最近想好好研究C，于是便拿记事本这个小程序练练手。
自己从网上找了一个挺不错的，就从这个开始学习吧。。。。
一：代码
先建立一文件夹->方便管理与查看
拿我来说，在d盘根目录下新建note文件夹
1.新建一note.rc资源文件，代码如下。
#include "sample.h" A ICON MOVEABLE PURE LOADONCALL DISCARDABLE "sample.ico" MAINMENU MENU { POPUP "文件(&F)" { MENUITEM "打开(&O)...", CM_FILE_OPEN MENUITEM "另存为(&S)...", CM_FILE_SAVEAS MENUITEM SEPARATOR MENUITEM "关闭", CM_FILE_EXIT } POPUP "帮助(&H)" { MENUITEM "关于(&A)", CM_ABOUT } } |
2.新建sample.h,代码如下
#define CM_FILE_SAVEAS 9072
#define CM_FILE_EXIT 9071
#define CM_FILE_OPEN 9070
#define CM_ABOUT 9069
3.新建源程序note.c ,代码如下
#include <windows.h> #include "sample.h" static char g_szClassName[] = "MyWindowClass"; static HINSTANCE g_hInst = NULL; #define IDC_MAIN_TEXT 1001 BOOL LoadFile(HWND hEdit, LPSTR pszFileName) { HANDLE hFile; BOOL bSuccess = FALSE; hFile = CreateFile(pszFileName, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, 0); if(hFile != INVALID_HANDLE_VALUE) { DWORD dwFileSize; dwFileSize = GetFileSize(hFile, NULL); if(dwFileSize != 0xFFFFFFFF) { LPSTR pszFileText; pszFileText = (LPSTR)GlobalAlloc(GPTR, dwFileSize + 1); if(pszFileText != NULL) { DWORD dwRead; if(ReadFile(hFile, pszFileText, dwFileSize, &dwRead, NULL)) { pszFileText[dwFileSize] = 0; if(SetWindowText(hEdit, pszFileText)) bSuccess = TRUE; } GlobalFree(pszFileText); } } CloseHandle(hFile); } return bSuccess; } BOOL SaveFile(HWND hEdit, LPSTR pszFileName) { HANDLE hFile; BOOL bSuccess = FALSE; hFile = CreateFile(pszFileName, GENERIC_WRITE, 0, 0, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0); if(hFile != INVALID_HANDLE_VALUE) { DWORD dwTextLength; dwTextLength = GetWindowTextLength(hEdit); if(dwTextLength > 0) { LPSTR pszText; pszText = (LPSTR)GlobalAlloc(GPTR, dwTextLength + 1); if(pszText != NULL) { if(GetWindowText(hEdit, pszText, dwTextLength + 1)) { DWORD dwWritten; if(WriteFile(hFile, pszText, dwTextLength, &dwWritten, NULL)) bSuccess = TRUE; } GlobalFree(pszText); } } CloseHandle(hFile); } return bSuccess; } BOOL DoFileOpenSave(HWND hwnd, BOOL bSave) { OPENFILENAME ofn; char szFileName[MAX_PATH]; ZeroMemory(&ofn, sizeof(ofn)); szFileName[0] = 0; ofn.lStructSize = sizeof(ofn); ofn.hwndOwner = hwnd; ofn.lpstrFilter = "文本文件 (*.txt)\0*.txt\0所有文件 (*.*)\0*.*\0\0"; ofn.lpstrFile = szFileName; ofn.nMaxFile = MAX_PATH; ofn.lpstrDefExt = "txt"; if(bSave) { ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT; if(GetSaveFileName(&ofn)) { if(!SaveFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName)) { MessageBox(hwnd, "保存文件失败.", "错误信息", MB_OK | MB_ICONEXCLAMATION); return FALSE; } } } else { ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY; if(GetOpenFileName(&ofn)) { if(!LoadFile(GetDlgItem(hwnd, IDC_MAIN_TEXT), szFileName)) { MessageBox(hwnd, "打开文件失败.", "错误信息", MB_OK | MB_ICONEXCLAMATION); return FALSE; } } } return TRUE; } |
