Get user input on string, ideally using uicontrol?

So, I've been asked to make a script that determines an ID from the filename of an imported file. For instance, something like RN101_HF_523HFC.xls might lead to an ID of RN101_HF, and I just want to make something like a popup window that asks the user if the string 'RN101_HF' is correct, and allow them to edit it however they'd like. The ideal solution for me would be something like a popup window that has a prompt asking them to confirm the ID, with an editable text field that is already filled in with the ID generated by the code, and a confirmation button.

I have literally no idea how to do this in matlab, but I've seen that uicontrol might be able to do something like this? I can't seem to find any helpful guides on using uicontrol though from what I've seen.

See https://www.mathworks.com/help/matlab/ref/inputdlg.html and in particular the default input option.

[filename, pathname] = uigetfile('*.xls', 'Choose file');
if ~ischar(filename); return; end   %user cancel
ID = regexp(filename, '^[^_]+_[^_.]+', 'match');
if isempty(ID); [~, ID, ~] = fileparts(filename); end  %case in which the ID is wrong form to guess

Now call inputdlg using ID as the default input.

Thanks man. I haven't looked closely at your code, as I'd already set that part up (I was just trying to do the dialog box part). The inputdlg function was exactly what I was looking for though! Pretty much exactly the default code did exactly what I wanted it to.

Btw, I've now got another question regarding the easiest way to setup a checkbox dialog box? Pretty much, I want exactly what inputdlg does, but with checkboxes instead of edit text fields. I'm about to post another question for this purpose.
