Re: copy pointer CSocket class
That's because CSocket doesn't have a = operator (for good reasons). Trying
to copy a CSocket object to another is fatal. Because two CSocket objects
can't have the same SOCKET handle. Among other things (which I'm sure Joe
will list) the SOCKET handle is closed when the destructor of the
CAsyncSocket class is called. So when temp is destroyed so would be the
handle stored in Temp1.
Trying to copy any MFC object that deals with a handle is going to be bad.
You should reconsider your design to eliminate copying the CSocket object.

Hi MFC Gurus,
I have some problems which I need to copy a pointer of class object
(derived from CSocket).
I am using operator = so that I could use temp1=temp; //both are
objects from the same class.
so that when temp is destroyed, I would still have temp1 data.
however, this is not working since when I use temp1->Send(data, size);
it is not invoking anything in client appl.
Thank you.
Regards,
Rehmet
Code:
class mysocket : public CSocket
{
public:
CDialog *dlg;
CString name;
mysocket();
virtual ~mysocket();
void setparent(CDialog *dlg);
virtual void OnAccept(int errcode);
virtual void OnReceive(int errcode);
virtual void OnClose(int errcode);
mysocket& operator=(const mysocket& clonethis)
{
if(this==&clonethis)
return *this;
this->dlg=clonethis.dlg;
}
};
