MFC读取txt文件内容的问题

Question

我把读取文件的代码写在Dlg的OnInitDialog()函数里
当那个data文件只有一行的时候读取文件是可以正常运行的，只在后面有问题。
但data文件有两行的话就会停在getdata函数这里
CStringData* GetData() const throw()
{
return( reinterpret_cast< CStringData* >( m_pszData )-1 );
}
读文件代码如下：

 CStdioFile myFile;
    CFileException fileException;
    if (myFile.Open(_T("data.txt"), CFile::typeText | CFile::modeReadWrite), &fileException)
    {
        myFile.SeekToBegin();
        CString str;
        while (myFile.ReadString(str)){
            single* fi = new single();
            int sec = 0;
            CString p;
            for (int i = 0; i < str.GetLength(); i++){
                if (str[i] == ','){
                    if (sec == 0)   //单号
                        fi->setNum(p);
                    else if (sec == 1){
                        if (p == "0") fi->setCategory(0);
                        else fi->setCategory(1);
                    }
                    else if (sec == 2)
                        fi->setSendAddr(p);
                    else if (sec == 3)
                        fi->setSendPhone(p);
                    else if (sec == 4)
                        fi->setSendNote(p);
                    else if (sec == 5)
                        fi->setReceiveAddr(p);
                    else if (sec == 6)
                        fi->setReceivePhone(p);
                    else if (sec == 7)
                        fi->setReceiveNote(p);
                    else if (sec == 8)
                        fi->setSendDate(p);
                    else if (sec == 9)
                        fi->setReceiveDate(p);
                    else if (sec == 10){
                        if (p == "0")
                            fi->setReceived(false);
                        else fi->setReceived(1);
                    }
                    else if (sec == 11){
                        if (p == "0")
                            fi->setUnknow(0);
                        else
                            fi->setUnknow(1);
                    }
                    else if (sec == 12){
                        int num = _ttoi(p);
                        fi->setUnknowNote(num);
                    }
                    else{
                        double mon = _wtof(p);
                        fi->setMoney(mon);
                        sec = -1;
                    }
                    p = "";
                    sec++;
                }
                else p += str[i];
            }
            tree->insert(fi);
        }
    }
    else
    {
        TRACE("Can't open file %s,error=%u\n", _T("data.txt"), fileException.m_cause);
    }
    myFile.Close();

求指教，这样写哪里有错吗？

当文件里有两行数据的时候断点调试下看看前一次读取的数据是否都正确，还有第二次确定下是卡在了哪里，看下堆栈调用窗口
