How can I populate a listbox with all doc files in a selected folder using a button in App designer?

function selectDocButtonPushed(app, event)        
app.selectedPath = uigetdir();        
docFileInfo = dir('*.doc')         
app.docListBox.Items = docFileInfo.name    
end

Give this a shot,

docFileInfo = dir(fullfile(app.selectedPath, '*.doc'));
app.docListBox.Items =  {docFileInfo.name}';

Thank a lot. I meant how can I store the one file which is marked/selected in the listbox?

Here's what you need to know about the listbox.

1) app.ListBox.Items stores what you seein the list.

2) app.ListBox.ItemsData is used to store optiona info about each item in the list. This is what is returned when you fetch the currently selected item.

3) app.ListBox.Value returns the currently selected ItemsData.

So, what I recommend is to store the file names in Items and the full paths in ItemsData. Then, to get the full path of the selected item, you just need to access the Value property.
