Capture Function Keys in VB.NET Windows Application

The following snippet might help you in capturing the Function Keys (F1 to F12) in a VB.NET application

VB

Private Sub frmWinSamAppMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        ' -- Sample Code for http://DotNetDud.BlogSpot.com
        Select Case e.KeyCode
            Case Keys.F1
                MessageBox.Show("Help is on the way")
            Case Keys.F5
                RefreshMethod()
            Case Keys.F9
                MessageBox.Show("You have pressed F9")
        End Select

Please read the documentation at the link given in the solution.
When the user presses the F1 key HelpRequested event will be raised, in which the help can be handled.
