System.ExecutionEngineException problem

I have a stable app developed on ASP.NET 1.1 that I'm porting to 2.0.
However, I've noticed that on one page, if I click a button to perform some
business logic (which runs fine), then click on a hyperlink to move to a
different page, I get a 'System.ExecutionEngineException' exception. There
is no line highlighted in the debugger.
I'm not using interop or other threads.
Event viewer shows:
.NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3)
(80131506)
I also sometimes see:
aspnet_wp.exe (PID: 2324) stopped unexpectedly.
It fails predictably on the dev web server in VS2005, less regularly on IIS
(although it does still fail).
I've tried to create a simplified program to reproduce the problem - so far
without success. However I did notice that the problem was worsened by some
code returning an array (15-20) of small Dictionary<> objects. I added a
conversion routine to turn them into arrays of structs, and some of the
problems went away. Is this something to do with memory-shortage' My PC has
800mb, with around 80mb free when running the code.
Whats going on? Is this a bug in .NET2, or is there something stupid in my
code? Advice would be welcome!!
XP Pro sp2, .NET 2.0.50727.42, VS2005, SQL2005
Thanks,
JohnI've reported this to Microsoft, and they can reproduce the problem. I'll
post an update when I know more.

Microsoft report the problems stems back to a Dictionary<decimal,double>
instance.
Looks like the CLR can't cope with this for some reason. Be afraid....

System.Security.SecurityException: Permission denied Error while invoking methods in a Com

Hi,
I am getting an error while trying to create an excel file.
"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: Permission denied"

This is what I am doing. we had an app that was written in VB to take
specific dates and create an excel file.
I am using the dll in my .NET app but it displays the error while writing
the file...

I am sure that I have used regsrv32 to register the DLL

any suggestions,
Stephenyou said you are using the COM server DLL directly in .net? If thats
what you are doing.. you need to create an interop assembly before you
can access the methods in that dll

Please let me know if I understoof your question incorrectly

Are you trying to run the application over the network? If so, see
http://blogs.msdn.com/shawnfa/archi...6/20/57023.aspx. (If you're
using version 2.0 of the .NET framework, ClickOnce is another option for
permissions elevation.)

If you're not attempting to run the applicaiton over the network, could you
please post the complete exception details (including call stack listing),
as returned from its ToString method?

Hi Kumar and Nicole,

This is how I am working on this project. I have a DLL given to me by
another developer that generates Excel files and he created it using VB6.
I registered it on my box, referenced it and I am trying to use it
This is the error I am getting along with stack trace:

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.

It looks like your ASP.NET application is not probably not running with
unrestricted CAS permissions (aka full trust). Unless you have restricted
CAS permissions via your own application's web.config file, adjusting this
is a task for the server administrator. (If you are in shared hosting, it's
likely that the administrator will be unwilling to increase your
application's permissions, and you may need to move to dedicated hosting.)
