Remarks
On Windows CE–based devices that use a stylus and touch screen instead of a mouse, the ptmember contains the coordinates of the last position touched on the screen, rather than the coordinates of the current cursor position.
If you need mouse cursor support in your application, use the Windows CE Iconcurs component rather than the Windows CE Icon component and the Windows CE Mcursor component rather than the Windows CE Cursor component.
The timemember is the number of milliseconds since a cold or warm boot on a device. It is the value returned by the GetTickCountfunction. Not included is the time that a device is in suspend mode.
