I can't include zip file for example; but I can send it to you directly.

Commented Issue: Unzipping docx throws ObjectDisposedException [30285]

jumbo — Thu, 03 Mar 2011 23:05:34 GMT

I am trying to read document.xml file from docx zip. The code I use to accomplish this is super-easy and is attached as screenshot along with exception detail.
In short: open a ZipFile (using StreamResourceInfo class in WP7) , get a ZipEntry by filename, if ZipEntry is not null - call zipFile.GetInputStream(zipEntry) to get stream, init byte buffer in zipEntry.Size, read stream into buffer <<-- ObjectDisposedException.

Can anyone tell me whether this is bug or I am doing something wrong? Can anyone test it? Thanks!
Comments: ** Comment from web user: jumbo **

I just figured it out. It was my fault! I apologize for this.
The mistake was that I created ZipFile instance twice (two methods, each created its own ZipFile). The second one was not working. When I use only one instance for both methods, it works.

Once again - sorry for confusion,

I just try exactly same process with exactly same code, but with epub (which is zipped too) and it works ok. So I suppose it has something to do with docx format. But I have no idea what can be different/wrong.

Reopened Issue: Issue opening a Zip-Container [28950]

PeterNowak — Fri, 01 Oct 2010 09:31:42 GMT

Hi,

I don't know, if this issue is already known or fixed. I'm working on some Demo-Apps for WP7 and I can't get around a specific issue.
I have a Zip-Container, which has several files in it.
The according Sourcecode snippet is:
IsolatedStorageFileStream isoStream = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("hello.zip",FileMode.Open);
ZipFile zipFile = new ZipFile(isoStream); //Crashes App
Executing this crashes the App in that case, that it hangs and Visual Studio starts get unstable.
The error has been seen with the latest stable version (0.86.0.518).

Is it already fixed in the latest source?
If yes, when to expect a new stable release?

Sorry for bothering,

Cheers, Peter

Not completly working. Just partially.

Hi,

the error is still existing in the latest sourcecode.

Using this sourcecode, the app still crashes:
IsolatedStorageFileStream isoStream = IsolatedStorageFile.GetUserStoreForApplication().OpenFile("hello.zip",FileMode.Open);
IsolatedZipFile zipFile = new IsolatedZipFile(isoStream);

Using the following works instead:
IsolatedZipFile zipFile = new IsolatedZipFile("hello.zip");

Cheers, Peter

Ok, at closer look at your snippet, the problem is clear. ZipFile and FastZip use System.IO file system routines which are not available to SL in the browser or WP7

This is only applicable for OOB SL. I suppose I should simply remove it from the WP7 build.

In the head of the source are beta implementations of ISO versions of ZipFile and FastZip. The Phone7 sample app has simple imlementation example.

After I uninstall WP7 CTP and get RTM up and running I will publish a beta release with these features, but in the meantime, you may want to pull or download the source.

I noticed that assembly is not signed like the SharpZipLib for .NET. Is this intentional?
Thank you.

Get Files and Get Directories need to be changed to

var files = Directory.EnumerateFiles(directory);

and

var names = System.IO.Directory.EnumerateDirectories(directory);
