sorry.  I should have not included ASP.NET.  This is a .NET desktop app.

Or what if I create my own little form which is a "keypad", and do a Sendkeys?   The problem I am running into is that Sendkeys send to the active window, so how do I click a button on my form with the form getting focus?

You just need to create a simple for for that (like this http://www.codeproject.com/Articles/267588/Creating-a-touchscreen-interface-such-as-a-numeric)

You could remove the focus and use do something like this (using RegisterHotKey):

I have a simple form working.  I can use SendKeys to enter data to the active window, like Wordpad or Excel or Word.   I use the code shown below to prevent the form from being "active".

However the point of creating this numeric keypad is to use it within my own app.  But it does not work, in that when I click a button on my keypad form, my app loses focus.  How can I prevent that?  See image.    



 Protected Overrides ReadOnly Property ShowWithoutActivation As Boolean
        Get
            Return True
        End Get
    End Property

    Protected Overrides ReadOnly Property CreateParams As System.Windows.Forms.CreateParams
        Get

            Const WS_EX_NOACTIVATE As Integer = &H8000000
            Dim params As CreateParams = MyBase.CreateParams
            params.ExStyle = params.ExStyle Or WS_EX_NOACTIVATE
            Return params

        End Get
    End Property  

 Private Sub Class1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

       Me.TopMost = True

    End Sub
