how to keep running a "checking file function

[cheekangteh]

i face a problem in checking file condition.
I wish to create a program that can check the condition file continuously while the program is running.

For code below that I wrote:

Private Sub StartTracking_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FILE_NAME As String = "\Program Files\Fast_Automatic_Accident_Notification_Through_SMS\Resources\contact4.txt"
 
        If System.IO.File.Exists(FILE_NAME) = True Then
 
            MessageBox.Show("File already Exist")
 
                    ElseIf MessageBox.Show("File not Exist") Then
 
        End If
 
End Sub

It just can check the file condition only once, that this is only the program first load.

If I suddenly remove the file, it can’t show a message “ File not Exist” or if I suddenly receive a file and place at the folder, it can’t show me a message “File already Exist”

Kindly advice, How can I modify my code to continuously checking the file condition while the program is running.

thanks a lot.

I would start with the FileSystemWatch er, which is designed to do the task you're trying to do.
