Lock the keyboard

[Hugh Janus]

Hi all,

There are hundreds of posts on usenet to do something similar to what I
want but either they do not work or are no good for me. Here is my
problem:

I have a form which covers the entire window. Therefore the start
button is not available for clicking. However, you can activate the
button using the windows key on the keyboard. What I want to do is
entirely lock the keyboard so that any input is ignored until i say so.

I tried trapping the event with the below code but it is just ignored,
consequently the user can open the start menu.

Private Sub Form1Trap_KeyDo wn(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyEventA rgs) Handles MyBase.KeyDown

If e.KeyCode = Keys.LWin Then

SendKeys.Send(" {TAB}")
Application.DoE vents()

ElseIf e.KeyCode = Keys.RWin Then

Application.DoE vents()

End If

End Sub

It may well be that my code is wrong or that I am doing something
wrong. I known that there is the BlockInput command but that blocks
the mouse as well whereas I need the user to use the mouse to interact
with the form.

Any ideas on how to block the keyboard until I say not to? I am using
VB.NET 2003. I don't mind if it is not managed code (as I suspect that
it won't be).

Thanks,
Hugh
