I have created a simple form that inserts/updates/deletes a values for Northwind Customers.
Everything works fine, except in order to see a results, I have to close it, and reopen again.
My form looks like this :

I’ve searched tens of articles on how to refresh ListBox, but all of those use interface implementing, or using DataSets, and stuff I have never heard of and cannot implement. It’s a very simple project, using simple procedures. Is there an easy way to refresh the list of customers without adding many lines of code?

    How about calling ListBox.UpdateLayout?

    Of course you also need to update the particular item(s) so that it returns the updated string from the ToString method.

    UPDATE: I think you also need to call ListBox.InvalidateArrange before you call ListBox.UpdateLayout.
