How to implement your FileSystemWatcher

How to implement your FileSystemWatcher

Step 1

Once you have created your FileSystemWatcher, you need to set certain parameters for it.

Step 2

We will do this in the Form_Load event. What we are trying to do is to create a FileSystemWatcher event that will detect creation of file with the extension TXT to it’s directory only – not inclusive of subdirectories. This is all configuring with the codes below.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

FileSystemWatcher1.Path = "c:\im"

FileSystemWatcher1.Filter = "*.txt"

FileSystemWatcher1.IncludeSubdirectories = False

FileSystemWatcher1.EnableRaisingEvents = True

End Sub

Step 3

Then to implement our FILE CREATION event,

Step 4

Go to your FileSytemWatcher1 object and then select it’s events under Declaration in the Created

Step 5

Under this control, use the MsgBox to notify user that a TXT file has been created in your folder called IM.

Private Sub FileSystemWatcher1_Created(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created

MsgBox("A newly created TXT file is detected")

End Sub
