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.. ^^

my above example deletes the content and adds new one. iam not sure what you want exactly.

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 = [];
