Hello Freinds, I want to transfere one structure from client to server. structure contains one String and INT data, INT is the length of that string. I am trying send(); function of CSocket to transfere the structure but I am getting some garbage at server end and missing my strings address. Can anyone pl's help me. I have dought that the function I am using may not be currect. Thanks. Dinesh.

why don't you directly transfered the string to the server!,as
recvwinsock api returnd with total length of data recieved. something like this way, i am giving win32 based code Client End:char szString="Codeproject";
UINT nszLen=strlen(szString)+1;//Extra NULL character
send(hSendingSocket,szString,nszLen,0);Server End
char szString[1024];
int nTotalBufferLen=1023;//one for NULL character//recv data
int nRecv=recv(hRecvingSocket,szString,nTotalBufferLen,0);//complete string
szString[nRecv]=NULL;

Dinesh, I recommend using
CSocketFileandCArchive. They work beautifully! :cool: /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com -

Hi friend, Maybe the problem is that, if you are using TCP/IP protocol, the structure is divided as multiple packets on the network, so you should first send the size of the structure (string + int), then use recv() and check that the number of bytes received are equal to the size of the structure before using the structure, or USE UDP/IP. something like this:
int nRecv=0; while(nRecv //now i am sure i received the whole message, not just few packets //now use the structure Mohammad Gdeisat -
