Custom Delivery Extension - SubscriptionID

I am attempting to implement a custom delivery extension for SSRS 2000. The custom delivery extension will deliver the report to a database(table). CreateSubscription WebMethod returns a SubscriptionID once a subscription is created. Is it possible to get this SubscriptionID at run-time i.e when the IDeliveryExtension.Deliver method is called? If so, how? I want to store the SubscriptionID with the report in the database. Thanks for your help.

Custom Data Extensions Previewing Report

I have created a custom Data extension that returns a dataset through
a datareader. I am attempting to create a report using this extension
as the datasource and am receiving an error when trying to view the
report in Preview. The error is saying it can not find my extension
Datasource.
Any ideas on how to fix this? Or any reasons why this is occuring?
Thanks,

Check out this[0] article, especially about 3/4 of the way down under
"deploying the extension". I'm betting your missing a config file
modification.

Custom Assembly Configuration Problems

Hi,
I am attempting to integrate a third party .Net assembly into a custom
report I'm writing. The assembly provides functions for creating 2D barcodes
that are a required format for my solution. I've successfully referenced the
assembly and can run my report from visual studio without error.
However, when I deploy and run the report I get the following exception:
Failed to load expression host assembly. Details:
System.Security.Permissions.SecurityPermission (rsProcessingError)
I've added the Custom Assemblies block to my RSReportDesigner.config and my
RSReportServer.config. I have also added code groups to my
rssrvpolicy.config and rspreviewpolicy.config. I have deployed the
referenced dlls to the appropriate bin directories.
The only thing that I haven't done is code the custom assembly to 'assert
permissions'. I shouldn't have to because the assembly takes a simple string
and returns the encoded string - it doesn't use any 'secure' resources (no
files, db connections, etc.). I have also tried using 'FullTrust'
permissions in my code groups even though that is not recommended. In any
event, I do not have source code for this third party assembly nor license to
modify it if I could.
Is there anything I can do to make this work?

PaulThe problem is that the third party assembly has strong name and is not
marked with APTCA
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetsec/html/aptcatypes.asp)
The report expressions at runtime are located in an untrusted assembly thus
any call to a non_APTCA assembly would fail. What you need to do is to
create a thin wrapper assembly that would accept calls from report
expressions and redirect them into the non-APTCA assembly. You will also
need to give fulltrust to that wrapper assembly

a clearly identified exception, adding the wrapper class only results in my
expression evaluating to #Error - with no clue as to the cause. My guess is
it's just the same error, only now the exception has been wrapped out of view.
