客戶端服務器C++

我試圖建立一個客戶端服務器連接，我試圖從客戶端發送數據並通過服務器接收。我修改了互聯網上的程序，但結果並不令人滿意。客戶端和服務器之間的連接已建立，但客戶端無法將數據發送到服務器。客戶端服務器C++

有人能告訴我這些程序有什麼問題嗎？

int RetVal = 0;

if(RetVal != 0) 
{ 
    MessageBoxA(NULL, "Winsock startup failed", "Error", MB_OK | MB_ICONERROR); 
    exit(1);

sListen = socket(AF_INET, SOCK_STREAM, NULL);

addr.sin_addr.s_addr = inet_addr("127.0.0.1"); 
addr.sin_port  = htons(1234); 
addr.sin_family  = AF_INET; 

bind(sListen, (SOCKADDR*)&addr, sizeof(addr));

在服務器中，爲什麼要將SConnect設置爲一個值，然後用不同的值覆蓋該值？泄漏套接字！您在循環中的每次傳遞中都分配一個新的接收緩衝區，而您永遠不會釋放它。 – 2013-03-05 04:08:08

recv(Connections應該是recv(sConnect。查看我對您的問題的評論，以獲取代碼中其他更小的錯誤列表。
