FILEWATCHER DESIGN APPS HOW TO

Now you should have a clear understanding of how to monitor the file system for changes using the. For it to fire we must add NotifyFilters.Attributes to the NotifyFilter values. If, for example, a change to a file attribute occurs, such as a file is set to read-only, the change event will not fire. If one of these changes occurs the fileSystemWatcher_Changed event will fire.

This line of code is telling the FileSystemWatcher to only watch for changes to file names and file sizes. You can combine these values using bitwise arithmetic as shown below:įileSystemWatcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.Size The security settings of the file or folder. The time the file or folder was created. The date the file or folder was last opened. The date the file or folder last had anything written to it. It can be set using any combination of the following values from the NotifyFilters enumeration: The NotifyFilter property allows you indicate which type of changes you want to monitor. That’s where the NotifyFilter property comes in. If many files are added to that directory at once our application could easily be swamped by an unceasing series of events. A screenshot of this can be seen below:Īs you can see from the screenshot above, whenever a file is added the FileSystemWatcher is firing a change event for the folder and two more for the file. When each of the above events fires, we are updating the main textbox ( txtStatus) with some text which describes the event. Private void fileSystemWatcher_Changed(object sender, FileSystemEventArgs e)

Next we must subscribe to its four events – the Changed, Created, Deleted, and Renamed events. The design hub is a comprehensive resource with opinionated guidance designed to empower designers and developers like you to create stunning and user-friendly interfaces for Android apps. We are starting the FileSystemWatcher by setting its EnableRaisingEvents property to true. MessageBox.Show('An error occurred: ' + ex.Message, 'Error', MessageBoxButtons.OK, MessageBoxIcon.Error) Īs you can see the code is quite self explanatory.

Also watch for changes within sub directoriesįileSystemWatcher.IncludeSubdirectories = true įileSystemWatcher.EnableRaisingEvents = true Private void btnMonitor_Click(object sender, EventArgs e)įileSystemWatcher.Path = () Next we’ll configure the FileSystemWatcher and start monitoring a folder in the Monitor button’s event handler. Then add a FileSystemWatcher component to your form from the Components Toolbox in Visual Studio. Let’s create an example which uses this component.Ĭreate a new Windows Forms Application project and design a form which looks similar to the one below: NET framework provides a component called the FileSystemWatcher which is designed to do exactly what its name suggests – watch the file system for changes.

When the original file is changed it would trigger an event and you can update the copy in the other location with the updated original file. A reason why you might want to do this is for example if you want to keep two files in different locations in sync. In this article I am going to show you how to monitor a folder for changes.
