Custom Data Extension to SQL Server

Where I work we have custom code to retrieve the connection string. Theprogrammer provides a role and a mode and a connection object isretured. I need similar functionality from Reporting Services and I'mnot sure where to start. I was thinking of passing the role and mode inas username and password under credentials and being able to use thisas my connection to get data for reports. Any help in solving thisproblem would be greatly appreciated.

SQL Server Reporting services is part of SQL Server so you can create roles either with stored procedure or under permissions in Enterprise manager. Hope this helps.

Kind regards,

|||Sorry but you did not understand my post. Please read before replying.As I said we have custom code that we pass a role and mode to that willgive us the CONNECTIONSTRING.

|||I have figured it out and that link doesn't relate to the problem.
I figured out how to do a custom data extension but I am getting astack overflow exception when I try using the extension. I am alsogetting a SecurityPermission exception when I try calling a functionthat uses interop code. So anyone with any ideas to either of theseproblems would be appreciated.

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.
