socket-Fehler können keine Funktionen in WinSock2.h abrufen

Ich habe eine Socket-Wrapper-Klasse erstellt, aber ich habe zu viele Fehler, die ich nicht lösen kann. Ich habe versucht, Winsock Tutorial Fehler und Kann Winsock2.h nicht in MSVC 2010 aufnehmen, aber keine Verwendung

Hier ist der Code:

//#define WIN32_LEAN_AND_MEAN
#include <iostream>
#include <string>
#include <Windows.h>
#include <WinSock2.h>
#include <WS2tcpip.h>
#pragma  comment(lib,"ws2_32_lib")
using namespace std;
#define WM_SOCKET 0x10000

class Socket 
{


}; 

Hier sind die Fehler:

Sie müssen die Include-Dateien der Windows-Header wie folgt neu ordnen:

#include <WinSock2.h>
#include <WS2tcpip.h>
#include <Windows.h>

Mit anderen Worten, die WinSock-Header müssen vor Windows.h eingefügt werden.

Oder definieren Sie WIN32_LEAN_AND_MEAN, den Sie aus irgendeinem Grund auskommentiert haben.

Ich denke, Sie müssen auch die Accept-Methode ändern, um SOCKET statt Socket zurückzugeben.

Und der #pragma sollte sein:

#pragma comment(lib,"ws2_32")

Ich stellte sicher, dass ein #include "Winsock2.h" vor jedem #include "windows.h" und "#include" Winsock.h "steht und dieser Fall gelöst wurde.

Nur eine Frage der Geduld, schauen Sie sich die Includes nacheinander an und legen Sie diese Reihenfolge fest. Zuerst #include "Winsock2.h" und dann #include "windows.h"

Ich habe die rekursiven Includes überprüft, ich habe die Header-Dateien entdeckt, die (rekursiv) #include "windows.h" und "#include" Winsock.h "enthalten, und schreibe ein # include" Winsock2.h ". In diese Dateien fügte ich hinzu #include "Winsock2.h" `als erstes Include.

Sie können Windows.h nicht vor dem Einfügen von WinSock2 einschließen, da dies dazu führt, dass der Windows-Header eine ältere Version von Winsock enthält. Entfernen Sie das Windows.h-Include vollständig.

Siehe beispielsweise diesen MSDN-Link: http://msdn.Microsoft.com/en-us/library/windows/desktop/ms737629(v=vs.85).aspx Der Hinweis-Teil unter dem ersten Code Block erklärt das.
