Re: Problem reading vector<CString> from file.

I have created a class which contains a vector<CString> as a data member
class BillSlip
{
private:
     int ItemNameIndex;
     vector<double> Weight,Fine,Tch,Qty,Rate,Lab;
     vector<CString> ItemName;
     CString CustomerName;
     char BillNumber[100],Date[20];
     double Material_carry,Money_carry;
     double Material_paid,Money_paid;
     double Material_carry_left,Money_carry_left;
     double Material_debit,Money_debit;
public:
    /*member functions are also there*/
};
I write the class to a file using
 BillSlip BSlip;
 fstream BilF;
 BilF.open("c:\\BSl.txt",ios::out|ios::binary|ios::app);
 BilF.write((char*)&BSlip,sizeof(BillSlip));
 BilF.close();

and read the file in the following way:
BillSlipFile.open("c:\\BSlipRec.txt",ios::in|ios::binary|ios::app);
    BillSlipFile.read((char*)&BSlip,sizeof(BillSlip));
    MessageBox(BSlip.GetCustomerName());
    while(!BillSlipFile.eof())
    {
        BillSlipFile.read((char*)&BSlip,sizeof(BillSlip));
        MessageBox(BSlip.GetCustomerName());
    }
    BillSlipFile.close();
