A Touch Screen and Stylus are one of the ways that a user can interact with a Windows CE-based device. A touch screen usually needs to be calibrated before it can be used the first time. Calibration ensures that the coordinates of the area touched by the stylus on the touch screen are close to the coordinates of the display. Windows CE has a default user interface for calibrating the Touch Screen, and it is called Calibrui. Calibrui module controls the appearance of the touch screen calibration window. User calibration is necessary because of the physical nature of touch screen hardware. For example, on the Handheld PC (H/PC), a user is prompted to tap the stylus at various points, indicated by a cross-hair cursor, on the screen before the target device is ready for first use.

If your application has a dramatically different touch screen display size or orientation, you can replace the default Calibrui module with a user interface that is more appropriate for the target device.

This how-to shows the steps that are necessary for you to replace the Calibrui module.
