I'm working on a program. It watches a folder for file changes. in certain cases, it needs delete the files in that folder. sometimes, it has this error:
The action can't be completed because the file is open in another program
is there a way to force delete a file? or this is not possible?
How can be find out which file is going to delete when, user provides command like DELETE or SHIFT + DELETE or by programmatically gives DELETE command. Well I know about FileSystemWatcher Class, but this class doesn't provide information before delete...

The current code works fine on the very first fresh but after that it doesn't remember what node was clicked. For this refresh I am looking for a ini file and if found I delete the ini file and refresh the tree. The tree has only 2 parents and never anymore then that.
This first part is the timer sub
Private Sub Timer2_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Dim SelectNode As String = Me.tvFolders.SelectedNode.Name
Try
' check to see if file exist, if so do refresh then delete file
If (File.Exists(appPath & "refresh.ini")) Then
File.Delete(appPath & "refresh.ini")
[Code] .....
Now the main problem is if you click on a child in parent2 and hit refresh it is not sending Parent2 as a treenode to the search function and it doesn't remember the node clicked. But if you click on a child in parent1 it remembers the node but always refreshes to the top parent1 node. but the very first time you refresh in parent1 it works perfect. Even on the second refresh regardless of which parent you are in it never comes back with failed message from the search function.
