I want to create a listbox and the content of the listbox has to be an array (yourcell),

This array will be the filenames inside sFiles.

I have this code:

for i=1:1:length(sFiles)
yourcell={sFiles(i).FileName};
res=uicontrol('Style', 'listbox','Position',[50 200 1000 200],...
    'string',yourcell,'max',10,'min',1);
end

Does anybody has an idea why it's not working?

Thanks

You create the listbox inside a loop. That means every loop iteration, you make a listbox on your selected position with only the i'th index of filename. You need to set up your entire list of items first (e.g. inside the loop), then create your listbox after the loop. For example:

yourcell={sFiles(1).FileName};
for i=2:1:length(sFiles)
yourcell=[yourcell,{sFiles(i).FileName}];
end
res=uicontrol('Style', 'listbox','Position',[50 200 1000 200],...
    'string',yourcell,'max',10,'min',1);
