How can I hide the little keyboard popup in Windows Mobile 6.5? (c#)

Question

I have an app that is essentially a wizard that goes through some dialog boxes. One of the forms has just a button on it that brings up the common \"take picture\" dialog.

This answer was taken from the following article http://beemobile4.net/support/technical-articles/windows-mobile-programming-tricks-on-net-compact-framework-12 (I have only added the using statements). I'm on Windows Mobile 6.1 Classic, .NET CF 3.5.

using System;
using System.Runtime.InteropServices;

[DllImport("coredll.dll", SetLastError = true)]
private static extern IntPtr FindWindow(string caption, string className);

[DllImport("coredll.dll", SetLastError = true)]
private static extern bool ShowWindow(IntPtr hwnd, int state);

[DllImport("coredll.dll")]
private static extern IntPtr GetWindow(IntPtr hWnd, uint uCmd);

private const int SW_HIDE = 0;
private const int SW_SHOW = 1;
private const int GW_CHILD = 5;

///         
/// Shows the SIP (Software Input Panel) button.        
///
static public void ShowHideSIP(int nShowOrHide)
{
    IntPtr hSipWindow = FindWindow("MS_SIPBUTTON", "MS_SIPBUTTON");
    if (hSipWindow != IntPtr.Zero)
    {
        IntPtr hSipButton = GetWindow(hSipWindow, GW_CHILD);
        if (hSipButton != IntPtr.Zero)
        {
            bool res = ShowWindow(hSipButton, nShowOrHide);
        }
    }
}
