Which indicates that AfxGetInstanceHandle() is being (indirectly) called but afxCurrentInstanceHandle is NULL. Are you using AFX_MODULE_STATE?

I don't know what is AFX_MODULE_STATE.
1. Can you explain what is it?
2. How can I find out if I am using it?

Search the .h and .cpp files used in your project.

Hi,
I'm trying to have a server application with listening socket on a defined port(e.g. 6000). The client application connects to the server on port 6000, and the server starts a new thread to deal with the client by creating a new socket also associated with port 6000. So what I want to happen is when the server gets a UDP on port 6000 if it is from the client then the socket in the spawned thread is used. If it is not from the original client then a new thread is spawned. Is this possible?
Thanks

No, I'm afraid you cant do this with datagram (UDP) sockets. you can do this with stream (tcp) sockets, by calling the accept() function, this will give you a new socket per connection, these sockets can then be passed to separate threads for processing.
The only way to do what you want is to have a single loop receiving packets with the recvfrom() function, this will return the address of the sender of the packet. then for each client, have a queue of that you put that packet into, have then a thread for each cleint that reads the next packet from the respective queue and processes it. Each thread can have a copy of the original socket handle so that they can send to their respective clients.
hope this helps.

Here's my next idea is this possible? The server has a UDP socket on port 6000 and spawns a new thread using creating a new socket using port 6001. By using the connect() method at the server the socket should filter all datagrams from all other clients. So in effect the server has multiple UDP sockets on port 6001.
Thanks

hmmm this may work, but the client would have to send the first packet to port 6000 and then all other packets to port 6001, what happens if the first packet doesnt arrive (udp is not reliable) at the destination and then the client will start sending to 6001 and the packets will get dropped.....
sounds like a bad plan to me.....

can anyone tell me the difference between ATL, WTL, STL, and MFC. What should I use when i develop general windows applications?
|
|
|
|
|
STL is a set of template classes and functions which provide generic containers and algorithms.
ATL is a set of template classes to create COM components and also contains default implementation of some COM interfaces.
WTL is a windowing wrapper over ATL to create template based window applications.

Hi,
I was wondering if anyone cold tell me how to send and receive data over a TCP/IP packets..etc....is there some kind of a winsock class in C++?
|
|
|
|
|
|
|
does anyone know where i can get a class to implement multithreading in c++. Im making a console application using Borland CBuilerX.
|
|
|
|
|
For starters, you won't find anything useful here for a Borland compiler, unless it is just plain C++ (which obviously knows nothing of threads).

One thing to note when installing VS6, is that the SDK that originally gets installed are out of date. I recently had to re-install VS6.0 and the first thing that I did was to install the latest service pack for VS6.0 (SP5 I think), and then download the latest Windows SDK and install those.
Having the windows XP operating system does not mean that you have the latest SDK installed. Go to the Microsoft website and search for the Windows Platform SDK. These updated files will contain all the new definitions that you need.

Hi,
I have a pointer *p. I would like to save its memory address in the variable "address" of type ULONG. Then I would like to create another pointer *q with this address. How can I do it?
Thank you

char* p;
ULONG address = (ULONG)&p;
char* q = (char*)address;
