Hello all,
I have a GUI system that should select a text file from a directory,open it and read it in a code.. I have this code for that( the part of getting the text file):
function FindCallback(source,eventdata)
[FileName,PathName]= uigetfile('*.txt','browse')
s={};
fid = fopen('*.txt');
tline = fgetl(fid);
while ischar(tline)
s=[s;tline];
tline = fgetl(fid);
end
it shows me an error:
Invalid file identifier. Use fopen to generate a valid file
identifier.
Error in ==> GUI_oo>FindCallback at 77
tline = fgetl(fid);
??? Error while evaluating uicontrol Callback
any advice..
Thanks

Instead of fid = fopen('*.txt') use ;
file=fullfile(PathName,FileName)
fid = fopen(file);
