Show/Hide On Screen Keyboard (OSK, Touchscreen)

I want to show and hide the OSK keyboard (docked at the bottom) for my touch screen application best methods? (I want to make sure when I show that I try to run, in case someone closed it while using the app)

make a button or menu strip as u wish and call it what u wish
and use this code

Code:

---

Shell("cmd.exe /c start osk")

---

Works like charm

What about hiding the OSK?

The user will close it or minimize it

Simplest.
Use process to get the id of the osk and close it.

As always, you should use Process.Start in preference to Shell. We're using VB.NET now so let's use VB.NET.

vb.net Code:

Public Class Form1
 
    Private oskProcess As Process
 
    Private Sub openButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles openButton.Click
        If Me.oskProcess Is Nothing OrElse Me.oskProcess.HasExited Then
            If Me.oskProcess IsNot Nothing AndAlso Me.oskProcess.HasExited Then
                Me.oskProcess.Close()
            End If
 
            Me.oskProcess = Process.Start("osk")
        End If
    End Sub
 
    Private Sub closeButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles closeButton.Click
        If Me.oskProcess IsNot Nothing Then
            If Not Me.oskProcess.HasExited Then
                'CloseMainWindow would generally be preferred but the OSK doesn't respond.
                Me.oskProcess.Kill()
            End If
 
            Me.oskProcess.Close()
            Me.oskProcess = Nothing
        End If
    End Sub
 
End Class

Mine Opens, but does not close. I don't actually need to close it, I could minimize it or something too. I also realize now that the OSK isn't the same keyboard used in the Tablet PC input panel. The one in the Tablet PC input panel is better :-/

the tablet OSK is:
Me.oskProcess = Process.Start("C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe")
