Needing help at square one

Anonymous — Tue, 28 Dec 2010 15:30:55 GMT

May I bother the group with a square one problem. I see the following error message when attempting to run the first hello world type VB.NET application on a W7 64 machine running AutoCAD 2010. This message occurs when issuing the new command created by the NETLOADed DLL.

"Application attempted to perform an operation not allowed by the security policy. To grant this application the required permission, contact your system administrator, or use the Microsoft .NET Framework Configuration tool."

I take it Microsoft has thrown up another roadblock related to either permissions, registry or both. Specifically what has happened? Does every created DLL need unique permission or does the .NET framework in general need permission? Specifically what needs to be done for the created applications to function unhampered? Whatever the fix, is it required for all computers to run the created application?

Finally, knowing that I do not have administrative rights on my machine and that the "system administrator" is swamped, what methods do I have available to troubleshoot and identify the specific critical conditions that are not present on my machine. For example, would there be readable configuration files somewhere in the labyrinth of folders on my machine from which I could deduce something?

Thanks,aks

Where your .NET dll is loaded into AutoCAD from? From a network share location, or from local drive of the running computer?

If it is the former, you need to learn about .NET code access security and configure the computer for that. Search the Internet for information on CASPOL.exe tool. Alternately, copy the DLL to local disk and load into AutoCAD from there.

Thank you Norman.

The DLL was on the network. Moving it to local solved the problem, but I had to restart AutoCAD. Apparently a subsequent NETLOAD from a local folder did not unload the previous. Is there a "NETUNLOAD" command?

There is no NetUnLoad command (it's a .NET thing, not AutoCAD).

If there is no NetUnload (and inferring there is no NetReload) then are you saying that someone would have to restart the AutoCAD session to utilize a freshly tweaked .NET creation?

yes, AutoCAD has to be restarted to reload your assembly.

It depends on the "tweak".

Visual Studio's "Edit and Continue" is possible for some changes.

Thank you. Can a newly loaded "Assembly02" redefine a command that is defined in an already loaded "Assembly01"?

Yep, you can do that.
