AccessViolation Exception

Since migrating to .net 2.0 , I repeatedly get Access Violation errors in the
log when tryimg to access vb.net code in a server control from the vb code in
an aspx page.

I have the statement : Imports MyApp.MycontrolName at the top of the vb.net
code

Calls to the server control code work most of the time but occasionally post
the AccessViolation in the log.

Any help would be greatly appreciated.
 
You shouldn't piggy back on another thread btw.

Have a look at your event log? any error messages that seem strange? Are you
doing anything funky in your code that you are not telling us about?

Sorry, didn't realize I was piggy backing. There are messages in the log
showing where in the code the errors are occurring but the code works most of
the time. It really just simple stuff like opening an ADODB Connection
object and using a class to post to an SQL table.
