Re: I got a strange error message when using fstream!

#include <fstream>
#include <iostream>
#include <vector>
using namespace std;

class MyObj {
public:
int data;
ifstream in;
};

typedef std::vector<MyObj> MyObjVector;

int main(int arc, char* argv[]) {
    MyObjVector myVector;

    MyObj obj;
    obj.data = 10;
    obj.in.open("test.txt");

    myVector.push_back(obj);
}

In the code above, I want to use a vector of class MyObj, which
have a ifstream object, but I got a message says that I can't
access the private memeber of ios_base, both in MinGW and Visual
C++, but if a commented the line
   myVector.push_back(obj);
all thing is OK, can't any one help me!
