Thank you Friedrich ^^, I have tried your code.. but it doesn't work like i want... :( it just remove temporary... I have tried use:
hListBOx = [];
it can remove all, but i can't input the other string :( .. So, i want to remove all, but i can input other string too... Thank you before.. ^^

I believe both of the other answers are wrong. They will totally delete/remove the listbox, which I don't think is what was wanted. I think the original poster simply wanted to clear out the contents of the listbox.
To do that you don't set the handle of the listbox to null,
hListBOx = []; % Deletes listbox.
you set the String property of the listbox to null
hListbox.String = []; % Clears contents of listbox but leaves an empty listbox on the GUI.
Using GUIDE with a Listbox with tag lstFileList (or whatever you have):
handles.lstFileList.String = [];
or in App Designer:
app.lstFileList.String = [];
