VB5, VB6 Create a Label for Automatic Totaling
This class accepts numeric values from other controls and adds them into a total for display.
In turn, the class can pass the value stored in its bound label to another instance of itself.
Because totaling is done at the request of the calling object, the class must back off the
calling object's old value when it updates the total.
