In Windows Mobile, call the input method and change the position of the Input Panel.

Write full screen applications Program To make full use of the screen space, cancel the input method panel. But there is no input method panel. How do I set the display position of the Input Panel? One feasible method is to call P/invoke and call the input method in the program. The interface is as follows:

CodeAs follows:

Using System;
Using System. componentmodel;
Using System. drawing;
Using System. Windows. forms;
Using System. runtime. interopservices;
