double-post, because I got an error message first :(

I only develop the server. The client is working well with other servers and it is open source.

Hello, I always lose the connection to a client, when I send data and want to receive data again. I don't know why. :( 1. AcceptEx() 2. ReadFile() <- at this point I received the last data 3. WriteFile() <- I think I lose the connection at this point! 4. ReadFile() 5. WriteFile() 6. ReadFile() . . . ---- What am I doing wrong? ;) I hope you can help me, bond006

I don't know how I solved the problem. I didn't use malloc and I had no static variables in the class. It was a quite weird problem.

I solved the problem, but I got a new problem. ;) I'm able to send the return packet and I'm able to call WSARecv() on the socket, but I always receive the data, I sent. ;) What's this???

Hello, I want to receive data after an AcceptEx() call. A brief overview: 1. I listen on a port and receive data with the buffer I've passed to AcceptEx(). 2. When there is incoming data I process the data and send a return packet. 3. Now I wan't to receive data from the same connection again. I tried to use WSARecv() on the socket, but everytime I use WSARecv() I get an error with the error code 10014 (The system detected an invalid pointer address in attempting to use a pointer argument in a call). When I create a new socket with the socket(), bind(), listen() accept() procedure and pass it to the WSARecv() function I have no problem in calling WSARecv(), but I wan't to receive data from the socket on which I sent data. Can I use AcceptEx(), send() and then WSARecv() in this order??? How would you do this? ----------------- Thank you for your attention, bond006

Hello, I've created a program which is waiting for incoming network connections via I/O Completion Ports and I've created a pointer in the network class to a packet processing class which's object is created outside of the class on the heap memory. All the things worked fine, but I got an error. No compiler or linker error - no error at all, but GetQueuedCompletionStatus() doesn't receive completed packets, when I add a specific number of bytes (in variables) in the Packet Processing Class. What's this??? Memory problems? Other problems? The Processing Class do nothing - an object of it is just created - that's all and the Packet Processing class has no relation to the Thread Function which is call the GetQueuedCompletionStatus() function. I can only add a WSABUF variable plus 3 bools and 1 short. That's all. What do you think is the error? Thanks for your attention and your help, bond006

Which socket? The listener socket or the accept socket? ;) When I close the listener socket I have no sockets at all! :) bond006

I'm not sure if I understood you, but that's quite simple. An example: ------------------------------------------ #include #include #include void main() { char singleLetter; bool wordCompleted = false; unsigned int numOfLetters; unsigned int numOfGuessedLetters = 0; cout << "Number of letters: "; cin >> numOfLetters; char* pArray1 = new char[numOfLetters+1]; char* pArray2 = new char[numOfLetters+1]; memset(pArray2,'_',numOfLetters); pArray2[numOfLetters] = '\0'; cout << "Type in the word: "; cin >> pArray1; system("cls"); // Should the other player see what word we've typed in? ;) while(wordCompleted==false) { cout << "Type in a letter: "; cin >> singleLetter; for(unsigned int i=0;i

That's quite simple! :) Try something like this: // ------------------------------------------------------ #include UINT threadID; unsigned WINAPI ThreadFunc(LPVOID param); void main() { CPCICard pPCICard = new CPCICard(); _beginthreadex(NULL,0,ThreadFunc,NULL /*that's the parameter for the ThreadFunc*/,0,&threadID); DoSomeWorkBlablabla(); delete pPCICard; } unsigned WINAPI ThreadFunc(LPVOID param) { DoSomeThreadWork(); RunningLoop(); return 0; } // --------------------------------------------------- I don't know whether I helped you or not, but when you call _beginthreadex the ThreadFunc function is called and then two threads running on the same time, doing different things. :) bond006

This assessments remind me of those Cisco CCNA assessments. eeem let's see. One question - four answers - the chance is 1:4 that I choose the right answer. ;) Not bad! By the way: I know nothing about Rich Client. What is it good for? ;) bond006

$10,000??? Uuuh - that's quite a lot money! ;) Don't do this at home kids. What drives him so crazy to do that?

Hello, I have a little problem on re-using a socket after a completed AcceptEx call. The number of maximum clients is equal to the number of sockets in my program. On every socket I made an AcceptEx() call to accept a new connection and receive the data. So far so good. After receiving the data I need a new AcceptEx() call which can receive data from other clients who are trying to connect. But - something is going wrong! When I simply recall AcceptEx() on the same listener socket and the same accept socket I get an error (WSAEINVAL / 10022L). Do I have to close the socket before I try to make a new AcceptEx() call on that socket? I would like to re-use this socket and leave it open, because it's queued in a completion port. I hope you can help me. Thanks for your attention! bond006
