c#编应用程序，怎么监听其他进程（用c编写）的发来的消息？

在C#里兄猜重写

protected override void DefWndProc(ref Message m)

{

switch(m.Msg)

{

case YOUR MSGID:

//do your job

break

}

base.DefWndProc(ref m)

}或者实现IMessageFilter接羡吵型口碰扮

#include <iostream>

#include <stdlib.h>

#include <winsock2.h>

#pragma comment(lib, "ws2_32.lib")

using namespace std

//头文件包含

int main()

{ int recvbytes

char temp[100]

char a[100] //一些变量的声明

WORD wVersionRequested

WSADATA wsaData

SOCKET sock_id, client_id //定义两个套接字

struct sockaddr_in serv_addr, remote_addr//定义两个结构

wVersionRequested = MAKEWORD(2, 0)//这个是固定用法 版本

if (0 != WSAStartup(wVersionRequested, &wsaData)) //此处初始化socke库

{

cout <<"加载Winsock库出错!" <<endl

exit(1)

}

if (-1 == (sock_id = socket(AF_INET, SOCK_STREAM, 0))) //建立一个类型为TCP的套接字

{

cout <<"创建套接字出错!" <<endl

exit(1)

}

//填充结构体内容

serv_addr.sin_family = AF_INET//固定

serv_addr.sin_port = htons(800)//端口

serv_addr.sin_addr.S_un.S_addr = inet_addr("127.0.0.1")//ip

memset(&(serv_addr.sin_zero), 0, sizeof(serv_addr.sin_zero))//其他填充为零

//绑定到套接字描述符

if (SOCKET_ERROR == bind(sock_id, (struct sockaddr *)&serv_addr, sizeof(struct sockaddr)))

{

cout <祥旦<"1出错!" <<endl

exit(1)

}

//开始监听

if (SOCKET_ERROR == listen(sock_id, 5))

{

cout <<漏宴岩 "2出错!" <<endl

exit(1)

}

//如果来了一个连接请求 处理输入后发送给对方 输入的东东

int sin_size = sizeof(struct sockaddr_in)

if (SOCKET_ERROR == (client_id = accept(sock_id, (struct sockaddr *)&remote_addr, &sin_size)))

{

cout <<"3出错!" <<endl

exit(1)

}

cout<<"连接到一个客户端!!!请发送消息给他!!!"<<endl

cout<<"请输入要发送的消息!!!"<<endl

while(1)

{ cin>>a

send(client_id, a, strlen(a), 0)//把输入的东东发送出去

if (ERROR_SUCCESS == (recvbytes = recv(client_id, temp, 100, 0))) //接收数据到temp缓冲区

{

cout <<"接受数据出错!" <<endl

exit(1)

}

temp[recvbytes] = '\0'

cout <返御<temp <<endl

if(temp[0]!='8')

continue

else

break

}

closesocket(client_id)//关闭套接字

closesocket(sock_id)//关闭套接字

WSACleanup()//清理套接字库等收尾工作

system("pause")//暂停

return 0

}
