Triggers loading of the TaxObject's data.
value = object.Refresh(background)
|object||A TaxControl object|
|value||A numeric result|
|background||boolean true for background read using a separate thread.|
In most situations, tax data will be loaded automatically at run time. However, there may be circumstances which require this data to be reloaded dynamically. Use the refresh method in order to clear the control and reload all tax data. This method would typically be necessary only after changing the DataFilename property. Changes to other properties such as Earnings, FilingStatus, etc., do not require a subsequent Refresh.
