Dear mathew, I was able to use FileSystemWatcher class ( suggested by u ) to
monitor events in a particular folder from ASP.net ! . ( Net is full of samples how u
can do the stuff for WinForm APPs ). In the Global class (derived from
System.Web.HttpApplication ) found in the Global.asax i added following code snippets
( in the Application_start method ) // filename is a static variable to pass
the fully qaulified path name to a static method.
// from a static method we cannot call server.mappath
filename = Server.MapPath("log.txt");
StreamWriter sw = new StreamWriter(filename);
sw.Write("------------------------------------\n");
sw.Close();
// in the Web.config file i added an entry in appSettings tag
//<appSettings>
//<add key="monitorpath" value="C:\FileSystemShare"/>
//</appSettings>
String PathToMonitor =
System.Configuration.ConfigurationSettings.AppSettings["monitorpath"]; // create an
instance of FileSystemWatcher object and assign path to monitor // set necessary
filters
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = PathToMonitor;
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch excel files
watcher.Filter = "*.xls";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true; OnChanged event handler will look like this
///////////////////////////////////////////////////////////
//
// Do Whatever u want here. I am just logging the
// info into the file.
//
//
private static void OnChanged(object source, FileSystemEventArgs e)
{
StreamWriter w = File.AppendText(filename);
w.Write("File Changed "+ e.ToString());
w.Close();
}
