View 2 RepliesWeb Browser History - Clear The Listbox When The Form Closes
Feb 26, 2010I have a small script that logs all of the website I visit and then displays them on a form. When I open the form the first time it displays all of the websites like it should. However, the second time I open it, it displays two of every website. The third time opening it, three of every website. I think that it is because the data doesn't get erased from the listbox when I close the form. Is there a way to clear the listbox when the form closes or do I need to find a new way to set it up?

The user also inputs the investment & interest rate. When calculate is clicked the results show in another listbox below.
year 1 $$$$$$
year 2 $$$$$$
