im trying to write a file manager. its got this:

string[] directories = new string[10000];
directories = System.IO.Directory.GetFiles(path);
for (int i = 0; i <= directories.Length; i++)
  ListView1.Items.Add(directories[i]);

and when i run it, it doesnt populate the list view like it should be doing on the last line. any idea why? thanks.

Try this:

(Toggle Plain Text)

String[] directories = System.IO.Directory.GetFiles(path);
for (int i = 0; i < directories.length; i++)
  ListView1.Items.add(directories[i]);
ListView1.repaint();

Also check your filepath.

This looks more like C#. What's it got to do with VB.NET?

Intimidat0r · Dec 5th, 2005, 11:39 PM

the repaint() method doesn't exist.

and i know the path is correct because ive done things like written directories[] to a file and finding all of the folderes in there.

edit: oh god, im stupid. sorry about that. i wasnt using my brain on that one. of course its c#, im used to posting .net stuff in the vb.net forum. my apologies.

You might also want to consider a dynamically-sized container of some sort, rather than an array. Fixed-sized allocations aren't the best structure for this sort of thing. I'm not sure, but it's quite possible there's already a .NET class designed for storing directory trees; there's also things like the TreeView control which you can populate with the results, depending on how you want to display things. Personally, I like having a hierarchical view in file managers; it's why I replaced the stock one on my PocketPC with a third-party one.

Why are you doing C# if you clearly are a Windows Basher? Why not do C or C++? Answer me that?!!?!?!

Many Linux users use C# with Mono.

Why not use it?

I'm much the same way... I'm not much of a windows basher, but I avoid microsoft products pretty much whenever I can, in my personal life and projects.

However, the industry has a lot of demand for .NET and windows programming right now, and in a lot of places, it's quicker and easier for them to understand and support windows programs, additionally a lot of places 'percieve' that windows is better, and sometimes perception is greater than reality.

Just because you dislike something doesn't mean you cut it out entirely, you use what you need to to get the job done, and please those involved.

lectricpharaoh, ill try using TreeView and also ill look into that class for directory trees.

edit: hmm, still not working...

edit2: never mind i made a mistake. that works, thanks lectricpharaoh and everyone else.
