sendmessage and contextmenu in PocketPC

Question

hi, I had been trying to solve the above 2 problems but was unable to find a solution to it. hope that someone could help me. 1) does the pocketpc had the sendmessage function using c#? 2) I needed a tap and hold function for my program so I implemented the context menu for the buttons dynamically. Even though when the user tap and hold on a particular button, my program is able to display the menu correctly but I am unable to detect which button the user actually tap and hold on to. thanks
