I have a couple of websites with the same hoster that have been setup with 2 different trust levels. One is 'Full' and the other is 'Medium'. I did not realise this because the hoster decided to implement a new security policy and not tell anyone. I only found out when I tried to use the ReportViewer control like I had on the other, older site. Now obviously I am getting the following error message:
Security Exception
Description: The application attempted
to perform an operation not allowed by
the security policy. To grant this
application the required permission
please contact your system
administrator or change the
application's trust level in the
configuration file.Exception Details:
System.Security.SecurityException:
That assembly does not allow partially
trusted callers.
Now what I am wondering is there a way to use the ReportViewer control in a medium trust environment. I've tried reading about this on MSDN but to be honest trying to make head or tails out of Microsoft's documentation has never been something I could get to grips with.
Any help would be greatly appreciated.

I have seen posts that say the Viewer Control will only work in medium trust if you are running in 'remote' mode (as opposed to 'local' mode). I'm also looking for some good code samples on how to do this, and what versions of SQL Server and Visual Studio are required.
