AppGameKit Classic Chat / GetFirstFolder() seems to get Last folder not the First?

I am finding that using GetFirstFolder() with GetNextFolder() return a list of sub-folders but in reverse order.
Is it meant to work this way, is there a bug or am I missing something.

I have a folder called Alphabet and 26 sub-folders called A through to Z. I was expecting A to be the GetFirstFolder() and Z to be the last from using GetNextFolder() but it lists folders Z to A.



I can reverse the "first through to last" easy enough using an array but feel this should be unnecessary.

Any ideas?

ps using latest version agk2, v 2.0.16 with windows 8.1

I've had exactly this with GetFirstFile. My feeling is that these commands should have an input that allows you to dictate what "first" means - date, name of file, last modified etc

i think it is returning the VTOC order, not sorted order. if you copy the files/folders into the folder in the order in which you want to read them then i think it will work. not a very robust solution though

Hi DavidAGK
Quote: "I've had exactly this with GetFirstFile"

That worried me as I will have a lot more files than folders when I finish and the getting of file/folder order is currently poor. I totally agree with your thoughts about providing these commands with an input to dictate the getting order but I would have at least expected alphabetic order to be mandatory.
I hope Paul gets a chance to view this as this would be a great help.

Have to confess I am not familiar with this terminology but have tried copying in order I want to read but without success, still reverse alphabetical regardless. I don't think it would be very practical for me either, but thanks.

Thank you both for your comments, back to the drawing board unfortunately!

I'm sorry that didn't work (I was sure tht worked for me in my previous project but my mind must be going ). I guess your up for sorting an array.
Not too bad with the V2 array changes: myArray.sort()

@ blink0k, thanks again and yes my only options to date are to use arrays or abandon.
I have found 3 array options that will work, sort, reverse or simply assign my data to each array cell using a bit of maths to reverse the cell numbers. The first 2 methods, and when I say first, I mean sort or reverse array, just in case there is any confusion of which order of methods I refer, both add a small time delay so the last method seems to be the best at the moment.
eg instead of assigning cell numbers by;


This should make cell no 1 = A through to cell no 26 = Z.
(I haven't even started on several hundreds of files yet which will have the same problem).

The biggest problem though for me is if and when we get an update to make the getfirst more logical and default it to alphabetical order. Then it will mean re-writing quite a large chunk as this windows app which is primarily to do with folders and files. Some PJ feedback would be appreciated.
So, do I abandon, postpone or just go back to DBPro where IanM matrix is great?

change to:
for letter = 1 to 26
alphabet[27-letter] = fn$
etc

I keep trying to reply to this post, but haven't quite managed it (until now of course). I just don't get the issue. Does it matter what order those commands return the folders/files? Also, if you know the structure of the folders and files, then surely you don't need to use those commands at all right? I thought they were for when you don't know what files/folders are there.

Its impossible for everyone to guess how someone needs their program to work, so I am not surprised, but if it didn't matter I wouldn't be asking the question in the first place.

The command getfolderfirst() doesn't qualify what criteria it uses to obtain the first folder. I would like to know if getting the order reverse alphabetical is normal, is it an error or what.

My app is for a client who has variable folders, details of which and details of variable sub-folders need to be displayed alphabetically on screen. So yes I know the structure but I also need to use those commands.

Hope that helps with your curiosity.

Anything that will further help with my query would be appreciated.

I have no idea if this would be any faster, but you can insert elements into an array in any position you like. i.e.:

@CJB, that's very impressive and fast, thank you.

I still have the concern though in that" Is getfirstfolder() and getfirstfile() meant to work in reverse alphabetical order or is it an error?". It just seems illogical to work in reverse to me.
If it is correct then I can check the speed of your coding against the speed of mine and employ with confidence the better of the two.
However if the way it works is an error and could be changed shortly to either be corrected and/or for the addition of extra input options as suggested by DavidAGK, then I could do with a time scale to see how long I may have to wait before being able to apply any corrective work if I proceed as is. But I guess only PJ can answer that one.

Thank you again though for your input, appreciated.

It is an oversight on my part, the folders are read in alphabetical order but are placed in a linked list, which reverses the order when they are read back out. I won't change the functionality of the existing command, but I may add an optional parameter to sort the results differently in future.
