方法一。這種方式無法監視到檔案的修改，只有右鍵屬性中修改檔案的操作才能監視到。註冊 BOOL Register(HWND hWnd) { SHChangeNotifyEntry pfsne; LPITEMIDLIST pidl; if(NOERROR == SHGetSpecialFolderLocation(hWnd,CSIDL_DESKTOP,&pidl)) pfsne.pidl=pidl; pfsne.fRecursive = TRUE; if(m_dwSHNotify == 0) { m_dwSHNotify = SHChangeNotifyRegister(hWnd, SHCNE_DISKEVENTS, SHCNE_ALLEVENTS, WM_FILEMONITOR, 1, &pfsne); } return TRUE; } 反註冊 BOOL Unregister() { SHChangeNotifyDeregister(m_dwSHNotify); m_dwSHNotify = 0; return TRUE; } 自定義訊息 #define WM_FILEMONITOR WM_USER+100 資料結構定義 typedef struct { DWORD dwItem1; DWORD dwItem2; }SHNOTIFYSTRUCT; 標頭檔案中 afx_msg LONG OnFileMonitor(WPARAM wParam,LPARAM lParam); cpp檔案中 BEGIN_MESSAGE_MAP(CXXXDlg, CDialog) ON_MESSAGE(WM_FILEMONITOR, OnFileMonitor) //新增 END_MESSAGE_MAP() //檔案監控 ，自定義訊息的處理函式 LONG CXXDlg::OnFileMonitor(WPARAM wParam,LPARAM lParam) { SHNOTIFYSTRUCT *pNotify = (SHNOTIFYSTRUCT *)wParam; TCHAR szFileName[MAX_PATH*10], szNewFileName[MAX_PATH*10]; TCHAR szPath[MAX_PATH],szNewPath[MAX_PATH]; SHFILEINFO shFileInfo; memset(szFileName,0,MAX_PATH*10); memset(szPath,0,MAX_PATH); memset(szNewFileName,0,MAX_PATH*10); memset(szNewPath,0,MAX_PATH); if(pNotify->dwItem1) { SHGetFileInfo((TCHAR*)pNotify->dwItem1,0,&shFileInfo,sizeof(SHFILEINFO),SHGFI_PIDL | SHGFI_DISPLAYNAME); SHGetPathFromIDList((struct _ITEMIDLIST *)pNotify->dwItem1,szPath); wsprintf(szFileName,_T("Path:%s Name:%s "), szPath,shFileInfo.szDisplayName); // MessageBox(szFileName); } if(pNotify->dwItem2) { SHGetFileInfo((TCHAR*)pNotify->dwItem2,0,&shFileInfo,sizeof(SHFILEINFO),SHGFI_PIDL | SHGFI_DISPLAYNAME); SHGetPathFromIDList((struct _ITEMIDLIST *)pNotify->dwItem2,szNewPath); //LPCITEMIDLIST wsprintf(szNewFileName,_T("Path:%s Name:%s "), szNewPath,shFileInfo.szDisplayName); //MessageBox(szNewFileName); } switch(lParam) { case SHCNE_RENAMEITEM: //改名 break; case SHCNE_CREATE: //建立 break; case SHCNE_DELETE: //刪除 break; case SHCNE_MKDIR : //建立目錄 break; case SHCNE_RMDIR : //移除目錄 break; case SHCNE_RENAMEFOLDER: break; case SHCNE_ATTRIBUTES : //改變 break; } return 0; }
