I have a program Im making for school, using the "Marine biology" casestudy as a guide(reference, More like i have never looked at it and made my aquarium in 3d while everyone''s elses is a 2d matrix), and i just want mine to be 200% better then all the others in my class, How can i get(retrieve) all the file names in a folder. Like pass a function a directory(apstring) and it returns a vector(apvector) containing strings(APSTRINGS) of all the files in that directory.

I mostly have rewritten the entire class structure to be easier for my extreme changes. Apvector and matrix and apstring were changed to include "windows.h" so they give errors in popups instead of couts, since im not using a console.

The Structure of it is like this(Sorta)
Notes*
The simulation class and neigbor class were combined with environment and plot. Instead of 1 fish perblock i allow for 10(Look for squares with 2 or 3 fish stacked on each other).
They can only eat, breed things in their same square.

Theyre are 3 images of what i have made so far at.

I might, I think it would be over 800K with all the resource files (Textures, 3D Modles)

And how are those functions used to return file names?

Is theyre an example i can use, im still new to the windows things.

Thanks, now i can make a neat user interface to select the environment to load.
