一、Hello客户服务器

1.在CodeBlocks里建立服务器端serv和客户端dialog WIN32 GUI工程

这里写图片描述

2.GUI 设计

打开Resource.rc进入设计界面，拖控件上来，保存，至于软件前面的作业有介绍
这里写图片描述

3.环境配置

serv工程和dialog工程分别在CodeBlocks里打开Project–>Build Options–>Linker settings进行如下配置
这里写图片描述

4.写代码

serv服务端：

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd){    hInst=hInstance;    InitCommonControls();    return DialogBox(hInst, MAKEINTRESOURCE(DLG_MAIN), NULL, (DLGPROC)DlgMain);}#include <windows.h>#include <windowsx.h>#include <commctrl.h>#include <stdio.h>#include "resource.h"#include <stdlib.h>#include <string.h>#include <Iphlpapi.h>#include <winsock2.h>HINSTANCE hInst;HWND button2;HWND button3;HWND list1;HWND edit1;WSADATA wsaData2;SOCKET hSocket;SOCKADDR_IN servAddr2;char message2[30];char name1[30],name2[30],check2[30];int strLen2;BOOL CALLBACK DlgMain(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam){    switch(uMsg)    {    case WM_INITDIALOG:    {        button2=GetDlgItem(hwndDlg,IDC_BUTTON2);        button3=GetDlgItem(hwndDlg,IDC_BUTTON3);        list1=GetDlgItem(hwndDlg,IDC_LIST1);        edit1=GetDlgItem(hwndDlg,IDC_EDIT1);    }    return TRUE;    case WM_CLOSE:    {        closesocket(hSocket);        WSACleanup();        EndDialog(hwndDlg, 0);    }    return TRUE;    case WM_COMMAND:    {        switch(LOWORD(wParam))        {        case IDC_BUTTON2:            if(WSAStartup(MAKEWORD(2, 2), &wsaData2)!=0)                printf("WSAStartup() error!");            hSocket=socket(PF_INET, SOCK_STREAM, 0);            if(hSocket == INVALID_SOCKET)                printf("socket() error");            memset(&servAddr2, 0 ,sizeof(servAddr2));            servAddr2.sin_family=AF_INET;            servAddr2.sin_addr.s_addr=inet_addr("127.0.0.1");            servAddr2.sin_port=htons(9091);            if(connect(hSocket, (struct sockaddr*)&servAddr2, sizeof(servAddr2))==SOCKET_ERROR)                printf("connect() error");            printf("连接成功..\n");            break;        case IDC_BUTTON3:            Edit_GetText(edit1,check2,30);            Edit_SetText(edit1,"");            send(hSocket, check2, sizeof(check2), 0);            memset(name1, 0, sizeof(name1));            strcat(name1,"我：");            strcat(name1,check2);            ListBox_AddItemData(list1,name1);            Sleep(1000);            memset(name2, 0, sizeof(name2));            memset(message2, 0, sizeof(message2));            recv(hSocket,message2,sizeof(message2)-1, 0);            strcat(name2,"我才不是机器人：");            printf("message2: %s\n",message2);            strcat(name2,message2);            ListBox_AddItemData(list1,name2);            break;        }    }    return TRUE;    }    return FALSE;}int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd){    hInst=hInstance;    InitCommonControls();    return DialogBox(hInst, MAKEINTRESOURCE(DLG_MAIN), NULL, (DLGPROC)DlgMain);}

dialog客户端：
