Submitted by donbermoy on Sunday, May 10, 2015 - 23:48.
This tutorial will teach you how to create a program that will use the File Watcher component allowing files or disallow creating files or folder in vb.net. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add FileSystemWatcher in the form. Insert one textbox named TextBox1 to display the filename, a button named ButtonBrowse2 for browsing the files, button named ButtonAllow, and a button named Buttondontallow. You must design your interface like this: output 3. Now, lets do the coding. We will first code for our FileWatcher that will have the created as an event for this component.
  1.   Private Sub FileSystemWatcher1_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created
  2.  
  3.         If e.Name.Contains("\") = False And New FileInfo(e.FullPath).Extension = Nothing Then
  4.  
  5.             Directory.Delete(e.FullPath)
  6.         Else
  7.  
  8.             File.Delete(e.FullPath)
  9.         End If
  10.  
  11.     End Sub
For locating or browsing files and folders, put this code in your browse button.
  1.    Dim fbd As New FolderBrowserDialog
  2.  
  3.     Private Sub ButtonBrowse2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonBrowse2.Click
  4.         If fbd.ShowDialog() = Windows.Forms.DialogResult.OK Then
  5.             TextBox1.Text = fbd.SelectedPath
  6.         End If
  7.     End Sub
For allowing files or folders to be created, put this code for your allowed button. We will just use EnableRaisingEvents method of the FileWatcher to False.
  1.     Private Sub ButtonAllow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonAllow.Click
  2.         FileSystemWatcher1.EnableRaisingEvents = False
  3.  
  4.     End Sub
And lastly, for disallowing files and folders to be created put this code in your disallowed button.
  1.     Private Sub Buttondontallow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Buttondontallow.Click
  2.  
  3.         If Not TextBox1.Text = Nothing Then
  4.             FileSystemWatcher1.Path = TextBox1.Text
  5.             FileSystemWatcher1.EnableRaisingEvents = True
  6.             FileSystemWatcher1.IncludeSubdirectories = True
  7.         Else
  8.             MessageBox.Show("Please enter the path, you wish to monitor")
  9.         End If
  10.     End Sub
