Greetings. This is my first post here

Firstly, i am wondering why you are sending text, rather than binary data. If you are generating the data, you can send information on the length etc.
For example, you can send a packet detailing what the following data is, and infer from that the length (you suggested this with the ''incoming:xxxx'' but it should be in the previous packet to your data).

If you don''t have control over the sent data, then the alternative that i use is to reallocate memory.

an example:

    /* example assumes you have already opened socket etc    also, this is a windows program - hence the windows memory    functions    sock is the socket.   the DataAvail function is one i wrote that uses select to check for data - i use blocking sockets & threads for preference. leave this check out if you are using asynchronous sockets and KNOW there is data.*/	char *pnt;	HANDLE Hdata;		int total=0;	do{if((Hdata=LocalReAlloc(Hdata,total+1024,LMEM_ZEROINIT))==NULL)		 return FALSE;		pnt=(char *)LocalLock(Hdata)+total;		if(DataAvail(sock))			len=recv(sock,pnt,1024,0);		else		{			closesocket(sock);			return FALSE;		}		LocalUnlock(Hdata);		total+=len;	}while(len>0);	printf("\nDone: %u characters received.\n",total);    

hope this helps/makes sense.

of course, you can disregard all of the previous, if, once you read in your data (128 bytes in a 256 byte memory block) you take into account that the return value from recv is the number of bytes recieved.

never send text data, unless it is a typed conversation or something. Do something like this

    struct MESSAGE{  int player;  int x;  int y;}MESSAGE myMessage;myMessage.player = 0;myMessage.x = 0;myMessage.y = 0;// on the sending sidesend(address, (char*)myMessage, sizeof(MESSAGE), otherParameter);// those arent all the parameters and they may not even be in the right order but you get the idea// on the receiving sideMESSAGE myMessage;receive(address, (char*)myMessage, sizeof(Message), otherStuff);// same comment as aboe on the send function    

now on the receive side
myMessage.player = 0;
myMessage.x = 0;
myMessage.y = 0;

hello!
i would like to use the code above (myMessage and so on) but if i tried to compile it, the compiler hangs at the send command
because he needs a char FAR pointer to the data and the conversion from int* to char* doesnt work... (char*)myMessage...

can anybody help me?
im using msvc++5

thanks for all

my fault it should be


send(address, (char*)&myMessage, sizeof(MESSAGE), otherParameter);

notice the address of operator in front of myMessage now
the same thing needs to be done in the recv function
