Windows Forms의 소켓 코드 C++

Question

서버 모드에서 실행되는 제 3 자 프로그램과 간단한 프로젝트를 위해 Windows Forms를 사용하는 프로젝트를 통합해야하므로 소켓이 필요합니다. 다음은 관련 코드는 다음과 같습니다

complier는 아무런 불평을하지 않지만 프로그램이 제대로 작동하지 않습니다. 소켓이 단순히 작동하지 않고 버튼을 클릭해도 아무 반응이 없습니다. 아이디어가 있으십니까? 나는 어떤 의견이라도 정말로 고맙게 생각한다.

괜찮아 난 당신이 @Mgetz을 제안 그것을 구현하려고 노력하지만, 여전히 문제가있는 것 같다 :

#pragma once 

using namespace System::Net::Sockets; 
using namespace System; 

ref class PanguConnect 
{ 
private: 
    TcpClient ^mTcpClient; 

public: 
    PanguConnect(void); 
    void Connection(System::String^ server, Int32 port); 
    void CloseConnection(); 
}; 

#include "PanguConnect.h" 
using namespace System::Net::Sockets; 
using namespace System; 

PanguConnect::PanguConnect(void) 
{ 
} 

void PanguConnect::Connection(System::String^ server, Int32 port) 
    {   
     mTcpClient = gcnew TcpClient(server, port); 

    } 

void PanguConnect::CloseConnection() 
{ 
    mTcpClient->Close(); 
} 

사용자 인터페이스 부분 :

이

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { 
       PanguConnect PC; 
       try{     
        PC.Connection("localhost",10363); 
        } 

       catch(Exception ^e) 
       { 
        MessageBox::Show(e->Message); 
       } 


       try 
       { 
        PC.CloseConnection(); 
       } 

       catch(Exception ^e) 
       { 
        MessageBox::Show(e->Message); 
       } 
      } 

내가 오류는 다음과 같습니다 대상 컴퓨터에서 적극적으로 거부 한 연결이 없습니다 : 127.0.0.1:10363. 개체 참조가 개체의 인스턴스로 설정되지 않았습니다. :(

이 기능은 실제로이 직접 윈속을 사용할 필요가 없으며에 - 사실 그렇게 할 더 위험은 .NET 프레임 워크에 직접 구현되는

Answer 1

.

using namespace System::Net::Sockets; 

public ref class PanguConnection 
{ 
    private: 
    System::Net:Sockets::TcpClient mTcpClient; 

    public: 
    PanguConnection(System::String^ server, Int32 port) 
    { 
     this->mTcpClient = gcnew System::Net::Sockets::TcpClient(server, port); 
    } 
} 

주 당신이 있었다 발견 이 TCP를 사용하므로 System::Net::Sockets::TcpClient이 작동해야합니다.
