Wilson,

I really don't know enough about the complexity of the UI you are trying to develop. A good way of dealing with this is to have the currently active control "register" with your input control in it's GotFocus() and then you can directly manipulate it's .Value property from your input control. You can test the type() of the .Value to see whether it's numeric or character and behave appropriately.

>I know your solution should solve the problem. But do you think it is hard to use for complex screen which are many objects on the screen. Each objects should tell the keypad it is the current object and waht type of value it stores.
