Your SUB has an error that won't make it work, on this line:
tmpFile = tmpDir + "\DIR$INF0.INF" 'aha!, not a fully pathed file to user directory but here is good!   

The error says: Cannot convert number to string.

Do I need any of Steve's code for this windows temp directory?

QB64 thinks it's a number because we didn't DIM SHARED  tmpDir at start and then set it at start also.
So, you need this clip for starting program, sorry:
Code: QB64: [Select]
  1. DIM SHARED tmpDir AS STRING '  establish a permanent spot for temp files
  2. IF ENVIRON$("TEMP") <> "" THEN 'Thanks to Steve McNeill use user temp files directory
  3.     tmpDir = ENVIRON$("TEMP")
  4. ELSEIF ENVIRON$("TMP") <> "" THEN
  5.     tmpDir = ENVIRON$("TMP")
  6. ELSE 'Thanks to Steve McNeill this should be very unlikely
  7.     IF _DIREXISTS("C:\temp") THEN ELSE MKDIR "C:\temp"
  8.     tmpDir = "C:\temp"
  9.  

ENVIRON$ is a function that returns values for various variables Windows uses for settings and Paths.

Thanks, but we are now back where we started. Maybe you misunderstood me about the problem. Your menu exits out back to my main menu fine. There's no problem with that at all, that I know of. The problem is when after I use your menu, and go back to my main menu and choose "Play Directory", it just sits there, but it also plays the songs. So it DOES go to the playdir section, but for some crazy reason it doesn't CLS and PRINT the sound information that it's playing. Another funny thing is that I can still use the space bar to Pause and P to keep playing, etc., that's in the playdir section. Another strange thing is that if I do not use your code to change the directory and just open the program and choose Play Directory, everything displays fine. So in other words, half of my code is working and the other half is not, on the same section (playdir). Try it out if you want to see what it's doing. But like I said before, no pressure. You mentioned to put whatever I want in that area in the changedir area, I might play around with putting the playdir code inside that and just make 1 section both a change directory and a play directory at the same time. Maybe that will work. I'll try it out. For now, this is what I have. I do appreciate the help. Actually, since your menu exits out fine back to my main menu good, I'm not going to mess with combining them yet.

Edit: I also just added the right temp directory to all the code.

Sounds like a sub is setting _DISPLAY internally, while the program expects _AUTODISPLAY to be in use.

Aha! could be it! but isn't the menu showing OK, but that waits for INPUT... hmm...

I need to get that array display code updated with the Screen State saver sub!

Ken try _AUTODISPLAY in that insert section of changedDirectory GOSUB line 174 and then exit do.

Update: Yep! that fixed it! I just found out I have an MP3 file in QB64 Directory that plays fireworks, maybe you guys do too? It is just as Ken said, info displays fine until run the Change directory code and then nothing shows until there is an input line. And _AUTODISPLAY at line 174 fixed it.

Thanks Steve! saved me some time reworking code.

ROFL WE DID IT!!!!!!!!!!!!!!! LOLOLOL Thanks Steve and B+! I added it right before it RETURN's back to the main menu and it's perfect now. I was almost getting to the point like on the Star Trek II Wrath of Khan when he talks about Kirk (who is this program to me): Khan Noonien Singh: He tasks me. He tasks me, and I shall have him. I'll chase him round the Moons of Nibia and round the Antares Maelstrom and round Perdition's flames before I give him up!

(Edit: I just added one CLS line so it would erase the name of the older song.)

It's too bad we can't use the Windows Default Music Directory with this. I tried adding it just now to my music program just with a couple lines to switch to it, which it did. But I then used the selection to change it again with your folder menu to go deeper to play music in it, but the subscript was out of range. I found out how to switch to it from a Wiki example. I have no idea why it wouldn't work with your folder changer once you are in it. I don't use the Windows Default Music Directory myself but just thought it would be good for people that did.
Here is the Wiki example:
http://www.qb64.org/wiki/DIR$

The subscript is out of range on this line:
 CHDIR myFiles(mySelection&)

Nice find Ken! I did not know of this command.

Try chdir to that directory first in the start of your code, the navigator code has to be in the directory to get more directory info to move around from where it is.

BTW I found a spot in my hard drive that has neither a dot directory nor a .. go up directory, hp is hole navigator can fall into and not be able to get out, no ..

Yes, that's what I did. I made Default Music Directory part of my main menu. So I went there first, then after it changed to the Default Music Directory, it automatically went back to the main menu so then I went to your directory changing selection to go deeper inside of it. When I did it, it showed the deeper folder, and I went to it, but  when I closed it with your X, is when I got that error and the program closed. The error is this:
The subscript is out of range on this line:
 CHDIR myFiles(mySelection&)

The code is very simple to change to the Default Music Directory. It's just this:

Code: QB64: [Select]
  1.  
  2. defaultdir:
  3. CHDIR _DIR$("music")
  4.  
  5.

Hi Ken,

Short on time I just put this line:
CHDIR _DIR$("music") 

Right after, we set tmpDir, and it seems OK to me, a quick test exiting by clicking X. I will test more after supper...

It works fine when you don't click any folders inside your menu. Put a test folder inside of your default music folder and click that. Then click the X and see if you are getting the same error I am.

Did you click the X or press Esc? Pressing Esc seems to work for some odd reason.
This also brings me back to something you offered me to change earlier, which I didn't do. You said to change myFiles to myFolders right? I didn't do it though but I wonder if that makes any difference? The reason I didn't do it is because it was already fixed by the time I saw your advice on the code.
Also, just so you know, the mouse's wheel never worked on the menu, I always have to press the top or bottom to scroll up or down. I don't know if you ever got that working yet.

WOW! I fixed it! LOL! I will test it a couple more times but I think I found the problem. Every computer uses _LIMIT 100 probably a tiny bit differently. I commented out _LIMIT 100 on 2 of yours toward the bottom of your code (and the program). In my experience of working with the _LIMIT command is that when my computers gets around 100, the program slows down dramatically. Sometimes it takes to _LIMIT 50. But this is why I try to not keep it under _LIMIT 200 unless I need something to run very slow. So far I've tested my program and so far it's fixed! Thank you again for the help B+! :)
Now to decide if I want to move my tons of music from its own folder to the Windows Default Music folder lol. I probably should also make that the starting folder of the program as well. I think I will.

Here is my Music Player code that's fixed. I also had to fix the 1 song selection, it had an error when there were no .mp3 files in the directory. So I just changed it to FILES and not FILES *.mp3
I might change that section sometime but as for today, this is my finished version. :)
