Re: User Control Security on .Net 2.0

Ok, if you see my other post I could not see this message. I have fixed that
problem by deleting all messages and reloading them. Anyway, let me post the
info I put in the other one.

Thanks for the reply. I had posted the same question on the 14th but the
Outlook Express news reader will not see it, even if I do a search, so I
would appreciate it if you would add your reply here.

I have been using the 1.1 application for a long time but this model seems
incredibly fragile. I found part of my problem to be I defined one of my
class variables as "private JLReport m_JLReport = null;" This will stop the
app from loading in a web page with .Net 2.0. If I define it as "private
JLReport m_JLReport ;" (no =null) then it loads. Also, I have some problem
with a call to a web service, If you change almost anything the app won't
load.

What I did was create a new web application with just the form and no
functionality. That worked, then I started adding chunks of code from the
app until it failed. This is a really poor way to build an application.

Isn't there any way to drop into the debugger so you can see where it fails?

Right now I have a problem with printing permissions. When I try to set the
printer name on the PrintDocument class I get a security exception say it
could not get the permissions required. I use the attribute
[assembly: PrintingPermissionAttribute(SecurityAction.RequestMinimum, Level
= PrintingPermissionLevel.DefaultPrinting)] but it still won't work.

Now as to your reply, we did not have to create a code group on the clients
machine. We used the 1.1 Wizards to Adjust .Net Security so the Trusted
Sites had Full Trust. I don't see the equivalent Wizard for .Net 2.0. I
will look into code groups and see if they will work.
