Question

ICSharpCode.SharpZipLib.BZip2 - Datasets

Asked by: flavo

I have a modelling package, that until recently, used text files for data input / output. This was great as I could use Excel / VBA to automate various model runs for sensitivity testing and the like.

Now they've come out with a new version of the software and kissed those text files goodbye.

After some digging, I've managed to find that the file seems to be a dataset compressed using ICSharpCode.SharpZipLib.BZip2 { http://www.icsharpcode.net/OpenSource/SharpZipLib/ }.

I've tried to use a few samples but end up getting totally lost - seems as though this is a little out of my league (haven't touched .Net for well over a year now).

I've tried to play with the minibzip2 sample {found at link above} with now luck.

I'll upload the files I'm talking about to eestuff once I've posted this.

Hopefully I don't need to be hand feed...

I'm comfortable enough with both C# and VB .Net

Thanks,

Dave

The aap file is the one I'm talking about, and the text file is what I believe the file looks like uncompressed.

Dave,

This is how I uncompress the file:

        private void Form1_Load(object sender, EventArgs e)
        {
            this.Decompress(@"C:\downloads\sid.aap", @"C:\temp\sid.xml");
        }

        private void Decompress(string inFileName, string outFileName)
        {
            using (FileStream inStream = new FileStream(inFileName, FileMode.Open))
            using (FileStream outStream = new FileStream(outFileName, FileMode.Create))
                BZip2.Decompress(inStream, outStream);
        }

Here is the output file, but it has some extra stuff in there:

Thanks, Bob.

I think I was trying to be a little too tricky for my own good. I've been able to edit the extracted textfile by hand, compress it and seems to run Ok.

Now I just need to code up the manual changing.

Thanks,

Dave
