Capturing And Using Keypress Events

I am trying to modifying the "Math Quiz" tutorial to be more user friendly.

The initial tutorial does not consider the users efforts to answer the math problems as quickly as possible.

The problem is that you must use the mouse or tab key rather than the "enter" key to move to the next control after answering. I believe using the "Enter key to be much more intuitive.

Therefore, I wish to modify the program to either:

1. Check the KeyPress event of the NumberUpDown controls to watch for the "Enter" key to be pressed, and if it is, check to ensure that the current NumberUpDown control is not empty (= Nothing) and if both are True, to then TAB to the next control in the TAB order; OR

2. Uses the PreviewKeyDown event to transpose the "Enter" into a "Tab" automatically so the application will then TAB to the next control in the TAB order.

With all of the new changes to VB 2010 from the last version I actually used professionally (VB6), things are REALLY different, so I no longer know how to accomplish this same task in the new manner. especially if it contains working CODE, because I have always learned better the first time from an example. here is my version of the tutorial Code:

'--- Create a Random object to generate random numbers.
Private objRandomValue As New Random
'--- The Integers will store the numbers for the
' addition problem.
