I think I have a trust issue.......

I am updating an existing module that accept payments and moving it to DNN 5.1.1.  The gateway requires a call to their COM dll to process the payments.  When I run the following:

Dim objEMoney As EM2KEcom.SSCC
Try
    objEMoney = New EM2KEcom.SSCC '<<<<<< error occurs here >>>>>>>>>>
Catch ex As Exception
    Throw ex
End Try

I get the following error:

System.Security.Permissions.SecurityPermission
"Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."


If I run it in "FULL" trust, everything works fine.  If I run it in DNN 4.9, in Medium trust it works fine.

What can I do to solve this?

Hey Kyle,

You mentioned that if you run it in full trust it works fine - I'm assuming that is DNN 5.x? And then you said if you run it in DNN 4.9.x in medium trust it also works fine? That's a little confusing to me - when are you actually seeing the problem?

In the end - if you can run in full trust, you should. It's my understanding that this type of code will not function in medium trust. You can simply comment out the trust="medum" declaration in your web.config and use the code (unless your hosting provider enforces the use of medium trust).

Hope that helps,

Ian

Kyle,

Ian is correct, COM objects require full trust - there is no difference between DotNetNuke versions, this is an asp.net code access security setting. Perhaps your 4.9 site is running under full, it can be set via machine.config as well as web.config . Please note, you mostly need to recycle the application pool after changing trust settings as asp.net needs to unload the application to rebuild the merged configuration.

Thanks for the replies.

But why would it work in one version of DNN and not in another version??

I'm running it on my development box right now.

DNN 4.9.0 --- runs fine in Medium Trust. (<trust level="Medium" originUrl=".*" />)
DNN 05.01.01 (98) --- does not work in Medium Trust.  It does work in Full Trust.

Any ideas?  Both versions would be be using the same machine.config since they are on the same machine.  I've recycled and rebooted.

Assuming that my host will allow full trust, are there any problems running in full trust?
