For command buttons and option buttons, you could set the caption property with a & sign before the letter with which you need to give the shortcut key for the button.

E.g.

cmdOK button, caption could be "&OK". So that, its shortcut key will be Alt+O for the user.

Similar for the option buttons. Say, if the caption is
"Customer" you could set it like: "C&ustomer", for setting Alt+u as shortcut key.

Put the customer name validation code in the customer name text box validate event. Similarly for other events like:

Private Sub txtCustName_Validate(Cancel As Boolean)
   If Len(txtCustName) = 0 Then
      Msgbox "Invalid Customer Name."
      Cancel = True
   End If
End Sub

Have a form level variable, for calculation, and if the user does the calculation set it to True or else it remain False.

You could check this variable in the cmdOK_Click event, before doing the further processing.

Private Sub cmdOk_Click()
   If mCalculate = False
      Msgbox "Calculation Not Done."
      Exit Sub
   End If
   :
   'your processing code goes here
End Sub

Set your Cancel button(if at all you have)'s CausesValidation property to False, so that the user could be able to cancel the operation without saving and quit out.

Hope this helps,
Cheers.

And, in option groups, to set something to default, set one of the option button's value to true, in design time, or in Form_Load event.
