Detect Application Idle - KeyDown not functioning

[Volkof]

Hi all,

I am implementing an idle function whereby if the application has no input for a few seconds, it will refresh the DataGridView table.

To implement, if the app is idle, an IdleTimer will start.
If the user moves mouse or press a key, the IdleTimer will stop, hence resetting the timeout.

Application_Idle works

Private Sub Application_Idle(ByVal sender As Object, ByVal e As EventArgs)
        IdleTimer.Start()
    End Sub

MouseMove works

Private Sub adminViewForm_MouseMove(sender As Object, e As MouseEventArgs) Handles Me.MouseMove
        MessageBox.Show("MouseMove")
        IdleTimer.Stop()
    End Sub

KeyDown does not work. The MessageBox does not appear.

Private Sub adminViewForm_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
        MessageBox.Show("KeyPress")
        IdleTimer.Stop()
    End Sub

Refresh Table

Private Sub IdleTimer_Tick(sender As Object, e As EventArgs) Handles IdleTimer.Tick
        EVC_ProjectsDataSet.Clear()
        ProjectsTableAdapter.Fill(EVC_ProjectsDataSet.Projects)
        save_btn.BackColor = DefaultBackColor
        AddNew_btn.Enabled = True

    End Sub

Any advise is appreciated.
