Enabling/Disabling Touch Pointer

The touch pointer is the Windows floating graphic that looks like a mouse on
screen. This pointer helps you target small objects since touching small targets is not
accurate for a finger. To show the touch pointer when touching the screen, click
Control Panel > Pen and Input Devices > Touch tab > Make sure Show the touch
pointer when I'm interacting with items on the screen. Click Apply.
If you need to disable and/or enable the touch pointer in your code, you can
intercept operating system window messages using a window procedure
(WndProc) and modify the Windows messages. The C# pseudo-code below shows
how to enable and disable the touch pointer:
const int WM_TABLET_QUERY_SYSTEM_GESTURE_STATUS = 716;
const uint SYSTEM_GESTURE_STATUS_TOUCHUI_FORCEON
const uint SYSTEM_GESTURE_STATUS_TOUCHUI_FORCEOFF = 0x00000200;
protected override void WndProc(ref Message msg)
{
switch (msg.Msg)
{
case WM_TABLET_QUERY_SYSTEM_GESTURE_STATUS:
= 0x00000100;
