access denied on dll

[Jeremy Ames]

I am trying to move an application from my system to a new test system. I really should have tried an easier program first, but I didn't really have a chance. My application was originally written in ASP.NET 1.1, but was migrated to 2.0 during development. The reason this is an issue is because the application is using the Microsoft.Web.UI.WebControls.dll for the tree view and tab strip controls that didn't exist prior to 2.0. Well, that is where my problem lies. I am getting an access denied message when it is trying to load that dll. I am impersonating a user and I am pretty sure that I have granted access every where that I needed. Please assist.

Here is the ASP.NET error message:
Could not load file or assembly 'microsoft.web.ui.webcontrols' or one of its dependencies. Access is denied.

the application is using the Microsoft.Web.UI.WebControls.dll

This is no longer supported:
http://msdn2.microsoft.com/en-us/library/ms529711.aspx

for the tree view and tab strip controls that didn't exist prior to 2.0.

These now exist natively in ASP.NET 2.0:

http://www.google.co.uk/search?sour...8&rlz=1T4GGIH_en-GBGB220GB220&q=asp+multiview

 

[Jeremy Ames]

I understand that, and it wasn't really supported that well back when I
started using it either. There is a lot of stuff that would require a
rewrite if I did change it. Getting past the obvious, and back to the issue
at hand, what is going on with the security?

 

[Mark Rae [MVP]]

There is a lot of stuff that would require a rewrite if I did change it.

I appreciate that. I used the WebControls on a couple of client projects in
ASP.NET 1.1 and, once I realised that they weren't going to work at all in
v2.0, I upgraded to the new ASP.NET 2.0 controls - took about 5 minutes per
page...

what is going on with the security?

I'm sorry, but I don't know... There have been other threads in here (long
time ago now) where people have tried to use the WebControls in ASP.NET 2.0,
and have given up because they simply don't work...

 

[Jeremy Ames]

Thank you for your response.

I don't think that it was supported when I started using it in the first
place. The real issue is not whether this is supported or not, it is how do
I resolve my access denied problem.

I just put a simple application out there. I had it working until I changed
it to use impersonation, now I am getting the same message. I have given the
specified user access to that folder. What else do I need to do?

 

[Jeremy Ames]

Sorry about the repost... Still getting used to the mail reader.

[Jeremy Ames]

It definitely works. I am running a couple of applications with it in my
test and production environments. This is my first real application with 2.0
and I could not load it into my existing test environment because it is IIS
5.0 with 1.1 applications already running.

 

[Mark Rae [MVP]]

It definitely works.

Really? Fair enough, then...

Maybe somebody else will know how to get it working...

 

[Jeremy Ames]

I don't know if you read my repost from this morning, but I created a simple
application yesterday and installed it on the new test server. I managed to
get the application running, and everything was good until I enabled
impersonation. The application is a "hello world" application so there is
nothing going on behind the scenes.
