Configuration :: How To Security Exception When Accessing C++ DLL
Oct 4, 2010
a C# file in my App_Code folder calls a C++ DLL that is in my BIN folder. I am getting following error:
Security Exception
Description:
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission contact your system administrator or change the application's trust level in the configuration file.
Exception Details: System.Security.SecurityException:
System.Security.Permissions.SecurityPermission
I hosted my application on GoDaddy shared server. They are not allowing me to give full trust to the application by changing setting in my application's web.config file.

I am trying to access unmanaged code(C++) dll in my asp.net web application project. I created a class to access library functions to be able to use in my application. The DLL is located in Bin Folder of my project. I was able to work with it fine on my localhost server but when I try it on the server where the application is hosted, it gives me this error:

I'm having hard time to figure out whats going on with my IIS.My application was running in IIS very well untill I used Visual studio Copy website to update the files in the wwwroot.All of a sudden I got this error.My application works fine from the file system.I tried deleting my application from IIS and uninstalled from control panel and ran the newly built msi/exe but I never got my application back what so ever.This is web.config for reference.I've also tried <trust level="Full"> element but this didn't help.I remember the whole problem started when I was trying to debug the functionality to upload and download files in ASP.Net.

I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

I have a class that derives from System.Web.UI.Page and have set my pages to derive from this custom page class instead of Page. At runtime, the controls are never initialized and throw a NullReferenceException. I've changed some class names and namespaces in the pasted code to protect the innocent. The only thing that I currently override in my PageBase is OnPreLoad and I do call the base.OnPreLoad. I'll eventually add more functionality to this PageBase but for now all that it has is this:

I've tried putting this into a class library (with System.Web referenced) and I've also tried moving the class into the web application and had the same results either way. As another strange twist, I have another class with derives from PageBase called IndexPageBase and it doesn't have this problem:

I am trying to implement the Ajax HtmlEditor into my application. I currently am using a regular TextBox to load and save some data to some EMail template files and had to do some work-arounds to get it to accept the HTML Input. I am trying to upgrade it to use the Editor, but as soon as I insert the Editor and do a PostBack, I receive the Security Exception below. There is absolutely no change to the code-behind, so I don't understand the issue. There is so little on Google for the Version 3.5 Editor that I'm stumped. I have Debugging enabled, but it won't give me the Soruce Error either.

I'm able to browse my website on my IIS through Localhost. However when I try and access it from my own workstation i cannot connect.
How will overcome this issue? It is down to something on the network, or is it something to do with the IIS?

I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.

I am attempting to write an assembly that is hosted by a Web page on IIS. Everything works until I try to read a file from the file system, when I get the following error:

So...I tried the example program found here, which has a similar use:
http://msdn.microsoft.com/en-us/library/system.security.allowpartiallytrustedcallersattribute.aspx
I compiled and published the application, but all I get is a page with a big rectangle and a little icon in the upper left corner, with no error messages. This is the same behavior I get in my own application when I give it a strong name key. (Without the strong name key, it runs properly, but gets the exception above.)
