Trying in vain to add a chart to a module. B**** permissions!!8/29/2005 7:35:59 AM

0/0

I have just downloaded sasqchart (sasq.co.uk) to try it in a DNN 3.1.1 application being developed under XP Pro, SP2, VS2003. I can add webchartcontrol to the toolbox fine.  However, when I add webchartcontrol from the toolbox to an ascx module, the app will not load. I get the error: Required permissions cannot be acquired.

The error message references machine.config line 198 which is:

<add assembly="*"/>   <=== line 198
</assemblies>

The IIS website is set up for anonymous access via Jxxxx\ASPNET which has full control over c:\dnn311 and subfolders.

sasqchart.dll is currently in c:\program files\sasq (and of course after project build is now in c:\dnn311\bin ).  Does it matter where it is installed?

I also get the same error when trying the chart control from Carlosag.net, so it seems to be to do with permissions (as usual<g>)

Is this likely to be an error with my setup, or a DNN 3.1.1 problem? Any ideas please?

Thank you!

No reply received after 3 days!!

And I was so sure one of you clever people would have some good ideas.  Surely some of you have downloaded a 3rd party DLL and run it from your ASP.NET app??

it's likely to be one of two things

1) code access security permissions. The component may require high or full trust to access various graphics capabilities (lots of these components use dllimport which requires Full trust). Try setting <trust level="Full " in your web.config (note: make sure that machine.config is not setting it to a lower level). You'll have to recycle the web application after making the change i.e. run IISRESET from dos, or else unload the application pool in windows 2003

2) an additional dependancy file is missing. Download http://www.sysinternals.com/Utilities/Filemon.html, and trace what file(s) get accessed, and see if there are errors accessing a file due to it being missing, or lacking permissions.

Thank you very much, Cathal, it proved to be as simple as needing trust to full in web.config(!)  Why didnt I think of that?
