Keyboard assignments

[Jon Cosby]

I'm trying to assign keys to a textbox. I've added a handler just for that
control. When I hit the keys, though, the values are entered in the active
textbox, not the one they're assigned to. Why is this?

Public Sub New()
MyBase.New()

'This call is required by the Windows Form Designer.
InitializeComponent()

AddHandler tb.KeyPress, AddressOf keypressed
End Sub

Private Sub keypressed(ByVal o As Object, ByVal e As KeyPressEventArgs)
If e.KeyChar = Microsoft.VisualBasic.ChrW(48) Then
e.Handled = True
ElseIf e.KeyChar = Microsoft.VisualBasic.ChrW(49) Then
e.Handled = True
...
tb.Text += e.KeyChar.ToString()
End Sub

I guess that was dumb, but the key assignments only work when the assigned
textbox is the active control. E.g., if I tab to a button, the key values do
not display.
