I could use a pointer, but what I really don't understand is when a person I met on IRC tried to compile some example code in VC++ 7.1, and it didn't report any errors. I use VC++ 7.0. Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

Server.h

class TcpServer
{
...
private:
static map<SOCKET, TcpServer> m_instances;
...
};

When I build this, the compiler reports this: error C2079: 'std::pair<_Ty1,_Ty2>::second' uses undefined class 'TcpServer' with [ _Ty1=const SOCKET, _Ty2=TcpServer ] Any solution? Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

I think you should go by select() then. It takes a parameter which specifies a timeout for the operation. You can also check out the WSAAccept() function. Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

I've been trying to read about the best network I/O model and talked to people about which network I/O model is the best. Different answers from different peopels about the same model. Asynchronous I/O: One says it's the best model for concurrent operations, an other says it's bad because of a lot of synchronizing/locking when access shared data (such as client list on a server), then a third says, locking is not bad...man, this is kinda confusing. Synchronous I/O - using select(): I would say this one is bad, because then you have to wait for each operation to copmplete before you can move on. Other people says this is a great network I/O model. What is your opinion about the best network I/O model? Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

When an object relates to another object using an asociation (or aggregation), does it mean it ALWAYS has a member varible of that "other" class? Like this:

----------- ----------------
| MyClass |----------| MyOtherClass |

class MyClass
{
private:
MyOtherClass moc; // Association
}

Or, could it also mean that MyClass for example access static member varibles/functions in MyOtherClass? Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

[quote] At my previous job, we were porting a UNIX system to Windows NT using Microsoft VC++. A colleague of mine, that was in the process of porting his portion of the code, came to me, looking really upset. * Colleague: "Hey! I hate these Microsoft guys! What a rotten compiler! It only accepts 16,384 local variables in a function!" [/quote] :wtf::wtf: Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

If an method would instantiate a local object that will do an asynchronous operation, how would that look in UML? A code snippet of what I want in UML is:

// C#
class MyClass
{
public DoOperation()
{
MyAsyncObject obj = new MyAsyncObj();
obj.StartSomethingAsynchronously();
}
}

If obj was a member varible the diagram would look something like this:

----------- 0..* -----------------
| MyCLass |<>--------->| MyAsyncObject |

Mr.Prakash wrote: VC++ compiles code writen in C++ so If you write something in C++ that VC++ cannot compile then its not a VC++ code. what ever that meant. You can write C code. And LRESULT CALLBACK Name(...) is a callback declaration of a C function callback, not C++. lauren said it's a static function, and because this is a (V)C++ forum C++ is the first hand language so a callback function is a static function (member function actually). Mr.Prakash wrote: and in VC++ CALLBACK is different not callback but CALLBACK (something the original poster has asked the question about). I hope now its clear. if so, lauren explained what a callback was? not the defination of CALLBACK... Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318

Mr.Prakash wrote: Is VC++ not C++ ?? :sigh: VC++ is a compiler. C++ is a language. In C++ (the language) you must declare a method as static before you can use as a callback. Rickard Andersson Here is my card, contact me later! UIN: 50302279 Sonork: 37318
