求助一个用MFC来编写的计算器程序代码

Answer 1

主代码如下。。这个是我自己做的。就怕你看不懂了。。。 不过敢上来问，应该是比较精通的了。。 #include "stdafx.h" #include <stdio.h> #include <stdlib.h> #include <windows.h> #include <windowsx.h> #include "resource.h" #include "MainDlg.h" #define TURE 1 #define FALSE 0 BOOL WINAPI Main_Proc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) { switch(uMsg) { HANDLE_MSG(hWnd, WM_INITDIALOG, Main_OnInitDialog); HANDLE_MSG(hWnd, WM_COMMAND, Main_OnCommand); HANDLE_MSG(hWnd,WM_CLOSE, Main_OnClose); } return FALSE; } BOOL Main_OnInitDialog(HWND hwnd, HWND hwndFocus, LPARAM lParam) { return TRUE; } BOOL IsInt(TCHAR* str) { int i=atoi(str); TCHAR strtemp[256]; wsprintf(strtemp,"%i",i); if(strcmp(str,strtemp)==0) { return TURE; } else { return FALSE; } } TCHAR str1[256],str2[256],str3[256]; int i1,i2,i3; void Main_OnCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify) { switch(id) { case IDC_OK: { GetDlgItemText(hwnd,IDC_EDIT1,str1,sizeof(str1)); GetDlgItemText(hwnd,IDC_EDIT2,str2,sizeof(str2)); int i1,i2,i3; if(!IsInt(str1)) { MessageBox(hwnd,TEXT("第一个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } if(!IsInt(str2)) { MessageBox(hwnd,TEXT("第二个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } i1=atoi(str1);i2=atoi(str2);i3=i1+i2; wsprintf(str3,"%i",i3); SetDlgItemText(hwnd,IDC_EDIT3,str3); } break; case IDC_OK2: { GetDlgItemText(hwnd,IDC_EDIT4,str1,sizeof(str1)); GetDlgItemText(hwnd,IDC_EDIT5,str2,sizeof(str2)); if(!IsInt(str1)) { MessageBox(hwnd,TEXT("第一个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } if(!IsInt(str2)) { MessageBox(hwnd,TEXT("第二个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } i1=atoi(str1); i2=atoi(str2); i3=i1-i2; wsprintf(str3,"%i",i3); SetDlgItemText(hwnd,IDC_EDIT6,str3); } break; case IDC_OK3: { GetDlgItemText(hwnd,IDC_EDIT7,str1,sizeof(str1)); GetDlgItemText(hwnd,IDC_EDIT8,str2,sizeof(str2)); if(!IsInt(str1)) { MessageBox(hwnd,TEXT("第一个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } if(!IsInt(str2)) { MessageBox(hwnd,TEXT("第二个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } i1=atoi(str1);i2=atoi(str2); i3=i1*i2; itoa(i3,str3,10); SetDlgItemText(hwnd,IDC_EDIT9,str3); } break; case IDC_OK4: { GetDlgItemText(hwnd,IDC_EDIT10,str1,sizeof(str1)); GetDlgItemText(hwnd,IDC_EDIT11,str2,sizeof(str2)); if(!IsInt(str1)) { MessageBox(hwnd,TEXT("第一个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } if(!IsInt(str2)) { MessageBox(hwnd,TEXT("第二个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } i1=atoi(str1); i2=atoi(str2); i3=i1/i2; itoa(i3,str3,10); //else str3="除不掉";这里仍然有个bug! SetDlgItemText(hwnd,IDC_EDIT12,str3); } break; case IDC_OK5: { GetDlgItemText(hwnd,IDC_EDIT13,str1,sizeof(str1)); i1=atoi(str1); itoa(i1,str2,2); SetDlgItemText(hwnd,IDC_EDIT14,str2); } break; case IDC_OK6: { GetDlgItemText(hwnd,IDC_EDIT15,str1,sizeof(str1)); if(!IsInt(str1)) { MessageBox(hwnd,TEXT("第一个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } if(!IsInt(str2)) { MessageBox(hwnd,TEXT("第二个数不是整数!"),TEXT("错误"),MB_OK|MB_ICONERROR); return ; } i1=atoi(str1); itoa(i1,str2,16); SetDlgItemText(hwnd,IDC_EDIT16,str2); } break; default: break; } } void Main_OnClose(HWND hwnd) { EndDialog(hwnd, 0); }
