Writing an archive viewer

[finale00]

So I'm using C# to write a simple archive viewer GUI.
I have it working and it loads up my archive and displays all of the file paths in a nice tree view structure.

But I don't have any references to my list of file entries to actually get the offsets and sizes!



Anyone have ideas on how I could reference my entries?

I've done something similar in VGMToolbox, see the source for the ISO Extractor form here. Drop me a PM if you have any questions.

I guess using that tag property is the easiest way to go. I'll go with that for now.

i'm not familiar with c# in any way, but you only need store all the file data in an array(or vector or similar) and have the tree items hold an index so the file data array.

Finale00 great job.
Could you please give me a link to some toturials where to start from ? what you did is just what i wanted to do also in c#.
But i want to learn to do it.

If its not so hard to learn and understand could you give me some guide so i can get at least to the point you did ?

I already knew what I wanted to do so it was a matter of looking at how to write it in C#.

1: you start by figuring out the archive format
2: then you write an unpacker script (to verify the format is correct)
3: then you make the GUI and have it run the unpacker script (you might re-write the script in C# if you didn't already)
4: the unpacker script doesn't actually unpack anything in GUI mode; instead, it parses it and returns a list of file entries, which you can draw on the GUI
5: users then choose what to unpack: everything, selected items, selected folders, etc.

Everything I needed was on stackoverflow and microsoft's online docs.

Or you could skip having to write a GUI and just write a MexScript.

Usually I would expect an unpacker eventually becomes a re-packer, and support specific functionality for the particular format.

MultiEx Commander allows for repacking archives, though I don't understand very well how it decides whether it can or can't repack a given archive format (and I definitely have no comment on format-specific functionality).
