
    {
         //Get the text
         CString Var1 = m_strName.GetWindowText();//Easy way to do it
    
         //Output to file
         ofstream dFile; 
         dFile.Open("data.dat", ios::out | ios::app); Added from The V
         dFile<<"Name: "<<Var1<<"\n"; //Made change here
         dFile<<"-------------------------------\n\n\n"; 
         //etc. of dFile<<".." below 
         dFile.close(); 
    }
