I think the keyboard ia automatically shown when you click in an edit field. Why not try a simple application to test it? Or look in the MSDN documentation.

Rather simple to get the On Screen Keyboard to show:

C#

System.Diagnostics.Process.Start("osk.exe");

Now you are going to need to catch the handle reference if you want to close it automatically. I don't know that one off-hand but Social,MSDN does have a thread on it
How can I close on screen keyboard by using C#[^]

What you seek is the TextBox.GotFocus() event

That all depends on what UI you are using; WinForms, WPF, ??

WinForms

Don;t know how it works with the touch UI, but here is the Windows Forms GotFocus documentation- it also contains event order and other info that may be of use.
