hello sir,
Thank you sir.your explaination is perfect sir.i am trying according to the steps given sir.now i want to define 6 functions to control 6 operations in a system.so sir could you tell me depending on factor of touch screen ,we should divide (x,y) values .so that 6 functions are to be controlled through touch screen……….likewise ex: if we take keypad we had 0 to 9 digits.so 9 functions can be controlled on selecting the digits.the same logic has to be implemented using touch screen.how sir?can you tell me.
