Required :- A simple piece of code to list the files in a dir and return the select file name as a string.

Hi All

As stated in my question I am after what I imaging is a commonly required and hopefully simple piece of code to provide a drop down list of files in a directory. The selected file name would then be returned so the contents can be processed.

Would be much obliged if anyone can point me to an example.

Many thanks

Tom

Do you need a drop-down list for any reasons, or does UIGETFILE matchs your needs already?

This is exactly the dialog users are expecting.

As Sean suggests, uigetfile provides a standard file selection dialog box. Otherwise, you can also use dir or ls to get a file listing of a directory.

For example:

fls = cellstr(ls('*.m'))
k = menu('Pick your file',fls)
filetodostuffwith = fls{k}

Or listdlg:

listdlg('ListString',fls)

If is really must be a drop-down list - but I'd prefer Sean's suggestion:

DirList  = dir(Folder);
FileList = {DirList.name};
FileList(strncmpi(FileList, '.', 1)) = [];  % neither . nor ..
uicontrol('Style', 'popupmenu', 'String', FileList, ...
          'Callback', @mySelect);

function mySelect(ObjH, EventData)
Value  = get(ObjH, 'Value');
String = get(ObjH, 'String');
disp(String{Value});
