Thanks Dor.
What puzzles me is that when I am inserting, no probs at all.
But I leave it idle for a couple of days and this happens Frown | :-(

p.s. I have added the check to see that the socket accept(...) returns is a valid socket. Hopefully, that should solve it Smile | :)

There are different types of proxies :-

HTTP proxy
SMTP proxies
POP3 proxies
SOCKS proxies
Telnet proxies

Each cater to the needs of the underlying protocol

Hi,
I'd once read the source code of SQUID.. you can try that
out.. its a little tricky.. coz of Call back functions.

But give it a try!

Hi,
Squid is a Proxy server for Linux.. and it is Open
Source, I had once modified the source code of
squid.. Its a 40,000 lines of Code so you better
read its Squid Programming Guide, before you
read the source code.

BTW what exactly do you want to know about proxy servers.

Function() question...

ok... a functoin is declaring somthng like

voide SetName(char Name)
{
}
correct?

then if you want to use that in your program you could do somthing like
int main()
{
SetName("Judy")
return 0;
}

now... even though this wont do anything... "because there isnt anything int eh SetName function... this would work right?

i declared my void SetName(char Name); in a header class named Student so:

void Student::SetName(char Name);
{
}

int main()
{
char SName[32];
cin >> SName;
SetName(SName);

return 0;
}

wouldnt this work... what am i forgetting... i keep getting a undeclared identities thing.

Thanks all!

void Student::SetName(char* Name);
{
}

You would actually need to remove the semicolon:

void Student::SetName(char* Name)
{
}

You are passing a char* to a char.
Change the char to char* in your function's argument list

A global function, yes.

SilverShalkin wrote:

SetName("Judy")
return 0;

So long as it was visible to main, i.e. declared before it or forward declared.

You can only call this function on a student, there is no global function of this name. If you made the function static, you could call it on Student itself, otherwise you need to create a student and call the method.

Student s;
s.SetName("a") // You allowed a char, which is one character

Yeah, but at least I spotted why he couldn't access the function....

Seriously, you're right, of course. *blush*

The funny thing is that it might have worked for the guy if he casted it and he'd have used it without realizing it was a typo error

I was thinking that.. the only problem is that the student...

Student s

i will always keep adding students.. could i make s an array?
that always changes? like:

Student s[nextname];

?

Thanks All

No, you cannot do that - you can make an array of students ( or better yet, a std::vector ). That would be the point - each student knows what it's name is.
To make s an array you would put

Student [12] s;

( from memory )

why is the [12] behind s? And so i wouldnt beable to make the [12] into somthing that increases everytime you call it?

oh,... this project is a learning project... its not ment to go the easy path or anything, its ment for me to understand the class and using header. there is a couple other ways i probably could do this "me" you know, the guy that know the least on this forum... Smile | :)
