All,

I have a C# library serviced component that I am trying to debug from a
ASP.Net page. The C# has the following attributes:

namespace yyyyyy
[assembly: ApplicationAccessControl(false)]
[assembly: Guid("860015D5-B182-4681-90D2-18C1CFFE8EE3")]
[assembly: ApplicationName("xxxxxx")]
[assembly: ApplicationID("88976ED4-61AF-4deb-9023-A81595B5780A")]
[assembly: ApplicationActivation(ActivationOption.Library)]

    [Guid("3BEE7B3D-EE64-435c-B482-5104D84936A7")]
    [EventTrackingEnabled(true)]
    [Transaction(TransactionOption.NotSupported)]
    [JustInTimeActivation(true)]
    [ObjectPooling(true)]
    public sealed class VirusMain : ServicedComponent

When the ASP.Net app tries to create an instance of the component I get the
following error:

Exception Details: System.UnauthorizedAccessException: Access to the
registry key HKEY_CLASSES_ROOT\xxxxxx\xxx is denied.

ASP.NET is not authorized to access the requested resource. Consider
granting access rights to the resource to the ASP.NET request identity.
ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or
Network Service on IIS 6) that is used if the application is not
impersonating. If the application is impersonating via <identity
impersonate="true"/>, the identity will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET write access to a file, right-click the file in Explorer,
choose "Properties" and select the Security tab. Click "Add" to add the
appropriate user or group. Highlight the ASP.NET account, and check the boxes
for the desired access.

Can anyone help?
Thanks

The error message gives you excellent advice. Did you follow it? If you
want your ASP.NET app to call the registry, you have to provide an account
with priveleges to do that.

Hi,

I did follow the message but I am not accessing the registry at all from my
ASP.Net app so that is what is confusing me.

Thanks

Musk,

Yes, you are, in an indirect way. When you auto register your classes
that derive from ServicedComponent, it needs to place entries in the
registry.

Msuk,

You don't place the entries in the registry, .NET does it automatically
for you. That's why I recommended that you manually register the components
with COM+, instead of having .NET do it. You said it worked when you did
that (you couldn't debug, but the components worked).

Msuk,

Have you pre-registered your class with COM+ before you tried to access
the class? This might help, as I am thinking that the ASP.NET process is
trying to auto-register the component.

Hope this helps.

hi,

If I pre-register the C# in COM+ my ASP.Net app calls this and does not step
into the code. I have tried to attach the process but it does not work?

Any ideas?

Msuk,

Honestly, I would not try and debug from within a ServicedComponent. It
is a little buggy (the debug experience).

Rather, I would strip out the code for the object pooling, the
transactioning, etc, etc, and just debug the logic in a harness, and then
adding the aspects (transaction, object pooling, etc, etc).
