I'm writing a vehicle management system, but do not know why to join this function after always have this problem, this function is read from a file the number of vehicles, vehicle number CAR: : count is a static variable, it is also be declared as static function, this function is to the number of the CAR are out,
In a digital file

The location of the calling function, in this
Void CPRODlg: : OnBnClickedButton1 ()
{
//registration information bounced
If (NULL==m_add)
{
M_add=new ADD ();
M_add - & gt; Create (IDD_ADDITION, this);

}
M_add - & gt; ShowWindow (SW_SHOW);
//read the number of vehicles
CAR: : count_read ();
}

}
}
