    <p>I have some trouble with the shadow copy feature of AppDomains in combination with a ASP.NET website running under IIS. The problem is that the shadow copied files can not be read or executed by the IIS user because of insufficient permissions.</p> <p>I get the following error message when the code in the new AppDomain is executed (through a callback method via DoCallBack):<br> System.IO.FileLoadException: Could not load file or assembly 'My.Namespace.AssemblyName, Version=0.0.3.2231, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Access is denied.</p> <p>Fusion log: </p> <pre><i>Assembly manager loaded from: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorwks.dll Running under executable c:\windows\system32\inetsrv\w3wp.exe --- A detailed error log follows. === Pre-bind state information === LOG: User = NT AUTHORITY\NETWORK SERVICE LOG: DisplayName = My.Namespace.AssemblyName, Version=0.0.3.2231, Culture=neutral, PublicKeyToken=null (Fully-specified) LOG: Appbase = file:///C:/Inetpub/wwwroot/Web Suite/Widgets LOG: Initial PrivatePath = NULL Calling assembly : (Unknown). === LOG: This bind starts in default load context.

Probing terminated. </i></pre> <p>What I have already done:<br> I have granted the 'C:/Inetpub/wwwroot/Web Suite/Widgets' folder read and execution permission for the user 'NETWORK SERVICE'.<br> When I turn off the shadow copying feature, everything goes fine.<br> Even on my local computer under Visual Studio 2008 it runs without any problem.<br> Granting all files (instead of the folder itself) in the Widgets folder read and execution permission does not solve the problem.</p> <p>I thought it have to do with the permissions on the ASP.NET temporary files folder:<br> C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\web suite<br> This folder, all its sub folders and the files within them have read and read &amp; execute permissions for the user 'NETWORK SERVICE'. So that's not the problem either.</p> <p>To be short:<br> <b>Why can't my site (running under IIS6) access the shadow copied files of the new AppDomain?</b></p>

    2. CONo, I finally decided not to use a separate AppDomain, but use the default ASP.NET AppDomain instead (which already has the shadow copy feature enabled), the only drawback in this solution is that the plugins must be in the bin directory and not a custom dir.

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.
