Hey guys
I am not a J# guy at all but made the unfortunate mistake of using the J# zip classes in a .NET app of mine  The app takes a zip file, strips off certain filtered files and writes a new zip file. The issue is that this new zip file is somehow slightly corrupted. I can't read the app-written zip using my app, but WinZip reads it correctly and can extract it correctly too; but even WinZip cannot do a direct delete of an entry (from within WinZip) - it shows some header corrupt error. I am not sure whether the issue is with the ZipFile constructor (while reading) or with the ZipOutputStream class (while writing).
Google searches tell me that this is a known bug and a Microsoft person's suggested workaround was to extract all files with WinZip and rezip it using WinZip. I almost choked with horror at the very idea that this was even remotely a workaround  Gosh! I mean if I could do that using WinZip, then why use these zip classes at all, eh?
Anyway I just wanted to know if there is any hotfix or patch that's ready for fixing this bug? Thanks in advance for any help.

Not that I'm aware of but I do have some alternatives for zip libraries.
I've used this one before and it works well.
http://www.icsharpcode.net/OpenSource/SharpZipLib/Default.aspx[^]
I think there is also a paid alternative from XCeed soft
http://www.xceedsoft.com/products/ZipCompL/index.htm[^]
I somehow dont like hotfixes (for obvious reasons it needs to be sent along with your app and made sure that all the clients install it), which is a major pain.
Anyway, I'm very curious why did you even think of J#, you know that you need a redistributable thingy when you touch it.
Regards,
Kannan

Yup - that's what I am using now. It doesn't work as well as I want it to - but it's fine for my current purposes

This app is for me - to help me when I am editing. I don't intend to distribute it - though maybe I could upload it to the CP tools section for the other editors. It's too simple an app though Just removes unwanted/disallowed files from the zip.

Its based on the zlib impl. so i'm sure its not very friendly in terms of API usability, but its free
As far the paid part I happened to use that in one of my projects when .net was on its initial stage and I think sharpzip was just on its initialstage or was not stable(i dont remember now).
Anyway, didn't know that you are using it for your personal stuff
I'm now having a horrible time with the vs.net ide with some huge no. of projects, it just sucks  :
you seemed to have cleaned up most of the stuff from your page, I guess the left overs would be difficult to erase, offcourse you can ask the CP God

BTW what makes me mad is that there is not even a KB article describing the bug in the zip class library

The .NET FCL 2.0 will include compression streams (at least it does now). Just FYI.

Thanks for the info Heath. I am writing a bug-report-article for CP to save others the trouble I went through  And I've mentioned this there.

Hey thats cool, where did you get that info from, I haven't seen this one mentioned anywhere. Any idea if this stuff is in the March CTP drop.

Because I have the PDC bits of .NET 2.0 and VS.NET 2005 (being an MSDN subscriber).

I made a small bzip2 Managed C++ lib, here on CP. Simple, easy
|
|
|
|

That's cool leppie I didn't know about it, else might well have used that one instead. Now I am using SharpZipLib now - the class/method names are compatible with the buggy J# library classes.
BTW I presume you just wrote a wrapper, right? SharpZipLib seems to be fully managed code

I've got a Form that I created that has roughly 30 controls that I need to tab through. I set the Tab Index of each control accordingly, but the tab NEVER follows this order. I'm not doing anything fancy to the controls such as handling events. It almost looks like the form is tabbing through the controls in the order which I added them to the form. On a hunch, I even tried rearranging the initialization in the Component Designer Generated code so that they even appeared in the code in the correct order, but this still didn't help. Has anybody else ever had this problem? How can I take care of it? Would appreciate the help! Thanks

Set the tabindex AFTER you have added the tab page to the tab control
|
|
|
|
|
no no, it's not a tab control. It is a bunch of text and combo boxes that refuse to tab in the order I set the TabIndexes. Sorry for the confusion.
|
|
|
|
|
In Visual Studio .NET, use the View TabOrder menu item to set these. This should also change the order in which the controls are added using the AddRange method of their container control's Controls collection property.

I'm writing an application at the time, an MP3 player (using DX9's AudioVideoPlayback class). I've got it fairly full-featured: ID3v1 and v2 tag reading, writing will come in the future (I use UltraID3Lib for this); playlists; shuffle and repeat, etc.
I've got two small problems though:
My first one is that whenever I try to set the Volume property of the DirectX.AudioVideoPlayback.Audio class, it throws an error. Anyone know why?
My second invovles the playlist: it's a regular listbox, which I simply feed with filenames (with full paths, so that the audio class can know what to open) - I would like to be able to display ID3 tags here though - I was wondering if anyone knew an easy way for me to display ID3 tags, but have a hidden field of some sort that holds the path for that particular item. I don't know if I could maybe do this with a listView or not, but if anyone knows, please let me know. If it has to be done using owner drawn controls, I would really appreciate if someone wrote the code, they would receive full credit for it.
Thanks in advance.

Have a look at my nBass article. It has a small class for v1, v2 OTOH is rather complicated.

I tried using nBass..It really never worked for me. No matter what, I couldn't get files to play...DX9 works fine for now.
About the error, I'll get back to you about it as soon as I reproduce it. I'm writing this right before I get ready for a shower and some well-deserved rest, so that'll most likely be tomorrow. (I know, I should've posted it, but my mind slipped)

Why don't you tell us what error you get? Do you simply tell a doctor that you have a pain without saying where? How do you expect us to help you if you don't even say what exactly is wrong? There could be many reasons you're having problems. An exception type and message would definitely help.

Hi,
I noticed in an app sample that it uses an CustomersDataset.xsd file to create its datasets from it. Now in this xsd file is like a customers table with elements in it and also another table with the name of the xsd file as it's title with a ref=customers. This table is linked to another customers table. So there is two of the same customers tables in this xsd but only one is linked to the table with the ref. What is happening inside this xsd file. I noticed in code also that a procedures signature is defined as "CustomersDataset GetCustData()". That's it no public or private in front. How come this isn't throwing an error?
Thanks,
JJ

You will have to read up on how XML Schema works (have some headache pills handy).

WHy should it be throwing an error? type members by default are private , while namespace members are internal by default.

Hi,
I have a problem with creating a diffgram dataset. My connection to database is limited so when I'm not connected to database I need to create a diffgram dataset. But if I'm disconnected how can I get the scheme source for the dataset? I guess I need this in order to create a diffgram dataset. How should I approach this issue?
Thanks,
JJ
