Thanks that seems to do the trick.
Do you know how to handle ctrl-key input?
I can get when the user press ctrl and when a user press another one. Do I need to keep track if the ctrl is pressed or is there a predefined way to do that, multiple key input?
Cheers

Hi,

I don't know. I just answered his question..
I know it is possible though. You can read and write ethernet packets without any special voodoo. And ICMP packets are quite easy to construct as well, so I do know that it is not impossible.

I know that the answer is yes too but , if i really dont know how to do it, then no point in replying the question.

Thanks Mr.Prakash.
But, the source code you specified is using socket commands
like gethostbyname,WSAStartup...

Hi,
I am writing a P2P chat application. It allows two persons to communicate with each other over the internet using their IP addresses. The application works fine when both users are directly connected to the internet. but if one user is behind a firewall or proxy, the application does not connect. I understand that I have to bypass the proxy using SOCKS protocol. I want to ask is there some class or other method, that does this for me, that is, any implementation of the SOCKS protocol. I am using Visual C++ 6.0.

hy, i have a virtual function in a class. i must go sure, that every class who is inherited from this class overwrites this function, otherwise a warning shoud occur at runtime, or something like that. is this possible??
thanx andreas

|

in the base class make the functino pure virtual
like
virtual void somefunction() = 0; //pure virtual function.
this ensures that the derived class has to override/implement the method.
|
|
|
|
|
yes, but i need a technique, who workes also when i derive a class from a derived class and so on!
is there any trick?
|
|
|
|
|
Please do read about pure virtual function.
|
|
|
|
|
yes, but what, if i make a pure virtual function (abstract class) then derive a class from it, and implement this function. now i derive a class from this class, and forget to overwritte this function, how will i know?

It will cause a compile error.

It doesnt for the second derivation.
|
|
|
|
|
there is no complie error(on the 2th. deriv)!!!
is there any trick, or technique, that could give me
a compile error?
|
|
|
|
|
If you derive the class from CObject in MFC then i guess you can use the RTTI to determine which object's method is called and then generate the error accordingly.
|
|
|
|
|
so it would be possible that, whenever someone is calling the function, who is not overwritten (and therefore the one of the superclass is called) it throws an error?
that would be grat!
|
|

|

Maybe some light.
Any function has its start address. So you can check whether the start address of the function in the derived class is the same as the address of the function in the super class itself. If so, you could fault on runtime.
It has some difficulties, and some knowledge of vtables seem to be handy here, but I think it is in the direction you should be thinking.

No.
This is a very serious design flaw in C++.
(It gets worse. Say you created a function of the same name in the inherited class, but very slightly changed one of the parameters. You're screwed.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.
