Hi, I have a Listbox that i display in an application. When i double-click on an item in the list a form is shown with more detailed information. So far so good but the problem is that there is some old rubbish left from the listbox in the background of the screen when i display my form so it is hard to read cause everything is blurred.

My Question is, is there any way to get rid of the old listbox before i display my form? If someone knows howto do this please send me an answer as soon as possible!
