Thanks Shawn. That helped! Now I'm back to my other problem. My UI object instantiates a "worker" object in another DLL and calls a method in it. The "worker" object instantiates an "Excel Interface" object and calls a method in it. The last method call fails with a "Security error." and the stack trace shows the last method call (from the "Excel Interface" object). But when I debug and step into or set a breakpoint just inside the method itself, I neveractually get inside that method even though the arguments passed to the method are native types (strings, ints and bools). (Note that I can get into the constructor without any trouble, it's just when I try to drill down into that first method that everything stops.)

In my "worker" object, I've created extra methods so that I can "Assert" all the permissions I think I need. I'm "Asserting" a "ReflectionPermission", a "FileIOPermission", a "SecurityPermission", and a "WebPermission" (I'm reading data from a Webservice).

Note that when I run the UI object from a Windows EXE object, everything (of course) works just fine.

Any ideas as to what that "Security Error" might be? (The try/catch catches a "SecurityException" which has "Security Error" for the "Message", the Stack Trace has the method I never get into and and the method with the catch, and blank "PermissionState", "PermissionType" and "PermissionsRefused" properties.)

TIA

>>I've got a web client DLL that I run through IE using the <Object> tag. When I define the Membership Condition using a "Site" or a "URL" in
     mscorcfg, it works (well, part way, see previous post). When I change the Membership condition to a Strong Name, nothing works. The DLL's UI
     doesn't even come up in the browser.
     
     
     
     The structure of the DLLs are as follows: A "UI.dll", which calls a "Doit.dll", which calls a "Util.dll" and the Excel XP PIA dlls. My three dlls are all
     strong-named from the same keypair.snk file. The Excel XP PIAs are also strong-named, by Microsoft. I set up the strong name Memebership
     Condition with just the public key (I grabbed the public key by importing from the "UI.dll")
     
     
     
     Any ideas how I can get this working or how I can trouble-shoot it?
     
     
     
     Thanks!
