Windows 加法计算器.doc

实验报告1 任务概述（任务说明） 设计一个计算器2设计思路(包括技术基础等) 先画出文本框EDIT，在画出按键BUTTON，接受数据后再转换成数据类型int，最后将运算后的结果又粘贴到文本框中。3程序结构描述4源码，文档化加法计算器.h#pragma once#include resource.hResource.h/NO_DEPENDENCIES/ Microsoft Visual C+ generated include file./ Used by 加法计算器.rc/#define IDS_APP_TITLE103#define IDC_EDIT1 1001#define IDC_EDIT2 1002#define IDC_EDIT3 1003#define IDC_BUTTON1 1004#define IDC_BUTTON2 1005#define IDC_BUTTON3 1006#define IDC_BUTTON4 1007#define IDR_MAINFRAME128#define IDD_MY_DIALOG102#define IDD_ABOUTBOX103#define IDM_ABOUT104#define IDM_EXIT105#define IDI_MY107#define IDI_SMALL108#define IDC_MY109#define IDC_MYICON2#ifndef IDC_STATIC#define IDC_STATIC-1#endif/ 新对象的下一组默认值/#ifdef APSTUDIO_INVOKED#ifndef APSTUDIO_READONLY_SYMBOLS#define _APS_NO_MFC130#define _APS_NEXT_RESOURCE_VALUE129#define _APS_NEXT_COMMAND_VALUE32771#define _APS_NEXT_CONTROL_VALUE1000#define _APS_NEXT_SYMED_VALUE110#endif#endif#define IDI_CALWINAPI107#define IDI_SMALL108#define IDC_CALWINAPI109#define IDC_MYICON2#ifndef IDC_STATIC#define IDC_STATIC-1#define IDC_EDIT1 1001#define IDC_EDIT2 1002#define IDC_EDIT3 1003#define IDC_BUTTON1 1004#define IDC_BUTTON2 1005#define IDC_BUTTON3 1006#define IDC_BUTTON4 1007#endif加法计算器.cpp/ 加法计算器.cpp : 定义应用程序的入口点。/#include stdafx.h#include #include Resource.h#define MAX_LOADSTRING 100/ 全局变量:HINSTANCE hInst;/ 当前实例TCHAR szTitleMAX_LOADSTRING;/ 标题栏文本TCHAR szWindowClassMAX_LOADSTRING;/ 主窗口类名/ 此代码模块中包含的函数的前向声明:ATOMMyRegisterClass(HINSTANCE hInstance);BOOLInitInstance(HINSTANCE, int);LRESULT CALLBACKWndProc(HWND, UINT, WPARAM, LPARAM);INT_PTR CALLBACKAbout(HWND, UINT, WPARAM, LPARAM);int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)UNREFERENCED_PARAMETER(hPrevInstance);UNREFERENCED_PARAMETER(lpCmdLine);
