    <p>From <a href="http://blogs.msdn.com/msdnmagazine/archive/2007/05/16/2675596.aspx" rel="noreferrer">MSDN</a>, </p> <p>In this sample, the Package class is used (as opposed to the ZipPackage.) Having worked with both, I've only seen flakiness happen when there's corruption in the zip file. Not necessarily corruption that throws the Windows extractor or Winzip, but something that the Packaging components have trouble handling.</p> <p>Hope this helps, maybe it can provide you an alternative to debugging the issue.</p> <pre><code>using System; using System.IO; using System.IO.Packaging; using System.Text; class ExtractPackagedImages { static void Main(string[] paths) { foreach (string path in paths) { using (Package package = Package.Open( path, FileMode.Open, FileAccess.Read)) { DirectoryInfo dir = Directory.CreateDirectory(path + " Images"); foreach (PackagePart part in package.GetParts()) { if (part.ContentType.ToLowerInvariant().StartsWith("image/")) { string target = Path.Combine( dir.FullName, CreateFilenameFromUri(part.Uri)); using (Stream source = part.GetStream( FileMode.Open, FileAccess.Read)) using (Stream destination = File.OpenWrite(target)) { byte[] buffer = new byte[0x1000]; int read; while ((read = source.Read(buffer, 0, buffer.Length)) &gt; 0) { destination.Write(buffer, 0, read); } } Console.WriteLine("Extracted {0}", target); } } } } Console.WriteLine("Done"); } private static string CreateFilenameFromUri(Uri uri) { char [] invalidChars = Path.GetInvalidFileNameChars(); StringBuilder sb = new StringBuilder(uri.OriginalString.Length); foreach (char c in uri.OriginalString) { sb.Append(Array.IndexOf(invalidChars, c) &lt; 0 ? c : '_'); } return sb.ToString(); } } </code></pre>

    1. COLooking at that code, I just threw up on my shoes. PackagePartCollection? PartRelationship? PackagePart? Part URIs? ToLowerInvariant? All I wanted was a ZIP FILE...

    2. COYeah, that would be the part the OpenPackage developers seemed to forget. Working with OpenPackage is much more about working with the virtual components, as opposed to the physical representation.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
