FileSystemWatcher filter problem and how it works

[Xmen Real]

FSW dont raise event when i set its filter to custom extension, like if i set it to "*.abcd" then no event will raise but if i set it to other known extensions like "*.txt" or something else it works, any idea how to solve ? my second question is that how it works, is it works like timer mean it keep refresh after some inbuilt specified time or any window function send info to it when a file created and it raises event ? thanks

FSW monitors a directory for file creation, modification, deletion and renaming. The custom expression is to monitor only those file types that match that expression. This example monitors only the directory where dir == the directory to monitor and only raise an event on file types of txt.

fileWatcher = new FileSystemWatcher(dir, "*.txt");
fileWatcher.EnableRaisingEvents = false;
fileWatcher.IncludeSubdirectories = false;
fileWatcher.NotifyFilter = NotifyFilters.FileName;
fileWatcher.Created += new FileSystemEventHandler(fileWatcher_Created);

Set fileWatcher.EnableRaisingEvents = true to enable the monitoring. To stop monitoring set the value to false. http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx[^]

Just because we can; does not mean we should.

i know that, i think you didnt read my problem properly :) i said it dont raise any event when i set custom filter, for example if i write FSW.Filter = "*.abcd"; // wont work, if i create any file with extension abcd but if i write FSW.Filter = **.txt"; // will work, if i create any file with extension txt EDITED : SOLVED

Not sure where your having problems. I did this test and had no problems getting the notifications. Sorry

    private void Form1\_Load(object sender, EventArgs e)
    {
        fileSystemWatcher1 = new System.IO.FileSystemWatcher(@"C:\\");
        fileSystemWatcher1.IncludeSubdirectories = false;
        fileSystemWatcher1.NotifyFilter = NotifyFilters.FileName;
        fileSystemWatcher1.Filter = "\*.abcd";
        fileSystemWatcher1.Created += new System.IO.FileSystemEventHandler(fileSystemWatcher1\_Created);
        fileSystemWatcher1.Changed += new System.IO.FileSystemEventHandler(fileSystemWatcher1\_Changed);
        fileSystemWatcher1.Renamed += new RenamedEventHandler(fileSystemWatcher1\_Renamed);
        fileSystemWatcher1.Deleted += new FileSystemEventHandler(fileSystemWatcher1\_Deleted);
        fileSystemWatcher1.EnableRaisingEvents = true;

        File.Delete(@"C:\\test.abcd");
        StreamWriter sw = new StreamWriter(@"C:\\test.abcd",true);
        sw.WriteLine("test");
        sw.Close();
        sw.Dispose();
    }

    void fileSystemWatcher1\_Deleted(object sender, FileSystemEventArgs e)
    {
        MessageBox.Show("File Deleted " + e.FullPath.ToString());
    }

    void fileSystemWatcher1\_Renamed(object sender, RenamedEventArgs e)
    {
        MessageBox.Show("File Renamed " + e.FullPath.ToString());
    }

    void fileSystemWatcher1\_Changed(object sender, System.IO.FileSystemEventArgs e)
    {
        MessageBox.Show("File Changed " + e.FullPath.ToString());
    }

    void fileSystemWatcher1\_Created(object sender, System.IO.FileSystemEventArgs e)
    {
        MessageBox.Show("File Created " + e.FullPath.ToString());
    }
