Question

I was trying to make a file unlocker which get process which using the file and get it killed to make it able to be deleted. It was okay when my targeted file is a WMP file. But I can’t get it work when it comes to dll and iso. I got the problem on this line:

Which is used to get the process name. Any help is appreciated.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnShow.Click
  Dim files As New List(Of String)
  files.Add(OpenFileDialog1.FileName)
  Dim Processes As List(Of Process) = Util.GetProcessesUsingFiles(files)
  RichTextBox1.AppendText(vbCrLf & "Processes that using the file is:")
  For Each p As Process In Processes
    TextBox1.Text = (Path.GetFileName(p.MainModule.FileName))
    TextBox1.Text = TextBox1.Text.Replace(".exe", "")
  Next
  Timer1.Start()
End Sub
  Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnKill.Click
    If TextBox1.Text = ("Nothing") Then
        MsgBox("No proccess is using that file.")
    ElseIf MsgBox("Proccess(es) killed") Then
    End If
    For Each p As Process In System.Diagnostics.Process.GetProcessesByName(Path.GetFileName(TextBox1.Text))



        Try
            p.Kill()
            ' possibly with a timeout
            p.WaitForExit()
            ' process was terminating or can't be terminated - deal with it
        Catch winException As Win32Exception
            ' process has already exited - might be able to let this one go
        Catch invalidException As InvalidOperationException
        End Try
    Next

I’ve already got the solution. Just add Try..Catch..
