Display .mp3 names in GUI.CreateTextboxChoice

What is it you are trying to achieve?
<Importing Sound files and displaying their names in GUI>


What is the problem you are having?
<Confusion inside of my brain.>


Describe what you have tried to solve this problem
<Attempting to read help files, didn't help>

Please specify what version of Turing you are using
<4.0.5>


I'm doing a final project, my intentions are to use a GUI.CreateTextBoxChoice to display a list of songs that are placed in the program's saved location. So somebody puts a song with the filename "Xsong.mp3", and in the GUI's scroll list shows a file called "Xsong.mp3". Clicking the song plays it, all songs will be of same format so that they cancel each other.

I could probably figure out how to make people pick from a selection of songs, but I would like it so that the user can use their own songs. I just need to know if it's possible in Turing to do this.

If you don't think it would work with GUI.CreateTextBoxChoice (Because I myself have doubts), please say how I could get this to work. GUI was one of the few things we didn't learn how to do, so that's why I'm asking here

Thanks

What you could do is keep a text file that contains the names and paths to all the songs. When you run the program, read in all the songs from this file. If the user wants to add a song, have the program add it to the file.

I see... that makes sense.

I'm assuming... when you first run the program it checks the directory for .mp3 files (Not sure how you would go about doing that), then saves the names into a text file that can be read later...

This just got more confusing now

I think he means that you manually create the txt file, but the program adds the filename youve entered to the txt file. Scanning the folder for .mp3 files is pretty advanced, so I suggest you drop the file scanning and use this basic outline:

- read .txt: .mp3 filenames
- add or play?
- if add, get new filename
-- add to .txt file
- if play, use the textBoxChoice setup

The dirmodule likely has something that can help read file names in a directory.

You have all been helpful.

Here is what I have right now, it works but I need some advice, or something. (I'm sure there's a lot of useless lines in there, a result of experimenting)

code:

setscreen ("graphics:1000;1000")
var addsongnum, fileNo : int
var x : int := 0
var adder : array 1 .. 9999 of string
open : fileNo, "songnames", get
assert fileNo > 0
loop
    exit when eof (fileNo)

    get : fileNo, adder (x + 1)
    x := x + 1
end loop
close : fileNo
var playsongname : string
var streamNumber, file : int
var fileName : string
streamNumber := Dir.Open (".")
assert streamNumber > 0
open : fileNo, "songnames", put
loop
    fileName := Dir.Get (streamNumber)
    exit when fileName = ""
    put : fileNo, fileName
end loop
Dir.Close (streamNumber)
put "These are the optional songs to play that you have imported!"
for w : 3 .. (x - 3)
    % if adder (w) *  "3" then
        put adder (w)
    % else
    % end if
end for
put ""
put "What song would you like to play?"
get playsongname
process playmusic
    loop
        Music.PlayFile (playsongname)
    end loop
end playmusic
fork playmusic




(Put sound file in same directory as saved example then just run)

How would I go about having an if statement, that would use string manipulation to determine if a line in the text file it reads ends with .mp3?

I have it so that it reads from the text file and (used to) skip a few items that weren't songs (hence the for loop "w" starting at 3 and going to x-3). Now with a ton of songs it doesn't skip them properly, so I'll have to use an if statement or something to only show them on the screen if it ends in .mp3, or at least a 3 using an *.

you can select just a part of a string. substring

But how would I even use that in an if statement?

code:

for w : 3 .. (x)
     if adder (w) (*..*-2) = "mp3" then
        put adder (w)
     else
     end if
end for

* being last, *-2 being the last three, equaling "mp3", sounds like it works, just doesn't. I don't know how to do this properly.

Edit: Durr, put the things backwards. Still doesn't work though.

what is it actually though?
code:

if adder (w) (*..*-2) = "mp3" then
        put adder (w)
     else
        put "not mp3. Found: ", adder (w) (*..*-2)
     end if

     end if


I scan the directory and save all of the files onto a text file. Then I open the text file and display all of the objects on the screen, allowing the user to see the choices they can select.

This part right here is the "put" part, "adder" is an array, "adder(1)" is line 1 in the text file, "adder(2)" is line 2 etc.

So instead of putting every line (Which includes the program's name itself, the text file's name etc.), I'm trying to get it to only put files that end in "mp3" on the screen.

That "Not MP3" part works I guess, but it would be nice to just not show them at all

The "not mp3" line is just a placeholder for understanding what your program is actually doing.

I spent some more time on it today and got it working 100% perfectly, I am happy.

Thanks for the help everybody, the Dir module really helped. Even my teacher didn't know what it was lol
