FileSystemWatcher of file Monitoring (C + +)

In order to monitor the static file of the Web program is malicious change, so learned the FileSystemWatcher class to the file monitoring, because still in the initial stage, here only a few about FileSystemWatcher learning code.

The specific code is as follows:

#using<System.dll>#include<iostream>using namespacestd;using namespaceSystem;using namespaceSystem::IO;using namespacesystem::security::P ermissions; Public ref classwatcher{Private:   //Define the event handlers.   Static voidOnChanged (object^/*Source*/, filesystemeventargs^e) {//Specify what was done when a file was changed, created, or deleted.Console::WriteLine ("File: {0} {1}", E->fullpath, e->changetype); }   Static voidOnrenamed (object^/*Source*/, renamedeventargs^e) {//Specify what was done when a file was renamed.Console::WriteLine ("File: {0} renamed to {1}", E->oldfullpath, e->FullPath); } Public: [PermissionSet (SecurityAction::D emand, Name="FullTrust")]   int Staticrun () {//Array<string^>^args = System::environment::getcommandlineargs (); //creates a FileSystemWatcher and sets its properties.filesystemwatcher^ Fswatcher =gcnew FileSystemWatcher (); Fswatcher->path ="C:\\files"; /*Watch for changes in Lastaccess and lastwrite times, and the renaming of files or directories.*/Fswatcher->notifyfilter = static_cast<notifyfilters> (//the following properties of the listener file are added as required here I have added some commonnotifyfilters::lastaccess |//the date on which the file or folder was last opened. Notifyfilters::lastwrite |//The last date the content was written to a file or folderNotifyfilters::filename |//file nameNotifyfilters::D irectoryname |//Directory nameNotifyfilters::size);//size//Listen to subdirectoriesFswatcher->includesubdirectories =true; //Only watch text files. //fswatcher->filter = "*.txt"; //ADD event handlers.Fswatcher->changed + =gcnew FileSystemEventHandler (watcher::onchanged); Fswatcher->created + =gcnew FileSystemEventHandler (watcher::onchanged); Fswatcher->deleted + =gcnew FileSystemEventHandler (watcher::onchanged); Fswatcher->renamed + =gcnew Renamedeventhandler (watcher::onrenamed); //Begin watching.Fswatcher->enableraisingevents =true; //Wait for the user to quit the program.Console::WriteLine ("Press \ ' q\ ' to quit the sample." );  while(Console::read ()! ='Q' ); return 0; }};intMain () {Watcher::run ();}

Procedure 1. First create a FileSystemWatcher object to set some properties and add listener events

2. Setting the Listening directory

3. Setting the properties of a listening file

4. Setting up a listener subdirectory

5. Adding a listener Event

6. Start monitoring

The sample code above can be found on MSDN, and if you have an indeterminate place, you can view the document
